摘要
1 Introduction Effective and timely reperfusion of infarcted coronary artery is crucial to the treatment of patients with ST-segment elevation myocardial infarction(STEMI).[1,2]Current guidelines highly recommend that the door-to-balloon(D2B)time,as a quality metric of primary percutaneous coronary intervention(PCI)in patients with STEMI,should be≤90 min and preferably less than 60 min.[3,4]However,significant variations from guidelines exist in the real world practices at hospitals.
