本文对１９７例冠状动脉造影（简称ＣＡＧ）进行分析研究，发现９９例冠状动脉病变共累及１６８支血管，以左前降支受累最多，占４２％（７１支）；右冠脉和左旋支受累分别为３０％和２５％（５０支和４２支）；左冠主干病变仅５支。病变以中度、重度狭窄为主，占８３％（１４０支）。文中通过冠心病组和不明原因胸痛组的ＣＡＧ分析对比，认为ＣＡＧ未检出冠脉病变者，也应密切结合临床症状与检查或慎行药物激发试验，以免部分病人发生漏诊。分析结果表明：冠状动脉造影是显示冠脉病变最精确的检查方法；室壁瘤发生的部位与其供血冠脉有直接关系。
In this paper, 197 cases of coronary angiography (referred to as CAG) were analyzed and found 99 cases of coronary artery lesions involving a total of 168 vessels, left anterior descending artery involvement, accounting for 42% (71); right coronary artery and left circumflex artery involvement 30% and 25% (50 and 42); only 5 left main coronary artery lesions. Moderate, severe stenosis, accounting for 83% (140). Through coronary angiography and unexplained chest pain in patients with CAG analysis of comparison, that CAG did not detect coronary lesions, should also be closely combined with clinical symptoms or cautious drug challenge test, so as to avoid missed diagnosis in some patients. The results of the analysis show that coronary angiography is the most accurate method for detecting coronary lesions. The site of aneurysm is directly related to the coronary artery.
