Condition

Heart Failure

When the heart cannot pump enough blood to meet the body's needs.

Heart failure does not mean the heart has stopped — it means it needs help to keep up.

What it is

Heart failure does NOT mean the heart has stopped. It means the heart muscle is weakened or stiff and cannot pump effectively. Many patients live full lives with the right medicines, devices, and lifestyle.

Symptoms

Elderly man propped on pillows breathless at night
Waking up gasping or needing extra pillows is a red flag.
  • Breathlessness — first on exertion, later at rest or while lying down
  • Swelling of feet, ankles, or abdomen
  • Fatigue and reduced exercise tolerance
  • Waking up gasping at night
  • Rapid weight gain from fluid retention

Risk factors

  • Previous heart attack
  • Long-standing hypertension
  • Diabetes
  • Valve disease
  • Excess alcohol
  • Viral infection of the heart (myocarditis)
  • Family history of cardiomyopathy

How it's diagnosed

Cardiologist performing an echocardiogram
An echocardiogram tells us how strong — or weak — the pump really is.
  • Echocardiogram (most important)
  • NT-proBNP blood test
  • ECG
  • Chest X-ray
  • Cardiac MRI in selected cases

Treatment options

Pill organiser, weighing scale and notes for heart failure self-care
Modern medicines plus daily weighing keep most patients out of hospital.
  • Four pillars of modern therapy: ARNI/ACE inhibitor, beta-blocker, MRA, SGLT2 inhibitor
  • Diuretics for fluid control
  • CRT or AICD device in selected patients
  • Treatment of the underlying cause (CAD, valve disease, BP)
  • Salt and fluid restriction, daily weight monitoring

FAQ

Questions patients ask us most

Is heart failure curable?+

In some cases — especially when caused by a treatable problem — heart function can fully recover. In most cases, it is managed like a chronic condition with excellent quality of life.

Why is daily weighing important?+

A sudden weight gain of more than 2 kg in 2–3 days usually means fluid is building up. Reporting this early prevents hospitalisation.
