High intensity exercise or omega 3s which one reduces heart failure risk

A year of high-intensity interval training appeared to benefit obese middle-aged adults at a high risk of heart failure, but omega-3 fatty acid supplementation didn't have any effect on cardiac biomarkers measured. This was seen in a small, single-center, prospective study. Where the Authors said that One year of high-intensity interval training reduces adiposity but had no consistent effect on myocardial triglyceride content or visceral adiposity.

Fifty-six patients completed the 1-year study, with a compliance rate of 90% in the high-intensity interval training group and 92% in those assigned omega-3 Fatty Acid supplementation, however there is tremendous potential for omega-3 in heart failure prevention and treatment. The study acknowledged that high-dose omega-3 supplements have been found to lower triglyceride levels in people with severe hypertriglyceridemia, and hypothesized that high-intensity interval training alone or with omega-3 supplementation would improve fitness and biomarkers in people with stage acute heart failure.
