摘要 目的探讨急性心肌梗死(AMI)患者血清高敏心肌肌钙蛋白T(hs-cTnT)水平变化及其诊断意义。方法选取72例AMI患者,同时选取不稳定型心绞痛(UA)患者42例,稳定型心绞痛(SA)患者39例,检测各患者血清hs-cTnT、肌钙蛋白I(cTnI)和肌酸激酶同工酶(CK-MB)的水平。结果 AMI组患者血清hs-cTnT、cTnI和CKMB明显高于UA组和SA组(P<0.05);UA组和SA组血清hs-cTnT、cTnI和CK-MB比较差异无统计学意义(P>0.05);hs-cTnT、cTnI和CK-MB诊断AMI的ROC曲线下面积分别为0.882(95%CI为0.826~0.937)、0.816(95%CI为0.737~0.896)和0.680(95%CI为0.589~0.771),P均<0.05;hs-cTnT截断值为15.42pg/mL时,灵敏度和特异度分别为86.50%和86.10%。结论 AMI患者hs-cTnT水平明显升高,在鉴别诊断AMI中有较好的诊断效能,值得临床推广。
