CLINICAL FEATURES OF PATIENTS WITH CORONARY ARTERY ECTASIA COMPARED WITH STENOTIC CORONARY ARTERY DISEASE

Objective: To study the prevalence of coronary artery ectasia in the population of patients referred for coronary angiography. To describe clinical characteristics of patients with coronary artery ectasia, analyzing presentation and cardiovascular risk. To compare clinical and angiographic variables in patients with and without coronary artery ectasia. Study Design: Descriptive cross sectional study. Place and Duration of Study: Adult cardiology department in Armed Forces Institute of Cardiology/NIHD, Rawalpindi, 6 months duration after approval of synopsis i.e. Oct 2018 to May 2019. Methodology: After meeting the inclusion criteria 300 patients were enrolled. Patients admitted in AFIC/NIHD with chest pain, ST-elevation MI, Non-ST-elevation myocardial infarction and unstable angina were enrolled. Coronary angiogram was done by cardiologist. Two distinct cardiologists or resident cardiologists reported the angiograms including the coronary artery anatomy and the presence of ectatic segments or any stenotic lesions in each vessel. All the collected data was entered and analyzed on SPSS version 23. Results: The mean patients was 58.23 ± 11.73 years. The male to female ratio was 14:1. Coronary artery ectasia was detected in 53 (17.7%) patients of coronary angiography. Stenotic coronary artery disease was detected more commonly in patients having factors like diabetes, hypertension, and dyslipidemia but specifically among smokers, ectatic segments were detected higher. Conclusion: Compared to coronary artery disease, coronary ectasia occurred more in smokers and less in diabetes.
