Older age
Artificial (prosthetic) heart valves
Damaged heart valves (due to rheumatic fever or infections)
Congenital heart defects
Implanted heart device (e.g., pacemaker)
History of endocarditis
History of illegal intravenous drug use
Poor dental health
Long-term catheter use

How is endocarditis diagnosed?

Symptoms of infection
Blood cultures
Echocardiogram

What are the treatment options for endocarditis?

Broad spectrum antibiotics
Surgery to repair a damaged heart valve and to improve heart function

What are the prevention tips for endocarditis?

Understand the symptoms and signs of endocarditis and seek medical advice immediately if you develop the symptoms
Practice good dental hygiene to preserve your overall health by frequently brushing and flossing your teeth and gums, and having regular dental check-ups
