Rapid restoration of patency of the infarct-related artery is the key to preserving myocardium and improving survival. This understanding has led to the application of genetic engineering to develop new plasminogen activators with specific clinical features. These novel activators may provide faster and more complete reperfusion in a greater number of patients, and do so with less risk of bleeding and intracranial hemorrhage. This article reviews the pharmacologic profiles and clinical performance of several novel plasminogen activators engineered from the human tissue plasminogen activator molecule or developed from animal and bacterial proteins.
迅速恢复梗死相关动脉的通畅是保护心肌和提高生存率的关键。基于这一认识,基因工程已被应用于开发具有特定临床特征的新型纤溶酶原激活剂。这些新型激活剂可能会使更多患者获得更快、更完全的再灌注,且出血和颅内出血风险更低。本文综述了几种由人组织纤溶酶原激活剂分子改造而来或基于动物及细菌蛋白研发的新型纤溶酶原激活剂的药理学特性和临床表现。
