NCT00634296

Brief Summary

This study aims to compare effects of inspiratory muscle training added by aerobic training to aerobic training alone in heart failure patients with inspiratory muscle weakness. To do so, strength and endurance of inspiratory muscles, functional capacity, quality of life, heart rate variability and sleep apnea evaluations will be conducted in patients with heart failure.
