Evaluation of Left Ventricular Function in Hypertensive Patients by Doppler Echcardigraphy

Objective To evaluate the left ventricular function in hypertensive patients by Doppler echocardiography.Methods Fifty hypertension patients and thirty normal subjects underwent Doppler echocardiography to find out the following items:left atrial diameter(LAD),diastolic interventricular septal thickness(IVST),left ventricular posterior wall thickness(PWT),mitral valve anterior leaf EF slope(MV-EF),moving amplitude of interventricular septal and left ventricular posterior wall,left ventricular ejection fraction(LVEF),left ventricular fractional shortening(FS),stroke volume(SV),early filling velocity of the E wave(VE),peak A wave velocity(VA),mitral valve peak flow velocity E/A ratio and isovolumic relaxation time(IVRT).Results The parameters of left ventricular structure(LAD、IVST、PWT)were significantly higher in hypertensive patients than those in normal subjects(P0.0 1).Left ventricular systolic functions(EF,FS)and(SV)were significantly higher in hypertensive patients 1 than those in normal subjects(P0.05).The left ventricular diastolic function of hypertensive patients became abnorm al,and the variability was clear compared with normal subjects(P0.01).Conclusions Doppler echocardiography can indicate the left ventricular structural and functional changes of hypertensive patients and provide objective data to clinical diagnosis and treatm ent.
