Abstract

To help guide physicians in their evaluation of patients with acute coronary syndromes, we investigated whether elevated cardiac troponin I in patients presenting with unstable angina predicts ischemia on stress testing. Elevated cardiac troponin I in patients who present with chest pain and normal creatine kinase levels is associated with ischemia on stress testing, as well as with future cardiac events.

摘要

为帮助指导医生评估急性冠脉综合征患者，我们研究了不稳定型心绞痛患者中肌钙蛋白I升高是否预示着负荷试验时存在心肌缺血。胸痛且肌酸激酶水平正常的患者中，肌钙蛋白I升高与负荷试验时的心肌缺血以及未来心脏事件相关。
