Study Notes
Rheumatic Heart Disease
Rheumatic heart disease (RHD) is a chronic, largely preventable, and neglected cardiovascular disease, particularly affecting low-income and middle-inch countries (LMICs). Despite advancements in high-income countries (HICs), the burden of RHD persists in LMICs due to the lack of investment in research and prevention strategies.
Causes of Rheumatic Heart Disease
RHD is caused by episodes of acute rheumatic fever (ARF), which occurs following a Group A streptococcus (GAS) infection. Infectious agents like GAS trigger an autoimmune response, resulting in inflammation of heart tissue and, potentially, valvular damage.
Symptoms of Rheumatic Heart Disease
RHD typically presents during childhood and adolescence, although symptoms may appear later in life. Common features include arthralgia (joint pain), carditis (heart inflammation usually involving the mitral valve), myocardial involvement (sinus tachycardia), and pericarditis (chest pain).
Acute Rheumatic Fever
Acute rheumatic fever symptoms occur weeks after a GAS infection. Carditis is the main feature, affecting multiple layers of the heart, particularly the mitral valve. Arthralgia, involving large joints, is common, followed by pericarditis, characterized by chest pain and mild effusion.
Treatment of Rheumatic Heart Disease
Primary prevention strategies aim to reduce GAS infections and early diagnosis through screening and improved living conditions. Penicillin remains the cornerstone of antibiotic prophylaxis. For advanced cases of RHD, valve repair or replacement may be necessary, depending on the severity of valvular dysfunction.
Diagnosis of Rheumatic Heart Disease
Diagnostic criteria have evolved since Jones' original description, now including subclinical carditis detected by echocardiography. Tools like the Jones Criteria, with updated parameters, aid in early detection and treatment.
Prevention of Rheumatic Heart Disease
Prevention measures focus on enhancing social circumstances, effective delivery of antibiotic prophylaxis, and recognizing the value of simple echocardiographic tools in resource-limited settings. An improvement in social determinants of health and a better understanding of immunogenic determinants may help in vaccine development.
Explore the causes, symptoms, diagnosis, treatment, and prevention of Rheumatic Heart Disease through this informative quiz. Learn about the impact of acute rheumatic fever episodes, common symptoms like arthralgia and carditis, and primary prevention strategies for this neglected cardiovascular disease.
