Infective endocarditis (IE) is a common cause of embolic strokes. Early diagnosis and treatment are essential to decrease the risk of ischemic stroke and ensure appropriate treatment, particularly given the higher risk of hemorrhagic complications. Treatment is also essential to prevent other complications such as heart failure, perivalvular abscesses, or intracranial abscesses. Transthoracic echocardiogram (TTE) and transesophageal echocardiogram (TEE) may not show endocardial involvement in the early stages of IE and, rarely, some patients may lack systemic signs of infection, making the early detection of IE challenging. Multifocal ischemic strokes may be the initial manifestation of IE and warrant further workup directed at IE even if initial echocardiogram findings are negative. A high index of clinical suspicion and thorough history are of utmost importance.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
