Left ventricular diastolic function in essential hypertension and chronic pyelonephritis with hypertension

Parameters of diastolic filling of the heart were studied in different types of arterial hypertension. In patients with essential hypertension and chronic pyelonephritis with hypertension diastolic dysfunction of left ventricle was found. There was moderate negative correlation between degree of severity of diastolic dysfunction and blood pressure. No significant correlation was found between derangements of transmitral blood flow and degree of left ventricular hypertrophy. Considerable differences in structure of diastolic blood flow (mainly in velocity parameters of flow during left atrial systole) were noted between different types of hypertension. It was suggested that characteristics of trasmitral blood flow depended on genesis of hypertensive syndrome.
