Among 2113 consecutive patients with first-ever ischemic stroke,125 patients had already been taking 100 to 500 mg of aspirin daily.Aspirin- treated and non-aspirin-treated patients did not differ in stroke severity.Mortality was lower in aspirin-treated patients(7.9%)than in non- aspirin-treated patients(12%),but this difference was not statistically significant(P=.17).We conclude that aspirin as primary prevention treatment has no significant protective effect on severity of first-ever ischemic stroke.The diminution of mortality after first ischemic stroke in patients who had used aspirin should be investigated further. |
