急性心肌梗塞(AMI)大多由于冠状动脉血栓阻塞所致,因此其急性治疗为尽快在梗塞区建立冠脉内血流,并保持完全及持久的通畅以限制心肌坏死,改善预后以及降低死亡率。目前有2种治疗方法,溶栓治疗和经皮冠状动脉腔内成形术(PTCA)。关于溶栓治疗,根据以往报道在发病后60～90min内进行已肯定能消除典型AMI疼痛及全身出冷汗等症状,并能降低抬高的ST段,从而减少住院死亡率3％～4％,再通率为50％～60％,但此疗法主要的问 Acute myocardial infarction (AMI) is mostly due to occlusion of coronary artery thrombosis, so its acute treatment is to establish intracoronary blood flow in the infarct zone as soon as possible while maintaining complete and sustained patency to limit myocardial necrosis, improve prognosis, and reduce mortality. There are currently 2 treatments, thrombolytic therapy and percutaneous transluminal coronary angioplasty (PTCA). About thrombolytic therapy, according to previously reported in the 60 ~ 90min after the onset of the disease has been able to eliminate typical symptoms such as pain and systemic symptoms such as cold sweats, and can reduce the elevated ST segment, thereby reducing hospital mortality 3% to 4% Recanalization rate of 50% to 60%, but the main question of this therapy
