Beta-Blockers for Preventing Stroke Recurrence
Description of Resource:
Beta-blockers are drugs that reduce heart rate and blood pressure, and have other effects that might also reduce the risks of stroke and heart attack. This systematic review sought to evaluate the efficacy of beta-blockers for preventing stroke recurrence and for reducing death and major vascular events in people with a previous stroke or transient ischemic attack (TIA), and to determine their safety. This review identified 2 high quality trials and found no clear evidence that beta-blockers reduced the risk of stroke, heart attack, or death from vascular disease. Participants who received beta-blockers instead of placebo showed significantly more adverse effects. More studies with larger samples are needed.
