Abstract

One hundred patients with transient ischemic attacks, minor strokes, or residual ischemic neurologic deficits were enrolled in a double-blind, randomized study comparing the effects of aspirin plus vitamin E [0.4 g (400 IU)/d; n = 52] with aspirin alone (325 mg; n = 48). The patients received study medication for 2 y or until they reached a termination point. Preliminary results show a significant reduction in the incidence of ischemic events in patients in the vitamin E plus aspirin group compared with patients taking only aspirin. There was no significant difference in the incidence of hemorrhagic stroke although both patients who developed it were taking vitamin E. Platelet adhesion was also measured in a randomized subgroup of both study populations by using collagen III as the adhesive surface. There was a highly significant reduction in platelet adhesiveness in patients who were taking vitamin E plus aspirin compared with those taking aspirin only. Measurement of α-tocopherol concentrations confirmed compliance of the patients with the medication schedule, showing a near doubling of serum concentrations of α-tocopherol. We concluded that the combination of vitamin E and a platelet antiaggregating agent (eg, aspirin) significantly enhances the efficacy of the preventive treatment regimen in patients with transient ischemic attacks and other ischemic cerebrovascular problems.
