目的：分析冠心病的冠状动脉造影表现。材料与方法3对50例临床疑诊冠心病患者进行选择性冠状动脉和左室造影。结果：（1）右冠优势型42例（84．0％），左冠优势型3例（10.0％）．均衡型5例（10．0％）。（2）冠状动脉单支病变10例，双支病变8例，3支病变3例，共累及37支血管，分别为前降支16支（43．2％），右冠状动脉11支（29．7％），左回旋支8支（21．6％）及左冠主干2支（5．4％）．冠状动脉狭窄以中一重度多见，占26支（70．3％）。（3）10例见侧支循环。（4）发现室壁瘤5例。结论：（1）选择性冠状动脉造影是确诊冠心病的手段，可为临床治疗提供依据。（2）室壁瘤的形成与冠状动脉分布范围及狭窄程度密切相关。（3）侧支循环能防止心肌梗塞范围扩大和室壁瘤形成。
Objective: To analyze coronary angiography of coronary heart disease. Materials and Methods3 Fifty patients with clinically suspected coronary heart disease underwent selective coronary and left ventricular angiography. Results: (1) There were 42 cases (84.0%) with dominant right coronary artery and 3 cases (10.0%) with dominant left coronary artery. Five cases were balanced (10.0%). (2) There were 10 cases of single coronary artery disease, 8 cases of double-vessel disease and 3 cases of 3 lesions, involving 37 vessels, including 16 anterior descending branches (43.2%), 11 right coronary vessels .7%), the left circumflex branch in 8 (21.6%) and the left main trunk in 2 (5.4%). Severe coronary stenosis in the more common, accounting for 26 (70.3%). (3) 10 cases see collateral circulation. (4) 5 cases of aneurysm were found. Conclusion: (1) Selective coronary angiography is a means of diagnosing coronary heart disease, which can provide the basis for clinical treatment. (2) The formation of aneurysm is closely related to the extent of coronary artery distribution and the degree of stenosis. (3) collateral circulation to prevent the expansion of myocardial infarction and the formation of aneurysm.
