Abstract

Background and purpose

We aimed to investigate the association of statin treatment with outcomes in patients with acute ischemic stroke.

Methods

Over a 4.5-year period (starting November 2007), 12 781 patients (mean age, 72·8 ± 12·6 years; 48·6% women) with acute ischemic stroke from 15 hospitals in Schleswig-Holstein, Germany, were enrolled in a population-based study and prospectively evaluated.

The primary outcomes were the mortality during hospitalization and the disability (modified Rankin Scale score ≥2) at discharge from hospital. The secondary outcomes were the mortality and disability at three-months after discharge.

Results

A total of 7535 patients (59%) with acute ischemic stroke were treated with statins. During hospitalization (mean, nine-days), the in-hospital mortality rate (4·7%; 95% confidence interval, 4·3–5·1%) was lower in patients treated with statins than in those without statins (2·3% vs. 7·9%, respectively; P < 0·001). At three-months after discharge, the mortality rate (6·9%; 95% confidence interval, 6·4–7·5%) was lower in patients treated with statins than in those without statins (5·0% vs. 10·6%, respectively; P < 0·001). Adjusted logistic regression analysis showed that statin treatment was associated with reduced rates of in-hospital mortality (odds ratio, 0·39; 95% confidence interval, 0·31–0·48; P < 0·001) and three-month mortality (odds ratio, 0.47; 95% confidence interval, 0·34–0·63; P < 0·001). A comparison of the patient groups revealed that patients on statins were likely to have lower disability rates at discharge (59% vs. 67%, respectively; P < 0·001) and after three-months (33% vs. 42%, respectively; P < 0·001) in patients who had survived the stroke.

Conclusion

Statin treatment may improve the outcomes in patients with acute ischemic stroke. Further studies are necessary to confirm this finding.
