To investigate the outcomes of patients with ST-elevation myocardial infarction (STEMI) who were treated with coronary artery bypass grafting (CABG) surgery.

Retrospective nationwide cohort study.

Patients with STEMI in Finland who were treated with CABG between January 2004 and December 2018.

1069 patients (mean age: 66.4, 21.4% women).

All-cause mortality (median follow-up 6.4 years) and usage of evidence-based secondary preventive medication early after CABG.

In-hospital mortality among the total cohort was 10.0%, with a significant decrease (p<0.0001) during the study period. Cumulative 10-year mortality was 38.3%. Age, diabetes, renal disease, early surgery, usage of only venous grafts and concomitant procedures were associated with in-hospital mortality in multivariable modelling. Age, cerebrovascular disease, diabetes, heart failure, peripheral vascular disease, rheumatic disease and venous-only grafts were associated with 10-year mortality. Statins and beta blockers were used by >90% of patients and ACE inhibitors/angiotensin II receptor blockers by 70% of patients after discharge from the hospital. The proportion of high-dose statin users increased from 33.1% in 2004-2008 to 63.1% in 2014-2018. ADP inhibitors were used by 29.0% of patients, but the proportion increased during the study.

Contemporary in-hospital and long-term outcomes of CABG-treated patients with STEMI are acceptable. In-hospital mortality has decreased, and the usage of secondary prevention medications after CABG procedures has increased in recent years.

Cardiac injury, encompassing a spectrum of heart muscle damage, requires prompt and accurate diagnosis to improve patient outcomes. Early detection using cardiac biomarkers is vital for timely intervention and reducing mortality. This review highlights the role of high-sensitivity cardiac troponins (hs-cTns) in diagnosing cardiac injury. This article offers an overview of cardiac injury, including its causes, diagnostic challenges, and the evolution of biomarkers, up to the development and commercialization of "high-sensitivity" (hs-) cTns. The molecular structure of cardiac isoforms cTnI and cTnT, release kinetics, guidelines incorporation, diagnostic performance, and clinical application will be analyzed. It is concluded that the advent of hs-cTn assays has further expanded diagnostic capabilities by enabling the detection of low-level cTn elevations, which were previously undetectable using conventional methods. This enhanced sensitivity allows earlier identification of even minor cardiac injuries, facilitating prompt intervention and improving patient outcomes. However, this increased sensitivity also introduces interpretive challenges in understanding the nature of cardiac involvement, especially in distinguishing mild cTn elevations that may signify non-ischemic cardiac injury or be associated with other non-cardiac conditions.

Drug-coated balloons (DCB) have promising results in the management of large coronary artery lesions (CAD), still their role in treating small CAD is not well established. We aimed to provide a comprehensive appraisal of the efficacy and safety of DCBs in patients with small CAD.

We searched PubMed, Scopus, web of science, Ovid, and Cochrane Central from inception until 30 March, 2023. We included all relevant studies that compared DCB versus drug-eluting stents (DES) in small CAD patients undergoing PCI. We reported clinical outcomes as MACE, all-cause death, cardiac death, MI, TLR, TVR, and stent thrombosis, while angiographic outcomes were late lumen loss (LLL), mean lumen diameter (MLD), net luminal gain (NLG), and in-segment binary restenosis.

Twenty studies comprising 18,469 patients were included in this meta-analysis. The incidence rate of MACE was 9.4% in the DCB group compared to 9.9% in the DES group, without a significant difference in the risk of MACE (OR = 0.97, 95% CI: 0.77 to 1.22, p = 0.78). Moreover, DCB significantly decreased MLD and NLG compared to DES, with the following values, respectively (MD= -0.19, 95% CI: -0.32 to -0.06, p < 0.001, and MD -0.21, 95% CI: -0.40 to -0.01, p = 0.04). On the other hand, DCB was associated with higher odds in the risk of in-segment binary restenosis (OR 1.66, 95% CI: 1.03 to 2.68, p = 0.04).

DCB is an alternative approach to DES in the management of small CAD and should be validated in daily clinical practice.

The clinical impact of post-percutaneous coronary intervention (PCI) quantitative flow ratio (QFR) in patients treated with PCI for chronic total occlusion (CTO) was still undetermined.

All CTO vessels treated with successful anatomical PCI in patients from PANDA III trial were retrospectively measured for post-PCI QFR. The primary outcome was 2-year vessel-oriented composite endpoints (VOCEs, composite of target vessel-related cardiac death, target vessel-related myocardial infarction, and ischemia-driven target vessel revascularization). Receiver operator characteristic curve analysis was conducted to identify optimal cutoff value of post-PCI QFR for predicting the 2-year VOCEs, and all vessels were stratified by this optimal cutoff value. Cox proportional hazards models were employed to calculate the hazard ratio (HR) with 95% CI.

Among 428 CTO vessels treated with PCI, 353 vessels (82.5%) were analyzable for post-PCI QFR. 31 VOCEs (8.7%) occurred at 2 years. Mean value of post-PCI QFR was 0.92 ± 0.13. Receiver operator characteristic curve analysis shown the optimal cutoff value of post-PCI QFR for predicting 2-year VOCEs was 0.91. The incidence of 2-year VOCEs in the vessel with post-PCI QFR < 0.91 (n = 91) was significantly higher compared with the vessels with post-PCI QFR ≥ 0.91 (n = 262) (22.0% vs. 4.2%, HR = 4.98, 95% CI: 2.32-10.70).

Higher post-PCI QFR values were associated with improved prognosis in the PCI practice for coronary CTO. Achieving functionally optimal PCI results (post-PCI QFR value ≥ 0.91) tends to get better prognosis for patients with CTO lesions.

The triglyceride-glucose-body mass index (TyG-BMI), a marker for insulin resistance, is recognized for its predictive role in cardiovascular and metabolic diseases, including kidney disease. we explored the TyG-BMI index's association with postoperative kidney injury in coronary artery bypass grafting (CABG) patients, who are at an elevated risk for such complications, underscoring its potential as a predictor for acute kidney injury (AKI).

This single-center, retrospective study included 126 patients. Patients were divided into AKI and non-AKI groups postoperatively according to the KDIGO classification criteria. Univariate logistic regression was used to screen for variables with significant differences (P < 0.01), and multiple multivariate regression models were constructed to analyze independent risk factors in the multivariate regression model and to analyze the value of TyG-BMI in predicting AKI in diabetic patients after CABG.

Compared to the non-AKI group, the AKI group had statistically significant differences in preoperative fasting triglycerides, preoperative fasting glucose, preoperative and postoperative creatinine levels, ICU stay duration, and TyG-BMI levels (P < 0.05). Based on the results of univariate regression analysis, a multivariate logistic regression model A was constructed using all significant variables, and a multivariate logistic regression model 2 was constructed using significant variables other than TyG-BMI. ROC analysis showed that model 2 had better predictive performance than model 1 (AUC = 0.836 vs. 0.766). A positive correlation was observed between TyG-BMI and AKI occurrence (Spearman's correlation coefficient: R = 0.33, P = 0.00019).

Elevated TyG-BMI levels are closely associated with AKI in diabetic patients after CABG. TyG-BMI has potentially predictive value for AKI in diabetic patients after CABG and may play a crucial role in risk stratification in clinical practice.

In primary percutaneous coronary intervention (pPCI), balloon predilation is frequently carried out before stenting but there is a lack of data regarding optimal balloon size and the effect of balloon size on procedural and clinical outcomes.

This study compares small balloon predilation (≤50% of proximal vessel diameter) with large balloon predilation (>50% of proximal vessel diameter) in pPCI.

This multicentre prospective observational study included consecutive ST elevation MI (STEMI) patients undergoing pPCI at three tertiary centres in Egypt. Demographic, clinical and angiographic data were collected for all the patients. The primary outcome was the presence of no reflow at the conclusion of the procedure and secondary outcomes included procedural complications - no reflow, dissection, abrupt vessel closure, fluoroscopy time and procedural time - and clinical outcomes - in-hospital left ventricular ejection fraction (LVEF), cardiogenic shock, stent thrombosis, ventricular fibrillation, stroke, death, ST-segment resolution >50% 1 hour after PCI and LVEF at discharge.

A total of 384 pPCI procedures were included. The small balloon group (n=222) and the large balloon group (n=162) were comparable in terms of baseline characteristics. The large balloon group had a significantly higher incidence of no reflow (n=23 [14.2%] versus n=6 [2.7%], p<0.001), procedural complications: n=31 [19.4%] versus n=10 [4.5%], p<0.001) and contrast volume (190.4 ± 40.2 ml versus 177.4 ± 29.4 ml, p=0.0003) compared to the small balloon group. ST-segment resolution >50% after PCI was more frequent in the small balloon group (n=182 [81.98%] versus n=109 [67.28%], p<0.001).

This study suggests that using a smaller balloon size for predilation in pPCI is associated with improved coronary flow, reduced procedural complications and better ST-segment resolution.

Quantitative flow ratio (QFR) holds significant value in guiding drug-coated balloon (DCB) treatment and enhancing outcomes. However, the predictive capability of post-angioplasty QFR for long-term clinical events in patients with de novo lesions who receive DCB treatment remains uncertain. The aim of this study was to explore the potential significance of post-angioplasty QFR measurements in predicting clinical outcomes in patients underwent DCB treatment for de novo lesions.

Patients who underwent DCB-only intervention for de novo lesions were enrolled. QFR was conducted after DCB treatment. The patients were then categorized based on post-angioplasty QFR. The primary endpoint was major adverse cardiac events (MACE), encompassing all-cause death, cardiovascular death, nonfatal myocardial infarction, stroke, and target vessel revascularization.

A total of 553 patients with 561 lesions were included. The median follow-up period was 505 days, during which 66 (11.8%) MACEs occurred. Based on post-procedural QFR grouping, there were 259 cases in the high QFR group (QFR > 0.93) and 302 cases in the low QFR group (QFR ≤ 0.93). Kaplan-Meier analysis revealed a significantly higher cumulative incidence of MACE in the low QFR group (log-rank P = 0.004). The multivariate Cox proportional hazards model demonstrated a significant inverse correlation between QFR and the occurrence of MACEs (HR = 0.522, 95%CI: 0.289-0.942, P = 0.031). Landmark analysis indicated that high QFR had a significant reducing effect on the cumulative incidence of MACEs within 1 year (log-rank P = 0.016) and 1-5 years (log-rank P = 0.026).

In patients who underwent DCB-only treatment for de novo lesions, higher post-procedural QFR values (> 0.93) were identified as an independent protective factor against adverse prognosis.

In the past 6 years, significant breakthroughs have been achieved in the treatment of heart failure (HF), especially in drug therapy. The classification of chronic HF and the treatment methods for HF and its complications are also constantly being updated. In order to apply these results to the diagnosis and treatment of patients with HF in China and further improve the level of diagnosis and treatment of HF in China, the HF Group of Chinese Society of Cardiology, Chinese Medical Association, Chinese College of Cardiovascular Physician, Chinese HF Association of Chinese Medical Doctor Association, and Editorial Board of Chinese Journal of Cardiology have organized an expert group and update the consensus and evidence-based treatment methods in the field of HF based on the latest clinical research findings at home and abroad, combined with the national conditions and clinical practice in China, and referring to the latest foreign HF guidelines while maintaining the basic framework of the 2018 Chinese Guidelines for Diagnosis and Treatment of HF.

The angiography-derived non-hyperemic pressure ratio (angioNHPR) is a novel index of NHPR based on artificial intelligence (AI) that does not require pressure wires. We investigated the diagnostic accuracy of angioNHPR for detecting hemodynamically relevant coronary artery disease.

In this retrospective single-center study, angioNHPR was assessed using the invasive NHPR as the reference standard. An angioNHPR ≤0.89 was defined as indicative of physiologically significant stenosis. Two angiographic projections ≥30° difference in angulation were selected. The lumen and centerline were automatically segmented by the prototype software, allowing for the calculation of the angioNHPR. We assessed 222 vessels from 178 patients. The accuracy of angioNHPR was 76.6% (95% confidence interval [CI] 70.4-82.0), with sensitivity 66.2% (95% CI 54.0-77.0), specificity 81.5% (95% CI 74.3-87.3), positive predictive value 62.7% (95% CI 53.6-70.9), and negative predictive value 83.7% (95% CI 78.6-87.7). The angioNHPR showed good correlation with invasive NHPR (r=0.72; 95% CI 0.64-0.77; P<0.001), and the agreement between angioNHPR and invasive NHPR was -0.01 (limits of agreement: -0.13, 0.11). The area under the curve (AUC) of angioNHPR was 0.81 (95% CI 0.75-0.86), which was significantly higher than that of 2-dimensional quantitative coronary angiography (AUC 0.69; 95% CI 0.62-0.75; P=0.007).

AI-based angioNHPR demonstrates good diagnostic performance using invasive NHPR as the reference standard.

The ideal revascularization approach for ostial left anterior descending coronary artery (L.A.D.) lesions continues to be a matter of debate. Two primary stenting strategies are often contemplated for managing these lesions: focal ostial stenting (F.O.S.) and the provisional strategy, alternatively termed cross-over stenting (C.O.S.) from the LM to the L.A.D. artery.

Our objective is to assess the efficacy of C.O.S. vs. F.O.S. techniques in patients with ostial L.A.D. lesions who underwent percutaneous coronary intervention (P.C.I.).

We systematically searched five electronic databases to identify relevant studies. The data was pooled as odds ratio (O.R.) with its 95% confidence interval (C.I.) using the DerSimonian-Laird random effect model in STATA 17 MP. Significance was determined by a p-value > 0.05 between intervention subgroups.

Nine articles with a total of 1492 patients were included in the meta-analysis. The pooled O.R. for Major Adverse Cardiovascular Events (MACE) was 0.88 (95% C.I. [0.39, 1.99], P = 0.76), indicating comparable rates between F.O.S. and C.O.S. For all-cause death, the O.R. was 1.46 (95% C.I. [0.53, 4.02], P = 0.46), with no significant differences between the compared techniques. Cardiovascular death showed no preference between treatments (O.R.=0.99, 95% C.I. [0.30, 3.31], P = 0.99), and similarly for myocardial infarction (O.R.=0.74, 95% C.I. [0.38, 1.44], P = 0.37).

Our meta-analysis comparing C.O.S. and F.O.S. for L.A.D. lesions revealed similar efficacy in clinical and angiographic outcomes.

The objective was to evaluate the relationship between carotid stenting and off-pump coronary artery grafting (CAS-OPCABG) and OPCABG only in patients with asymptomatic severe carotid stenosis.

This study retrospectively included 669 patients with asymptomatic severe carotid artery stenosis who underwent OPCABG at multiple centers. After propensity score matching for baseline characteristics, the study compared two groups of patients with clinical data, early and midterm death, stroke, and myocardial infarction (MI).

After matching, there was no significant difference between two groups at baseline. The rates of early stroke, midterm stroke, and intensive care unit (ICU) stay were significantly lower in the CAS OPCABG group, yet the use of the internal mammary artery (IMA) was comparatively lower. Kaplan-Meier analysis revealed that there was no significant difference in midterm mortality between two groups. In the bilateral asymptomatic carotid stenosis subgroup, the early stroke rate was significantly lower after CAS-OPCABG, but there was no significant difference in the unilateral carotid stenosis subgroup. Multivariate logistic regression analysis identified previous atrial fibrillation, previous stroke, aortic atherosclerosis, bilateral carotid stenosis and the use of an intra-aortic balloon pump (IABP) as significant risk factors for early postoperative stroke, CAS emerged as a protective factor. Use of IMA was found to be a protective factor against postoperative mortality.

CAS-OPCABG is an efficacious and safe approach for the treatment of asymptomatic severe carotid artery stenosis, effectively decreasing the incidence of postoperative stroke.

Elevated homocysteine (Hcy) levels have been linked to poorer outcomes in acute coronary syndrome. This study aimed to assess the predictive value of elevated Hcy levels for major adverse cardiac events (MACE) in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI).

This retrospective cohort study included 183 STEMI patients who underwent primary PCI at a tertiary university hospital in southern China from January 2020 to December 2021. Laboratory values, including Hcy levels, were obtained within 24 hours of admission. Patients were categorized into elevated and normal Hcy groups using a threshold of 12 μmol/L. The study outcome was the occurrence of 6-point MACE, defined as cardiac death, nonfatal myocardial infarction, stroke, ischemia-driven revascularization (PCI or coronary artery bypass grafting), heart failure and all-cause death. Survival analyses were conducted using Kaplan-Meier and Cox proportional hazard methods. Propensity score matching (PSM) and inverse probability of treatment weighting (IPTW) approaches were employed to minimize bias.

The mean age of the patients was 64.8 years, with 76.0% being male. After adjusting with PSM or IPTW, covariate imbalances between the two groups were corrected. Over a median follow-up period of 25.8 months, 55 MACE events occurred, resulting in an event rate of 30.1%. Patients with elevated Hcy levels had a higher incidence of MACE in both unadjusted (hazard ratio [HR] = 2.778; 95% confidence interval [CI]: 1.591-4.850; p < 0.001) and adjusted analyses (PSM: HR = 2.995; 95% CI: 1.397-6.423, p = 0.005; IPTW: HR = 3.2; 95% CI: 1.631-6.280, p < 0.001). Multivariate Cox regression further confirmed that elevated Hcy levels were associated with a worse prognosis across the entire cohort (HR = 1.062, 95% CI: 1.029-1.097, p < 0.001), PSM cohort (HR = 1.089, 95% CI: 1.036-1.145, p < 0.001), and IPTW cohort (HR = 1.052, 95% CI: 1.020-1.086, p = 0.001).

Elevated plasma levels of Hcy (≥12 μmol/L) are associated with worse outcomes in STEMI patients undergoing primary PCI, highlighting the potential role of Hcy as a prognostic marker in this population.

The correlation between cardiopulmonary exercise testing (CPET) parameters and the prognosis of patients undergoing percutaneous coronary intervention (PCI) with high pulse pressure (PP) is unclear. The purpose of present study is to investigate the correlation of CPET parameters in patients under PCI with high PP and assess their reference value for prognosis.

Individuals aged 18 years and older who were diagnosed with coronary artery disease (CAD) and underwent PCI along with CPET from November 1, 2015 to September 30, 2021 were enrolled. The patients were categorized into two groups based on PP: high PP group (PP of males ≥50 mmHg; PP of females ≥60 mmHg) and normal PP group (PP of males <50 mmHg; PP of females <60 mmHg). The primary endpoint was major adverse cardiovascular events (MACE). The optimal predictors of MACE were identified through Cox regression analysis. The time-dependent receiver operating characteristic (ROC) curves were generated and the area under the ROC curve (AUC) was measured to evaluate the discriminatory ability in patients with high PP.

A total of 2785 patients were included in present study, with a median follow-up period of 1215 (687-1586) days. Through multifactorial analysis, it was determined that peak oxygen uptake (peak VO2, hazard ratio (HR): 0.94, 95% confidence interval (95% CI): 0.88 to 1.00, p = 0.038) and ventilatory equivalent for carbon dioxide (VE/VCO2, HR: 1.08, 95% CI: 1.02 to 1.15, p = 0.007) are important predictive factors in the parameters of CPET. The ROC based on diabetes mellitus (DM), smoking, peak VO2, and VE/VCO2 could effectively evaluate the prognosis of patients [1-year AUC: 0.636 (0.515~0.758), 3-year AUC: 0.675 (0.599~0.752), 5-year AUC: 0.718 (0.607~0.830)].

The prognosis of CAD patients with high PP was worse compared to the patients with normal PP. The peak VO2 and VE/VCO2 were predictors of MACE in CAD patients with high PP.

ST-elevation myocardial infarction (STEMI) is one of the most prevalent presentations in young patients. It is essential to emphasise that each minute of delay in providing medical care is negatively correlated to the patient's prognosis. The present study was carried out to evaluate the ischaemia-reperfusion times in patients ≤40 years of age versus individuals >40 years of age and their association with mortality and major adverse cardiac event (MACE) over the long term.

A retrospective, multicentre cohort study was carried out in 6799 patients diagnosed with STEMI. Two groups were established: patients diagnosed with STEMI and aged >40 years, and patients diagnosed with STEMI and aged ≤40 years.

The patients in the young group had a significantly sooner electrocardiographic diagnosis than the patients >40 years of age. A delay was observed in females, with a relative risk (RR) of 1.21 (95% CI 1.13 to 1.30) (p<0.001). Presenting dyspnoea (RR 1.76, 95% CI 1.5 to 2.06) (p<0.001) or going to a hospital without haemodynamics (RR 1.55, 95% CI 1.45 to 1.67) (p<0.001) was related to increased delay. The occurrence of MACE in the first year of follow-up was related to different risk factors, along with a delay in healthcare (HR 1.25, 95% CI 1.10 to 1.54) (p<0.042).

This study shows that young patients with STEMI tend to receive a sooner diagnosis than older individuals. Delays in healthcare represent one of the main factors related to the occurrence of MACE and non-event-free survival.

Diffuse coronary artery disease (CAD) impacts the immediate hemodynamic and clinical outcomes of percutaneous coronary intervention (PCI). We evaluated whether the diffuse pattern of CAD derived from angiographic Quantitative flow ratio (QFR) impacts the immediate hemodynamic outcome post-PCI and the medium term predicted vessel-oriented composite endpoint (VOCE). Paired pre-procedure QFRs were assessed in 503 patients and 1022 vessels in the Multivessel TALENT (MVT) trial. The pathophysiological pattern of CAD was defined as "predominantly diffuse" or "focal" according to a virtual QFR pullback pressure gradient (PPG) index < 0.78 and ≥ 0.78, respectively. Physiological "focal severity" was assessed using the QFR gradient per mm (dQFR/ds), with a value ≥ 0.025/mm the threshold for a "major gradient". A post-PCI QFR ≥ 0.91 was considered optimal. Median pre-PCI PPG index was 0.70 (IQR 0.59-0.80). The prevalence of "predominantly diffuse" CAD and "major gradient" were 68.6% and 85.8%, respectively. A "Predominantly diffuse" pattern with a major gradient had a higher risk of a post-PCI QFR < 0.91 (OR 1.52,95%CI 1.47-1.58). In multivariable analysis, low QFR PPG index (diffuse disease) was an independent determinant of a post-PCI QFR < 0.91 (per 0.1 decrease of QFR PPG index, OR:9.8, 95% CI 3.0-32.2, p < 0.001). Based on post-PCI QFR the predicted 2-year VOCE, a powered endpoint in the MVT trial, was 6.1% and 4.2% in diffuse and focal lesions, respectively. A pre-procedure physiological pattern of diffuse CAD is an independent determinant of an unfavourable immediate hemodynamic outcome post-PCI, and detrimentally affects the predicted 2-year VOCE.Clinical Trial Registration URL: https://www.clinicaltrials.gov/ct2/show/NCT04390672 Unique Identifier: NCT04390672 (registration date 15/05/2020).

Ultrathin-strut stents (UTS) represent a significant advancement in percutaneous coronary intervention. This study aimed to evaluate the safety and short- to mid-term outcomes of stenting with the thinnest struts on the market (50 µm) using a biodegradable everolimus-eluting polymer (Evermine 50) in real-world patients with coronary artery disease.

A single-arm, multicenter, prospective study was conducted in real-world patients. A total of 161 patients with de novo lesions who received at least 1 UTS stent were enrolled. The primary safety endpoint was the occurrence of major adverse cardiovascular events, defined as cardiac death, target-vessel myocardial infarction, or the need for revascularization of the target lesion at 12 months. The incidence of stent thrombosis at 12 months was also analyzed.

The study included 161 patients with a mean age of 64 ± 14 years; 79% were male, 34% had diabetes, and 66% had hypertension. The most common indication for intervention was non-ST-segment elevation myocardial infarction (42%), followed by ST-segment elevation myocardial infarction (22%). The procedural success rate was 100%. At 12 months of follow-up, the incidence of MACE was 2.5%, and the definite stent thrombosis rate was 1.3%.

The use of the 50 µm UTS stent with a biodegradable everolimus-eluting polymer demonstrated a favorable safety profile and good clinical outcomes in unselected patients at 1 year of follow-up.

Few reports have provided detailed characteristics of incident coronary artery disease (CAD) and its risk factors in patients undergoing ablation (ABL) for atrial fibrillation (AF).Patients undergoing ablation for AF with no documented CAD were retrospectively studied at our institution. Patients were divided into 2 groups: those in whom significant stenosis was detected incidentally on coronary angiography (CAG) performed at the same time as ablation, and those without. The detection rate and its predictors were examined.Of the 550 patients, 20 had incidental CAD (detection rate: 3.6%). We compared the clinical data between these 20 patients (ABL-CAD group) and the 530 patients who displayed no significant stenosis on CAG. In multivariate analysis, age, hemoglobin A1c (HbA1c), and high-density lipoprotein cholesterol (HDL-chol) were predictive factors (odds ratio: 1.08, 2.43, 1.58, 95% CIs: 1.01-1.14, 1.53-3.86, 0.92-0.99; P = 0.014, 0.004, 0.024, respectively) for identification of CAD. Multivariate analysis based on cut-off values from receiver operating characteristic analysis identified age, HbA1c ≥ 6.1%, and HDL-chol ≤ 49 mg/dL as predictors (odds ratios: 1.06, 4.04, 3.07; 95% CIs: 1.00-1.12, 1.58-10.3, 1.1-8.01; P = 0.04, 0.01, 0.021, respectively). The area under the curve was significantly greater for age and HbA1c ≥ 6.1% and HDL-chol ≤ 49 mg/dL than for age alone (0.810 versus 0.672; P = 0.005).Patients undergoing ablation for AF appear likely to have CAD if HbA1c is ≥ 6.1% and HDL-chol is ≤ 49 mg/dL.

In elderly and frail patients, there is limited evidence on the therapeutic management of left main coronary artery (LM) disease. The objective of this study was to evaluate mid-term clinical outcomes in older adults undergoing percutaneous coronary intervention (PCI) of LM.

We conducted a retrospective study including all older patients (≥ 75 years) undergoing LM-PCI at a high-volume center between 2017 and 2021. The primary endpoint was a composite of major adverse cardiovascular events (MACE). Patients were grouped according to the presence of frailty based on the FRAIL scale. Inverse probability of treatment weighting was used to account for clinical differences between the 2 groups.

A total of 140 patients were included in the study (median age 80 [78-84]; 36% women). Of them, 49% met the criteria for frailty. After a median follow-up of 19 [5-35] months, 40 MACE (29%) were recorded. The all-cause death rate was 32%. There were no differences in the risk of MACE between frailty groups, but patients with frailty had an increased risk of all-cause mortality (HRadj, 1.95 [1.02-3.75]; P = .046).

LM-PCI in older adults with multiple associated comorbidities could be considered a feasible option in this special population. The rate of MACE at follow-up was acceptable. Frailty was associated with a worse prognosis in terms of all-cause mortality at follow-up.

The use of transradial access for percutaneous coronary procedures has increased due to its advantages over the femoral approach. However, this benefit comes at the expense of a higher rate of radial artery occlusion (RAO). Our objective was to assess the incidence and predictors of RAO following transradial catheterization. Additionally, we studied anatomic variations of the radial artery (RA).

This prospective study enrolled 427 patients who underwent coronary angiography or angioplasty via transradial access. The forearm arteries were evaluated by ultrasound. If RAO was present, follow-up ultrasound examinations were performed at 1 and 3 months postprocedure.

Our study population included 288 men (67.4%) and 139 women (32.6%). The mean age was 61.9 ± 11.1 years. RAO occurred in 48 patients (11.24%), and spontaneous recanalization was observed within 3 months in 15 patients (32.6%). On multivariate analysis, independent predictors of RAO were younger age (OR, 0.642; 95%CI, 0.480-0.858; P = .031), low periprocedural systolic blood pressure (OR, 0.598; 95%CI, 0.415-0.862; P = .007), a small radial diameter (OR, 0.371; 95%CI, 0.323-0.618; P = .031), insufficient anticoagulation (OR, 0.287; 95%CI, 0.163-0.505; P < .001), occlusive hemostasis (OR, 0.128; 95%CI, 0.047-0.353; P < .001), and long duration of hemostasis. The overall incidence of RA anatomic variations was 14.8% (n = 63). Among these, 40 patients (63.5%) had a high radial origin, 18 (28.6%) had extreme RA tortuosity, and 5 (7.9%) had a complete radioulnar loop.

The main modifiable predictors of RAO are insufficient heparinization and occlusive hemostasis. Preventive strategies should focus primarily on these 2 predictive factors to reduce the risk of RAO.

Contrast-induced acute renal injury is the third leading cause of hospital-acquired acute kidney injury. Our trial aimed to compare high-dose statin versus statin plus N-acetylcysteine (NAC) to prevent contrast-induced nephropathy.

Randomized control trial included patients who undergoing elective percutaneous coronary intervention (PCI) at Alshifa Hospital in Gaza, the first group (statin: 50 patients) received 80 mg of atorvastatin orally once daily for 3 days. The second group (statin + NAC: 50 patients) received 80 mg of atorvastatin orally once daily for 3 days, plus NAC 1200 mg orally twice daily every 12 h for 2 days. All patients underwent measurement of serum creatinine and urea level before PCI and 2-3 days after the procedure. The primary endpoint was to compare development of contrast-induced nephropathy between the two groups.

The total group comprised 100 patients: 71 male patients and 29 female patients. Mean age was 59 ±9.8 years. After intervention serum creatinine decreased from 1.02 ±0.27 mg/dl to1.01 ±0.29 mg/dl in the statin group, while it decreased from 1.08 ±0.36 mg/dl to 0.92 ±0.13 mg/dl in the statin + NAC group. The difference between the two groups was significant (p = 0.048). Also, the urea plasma level in the statin group decreased from 34.5 ±9.7 mmol/l to 30.6 ±8.7 mmol/l after PCI, while in the statin + NAC group it decreased from 36.4 ±9.9 mmol/l to 26.2 ±10.6 mmol/l; the difference between the two groups was significant (p = 0.017). Contrast-induced nephropathy was seen in 9 (18%) patients in the statin group and in 2 (4%) patients in the statin + NAC group (p = 0.025).

The combination of high-dose atorvastatin plus NAC compared to atorvastatin alone was associated with a significant reduction of contrast-induced nephropathy in patients undergoing PCI.

To study the associations between risk factors, clinical characteristics, severity of brachiocephalic artery (BCA) atherosclerosis and severity of coronary artery (CA) disease in patients with acute coronary syndrome (ACS).

The study included patients with any type of ACS and obstructive coronary artery disease confirmed by coronary angiography. A quantitative analysis of coronary angiography data was performed with an assessment of the number of CAs with significant stenosis and calculation of the SYNTAX score. The major clinical and laboratory parameters that are risk factors for atherosclerosis and/or affect the cardiovascular prognosis were assessed; for patients with ACS without ST segment elevation (NSTE-ACS), the risk score was calculated by the GRACE scale. The BCA ultrasound examination was performed with a quantitative analysis of atherosclerotic burden.

The study included 312 patients aged 64 [56, 72] years; the proportion of men was 69.2%. The frequency of lesions of 1, 2 and 3 coronary arteries was 34.6, 35.3, and 30.1%, respectively; the SYNTAX score was 14 [9, 21]. According to the results of univariate analysis, the number of stenotic CAs and the SYNTAX score were associated with age, smoking history, history of ischemic heart disease, diabetes mellitus (DM), the presence of non-stenotic CA lesions, the GRACE score in NSTE-ACS, and the Charlson comorbidity index. An inverse correlation was found for the level of physical activity and a slightly weaker one for the glomerular filtration rate and high-density lipoprotein cholesterol (HDL-C). In multivariate models, the only independent predictors of the number of stenotic CAs were HDL-C (odds ratio, OR 0.37, 95% confidence interval, CI 0.17-0.81; p=0.012) and the smoking history (OR 1.30, 95% CI 1.12-1.52; p=0.001), a coefficient of determination of the model R2 of 18%, SYNTAX score with a history of myocardial infarction (ß=6.40, 95% CI 3.22-9.58; p<0.001), insulin-dependent DM (ß=9.44, 95% CI 3.50-15.38; p=0.002), GRACE score for NSTE-ACS (ß=0.06, 95% CI 0.01-0.11; p<0.014), and a coefficient of determination of the model R2=20%.

Patients with ACS show significant, independent associations of the severity of coronary atherosclerosis with HDL-C, smoking duration, history of myocardial infarction, insulin-dependent diabetes, and the GRACE score in NSTE-ACS. Variability in the severity of CA lesions is only to a small extent determined by risk factors, clinical characteristics, and the severity of concomitant carotid atherosclerosis.

Evaluation of the clinical and diagnostic role of stepwise stress echocardiography (Stress Echo) with exercise using the ABCDE protocol in patients with myocardial infarction (MI).

This single-site study included 75 patients (mean age 61.6±9.8 years; 84% men) after MI. The median time since MI was 1231.0 [381.5; 2698.5] days. All patients underwent Stress Echo using a five-step protocol. Step A identified impaired local contractility, step B identified the sum of B lines, step C identified the left ventricular (LV) contractile reserve, step D identified the coronary reserve in the anterior interventricular branch, and step E identified the heart rate reserve. The Stress Echo result was assessed by scores from 0 (all steps negative) to 5 (all steps positive). The effects of positive steps and the sum of Stress Echo scores on the incidence of the need for repeat revascularization were assessed.

The frequency of positive results was 36% for step A, 18.7% for step B, 80.0% for step C, 53.3% for step D, and 50.7% for step E. In 4 (5.3%) patients, all steps were negative (score 0); in 3 patients (4%), they were positive (score 5). Coronary angiography after Stress Echo during the follow-up period was performed in 26 (34.7%) patients; the need for repeat revascularization was determined in 17 (22.7%) patients. The predictors of the need for repeat revascularization according to a multivariate analysis were positive step A, chest pain pattern, and LV end-diastolic volume at peak exercise (p<0.001). A statistically significant effect of positive step A on survival without a need for repeat revascularization was observed in patients with a history of MI (p=0.020).

Among all the parameters of the integrated approach with Stress Echo, the emergence of new areas of impaired LV local contractility in patients after MI remains the main guideline for prescribing an angiographic study and a significant predictor of a need for repeated revascularization. However, the study results suggest that a further investigation of the effect of each positive step and the total ABCDE Stress Echo score on the prognosis for postinfarction cardiovascular complications is promising.

In-stent restenosis (ISR) remains the predominant cause of stent failure and the most common indication for repeat revascularization. Despite technological advances in stent design, ISR continues to pose significant challenges, contributing to increased morbidity and mortality among patients undergoing percutaneous coronary interventions. In the last decade, intravascular imaging has emerged as an important method for identifying the mechanisms behind ISR and guiding its treatment. Treatment options for ISR have expanded to include balloon angioplasty, cutting or scoring balloons, intravascular lithotripsy, atheroablative devices, drug-eluting stents, drug-coated balloons, surgical revascularization, and intravascular brachytherapy. The aim of the current review is to describe the classification and mechanisms of ISR, provide a comprehensive and updated overview of the evidence supporting different treatment strategies, suggest a management algorithm, and present insights into future developments in the field.

Patients suffering from acute myocardial infarction complicated by cardiogenic shock (AMICS), who undergo veno-arterial extracorporeal membrane oxygenation (VA-ECMO) therapy, typically exhibit high mortality rates. The benefits of percutaneous coronary intervention (PCI) in these patients remains unclear. This study aims to investigate whether PCI can mitigate mortality among patients with AMICS supported by ECMO.

Data from patients ≥18 years, who underwent VA-ECMO assistance in China between January 1, 2017, and June 30, 2022, were retrieved by searching the Chinese Society of Extracorporeal Life Support (CSECLS) Registry. A total of 1623 patients were included and categorised based on whether they underwent PCI. Using propensity score matching, 320 patient pairs were successfully matched. The primary outcome was in-hospital mortality rate. The secondary outcomes included VA-ECMO duration, Hospital stay, ECMO weaning and ECMO related complications.

In the cohort of 1623 patients, 641 (39.5%) underwent PCI. Upon conducting multivariate logistic regression analysis, it was observed that those who underwent PCI had a lower prevalence of hyperlipidemia (13.1% versus [vs.] 17.8%), chronic respiratory disease (2.5% vs. 4.3%) and lower lactic acid (5.90 vs. 8.40). They also had a more significant history of PCI (24.8% vs. 19.8%) and were more likely to be smokers (42.6% vs. 37.0%). Patients in the PCI group exhibited lower in-hospital mortality before and after matching (40.3% vs. 51.6%; p = 0.005), which persisted in multivariable modeling (adjusted odds ratio [aOR]: 0.69; 95% confidence interval 0.50-0.95; p = 0.024). Patients who received PCI were more successfully weaned from ECMO (88.6% vs. 75.8% before matching). PCI was not a risk factor for ECMO related complications.

Among patients who received ECMO support for AMICS, PCI was associated with a lower rate of in-hospital mortality.

Light transmission aggregometry (LTA) is a method used to investigate platelet functions in platelet-rich plasma (PRP), notably when screening for platelet disorders. Various national guidelines and recommendations help in setting up the LTA test in specialized laboratories. However, due to the nature of the sample matrix and its subsequent specificities, more accurate positions are needed to achieve LTA accreditation according to the standard NF EN ISO 15 189. We reviewed guidelines and recommendations as they can be useful in the accreditation process, and we conducted a survey on LTA practice among members of the Société Française de Thrombose et d'Hémostase (SFTH) in 2021. We formulated 28 proposals, which have been approved by vote within the SFTH. All aspects to take into consideration for the proper conduct of LTA assays and their accreditation have been covered. Notably, preanalytical, analytical and postanalytical aspects are depicted, including blood sampling, PRP preparation, instruments, agonists, performance assessment, personnel training and data interpretation. This document, essentially representing a French position paper on the current recommendations and subsequent proposals for LTA accreditation, might prove useful also outside France for relevant laboratories and auditors involved in LTA accreditation.

Because of the limitations in new-generation drug-eluting stents (DES), treatments advocating for non-stents with a drug-coated balloon (DCB) is now of great interest. Here, we conducted a meta-analysis to testify whether a DCB was more effective and safer than a DES in treating de novo coronary artery disease (CAD).

We searched PubMed, Embase, Cochrane Library, and Web of Science to obtain high-quality trials comparing DCB with DES for the treatment of de novo CAD. The primary endpoint was target lesion revascularization (TLR), and the secondary endpoints were in-lesion late lumen loss (LLL), all-cause death, myocardial infarction and binary restenosis.

We enrolled 1661 patients from seven randomized clinical trials. Compared with the DES group, the MD (mean difference) of in-lesion LLL was significantly lower in the DCB group (MD -0.19, 95% CI -0.23 to -0.16, p < 0.00001, I2 = 0%). The DCB group showed superiority in small vessel disease (SVD) in in-lesion LLL (MD -0.21, 95% CI -0.34 to -0.08, p = 0.001).

The DCB group exhibited a lower in-lesion LLL compared to the DES group, and DCB was not inferior to DES in other endpoints, including in the SVD subgroup. Hence, to our knowledge, DCB is non-inferior to DES for de novo CVD and SVD. DCB in patients with CVD needs further large and long-term clinical trials to demonstrate its long-term efficacy.

Traditionally, coronary angiography was restricted to visual estimation of contrast-filled lumen in coronary obstructive diseases. Over the previous decades, considerable development has been made in quantitatively analyzing coronary angiography, significantly improving its accuracy and reproducibility.  Notably, the integration of artificial intelligence (AI) and machine learning into quantitative coronary angiography (QCA) holds promise for further enhancing diagnostic accuracy and predictive capabilities. In addition, non-invasive fractional flow reserve (FFR) indices, including computed tomography-FFR, have emerged as valuable tools, offering precise physiological assessment of coronary artery disease without the need for invasive procedures. These innovations allow for a more comprehensive evaluation of disease severity and aid in guiding revascularization decisions. This review traces the development of QCA technologies over the years, highlighting key milestones and current advancements. It also explores prospects that could revolutionize the field, such as AI integration and improved imaging techniques. By addressing both historical context and future directions, the article underscores the ongoing evolution of QCA and its critical role in the accurate assessment and management of coronary artery diseases. Through continuous innovation, QCA is poised to remain at the forefront of cardiovascular diagnostics, offering clinicians invaluable tools for improving patient care.

Glycated albumin (GA) has been demonstrated to be associated with adverse outcomes in patients with acute coronary syndrome (ACS). However, as a specific subgroup of ACS, a significant proportion of patients with ACS without standard modifiable cardiovascular risk factors (SMuRFs) are currently being identified. The prognostic value of serum GA for adverse events in such patients remains unexplored. This study aims to evaluate the prognostic value of GA in predicting adverse outcomes in patients with ACS without SMuRFs.

This retrospective study involved 1,140 consecutive patients who were diagnosed with ACS without SMuRFs at the Beijing Anzhen Hospital between May 2018 and December 2020 and underwent coronary angiography. Each patient was followed up for a period of 35-66 months after discharge. The primary endpoint of this study was major adverse cardiovascular and cerebrovascular events (MACCEs) that included all-cause mortality, non-fatal myocardial infarction, non-fatal ischemic stroke, and ischemia-driven revascularization.

The average age of the study participants was 59.55 ± 10.98 years, and men accounted for 61.8%. The average GA level was 14.37 ± 2.42. The median follow-up duration was 48.3 months, during which 220 cases (19.3%) experienced MACCEs. In the fully adjusted model, with GA as a continuous variable, the hazard ratio (HR) for MACCEs in the high GA group was 1.069 (95% confidence interval (CI): 1.008, 1.133), the HR for ischemia-driven revascularization was 1.095 (95% CI: 1.021, 1.175), and the HR for all-cause mortality was 1.155 (95% CI: 1.021, 1.306), all with P values less than 0.05. Similarly, when GA was considered as a categorical variable, in the fully adjusted model, GA was associated with MACCEs, ischemia-driven revascularization, and all-cause mortality, with P values all less than 0.05. The restricted cubic spline curve showed that the relationship between GA and MACCEs was linear (p for non-linear = 0.079; p for overall association = 0.026). Furthermore, GA levels were correlated with poor prognosis in the subgroups of patients.

Serum GA might be an independent predictor of all-cause death and ischemia-driven revascularization in patients with ACS without SMuRFs.

Percutaneous coronary intervention (PCI) with drug-eluting stents (DES) in complex coronary artery disease (CAD) has been established as the standard of care, but stent-related events are not uncommon. Sirolimus-Coated Balloon (SCB)-based angioplasty is an emerging technology, although it needs to be thoroughly evaluated compared with DES in the complex PCI setting. This study aimed to investigate the safety and efficacy of SCB-based angioplasty compared with new-generation DES in complex PCI.

Net adverse cardiovascular events (NACE: all-cause death, target lesion revascularization, non-fatal myocardial infarction, and major bleedings according to BARC classification), as a primary study endpoint was compared between SCB and new-generation DES for complex coronary lesions.

Among 1782 patients with complex CAD, 1076 were treated with a sirolimus-coated balloon (EASTBOURNE Registry) and 706 with new-generation DES (COMPLEX Registry). After propensity score matching, a total of 512 patients in both groups were analyzed. NACE occurred more significantly in the DES group during the 1-year follow-up (10.5% vs. 3.9%, p = 0.003), mainly due to a higher risk of bleeding (6.6% vs. 0.4%, p = 0.001). The Cox model adjusted for lesion length showed a significantly lower hazard of NACE (HR: 0.23, CI [0.10, 0.52], p < 0.001) and all-cause mortality (HR: 0.07, CI [0.01, 0.66], p = 0.020) in SCB compared to DES group.

SCB angioplasty has an advantage over DES for the treatment of complex CAD regarding NACE, significantly reducing the incidence of major bleeding without increasing ischemic endpoints. SCB may be an alternative to DES in selected patients with complex coronary lesions.

Ischemic heart disease (IHD) with severe coronary artery disease (SYNTAX score >22 points) in combination with various comorbidities is often a reason for refusal of coronary artery bypass grafting in such patients. Thus, a new term has emerged, "high-risk percutaneous coronary intervention"; however, the criteria, indications and results of these interventions have not yet been sufficiently studied. Therefore, according to current clinical guidelines, the treatment tactics for this patient cohort is determined by the decision of a council, the so-called Heart Team. This analytical review summarizes the criteria for high-risk percutaneous coronary interventions based on the literature, and describes the effect of various comorbidities on the results of direct myocardial revascularization.

The article presents a clinical case of perioperative non-ST-segment elevation myocardial infarction in a patient with primary metasynchronous cancer of the rectum, stomach and bladder, which developed during simultaneous surgical intervention in the volume of proximal gastrectomy and abdominoperineal extirpation of the rectum. Fluctuations in blood pressure and imbalance in the hemostasis system at the stages of anesthesia and surgery in a patient with severe systemic atherosclerosis caused the development of myocardial ischemia in the area of significant coronary stenosis. Emergency coronary angiography detected subtotal stenosis of the anterior descending artery; stenting of the affected area of the coronary artery was performed. Monitoring of hemodynamic parameters and changes in the hemostasis system during the optimal antianginal therapy allowed to bring the patient out of critical condition and discharge him from the hospital on the 18th day.

Studies on the relationship between the preoperative quantitative flow ratio (QFR) and parameters of intraoperative transit time flow measurement (TTFM) are extremely rare. In addition, the predictive value of QFR and TTFM parameters for early internal mammary artery (IMA) failure after coronary artery bypass grafting still needs to be validated.

We retrospectively collected data from 510 patients who underwent in situ IMA grafting to the left anterior descending (LAD) artery at Fuwai Hospital. Spearman correlation coefficients between preoperative QFR of the LAD artery and intraoperative TTFM parameters of the IMA were -0.13 (P=0.004) for mean graft flow (Qm) and 0.14 (P=0.002) for the pulsatility index (PI). QFR and TTFM exhibited similar and good predictive value for early IMA failure (5.7% at 1 year), and they were better than percentage diameter stenosis (area under the curve 0.749 for QFR, 0.733 for Qm, 0.688 for PI, and 0.524 for percentage diameter stenosis). The optimal cut-off value of QFR was 0.765. Both univariate and multivariable regression analyses revealed that QFR >0.765, Qm ≤15 mL/min, and PI >3.0 independently contributed to early IMA failure.

There were statistically significant correlations between preoperative QFR of the LAD artery and intraoperative TTFM parameters (Qm, PI) of the IMA. Preoperative QFR and intraoperative Qm and PI exhibited excellent predictive value for early IMA failure.

This study aimed to evaluate the efficacy and safety of total coronary revascularization via left anterior thoracotomy (TCRAT) by comparing it to conventional coronary artery bypass grafting (CABG) with median sternotomy.

In this retrospective study, 108 patients (95 males, 13 females; mean age: 57.1±8.8; range, 41 to 75 years) who underwent TCRAT (Group 1) and 154 patients (126 males, 28 females; mean age: 61.2±9.8; range, 31 to 79) who underwent conventional CABG (Group 2) between February 1, 2021, and September 1, 2022, were evaluated. The operations were performed by the same surgical team. Preoperative, operative, and postoperative data of patients and mid-term follow-up data were analyzed.

Mean cardiopulmonary bypass and cross-clamp times, respectively, were 167.70±68.93 and 77.03±38.18 min in Group 1 and 106.64±38.27 and 62.21±24.06 min in Group 2 (p<0.001). During the postoperative period, the all-cause mortality rate was 5.8% (n=9) in Group 2, while it was 0.9% (n=1) in Group 1; there was a statistically significant difference between the two groups (p=0.037). Nevertheless, the mean preoperative EuroSCORE (European System for Cardiac Operative Risk Evaluation) II was 2.59±2.3 in Group 2, which was significantly higher than the mean EuroSCORE II of Group 1 (1.37±1.5; p<0.001). The mean hospitalization duration for Group 2 was 6.99±3.37 days, and the mean hospitalization duration for Group 1 was 6.77±4.24 days. Duration of hospitalization was statistically significantly shorter in Group 1 (p=0.047). In addition, the mean perioperative number of erythrocyte suspension transfusions in Group 1 was 1.51±1.74, while it was 1.86±1.75 in Group 2. Significantly fewer erythrocyte suspension transfusions were performed in Group 1 (p=0.033).

The findings of our study indicate that TCRAT is a safe and viable technique when performed on a select patient group compared to the conventional method.

To evaluate the long-term angiographic patency of saphenous vein grafts (SVG) harvested using the no-touch technique compared to the conventional technique.

This was a single-center, retrospective, cohort study. The inclusion criteria were individuals who underwent a CABG (coronary artery bypass grafting) between January 1995 and July 2020, and who successively needed a clinically-driven angiography. The primary endpoint was long-term patency. The secondary endpoints were differences in patency based on sub-group analysis (single vs. sequential graft, divided by target vessel).

The study included 1520 individuals (618 no-touch, 825 conventional and 77 arterial grafts). The mean clinical follow-up time was 8.4 years ± 5.5 years. The patency per patient was 70.7% in the no-touch grafts vs. 46.7% in the conventional grafts (p < 0.001, OR = 2.8). The graft patency was 75.9% in the no-touch grafts vs. 62.8% in the conventional grafts (p < 0.001, OR = 1.8).

The no-touch vein grafts were associated with statistically significantly higher patency at long-term compared to the conventional grafts.

Diffuse idiopathic skeletal hyperostosis (DISH) is a common disorder characterized by ossification of tendons and ligaments. DISH has been largely associated with an increased risk of metabolic syndrome and type 2 diabetes. The objective of the present study is to investigate the role of DISH in the risk of coronary artery disease (CAD).

We conducted an observational cross-sectional study of patients without a history of rheumatic musculoskeletal diseases who underwent coronary angiography between March 2016 and April 2021. The SYNergy between percutaneous coronary intervention with TAXus and cardiac surgery (SYNTAX) score was calculated based on coronary angiography images. DISH diagnosis was based on standard X-ray images and computed tomography scans (Resnick criteria). Demographic and clinical characteristics were retrieved from electronic medical records. Multinomial and binary logistic regression models were employed to determine the association between SYNTAX score (dependent variable) and DISH (independent variable).

The study included 187 patients, 82.9% of whom were men, with valid radiological imaging. 83 (44.4%) patients had a confirmed radiological diagnosis of DISH. Diagnosis of DISH was associated with a higher SYNTAX score [adjusted odds ratio (aOR) 34.1, 95% confidence interval (CI) 1.41-79.2 p=0.049], independently from traditional cardiovascular risk factors. In patients aged <70 years, DISH was associated with a 7-fold higher risk of belonging to the highest category of SYNTAX (≥34), compared to non-DISH (aOR 7.23, 95% CI 1.08-48.4; p=0.041). The extension of vertebral calcification was significantly associated with SYNTAX score (r2 0.378, p<0.0001).

DISH diagnosis is common in patients at high risk of cardiovascular disease or with definitive CAD. DISH was independently associated with higher CAD complexity.

All cardiologists should delve into history to understand the current state of the art of their specialty. In the last century, the coronary stent was a pivotal achievement of research and biotechnological engineering. Since then, technology has advanced, and substantial improvements have been incorporated into this device, which has become the gold standard for treating coronary artery disease. This article summarizes the history of the coronary stent from its inception to the present day. The document reviews key historical and scientific milestones that have contributed to making percutaneous angioplasty a safe and highly effective procedure due to coronary stents. The evolution of the stent has been closely linked to the growth and maturation of interventional cardiology to date.
