Abstract:
Objective To study the changes of diastolic function of left ventricle by tissue Doppler imaging (TDI) and the serum level of endocrine factors,and analyse the relations between these factors and mass or diastolic function of left ventricle in patients with essential hypertension.Methods Sixty one patients with essential hypertension were divided into left ventricular hypertrophy(LVH) group and no left ventricular hypertrophy(NLVH) group.Twenty healthy subjects were considered as control group.The early(e) and late(a) diastolic maximal myocardial velocity and e/a of lateral wall motion of mitral valve annulus were recorded by TDI.The levels of atrial natritic peptide(ANP),brain natriuretic peptide(BNP),endothelium(ET),calcitonic gene related peptide(CGRP) and insulin like growth factor 1(IGF 1) were measured by radio immunology analysis.Results The e wave maximal velocity in LVH group was lower than that of NLVH group and control group [( 14.56 ? 7.83 ) cm/s,( 16.40 ? 0.66 ) cm/s,( 18.68 ? 3.78 ) cm/s,respectively],and a wave maximal velocity in LVH group was higher than that of NLVH group and control group [( 18.28 ? 9.60 ) cm/s,( 16.03 ? 5.88 ) cm/s ,( 14.53 ? 1.28 ) cm/s,respectively]; The e and a maximal velocity velocities in both LVH and NLVH groups had statistic differences with those of control group(P
