Cardiac abnormalities develop during chronic renal failure. The prevalence of ischemic heart disease, cardiac failure, and left ventricular disorders is high among patients initiating end-stage renal disease (ESRD) therapy, and appears to be getting higher. Age, gender, race, diabetes, and possibly geographic location are predictive of the presence of several cardiac conditions. Cardiac morbidity after the initiation of ESRD therapy is high, and cardiac causes are the most common reported cause of death. Cardiac abnormalities present on starting dialysis contribute to this morbidity and mortality. In epidemiological studies, higher cardiac death rates have also been associated with dialysis rather than transplantation as mode of ESRD therapy, peritoneal rather than hemodialysis, lower dose of dialysis, and unmodified cellulose rather than modified cellulose/synthetic hemodialysis membranes.
