心脏急症处理中有三个主要问题值得讨论:(1)是否应常规使用能“减少梗塞面积”的药物?(2)预防性使用利多卡因是否仍然合适?(3)所有急性心肌梗塞患者是否都应给硝酸甘油? 限制心肌梗塞范围: 心肌梗塞是一个动态过程并可因人们干预而发生变化的概念是在六十年代末和七十年代初建立起来的。自此,人们进行了大量的临床和实验研究,但听得结果不一。造成这种情况的部份原因是缺乏适当的终点指标来评价干预过程和在选择适当干预时间上的 There are three main issues in the management of cardiac emergencies worth discussing: (1) Should conventional use of drugs that “reduce the infarct size” be used? (2) Is prophylaxis with lidocaine still appropriate? (3) Are all patients with acute MI? Limiting myocardial infarct size to nitroglycerin: The notion that myocardial infarction is a dynamic process that changes with human intervention was established in the late 1960s and early 1970s. Since then, a large number of clinical and experimental studies have been conducted, but different results have been heard. Part of the reason for this is the lack of an appropriate end point to evaluate the intervention process and the time it takes to select the appropriate intervention
