RHEUMATIC HEART DISEASE

🚀INTRODUCTION

Rheumatic heart disease is a chronic heart condition caused by damage to the heart valves following Rheumatic Fever, which occurs after infection with Group A beta‑hemolytic Streptococcus.

It mainly affects the mitral valve and sometimes the aortic valve, leading to valve stenosis or regurgitation. Rheumatic heart disease is more common in children and young adults, especially in developing countries, and can lead to serious complications such as heart failure if not treated properly.

📚 DEFINITION

Rheumatic heart disease is a chronic condition characterized by permanent damage to the heart valves caused by rheumatic fever following infection with Group A beta‑hemolytic Streptococcus.

🔸 CAUSES

• Infection by Group A beta‑hemolytic Streptococcus

• Repeated attacks of Rheumatic Fever

• Untreated streptococcal throat infection

• Poor hygiene and overcrowding

• Low socioeconomic condition

  
  

📢 CLINICAL MANAGEMENT

• Shortness of breath (dyspnea)

• Fatigue / weakness

• Chest pain

• Palpitations (irregular heartbeat)

• Heart murmur

• Swelling of legs and feet (edema)

• Cough, sometimes with blood

• Dizziness or fainting

📈 PATHOPHYSIOLOGY

👨🏻‍🔬 DIAGNOSIS EVALUATION

• Echocardiography

• Electrocardiogram (ECG)

• Chest X-ray

• Blood test (ASO titre)

👨🏻‍⚕️ TREATMENT

1. Antibiotics – e.g., Penicillin to prevent streptococcal infection

2. Anti-inflammatory drugs – e.g., Aspirin or steroids

3. Diuretics – to reduce fluid overload

4. Anticoagulants – to prevent blood clots

5. Valve repair or valve replacement surgery in severe cases

🏥 HEALTH EDUCATION

1. Take regular antibiotics as prescribed (e.g., Penicillin).

2. Treat sore throat infections early.

3. Maintain good personal hygiene.

4. Take regular medical check-ups.

5. Follow balanced diet and adequate rest.

6. Avoid overexertion / heavy work.
