Prevalence of valve calcium and association of valve calcium with coronary artery disease, atherosclerotic vascular disease, and all-cause mortality in 137 patients undergoing hemodialysis for chronic renal failure.

Of 137 patients (mean age 63 years) who underwent hemodialysis for chronic renal failure, 65 (47%) had mitral valve calcium, mitral annular calcium, or aortic valve calcium. Thirty-eight of 65 patients (59%) who had valve calcium died at 3.5-year follow-up versus 21 of 72 patients (29%) who did not have valve calcium and who died at 4.3-year follow-up (p = 0.0005).
