目的 :探讨心肌缺血预适应对急性心肌梗死 (AMI)近期预后的影响。方法 :对 136例 AMI患者的临床资料进行分析 ,按梗死前有无心肌缺血心绞痛史分为 A、B两组进行比较。结果 :A组心肌梗死面积、心肌酶峰值、心律失常、左心衰、休克及病死率明显低于 B组。结论 :表明心肌缺血预适应有保护心肌缩小梗死面积、维护梗死后心脏功能、降低心律失常发生率、减少病死率的作用。
Objective: To investigate the effect of myocardial ischemic preconditioning on the short-term prognosis of acute myocardial infarction (AMI). Methods: The clinical data of 136 patients with AMI were analyzed according to the history of myocardial infarction with or without pre-infarction angina pectoris was divided into A and B groups for comparison. Results: The infarct size, peak myocardial enzymes, arrhythmia, left heart failure, shock and mortality in group A were significantly lower than those in group B. Conclusion: It shows that myocardial ischemic preconditioning can protect myocardial infarction area, maintain cardiac function after infarction, reduce the incidence of arrhythmia and reduce mortality.
