title: High-dose acetylsalicylic acid after cerebral infarction. A Swedish Cooperative Study.
abstract: Within 3 weeks of the event, 505 patients with cerebral infarction, minor or major stroke, were randomly assigned to treatment with acetylsalicylic acid (ASA) 1.5 g/day or placebo in a double-blind clinical trial with a follow-up of 2 years in all patients. Primary events were considered to be recurrent stroke or death; secondary events, myocardial infarction and transient ischemic attack. There was no difference in stroke recurrence rate in the ASA and placebo groups (12 and 13%, respectively), nor was there any significant difference in the rate of recurrent stroke or death, first event counted (23% in the ASA and 22% in the placebo group). The risk of transient ischemic attack and myocardial infarction was not reduced in the ASA group. In the present study there was no prophylactic effect of high-dose ASA after cerebral infarction. A compilation of the major trials of ASA after transient ischemic attack and cerebral infarction is presented.
