摘要:

目的 研究闽北地区冠心病(CHD)患者CYP2C19基因的多态性分布特点,并评价依据基因型指导经皮冠状动脉介入术(PCI)后不同抗血小板(PLT)药物治疗的临床预后,为患者PCI术后个体化抗PLT聚集治疗策略提供理论依据。方法 选择临床诊断为CHD、行冠状动脉造影明确CHD、行PCI的并同意配合跟踪随访的患者520例。行CYP2C19基因型检测,所有患者按病变情况需置入药物洗脱支架(DES),且术后根据基因型结合患者冠状动脉病变情况分为快代谢型、中间代谢型和慢代谢型3个组,对各组基因型的分布进行比较,并于术后1、6和12个月随访、记录3个组间主要不良心血管事件(MACE)发生情况。结果 CYP2C19基因多态性的分布特点:CYP2C19纯合子快代谢型224例,占43.07%;中间代谢型227例,占43.65%,其中以681号碱基功能位点突变为主,为186例,占82%;慢代谢型69例,占13.26%。3个组间1年随访MACE的发生率差异无统计学意义(P>0.05)。结论 闽北地区CHD患者CYP2C19等位基因功能缺失(LOF)明显升高。通过基因型检测结果选择不同抗PLT聚集药物或调整抗PLT聚集药物剂量能够有效减少中间代谢型及慢代谢型MACE的发生率,改善CHD患者的长期预后。

Abstract:

Objective To study the distribution characteristic of CYP2C19 gene polymorphism in coronary heart disease (CHD)patients in northern Fujian,to evaluate the clinical prognosis of different anti-platelet (PLT) drug therapies after percutaneous coronary intervention(PCI),and to provide a reference for anti-PLT aggregation treatment. Methods A total of 520 patients diagnosed as CHD by coronary angiography undergoing PCI were enrolled and followed up. CYP2C19 genotype was determined. All patients should be in drug-eluting stents(DES). According to genotypes combined with coronary artery disease severity,the patients were classified into 3 groups(fast,intermediate and slow metabolic types). The distribution of genotypes was assessed. After PCI for 1,6 and 12 months,the occurrence of major adverse cardiovascular events (MACE) was recorded. Results There were 224 (43.07%) cases of CYP2C19 homozygous fast metabolic type. There were 227 (43.65%) cases of intermediate metabolic type,including 186 (82%) cases of 681 base function locus mutation. There were 69 (13.26%) cases of slow metabolic type. After 1-year follow-up,there was no statistical significance for MACE occurrence among the 3 groups (P>0.05). Conclusions CYP2C19 loss-of-function (LOF) increases in patients with CHD in northern Fujian. Through genotype determination,selecting different anti-PLT aggregation drugs or adjusting anti-PLT aggregation drug doses,the occurrence of MACE can decrease,which can improve long-term prognosis in CHD patients.
