Despite significant therapeutic improvements, congestive heart failure (CHF) patients still have a poor prognosis. Currently, 5-year survival rates are only 35-50%. There is an accumulating body of evidence from prospective cohort studies that low circulating 25-hydroxyvitamin D is an independent predictor of all-cause and cardiovascular mortality, respectively. Vitamin D deficiency is prevalent among CHF patients. We hypothesize that vitamin D may improve survival in CHF patients. We therefore aimed to investigate whether vitamin D supplementation reduces mortality and increases event-free survival in end-stage CHF patients.

Primary Outcome Measures:
  • Number of participants who died during the intervention [ Time Frame: three years ] [ Designated as safety issue: No ]
    all-cause mortality (any cause of death) will be assessed

Secondary Outcome Measures:
  • Number of event-free survivors [ Time Frame: three years ] [ Designated as safety issue: No ]
    event defined as: death from any course, cardiac transplantation, high urgent listing for cardiac transplantation, rescucitation, hospitalisation, ventricular assist device implantation

  • Changes in biochemical risk markers [ Time Frame: three years ] [ Designated as safety issue: No ]
    inflammation markers, kidney parameters, lipid parameters, haemostasis parameters

  • Number of participants with elevated safety parameters [ Time Frame: every 6 months ] [ Designated as safety issue: Yes ]

    Serum 25-Hydroxyvitamin D should not exceed 150 ng/ml.

    Serum calcium should not exceed 2.75 mmol/l.
