Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The central objective of this proposal is to establish that vitamin D supplementation in heart failure patients with low vitamin D levels will have improved outcomes compared to placebo. In addition the investigators will also evaluate the role of genetics in regard to vitamin D and heart failure. The investigators will be evaluating what is currently a novel approach of identifying patients with low vitamin D and treating this low vitamin D level. The investigators will be able to evaluate the importance of vitamin D supplementation in these patients and the role of genetics on our defined outcomes.
