Condition heart failure
Treatments placebo, forceval plus 50 micrograms vitamin d3
Phase phase 2/phase 3
Sponsor Belfast Health and Social Care Trust
Start date February 2009
End date August 2013
Trial size 79 participants
Trial identifier NCT01005303, RGHT000395


There is some evidence to suggest that patients with heart failure may have a reduced dietary intake of vitamins and essential minerals (micronutrients) and that this may worsen the function of the heart. This study is designed to investigate if supplementation with micronutrients (including high−dose vitamin D) will improve the function of the heart in patients with heart failure.
