摘要
目的:探讨β2肾上腺素能受体(ADRB2)Gln27Glu基因多态性对经皮冠状动脉介入术(PCI)后β受体阻滞剂临床疗效的影响。方法:收集广东省人民医院PCI术后接受β受体阻滞剂治疗的冠心病患者384例,采用TaqMan基因分型技术检测ADRB2 Gln27Glu基因型,分析Gln27Glu基因多态性对主要不良心脏事件(MACE)的影响。结果:基因型分布频率符合Hardy-Weinberg平衡(P>0.05),各基因型患者间的一般临床特征没有显著差异(P>0.05);各基因型患者使用β受体阻滞剂种类的构成无显著差异(2=9.196,P>0.05);Cox单因素分析显示,左主干病变、糖尿病和高血压是发生MACE的相关因素,相对危险度分别为2.661(95%CI:1.122~6.307)、2.431(95%CI:1.127~5.242)和2.980(95%CI:1.128~7.871),均P<0.05。ADRB2 Gln27Glu基因多态性对MACE没有显著影响,相对危险度为1.408(95%CI:0.650~3.053),P>0.05。结论:ADRB2 Gln27Glu基因多态性与PCI术后接受β受体阻滞剂治疗患者的临床疗效无明显相关性。
AIM: To explore the β2 -adrenergie receptor (ADRB2) Gln27Glu genetic polymorphism in patients receiving β -blocker therapy after pereutaneous coronary intervention. METHODS: ADRB2 Gln27Glu genotypes were measured by TaqMan genotyping technique in 384 patients receiving β - blocker after percutaneous coronary intervention from Guangdong General Hospital. RESULTS: Genotype frequencies accorded with Hardy - Weinberg equilibium (P 〉 0.05 ). There was no significant differenee in clinical characteristics among different genotypes (P 〉 0.05 ) and neither was there in the kinds of β - blockers. Cox proportional hazards model demonstrated left main disease, diabetes and hypertension were strongly related with major adverse cardiac events (MACE) [ relative risk (RR) :2. 661 (95 % CI: 1. 122 - 6. 307), 2.431 (95% CI: 1. 127 - 5. 242 ) and 2.98 ( 95 % CI: 1. 128 - 7.871 ), respectively; all P 〈 0. 05 ]. ADRB2 Gln27Glu genetic polymorphism was not related to MACE ( RR: 1. 408, 95% CI : 0.650 - 3. 053, P 〉 0.05). CONCLU- SION: ADRB2 Gln27Glu genetic polymorphism was not related to the clinical effect of β -blocker therapy after percutane- ous coronary intervention.
