The Effect of Calcium and Vitamin D in Patients With Heart Failure
A Phase 4 study testing Vitamin D in people with Heart Failure and Vitamin D Deficiency, run by Hvidovre University Hospital at 1 site in Denmark.
Trial summary
Previous studies have shown high proportions of vitamin D deficiency among elderly in Denmark. Vitamin D is important for muscular function. The investigators intend to examine if it is possible to improve cardiovascular function in patients with heart failure and vitamin D deficiency by supplementation with vitamin D.

About this study
Previous studies have shown high proportions of vitamin D deficiency among elderly in Denmark. Vitamin D is important for muscular function. The investigators intend to examine if it is possible to improve cardiovascular function in patients with heart failure and vitamin D deficiency by supplementation with vitamin D.
Read the detailed description
Heart failure (HF) is a major course of morbidity and mortality. The prevalence in the Danish population is 1-2% and for age 50 -75 years: 2-3% (1) . It has been estimated that there are currently 6.5 million HF patients in Europe and 5 million in the USA (2) . Lack of vitamin D has been linked to heart disease including ischemic heart disease, heart failure, and hypertension.(3) Vitamin D deficiency is prevalent in the elderly population. Calcium absorption, bone mineralization and muscle function may be impaired. Vitamin D receptors have also been demonstrated in skeletal as well as cardiac muscle(4) . Vitamin D and Parathyroid Hormone (PTH) are closely linked in the calcium metabolic system. In order to maintain serum calcium within range PTH and vitamin D acts together in response to changes in serum-calcium levels. 25(OH)D concentration also being an important factor determining the levels of PTH.(5) Decreasing vitamin D leads to increasing levels of PTH. Hyperparathyroidism in patients with kidney-disease has in numerous studies been linked to cardiovascular disease, left ventricle hypertrophy, and valvular calcification .(6) Aim: Intervention with vitamin D and calcium will improve patients' vitamin D levels and suppress PTH. Thus we hope to find an improved cardiac function and quality of life in the intervention-group.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Vitamin D in people with Heart Failure and Vitamin D Deficiency, run by Hvidovre University Hospital at 1 site in Denmark.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 3 Jun 2015. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Denmark. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Ejection fraction (time frame: 6 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00497900, which also lists 5 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Jun 2015.
