ABSTRACT

Objective: To determine the frequency of left main coronary artery disease in patients presenting with acute coronary syndrome having ST elevation in lead avR.

Study Design: Descriptive/ cross sectional study

Place and Duration of Study: This study was conducted at the Department of Cardiology, Liaquat National hospital, Karachi from March 2019 to September 2019.

Materials and Methods: Total 246 patients presented with acute coronary syndrome had ST elevation in lead avR > 0.5 mm on ECG were included. Demographic data were recorded. All patients underwent coronary angiography to diagnose coronary artery disease. SPSS version-21 was used. Descriptive statistics were calculated. Stratification was done and chi square test was applied. P-value ≤0.05 was taken as significance.

Results: There were 174 male and 72 female patients. The mean duration of chest pain was 45.01±14.40 minutes. 42.3% were diabetic, 58.9% were hypertensive, 37.8% were smokers, and 42.3% were obese. The left main stem disease was observed in 201(81.7%) patients and its significant association was observed with smoking and obesity with p<0.05.

Conclusion: The ST-segment elevation on lead aVR was an important predictor of occurrence of left main disease in patients with ACS.
