I09.9

Clinical Causes: Previous streptococcal infection (strep throat or scarlet fever) Genetic susceptibility Immune response malfunction leading to inflammation Inadequate or delayed medical treatment for strep infections

Key Symptoms: Fatigue and weakness Shortness of breath, especially during physical activity or lying down Palpitations or irregular heartbeat Chest pain or discomfort Swelling in the legs, ankles, or abdomen Fainting or dizziness Subcutaneous nodules (small, painless lumps under the skin) Skin rash known as erythema marginatum

Diagnosis Path: Diagnosis of rheumatic heart disease typically involves a combination of medical history, physical examination, and diagnostic tests. Physicians may look for signs of heart inflammation, valve damage, and recent streptococcal infection. Common diagnostic procedures include: - Echocardiogram to visualize heart valve function and structure - Electrocardiogram (ECG) to detect abnormal heart rhythms - Blood tests, including streptococcal antibody tests (ASO titer) and markers of inflammation - Chest X-ray to assess heart size and lung status - Clinical criteria, such as the revised Jones criteria, to confirm rheumatic fever and related cardiac involvement

Treatment Protocols: Management of rheumatic heart disease aims to control inflammation, treat any ongoing infections, prevent complications, and minimize further valve damage. Treatment options may include: - Anti-inflammatory medications such as aspirin or corticosteroids to reduce inflammation during rheumatic fever episodes - Antibiotics, especially penicillin, to eradicate streptococcal bacteria and prevent recurrence - Heart failure medications if heart function is compromised - Surgical interventions, including valve repair or replacement, in severe cases - Long-term prophylactic antibiotics to prevent recurrent rheumatic fever - Lifestyle measures such as avoiding strenuous activity during active inflammation and maintaining regular medical follow-up
