AB  - OBJECTIVE: Supervised cardiac rehabilitation programs have been offered to 
      patients following myocardial infarct (MI), coronary artery bypass graft surgery 
      (CABG) and percutaneous coronary intervention (PCI) for many years. However, 
      limited information is available on the usefulness of rehabilitation programs in 
      chronic heart failure (CHF). The aim of our study was to evaluate the outcome of 
      supervised physical training on CHF patients by measuring both central and 
      peripheral factors. MATERIAL AND METHODS: This was a prospective randomized 
      study, including 43 patients with CHF, New York Heart Association (NYHA) class II 
      or III, mean age 68 years. After initial measurements of V02peak, 6 minute walk 
      distance, muscle strength, plasma levels of atrial natriuretic peptide (ANP) and 
      brain natriuretic peptide (BNP), echocardiogram, measurements of pulmonary 
      function and quality of life questionnaire, patients were randomized to either a 
      training group (n=21) or a control group (n=22). The training group had 
      supervised aerobic and resistance training program twice a week for five months. 
      After the training program was completed, all measurements were repeated in both 
      groups. RESULTS: No training related adverse events were reported. Significant 
      improvement was found between groups in the six minute walk test (+37.1 m vs. 
      +5.3 m, p=0.01), work load on the bicycle exercise test (+6.1W vs. +2.1 W, 
      p=0.03), time on the bicycle exercise test (+41 s vs +0 s, p=0.02) and quadriceps 
      muscle strength test (+2.8 kg vs +0.2 kg, 0.003). Quality of life factors that 
      reflect exercise tolerance and general health, improved significantly in the 
      training group compared to the control group. No other significant changes were 
      found between the two groups. CONCLUSION: Supervised physical training as used in 
      this study appears safe for CHF patients in NYHA class II or III. The improvement 
      in functional capacity observed in the training group seems to be related more to 
      increased muscle performance rather than central cardiovascular conditioning.
