NCT ID NCT06694727
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
Heart failure is a serious condition with a poor outlook despite modern treatments. This large Danish trial will test whether two common supplements—coenzyme Q10 and selenium—can help. About 4,044 adults with heart failure will take either the supplements or placebos for 2-3 years. Researchers will track how many are hospitalized for heart failure or die from heart problems.
