目的　探讨焦虑、抑郁情绪对AMI临床及心电图的影响。方法　对 12 5例AMI患者分别进行SAS、SDS测定 ,按有无焦虑、抑郁分组 ,对其院内的临床及心电图进行分析。结果　显示 37.6 %、44 .8%的病例分别存在焦虑、抑郁情绪 ,且焦虑、抑郁者VT Vf及 /或SCD、梗死后心绞痛、再梗死的发生率显著高于无焦虑、抑郁情绪者 (P <0 .0 5 )。而AMI发病年龄、性别、梗死部位、血清酶谱及非SCD死亡 ,无显著性差异 (P >0 .0 5 )。结论　AMI病例发生焦虑、抑郁情绪 ,是引发冠脉事件、SCD的主要危险因素 ,严重影响AMI患者的病情演变及生活质量 Objective To investigate the effects of anxiety and depression on the clinical and electrocardiogram (ECG) of AMI. Methods A total of 125 patients with AMI were measured by SAS and SDS, and their clinical and electrocardiogram were analyzed according to the presence or absence of anxiety and depression. The results showed that 37.6%, 44.8% cases were anxiety and depression, and the incidence of VT Vf and / or SCD, angina pectoris and re-infarction in anxiety and depression were significantly higher than those without anxiety and depression <0 .0 5). There was no significant difference in the age, sex, infarction location, serum enzyme and non-SCD of AMI (P> 0.05). Conclusions The occurrence of anxiety and depression in patients with AMI is the main risk factor of coronary events and SCD, which seriously affects the evolution of disease and quality of life in AMI patients
