溶栓疗法对降低心肌醒塞(MI)病死率一直是有效的。MI病人接受溶栓者日益增多,但遗留冠状动脉(冠脉)损害和可能再发生缺血。本文探讨溶栓疗法几个方法的进展。立即或延迟作血管成形术; 作过溶栓疗法病人再梗塞的危险性增加。从Schaer等的资料,接受溶栓剂病人早期非致命性的再梗塞发生率是4.5%,对照组为2.1%。再次血管化特别是血管成形术是作为避免这种溶栓后“加倍缺血危险”的一种肯定的方法。有3个试验说明立即作血管成形术在死亡率、输血率方面及须作紧急旁路手术方面较延迟作血管成形术更高。现在认
Thrombolytic therapy has been effective in reducing myocardial infarction (MI) mortality. Increased thrombolysis is accepted in patients with MI but with impaired coronary artery (coronary) and possible re-ischemia. This article explores the progress of several methods of thrombolytic therapy. Immediate or delayed angioplasty; increased risk of reinfarction in patients undergoing thrombolytic therapy. According to Schaer et al, the incidence of early non-fatal reinfarction in patients receiving thrombolytic agents was 4.5% and in controls 2.1%. Vascularization, especially angioplasty, is a sure way of avoiding “doubling the risk of ischemia” after such thrombolysis. Three trials showed that immediate angioplasty was more effective than delaying angioplasty in terms of mortality, blood transfusion rates, and the need for emergency bypass surgery. Now recognize
