Key result
Among patients presenting for the first time with ST-elevation myocardial infarction, 42% had significant non-infarct related multivessel coronary artery disease.
Why the study?
The frequency of significant non-infarct related multi-vessel CAD in patients after their first presentation with STEMI needed to be determined.
Cross-Sectional (n=100)
No
A significant proportion (42%) of patients presenting with their first STEMI have concurrent non-infarct related multivessel coronary artery disease, highlighting a high burden of diffuse atherosclerosis.
Objective: To determine the frequency of significant non-infarct related multi-vessel coronary artery disease in patients after the first presentation with ST-elevation myocardial infarction. Methodology: A minimum of 100 consecutive patients from the department of cardiology, Mayo Hospital Lahore, who fulfilled the inclusion/exclusion criteria were selected. Percentage stenosis in non-IRA was calculated by using quantitative coronary analysis (QCA) software. Results: A total of 100 patients were enrolled in this study. There were 73(73.0%) males and 27(27.0%) females. The mean age of patients was 47.6±19.2 years. Out of 100 patients with STEMI, 42(42.0%) had non-IRA. Among non-IRA, 24(57.1%) had double vessel CAD and 18(42.9%) had triple vessel CAD. Conclusion: Significant non-infarct related multivessel coronary artery disease was common among patients after the first presentation with ST-elevation myocardial infarction.

Khan et al. (2022) conducted a cross-sectional in ST-elevation myocardial infarction (n=100). ST-elevation myocardial infarction was evaluated on Frequency of significant non-infarct related multi-vessel coronary artery disease (non-IRA). Among patients presenting for the first time with ST-elevation myocardial infarction, 42% had significant non-infarct related multivessel coronary artery disease.
