目的:回顾性分析心肌标志物肌钙蛋白I(Troponin I,TnI)在急诊科心房颤动和心房扑动(房颤/房扑)患者的检测情况。方法:收集2010年6月至2011年6月,就诊于北京安贞医院急诊科2 190例房颤/房扑患者病例,随机抽取了500例患者的资料进行回顾性分析,分析内容包括肌钙蛋白I检测次数,TnI阳性率和确诊为急性冠状动脉综合征(ACS)的概率。结果:患者至少有1次TnI检测的为86.8%(434/500),其中TnI阳性率为15.7%,诊断为ACS者的概率为5.1%。至少2次检测的患者为41.8%(209/500),其中TnI阳性率为26.8%(56/209),诊断为ACS的占9.6%。结论:在急诊科,房颤/房扑患者有很高的TnI检测率,而急诊患者确诊为ACS仅约5%,提示急诊内科医师需综合评估房颤/房扑患者临床状况后再进行TnI检测,避免临床资源不必要的浪费。
Objective: To retrospectively analyze the detection of myocardial marker Troponin I (TnI) in emergency department of atrial fibrillation and atrial flutter (atrial fibrillation / atrial flutter). Methods: A total of 2 190 cases of atrial fibrillation / atrial flutter from Emergency Department of Beijing Anzhen Hospital were collected from June 2010 to June 2011. The data of 500 patients were randomly selected and analyzed retrospectively. The number of protein I tests, the positive rate of TnI, and the probability of diagnosis of acute coronary syndrome (ACS). Results: The TnI test was performed in 86.8% (434/500) of patients with at least one TnI test. Among them, the positive rate of TnI was 15.7% and the probability of diagnosing ACS was 5.1%. The number of patients with at least 2 tests was 41.8% (209/500), of which TnI positive rate was 26.8% (56/209) and ACS was 9.6%. CONCLUSIONS: In the emergency department, patients with atrial fibrillation / atrial flutter have a high detection rate of TnI, whereas emergency patients are diagnosed with only about 5% of ACS, suggesting that emergency physicians need a comprehensive assessment of the clinical status of patients with atrial fibrillation / atrial flutter before TnI Detection, to avoid unnecessary waste of clinical resources.
