Bacterial endocarditis

Endocarditis is an infection of the lining of the heart or the heart valves. Bacteria that enter the bloodstream cause it. Once in the blood, these bacteria can infect the inside of the heart or lodge on heart valves.

The most common ways bacteria can enter the blood are:

• from shared needles during drug use
• after an injury with an open wound
• during surgical procedures and
• during dental procedures

An infection of the heart lining is very serious. People with bacterial endocarditis need treatment with antibiotics that are given by vein. After these medicines are stopped, antibiotics will probably be given by mouth for a time. It is important that all medicines are taken so the infection is completely eliminated.

Bacteria will more likely cause a heart infection if the heart is already damaged. Dentists and doctors often prescribe antibiotics to people with heart damage before they have any kind of surgery.

The most important thing to remember about bacterial endocarditis is how to prevent it. People who are at risk of developing bacterial endocarditis are people with heart conditions such as abnormal heart valves. Abnormal heart valves may result in a leaky heart valve, mitral valve prolapse or a valve replacement. If you have any of these problems or if you have had, rheumatic fever, or endocarditis, tell your healthcare provider and dentist. Be sure to follow all instructions for your medications.
