Cardiac Pathology in Patients with End-Stage Renal Disease Maintained on Hemodialysis

We report the spectrum of cardiovascular pathology found on autopsy examination in 106 consecutive patients with end-stage renal disease. Cardiovascular pathology was present in nearly all patients, and was the most frequent cause of death (36%), with acute myocardial infarction accounting for 15%. Particularly frequent pathologic findings were left ventricular hypertrophy, coronary and aortic atherosclerosis, pericarditis with effusion, myocardial fibrosis, and valvular dilatation. Cardiovascular death rate was higher during the first year than after the fifth year of dialysis. Nearly all patients had a history of hypertension. The nature of the underlying cause of renal failure and pre-existing cardiovascular disease, specifically diabetes mellitus and hypertension, were the principal predictors of cardiovascular mortality rather than maintenance hemodialysis therapy per se.
