Myocarditis is an inflammation of the muscle of your heart (myocardium). The myocardium pumps blood through the heart and to other parts of the body. With myocarditis, the heart muscle can become damaged. This weakens the heart and makes it work harder. Over time, this may cause your heart to enlarge, lead to heart failure, and become life-threatening.

DISCHARGE INSTRUCTIONS:

Call your local emergency number (911 in the US) if:

• You have any of the following signs of a heart attack:
  • Squeezing, pressure, or pain in your chest
  • You may also have any of the following:
    • Discomfort or pain in your back, neck, jaw, stomach, or arm
    • Shortness of breath
    • Nausea or vomiting
    • Lightheadedness or a sudden cold sweat

Call your doctor if:

• Your signs and symptoms come back or get worse.
• You have a fever.
• You have chills, a cough, or feel weak and achy.
• You have questions or concerns about your condition or care.

Medicines:

You may need any of the following:

• Aspirin helps thin the blood to keep clots from forming. If you are told to take aspirin, do not take acetaminophen or ibuprofen instead. This medicine makes it more likely for you to bleed or bruise.
• Blood thinners help prevent blood clots. Clots can cause strokes, heart attacks, and death. Many types of blood thinners are available. Your healthcare provider will give you specific instructions for the type you are given. The following are general safety guidelines to follow while you are taking a blood thinner:
  • Watch for bleeding and bruising. Watch for bleeding from your gums or nose. Watch for blood in your urine and bowel movements. Use a soft washcloth on your skin, and a soft toothbrush to brush your teeth. This can keep your skin and gums from bleeding. If you shave, use an electric shaver. Do not play contact sports.
  • Tell your dentist and other healthcare providers that you take a blood thinner. Wear a bracelet or necklace that says you take this medicine.
  • Do not start or stop any other medicines or supplements unless your healthcare provider tells you to. Many medicines and supplements cannot be used with blood thinners.
  • Take your blood thinner exactly as prescribed by your healthcare provider. Do not skip does or take less than prescribed. Tell your provider right away if you forget to take your blood thinner, or if you take too much.
• Take your medicine as directed. Contact your healthcare provider if you think your medicine is not helping or if you have side effects. Tell your provider if you are allergic to any medicine. Keep a list of the medicines, vitamins, and herbs you take. Include the amounts, and when and why you take them. Bring the list or the pill bottles to follow-up visits. Carry your medicine list with you in case of an emergency.

Limit physical activity:

Your healthcare provider may suggest that you rest until your symptoms decrease. He or she may suggest that you avoid heavy lifting or certain physical activities. Ask what activities are safe for you, when to begin exercise, and the best exercise plan for you.

Help protect your heart:

• Eat heart healthy foods. Eat foods that help protect the heart, including plenty of fruits and vegetables, nuts, and sources of fiber. Eat foods that contain healthy fats, such as walnuts, salmon, and canola and soybean oils. You may need to eat foods low in cholesterol or sodium (salt). You also may be told to limit saturated and trans fats.
• Limit alcohol. Women should limit alcohol to 1 drink a day. Men should limit alcohol to 2 drinks a day. A drink of alcohol is 12 ounces of beer, 5 ounces of wine, or 1½ ounces of liquor.
• Do not smoke. Nicotine and other chemicals in cigarettes can cause damage to your heart. Ask your healthcare provider for information if you currently smoke and need help to quit. E-cigarettes or smokeless tobacco still contain nicotine. Talk to your healthcare provider before you use these products.

Prevent the spread of germs: (**Did you want to add this section?**)

• Wash your hands often. Wash your hands several times each day. Wash after you use the bathroom, change a child's diaper, and before you prepare or eat food. Use soap and water every time. Rub your soapy hands together, lacing your fingers. Wash the front and back of your hands, and in between your fingers. Use the fingers of one hand to scrub under the fingernails of the other hand. Wash for at least 20 seconds. Rinse with warm, running water for several seconds. Then dry your hands with a clean towel or paper towel. Use hand sanitizer that contains alcohol if soap and water are not available. Do not touch your eyes, nose, or mouth without washing your hands first.
• Cover a sneeze or cough. Use a tissue that covers your mouth and nose. Throw the tissue away in a trash can right away. Use the bend of your arm if a tissue is not available. Wash your hands well with soap and water or use a hand sanitizer.
• Stay away from others while you are sick. Avoid crowds as much as possible.
• Ask about vaccines you may need. Talk to your healthcare provider about your vaccine history. He or she will tell you which vaccines you need, and when to get them.
  • Get the influenza (flu) vaccine as soon as recommended each year. The flu vaccine is available starting in September or October. Flu viruses change, so it is important to get a flu vaccine every year.
  • Get the pneumonia vaccine if recommended. This vaccine is usually recommended every 5 years. Your provider will tell you when to get this vaccine, if needed.
