Understanding congestive heart failure

Heart failure can result from a heart that squeezes weakly, relaxes poorly, or is affected by valve or rhythm disease. Reduced forward flow may cause fatigue and breathlessness. Pressure behind the heart can move fluid into the lungs or tissues, leading to a cough or swollen ankles. The word congestive refers to this fluid congestion; it does not mean the heart has stopped.

Symptoms vary with activity and may build gradually. A clinician combines your history and examination with tests such as an electrocardiogram, echocardiogram, blood tests and chest imaging when appropriate. Hypertension and atrial fibrillation are common conditions that may be relevant to the assessment.

Take prescribed medicines consistently and keep follow-up appointments so symptoms, blood pressure, kidney function and treatment effects can be reviewed. Note changes in breathlessness, sleep position, weight trend if your clinician has asked you to monitor it, swelling and energy. Follow individual advice about salt, fluids, exercise and vaccinations rather than copying another person’s plan.

A Chronic Disease Review can help coordinate medication questions and an action plan. Do not stop a heart medicine suddenly unless a clinician tells you to do so.

Emergency help is needed for severe breathlessness, chest pain, fainting, blue lips, sudden confusion or a rapid heartbeat with collapse. Contact your care team promptly if breathlessness is worsening, swelling increases, a cough becomes troublesome when lying down, or ordinary activity suddenly feels much harder.

Which type of heart failure do I have? What do my tests show? What changes should I monitor at home? How should I take my medicines if I am unwell? What is the plan if breathlessness or swelling increases?
