Understanding Endocarditis: Symptoms, Risks, Diagnosis, and Treatment

Endocarditis is a serious infection of the inner lining of your heart and heart valves, known as the endocardium. This infection occurs when bacteria from other parts of your body, such as your mouth, spread through your bloodstream and attach to the endocardium. If left untreated, endocarditis can cause permanent damage to your heart and even be life-threatening.

Symptoms of Endocarditis

The symptoms of endocarditis can vary from person to person and may develop suddenly or over time. Some common symptoms include:

• Flu-like symptoms, such as fever, chills, and night sweats

• New or changing heart murmur

• Skin changes, such as tiny bumps or spots on hands, feet, eyes, or mouth

• Loss of apetite and weight loss

• Pain on the left side of the body under the rib cage

• Blood in the urine

• Swelling in the abdomen, legs, or feet

• Shortness of breath

• Persistent cough

• Confusion or stroke-like episodes

Risk Factors for Endocarditis

While endocarditis is unlikely to develop in people with healthy hearts, certain factors can increase your risk, including:

• Damaged or artificial heart valves

• Congenital heart defects

• Previous endocarditis

• Intravenous drug use

• Recent dental, GI, or urologic procedures

Diagnosing Endocarditis

If your doctor suspects endocarditis, they may order several tests to confirm the diagnosis, such as:

• Blood tests to detect bacteria or anemia

• Echocardiogram or electrocardiogram to assess heart function

• X-ray to evaluate the impact on your heart and lungs

• CT scan or MRI to check for the spread of infection to other parts of your body

Treating Endocarditis

Treatment for endocarditis typically involves antibiotics administered through an IV, usually for several weeks. In some cases, surgery may be necessary to clear the infection or replace a damaged heart valve. Your healthcare team will work with you to determine the best course of treatment based on your specific case.

Preventing Endocarditis

Maintaining good dental hygiene is crucial in preventing endocarditis, as bacteria from oral infections can travel to your heart through your bloodstream. Be sure to brush and floss regularly and visit your dentist for check-ups. If you're at higher risk for endocarditis, be cautious when getting piercings or tattoos, as these procedures can introduce bacteria into your system. Always inform your healthcare providers about your risk for endocarditis before undergoing any medical or dental procedures, as they may prescribe antibiotics as a precautionary measure.

If you notice any symptoms of endocarditis, contact your doctor immediately. Early diagnosis and treatment can help prevent serious complications and improve your chances of a full recovery.
