摘要
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。
Purpose: A study of the angiographic findings in coronary heart disease. MateriaIs and Methods: Both coronary ar-teriography and left ventricular cardiography in 50 cases suspected coronary heart disease were performed. Results: (1) The type ofright dominate, left dominate and balanced coronary artery were 42 (84. 0 % ), 3 (6. 'O % ), 5 (10.0% ) respectively. (2) coro-nary atherosclerotic lesion involved single vessel in 10, double vessel in 8 and triple vessel in 3. The incidence of stenosis: left anteriordescending, right coronary, left circumflex and left main trunk were 16 (43. 2% ), 11 (29. 70% ), 8 (21. 6% ), 2 (5. 4% )respectivly. (3) 1O cases of collatera1 circulation and 5 cases of ventricular aneurysm were found. conclusion (1 ) selective coronary arte-riography was the only method for definitive diagnosis of coronary heart disease. It will be useful for clinical treatment. (2) There wasa close relationship between the ventricular aneurysm and locatoins and degree of the coronary artery stenosis. (3) The presence of collat-eral circulation may prevent the en1argement of the infarctive area and the formation of the aneurysm.
