Abstract:
Objective:To explore the relationship between the selection of different P2Y 12 inhibitors and the long-term prognosis of acute coronary syndrome (ACS) patients with and without CYP2C19 defect gene. Method:289 consecutive ACS patients who underwent percutaneous coronary intervention (PCI) at Tianjin Third Central Hospital from March 2016 to October 2016 were selected for CYP2C19 gene polymorphism detection. According to the detection results, the patients were divided into group A (with CYP2C19 loss-of-function gene, 199 cases) and group B (without CYP2C19 loss-of-function gene, 90 cases). After PCI, different P2Y 12 inhibitors were selected. The patients were followed up for 3 years, and 23 cases were lost to follow-up. Finally, 182 cases were enrolled in group A and 84 cases were enrolled in group B. According to whether there were major adverse cardiovascular events (MACE) within 3 years, the patients in groups A and B were divided into MACE subgroups (58 cases, 32 cases) and non-MACE subgroups (124 cases, 52 cases). The single factor analysis of the two subgroups in groups A and B was carried out based on the patient's clinical data, coronary artery disease and intervention status, and postoperative drug treatment plan. Risk factors with statistical significance ( P<0.05) were selected, and multivariate logistic regression analysis was performed on groups A and B to compare the effects of different P2Y 12 inhibitors on the prognosis of the two groups. Results:The differences in platelet volume, fasting blood glucose, HbA1c, left ventricular end-diastolic diameter, proportion of single-branch lesions, proportion of intervention for left main lesions, and dual antiplatelet therapy were statistically significant between the two subgroups in group A (all P<0.05). The differences in low-density lipoprotein (LDL), left ventricular ejection fraction (LVEF), left ventricular end-diastolic diameter, proportion of two-branch lesions, proportion of three-branch lesions, and proportion of using tirofeben were statistically significant between the two subgroups in group B (all P<0.05). In the group A, the choice of different P2Y 12 inhibitors was the independent risk factor for the long-term prognosis. Compared with patients treated with Ticagrelor, the probability of long-term MACE was 11.971 times larger ( OR=12.971, 95% CI: 5.028~33.464, P<0.001) among patients treated with Clopidogrel 75 mg/day, and 5.029 times larger ( OR=6.029, 95%CI: 2.278~15.958) among patients treated with Clopidogrel 100 mg/day. No significant correlation was witnessed between different P2Y 12 inhibitors and long-term prognosis in group B. In the group B, different P2Y 12 inhibitors have no significant correlation with their long-term prognosis of patients( P>0.05). Conclusions:For ACS patients with CYP2C19 loss-of-function gene, the choice of P2Y 12 inhibitors is associated with their long-term MACE events after PCI. Ticagrelor therapy brings the lowest risk of long-term MACE. For those without CYP2C19 loss-of-function gene, the correlation between the choice of different P2Y 12 inhibitors and their prognosis is not significant.
