Infective endocarditis: identification and management in the emergency department.

Recognition of infective endocarditis in the emergency department continues to be a challenge, as its signs and symptoms can be subtle, laboratory results are limited, and it can involve or lead to many other serious conditions. With the increase in use of medical access devices, implantable cardiac devices, and the rise of intravenous drug use, the epidemiology of infective endocarditis is changing. Diagnostic imaging has evolved, and the use of point-of-care ultrasound and transthoracic echocardiography are critical in making an early diagnosis. This review provides a best-evidence approach to diagnostic strategies, antibiotic recommendations, and surgical treatment recommendations for infective endocarditis.
