How can you reduce the risk of infective endocarditis?
Good oral health is generally more effective in reducing your risk of bacterial endocarditis than is taking preventive antibiotics before certain procedures. Take good care of your teeth and gums by: Seeking professional dental care every six months. Regularly brushing and flossing your teeth.
What are the recommendations for endocarditis prophylaxis?
The prophylactic antibiotic should be effective against viridans group streptococci. The guidelines recommend 2 grams of amoxicillin given orally as a single dose 30-60 minutes before the procedure as the drug of choice for infective endocarditis prophylaxis.
When is SBE prophylaxis recommended?
The American Heart Association currently recommends antibiotic prophylaxis only in patients with the following high-risk cardiac conditions: Patients with prosthetic cardiac valves. Patients with previous infective endocarditis. Cardiac transplant recipients with valve regurgitation due to a structurally abnormal valve.
What is the drug of choice for endocarditis?
👉 For more insights, check out this resource.
Treatment with aqueous penicillin or ceftriaxone is effective for most infections caused by streptococci. A combination of penicillin or ampicillin with gentamicin is appropriate for endocarditis caused by enterococci that are not highly resistant to penicillin.
What are the risk factors for infective endocarditis?

Risk factors
- Older age. Endocarditis occurs most often in older adults over age 60.
- Artificial heart valves.
- Damaged heart valves.
- Congenital heart defects.
- Implanted heart device.
- A history of endocarditis.
- A history of illegal IV drug use.
- Poor dental health.

How is infective endocarditis treated?
Treatment Regimens for Infectious Endocarditis
| Microorganism | Parenteral antibiotic regimen |
|---|---|
| Oxacillin-resistant staphylococci | Vancomycin for six weeks |
| Enterococcus strains susceptible to penicillin, gentamicin, and vancomycin | Ampicillin plus gentamicin for four to six weeks |
| or | |
| Penicillin plus gentamicin for four to six weeks |
When do you give infective endocarditis prophylaxis?
The rationale for prophylaxis against IE is: endocarditis usually follows bacteraemia, certain interventional procedures cause bacteraemia with organisms that can cause endocarditis, these bacteria are usually sensitive to antibiotics; therefore, antibiotics should be given to patients with predisposing heart disease …
Can cephalexin be used for dental prophylaxis?
Before you have any dental procedure we recommend that you take 2 grams of cephalexin (Keflex) one hour prior to the procedure. If you are allergic to cephalexin or penicillin or are unable to take cephalexin (Keflex) for any other reason we recommend that you take clindamycin 600 mg one hour before the procedure.
Does cephalexin treat endocarditis?
Keflex (cephalexin) is a cephalosporin antibiotic prescribed to treat bacterial infections. Keflex is also used before dental procedures in patients identified with certain heart-related conditions to prevent bacterial infections of the heart known as endocarditis.
Why is gentamicin used in endocarditis?
Synergy is needed with an aminoglycoside in order to achieve a bactericidal effect because most cell-wall active drugs are only considered bacteriostatic against enterococci. Of the two aminoglycosides used to treat enterococcal endocarditis, gentamicin is primarily used unless resistance is present.
What three critical elements are required for the pathogenesis of infective endocarditis?
The pathophysiology of infective endocarditis comprises at least three critical elements: preparation of the cardiac valve for bacterial adherence, adhesion of circulating bacteria to the prepared valvular surface, and survival of the adherent bacteria on the surface, with propagation of the infected vegetation.
Do you need to premed for artificial heart valve?
Patients who have had surgery for placement of prosthetic heart valves or prosthetic intravascular or intracardiac materials are at risk for the development of an infection and should be given premedication according to the 2007 AHA guidelines.
Is there a “treatment” for endocarditis?
Methods and Results— This work represents the third iteration of an infective endocarditis “treatment” document developed by the American Heart Association under the auspices of the Committee on Rheumatic Fever, Endocarditis, and Kawasaki Disease, Council on Cardiovascular Disease of the Young.
Does endocarditis complicate electrophysiological devices?
The Committee has also published a statement 18 on endocarditis that complicates electrophysiological (pacemakers, intracardiac defibrillators), ventricular assist, and other nonvalvular cardiac devices.
What is the epidemiology of infective endocarditis?
Infective endocarditis is a potentially lethal disease that has undergone major changes in both host and pathogen. The epidemiology of infective endocarditis has become more complex with today’s myriad healthcare-associated factors that predispose to infection.
What is the American College of Cardiology Evidence-Based Practice Guide?
It includes an evidence-based system for diagnostic and treatment recommendations used by the American College of Cardiology and the American Heart Association for treatment recommendations.
