| Main Objective: Determination of the course of BNP (B-type natriuretic peptide) over 4 months of constant therapy and its correlation to other objective HF parameters (e.g. LVEF, NYHA-class, quality of life) in order to generate further efficacy data for the angiotensin II type I receptor blocker Candesartan Cilexetil in the treatment of heart failure when administered in an "added" regimen to standard HF therapy with at least ACE inhibitors. ;Secondary Objective: In addition the following secondary efficacy variables will be analysed: • Mean change from baseline (V1) to V6 for LVEF, NYHA-class, SF-36-score and NT-proBNP • Mean change from V4 to V6 for NYHA-class, BNP and NT-proBNP • Correlations of BNP with LVEF, NYHA classification, SF-36 score and NT-proBNP • Subgroup evaluation regarding beta-blocker therapy (yes/no) and NYHA classification (II / III) • Subgroup evaluation in terms of the different possible dosages of study medication during the 16 weeks of constant therapy (i.e. for 8, 16 or 32 mg Candesartan) ;Primary end point(s): Course of BNP (mean change from baseline (V1) to V6) | — |
