摘 要: | 目的评价普罗布考预防经皮冠状动脉介入治疗(PCI)后再狭窄的作用。方法将准备行PCI的82例稳定型心绞痛患者随机分为普罗布考组(n=42)和普伐他汀组(n=40)。两组患者于术前4周开始服用普罗布考1 000 mg/d或普伐他汀40 mg/d。服药4周后行金属裸支架置入术。术后继续原剂量及方法服用药物至24周。出院后定期随访,术后24周复查冠状动脉造影。结果PCI后随访至24周,两组严重临床事件发生率(死亡、急性心肌梗死、卒中及紧急血运重建术)差异无统计学意义(P〉0.05)。复查冠状动脉造影结果显示普罗布考组再狭窄率(22.5%)低于普伐他汀组(36.8%,P〈0.05),普罗布考组管腔直径狭窄率及晚期管腔丢失指数(分别为23.25%±10.08%及0.25±0.41)均低于普伐他汀组(分别为34.76%±16.99%及0.42±0.68,P〈0.05),纯获得(2.11±1.02 mm)大于普伐他汀组(1.51±0.96 mm,P〈0.05)。而两组晚期管腔丢失比较则差异无统计学意义(P〉0.05)。结论PCI前4周应用普罗布考降低PCI后再狭窄率的作用优于普伐他汀。

Abstract: | Objective To evaluate the efficacy of probucol in comparison with pravastatin in the prevention of restenosis in patients with PCI.Methods A total of 82 patients with stable angina pectoris were randomly assigned to either 1000 mg/d of probucol(n=42) or 40 mg/d of pravastatin(n=40) therapy for 4 weeks before PCI.After 4 weeks of premedication,the two groups underwent bare metal stent(BMS) implantation.Probucol and pravastatin were continued until follow-up angiography performed at 24 weeks alter PC1. After discharge, monthly clinical follow-up and angiographic follow-up at 24 weeks were performed. Results By the end of the 24-week-follow-up, comparison of clinical end points ( death, AMI, stroke and emergency revascularization ) between the two groups showed no statistical differences (P 〉 0. 05 ). Repeat angiography performed 24 weeks after PCI, showed that the restenosis rate was 22.5% in the probucol group and 36. 8% in the pravastatin group ( P 〈 0. 05 ). The percentage of diameter stenosis (23.25% ±10.08% vs34.76% ±16.99%, P〈0.05) and the late loss index (0.25±0.41 vs 0. 42± 0. 68, P 〈 0. 05 ) in the probucol group were significantly lower than those in the pravastatin group. Net gain in the probueol group was greater than that in the pravastatin group (2. 11 ± 1.02 mm vs 1.51 ±0. 96 mm,P 〈 0. 05 ). However, late loss between the two groups had no significant difference (P 〉 0. 05 ). Conclusion Administration of probucol 4 weeks before PCI can reduce the rate of restenosis of BMS in a more extent when compared with pravastatin. |
