【摘要】 1例老年男性患者因持续胸闷1 h入院。既往有糖尿病和高血压病史。心电图示Ⅱ、Ⅲ、AVF、V₇～V₉导联ST段抬高0.1～0.2 mV。诊断为急性ST段抬高型心肌梗死，立即进行急诊经皮冠状动脉介入治疗（PCI）,开通梗死相关动脉右冠状动脉左室后支。患者PCI后出现左心衰竭和心源性休克，在主动脉内球囊反搏支持下再次行急诊PCI处理罪犯血管左前降支。经积极治疗后，患者病情好转出院。更多还原

【Abstract】 An elderly male patient was admitted with persistent chest tightness for 1 hour. He had a previous history of diabetes mellitus and hypertension. ECG showed Ⅱ, Ⅲ, AVF, V₇-V₉lead ST segment elevation up to 0.1-0.2 mV. Acute ST segment elevation myocardial infarction was diagnosed, and emergency percutaneous coronary intervention（PCI） was performed immediately, to open the infarction-related artery, posterior left ventricle branch of right coronary artery. After PCI, left ventricular failure and cardiogenic shock were developed. We handled the left anterior descending artery of the culprit vessel in second emergency PCI supported by intra-aortic balloon pump（IABP）. After that, the patient’s condition improved and was discharged from the hospital.更多还原
