Trial Design

Study uses patients enrolled in WARSS, a randomized and double-blind secondary stroke and death prevention trial comparing aspirin and warfarin in two treatment arms. Antiphospholipid antibody status at baseline on all WARSS enrolled subjects. aPL status will also be documented yearly and at the time of a recurrent thrombo-occlusive event for all aPL(+) patients and one matched aPL(-) patient for each aPL(+) patient to ensure blinding of aPL status at each of the WARSS clinical centers.
