对47例胸痛伴心电图心肌缺血患者作冠状动脉造影,结果发现30例冠状动脉有狭窄或阻塞,与门诊急诊冠心病诊断的阳性符合率为64%,其中19例心肌梗塞组阳性率89%,17例心绞痛组为76%,而11例可疑心绞痛组仅为9%;31例平板运动试验与冠脉造影阳性符合率为60%.提示临床对胸痛伴心肌缺血者宜作冠状动脉造影以明确诊断,尤其对不典型胸痛和单纯以ST-改变者的冠状动脉造影更重要. 47 cases of chest pain with ECG myocardial ischemia in patients with coronary angiography and found that 30 cases of coronary artery stenosis or obstruction and outpatient emergency diagnosis of coronary heart disease was 64% positive, of which 19 cases of myocardial infarction positive rate of 89% , 17 cases of angina pectoris group was 76%, while 11 cases of suspected angina pectoris group was only 9%; 31 cases of treadmill exercise test and coronary angiography positive coincidence rate of 60% .That clinical chest pain with myocardial ischemia should be made for coronary angiography To confirm the diagnosis, especially for atypical chest pain and simple ST-change coronary angiography is more important.
