Heart Failure

Heart failure (HF), also known as congestive heart failure (CHF), is a syndrome characterized by the heart's inability to pump blood effectively to meet the body's needs. This results in symptoms such as shortness of breath, fatigue, and swollen legs. HF can be caused by various conditions, including heart attacks, high blood pressure, and infections.

Signs and Symptoms

Symptoms of heart failure are often categorized based on which side of the heart is affected. Common symptoms include shortness of breath, excessive fatigue, and swelling of the legs.

Left-Sided Heart Failure

The left side of the heart pumps oxygen-rich blood from the lungs to the rest of the body. Failure here leads to blood backing up into the lungs, causing respiratory symptoms like increased respiratory rate, laboured breathing, and pulmonary oedema. Other signs include a displaced apex beat and a gallop rhythm. Patients may also experience orthopnea (difficulty breathing while lying down) and paroxysmal nocturnal dyspnea (sudden nighttime shortness of breath).

Right-Sided Heart Failure

Right-sided heart failure, often caused by pulmonary hypertension or pulmonic stenosis, results in fluid accumulation in the body's tissues, leading to peripheral oedema, ascites, and liver enlargement. Jugular venous pressure is often elevated.

Severe peripheral pitting oedema

Biventricular Failure

In biventricular failure, both sides of the heart are affected, leading to symptoms of both left and right heart failure, including pleural effusion.

Signs and symptoms of severe heart failure


Heart failure can result from various conditions that alter the heart's structure or function. Common causes include:

  • Coronary artery disease
  • Heart attack
  • High blood pressure
  • Atrial fibrillation
  • Valvular heart disease
  • Excessive alcohol consumption
  • Cardiomyopathy


Diagnosis involves assessing symptoms, physical findings, and using diagnostic tools such as echocardiography, blood tests, and chest X-rays.


An echocardiogram is commonly used to evaluate heart function, determine ejection fraction, and identify structural abnormalities.

Chest X-ray

Chest X-rays can show cardiomegaly and signs of pulmonary oedema, such as Kerley B lines.

Blood Tests

N-terminal pro-BNP (NT-proBNP) and brain natriuretic peptide (BNP) levels are biomarkers used to diagnose heart failure.


Treatment focuses on improving symptoms and preventing disease progression. Management strategies include lifestyle changes, medications, and sometimes device therapy or surgery.

Lifestyle Changes

Patients are advised to stop smoking, engage in physical exercise, and follow a heart-healthy diet. Fluid and salt intake may need to be restricted.


First-line medications include:

  • Diuretics: To reduce fluid retention.
  • ACE inhibitors/ARBs: To lower blood pressure and decrease heart workload.
  • Beta blockers: To slow heart rate and reduce blood pressure.
  • Mineralocorticoid receptor antagonists: For further blood pressure control.
  • SGLT2 inhibitors: For patients with reduced ejection fraction.

Devices and Surgery

In severe cases, implanted devices such as pacemakers or implantable cardiac defibrillators may be recommended. In advanced heart failure, ventricular assist devices or heart transplantation may be necessary.

Palliative Care

For end-stage heart failure, palliative care focuses on symptom management and quality of life.

Heart failure is a complex condition requiring comprehensive management to improve patient outcomes and quality of life. Early diagnosis and intervention are critical for managing symptoms and slowing disease progression.
