摘要
目的探讨消化道大出血合并急性心肌梗死的机制和临床特点。方法 2003年11月—2009年11月分析利辛县人民医院收治消化道大出血并急性心肌梗死20例患者的临床特点、心电图改变、血清心肌酶学测定结果。结果消化道大出血并急性心肌梗死时心电图可示心肌梗死发生的部位及性质,心肌酶谱均升高,病死率高达30%。结论消化道大出血并急性心肌梗死其发病机制与冠状动脉灌流量减少、血管平滑肌收缩、冠状动脉痉挛、狭窄有关。并容易认为由消化系统原发病所致,从而被忽视。为此应注意动态观察其心电图、血清心肌酶学等的变化。
[Objective]To explore mechanism and clinical characteristics of gastrointestinal hemorrhage complicated with acute myocardial infarction.[Methods]The clinical characteristics,electrocardiogram changes and determination results of serum myocardial enzyme of 20 patients with gastrointestinal hemorrhage complicated with acute myocardial infarction who were received by the People＇s Hospitalof Lixin County from November 2003 to November 2009 were analyzed.[Results]When gastrointestinal hemorrhage complicated with acute myocardial infarction happened,electrocardiogram could show the position and character of myocardial infarction,myocardial enzymes all increased,and the mortality reached 30%.[Conclusion]The pathogenesis of gastrointestinal hemorrhage complicated with acute myocardial infarction is related to decrease of coronary artery perfusion flow,shrinkage of vascular smooth muscle,spasm and stenosis of coronary artery.And it used to be neglected because of the misunderstanding that it was caused by the primary disease of digestive system.So the changes of electrocardiogram and serum myocardial enzyme should be observed closely.
