不稳定型心绞痛与急性心肌梗死危险因素及冠状动脉造影病变特点的比较

根据临床和冠状动脉造影结果将122例冠心病患者分为不稳定型心绞痛（UA）组60例和急性心肌梗死（AMI）组62例，对UA与AMI危险因素及病变特点进行比较分析。结果：冠心病的危险因素年龄、高血压、高血脂、糖尿病和吸烟等在UA组及AMI组经统计学处理均无显著性差异（P＞0．05）。冠状动脉造影：单支病变在UA组明显多于AMI组，多支病变在UA组明显少于AMI组，两组间数据经统计学处理均有显著性差异（P＜0．05）；回旋支、右冠状动脉病变在AMI组明显高于UA组，两组间数据经统计学处理有显著性差异（P＜0．05）；完全阻塞和狭窄≥95％在AMI组明显高于UA组，两组间数据经统计学处理有显著性差异（P＜0．001和P＜0．005）。结论：冠心病的危险因素年龄、高血压、高血脂、糖尿病、吸烟及其病程与冠心病的病变程度无相关性；冠状动脉造影显示UA和AMI病变特点有显著性差异。

The comparisons of risk factors and disease characteristics between unstable angina and acute mycocardial infarction

To explore the difference of risk factors,disease characteristics between unstable angina(UA) and acute myocardial infarction(AMI), 60 UA and 62 AMI who were diagnosed clinically and confirmed by coronary angiography were sludied The results showed age, hypertension, hyperlipemia, diabetic mellitus(DM) and smoking were considered risk factors of coronary heart disease(CHD), there was no significant difference between UA group and AMI group (P>0 05) Coronary angiography confirmed there was significant difference on one vessel disease with multi vessel disease between UA group and AMI group (P<0 05), there were significant differences on LCX and RCA between AMI group and UA group (P<0 05) There was significant difference on 100% stricture and above 95% stricture between AMI group and UA group (P<0 001 and P<0 005) This suggested the risk factors as age, hypertension, hyperlipemia, DM and smoking didn't have obvious relativity with the degree of CHD There were significant characteristic differences in coronary angiography between AMI group and UA group
