随着冠心病发病率和急性心肌梗塞存活率的增加,再发性心肌梗塞亦逐渐增加。再发心肌梗塞心肌损伤面积大,预后差。预防再梗塞的发生对病死率的降低有重要意义。一、再梗塞的定义一般来讲,在有明确心肌梗塞后出现心电图及酶学的改变,符合心肌梗塞的诊断标准即为再梗塞,但目前临床上还没有严格的标准来区分梗塞面积的扩展与再梗塞,严格的来讲梗塞面积的扩展属于早期再梗塞。从病理上区分,梗塞面积扩展是原梗
With the increasing incidence of coronary heart disease and acute myocardial infarction, recurrent myocardial infarction also gradually increased. Recurrent myocardial infarction myocardial injury area, poor prognosis. Preventing the occurrence of re-infarction on mortality reduction is important. First, the definition of re-infarction In general, there is a clear myocardial infarction electrocardiogram and enzymatic changes in line with the diagnostic criteria for myocardial infarction is re-infarction, but at present there is no strict standard to distinguish the expansion of infarct size And re-infarction, strictly speaking, the expansion of infarct size is early re-infarction. From the pathological distinction, infarction area expansion is the original stem
