How can I manage anxiety or low mood linked to heart failure? 

Living with heart failure is not just a physical challenge; it is a profound emotional journey. It is entirely normal to feel anxious about your future, frustrated by your physical limits, or low in mood after a hospital stay. In the UK, it is estimated that up to 40% of people with heart failure experience significant anxiety or depression. The stress on the mind can even affect the heart, as anxiety causes the body to release adrenaline, which makes the heart beat faster and work harder.¹ Managing your emotional well-being is not a ‘luxury’, it is a essential part of your medical treatment plan.

The Heart-Mind Connection 

The symptoms of heart failure and anxiety often overlap, which can create a cycle of worry. 

• The Overlap: Both anxiety and heart failure can cause breathlessness, a racing heart (palpitations), and a feeling of tightness in the chest. 

• The Cycle: You feel breathless due to heart failure, which triggers a panic attack, which makes the breathlessness worse. 

• The Solution: Learning to distinguish between the two. If your breathlessness improves with calm, deep breathing, it may be anxiety. If it only improves by sitting still or using your water tablets, it is likely your heart. 

Practical Strategies for Anxiety 

You can take noble, proactive steps to calm your nervous system and reduce the strain on your heart. 

1. Cardiac Rehabilitation 

This is often the most effective way to reduce anxiety. Being in a noble, supervised environment where you can exercise safely helps you learn what your body is capable of. It replaces fear with confidence. 

2. Pursed-Lip Breathing 

When you feel a wave of anxiety or breathlessness: 

• Breathe in slowly through your nose. 

• Pucker your lips as if you are about to whistle. 

• Breathe out twice as slowly through your pursed lips. 

• This technique slows your heart rate and signals to your brain that you are safe. 

3. The 5-4-3-2-1 Grounding Technique 

If your mind is racing with worries about the future, bring yourself back to the present: 

• Acknowledge 5 things you can see. 

• 4 things you can touch. 

• 3 things you can hear. 

• 2 things you can smell. 

• 1 thing you can taste. 

Managing Low Mood 

Low mood often stems from the grief of losing the life you had before your diagnosis. 

• Set SMART Goals: Instead of focusing on what you can’t do, set small, goals. ‘I will walk to the end of the garden today’ provides a sense of achievement. 

• Stay Connected: Isolation is a major trigger for depression. Even a short phone call with a friend can provide relief. 

• NHS Talking Therapies: In the UK, you can self-refer to NHS Talking Therapies (formerly IAPT). Cognitive Behavioural Therapy (CBT) is a effective tool for changing the negative thought patterns associated with chronic illness.⁵ 

The Role of Medication 

Sometimes, the chemical balance in the brain needs a helping hand. 

• Antidepressants (SSRIs): Certain antidepressants are very safe for heart failure patients and can actually improve long-term outcomes by reducing the constant stress on the heart. 

• Consultation: Always speak to your heart failure nurse before starting any new mental health medication, even herbal ones like St. John’s Wort, as they can interact with your heart tablets. 

Spiritual and Community Anchors 

For many, a sense of purpose and community is the best medicine for the mind. 

• The Perspective: In many spiritual traditions, including the views found in the Quran, the heart is seen as the centre of peace and remembrance.⁶ Engaging in prayer, meditation, or community service can provide a ‘tranquillity’ (Sakina) that lowers blood pressure and eases anxiety. 

• Support Groups: Joining a local ‘Pumping Marvellous’ group or a British Heart Foundation support circle allows you to share experiences with others who truly understand your journey. 

Conclusion 

Anxiety and low mood are challenges that come with heart failure, but they do not have to define your life. By using tools like cardiac rehab, breathing techniques, and talking therapies, you can break the cycle of fear and rediscover a sense of calm. Your mental health is a vital pillar of your heart health. Being honest with your medical team about how you feel allows them to provide the full, comprehensive support you deserve. Remember, a peaceful mind is one of the most gifts you can give to your heart. 

Emergency Guidance 

If your low mood leads to thoughts of self-harm, or if your anxiety is causing severe chest pain that does not settle with rest, call 999 or the NHS 111 mental health line (Option 2) immediately. These are emergencies that require instant expert care.
