【摘要】 目的探讨心肌酶谱与血清肌钙蛋白I(c Tn I)联合检测对急性心肌梗死(AMI)早期诊断的价值,提高AMI诊断正确率。方法检测120例疑似AMI患者心肌酶谱及c Tn I,并以心电图检查为金标准,分析心肌酶谱、c Tn I单独检测与联合检测对AMI早期诊断的价值。结果心电图检出AMI 107例,非AMI 13例;心肌酶谱诊断AMI的灵敏度、特异度、阳性预测值、阴性预测值分别为85.05%、76.92%、96.81%、38.46%;c Tn I诊断AMI的灵敏度、特异度、阳性预测值、阴性预测值分别为89.72%、92.31%、98.97%、52.17%;二者联合检测阳性率为88.33%,高于单独检测诊断阳性率(78.33%,80.83%)。结论 c Tn I单独检测对AMI诊断价值优于心肌酶谱,但两者联合检测诊断准确度高于单独检测,可提高AMI早期诊断正确率。更多还原

【Abstract】 Objective To investigate the value of myocardial enzyme combined cardiac troponin I(c Tn I)detection in early diagnosis of acute myocardial infarction(AMI),improving AMI diagnostic accuracy. Methods Detected the myocardial enzymes and c Tn I of 120 cases with suspected AMI, and ECG as the gold standard. Analysis the value of myocardial enzymes, c Tn I individual detection and combined detection for the early diagnosis of AMI. Results 107 cases of AMI and non-AMI 13 cases were detected by ECG,the sensitivity of myocardial enzymes diagnosis of AMI,specificity, positive predictive value, negative predictive value were 85.05%, 76.92%, 96.81%, 38.46%. By contrast,and c Tn I were 89.72%,92.31%, 98.97%,52.17%,combined detection positive rate was 88.33%,it was higher than the individual detection(78.33%,80.83%). Conclusion c Tn I individual detection is better than myocardial enzymes,but combined detection diagnostic accuracy is much higher,and it can improve the accuracy of early diagnosis of AMI.更多还原
