摘 要 目的 评估左心辅助装置(LVAD)植入术后患者在基因检测指导下服用华法林抗凝治疗的有效性和安全性,并分析华法
林抗凝效果的影响因素。方法 选择2023年1月至2024年10月在江苏省苏北人民医院心脏大血管中心接受LVAD植入术且需服
用华法林抗凝治疗的患者为研究对象,根据其是否进行CYP2C9和VKORC1基因检测分为基因检测组(n=51)和经验给药组(n=
17)。基因检测组依据基因检测计算出的预测剂量给予华法林,经验给药组由临床医生根据国际标准化比值(INR)经验性地给予
华法林,每天1次。随访观察6个月,比较两组患者华法林治疗的有效性[治疗目标范围内的时间百分比(TTR)、首次达到治疗INR
所需的时间、栓塞事件发生率、INR<1.5事件发生率]和安全性(大、小出血事件和INR>3.5事件发生率)。根据患者TTR是否≥
60%分为TTR≥60%组(n=20)和TTR<60%组(n=48),采用单因素和多因素二元Logistic回归分析法分析患者华法林抗凝效果
的影响因素。结果 基因检测组患者的 TTR 显著高于经验给药组(P<0.05),INR<1.5 事件发生率显著低于经验给药组(P<
0.05);小出血事件发生率和INR>3.5事件发生率均低于经验给药组,但差异均无统计学意义(P>0.05)。多因素二元Logistic回
归分析结果显示,进行基因检测为华法林抗凝治疗的独立保护因素[比值比(OR)=10.842,95%置信区间(CI):1.211~27.037,P=
0.033],联用他汀类药物为华法林抗凝治疗的独立危险因素[OR=0.196,95%CI:0.045~0.861,P=0.031]。结论 对于LVAD植入
术后患者,基因检测指导下采用华法林抗凝治疗可提高TTR,缩短抗凝达标时间,且安全性良好;但需注意,他汀类药物联用可能
增强华法林的抗凝效果,从而增加患者出血风险。

ABSTRACT OBJECTIVE To evaluate the effectiveness and safety of warfarin anticoagulation therapy guided by gene test in
patients undergoing left ventricular assist device (LVAD) implantation, and to analyze the influencing factors of warfarin
anticoagulation efficacy. METHODS Patients who underwent LVAD implantation at the Heart and Vascular Center of Northern
Jiangsu People’s Hospital from January 2023 to October 2024 and required warfarin anticoagulant therapy were selected as the
study subjects. They were divided into genetic testing group (n=51) and empirical treatment group (n=17) based on whether they
underwent CYP2C9 and VKORC1 gene test. The gene test group was given warfarin based on the predicted dose calculated by gene
test, while the empirical treatment group was given warfarin by clinical doctors based on international normalized ratio (INR)
experience, all patients were given warfarin once a day. Follow-up observation was conducted for 6 months to compare the
effectiveness [time in therapeutic range(TTR), the time required to reach INR for the first time, the incidence of embolic events,
the incidence of INR<1.5 events] and safety (the incidence of major and minor bleeding events,the incidence of INR>3.5 events)
of warfarin treatment between two groups of patients.
