Summary
Rheumatic heart disease (RHD) is a preventable yet widespread cause of early death in young people globally. This review highlights recent progress in RHD epidemiology, diagnosis, and management, alongside future research needs.
Area of Science:
- Cardiology
- Public Health
- Tropical Medicine
Background:
- Rheumatic heart disease (RHD) is a significant global health issue, disproportionately affecting impoverished populations and causing substantial cardiovascular morbidity and mortality in young individuals.
- Despite being preventable for decades, RHD persists due to factors like poverty, complex disease progression, inconsistent penicillin access, and a lack of coordinated efforts in endemic areas.
Purpose of the Study:
- To provide an updated review of the latest advancements in the epidemiology, diagnosis, and management of rheumatic heart disease (RHD).
- To identify critical research questions concerning RHD pathophysiology, implementation barriers, and policy solutions for effective disease control.
Main Methods:
- This review synthesizes current scientific literature and research findings on rheumatic heart disease.
- It incorporates recent epidemiological data, diagnostic innovations, and therapeutic strategies.
Main Results:
- Recent scientific interest has spurred advancements in understanding and addressing RHD.
- Progress has been made in epidemiological surveillance, diagnostic accuracy, and management protocols for RHD.
Conclusions:
- Despite challenges, renewed scientific focus offers optimism for combating RHD.
- Translating current knowledge into effective policy and management strategies is crucial for reducing the global burden of RHD.

Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...

43
The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...

Rheumatic heart disease (RHD) management can be divided into two main strategies: prevention and long-term management.Primary PreventionPrimary prevention focuses on timely diagnosis and management of group A streptococcal pharyngitis to prevent acute rheumatic fever. The most widely used antibiotic for treating this condition is intramuscular benzathine penicillin G.Acute Rheumatic Fever TreatmentThe primary treatment goal for a patient diagnosed with acute rheumatic fever is to suppress the...

AssessmentA comprehensive assessment is essential in managing a patient with rheumatic heart disease (RHD). Begin with obtaining a detailed medical history, including recent streptococcal infections, a history of rheumatic fever, or previously diagnosed rheumatic heart disease. Assess the patient for symptoms such as fever, chest pain, widespread joint pain (arthralgia), tachycardia, pericardial friction rub, muffled heart sounds, heart murmurs, peripheral edema, subcutaneous nodules, and...

01:25Endocarditis I: Introduction
20
Introduction:Endocarditis is the infection of the endocardium, the inner lining of the heart and its valves. When the heart muscle is involved, the condition is termed myocarditis, while an infection of the outer lining is called pericarditis. Infective endocarditis (IE) primarily affects the endocardium, where pathogens adhere to the valves or lining, forming vegetation that can lead to severe complications. Infective endocarditis occurs when microorganisms, usually bacteria from other body...

01:29Heart Failure II: Pathophysiology
23
Systolic Heart Failure and Compensatory MechanismsSystolic heart failure (also termed HFrEF, Heart Failure with Reduced Ejection Fraction) is the most prevalent type of heart filure. It results in a decreased volume of blood being pumped from the ventricle. The aortic arch and carotid sinuses have baroreceptors that detect reduced blood pressure, triggering the sympathetic nervous system (SNS) to release epinephrine and norepinephrine. Initially, this response aims to boost heart rate and...
