Correlation between Diastolic Function and Mass and Geometryof Left Ventricle in Essential Hypertension

Object Diastolic function’ s assessment is vital in order to produce information relevant to patients’ functional class, management and prognosis. We sought to investigate diastolic dysfunction in essential hypertension (EH) with or without coronary heart disease (CAD) using color M - mode Doppler echocardiography and to study the relation between diastolic dysfunction and left ventricular mass index (LVMI) and geometry of LV, and to demonstrate partly the cause of increased cardiovascular risk of an echocardiographic pattern of LV geometry. Methods 36 normal subjects (Group Ⅰ) and 107 patients with essential hypertension (Group Ⅱ) were studied using color M-mode Doppler echocardiography. Four different LV anatomic adaptation to hypertension were i-dentified by categorizing patients according to values of end-diastolic relative wall thickness (RWT) and LVMI. We measured the rate of propagation of peak early filling flow velocity (Vp), time delay (TD) of the peak early filling flow velocity from mitral
