Melatonin and Cardiovascular Outcomes in Older Adults
Evidence-Based Recommendations
- The American Heart Association, American College of Cardiology, and American Geriatrics Society do not recommend melatonin as a therapy for secondary prevention of cardiovascular disease in older adults 1, 2, 3, 4.
- The American Geriatrics Society and American College of Cardiology prioritize minimizing polypharmacy in older adults, making deprescribing and reduction of unnecessary medications a top priority 1, 2, 5.
- Adding melatonin to an already complex medication regimen in older adults with cardiovascular disease contradicts evidence-based principles of minimizing polypharmacy without proven benefit 1, 2.
- The American Heart Association guidelines for secondary prevention in older adults with cardiovascular disease prioritize proven therapies, including blood pressure control, antiplatelet therapy, statins for lipid management, beta-blockers and ACE inhibitors post-myocardial infarction, and anticoagulation for atrial fibrillation 3, 4, 5.
- Blood pressure control has been shown to reduce fatal stroke by 39% and all-cause mortality by 21% in adults ≥80 years 3, 4.
Practical Considerations
- The American Geriatrics Society and American College of Cardiology recommend focusing on optimizing evidence-based cardiovascular medications that have demonstrated mortality and morbidity benefits in older adults 1, 2, 3, 4.
- Melatonin should not be prescribed for cardiovascular disease prevention or treatment in older adults, but may be considered for separate indications such as circadian sleep disorders or insomnia 1, 2.
- Substituting melatonin for proven cardiovascular therapies or adding it to complex medication regimens without clear indication should be avoided 1, 3, 5.
