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.
