Definition
Rheumatic Heart Disease (RHD) is a chronic heart condition that occurs as a result of rheumatic fever, an autoimmune inflammatory response to Group A beta-hemolytic streptococcal (GABHS) infection.
Causes
1. *Group A beta-hemolytic streptococcal (GABHS) infection*: Untreated or inadequately treated streptococcal infections, such as strep throat.
2. *Autoimmune response*: The immune system mistakenly attacks the heart valves, leading to inflammation and scarring.
Risk Factors
1. *Age*: Typically affects children and adolescents between 5-15 years old.
2. *Poverty*: Increased risk in developing countries due to poor access to healthcare.
3. *Family history*: Increased risk if there's a family history of RHD.
4. *Previous streptococcal infections*: Increased risk if previous infections were untreated or inadequately treated.
Pathophysiology
1. *Inflammation*: The autoimmune response causes inflammation in the heart, leading to scarring and damage to the heart valves.
2. *Valvular damage*: The mitral valve is most commonly affected, leading to mitral stenosis or regurgitation.
Signs and Symptoms
1. *Fever*: Low-grade fever.
2. *Fatigue*: Feeling weak or tired.
3. *Shortness of breath*: Difficulty breathing, especially during exercise.
4. *Chest pain*: Pain or discomfort in the chest.
5. *Palpitations*: Irregular heartbeats.
6. *Swollen legs and feet*: Fluid accumulation due to heart failure.
Medical Management
1. *Antibiotics*: Long-term antibiotic therapy to prevent recurrent streptococcal infections.
2. *Anti-inflammatory medications*: To reduce inflammation and scarring.
3. *Heart failure management*: Medications to manage heart failure symptoms.
Surgical Management
1. *Valve repair or replacement*: Surgery to repair or replace damaged heart valves.
2. *Mitral valve repair*: Surgery to repair the mitral valve.
Complications
1. *Heart failure*: Increased risk of heart failure due to valvular damage.
2. *Atrial fibrillation*: Increased risk of atrial fibrillation due to valvular damage.
3. *Stroke*: Increased risk of stroke due to atrial fibrillation.
4. *Endocarditis*: Increased risk of endocarditis due to valvular damage.
Nursing Management
1. *Monitor for signs of heart failure*: Closely monitor patients for signs of heart failure, such as shortness of breath or swollen legs and feet.
2. *Administer antibiotics*: Administer antibiotics as prescribed to prevent recurrent streptococcal infections.
3. *Provide education*: Educate patients and families on the importance of antibiotic adherence and follow-up care.
4. *Support physical activity*: Encourage patients to engage in regular physical activity to maintain cardiovascular health.
Nursing Diagnosis
1. *Activity intolerance*: Related to fatigue and shortness of breath.
2. *Anxiety*: Related to uncertainty and fear about the disease and its complications.
3. *Deficient knowledge*: Related to lack of understanding about the disease, its management, and prevention.
4. *Risk for complications*: Related to increased risk of heart failure, atrial fibrillation, stroke, and endocarditis.
