- Abstract
Purpose: To investigate the blood pressure (BP)-lowering effects of statins by conducting a systematic review and meta-analysis of placebo-randomized controlled trials (RCTs)., Method: We conducted a meta-analysis of placebo RCTs reporting antihypertensive effects of statins therapy. We only included RCTs that did not allow for concomitant antihypertensive therapy, or clearly stated that antihypertensive therapy was fixed throughout the study period., Results: Our meta-analysis included 46 placebo RCTs, including 53 group comparisons and a total of 49,087 participants (24,589 participants in the statin groups and 24,498 participants in the placebo group). Subgroup analysis, based on use of concomitant antihypertensive, was performed. The meta-analysis showed that statin reduced systolic BP by - 1.6 mmHg (95% CI: - 2.50 to - 0.60), and diastolic BP by - 0.96 mmHg (95% CI: - 1.36 to - 0.56). Although the presence of concomitant antihypertensive therapy diluted the BP lowering effect of statins, it remained statistically significant and independent of the lipid-lowering activity. Furthermore, the BP -lowering effect of the statins was independent of the dose or type of statin (p > 0.05)., Conclusion: Our results strengthen the evidence for pleiotropic effects of statins on BP that are independent of their lipid-lowering activity, supporting their beneficial role in hypertensive patients with dyslipidemia.
