Assessment of the left ventricular diastolic function of patients with essential hypertension by pulsed-wave Doppler tissue imaging / 中国医师进修杂志

Objective To explore the value of Doppler tissue imaging(DTI) in assessing the left ventricular diastolic function of patients with essential hypertension.Methods Twenty healthy person(group A),35 essential hypertension(EH) patients with normal left ventrecular mass index(LVMI,group B) and 30 EH patients with left ventricular hypertrophy(LVH,group C) were included.The mitral annular velocity in early diastole(Ea) and late diastole(Aa) were detected by DTI,meanwhile the mitral inflow velocity E and A were detected.Results The E,E/A,Ea,Ea/Aa of group B and group C were lower than those of group A(P0.05).The Ea,Ea/Aa of group C were lower than those of group B(P

The clinical significance of the alteration of the internal diameter of left atrium in hypertension patients / 中国基层医药

Objective To investigate the clinical significance of the alteration of left atrium diameter in hypertension patients.Methods Among 85 hypertension patients,65 cases were selected from the patients of our hospital.20 healthy subjects were also included in our study.Ultrasonography imager was used to measure the internal diameter of left atrium(LAD),septal thickness(IVST),left ventricular posterior wall thickness(LVPWT),left ventricular ejection fraction(LVEF),left ventricular mass index(LVMI),E/A ratio and rest heart rate(RHR) for the analysis among them.Results LAD significantly enlarged in hypertension and normal LVMI patients compared with that of the control group(P
