We studied the effects of \u03b1-tocopherol and \u03b2-carotene supplementation. The incidence and mortality of stroke were examined in 28 519 male cigarette smokers aged 50 to 69 years without history of stroke who participated in the Alpha-Tocopherol, Beta-Carotene Cancer Prevention Study (ATBC Study). The daily supplementation was 50 mg \u03b1-tocopherol, 20 mg \u03b2-carotene, both, or placebo. The median follow-up was 6.0 years. A total of 1057 men suffered from incident stroke: 85 men had subarachnoid hemorrhage; 112, intracerebral hemorrhage; 807, cerebral infarction; and 53, unspecified stroke. Deaths due to stroke within 3 months numbered 38, 50, 65, and 7, respectively (total 160). \u03b1-Tocopherol supplementation increased the risk of subarachnoid hemorrhage 50% (95% CI \u22123% to 132%,\n            <jats:italic>P<\/jats:italic>\n            =0.07) but decreased that of cerebral infarction 14% (95% CI \u221225% to \u22121%,\n            <jats:italic>P<\/jats:italic>\n            =0.03), whereas \u03b2-carotene supplementation increased the risk of intracerebral hemorrhage 62% (95% CI 10% to 136%,\n            <jats:italic>P<\/jats:italic>\n            =0.01). \u03b1-Tocopherol supplementation also increased the risk of fatal subarachnoid hemorrhage 181% (95% CI 37% to 479%,\n            <jats:italic>P<\/jats:italic>\n            =0.01). The overall net effects of either supplementation on the incidence and mortality from total stroke were nonsignificant. \u03b1-Tocopherol supplementation increases the risk of fatal hemorrhagic strokes but prevents cerebral infarction. The effects may be due to the antiplatelet actions of \u03b1-tocopherol. \u03b2-Carotene supplementation increases the risk of intracerebral hemorrhage, but no obvious mechanism is available.\n          <\/jats:p>","DOI":"10.1161\/01.atv.20.1.230","type":"journal-article","created":{"date-parts":[[2011,6,17]],"date-time":"2011-06-17T19:44:19Z","timestamp":1308339859000},"page":"230-235","source":"Crossref","is-referenced-by-count":137,"title":["Controlled Trial of \u03b1-Tocopherol and \u03b2-Carotene Supplements on Stroke Incidence and Mortality in Male Smokers"],"prefix":"10.1161","volume":"20","author":[{"given":"Jaana M.","family":"Leppa\u0308la\u0308","sequence":"first","affiliation":[{"name":"From the Department of Public Health (J.M.L., O.P.H.), University of Helsinki;
