New Study Links Melatonin and Heart Failure
A recent study has found a connection between long-term prescribed melatonin use and an increased risk of heart failure. The research analyzed health records of tens of thousands of adults with chronic insomnia and showed that those taking melatonin for over a year had a higher chance of developing heart failure within five years compared to nonusers.
Study Findings
- People using melatonin for more than one year were more likely to be hospitalized for heart failure.
- Those individuals also showed a higher risk of death from any cause than those who did not use melatonin.
Expert Reactions
The American Heart Association announced the study results, but experts warn that the research has not yet been peer reviewed and advise against rushing to conclusions or making drastic changes in melatonin use.
The preliminary results seem to contradict previous research suggesting melatonin might benefit people with heart failure.
Sleep medicine specialists and cardiologists call for further investigation into the long-term effects of melatonin.
Context and Next Steps
The findings come from an abstract expected to be presented at the American Heart Association’s Scientific Sessions, a major conference focused on cardiovascular science and medicine. Reviews of products and recommendations related to melatonin remain unbiased and independently selected, with no immediate changes recommended.
Summary
While a new study links prolonged melatonin use to heart failure risks, experts emphasize caution and highlight the need for more research before changing current guidance.
