目的:探讨肌钙蛋白I(TnI)水平检测对急诊心房颤动患者的临床作用及预测价值。方法:回顾性分析我院662例急诊心房颤动患者的临床资料,依据TnI水平将患者分为A组220例(TnI轻度升高)、B组283例(TnI正常)、C组159例(未检测TnI)。主要终点为1年内全因死亡及急性心肌梗死(AMI)。结果:A组患者复合终点事件、AMI发生率显著高于B组和C组(P<0.01),但3组患者1年内总体病死率比较差异无统计学意义。结论:TnI轻度升高与冠状动脉疾病发生率及AMI发生率增加有关。
Objective: To investigate the clinical effect and predictive value of TnI detection in patients with acute atrial fibrillation. Methods: The clinical data of 662 patients with acute atrial fibrillation in our hospital were retrospectively analyzed. According to the level of TnI, 220 patients were divided into group A (mild increase of TnI), group B (n = 283), group C (n = 159) TnI not detected). The primary endpoint was all-cause death and acute myocardial infarction (AMI) within 1 year. Results: The incidence of AMI in group A was significantly higher than that in group B and group C (P <0.01). However, there was no significant difference in the overall mortality rate among the three groups in one year. Conclusion: The mild increase of TnI is associated with the incidence of coronary artery disease and AMI.
