Acute Rheumatic Fever and Heart Disease Howard Sacher, D.O. Long Island Cardiology and Internal Medicine
Uncommon in the USA but overlooked • Peak incidence is between ages 5-15 • Diagnosis is based on the Jones Criteria and confirmation of Strep infection • May involve the mitral valve most commonly, but other valves can also be affected
RF is a systemic immune process 2nd to hemolytic strep infection • S/S commence 2-3 weeks post infection • But ranges from 1-5 weeks • Must evaluate new immigrants for RF • RF is rare before 4yoa and after 40yoa • Pathopneumonic lesion: • Perivascular granulomatous rxn with vasculitis • MV is attacked 75-80% • AoV is attacked 30%, but rarely is it the only valve affected • TV and PV is attacked 5% of the time
Dx with Jones Criteria • Presence of • 2 major criteria or • 1 major and 1 minor criteria
Major: Carditis Erythema Marginatum with subcutaneous nodules Sydenham’s chorea Arthritis Minor: Fever Polyarthralgias Reversible Inc PR interval Inc ESR Evidence of antecedent group B hemolytic Strep infection Hx of RF Jones Criteria
Rheumatoid Arthritis Osteomyelitis Endocarditis Chronic meningococemia “Surgical Abdomen SLE Lyme Disease Sickle Cell Anemia A host of other diseases DDX of RF
Complications • CHF • Arrhythmias • Pericarditis with effusion • Rheumatic pneumonitis
Treatment • Strict bed rest until temperature returns to normal without medications and ESR is normal (<100/min in adults) • Medications: • Salicylates • Benzathine - PCN
Prevention and Prognosis • Early treatment of Strep Pharyngitis • Immediate mortality is 1-2% with initial episode • Persistent RF with cardiomegaly, mortality is poor – 30% • Rheumatic heart disease (RHD) can ensue in Adults with a single or recurrent attacks of RF
RHD • Valve cusps become rigid and deformed • Fusion of commissures • Shortening and fusion of Chordae Tendinae • Valvular Stenosis and insufficiency ensues • First clue of organic valvular disease is a murmur • Most accurately Dx with echocardiography
