Heart Failure

Heart failure is a condition in which the heart cannot pump enough blood to meet the body's needs. Blood and fluid may collect in the lungs and legs.

Common symptoms

  • Breathlessness, especially on walking or lying down
  • Tiredness and weakness
  • Swelling of feet, ankles, or abdomen
  • Cough, especially at night
  • Rapid weight gain due to fluid retention

Types of heart failure

  1. Left-sided heart failure
    • Left ventricle fails to pump effectively.
    • Blood backs up into the lungs.
    • Causes breathlessness, cough, and pulmonary edema.
  2. Right-sided heart failure
    • Right ventricle fails to pump effectively.
    • Blood backs up into the body veins.
    • Causes pedal edema, enlarged liver, abdominal swelling, and raised neck veins.
  3. Systolic heart failure (HFrEF)
    • Heart muscle contracts weakly.
    • Ejection fraction is reduced, usually 40% or less.
  4. Diastolic heart failure (HFpEF)
    • Heart contracts but becomes stiff and does not relax/fill properly.
    • Ejection fraction is preserved.
  5. Acute or chronic heart failure
    • Acute: sudden worsening, often severe breathlessness and lung congestion.
    • Chronic: long-term condition with repeated symptoms.

Management

1. General measures

  • Rest during severe symptoms, then regular light exercise as advised.
  • Reduce salt intake.
  • Limit fluids if advised by the doctor.
  • Daily body-weight check.
  • Stop smoking and avoid alcohol.
  • Treat the cause, such as hypertension, heart attack, valve disease, or anemia.

2. Medicines

  • Diuretics such as furosemide to reduce swelling and lung congestion.
  • ACE inhibitors/ARBs/ARNI to reduce workload on the heart.
  • Beta-blockers to improve heart function and survival.
  • SGLT2 inhibitors are also part of standard treatment for many patients with HFrEF.
  • Mineralocorticoid receptor antagonists such as spironolactone may be used.
For HFrEF, modern guideline-directed treatment includes four main medicine groups: ARNI/ACE inhibitor/ARB, evidence-based beta-blocker, mineralocorticoid receptor antagonist, and SGLT2 inhibitor, as summarized in the AHA heart-failure guideline.

3. Severe cases

  • Oxygen and intravenous diuretics in acute pulmonary edema.
  • Pacemaker/ICD or cardiac resynchronization therapy in selected patients.
  • Valve surgery, angioplasty, LV assist device, or heart transplant in advanced disease.
Emergency signs: severe sudden breathlessness, chest pain, fainting, confusion, or pink frothy sputum need urgent hospital care.

Chronic Heart Failure - Short Note (5 Marks)

Definition

Heart failure is a condition in which the heart cannot pump enough blood to meet the body’s needs. It causes breathlessness, fatigue, and fluid accumulation in lungs or body tissues.

Classification

  1. Left-sided heart failure
    Blood backs up into lungs causing breathlessness.
  2. Right-sided heart failure
    Blood backs up into body veins causing pedal edema and abdominal swelling.
  3. Systolic failure (HFrEF)
    Heart contraction is weak and ejection fraction is reduced.
  4. Diastolic failure (HFpEF)
    Heart is stiff and cannot relax/fill properly, but ejection fraction is usually normal.

Pathophysiology

Heart damage or long-standing hypertension causes reduced pumping.
↓ Cardiac output
→ kidneys retain salt and water
→ increased blood volume
→ fluid collects in lungs and legs
→ breathlessness and edema.

Symptoms and signs

  • Dyspnea on exertion and orthopnea
  • Fatigue, weakness
  • Cough, especially at night
  • Swelling of feet and ankles
  • Weight gain due to fluid retention
  • Raised JVP and enlarged liver in right-sided failure
Chronic heart failure is long-standing heart failure with persistent or repeated symptoms; it may worsen suddenly during infection, hypertension, arrhythmia, or missed medicines.
