摘  要:目的探讨冠心病患者舒张早期二尖瓣血流速度/二尖瓣环运动速度(E/E’)比值与左室舒张末压(LV-EDP)的相关性。方法30例冠心病患者在接受心导管检查之前24 h内进行经胸多普勒超声心动图检查;常规测取二尖瓣血流参数、二尖瓣环运动参数。LVEDP由6F猪尾导管测取。结果线性回归分析表明,舒张早期E/E’比值与LVEDP有较好的相关性(间隔部r=0.739,P<0.01;左侧壁r=0.710,P<0.01)。间隔部E/E’≥10估计LVEDP≥15 mmHg的敏感性为85%、特异性为89%;左侧壁E/E’≥10估计LVEDP≥15 mmHg的敏感性为82%、特异性为90%。结论舒张早期E/E’比值与LVEDP有良好的相关性,是半定量估计LVEDP的有效指标。Objective To assess the ratio of mitral velocity to early diastolic velocity of the mitral annulus(E/E') with coronary disease associated with left ventricular end-diastolic pressure(LVEDP).Methods Thirty consecutive patients with coronary disease underwent transthoracic Doppler echocardiography within 24 hours before cardiac catheterization.Doppler signals from the mitral inflow,TDI of the mitral annulus were obtained.LVEDP was obtained with pig-tailed catheters.Results Linear regression analysis showed E/E' had the better correlation with LVEDP(S:r=0.739,P〈0.01;L:r=0.710,P〈0.01).In septal area,E/E'≥10 predicted LVEDP≥15 mmHg with a sensitivity of 85%,a specificity of 89%,in lateral wall E/E'≥10 predicted LVEDP≥15 mmHg with a sensitivity of 82%,a specificity of 89%.Conclusions E/E' provides valuable parameters for estimating of LVEDP,and may provide a semi-quantitative index for predicting LVEDP(15 mmHg) elevation.
