摘 要:目的探讨光学相干断层成像(OCT)检测的冠状动脉支架内异质性新生内膜的影响因素。方法回顾性分析2009年9月至2012年4月在阜外医院进行冠状动脉支架OCT复查的143例冠心病患者的临床资料。根据OCT图像中支架内新生内膜的背散射形态,将患者分为异质性内膜组(26例)和同质性内膜组(117例)。比较两组患者的临床特征及OCT图像特征,并采用二元logistic回归分析支架内异质性新生内膜的相关因素。结果异质性内膜组患者总胆固醇[(5.31±1.11)mmol/L比(4.70±0.94)mmol/L,P=0.005]、低密度脂蛋白胆固醇[(2.57±0.87)mmol/L比(2.29±0.46)mmol/L,P=0.021]、甘油三酯[2.12(1.82~2.87)mmol/L比1.90(1.73-2.11)mmol/L,P=0.015]水平均高于同质性内膜组,因急性冠状动脉综合征接受经皮冠状动脉介入治疗(PCI)的患者比例多于同质性内膜组[23.1%(6/26)比6.8%(8/117),P=0.022]。异质性内膜组患者OCT图像中新生薄壁纤维帽斑块的比例高于同质性内膜组[5.8%(28/481)比3.9%(89/2276),P=0.043]。多因素二元logistic回归分析显示,低密度脂蛋白胆固醇(OR=2.74,95%CI1.04—7.24,P=0.042)、甘油三酯(OR=2.88,95%CI1.05—7.89,P=0.040)、因急性冠状动脉综合征行PCI(OR=12.74,95%CI2.69-60.49,P=0.001)和脑血管疾病(OR=13.09,95%CI2.16~79.53,P=0.005)与支架内异质性新生内膜呈正相关,而支架置入时间(OR=0.63,95%CI0.42—0.96,P=0.033)与支架内异质性新生内膜呈负相关。结论冠状动脉支架内异质性新生内膜与血脂水平、因急性冠状动脉综合征接受PCI和脑血管疾病史相关,可能会影响支架内膜的稳定性。Objective To explore the related factors of optical coherence tomography (OCT) detected in-stent heterogeneous neointimal in coronary stents. Methods A total of 143 cases of coronary heart disease patients with OCT detected in-stent neointimal hyperplasia in Fuwai hospital from September 2009 to April 2012 were included in this study and patients data were retrospectively analyzed. Patients were divided into heterogeneous intima group(26 cases) and homogeneous intima group (117 cases)according to neointimal characteristics. Clinical features and OCT characteristics of the 2 groups were compared and binary logistic regression analysis was performed to analyze the risk factors of in-stent heterogonous neointimal hyperplasia. Results Compared to homogeneous intima group, patients in heterogeneous intima group had significantly higher cholesterol level ( (5.31 ± 1.11 ) mmol/L vs. (4. 70 ± 0. 94) mmol/L, P = 0. 005 ), low-density lipoprotein cholesterol level ( ( 2. 57 ± 0. 87 ) mmol/L vs. ( 2. 29 ± 0. 46 ) mmol/L, P = 0. 021 ) and triglyceride level (2. 12 ( 1.82- 2. 87 ) mmol/L vs. 1.90 ( 1.73 - 2. 11 ) mmol/L, P = 0. 015 ). Moreover, the percent of percutaneous coronary intervention (PCI) because of acute coronary syndrome (23. 1% (6/26) vs. 6. 8% (8/117), P = 0. 022) and the thin cap neoatheroma (5.8% (28/481) vs. 3.9% (89/2 276), P = 0.043) were also significantly higher in heterogeneous intima group than in homogeneous intima group. Binary logistic regression analysis showed that low-density lipoprotein cholesterol (OR = 2. 74, 95% CI 1.04 - 7.24, P = 0. 042), triglyceride (OR = 2. 88, 95% CI 1.05 - 7. 89, P = 0. 040), PCI for acute coronary syndrome ( OR = 12. 74, 95% CI 2. 69 - 60. 49, P = 0. 001 ), and cerebrovascular disease ( OR = 13.09, 95% CI 2. 16 - 79. 53, P = 0. 005 ) were risk factors for in-stent heterogenous intima. Time post stent implantation was protective factor for in-stent heterogenous intima ( OR
