摘　　要：目的:探讨急性心肌梗死(AMI)急诊经皮冠状动脉介入术(PCI)治疗后心肌活动指数(Tei指数)对心力衰竭的预测价值。方法:78例初发AMI行急诊PCI的患者,根据Gensini评分分组,于术后第7天测定Tei指数,并与B型利钠肽(BNP)进行比较,平均随访6.9个月。结果:(1)多因素logistic回归分析显示,心力衰竭的危险因素有:开通病变血管时间>6h、年龄>45岁、Tei指数>0.48、女性、冠脉病变Gensini积分>80分;(2)Tei指数独立预测AMI患者发生慢性心力衰竭的价值:ROC曲线下面积(AUC)为0.624(95%CI:0.485～0.763,P=0.09),Tei指数(临界值)=0.488时其预测心力衰竭的敏感性为50%,特异性为76.4%。结论:Tei指数对预测AMI患者急诊PCI术后发生心力衰竭有一定临床价值。Objective：To evaluate the predictive value of myocardial performance index （Tel index） for heart failure in patients undergoing emergenct percutaneous coronary intervention （PCI） after acute myocardial infarction （AMI）. Methods： Seventy-eight consecutive in-patients with AMI undergoing emergent PCI were recruited and grouped according to Gensini scores. Tei index was measured after seven days of emergent PCI and compared with B-type natriuretic peptide. All patients with AMI were followed up （mean 6. 9 months）. Results： Multivariate logistic regression analysis showed that Gensini scores and the left ventrieular ejection fraction （LVEF） exerted significant influence on Tei index （R^2 = 0.66） and Tei index presented the largest AUC in their ROC curves 0. 624 （95% CI： 0. 485-0. 763, P = 0.09）. The sensitivity and specificity for predicting heart failure by Tei index at the cutoff point of 0. 488 were 50% and 76.4%, respectively. Conclusion.. There is clinically significant predictive value of Tel index for heart failure in patients undergoing emergent PCI after AMI.
