Author contributions: Du CS and Hao BC designed the research study; Mao S and Yin Z collected and organized the clinical data; Xia HH and Zhao B performed the statistical analysis and interpreted the results; all authors reviewed and approved the final version of the manuscript. Du CS and Hao BC drafted the manuscript, and contributed equally to this work as co-first authors. We have designated both Author Zhao B and Xia HH as co-corresponding authors because they contributed equally but in different capacities to the success of the study. Specifically, Xia HH was responsible for the study concept, protocol design, and supervision of data analysis. Zhao B oversaw patient recruitment, data collection, and played a leading role in manuscript drafting and revision. Both authors have full access to the data and agree to take joint responsibility for the integrity of the work. Given their complementary roles and equal contributions, we believe it is appropriate to list them as co-corresponding authors.

Abstract
BACKGROUND

Post-procedural psychological disorders are frequently overlooked in elderly patients undergoing percutaneous coronary intervention (PCI), despite their potential impact on long-term cardiovascular outcomes.

AIM

To evaluate the incidence and prognostic significance of post-PCI psychological disorders in elderly patients with heart failure, and to examine their association with medication adherence and major adverse cardiovascular events (MACE).

METHODS

This retrospective cohort study included 330 consecutive patients aged ≥ 60 years with heart failure who underwent PCI between 2018 and 2021 at a single center, excluding those with prior psychiatric diagnoses. Psychological status within six months post-discharge was assessed using validated Chinese versions of the 9-item Patient Health Questionnaire and the 7-item Generalized Anxiety Disorder Scale, and medication adherence was measured by the 8-item Morisky Medication Adherence Scale (MMAS-8) scale. A subset of 145 patients with ≥ 24 months of follow-up were analyzed for MACEs. Multivariate logistic regression and Kaplan-Meier survival analyses were performed.

RESULTS

Post-PCI psychological disorders were identified in 40% of patients, with anxiety (36%), depression (32%), and comorbid symptoms (22%) being most prevalent. Affected patients had lower MMAS-8 scores [median 5 (IQR 4-6) vs 6 (IQR 5-7), P = 0.002] and a higher rate of low adherence (51.5% vs 30.3%, P < 0.001). Among the 145 patients followed longitudinally, MACEs occurred in 17.9%, with 65.4% of events in those with psychological disorders. Psychological disorders (OR = 2.66, 95%CI: 1.11-6.41, P = 0.028) and low adherence (OR = 2.77, 95%CI: 1.17-6.56, P = 0.021) were independently associated with increased MACE risk. Kaplan-Meier analysis showed reduced MACE-free survival in patients with psychological disorders (HR = 2.68, 95%CI: 1.25-5.73; log-rank P = 0.008).

CONCLUSION

Post-PCI psychological disorders are common in elderly patients with heart failure and independently predict poorer adherence and worse cardiovascular outcomes. Routine psychological assessment and adherence interventions may improve prognosis in this vulnerable population.

Keywords: Psychological disorders; Percutaneous coronary intervention; Medication adherence; Major adverse cardiovascular events

Core Tip: This retrospective study highlights the high prevalence (40%) of psychological disorders within 6 months after percutaneous coronary intervention (PCI) in elderly heart failure patients. These disorders-particularly depression and anxiety-were significantly associated with poor medication adherence, as measured by the 8-item Morisky Medication Adherence Scale. Moreover, both psychological morbidity and low adherence independently predicted major adverse cardiovascular events during 2-year follow-up. The findings support routine psychological screening and adherence-focused interventions as essential components of post-PCI management in older adults to reduce long-term cardiovascular risk.
