溶栓疗法是近年来治疗急性心肌梗死(AMI)的一大进展。发病后越早应用溶栓药效果越好。通过榕栓使冠脉内血栓溶解,冠脉重新通畅以恢复心肌灌注,从而挽救濒死的心肌。目前对于中老年AMI病人的溶栓治疗多被视为相对禁忌,认为这类病人溶栓治疗病死率高,严重并发症多,利少弊多。本文 Thrombolytic therapy is a major advance in the treatment of acute myocardial infarction (AMI) in recent years. The sooner the onset of the application of thrombolytic drugs the better. Coronary thrombus is dissolved by Fung suppository and the coronary artery is reopened to restore myocardial perfusion, thus saving the dying myocardium. Thrombolytic therapy for AMI in middle-aged and elderly patients is currently considered to be relatively contraindicated, suggesting that such patients have high rates of thrombolysis, high rates of serious complications, and more.
