Abstract:
A prospective study on a group of 129 patient was echocardiographical compared with a group of 109 normal subjects: based on Framingham criteria, the prevalence of LV hypertrophy were 88.4%, LV dilatation - 58.9% and systolic dysfunction - 21.7%. To determine the influence of haemodyalysis on echo-Doppler indices of the heart, 58 patients were studied by Doppler-echocardiography immediately before and after haemodialysis. This procedure resulted in immediate alterations of the heart: decrease in blood pressure, increase in heart rate. Left ventricular diameters and volumes decreased significantly whereas, the systolic function, cardiac output and index increased. Haemodialysis elicited marked changes in the left ventricular filling pattern: mitral peak E, peak A, ratio E/A decreased and pulmonary vein flow S/D ratio increased. The results provide evidence for the pronounced preload-dependence of morphologic, functional and hemodinamic indices of the heart.
