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
