title: [Curves of aortic and mitral flow recorded by Doppler echocardiography in patients with primary hypertension].
abstract: The systolic and diastolic left-ventricular myocardium function was assessed by Doppler echocardiography in patients with hypertension. The study was carried out on 40 patients (26 men and 14 women) aged 21-50 years (mean 45 years) with essential hypertension, stage II according to WHO classification. The control group comprised 20 healthy subjects aged 19-48 years (mean 43 years). In patients with hypertension, as compared to controls, the Doppler curve of aortic flow showed an increased maximal and mean velocity of flow, the ejection time was shortened, and the ejection time to acceleration time index was decreased. The Doppler curve of the mitral flow in the patients showed reduced maximal velocity of early diastolic flow, increased velocity of maximal end-diastolic flow, decreased fraction of rapid left-ventricular filling, and lower ration of maximal early diastolic to end-diastolic flow. Doppler echocardiography is a useful method for assessment of left-ventricular myocardium functions in hypertension.
