摘　　要：目的对比分析急性冠脉综合征(acute coronary syndrome,ACS)与稳定型心绞痛(stable angina,SA)患者冠脉斑块在320排CT心脏血管造影(320-CTA)图像上特征,为临床早期识别ACS提供依据。方法回顾性分析143例冠心病患者数据,其中ACS84例,SA59例,分析冠脉斑块在320CTA图像上表现。结果 ACS患者冠脉混合斑块发生率、受累冠脉节段总数及在冠脉主要分支上的分布、多节段受累患者数、点状钙化斑块的发生率及受累冠脉正性重构发生率方面显著高于SA患者。结论 ACS患者冠脉斑块负荷更大,更多侵犯冠脉三大分支,斑块更多表现为点状钙化,受累冠脉更多发生正性重构。Objective To compare the characteristics of coronary plaques of acute coronary syndrome （ACS） and stable angina （SA） patients by 320-slice CTA. Methods 320-CTA images of 143 patients （ACS 84, SA 59 ） were analyzed and compared by retrospective study. Results The frequency of mixed plaques, the sum and distribution of eroded segments, patients with two or more impaired coronary segments, spotty calcification, positive remodeling were significantly higher in ACS group than in SA. Conclusion Coronary plaque burden is more heavier in ACS patients, with more spotty calcification and positive remodeling.
