高敏肌钙蛋白T在急性非ST抬高型心肌梗死早期诊断中的价值

Value of hs - troponin T （ hs - cTnT） in differential diagnosis of patients with acute non -ST elevation myocardial infarction

目的：探讨高敏肌钙蛋白T（ hs－cTnT）在急性非ST抬高心肌梗死超早期（＜6h）的应用价值。方法：选取2009年8月～2013年3月我院就诊的212名NSTEMI患者，以冠状动脉造影结果、冠状动脉CTA结果作为最终诊断，入院即刻定量测定hs －cTnT和cTnI。结果：在本研究入组的患者中hs－cTnT、cTnI相比具有较好的敏感性和特异性；同时检测hs－cTnT与cTnI2项诊断NSTEMI，均有较高敏感性、特异性、阳性预测值、阴性预测值。结论：高敏肌钙蛋白T（ hs－cTnT）可作为急性心肌损伤检测的一项快速、准确、敏感、特异的指标。

Objective：To explore the application value of hs-troponin T（ hs-cTnT） in NSTEMI early diagnosis.Methods：212 NSTEMI patients in our hospital from 2009.6 to 2012.3 were selected with PCI, CTA results as the diagnostic criteria.Then hs-cTnT and cTnI were collected in early period of NSTEMI.Results：Compared with cTnI, hs-cTnT showed higher sensitivity and specificity,and combining hs-cTnT with cTnI, the sensitivity, specificity, positive and negtive predictive values indicated the combination had the high-est value in diagnosis of NSTEMI.Conclusion：hs-cTnT might be one of the most useful methods in the early diagnosis of NSTEMI.
