As an excellent source of heart-healthy omega-3 fatty acids, daily fish oil supplements are a popular way to keep the risk of cardiovascular disease at bay.
About 20% of adults older than age 60 in the United States frequently use these products with the aim of supporting heart health.
However, a new study finds regular use of fish oil supplements may increase, not reduce, the risk of first-time stroke and atrial fibrillation among people in good cardiovascular health.
For participants with a diagnosis of a known cardiovascular disease, regular use of fish oil supplements was beneficial for transitions from atrial fibrillation to major adverse cardiovascular events (hazard ratio 0.92, 0.87 to 0.98), atrial fibrillation to myocardial infarction (0.85, 0.76 to 0.96), and heart failure to death (0.91, 0.84 to 0.99).
These people were already sick with cardiovascular disease. I’d be interested in a peer review
