【摘要】 用PWD检测214例二尖瓣口血流频谱流速面积分数之后,发现冠心病及高血压性心脏病患者的0.5、0.33面积分数和舒张早期加速面积(EAA)分数与正常相应年龄组相比,差异有高度显著性(P<0.001),EAA与0.33面积分数有高度相关性(r=0.8279,P<0.001).回归方程为:(?)=0.05419+1.6552x,正常务年龄组的EAA分数均大于0.21,而两种疾病患者的EAA均小于0.21,因此,EAA面积分数可作为评价左室舒张功能的新指标。更多还原

【Abstract】 Area fractions of mitral flow velocity were measured by PWD in 214 cases. In hypertensive heart disease and coronary heart disease, 0.5 area, 0.33 area agd early diastolic accelerate area (J5AA) are significantly different from those of normal cases (P<0.001). There is high correlation between EAA and 0.33 area (r = 0.8279,P<0.001). Regression equation is y = 0. 05419 + 1.6552X. EAA in normaal cases are more than 0.21. The results suggest that EAA fraction is a new criterion for evaluating left ventricular diastolic function.更多还原
