Warfarin and Antiplatelet Vascular Evaluation

Summary

The purpose of this study is to evaluate whether the addition of warfarin (a blood-thinning medication) to an antiplatelet therapy like aspirin is better than antiplatelet therapy alone (i.e. usual treatment) for the prevention of leg surgery, heart attacks, stroke and death in people with peripheral vascular disease.
