Abstract:
Aim: Treatment for patients with severe chronic heart failure (CHF) (NYHA III, ejection fraction (EF) 34 during exercise have been shown to be useful for mortability risk stratification in CHF. This analysis investigated the effects of 3 week's cardiac rehabilitation (CR) on exercise parameters and VE/VCO2 slope in CHF patients.
Materials And Methods
Data from 35 patients with CHF (age 68 ± 11 years, 3 female, EF 29 ± 7%, maximum oxygen uptake (VO2max) 10.8 ± 2.7 mL/min/kg, NYHA class III, all ischemic heart disease) on optimal medication who underwent CR including aerobic endurance training theraphy combined with low dose local muscle strength for 3 weeks were evaluated retrospectively using 6 -min walking test, echocardiography and exercise testing.Results
All patients showed improvement in NYHA class, improvement in 6-min walking distance (285 ± 113 m to 431 ± 120 m, P Conclusion
CET for 3 weeks in severe CHF is associated with reduced VE/VCO2-slope and improved exercise capacity. Longer and randomized studies are needed to evaluate the role of VE/VCO2-slope in mortality risk stratification during training in CHF. Keywords:
