BACKGROUND: Coronary angiography has been indicated in the preoperative phase for patients with valvopathy over 35 years of age. However, the actual prevalence of obstructive coronary artery disease (CAD) in this population has been little studied.
OBJECTIVE: To assess the prevalence of and the risk factors for CAD in candidates for valve surgery in Brazil.
METHODS: Coronary angiography was performed in 3,736 patients who were candidates for valve surgery; prevalence of and risk factors for CAD associated with valvopathy were assessed.
RESULTS: CAD was associated with valvopathy in 121 patients (prevalence of 3.42%). In 79 patients (68.1%), CAD was diagnosed by means of preoperative coronary angiography. Of these 79 patients, 50 (63.3%) had isolated aortic valvopathy or aortic valvopathy associated with mitral valvopathy. Smoking habit was observed in 54 patients (68.3%), hypertension in four (43%), family history in 24 (30.3%), diabetes mellitus in 15 (18.9%), and obesity in eight (10.1%). Of the 121 patients, 95.7% were over 50 years of age. Only five (4.3% of the patients with CAD) were below 50 years of age, and all of them had at least one risk factor for CAD.
CONCLUSION: CAD prevalence was low in the patients studied. Aortic valvopathy was the most frequent valvopathy associated with CAD, and most patients were over 50 years of age. The ideal age for routine preoperative coronary angiography in patients with valvopathy should be reassessed.
