Meditation and Cardiovascular Risk Reduction: A Scientific Statement From the American Heart Association.

Area of Science:

• Cardiology
• Preventive Medicine
• Neuroscience

Background:

• Cardiovascular disease (CVD) remains a major global health concern despite advances in treatment.
• There is a need for accessible, cost-effective interventions for primary and secondary CVD prevention.
• Meditation has demonstrated potential benefits for cardiovascular health.

Purpose of the Study:

• To systematically review existing data on the benefits of meditation for cardiovascular risk.
• To assess the biological plausibility and evidence supporting meditation's role in CVD prevention.

Main Methods:

• Systematic review of scientific literature on meditation and cardiovascular risk factors.
• Evaluation of studies examining meditation's impact on stress response, smoking cessation, blood pressure, metabolic syndrome, endothelial function, and myocardial ischemia.

Main Results:

• Neurophysiological studies suggest meditation can induce long-lasting brain changes, supporting its biological plausibility for cardiovascular benefits.
• Evidence indicates potential positive effects on stress, blood pressure, and metabolic factors, though study quality and quantity are often modest.
• Meditation may be a viable, low-risk adjunct to traditional CVD risk reduction strategies.

Conclusions:

• Meditation shows promise as a complementary approach for cardiovascular risk reduction.
• Further rigorous research, including randomized controlled trials with long-term follow-up, is necessary to establish definitive benefits.
• Individuals interested in lifestyle modifications may consider meditation, acknowledging the need for more robust evidence.
