CAC was identified in 2003 as a cardiovascular disease risk factor and an independent predictor of mortality. Investigators have known since at least 1996 that CAC is from 2 to 5 times more extensive in people on hemodialysis than in people with coronary artery disease but not kidney disease, said Dr. Asci, a nephrologist at the Ege University School of Medicine in Izmir, Turkey.
