title: Echocardiographic evaluation in patients with autosomal dominant polycystic kidney disease and end-stage renal disease.
abstract: Cardiovascular abnormalities have been considered important extrarenal manifestations of autosomal dominant polycystic kidney disease (ADPKD). However, little is known about their prevalence in patients with ADPKD undergoing hemodialysis (HD). To investigate whether cardiac abnormalities are more prevalent in these patients, clinical and echocardiographic manifestations of cardiovascular disease were evaluated in a group of 32 patients with ADPKD and a matched control group of 32 patients without diabetes treated by chronic HD for more than 6 months. Predialysis systolic and diastolic blood pressure (BP), prevalence of hypertension, and number of patients requiring antihypertensive medications were lower in the ADPKD group than controls. There was no difference in the prevalence of cardiac events, including cardiac failure, ischemic heart disease, and arrhythmia. Systolic dysfunction, diastolic patterns, and left ventricular hypertrophy were similar in the two groups. In patients with ADPKD, simple regression analysis showed left ventricular mass (LVM) index was correlated with hemoglobin level and predialytic systolic and diastolic BPs. In multiple regression analysis, predialysis systolic BP was the only independent variable linked to LVM index. The prevalence of aortic, mitral, and tricuspid valve disease did not differ between groups. In conclusion, the occurrence of cardiovascular complications in patients with ADPKD is similar to that of HD patients with other primary renal diseases, although hypertension is less prevalent.
