For many years, patients with heart failure were told to rest and avoid physical exertion. We now know that this was incorrect. While rest is important during a flare-up, long-term inactivity causes your muscles to waste away, making you feel even more tired and breathless. Physical activity is a essential part of your treatment. It helps your muscles become more efficient at using oxygen, which takes the pressure off your heart. In the UK, structured support is available to help you move safely, ensuring you gain the benefits of exercise without overstretching your heart’s capacity. 

What We’ll Discuss in This Article 

  • Why exercise is a ‘medicine’ for a failing heart 
  • The difference between aerobic activity and resistance training 
  • Understanding the Borg Scale: How to monitor your intensity 
  • The availability and structure of NHS Cardiac Rehabilitation 
  • Pacing and safety: The ‘Talk Test’ for daily activities 
  • Spiritual and mental benefits of staying active 
  • Red-flag symptoms that mean you should stop exercising 

Recommended Types of Activity 

A balanced exercise programme for heart failure focuses on two areas: endurance and strength. 

1. Aerobic Exercise (Endurance) 

This includes activities like walking, cycling on a flat surface, or swimming. 

  • The Goal: To improve the efficiency of your heart and lungs. 
  • The Routine: Aim for a steady, rhythmic pace. Walking is the most accessible form of aerobic exercise for heart failure patients. 

2. Resistance Training (Strength) 

This involves light weights or using your own body weight (like rising from a chair). 

  • The Goal: To keep your leg and arm muscles strong. 
  • The Benefit: Stronger muscles mean you can perform daily tasks, like carrying groceries, with less effort from your heart. 

Monitoring Your Effort: The Borg Scale 

In heart failure, we do not use â€˜no pain, no gain.’ Instead, we use the Borg Scale of Perceived Exertion. 

  • The Safe Zone: Aim for a level of 3 or 4 (Moderate). 
  • The Feeling: You should feel slightly warm and be breathing deeper than usual. 
  • The ‘Talk Test’: You should be able to carry on a conversation. If you are too breathless to speak, you must slow down, you have exceeded your limit. 
Borg Score Intensity Noble Guidance 
0–2 Very Light Good for warming up. 
3–4 Moderate This is the ideal training zone. 
5–6 Hard Too intense; slow your pace. 
7–10 Very Hard Stop immediately and rest. 

NHS Cardiac Rehabilitation 

Cardiac rehab is an evidence-based programme designed to help you recover after a heart failure diagnosis or surgery. 

Is it available? 

Yes. NICE guidelines state that all heart failure patients should be offered a supervised exercise-based rehabilitation programme. If you haven’t been referred, you should ask your heart failure nurse or GP. 

What to expect: 

  • Assessment: A specialist therapist will check your fitness and your Ejection Fraction. 
  • Structure: Usually 6 to 12 weeks of sessions. 
  • Education: Sessions often include talks on diet, medication, and stress management. 
  • Multidisciplinary Team: You will be supported by nurses, physiotherapists, and dietitians. 

Spiritual and Mental Benefits 

Staying active is not just about the physical pump; it is about the health of the soul. holy Prophet Muhammad emphasized the importance of a strong and healthy believer. By engaging in a regular exercise programme, you are fulfilling the duty of caring for the body you have been given as a trust (Amanah). Many patients find that walking in nature or attending a rehab group reduces the anxiety and low mood that often accompany heart failure, providing a sense of community and peace. 

Conclusion 

Exercise is a powerful tool in your heart failure toolkit. By combining aerobic activities like walking with light resistance training, you can improve your quality of life and reduce your symptoms. The key is to start slow, use the Borg Scale to stay in the safe zone, and take advantage of the specialist support offered through NHS Cardiac Rehabilitation. Physical activity is not about running a marathon; it is about keeping your body strong and your heart stable so you can enjoy the moments of your daily life. 

Emergency Guidance 

If you experience heavy chest pain, dizziness, or a sudden â€˜thumping’ in your chest while exercising, stop immediately. If these symptoms do not settle within a few minutes of rest, call 999. It is to be cautious and seek expert medical assistance if your heart feels distressed. 

Can I exercise if I have a pacemaker or ICD? 

Yes. Most people with devices can exercise safely. However, you should avoid contact sports that might damage the device and ensure you have a ‘device check’ regularly. 

What if it is very cold or hot outside? 

Extreme temperatures put extra strain on the heart. On very cold days, it is to exercise indoors or wear a scarf over your mouth to warm the air. 

Does the Quranic view on moderation apply to exercise? 

The Quran teaches moderation in all things. In exercise, this means avoiding the extreme of total idleness (which weakens you) and the extreme of over-exertion (which harms the heart). Pacing is the ‘middle path.’ 

How soon can I start exercising after leaving the hospital? 

You should wait for your two-week follow-up with your nurse. They will check your blood pressure and heart rate to ensure you are stable enough to begin a gentle walking programme. 

 Is swimming safe for heart failure? 

Swimming is excellent but can be intense. The water pressure and temperature changes can sometimes be challenging for the heart. Discuss this choice with your consultant before starting. 

Can I do cardiac rehab at home? 

Yes. Since the pandemic, many NHS trusts offer ‘home-based’ rehab using booklets, apps, or video calls if you cannot attend a hospital-based class. 

Why do I feel more tired the day after exercise? 

This is known as ‘delayed onset fatigue.’ It may be a sign that you did slightly too much. Try reducing the time or intensity of your next session until you find your heart’s sweet spot.
