目的 :探讨再发急性心肌梗死 (AMI)患者的临床特征。方法 :将再发 AMI患者 36例与同期患有AMI,出院后无再梗死的 6 9例患者对比 ,分析其临床特征。结果 :与 AMI者比较 ,发生再梗死时 ,症状多不典型(2 7.8% ,6 9.4% ,P <0 .0 1) ;多支病变者显著高于无再梗死者 (72 .2 % ,47.8% ,P <0 .0 1) ;冠状动脉病变积分亦显著高于无再梗死者 (12 .75± 5 .6 1,8.96± 3.48,P <0 .0 1) ;再梗死者的血总胆固醇水平显著高于无再梗死者(5 .6 9± 1.34 ,3.95± 1.73,P <0 .0 5 ) ;血糖水平亦高于后者 (9.2 1± 1.39,7.0 3± 1.97,P <0 .0 5 )。结论 :再梗死患者多具有严重的冠状动脉多支病变 ,再梗死时临床症状多不典型 ,其血总胆固醇和血糖水平增高为主要的危险因素
Objective: To investigate the clinical features of patients with recurrent acute myocardial infarction (AMI). Methods: The clinical features of 36 patients with recurrent AMI were compared with 69 AMI patients with AMI in the same period and no further infarction after discharge. Results: Compared with those with AMI, the symptoms were more atypical than those with AMI (2 7.8%, 6 9.4%, P <0.01); those with multi-vessel disease were significantly higher than those without AMI (72.2% 47.8%, P <0.01). The score of coronary artery disease was also significantly higher than that of patients without re-infarction (12 .75 ± 5 .6, 1,8.96 ± 3.48, P <0.01) The total cholesterol level was significantly higher than that of the patients without any further infarction (5.96 ± 1.34, 3.95 ± 1.73, P <0.05), and the blood glucose level was also higher than the latter (9.2 ± 1.39, 7.03 ± 1.97, P < 0 .0 5). Conclusion: Most patients with recurrent infarction have severe multi-vessel disease of coronary artery. The clinical symptoms of atherosclerotic infarction are often atypical. The increase of blood total cholesterol and blood glucose are the main risk factors
