心肌梗塞复发是指新的坏死灶发生于心脏功能和形态学代偿改变之前、第一次梗塞之后。心肌梗塞复发一般是在冠状动脉粥样硬化长期进展的基础上发生,其特征是:心肌各阶段损害、有溶化的坏死灶存在、疤痕形成过程迟缓,病程期长和严重。共观察33例心肌梗塞病人,17例35～59岁病人中有4例复发,16例60～74岁病人中有8例复发,这12例复发者中10例发生在早期,即在第一次梗塞后头三周内发生复发。所有病例在1～3天、7、14、21、30和45天时静脉抽血10毫升作动态检验,进行外周血中性白细胞的碱性磷酸酶、过氧化物酶、
Recurrence of myocardial infarction refers to the occurrence of new necrotic lesions before cardiac function and morphological compensatory change, after the first infarction. Myocardial infarction recurrence generally occurs on the basis of the long-term progression of coronary atherosclerosis, which is characterized by various stages of myocardial damage, the presence of a melted necrotic lesion, a slow scarring process, long and severe duration of disease. A total of 33 patients with myocardial infarction were observed, 4 of 17 patients aged 35- 59 years relapsed, and 8 of 16 patients aged 60-74 years relapsed. Of the 12 patients who relapsed, 10 occurred early, Recurrence occurred within the first three weeks after infarction. All cases in 1 to 3 days, 7,14,21,30 and 45 days venous blood 10 ml for dynamic testing, the peripheral blood neutrophils alkaline phosphatase, peroxidase,
