Differential diagnosis of infective endocarditis.

Infective endocarditis (IE) is a deadly disease if left untreated. Early detection and treatment of IE reduces the high mortality rate. Mitral valve prolapse is now the leading risk factor for development of IE. The Duke (1994) criteria includes echocardiography as a diagnostic tool. Outclient i.v. therapy is increasing due to once-daily dosing regimens, which reduces the cost of treatment. Identifying at risk clients and educating them is vital to the prevention of IE. This article familiarizes the primary care provider with the pathophysiology, clinical presentation, diagnostic testing, complications, medical treatment, prophylactic management, and client education of IE.
