[Echocardiographic indices of the pumping and contractile functions of the left ventricle and left ventricular cardiac insufficiency].
EchoC-indices for the left ventricle function and the degree of left ventricular insufficiency are confronted in 148 patients with various degree of left ventricular insufficiency determined by clinical and instrumental non-invasive examination, right and/or left heart catheterization and the method of dye dilution. It was established that in the differentiation of the initial left ventricular insufficiency, EchoC-indices of the pump and contractility function of the left ventricle have a diagnostic sensitivity of 94 per cent and give a relatively low false positive (12%) and false negative results (6%). EchoC-indices, which are with the highest diagnostic sensitivity in the determination of the initial left-ventricular insufficiency, are the telediastolic size and left ventricular volume; the fraction of shortening, average rate of contraction of the circumferential fibrils and the fraction of forcing out.
