目的:探讨肌钙蛋白Ⅰ(CTnI)定量检测在急性冠脉综合征(ACS)中的临床应用价值。方法:对139例急性冠脉综合征(ACS)及107例正常对照组进行CTnI定量检测,根据检测结果发现高危患者,观察UA患者CTnI阳性组和CTnI阴性组住院期间心性事件的发生情况,以及CTnI在ACS中的诊断价值。结果:心性事件发生率在UA中CTnI阳性组55.6%(5/9),明显高于CTnI阴性组2.6%(2/77),CTnI定量检测在AMI患者10～24小时阳性率均100%。结论:CTnI定量检测对UA预后判断以及与AMI诊断方面有较好的应用价值。
Objective: To investigate the clinical value of quantitative detection of troponin Ⅰ (CTnI) in acute coronary syndrome (ACS). Methods: 139 patients with acute coronary syndrome (ACS) and 107 normal control group were detected by CTnI. According to the results of the test, high-risk patients were observed in patients with UA CTnI-positive group and CTnI-negative group of hospitalized during the occurrence of cardiac events, and Diagnostic value of CTnI in ACS. Results: The incidence of cardiac events in UA was 55.6% (5/9) in CTnI positive group, which was significantly higher than 2.6% (2/77) in CTnI negative group. The positive rate of CTnI in 10 ~ 24 hours in AMI patients was 100%. Conclusion: CTnI quantitative detection of UA prognosis and AMI diagnosis has good value.
