摘要 目的探讨和肽素对急性心肌梗死早期的诊断意义。方法选取本院2016年2月-2017年2月接诊的疑似心肌梗死的患者45例作为研究组,选取同期健康体检的受检者45例作为对照组,抽取患者的静脉血检测和肽素和肌钙蛋白(cTnI),使用ROC曲线和AUC表示诊断性能,同时根据两种方法的阳性率计算灵敏度和特异性。结果研究组患者的和肽素和cTnI水平均明显高于对照组,差异具有统计学意义(P<0.05);和肽素ROC曲线下面积为0.900,标准误为0.035,差异具有统计学意义(P<0.05),95%CI:0.833-0.967。当和肽素水平超过0.519时,诊断急性心肌梗死的灵敏度为73.3%。特异性为50%。cTnI诊断急性心肌梗死的ROC曲线下面积为0.854。结论和肽素在急性心肌梗死的早期诊断中具有一定诊断价值,联合cTnI检查能够明显提高诊断准确率。
