Value of evaluating diastolic function with the single-beat E/(e’ × s) obtained by dual doppler echocardiograph in coronary heart disease patients with preserved left ventricular systolic function

摘要

Objective To assess the value of E/(e’×s)in estimating left ventricular diastolic dysfunction in patients with coronary heart disease by dual Doppler echocardiograph.Methods Seventy-seven consecutive coronary heart disease patients with preserved systolic function underwent echocardiographic study were included.The E,e’and s were obtained by the dual Doppler echocardio-
