Long term melatonin use may signal heart problems

Long-term melatonin use may be a red flag for the heart, researchers report. Reviewing five years of records from 130,828 adults (average age 56), regular users for at least a year had higher rates of heart failure (4.6% vs 2.7%), hospitalization (19% vs 6.6%), and death. The team says melatonin isn’t proven to cause harm; instead, persistent insomnia may signal cardiac strain. Outside experts urged caution, noting over-the-counter use often isn’t captured in records. The findings, led by SUNY Downstate researcher Dr. Ekenedilichukwu Nnadi, will be presented at an American Heart Association meeting and have not been peer reviewed.
