摘要
本文报道我院1982年～1992年选择性冠状动脉造影600例的X线征象。右、左冠脉优势型及均衡型分别为332例(73.7%)、77例(17%)及44例(9.7%)。冠心病547例冠脉受累共963支,其中LM、LAD、D_1、LCX及RCA分别为50支(5.2%)、369支(38.3%)、80支(8.3%)、210支(21.8%)及254支(26.4%)。冠脉狭窄程度和支数与年龄有密切相关性。左室造影显示的左心射血分数(LVEF)与冠脉狭窄程度及是否合并室壁瘤有明显关系。狭窄严重合并室壁瘤者左室射血分数明显下降,与无室壁瘤相比P<0.01。
600 cases of selective coronary arteriographic signs have been studied since 1982. There are 456 males and 144 females, age ranged 7 to 82 years, the mean age is 52, 2 years. The type of right dominat, left dominat and balanced coronary artery are 332(73.7%), 77(17%), 44(9.7%) respectively. 369 patients suffered from stenotic arteriosclerotic coronary artery disease. The number of involved branches of coronary artery are 50(5.2%) of left main trunk (LM), 369(38%) of left anterio descending(LAD), 80(8.9%) of diagonal branches (D_1), 254(26.4%), 210(21.8%) of right coronary artery(RCA). The degree of coronary stenosis is closely related with age and involved branches of coronary artery, The left ventricular ejection fraction (LVEF) which is showed by left ventriculography is also related with the degree of coronary stenosis and whether to combine with ventricular aneurysm. The LVEF decreased sharply as the patient suffered from severe coronary stenosis and ventricular aneurysm.
