[Comparative analysis of the parameters of left ventricular systolic and diastolic functions in patients with hypertension and patients with hypertrophic cardiomyopathy].

17 patients with essential hypertension and asymmetric, 12 ones with concentric left ventricular (LV) hypertrophy and 13 patients with asymmetric hypertrophic cardiomyopathy (HCM) were examined by M-mode and Doppler echocardiography. There were significant changes of LV diastolic volumes, mitral flow velocities and phase duration in all groups of patients compared to healthy subjects. Nevertheless, the hypertensive groups had noninvolved LV systolic function. The HCM group had impaired LV systolic function because of a decline in pump capacity of hypertrophic myocardium resultant from diminution of its cavity.
