Why the study?
Does antihypertensive drug treatment reduce the incidence of stroke in patients with hypertension or a history of cerebrovascular disease?
Population
Patients with hypertension and patients with a history of cerebrovascular disease
Comparison
Antihypertensive drug treatment vs Old drugs (diuretics or beta-blockers)
Design
Meta-analysis
Key result
Angiotensin Type 1 receptor blockers reduced stroke incidence by 24% (p=0.0002) compared to diuretics or beta-blockers, and blood pressure-lowering therapy reduced stroke recurrence by 25%.

Favors ARBs over diuretics or beta-blockers for stroke prevention; confirms recurrence reduction and strengthens class-specific evidence.
Meta-Analysis
Does antihypertensive drug treatment reduce the incidence of stroke in patients with hypertension or a history of cerebrovascular disease?
Effect estimate: 24% reduction (ARBs)
p-value: p=0.0002
Antihypertensive therapy, particularly with ARBs and CCBs, significantly reduces the risk of primary and secondary stroke, largely driven by differences in systolic blood pressure reduction.
Wang et al. (2004) conducted a meta-analysis in Hypertension and history of cerebrovascular disease. Antihypertensive drug treatment (calcium-channel blockers, angiotensin Type 1 receptor blockers, ACE inhibitors) vs. Older drugs (diuretics or beta-blockers) was evaluated on Incidence of stroke (24% reduction (ARBs), p=0.0002). Angiotensin Type 1 receptor blockers reduced stroke incidence by 24% (p=0.0002) compared to diuretics or beta-blockers, and blood pressure-lowering therapy reduced stroke recurrence by 25%.
