Statins As Anti-Hypertensive Therapy: A Systematic Review and Meta-Analysis

Area of Science:

• Cardiovascular Medicine
• Pharmacology

Background:

• Hypertension is a prevalent clinical condition, often coexisting with diabetes and hypercholesterolemia, major contributors to cardiovascular diseases.
• Statins are widely used for cardiovascular event reduction and have demonstrated lipid-lowering properties.
• Emerging evidence suggests statins may also reduce blood pressure in hypertensive individuals.

Purpose of the Study:

• To evaluate the effectiveness and efficacy of statins in managing hypertension.
• To determine the impact of statins on blood pressure control in patients with hypertension, particularly when used with antihypertensive medications.

Main Methods:

• A systematic search was conducted across major databases (PubMed, Science Direct, Embase, Cochrane Library, Google Scholar).
• Included studies were randomized controlled trials, meta-analyses, and cohort studies in English, involving adult hypertensive patients on statins.
• A total of 32 articles, including 25 randomized controlled trials and 7 meta-analyses from 9361 initially screened studies, were analyzed.

Main Results:

• Statins were found to be effective in reducing both systolic and diastolic blood pressure.
• Analysis utilized a heterogeneous model due to study variations, with I2 values indicating moderate heterogeneity for systolic and diastolic blood pressure.
• The meta-analyses included in the study also showed a significant role for statins in blood pressure management.

Conclusions:

• Statins demonstrate a beneficial role in reducing blood pressure in hypertensive patients.
• The findings support the use of statins as an adjunct therapy for hypertension management.
• Further research may explore the specific mechanisms by which statins influence blood pressure regulation.
