[Echocardiographic changes in patients with polycystic nephropathy].

We have studied with the echocardiography M-Mode, 2-D, Doppler three groups of 15 subjects for testing the presence of cardiac abnormalities probably related to primary collagen defect in patients with autosomal dominant polycystic kidney disease (ADPKD) The first group was made up of patients with ADPKD and normal renal function, the second of patients with ADPKD in hemodialysis (HD), the last one of patients in HD for other renal disease. In the first group we found no cardiovascular abnormalities while we found an increased incidence of valvular disease (p = 0.016) in patients with ADPKD in HD and an increased incidence in valvular disease (p = 0.016) and left atrial dilatation (p = 0.006) in patients in HD for different renal disease. When we estimated the cases on the ground of dialytic age uncorrelated with the initial renal disease, only the incidence of valvular calcifications was increased in patients on HD more than 3 years (p = 0.034). In our group of patients the echocardiographic abnormalities seem to be related more to uremic cardiomyopathy even if we cannot deny the existence of primary cardiac disease in patients with ADPKD.
