目的探讨Tei指数评价急性心肌梗死患者支架植入术前后心脏功能改变的价值。方法选择61例急性心肌梗死患者术前、术后一月及术后半年行超声心动图,测量LVDs,LVDd,左心室射血分数(LVEF);二尖瓣血流频谱E峰、A峰及E/A;Tei指数。结果患者术后1个月及半年时Tei指数较术前均显著下降(P<0.05,P<0.01),LEVF较术前均显著升高(P<0.05,P<0.05);患者术后半年时LVEDd和LVEDs较术前显著下降(P<0.05,P<0.05)。结论 Tei指数能简便、敏感、综合评价心脏的整体收缩舒张功能。
Objective To investigate the value of Tei index in the evaluation of cardiac function in patients with acute myocardial infarction before and after stent implantation. Methods Sixty-one patients with acute myocardial infarction underwent echocardiography before operation, one month after operation and six months after operation. The LVDs, LVDd and left ventricular ejection fraction (LVEF) were measured. The peak E, peak A and E / A; Tei index. Results The Tei index decreased significantly at 1 month and 6 months after operation (P <0.05, P <0.01), and LEVF was significantly higher than that before operation (P <0.05, P <0.05) LVEDd and LVEDs were significantly lower than those before operation (P <0.05, P <0.05). Conclusion Tei index can be simple, sensitive and comprehensive evaluation of the overall systolic and diastolic heart function.
