|---|---|
| Main Objective: There is a two-phase objective of the trial. The aim of the first part of the study is a short-term evaluation of the patients symptoms and functional status (including a 6 minutes walk test) during treatment with CoQ10 and to monitor basic physiological parameters such as heart rate and blood pressure. The aim of the second part of the study is a long-term follow up to evaluate the effects on morbidity (unplanned cardiovascular hospitalisations) and mortality as a composite endpoint in patients with severe heart failure receiving optimal medical therapy. ;Secondary Objective: Serum samples for determination of N terminal pro brain natriuretic peptide (NT pro BNP) will be obtained at entry in the study and at follow-up to evaluate the hypothesis that CoQ10 may reduce the level of natriuretic peptides.;Primary end point(s): Physicians assessment a)New York Heart Association (NYHA) classification b)6 minutes hall walk distance (6MW) Levels of N terminal pro BNP at entry and after 16 weeks Major adverse cardiovascular events | — |
