摘要(Abstract)：

目的探讨冠状动脉造影对识别急性心肌梗死罪犯斑块病理类型的价值。方法连续入选OCTAMI研究中前223例经光学相干断层成像(OCT)证实罪犯斑块类型的急性ST段抬高型心肌梗死患者的资料,其中斑块破裂130例(斑块破裂组),斑块侵蚀93例(斑块侵蚀组),结合患者临床特征进行比较分析。结果两组患者性别、高血压病、吸烟、高脂血症、陈旧性心肌梗死、缺血性卒中等比较,差异均无统计学意义(均P>0.05)。斑块破裂组患者年龄[(60.16±10.59)岁比(55.19±10.04)岁,P<0.001]、糖尿病比例(33.8%比18.3%,P=0.010)显著高于斑块侵蚀组。冠状动脉造影显示,斑块侵蚀组单支病变明显高于斑块破裂组(57.0%比36.2%,P=0.004),而三支病变(16.1%比31.5%,P=0.004)少于斑块破裂组,分叉病变在两组中差异无统计学意义(31.2%比36.2%,P=0.440)。logistic多因素回归分析显示,冠状动脉造影显示瘤样扩张伴对比剂滞留患者发生斑块破裂的风险是斑块侵蚀组的2.20倍(95%CI 1.25～4.32,P=0.008);糖尿病(OR 1.15,95%CI 1.00～3.86,P=0.031)、病变支数(OR 1.49,95%CI 1.26～3.98,P=0.049)、钙化(OR 1.11,95%CI 1.00～8.76,P=0.050)和术前C反应蛋白水平(OR 1.09,95%CI 1.01～4.90,P=0.043)与斑块破裂的发生独立相关。冠状动脉造影诊断斑块破裂的真阳性率为76.9%,真阴性率为44.1%,与OCT诊断斑块类型的总符合率为63.2%。结论冠状动脉造影有助于判定斑块类型。破裂多见于年龄偏大、合并糖尿病和多支病变患者,瘤样扩张伴对比剂滞留可能是特征性表现,而侵蚀多见于单支病变患者。
