Chronic rheumatic heart disease (RHD) is a long-term cardiovascular condition resulting from rheumatic fever, which is a complication of untreated streptococcal throat infections. The condition is characterized by damage to heart valves due to inflammatory processes that occur during rheumatic fever, leading to valve stenosis or regurgitation. RHD primarily affects children and young adults in regions with limited access to healthcare and affordable antibiotics, though it can arise at any age following rheumatic fever.

The risk factors for developing chronic rheumatic heart disease include repeated episodes of rheumatic fever, which can occur due to inadequate treatment of streptococcal throat infections. Socioeconomic factors such as poverty, overcrowded living conditions, and limited access to healthcare play a significant role in increasing susceptibility. Additionally, a family history of rheumatic fever or rheumatic heart disease may elevate an individual's risk of developing chronic RHD.

Symptoms of chronic rheumatic heart disease may vary depending on the severity of the valve damage but often include shortness of breath, fatigue, palpitations, and swelling of the legs or abdomen due to fluid retention. Patients may also experience chest pain or discomfort, particularly during physical activity. Some individuals may remain asymptomatic for years before symptoms develop or progress.

Chronic rheumatic heart disease is primarily caused by rheumatic fever, which results from an untreated streptococcal throat infection. The body’s immune response to this infection can lead to inflammation in various tissues, including the heart. Repeated episodes of rheumatic fever can cause damage to the heart valves over time, leading to chronic complications such as stenosis or regurgitation.

The diagnosis of chronic rheumatic heart disease typically involves a thorough clinical history, assessment of symptoms, and physical examination, with an emphasis on heart murmurs that may indicate valve dysfunction. Diagnostic imaging, particularly echocardiography, plays a crucial role in visualizing structural changes in the heart valves. Additional tests, including electrocardiograms (ECGs) and chest X-rays, may be utilized to assess heart function and identify any associated complications.

Management of chronic rheumatic heart disease focuses on alleviating symptoms, preventing complications, and addressing underlying valve damage. This may include medications such as diuretics to manage fluid retention, anticoagulants to prevent blood clots, or antibiotics to prevent further streptococcal infections. In severe cases, surgical intervention, such as valve repair or replacement, may be necessary to restore proper heart function.

Preventive measures for chronic rheumatic heart disease focus on the prompt and effective treatment of streptococcal throat infections with appropriate antibiotics, such as penicillin. Public health initiatives aimed at improving living conditions, healthcare access, and education regarding the importance of seeking medical care for throat infections are critical in reducing the incidence of rheumatic fever. Additionally, individuals with a history of rheumatic fever are often advised to follow a long-term prophylaxis regimen to prevent recurrence.
