Abstract:
Forty-eight patients with essential hypertension or coronary disease in cardiac function NYHA class I underwent a routine electrocardiography and a cotour Dopper echocardiography were studied,and by multiple stepwise regression analysis irwas found that significant partial correlations exist between PTFVl and left atrial dimensionas wee as E peak,Macruz index and A peak.Macruz index≥1.6 gave a sensitivity of 71%VS accuracy 64% for A peak increase(>70 cm/s),of 61% vs 58% for A/E>1 respectively,.These results suggest that electrocardiographlic indexes of abnormality of left atriun combined with Colour Doppler echocardiograpby may be more helpful to predict wkether the latent left ventricutar diastolic dysfunction or decrease of diastolic reserve was present or absent in patients with essential hypertension or coronary artery disease in normal clinical cardiac function.
