Prevalence of coronary artery disease in patient with valvular heart disease.

The prevalence of coronary artery disease in valvular disease was 10.9 per cent. The prevalence of coronary artery disease was more common in males, increasing age, aortic valvular disease and mitral regurgitation with chest pain, other types of valvular lesions did not correlate with the presence of coronary artery disease. The prevalence of significant coronary artery disease especially three vessel disease was relatively rare in those aged < 50 years. We recommend performing coronary arteriography only in patients aged > 50 years regardless of symptoms of chest pain, especially in aortic valvular disease and mitral regurgitation.
