Abstract

Background: The aim of the study was to evaluate the incidence of Coronary artery disease (CAD) and predictors of CAD in patients with severe AS in western Rajasthan population.

Methods: Data from all consecutive patients with severe AS undergoing AVR at a major tertiary cardiac and vascular center in Udaipur were entered in a prospective registry beginning in 2015. Significant CAD was defined as one or more major coronary arteries having an estimated narrowing of ≥70% and left main coronary arteries having an estimated narrowing of ≥50% on coronary angiography. We excluded patients with multiple valve disease, significant aortic regurgitation, or prior CAD or valve surgery.

Results: Mean age of 55 enrolled patients was 52.64±15.5 years. Diabetes mellitus and hypertension were present in 3.64% and 5.45% of patients, respectively. Moderate and severe Left ventricular ejection fraction (LVEF) was found in 16.36% and 10.91% patients, respectively. Only 5.45% patient had severe CAD and thus underwent AVR and coronary artery bypass grafting, and rest 94.55% patients underwent AVR. Mean age of patients who underwent AVR was 51.75±15.36 years and who underwent AVR and CABG was 68±11.14 years with no significant association (p=0.078). Proportion of patients requiring AVR and CABG was significantly higher in moderate (22.22%) and severe LVEF (16.67%) as compared to normal or mild (p=0.034).

Conclusions: Coronary angiography before AVR will be considered in patients with multiple risk factors for cardiovascular disease or in patients above 68 years of age without risk factors for cardiovascular disease. However, larger studies on heterogeneous population are required to prove our findings.
