ACC/AHA guidelines assign a class I indication for use of myocardial perfusion imaging (MPI) for the evaluation of chest pain in patients with acute coronary syndromes and a nondiagnostic ECG. However, MPI is not a widely used modality for the evaluation of patients who present to the ER with chest pain and an intermediate pretest probability for coronary artery disease.We report a case in which resting MPI was pivotal in diagnosing acute myocardial infarction and expedited the appropriate reperfusion strategy.
ACC/AHA 指南将心肌灌注成像(MPI)用于评估急性冠状动脉综合征和心电图无诊断性的胸痛患者列为 I 类适应证。然而,MPI 并不是评估因胸痛和中等程度的冠心病前期概率而就诊于急诊室的患者的常用方法。我们报告了一个病例,其中静息 MPI 对诊断急性心肌梗死起关键作用,并加速了适当的再灌注策略。
