室壁运动指数估测急性心肌梗死预后的探讨

The study of wall motion index to evaluate prognosis of AMI

目的 :探讨室壁运动指数对急性心肌梗死的预测价值 ;方法 :对 6 2例急性心肌梗死患者于 1周内行二维超声心动图检查 ,进行室壁运动评分 ,计算得分指数。按室壁运动指数高低分成两组 ,A组 (指数≥ 1 4 )和B组 (指数 <1 4 ) ;结果 :A组 6 2 4个室壁节段中有 2 0 2个节段室壁运动异常 ,其中运动减低节段 89个 ,无运动节段 1 0 9个 ,矛盾运动 4个。B组 3 6 8个室壁节段中有 87个节段室壁运动异常 ,运动减低节段 3 9个 ,无运动节段 4 8个。A组与B组相比 :前者合并心力衰竭、心律失常比后者高 ,有显著差异 (P <0 0 5) ;结论 :室壁运动指数是评估急性心肌梗死早期预后的简单方法 ,能较好地预测急性心肌梗死早期的并发症和死亡的发生 ,值得临床推广应用。

Objective: To investigate the evaluation of wall motion indexes; Method: this study was abuot 2DE examinations for the 62 cases, they were one week after their first acute myocardial infarction (AMI) attack. Observate their wall motion and determine the index results. According to high and low result, wall motion index would be divided into two groups: Group A (index≥1 4) and Group B(index<1 4);Result: group A 202 of 624 segments were dyssynergic (89 hypokinetic, 109 akinetic, 4 parakinetic). Group B 87 of 368 segments were dyssynergic (39 hypokinetic, 48 akinetic). To compare group A with group B. The former were combine with heart failure and severe arrhythmia than the later((P<0 05);Conclusion: So wall motion index was the simple method to evaluated early prognosis of AMI. We think wall motion index could be put into clinical practise. [
