title: [Heart function in patients with and without wall dyskinesia. Echocardiographic-cineangiographic comparative study].
abstract: The mean velocity of circumferential fibre shortening determined by echo and angiography is a good parameter for the assessment of the basal left ventricular contractility. It remains relatively constant in acute and chronic changes in preload i.e. compensated volume overload, though the inverse relation to afterload is still maintained. For the calculation of mean VCF we assumed the heart to be a rotational ellipsoid. Models and extrapolation of curve are not necessary for the calculation of this parameter. On the basis of these considerations we investigated with the echographic and angiographic technique 5 patient groups having normal cardiac function (group I, IV) and abnormal function (group II, III and V).
