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 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.
Study Findings
- Long-term melatonin users showed increased likelihood of hospitalization due to heart failure.
- They also had a higher risk of death from any cause compared to those who did not use melatonin.
Expert Reactions
The study has not undergone peer review and has elicited mixed responses from sleep and cardiology specialists. Experts caution against panic and emphasize the need for further research on the effects of prolonged melatonin use.
The preliminary results appear to contradict prior research that suggested melatonin might benefit people with heart failure.
The findings were presented as a research abstract at the American Heart Association’s Scientific Sessions, a major conference on cardiovascular science and medicine.

Summary
This initial study raises concerns about long-term melatonin use and heart failure risk but requires more research before any clinical conclusions or changes in usage guidelines are made.
Author’s Summary: Early research suggests a link between extended melatonin use and heart failure, but experts advise caution until further studies confirm these findings.
