Safety and effects of physical training in chronic heart failure. Results of the Chronic Heart Failure and Graded Exercise study (CHANGE)
Summary
This summary is machine-generated.Physical training is safe for chronic heart failure patients, improving exercise capacity and quality of life. This study confirms benefits for patients with moderate heart failure, enhancing key physiological markers.
Area Of Science
- Cardiology
- Exercise Physiology
- Rehabilitation Medicine
Background
- Heart failure management often includes physical activity, but large-scale studies are needed to confirm safety and efficacy.
- Endurance training is a potential therapeutic modality for improving functional capacity in patients with chronic heart failure.
Purpose Of The Study
- To evaluate the safety and efficacy of a physical training program in patients with chronic heart failure (CHF) class II and III.
- To assess the impact of endurance training on exercise tolerance, physiological parameters, and quality of life in CHF patients.
Main Methods
- A prospective randomized controlled trial involving 80 patients with CHF class II-III.
- Patients were assigned to either an endurance training group or a control group receiving optimal pharmacological treatment.
Main Results
- The training program was safe, with no reported adverse events.
- Significant improvements were observed in exercise time, anaerobic threshold, and ventilatory equivalent for carbon dioxide.
- Quality of life improved, with a correlation between physiological and psychological benefits. Peak oxygen consumption did not significantly increase.
Conclusions
- Physical training is a safe and beneficial intervention for patients with chronic heart failure class II and III.
- Endurance training leads to significant improvements in exercise capacity, key physiological markers, and quality of life.
- Training effectiveness may be influenced by baseline exercise test duration.
