目的探讨非典型急性心肌梗死(AMI)的发病机制及临床特点。方法选择26例2014年1月~2016年6月在本院接受治疗的非典型AMI患者作为非典型AMI,选择同期接受诊治的典型AMI患者作为典型AMI组,对比分析2组患者临床特点。结果在心肌梗死部位上,非典型AMI组下壁、前壁心肌梗死发生显著低于典型AMI组(P<0.05);非典型AMI组患者发病至就诊时间显著长于对照组典型AMI组(P<0.05);非典型AMI患者临床症状表现出多样化,且缺乏典型性。结论非典型急性心肌梗死临床特点有多样性,临床诊断过程中须结合相关检查结果及患者临床症状进行综合考虑,进而对患者病情诊断。
Objective To investigate the pathogenesis and clinical features of atypical acute myocardial infarction (AMI). Methods Twenty-six patients with atypical AMI who were treated in our hospital from January 2014 to June 2016 were selected as typical AMI patients for typical AMI. The clinical features of the two groups were compared and analyzed. Results In AMI group, the incidence of inferior wall and anterior myocardial infarction in AMI group was significantly lower than that in typical AMI group (P <0.05). The onset time to arrival time in AMI group was significantly longer than that in AMI group (P < 0.05). The clinical symptoms of patients with atypical AMI showed diversification and lack of typicality. Conclusions The clinical features of atypical acute myocardial infarction are diverse. In the process of clinical diagnosis, they should be combined with the relevant examination results and the clinical symptoms of the patients to consider them comprehensively, and then diagnose the patients’ condition.
