[Functional state of the myocardium in hypertension (an echocardiographic study)].
The functional condition of the left ventricle was studied in 96 patients with I--II stage hypertensive disease by means of echocardiography according to the value of the ejection fraction, tension of the left-ventricular wall and mean rate of circular shortening of the myocardial fibers. It was found that in hypertensive disease tension of the left-ventricular wall increased to a lesser degree than the indices of external work, which was considered to be a manifestation of preserved contractile reserve of the heart muscle. The ejection fraction and the rate of myocardial fiber shortening did not depend on the stage of the disease, did not change under the effect of treatment and were within normal limits. It is concluded that the functional condition of the left-ventricular myocardium does not change in I--II stage of hypertensive disease.
