BACKGROUND: Millions of people around the world regularly consume aspirin, but its value in determining stroke severity is still not clear. It has been stated that prior aspirin use might reduce the severity of ischemic stroke by reducing the size of fibrin-platelet emboli or by ameliorating platelet hyperaggregability that occurs in the microcirculation. However there are only few large studies focusing on the early outcome of stroke patients including both ischemic stroke and primary intracerebral hemorrhage patients with prior aspirin therapy. REVIEW SUMMARY: We retrospectively analyzed the medical records of 2509 consecutive stroke patients who were hospitalized in the 2nd Neurology Clinic of Haydarpaşa Numune Education and Research Hospital, Istanbul, Turkey, during the period of 1993-2003. We compared the early mortality rates in the patients with prior aspirin use versus the patients without. Of the patients without prior aspirin use, 20.1% died during the first 3 weeks of the stroke, while only 11.5% of the patients with prior aspirin use died during the same period. The difference in early mortality rate between 2 groups was extremely significant (P = 0.0008). Logistic regression analysis indicated that aspirin use was a significant (P < 0.01) and independent predictor of early stroke mortality. CONCLUSION: Daily low dose (100-300 mg) aspirin has a protective effect in reducing the risk of early death in stroke.
