Beta-blockers reduce the risk of early death in ischemic stroke

Abstract

Objectives: Beta-blockers reduce mortality in patients after myocardial infarction. Experimental studies suggest that beta-blockers have also neuroprotective properties. The aim of this study was to assess if use of beta-blockers is associated with reduced risk of early death in ischemic stroke patients.

Materials and methods: Retrospective data analysis of 841 consecutive patients with acute ischemic stroke admitted to the stroke unit within 24 h after stroke onset.

Results: 10.6% of patients received beta-blockers during hospitalization. Thirty-day case fatality was significantly lower in patients treated with beta-blockers than in those not treated with beta-blockers (6.8% versus 19.0%, P < 0.01). After adjustment for other prognostic factors, the use of beta-blockers was associated with reduced risk of early death (relative hazard 0.37, 95% confidence interval 0.16-0.84) independently of age, stroke severity, fasting glucose, total cholesterol level and pneumonia. When patients who died of cardiovascular causes were excluded from the analysis, the use of beta-blocker was no longer significantly associated with risk of death (P = 0.12).

Conclusion: In a retrospective series the use of beta-blockers was associated with reduced risk of early death in patients with ischemic stroke.
