What patient education is important for prevention of infective endocarditis in at-risk individuals?

• A. Antibiotic prophylaxis before dental or invasive procedures according to guidelines, maintain good dental hygiene.
• B. Never brush teeth
• C. Avoid exercise
• D. Only take antibiotics after dental procedures

Answer: (A)

Preventing infective endocarditis in people who are at risk hinges on reducing the chance that bacteria enter the bloodstream from the mouth or during procedures and then reach the heart valves. The best approach is targeted antibiotic prophylaxis before dental or invasive procedures when guidelines indicate it, paired with consistently good dental hygiene to minimize bacteria in the mouth. Using antibiotics before procedures helps lessen the likelihood of bacteremia seeding damaged heart tissue, while maintaining dental health lowers the daily risk of bacteria entering the bloodstream. It’s important to follow current guidelines for who needs prophylaxis, which antibiotics to use, and the timing, so we protect patients without overusing antibiotics. Poor dental hygiene or delaying treatment increases risk, and other options like avoiding brushing, avoiding exercise, or taking antibiotics only after procedures do not prevent endocarditis and are not appropriate education.
