Abstract
Objectives: The purpose of our study was to determine the frequency of
left main stem disease on coronary angiography in patients with non-ST
segment elevation myocardial infarction (NSTEMI). By studying the exact
frequency of the left main stem (LMS) disease in NSTEMI patients in our
population, we will be able to better risk stratify and plan further
management for this group of patients.
Methodology: This cross-sectional study was conducted at the
Department of Cardiology, Chaudhry Pervez Elahi Institute of Cardiology
(CPEIC), Multan from 14-June-2017 to 13-Dec-2017. Total 248 patients
with NSTEMI were included in the study. Coronary angiography was done
in all selected patients. Diagnosis of LMS disease was made when
stenosis in the LMS artery was more than half of the diameter of the left
main coronary artery.
Results: There were 80.6% male and 19.4% female patients with a mean
age 49.39±7.23 years. In this study, 37.1% patients were found with left
main stem disease. Among LMS disease patients, there was 82.6% male
and 17.4% female patients. 55.4% of patients were aged 50 years and
above. 40.2% were smokers and 33.7% were diabetic. No significant
association of LMS was found with the age group (p=0.66), gender
(p=0.54), smoking status (p=0.54) and diabetes mellitus (p=0.95).
Conclusion: In this study, we found a high frequency of LMS disease in
our population. This subset of patients with NSTEMI requires early revascularization. This also signifies a need to re-evaluate our screening
programs and management protocols related to coronary artery disease.
