目的探讨肌钙蛋白T(TnT)与急性冠状动脉综合征(ACS)患者到急诊室72h内发生严重心脏事件的相关性。方法连续观察到急诊室就诊并在24h内进行了TnT检测的ACS患者。对入选患者随访72h,计算发生严重心脏事件的可能性比率。结果352例患者中20例在到达急诊室72h内出现严重心血管事件。可能性比率(和95%置信区间[CI])分别为:TnT<0.5μg/L为0.5(0.3~0.9),0.5μg/L≤TnT≤2.0μg/L为1.6(0.4~6.5),TnT>2.0μg/L为12.5(3.0~51.9)。结论TnT>2.0μg/L与ACS患者72h内发生严重心血管事件的可能性增加相关。
Objective To investigate the correlation between TnT and acute coronary syndrome (ACS) in patients with severe cardiac events within 72 hours from emergency department. Methods ACS patients with emergency room visits and TnT testing within 24 hours were consecutively observed. The selected patients were followed up 72h, calculated the probability of serious heart events ratio. Results Of the 352 patients, 20 had severe cardiovascular events within 72 hours of reaching the emergency room. The odds ratios (and 95% CIs) were: TnT <0.5μg / L 0.5 (0.3-0.9), 0.5μg / L ≦ TNT ≦ 2.0μg / L 1.6 > 2.0 μg / L was 12.5 (3.0 ~ 51.9). Conclusions TnT> 2.0 μg / L is associated with an increased likelihood of a serious cardiovascular event within 72 h of ACS.
