[Cardiac adaptation in hypertension].

As many as 75 patients with essential hypertension were examined by echocardiography and radiocardiography. The development of hypertrophy was accompanied by the rise of the diastolic dimensions of the left ventricle regardless of the type of the heart overload (by volume or pressure). As left ventricle hypertrophy developed, the myocardial contractility declined and normal hemodynamic function of the heart was maintained due to the Frank-Starling mechanism. The relationship has been established between the intensity of hypertrophy, left ventricle function and the hemodynamic profile of the disease.
