New Study Links Melatonin and Heart Failure
A recent study analyzed health records of tens of thousands of adults with chronic insomnia and found that those prescribed melatonin for over a year had a higher risk of heart failure within five years compared to nonusers, according to the American Heart Association’s announcement on Monday.
Study Findings
- People taking melatonin were more likely to be hospitalized for heart failure.
- They also had a higher risk of death from any cause compared to those not using the supplement.
Expert Reactions and Cautions
The study has not yet undergone peer review and has received mixed responses from sleep medicine specialists and cardiologists. Experts warn the public not to make sudden changes and emphasize the need for further research, especially concerning long-term melatonin use.
The American Heart Association said the preliminary findings contradict previous research indicating potential health benefits of melatonin for heart failure patients.
Context and Conference
The results come from a research abstract scheduled for presentation at the American Heart Association’s Scientific Sessions, a major conference on cardiovascular science and medicine.
