摘要
目的探讨血清心肌钙蛋白Ⅰ(cTnⅠ)水平对不稳定型心绞痛(UA)患者近期预后的评估作用。方法采用化学发光法测定62例UA患者入院时血清cTnⅠ含量,以cTnⅠ>0·4μg/L为界值,将患者分为cTnⅠ增高组和正常组,追踪1个月,比较两组心脏事件发生率。结果在62例UA患者中,cTnⅠ增高组24例出现心脏事件8例,正常组38例出现2例,两组间心脏事件发生率差异有统计学意义(P<0·05);cTnⅠ增高对心脏事件的阳性预测值和阴性预测值分别为33·3%和94·7%。结论血清心肌钙蛋白Ⅰ水平对UA患者的近期预后有预测作用。
Objective To study the predictive value of the level of serum cardiac troponin Ⅰ （cTn Ⅰ ） for the short-term risk in patients with unstable angina（UA）. Methods Serum levels of cTn Ⅰ of 62 patients with UA were measured with automated chemiluminescence assay on admission, cTn Ⅰ 〉 0.4μg was defined as the cutoff, then these patients were divided into two groups, the elevated group and the normal group, and were followed up for a month to compared with the rate of cardiac events. Results Among the 62 cases, there were 8 cardiac events in the evelated group of 24 patients. 2 cardiac events in the normal group of 38 patients. There was a significant difference between the two groups（P〈0.05） .The postive predictive value of elevated cTn Ⅰ for this risk was 33.3%, the negative predictive value was 94.7 %. Conclusion The serum level of cTn Ⅰ is related to the short-term risk in patients with UA.
