Prevalence and Predictors of Coronary Artery Disease in Severe Aortic Stenosis Patients Undergoing Surgery

BACKGROUND present study is to find out the prevalence of CAD in severe Aortic Stenosis (AS) patients undergoing aortic valve and the relation between the conventional risk factors and CAD in them. Calcific aortic stenosis is associated with same risk factors as coronary artery disease. Studies on calcific aortic stenosis and CAD are rarely reported from India. aim of the study is to find out the predictive value of angina for presence of CAD in severe aortic stenosis. AND METHODS cases of isolated severe aortic stenosis undergoing CAG before aortic valve replacement were included in the study. Data various risk factors, symptoms, echocardiographic parameters and angiographic profile were collected. a total of 94 patients who have undergone aortic valve replacement for severe AS 40 (42.6%) had CAD. Risk factors advanced age, hypertension, diabetes and smoking were more in patients with CAD compared to isolate AS. Mean was more in the AS + CAD group compared with AS group. Presence of angina had a sensitivity of 82.5% and of 51.85% for predicting coexisting CAD. severe aortic stenosis, patients undergoing AVR 42.6% of patients had significant obstructive CAD. The conventional factors predict presence of coronary artery disease. Angina has got a fairly good sensitivity, but moderate specificity for .
