目的分析冠脉造影正常的急性心肌梗死(AMI)的主要危险因素。方法选择冠脉造影正常的AMI患者20例为A组,冠脉造影严重狭窄的AMI患者20例为B组,比较2组患者主要危险因素。结果 A组中患者年龄较年轻、女性患者人数较少(P<0.05),A组中大量吸烟比例明显高于B组(P<0.05),A组中多无高血压、高胆固醇血症及糖尿病病史(P<0.05)。结论冠脉造影正常的AMI多见于年轻男性,吸烟是冠脉造影正常的AMI主要危险因素。
Objective To analyze the main risk factors of acute myocardial infarction (AMI) with normal coronary angiography. Methods 20 AMI patients with normal coronary angiography were selected as group A, 20 AMI patients with severe coronary artery stenosis were selected as group B, and the main risk factors were compared between the two groups. Results The patients in group A were younger and the number of female patients was less (P <0.05). The proportion of smoking in group A was significantly higher than that in group B (P <0.05). There was no hypertension, hypercholesterolemia in group A and Diabetes history (P <0.05). Conclusion AMI with normal coronary angiography is more common in young men. Smoking is the main risk factor of AMI with normal coronary angiography.
