Brief Summary

Heart failure is a common and serious condition. Despite rapid advancements in heart failure treatment, the prognosis remains severe. Smaller studies have shown that two simple, safe, and relatively inexpensive nutritional supplements-coenzyme Q10 and selenium-may reduce the risk of complications associated with heart failure. The DANUTRIO-HF trial will investigate whether these supplements can make a difference for individuals with heart failure. The study will assign approximately 4,044 patients from across Denmark to either coenzyme Q10 (100 mg twice daily) or a corresponding placebo, as well as selenium (100 μg twice daily) or its corresponding placebo, and follow how many of them end up being hospitalized for heart failure or dying from heart problems over an estimated two to three-year period.

Eligibility Criteria
