A client has a history of Rheumatic Fever. The nurse understands this client is at a higher risk for developing which condition?

Rheumatic fever is an inflammatory complication of group A streptococcal pharyngitis, and its most significant long-term consequence is rheumatic heart disease, which most commonly affects the mitral valve. The inflammatory process triggered by molecular mimicry damages valve leaflets and the subvalvular apparatus, leading most often to mitral stenosis or mitral regurgitation over time. This occurs because streptococcal antigens share structural similarities with cardiac tissue, causing the immune system to attack the heart valves. Mitral valve disease — particularly stenosis — is therefore the classic chronic complication that nurses must recognize. Chronic kidney disease is not a direct sequela of rheumatic fever; the kidneys are not a primary target organ in this disease process. Hemophilia is a hereditary coagulation disorder with no association with rheumatic fever. Abdominal aortic aneurysm relates to degenerative atherosclerotic changes and is unrelated to a prior streptococcal or rheumatic inflammatory process. Recognizing this connection is important for client education: clients with a history of rheumatic fever should receive ongoing cardiac monitoring and, in some cases, antibiotic prophylaxis before dental or surgical procedures to prevent further valve damage from bacteremia.
