Patients with echocardiographic aortic valve calcium or mitral annular calcium have an increased prevalence of moderate or severe coronary artery calcium diagnosed by cardiac computed tomography.

The association between aortic valve calcium (AVC) and mitral annular calcium (MAC), as diagnosed by two-dimensional echocardiography, was investigated in 138 patients (76 women and 62 men, mean age 64±8 years) seen in a private cardiology practice at the New York Medical College. Coronary artery calcium (CAC) scores were diagnosed by 64-multislice computed tomography. AVC was present in 25 of 57 patients (44%) with moderate or severe CAC (a CAC score of more than 100) and in 15 of 81 patients (19%) with no or mild CAC (a CAC score of 0 to 100), P<0.001. Moderate or severe AVC was present in nine of 57 patients (16%) with moderate or severe CAC, and in two of 81 patients (2%) with no or mild CAC, P<0.005. MAC was present in 18 of 57 patients (32%) with moderate or severe CAC, and in seven of 81 patients (9%) with no or mild CAC, P<0.001. Moderate or severe MAC was present in eight of 57 patients (14%) with moderate or severe CAC, and in two of 81 patients (2%) with no or mild CAC, P<0.001.
