房间隔应变率显像对冠心病左室舒张功能的评价

Evaluation of left ventricular diastolic function by atrial septal strain rate imaging in patients with CAD

目的探讨房间隔应变率(SR)对评估冠心病左室舒张功能的价值。方法应用彩色多普勒超声检测54例冠心病患者左室舒张功能,并分为松驰性下降组(A)、假性正常化组(B)和限制性充盈组(C),检测其房间隔SR曲线的各期峰值速度并与正常组对照。结果除A组舒张晚期应变率(SRa)增加外,其余各组指标随舒张功能不全程度增加,SR值降低与正常组对照均有显著性差异。结论房间隔应变率显像(SRI)可用于评价冠心病左室舒张功能。

Objective To study the significance of the strain rate imaging（SRI）of atrial septttm in evaluating left ventricular（LV） diastolic function in patients with coronary artery disease（CAD）. Methods Twenty healthy adults and fifty-four patients with CAD were grouped as normal, abnormal relaxation, pseudonormal and restrictive. The peak velocity variables of atrial septal strain rate of each group were measured and observed. Results Markedly different strain rate was measured in the patients and the controls. Conclusion SRI may be taken as an evidance in assessing left ventricular diastolic function in patients with CAD.
