For
many years the American Heart Association has
recommended that people who have certain types of
heart conditions should take antibiotics before
dental procedures. The purpose of this was to ensure
that the patient would avoid infective endocarditis,
an infection of the heart. previously known as
bacterial endocarditis. . The AHA’s latest
guidelines were published in its scientific
journal,
Circulation,
in April 2007. The new guidelines indicate that most
of the patients who needed to take antibiotics in the
past no longer are required to take them.
t
The guidelines are based on recent studies that indicate the risks of taking preventive antibiotics outweigh the benefits for most patients. The risks from these antibiotics range from mild to severe adverse reactions to in rare cases, death. Inappropriate use of antibiotics can also lead to the development of drug-resistant bacteria.
Researchers have found that there is no evidence that taking the antibiotics prior to a dental procedure will prevent infective endocarditis in patients at risk of developing a heart infection. These bacteria in the mouth are already able to enter their blood streams from brushing and flossing..The guidelines say patients who have taken prophylactic antibiotics routinely in the past but no longer need them include people with:

- mitral valve prolapse
- rheumatic heart disease
- bicuspid valve disease
- calcified aortic stenosis
- congenital heart conditions such as ventricular septal defect, atrial septal defect and hypertrophic cardiomyopathy.
Preventive antibiotics prior to a dental procedure are advised for patients with:
- artificial heart valves
- a history of infective endocarditis
- certain specific, serious congenital (present from birth) heart conditions, including
- a cardiac transplant that develops a problem in a heart valve.
