Relation of angina pectoris to coronary artery disease in aortic valve stenosis.

Overview

One hundred three patients with isolated, severe aortic stenosis (AS) were retrospectively analyzed to determine the relation of angina pectoris to angiographically significant coronary artery disease (CAD). All patients underwent coronary angiography regardless of the presence or absence of angina. Angina was significantly associated with CAD (p less than 0.002), with a sensitivity of 78% and a specificity of 53%. However, 25% of the patients without angina had angiographically significant CAD, and in these patients there was a 70% prevalence of 1-vessel disease. Patients with isolated, severe AS should undergo coronary angiography to identify coexistent CAD accurately. The absence of angina does not reliably exclude angiographically significant CAD.
