vitamin D, heart failure
Brief summary
The investigators hypothesized that in vitamin D deficiency the 25-OH-D3 vitamin substitution improve the heart function in chronic heart failure. Type of study: Controlled, randomized, double blind, placebo control Number of patient: 300; 150 treated and 150 placebo controlled Type of drug: 180 000 IU 25-OH-D3 vitamin oil (Vigantol) per month in the 0,1,2,3,6, month Duration of study:1+1 year Primary end points: Survival rate, Ejection fraction by ultrasound, Brain natriuretic peptid, Secondary end points: Safety of D-vitamin supplementation, well being score, blood pressure, BMI Walking distant in 6 minutes Visits: Screening, Randomization, 1month, 2 month, 3 month, 6 month, 12 month, 24 month,
Interventions
Vigantol oil, 9 ml, 180 000 IU at the 0,1,2,3,6 month (5 times in the study) MCT oil as placebo, 9 ml, 0,1,2,3,6 month (5 times in the study)
