ENDOCARDITIS
What is Endocarditis?
Endocarditis is an infection in the inner lining of your heart. This lining is called the endocardium. The infection usually happens when bacteria or germs get into your blood and travel to your heart.
Causes
Endocarditis is often caused by bacteria that enter your body through:
Dental work or gum disease
Surgery or medical procedures
Infected skin or wounds
IV drug use (using needles to inject drugs)
Some people have a higher risk of getting endocarditis, like those with:
Heart valve problems or artificial valves
Congenital (birth) heart defects
Past heart infections
Symptoms
You may have one or more of these symptoms:
Fever or chills
Tiredness or weakness
Night sweats
Muscle or joint pain
Chest pain or shortness of breath
Cough
Loss of appetite or weight
Swelling in feet, legs, or belly
Tiny red or purple spots on the skin, inside the mouth, or under the nails
Always tell your nurse or doctor if you feel sick or something feels “off.”
Treatment
Endocarditis is a serious illness that usually needs:
IV antibiotics (medicine given through a vein for several weeks)
Hospital stay to monitor your heart and body
Sometimes surgery to fix or remove damaged heart valves
You must finish all your antibiotics, even if you start to feel better.
Diet and Precautions
Eat healthy foods to help your body fight infection.
Avoid high-salt foods if you have swelling or heart problems.
Keep your mouth clean—brush and floss daily.
Take antibiotics before certain dental or medical procedures if your doctor tells you to.
Don’t use IV drugs.
Let your care team know about any cuts, sores, or infections.
When to Call the Home Health Nurse or Doctor
Call your home health nurse or doctor if you:
Have a fever, chills, or feel more tired than usual
Notice swelling, pain, or redness at your IV site
Feel dizzy, weak, or short of breath
Miss a dose of medicine or have trouble taking it
Have any signs of a new infection (cough, sore throat, rash)
When to Go to the Emergency Room
Go to the emergency room right away if you:
Have chest pain or trouble breathing
Faint or feel like you’re going to pass out
Have slurred speech or weakness in your face, arms, or legs
Can’t wake up or respond normally
Have very fast or very slow heartbeat
