Are You at Risk for Infective Endocarditis?
Published: Jan 14, 2024
Infective endocarditis is a serious heart infection that can be life-threatening. Let's explore who is most at risk and why.
Contents
High-Risk Groups
Certain individuals are at higher risk for infective endocarditis, including those with prosthetic heart valves, a history of IE, or specific congenital heart defects. These conditions make it easier for bacteria to settle on heart tissue, leading to infection. Recognizing these risk factors is crucial for prevention and timely treatment.
Intermediate Risk Factors
Patients with valve diseases, hypertrophic cardiomyopathy, or cardiovascular devices are considered at intermediate risk for IE. While not as vulnerable as high-risk groups, they still need to be aware of symptoms and preventive measures. Regular check-ups and good oral hygiene are key to mitigating risk.

The Role of Dental Procedures
Invasive dental procedures can increase the risk of IE, but not all dental work poses a threat. Procedures like tooth extractions and oral surgery are more likely to cause problems than routine cleanings. Knowing which procedures carry risk can help in making informed decisions about antibiotic prophylaxis.
