Heart Failure: Causes, Symptoms, Stages, Treatment and Cost in India

Heart failure is a long-term condition in which the heart muscle cannot pump blood around the body as well as it should. It affects tens of millions of people worldwide and is one of the leading reasons for hospital admission in adults. In Africa and South Asia, heart failure often affects younger people than in Western countries, because of untreated high blood pressure, rheumatic heart disease and heart muscle diseases. The name sounds frightening, but heart failure does not mean the heart has stopped. With modern medicines, devices and procedures, many patients feel much better, live longer and return to active lives. Indian hospitals offer the full range of advanced heart failure care, from medical therapy to heart transplantation, at a much lower cost than in the West.

What is Heart Failure?

In heart failure, the heart either cannot contract strongly enough or cannot relax and fill properly. As a result, fluid builds up in the lungs and body, and organs do not receive enough oxygen. Doctors measure the pumping strength using the ejection fraction (EF) - the percentage of blood pumped out of the left ventricle with each beat (normal is roughly 55 to 70 percent).

Types of heart failure

• Heart failure with reduced ejection fraction (HFrEF) - EF 40 percent or less; the heart muscle is weak.
• Heart failure with mildly reduced ejection fraction (HFmrEF) - EF 41 to 49 percent.
• Heart failure with preserved ejection fraction (HFpEF) - EF 50 percent or more, but the heart is stiff and does not fill well; common in older people, women, and those with high blood pressure, diabetes and obesity.
• Right-sided heart failure - often due to lung disease or left-sided heart failure, causing leg and abdominal swelling.

Stages and classes

The American College of Cardiology / American Heart Association describe four stages: Stage A (at risk, such as high blood pressure or diabetes), Stage B (structural heart changes but no symptoms), Stage C (symptoms of heart failure) and Stage D (advanced heart failure needing specialised treatment). Symptoms are also graded by the NYHA classes I to IV, from no limitation of activity to symptoms even at rest.

Causes and Risk Factors

• Coronary artery disease and heart attack - the most common cause globally, very frequent in South Asians and in the Gulf region.
• High blood pressure - a leading cause of heart failure in sub-Saharan Africa.
• Heart valve disease - including rheumatic heart disease, which remains common in Africa, South Asia and parts of the Middle East and affects young adults.
• Cardiomyopathies - diseases of the heart muscle, including dilated cardiomyopathy and peripartum cardiomyopathy (heart failure around childbirth), which is reported to be relatively common in parts of Africa.
• Diabetes, obesity and kidney disease.
• Irregular heart rhythms such as atrial fibrillation.
• Infections and other conditions - viral myocarditis, HIV, Chagas disease, thyroid disorders and severe anaemia, including in sickle cell disease.
• Alcohol and drug use, and some cancer treatments.
• Congenital heart disease that was not repaired in childhood.

Symptoms of Heart Failure

• Shortness of breath during activity, at rest, or when lying flat
• Waking at night breathless or needing more pillows to sleep
• Swelling of the feet, ankles, legs or abdomen
• Fatigue, weakness and reduced ability to exercise
• Rapid weight gain over a few days due to fluid retention
• Persistent cough or wheezing
• Fast or irregular heartbeat (palpitations)
• Poor appetite, feeling full quickly and nausea

Call emergency services or go to hospital immediately if you have: severe breathlessness or coughing up pink, frothy sputum, chest pain, fainting, a very fast or irregular heartbeat with dizziness, or sudden confusion.

How is Heart Failure Diagnosed?

• Echocardiogram (ECHO) - the key test, showing the ejection fraction, heart chambers and valves.
• ECG - to look for previous heart attacks, rhythm problems and conduction delays.
• Blood tests - BNP or NT-proBNP (raised in heart failure), kidney function, electrolytes, blood count, thyroid and iron studies.
• Chest X-ray - to check heart size and fluid in the lungs.
• Coronary angiography or CT coronary angiography - to find blocked arteries.
• Cardiac MRI - to identify the cause of cardiomyopathy and the amount of scarring.
• Holter monitoring, exercise testing and right heart catheterisation in selected patients.

Treatment Options for Heart Failure

1. Medicines

For heart failure with reduced EF, guidelines recommend a combination of four groups of medicines, often called the "four pillars": ARNI (sacubitril/valsartan) or an ACE inhibitor/ARB, beta-blockers, mineralocorticoid receptor antagonists (such as spironolactone) and SGLT2 inhibitors (dapagliflozin or empagliflozin). Diuretics relieve fluid build-up. These medicines, carefully adjusted by a cardiologist, can improve symptoms, reduce hospital admissions and help people live longer. SGLT2 inhibitors are also beneficial in HFpEF.

2. Treating the cause

• Angioplasty and stenting or coronary artery bypass surgery (CABG) for blocked arteries.
• Valve repair or replacement for valve disease, including minimally invasive techniques and MitraClip transcatheter mitral valve repair for selected patients with a leaking mitral valve who are at high risk for open surgery.
• Ablation or rhythm control for atrial fibrillation.

3. Devices

• Cardiac resynchronisation therapy (CRT) - a special pacemaker that coordinates the pumping of both ventricles in patients with a weak heart and a wide QRS on ECG.
• Implantable cardioverter defibrillator (ICD) - protects against sudden cardiac death from dangerous heart rhythms. A combined device (CRT-D) is often used.
• Left ventricular assist device (LVAD) - a mechanical pump for advanced heart failure, used as a bridge to transplant or as long-term therapy.

4. Heart transplantation

For carefully selected patients with end-stage heart failure despite all other treatment, a heart transplant can offer excellent long-term results. In India, heart transplants depend on deceased (brain-dead) donors through the state and national organ allocation system, and allocation rules for foreign nationals apply, so waiting times can vary.

Living with Heart Failure

• Take your medicines exactly as prescribed and do not stop them when you feel better.
• Weigh yourself every morning; a gain of about 2 kg in 2 to 3 days can mean fluid build-up and needs a call to your doctor.
• Limit salt and follow any fluid restriction advised by your doctor.
• Stay active with regular walking or a supervised cardiac rehabilitation programme.
• Stop smoking and avoid alcohol.
• Get influenza and pneumococcal vaccines.
• Control blood pressure, diabetes and cholesterol.
• Avoid NSAID painkillers, which can worsen fluid retention.

Preventing heart failure starts with treating high blood pressure early, preventing and treating rheumatic fever with antibiotics, controlling diabetes and acting quickly on heart attacks.

Frequently Asked Questions

Can heart failure be cured?

Heart failure is usually a long-term condition, but in some cases, such as when it is caused by a treatable valve problem, blocked arteries, a rhythm problem or peripartum cardiomyopathy, heart function can improve significantly or even return to normal with treatment.

What is a normal ejection fraction?

A normal EF is roughly 55 to 70 percent. An EF of 40 percent or less indicates reduced pumping strength, but symptoms do not always match the number.

How long can someone live with heart failure?

This varies widely depending on the cause, severity and response to treatment. Modern medicines and devices have greatly improved survival, and many patients live for many years with good quality of life.

Who needs a CRT or ICD device?

Generally, patients whose EF remains 35 percent or less despite at least three months of optimal medicines. CRT is added when the ECG shows a specific conduction delay. Your electrophysiologist will decide.

How long do I need to stay in India for a CRT or ICD implant?

Usually about 7 to 10 days, including evaluation, the procedure (with 1 to 2 days in hospital) and a wound and device check before flying home.

Can a foreign patient get a heart transplant in India?

Yes, but heart transplants depend on deceased organ donation and are allocated according to government rules, which give priority to Indian citizens. Waiting times are therefore unpredictable, and your doctors will discuss alternatives such as an LVAD.

Is exercise safe with heart failure?

For most stable patients, regular moderate exercise is safe and beneficial. Start with a supervised cardiac rehabilitation programme and avoid heavy lifting unless your cardiologist approves.
