Rheumatic Fever Occurs following pharyngitis caused by certain strains of group A streptococcus after a latency period of 3 weeks. Children and those exposed to them are at higher risk Outbreaks may occur in crowded conditions
Rheumatic Fever clinical features 2 major or 1 major + 2 minor and evidence of prior Strep infection: Major criteria: carditis polyarthritis chorea erythema marginatum subcutaneous nodules Minor criteria: arthralgia fever prolonged PR interval elevated ESR or CRP Prior Strep infection: (+) throat culture, (+) rapid antigen test, elevated ASO JAMA 1992; 268: 2069
Rheumatic Heart Disease clinical features A well known cause of valvular heart disease Mitral stenosis present in ~65% Aortic regurgitation Mitral regurgitation Aortic stenosis isolated AV disease ~2 5% Tricuspid and pulmonic involvement less common Not thought to cause constrictive pericarditis Not thought to cause cardiomyopathy
Rheumatic Heart Disease A Three pronged approach 1. Primary prevention: treat Strep pharyngitis 2. Secondary prevention: prophylactic abx after RF 3. Treatment of valvular disease: medical, surgical, percutaneous

Cardiology Education in Zimbabwe Objective: develop a small group of junior faculty with basic region specific qualifications in cardiology
Cardiology Education in Zimbabwe More intensive mentoring of selected postgraduates Clinical skills Research skills
Cardiology Education in Zimbabwe Clinical skills Echocardiography ECG and arrhythmia detection Pacemaker implantation Outpatient management
Cardiology Education in Zimbabwe Research skills Patient registries o Inpatient stroke o Pediatric RHD o Peripartum cardiomyopathy o Inpatient CHF 30 d mortality Atrial fibrillation Ventricular arrhythmias
Cardiology Education in Zimbabwe Cardiovascular physiology lectures for 2d year medical students Clinical cardiology lectures for 5 th year medical students
Cardiovascular Disease in Africa and Beyond Be respectful The agenda should be driven by the community being served. Listen twice before acting once
Cardiovascular Disease in Africa and Beyond Plant trees Seek sustainable growth. Create things that will outlast you. Persevere.
