Why the study?

Whether different classes of antihypertensive drugs provide equal protection against stroke remains controversial.

Does the choice of specific antihypertensive drug class reduce stroke incidence in adults with hypertension?

Population

180,342 participants across 10 RCTs

Comparison

ACEIs, ARBs, BBs, CCBs, or diuretics vs another drug class or placebo

Design

Systematic review and meta-analysis of randomized controlled trials

Key result

Major antihypertensive drug classes showed no significant difference in overall stroke prevention (RR 0.94), as the magnitude of systolic blood pressure reduction was the primary determinant of benefit.

Overview

Prioritize SBP reduction over antihypertensive class for stroke prevention; reinforces BP lowering magnitude as the primary determinant.

Key Points

  • The review aims to systematically compare the effects of different antihypertensive drug classes on stroke prevention.
  • Conducted a systematic review following PRISMA guidelines.
  • Analyzed randomized controlled trials published since January 2000.
  • Compared different antihypertensive classes including ACEIs, ARBs, BBs, CCBs, and diuretics.
  • Used random-effects model for data pooling and conducted subgroup analyses.
  • No significant difference in stroke risk among drug classes with RR: 0.94; 95% CI: 0.83-1.05.
  • Substantial heterogeneity in results (I²=65%).
  • Moderate SBP differences (>2 mmHg) led to a significant stroke risk reduction (RR: 0.78; 95% CI: 0.71-0.85).
  • Minimal SBP differences (<2 mmHg) did not affect stroke risk (RR: 1.02; 95% CI: 0.90-1.14).
  • Overall, no drug class was superior for stroke prevention.

Main Result

Effect estimate: RR 0.94 (95% CI 0.83-1.05)

p-value: p=>0.05

The magnitude of achieved systolic blood pressure reduction, rather than the specific antihypertensive drug class used, is the primary determinant of stroke prevention in hypertensive patients.

Limitations

  • Considerable clinical and methodological heterogeneity among the included studies
  • Potential performance bias from PROBE designs or treatment strategy trials
  • Inclusion of fixed-dose combinations may confound the effect of a single drug class
  • Ecological fallacy risk due to reliance on study-level aggregate data for SBP differences
  • Inability to perform time-to-event analyses or adjust for patient-level covariates due to lack of individual patient data
  • Inability to analyze stroke outcomes by pathological subtype (ischemic vs. hemorrhagic)
  • Restriction to English-language publications
  • Substantial heterogeneity among included studies (I²=65%)
  • Risk of performance bias due to the inclusion of open-label or strategy trials

Shams et al. (2026) conducted a meta-analysis in Hypertension (n=180,342). Antihypertensive drug classes (ACEIs, ARBs, BBs, CCBs, diuretics) vs. Another antihypertensive drug class or placebo was evaluated on Fatal or non-fatal stroke incidence (RR 0.94, 95% CI 0.83-1.05, p=>0.05). Major antihypertensive drug classes showed no significant difference in overall stroke prevention (RR 0.94), as the magnitude of systolic blood pressure reduction was the primary determinant of benefit.
