I30-I52: Other forms of heart disease

I39: Endocarditis and heart valve disorders in diseases classified elsewhere

Endocarditis and heart valve disorders in diseases classified elsewhere are health conditions that impact the heart's inner lining and physical structures like the valves. Endocarditis is typically an infection, often bacterial, of this lining, known as the endocardium. Heart valve disorders, on the other hand, disrupt the normal function of the heart valves, which control blood flow within the heart. Both conditions might result from underlying diseases such as lupus, rheumatic fever, or other systemic illnesses that indirectly affect the heart. Symptoms commonly include fatigue, shortness of breath, rapid or irregular heartbeat, and a persistent cough. Without early detection and management, these conditions may progress into more severe cardiac problems, potentially affecting the heart's ability to pump blood effectively to meet the body's needs.
