    Signs and tests

    Doctors might suspect endocarditis in people with a history of:

    • Congenital heart disease
    • Intravenous drug use
    • Recent dental work
    • Rheumatic fever

    The health care provider may detect a new heart murmur, or a change in a previous heart murmur. Examination of the nails may show splinter hemorrhages.

    An eye exam may show bleeding in the retina a central area of clearing. This is known as Roth's spots. There may be small, pinpoint hemorrhages (petechiae) in the conjunctiva. The fingertips may be enlarged, and the nails may appear curved. This is called clubbing.

    Tests:

    • Blood culture
    • Complete blood count (CBC)
    • Chest x-ray
    • C-reactive protein (CRP)
    • Echocardiogram
    • ECG
    • Erythrocyte sedimentation rate (ESR)
    • Serology
    • Transesophageal echocardiogram
