Heart failure therapy: what to expect

Treatment aims to reduce strain on the heart, ease congestion, control blood pressure and rhythm, and help you remain active safely. Your clinician may use more than one medicine, with doses adjusted according to symptoms, kidney function, blood pressure, and blood tests. Diuretics can help remove excess fluid; other medicines can influence the heart’s workload or protect it from harmful pressure. Treatment differs when the heart squeezes weakly from when it remains stiff but squeezes normally. Heart failure may coexist with Hypertension or Atrial Fibrillation, which also need attention.

Take medicines at the agreed times and keep a current list, including non-prescription products. Ask before using anti-inflammatory pain medicines, salt substitutes, or supplements because some can affect fluid balance, blood pressure, or kidney function. Track changes in breathlessness, ankle swelling, energy, and exercise ability. Attend blood tests and follow-up visits, where treatment can be reviewed. A Chronic Disease Review can help bring medication checks, monitoring and self-management advice together. Gradual activity suited to your condition is often discussed with the care team.

Get emergency help for severe breathlessness at rest, chest pain, collapse, new confusion, or blue lips. Contact your care team promptly for rapidly increasing swelling, a sudden change in breathing, faintness, or palpitations with weakness. Do not double a missed dose or stop treatment suddenly unless a clinician tells you to.

What is each medicine intended to do? How will you check whether the dose is suitable? Which side effects should I report? What should I do if vomiting, diarrhoea, or poor appetite makes medicines difficult to take?
