New Study Links Melatonin to Heart Failure
A recent study reviewing health records of tens of thousands of adults with chronic insomnia found that those who took prescribed melatonin for more than a year had an increased risk of heart failure over five years compared to nonusers, according to the American Heart Association.
Study Findings
- Melatonin users showed a higher likelihood of hospitalization for heart failure.
- These individuals also had a greater risk of death from any cause than those who did not use the supplement.
Expert Reactions
Sleep medicine specialists and cardiologists have expressed caution, emphasizing that the study has not yet undergone peer review and urging people not to make drastic changes based on these preliminary results.
Experts urge the public “not to panic” and call for further research into long-term melatonin use.
Context and Future Research
The findings contrast with previous research suggesting melatonin may benefit people with heart failure. The study's data comes from a research abstract expected to be presented at the American Heart Association’s Scientific Sessions, a major cardiovascular science conference.
