title: [Changes in the left ventricular function in hemodialyzed patients. Role of Doppler echocardiography].
abstract: The aim of this study was to provide a further contribution to the study on the alterations of left ventricular diastolic function induced by dialysis, using simple indexes of diastolic function obtained with Doppler. The study is conduced in 15 patients with renal failure aged between 22 and 51 years old by means of echocardiography M-2D a pulsed Doppler analysis of the left ventricular refilling flow, evaluated before and after dialysis. By the results is risen up that the dLA has had a significant reduction (p = 0.032), the dSLV have undergone a reduction that is not being significant, while the dDLV has had a significant reduction (p = 0.029), shortening fraction is improved even if in a not significant manner. Also the Doppler indexes has had a behaviour homogeneous in the group of studied patients. Early ventricular refilling is reduced, as showed by the reduction of E, consequence of the reduction preload, while the diastolic late refilling has showed a little increment, expressed by the increase af the peak A. The variations of these indexes, even if not statistically significant, express an alteration of pattern diastolic Doppler caused by both the reduction of preload and the alteration of ventricular relaxation. Besides this alteration, to our notice, is not to consider expression of myocardial compromise in this group studied patients. It would be however useful enlargement of the study to greater number of patients with follow-up for better comprehension of this cardiopathy and makes a more individual treatment of these patients.
