Diagnosed with heart failure: now what?

Heart failure means the heart is not pumping or filling well enough for the body’s needs. It does not mean the heart has stopped. The condition can cause fluid to build up, which may lead to breathlessness, a cough, swollen ankles, or fatigue. The underlying reason may include high blood pressure, a heart rhythm problem, previous heart damage, or another condition. Your clinician may explain whether the heart’s pumping strength, relaxation, or both are affected.

The diagnosis usually combines your symptoms and examination with tests such as blood tests, an electrocardiogram, an echocardiogram, or chest imaging. The type of heart failure guides treatment, so ask what your results show.

Keep a written list of medicines, doses, and changes. Take medicines exactly as prescribed and ask before using over-the-counter pain medicines, supplements, or salt substitutes. Some treatments affect blood pressure, kidney function, or mineral levels, so follow the requested blood and urine checks.

Record changes in breathing, energy, ankle swelling, and ability to lie flat. Follow the fluid, salt, activity, and weight advice that suits your plan rather than making sudden restrictions yourself. A chronic disease review can bring these checks together. Related concerns may include [Hypertension] and [Atrial Fibrillation].

Call emergency services if severe breathlessness starts suddenly, you cannot speak comfortably because of breathing difficulty, you have chest pressure, fainting, new confusion, or blue-grey lips. Seek prompt medical advice for rapidly worsening swelling, a new irregular or racing heartbeat with dizziness, or a cough that is becoming worse with breathlessness. Use your clinician’s local emergency instructions and do not drive yourself when severely unwell.

Ask: What type of heart failure do I have? Which symptoms should I record? What should I do if swelling or breathlessness increases? Which medicines or supplements should I avoid? When are my next blood tests and review? Should I arrange a chronic disease review or cardiac rehabilitation?
