Angina and coronary artery disease in patients with aortic valve disease.

The significance of angina pectoris in patients with aortic valve disease (AVD) and the need for coronary arteriography before valve replacement are controversial. The history of chest pain and coronary arteriographic findings were reviewed in 333 patients > or = forty years old, with AVD: 142 with aortic stenosis, 87 with mixed AVD and 104 with aortic regurgitation. The prevalence of coronary artery disease (CAD) was similar among different types of AVD. Angina pectoris was more frequent in patients with aortic stenosis (56%) and mixed AVD (53%) than in patients with aortic regurgitation (24%) (p < 0.0001). Similar results were found in patients with and without CAD. Twenty-six of 95 (27%) patients with CAD had no chest pain at all. The absence of any chest pain in CAD patients was more frequent in those > or = sixty years old than in those < sixty (p < 0.05). Thus, since a significant number of patients had CAD in the absence of any chest pain, the authors recommend coronary arteriography for all patients > or = forty years of age before aortic valve replacement.
