OBJECTIVE: To evaluate the clinical effect and restenosis rate of antiplatelet therapy following peripheral artery angioplasty and stenting. METHODS: After successful placement of peripheral artery stents to 103 patients with peripheral arterial occlusive disease (PAOD) in were randomized assigned to 2 groups: antiplatelet therapy group receiving clopidogrel 75 mg plus aspirin 100 mg (n = 56) and control group (n = 47) receiving anticoagulation therapy low molecular weight heparin (LWMH) for 7 d plus long-term warfarin. The patients were followed up 1 day, and 1, 6, 12, and 18 months after the operation to undergo color Doppler ultrasonography, and examinations of blood routine, bleeding time, coagulation time, and ankle-brachial Index. The primary endpoint events included major bleeding rate, and composite rate of restenosis and reocclusion. The secondary endpoint events included cardiovascular events, death, and adverse drug reaction. RESULTS: There were no significant differences in the baseline data between these two groups. The thrombotic occlusion rate was 1.8% in the antiplatelet group and 0% in control group, and the restenosis rate was 14.3% in the antiplatelet group and 25.5% in control group (both P > 0.05). The bleeding complication rate of the antiplatelet group was 1.8%, significantly lower than that of the anticoagulation group (19.1%, P < 0.01). There were not significant differences in cardiovascular event rate and mortality 18 months after operation between these two groups. CONCLUSION:Antiplatelet therapy combined with clopidogrel plus aspirin is effective and safe in preventing restenosis following peripheral artery angioplasty and stenting.
