Itâs important to remember that regular, moderate exercise is recommended for people with heart failure as this helps reduce the workload on the heart. However, if you feel your energy levels are decreasing this may be an early sign that your heart failure is getting worse. Increasing fatigue can also suggest other medical problems such as anaemia or thyroid problems. You should inform your doctor or nurse as soon as possible.
