Rheumatic heart disease in the developing world: prevalence, prevention, and control

Area of Science:

• Cardiology
• Public Health
• Infectious Diseases

Background:

• Rheumatic heart disease (RHD) is a prevalent cause of morbidity and mortality in developing countries.
• RHD occurrence has shown little decline over recent decades, with high incidence and prevalence rates reported.
• The disease affects both children and adults, necessitating urgent public health interventions.

Purpose of the Study:

• To highlight the ongoing burden of Rheumatic Heart Disease (RHD) in developing nations.
• To emphasize the critical need for aggressive prevention and control measures.
• To underscore the importance of secondary prophylaxis in managing RHD.

Main Methods:

• Review of existing literature and reports on Rheumatic Fever (RF) and RHD incidence and prevalence.
• Analysis of current prevention and control strategies for RHD.
• Assessment of the feasibility and impact of interventions in resource-limited settings.

Main Results:

• High rates of RF and RHD persist in developing regions.
• Key interventions include reducing streptococcal exposure, primary prophylaxis for RF, and secondary prophylaxis for RHD.
• Secondary prophylaxis is identified as the most critical intervention for preventing severe cardiac complications.

Conclusions:

• Aggressive prevention and control measures are essential to combat RHD.
• Secondary prophylaxis is the cornerstone of RHD management, especially in impoverished countries.
• Integration of RHD interventions into primary healthcare systems, with adequate resources, is vital.
