Congestive heart failure in dialysis patients.
To determine the prevalence of congestive heart failure in dialysis patients and the disorders with which it is associated, 85% of 153 nondiabetic patients who were undergoing maintenance dialysis had echocardiography and gated cardiac scan. Ten percent (n = 15) had congestive heart failure, 53% (n = 8) of whom had dilated cardiomyopathy, and 47% (n = 7) had hypertrophic hyperkinetic cardiomyopathy. Ischemic heart disease was an additional independent risk factor for congestive heart failure. Significantly more of those patients with dilated cardiomyopathy were smokers and none were hypertensive, whereas all those patients with hypertrophic cardiomyopathy were hypertensive. The prevalence of hypertrophic hyperkinetic disease was 11%, of dilated cardiomyopathy 18%, and of symptomatic ischemic heart disease 18%. We concluded that congestive heart failure in dialysis patients is associated not only with dilated cardiomyopathy but also with hypertrophic cardiomyopathy, a disease that requires echocardiography for diagnosis and that has different risk factors and management.
