Clinical Characteristics and Short-Term Outcomes of Patients Presenting with Acute Myocardial Infarction having Multi-vessel disease - A Single Middle- eastern Tertiary-Care Center Experience

OBJECTIVE: Patients with multi-vessel coronary artery disease (MVD) compared to single-vessel coronary artery disease (CAD) have more comorbidities and poor in-hospital outcomes. We aim to analyze MVD-AMI patients regarding clinical data and short-term outcomes. METHODS: This is a retrospective analysis of the prospectively collected data registry, a single-center study reviewing the clinical details and hospital outcome measures of AMI patients referred to our center for early revascularization from 2016 to 2019. RESULT: Out of 3041 patients presented with AMI, 491 (16%) had MVD on coronary angiogram. MVD-AMI patients were older, had a higher prevalence of DM, HTN, and prior history of ischemic heart disease compared to the non- MVD -AMI group (p < 0.001 for all). However, they presented more with non-anterior myocardial infarction, showed higher rates of post-myocardial infarction LV dysfunction, and mortality (p < 0.001). Older MVD-AMI patients showed higher rates of in-hospital morbidities and mortality compared to younger ones (p < 0.001). MVD- AMI women and Middle Eastern patients were older and showed a higher prevalence of cardiovascular risk factors compared to MVD-AMI men and South Asian patient population respectively. There were no significant differences recorded among the different subgroups of MVD-AMI patients regarding the hospital outcome measures. CONCLUSION: Our study highlighted the clinical characters and poor outcomes of a high-risk group of MVD-AMI with different demographic backgrounds. Although age was a strong predictor for in-hospital poor outcomes, neither gender nor ethnicity affected the outcomes in them.
