摘　　要：目的　探讨梗死相关动脉 (IRA)的血栓阻塞程度与非Q波急性心肌梗死 (AMI)的关系。方法　对 10 4例非Q波AMI患者的冠状动脉造影资料进行分析。结果　研究显示 :非Q波AMI患者IRA完全闭塞发生率为 2 3 1% ,IRA狭窄≥ 95 % ,≥ 90 %和 <90 %分别占 37 5 % ,18 3%和 2 1 1% ,TIMI血流 0 -II级占 6 2 5 %。在“罪犯”血管中有斑块破裂征象者占 71%。在完全闭塞病变的患者中 ,75 %闭塞血管的远端有侧支循环。结论　结果提示 ,非Q波AMI患者较不稳定性心绞痛患者有更为严重的血栓阻塞性病变 。Objective To approach the character of culprit lesions in patients with non-Q-wave acute myocardial infarction (NQWMI). Methods The data of 104 patients with NQWMI who underwent coronary angiography from Jan. 1996 to Dec. 2000 were analyzed. Results The total occlusion of infarct-related artery (IRA)was found in 24 patients with NQWMI constituted 23.1% of all these patients. The percentages for stenoses ≥95%, ≥90% and <90% of IRA were 37.5%, 18.3% and 21.1% respectively in all the patients. The patients with TIMI perfusion grades 0-11 constituted 62.5%. The plaque rupture was found in 71% of patients with non-total occlusion of IRA. There was collateral circulation in 75% of the patients with total occlusion of IRA. Conclusion Our study suggests that the patients with NQWMI have more severe thrombotic obstruction lesions of IRA than those with unstable angina. Reperfusion treatment would be needed in the majority of patients with NQWMI.
