Medicines for Heart failure
A long-term condition in which the heart cannot pump blood around the body as well as it should, causing breathlessness, tiredness and fluid build-up — managed with proven medicines that relieve symptoms and, in many cases, improve survival.

Quick answer
What is Heart failure?
Heart failure does not mean the heart has stopped; it means it is not pumping as effectively as it should, so the body and lungs do not get the blood flow they need. Typical symptoms are breathlessness, tiredness, and swelling of the ankles or legs from fluid build-up.
- How it is treated: Treatment aims to relieve symptoms, keep people out of hospital and, where possible, help them live longer.
- Self-care: Weighing yourself regularly to catch fluid build-up early, limiting salt and excess fluid as advised, staying as active as able, stopping smoking and getting recommended vaccinations all help control symptoms and reduce hospital admissions.
- When to seek help: Sudden severe breathlessness, chest pain, fainting or rapid weight gain with worsening swelling needs urgent assessment — call 999 for severe breathlessness or chest pain.
What it is
Heart failure does not mean the heart has stopped; it means it is not pumping as effectively as it should, so the body and lungs do not get the blood flow they need. Typical symptoms are breathlessness, tiredness, and swelling of the ankles or legs from fluid build-up. It is often caused by a previous heart attack, long-standing high blood pressure, heart-valve disease or an abnormal rhythm. A key distinction guides treatment: in heart failure with reduced ejection fraction, the main pumping chamber is weakened and empties poorly, whereas in heart failure with preserved ejection fraction the chamber pumps reasonably but is stiff and fills poorly. An ultrasound scan of the heart (echocardiogram) and a blood test help confirm the diagnosis and which type it is.
How it is treated
Treatment aims to relieve symptoms, keep people out of hospital and, where possible, help them live longer. For reduced ejection fraction there is a well-established set of "foundation" medicines — often called the four pillars — that work together and are introduced and built up steadily under supervision, because as a group they improve survival as well as symptoms. Fluid overload is eased separately with a water tablet, which makes people feel better but does not change the long-term outlook. For preserved ejection fraction the evidence is narrower, but SGLT2 inhibitors are now recommended, alongside managing blood pressure, weight, rhythm and other conditions. Care is shared between GP and specialist heart-failure teams, with regular review of symptoms, weight, kidney function and blood salts.

When to get help
When to see a doctor
Sudden severe breathlessness, chest pain, fainting or rapid weight gain with worsening swelling needs urgent assessment — call 999 for severe breathlessness or chest pain. Gradually worsening symptoms, or a steady rise in your daily weight, should prompt early contact with your heart-failure team or GP.
Not sure how urgent it is? It is always OK to call NHS 111 for advice, day or night.
Answers
Heart failure: frequently asked questions
What medicines are used for heart failure?
For the common reduced-ejection-fraction type, the foundation medicines are an ACE inhibitor (or ARB, or the ARNI sacubitril-valsartan), a heart-failure beta-blocker, a mineralocorticoid-receptor antagonist such as spironolactone, and an SGLT2 inhibitor. Loop diuretics are added to control fluid, and ivabradine or digoxin are used in selected people.
What is the difference between reduced and preserved ejection fraction?
Ejection fraction is the proportion of blood the main pumping chamber squeezes out with each beat. In reduced ejection fraction the chamber is weakened and empties poorly; in preserved ejection fraction it pumps reasonably but is stiff and fills poorly. The distinction matters because the medicines proven to help differ between the two.
Why am I on so many heart tablets?
In reduced-ejection-fraction heart failure, several "foundation" medicines work in different ways and, taken together, do more to relieve symptoms and prolong life than any one alone. They are introduced and built up gradually so your body adjusts and your kidneys and blood salts can be monitored.
Does a water tablet treat the heart failure itself?
A loop diuretic clears excess fluid, which quickly eases breathlessness and swelling, but it does not by itself improve the underlying pump or the long-term outlook. That is why it is used alongside the foundation medicines rather than instead of them.
