摘  要:目的探讨围手术期D-二聚体和组织因子(TF)-1208 D/I基因多态性对非体外循环冠状动脉旁路移植术(OPCABG)患者远期预后的影响。方法回顾性分析2015年5月至2016年5月天津医科大学总医院收治的首次行OPCABG患者的病例资料,记录患者的一般资料、手术时间、搭桥支数、左室射血分数(LVEF)、24 h胸腔积液引流量、术中肝素用量、联合抗凝和抗血小板时间、术后呼吸机使用时间等指标,术前及术后1、4、7、14 d和1、2、3个月的血生化指标,围手术期并发症,以及不同TF-1208 D/I基因多态性患者D-二聚体水平等,随访1年的预后。采用Logistic回归分析术后1年再发心绞痛的危险因素。结果OPCABG术后患者血浆D-二聚体水平持续升高,术后1个月达到高峰〔1.94(1.07,2.70)mg/L〕,随后下降,3个月时已降至术前水平〔0.20(0.10,0.45)mg/L〕。TF-1208 I I基因型患者术后14 d和1个月的D-二聚体水平(mg/L)显著高于DD基因型和D/I基因型患者〔14 d:4.17(1.54,5.09)比1.91(1.07,2.26)、1.02(0.91,1.88),1个月:5.12(2.41,6.32)比1.94(1.18,2.70)、1.62(0.22,1.88),均P〈0.05〕。1年随访结果显示,25例患者再发心绞痛,无心肌梗死发生。TF-1208 I I基因型患者发生心绞痛的比例显著高于其他基因型患者(χ2=0.197,P=0.004)。Logistic回归分析显示,术前LVEF〈0.50〔优势比(OR)=6.482,95%可信区间(95%CI)=1.365-18.763,P=0.015〕和TF-1208 I I基因型(OR=8.864,95%CI=1.613-46.743,P=0.012)是OPCABG患者术后1年再发心绞痛的独立危险因素。结论OPCABG术后机体处于相对高凝状态并持续较长时间,术后3个月基本恢复;术前心功能差和TF-1208 I I基因型是术后再发心绞痛的独立危险因素。ObjectiveTo investigate the effect of perioperative period D-dimer and tissue factor (TF)-1208 D/I gene polymorphism on the long-term prognosis of patients with off-pump coronary artery bypass grafting (OPCABG).MethodsRetrospective analysis of the case data of the first OPCABG patients admitted to Tianjin Medical University General Hospital from May 2015 to May 2016 were enrolled. The general data, operation time, bypass number, left ventricular ejection fraction (LVEF), flow rate of 24-hour pleural effusion, intraoperative heparin dosage, combined anticoagulant and antiplatelet time, and the time of postoperative ventilator were measured. The blood biochemical indexes of 1, 4, 7, 14 days and 1, 2, 3 months after operation, perioperative complications, the level of D-dimer in the patients with different TF-1208 D/I gene polymorphism, and prognosis of 1-year follow-up were recorded. The risk factors of recurrent angina 1 year after operation was analyzed by Logistic regression analysis.ResultsThe level of plasma D-dimer was increased continuously after OPCABG, and reached a peak at 1 month after operation [1.94 (1.07, 2.70) mg/L], then decreased, and decreased to preoperative level 3 months after operation [0.20 (0.10, 0.45) mg/L]. The level of D-dimer in TF-1208 I I genotype was significantly higher than that in TF-1208 DD genotype and TF-1208 D/I genotype group at 14 days and 1 month after operation [mg/L: 4.17 (1.54, 5.09) vs. 1.91 (1.07, 2.26), 1.02 (0.91, 1.88) at 14 days; 5.12 (2.41, 6.32) vs. 1.94 (1.18, 2.70), 1.62 (0.22,1.88) at 1 month, all P 〈 0.05]. The results of 1-year follow-up showed that 25 patients with recurrent angina pectoris without the occurrence of myocardial infarction. The proportion of recurrent angina pectoris in TF-1208 I I genotype was significantly higher than that in TF-1208 DD genotype and TF-1208 D/I genotype group (χ2 = 0.197, P = 0.004). Logistic regression analysis showed that LVEF 〈 0.50 [odds ratio (OR) = 6.482, 95% c
