Title: Assessment of left ventricular diastolic function in essential hypertension patients by Doppler echocardiography
Abstract: Objective To assess left ventricular diastolic function in the patients with essential hypertension by Doppler echocardiography.Methods 60 normotensives,61 hypertensives without hypertrophy(NLVH) and 57 with hypertrophy(LVH) (LVMI,left ventricular mass index124g/m 2 in males and 110g/m 2 in females) underwent 2DE and Doppler echocardiography.Results The ratio of early to late peak velocity(E/A) was 1 21±0 25 in normotensives and 0 96±0 20 in NLVH patients(P0 01);reversed pulmonary venous flow at atrial systole wave PA was(31 70±7 7) vs(38 9±5 8)cm/s(P0 01) in normotensives and in NLVH patients respectively.The isovolumic relaxation time(IRT) and left atrial dimension(LAD) had significant differences in three groups(P0 05~0 01).EF value was similar between normotensives and NLVH patients,but it was lower in LVH patients(P0 01).Conclusions E/A ratio,PA wave,Pai,IRT,C index and LAD are sensitive parameters indicating mild diastolic left ventricular dysfunction.Systolic left ventricular function has no change in NLVH patients.Spectral Doppler echocardiography is a practical and reliable technique in the noninvasive assessment of the left ventricular diastolic dysfunction in patients with essential hypertension.
