Vitamin D to improve chronic heart failure symptoms
Part of Heart & circulation clinical trials.
This trial studies whether adding vitamin D can help people with chronic heart failure who have low vitamin D levels. You may be eligible if your heart’s pumping strength is reduced and your treatment has been stable, and you meet certain risk factors.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Your heart pumping function is reduced (left ventricular systolic dysfunction) with LVEF under 50%
- Your usual heart failure medicines and devices have been stable for more than 3 months
- Your vitamin D level is low (25-OH vitamin D3 under 50 nmol/L)
- You have at least one additional heart-failure risk factor, such as recent hospitalization, needing high-dose water pills, diabetes, or heart disease caused by poor blood supply
- You can and are willing to sign consent, and you do not have certain serious conditions (like active tuberculosis/sarcoidosis)

This trial checks if measuring vitamin D in dialysis patients can lead to better treatment, then gives vitamin D supplements to those who are low. It may help improve your bone and heart health.
This trial tests whether vitamin D supplements can help people with pulmonary arterial hypertension (high blood pressure in the lungs) who also have very low vitamin D levels. Participants will receive vitamin D or a placebo to see if it improves their condition.
This trial tests whether nutritional supplements can improve outcomes for people with heart failure. It aims to find an easy-to-follow, practical way to help manage the condition.
This trial tests whether giving a high dose of vitamin D3 can reduce death within 28 days for critically ill adults in the ICU who have very low vitamin D levels. It may help by correcting vitamin D deficiency, which the study team thinks could affect outcomes in serious illness.
This trial tests two forms of vitamin D (cholecalciferol and calcifediol) to see which better raises vitamin D levels in people with a deficiency. It may help you if your vitamin D is low, but you don't have osteoporosis or liver/kidney problems.
This trial tests if taking vitamin D can help people with bronchiectasis have fewer flare-ups. It is only for patients who were in an earlier study that checked their vitamin D levels.
