Even though percutaneous coronary intervention (PCI) improved the survival of patients with acute myocardial infarction, still multivessel coronary artery disease remains an important factor burdening prognosis and it is being associated with a worse prognosis compared to single-vessel disease (SVD).
To compare the clinical profile and outcomes after the primary PCI in young patients with SVD vs multivessel disease (MVD).
The retrospective cohort of patients were divided into two groups: SVD and MVD group. The study population consisted of both male and female young (≤ 45 years) patients presented with ST-elevation myocardial infarction (STEMI) at the National Institute of Cardiovascular Disease, Karachi, Pakistan and undergone primary PCI from 1st July 2017 to 31st March 2018. Pre and post-procedure management of the patients was as per the guidelines and institutional protocols.
A total of 571 patients with STEMI, ≤ 45 years were stratified into two groups by the number of vessels involved, 342 (59.9%) with SVD and 229 (40.1%) with MVD. The average age of these patients was 39.04 ± 4.86 years. A lower prevalence of hypertension and diabetes was observed in SVD as compare to MVD group (25.1% vs 38%, P < 0.01; 11.7% vs 27.5%, P < 0.001) respectively. While, smoking was more prevalent among the SVD group as compare to MVD group (36.3% vs 28.4%, P = 0.05). The high-C Lesion was observed in a significantly higher number of younger patients with MVD as compared to SVD group (48.8% vs 39.2%, P = 0.021). Post-procedure thrombolysis in myocardial infarction flow grade was found to be not associated with the number of diseased vessels with a P value of 0.426 and thrombolysis in myocardial infarction flow grade III was observed in 98% vs 96.5% of the patients is SVD vs MVD group.
The MVD comprised of around 40% of the young patients presented with STEMI. Also, this study shows that diabetes and hypertension have a certain role in the pathogenesis of multivessel diseases, therefore, preventive measures for diabetes and hypertension can be effective strategies in reducing the burden of premature STEMI.
Core tip: Premature coronary artery diseases are at rise. Multivessel disease (MVD) is associated with poor prognosis. MVD comprised of around 40.1% of the young patients with ST-elevation myocardial infarction. Prevalence of hypertension and diabetes was high in ST-elevation myocardial infarction patients with MVD. In-hospital outcomes of primary percutaneous coronary intervention were not different for patient with MVD.
