IntroductionJapanese guidelines recommend aspirin 160-300 mg/day, starting within 48 h, for patients with acute cerebral infarction. However, there are few reports evaluated in Japanese patients. Our objective was to examine the safety and efficacy of enteric-coated aspirin, compared with other oral antiplatelet drugs, in Japanese patients with acute ischemic stroke.MethodsWe performed a prospective, non-randomized, observational and multicenter study between June 2005 and December 2007. Patients with symptomatic acute ischemic stroke, including transient ischemic attack (TIA), who started enteric-coated aspirin or other antiplatelet drugs within 7 days of hospitalization were registered. Outcome measures evaluated within 3 months were incidence of cerebral and non-cerebral hemorrhagic events, recurrence of ischemic stroke or TIA, non-cerebral ischemic events and death from any cause.ResultsOverall, 2,548 and 830 patients treated with enteric-coated aspirin (100-300 mg/day) or other antiplatelet drugs, respectively, were registered; approximately 60% were male, mean age was 70 years, 85% had pre-existing cardiovascular disease or other complications. Enteric-coated aspirin of 100 mg was mainly prescribed, and only approximately half of the patients were started on it within 48 h after onset of ischemic stroke. Safety and efficacy population excluded patients without follow-up data were 2,521 in enteric-coated aspirin and 807 in other antiplatelets. Hemorrhagic events occurred in 46 (1.8%) in the enteric-coated aspirin group and in 13 (1.6%) in the other antiplatelet drugs group, there was not significant. Recurrent ischemic stroke or TIA occurred in 39 (1.5%) of the enteric-coated aspirin and in 18 (2.2%) of other antiplatelet drugs, and there were any-cause death in 16 (0.6%) and 8 (1.0%). Incidences were slightly lower in the enteric-coated aspirin group compared with the other antiplatelet drugs group, but not statistically significant.ConclusionIt seems that these results showed the safety and efficacy of the enteric-coated aspirin in acute stroke care in Japanese patients. Incidence of hemorrhagic events was comparable between the enteric-coated aspirin group and the other antiplatelet drugs group.
