For other outcomes analysed ( major vascular events , death from all causes , death from cardiovascular causes ) , we observed no significant differences between the groups .
There were minor blood pressure reductions in the intervention group .
To date , no available evidence supports the routine use of beta-blockers for secondary prevention after stroke or TIA .
BACKGROUND Stroke affects 15 million people per year worldwide .
Despite recent developments in acute stroke treatment , prevention remains very important .
Stroke has a high rate of recurrence ; therefore secondary prevention is also important .
Many clinical approaches to control risk factors have been proposed .
One of these approaches is the prescription of beta-blockers that have effects beyond the reduction of blood pressure , which can reduce the recurrence of stroke .
OBJECTIVES 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 ischaemic attack ( TIA ) , and to determine their safety , particularly with regard to the development of diabetes mellitus .
Beta-adrenergic blockade after stroke. A preliminary closed cohort study.
To collect background data for a prospect i ve clinical trial of beta-blocking agents in the prevention of deaths after stroke , the long-term prognosis in 60 patients discharged from a stroke unit on beta-blocker therapy  was compared with the outcome in 60 matched patients with stroke but without beta-blockers .  Matching included sex , age , type of stroke , and presence or absence of hypertension and cardiac failure . Thirteen patients ( 22 % ) in the beta-blocker group died during a median followup of 41 months . Of the 60 patients not on beta-blockade at discharge , 21 ( 35 % ) died during a median followup of 36 months . By life-table technique and log-rank test , the relative risk for death was 0.60:1.00 ( p = 0.14 ) . During followup , 12 recurrent strokes were observed in patients on beta-blockers and 19 in patients without beta-blockers ( relative risk 0.57:1.00 ; p = 0.12 ) . It appeared that the reduction in mortality could only marginally be ascribed to fewer deaths from myocardial infa rct ion ; other causes of death were also less frequent in beta-blocker-treated patients . The results emphasize that supplementary information on the effect of beta-blocking agents on mortality after stroke is needed before a larger trial of beta-blocker therapy in patients with manifest cerebrovascular disease can be initiated
