放射性核素心肌灌注显像在急性冠状动脉综合征中的临床应用

Applications of radionuclide myocardial perfusion imaging in acute coronary syndrome

近年来，急性冠状动脉综合征（ACS）在临床上越来越受到重视。应用放射性核素心肌灌注显像（MPI）可以对常规方法不能明确诊断的急性胸痛患者排除或确诊ACS作出迅速、准确判断，其诊断的灵敏度和阴性预测值均很高。MPI还有助于评价心肌缺血和梗死灶的范围和程度，对ACS患者进行危险分层，为ACS的预后判断和疗效评估提供重要信息。

In recent years, acute coronary syndrome（ACS） has been getting more and more attentions. Radionuclide myocardial perfusion imaging （MPI） can make a quick accurate diagnosis for patients with acute chest pain who cann＇ t be diagnosed by conventional methods. The sensitivity and negative predictive value of MPI are relatively high. Besides, MPI can be applicated in the detection of ischemic and infarct size and degree, the risk stratification and the assessment of prognosis of the patients with ACS, and the appraisal of the effect of strategies.
