Endocarditis
What is Endocarditis?
Endocarditis is an infection of the inner lining of your heart chambers and valves. This lining is called the endocardium. Bacteria or fungi enter your bloodstream and attach to damaged areas of your heart. The infection can damage or destroy your heart valves over time.
This condition is serious and needs quick treatment. Without care, endocarditis can lead to heart failure or stroke. It most often affects people who already have heart valve damage or artificial valves. People with certain heart defects are also at higher risk.
Early detection through blood testing makes treatment more effective. Rite Aid offers testing that can help identify signs of infection in your blood. Catching endocarditis early helps protect your heart from permanent damage.
Symptoms
- Fever and chills that come and go
- A new heart murmur or change in an existing murmur
- Fatigue and weakness that persists
- Night sweats that soak your sheets
- Shortness of breath during activity or rest
- Small painful red or purple spots on fingers or toes
- Unexplained weight loss over weeks
- Swelling in your feet, legs, or abdomen
- Aching joints and muscles
- Blood in your urine
Some people have mild symptoms at first that seem like the flu. Others develop severe symptoms quickly. Symptoms can vary based on which germs are causing the infection and whether you have existing heart problems.

Causes and risk factors
Endocarditis happens when bacteria or fungi enter your bloodstream and settle on your heart lining. This can occur during dental procedures, surgery, or even from everyday activities like brushing your teeth. The germs attach to damaged heart tissue or artificial valves. Your body tries to fight the infection by forming clumps of bacteria, immune cells, and clotting proteins called vegetations.
Risk factors include damaged or artificial heart valves, congenital heart defects, and a history of endocarditis. Intravenous drug use greatly increases risk due to repeated blood infections. Poor dental health allows bacteria from your mouth to enter your bloodstream. People with weakened immune systems or chronic illnesses are also more vulnerable to developing this infection.
How it's diagnosed
Doctors diagnose endocarditis through blood tests and imaging. Blood cultures are the most important test. They identify specific bacteria or fungi causing the infection. Your doctor will order multiple blood samples taken at different times. A high white blood cell count shows your body is fighting an infection.
Rite Aid offers blood testing that includes WBC count and can help detect signs of infection. An echocardiogram uses sound waves to create images of your heart valves. This test can show vegetations or valve damage. Your doctor may also order additional tests to check for complications. Early testing leads to faster treatment and better outcomes.
Treatment options
- High doses of intravenous antibiotics given in the hospital for 4 to 6 weeks
- Antifungal medications if the infection is caused by fungi
- Surgery to repair or replace damaged heart valves in severe cases
- Regular blood tests to monitor treatment response
- Good dental hygiene to prevent future infections
- Antibiotics before dental or medical procedures if you have risk factors
- Avoid intravenous drug use completely
- Treat any skin infections promptly to prevent spread
- Follow up with a cardiologist regularly after treatment

Frequently asked questions
Endocarditis is caused by bacteria or fungi that enter your bloodstream and attach to your heart lining. This often happens through dental procedures, medical procedures, or skin infections. People with damaged heart valves or artificial valves are at highest risk because germs stick more easily to abnormal tissue.
Symptoms can develop over days or weeks depending on the type of bacteria involved. Acute endocarditis from aggressive bacteria causes severe symptoms within days. Subacute endocarditis develops slowly over weeks or months with milder symptoms. Either type needs immediate medical attention once symptoms appear.
Yes, blood tests are essential for diagnosing endocarditis. Blood cultures identify the specific bacteria or fungi causing the infection. A high white blood cell count shows your immune system is responding to infection. Doctors typically order multiple blood samples taken at different times for accurate results.
Untreated endocarditis is extremely dangerous and often fatal. The infection can destroy heart valves, cause heart failure, or lead to stroke. However, with prompt antibiotic treatment, most people recover fully. Early detection through blood testing and quick medical care greatly improve survival rates.
People with artificial heart valves or damaged valves face the highest risk. Those with congenital heart defects or a history of endocarditis are also vulnerable. Intravenous drug users have significantly increased risk due to repeated blood infections. Anyone with a weakened immune system should take extra precautions to prevent infections.
You can reduce your risk through good dental hygiene and prompt treatment of infections. People at high risk may need antibiotics before dental or surgical procedures. Avoid intravenous drug use completely. Keep your skin clean and treat cuts or scrapes right away to prevent bacteria from entering your bloodstream.
Most people need intravenous antibiotics for 4 to 6 weeks. Treatment usually starts in the hospital and may continue at home with a PICC line. Your doctor will monitor your blood tests regularly to ensure the infection is clearing. Some patients need valve surgery in addition to antibiotics for complete recovery.
Yes, endocarditis can recur, especially in people with artificial valves or ongoing risk factors. Following all treatment instructions reduces your risk of recurrence. Take preventive antibiotics before dental work if your doctor recommends them. Regular follow-up with your cardiologist helps catch any problems early.
Damaged valves may need surgical repair or replacement. Your surgeon can repair some valves by removing infected tissue and reconstructing the valve. In severe cases, the damaged valve is removed and replaced with an artificial or biological valve. Most people do well after valve surgery when combined with proper antibiotic treatment.
Yes, seek medical attention immediately if you have fever and known heart valve issues. Early blood testing can detect the infection before serious damage occurs. Your doctor will likely order blood cultures and check your white blood cell count. Prompt diagnosis and treatment prevent complications and improve your chances of full recovery.
