Infective endocarditis: Difference between revisions

Revision as of 01:19, 20 February 2025

Infective endocarditis is a serious infection of the inner lining of the heart chambers and valves (endocardium). It is usually caused by bacteria entering the bloodstream and settling in the heart.

Causes

Infective endocarditis is typically caused by bacteria, but can also be caused by fungi or other microorganisms. The most common bacteria that cause infective endocarditis are Staphylococcus aureus, Streptococcus viridans, and Enterococcus species. These bacteria can enter the bloodstream through activities such as brushing teeth, eating, or through medical procedures.

Symptoms

Symptoms of infective endocarditis can vary, but may include fever, chills, fatigue, aching joints and muscles, night sweats, shortness of breath, paleness, persistent cough, swelling in feet, legs or abdomen, and unexplained weight loss.

Diagnosis

Diagnosis of infective endocarditis is usually made through a combination of physical examination, blood tests, and imaging tests such as an echocardiogram or a cardiac CT scan.

Treatment

Treatment for infective endocarditis usually involves high-dose antibiotics, often given intravenously. In severe cases, surgery may be needed to repair or replace damaged heart valves.

Prevention

Prevention of infective endocarditis involves good oral hygiene and avoiding activities that can cause bacteria to enter the bloodstream. In some cases, people at high risk of infective endocarditis may be given antibiotics before certain medical or dental procedures.
