Culture-negative endocarditis

Endocarditis (culture-negative)

The American Heart Association recommends preventive antibiotics for people at risk for infectious endocarditis before:

• Certain dental procedures
• Surgeries on respiratory tract or infected skin, skin structures, or musculoskeletal tissue

Antibiotics are more likely to be recommended those with the following risk factors:

• Artificial heart valves
• Certain congenital heart defects, both before or possibly after repair
• History of infective endocarditis
• Valve problems after a heart transplant

Continued medical follow-up is recommended for people with a previous history of infectious endocarditis.

Persons who use intravenous drugs should seek treatment for addiction. If this is not possible, use a new needle for each injection, avoid sharing any injection-related paraphernalia, and use alcohol pads before injecting to reduce risk.
