The Number of Cases of Left Main Coronary Artery Disease Detected During Angiography

Objective: The study aimed to evaluate the occurrence and pattern of left main stem (LMS) stenosis in patients undergoing coronary angiography in a tertiary care setting. Methodology: A retrospective study was conducted in the Cardiology Department of Imran Idrees Teaching Hospital, Sialkot. After obtaining ethical and departmental approvals, data collection occurred from February to April 2024. The study involved 126 patients of both genders who underwent coronary angiography. Data was analyzed using SPSS version 25, and findings were presented in tabular format. Results: The average age of the patients was 65 ± 18.44 years. Among the participants, 57 (45.2%) were male and 69 (54.7%) were female. The age of most of the patients (44.8%) ranged from 51–60-year. Most patients had both hypertension and diabetes mellitus (84.8%), while 8.8% had only hypertension and 4% had only diabetes mellitus. LMS stenosis was identified in 9 patients (7.2%). Of these, 5 patients (55.5%) had ostial LMS, and 4 patients (44.5%) had distal LMS. Conclusion: The findings indicate a moderate frequency of left main stem disease among the patients, with ostial lesions being the most common type of LMS detected.
