Heart Inflammation Symptoms


If you have chest pain or severe shortness of breath, or your symptoms get worse, call 9-1-1 or seek medical help right away.

The symptoms of heart inflammation can happen suddenly or progress slowly. You may have severe symptoms or almost no symptoms.

Some of the symptoms may feel like the flu, and most often, myocarditis and pericarditis go away on their own after a few weeks. However, for some symptoms, such as chest pain or shortness of breath, it can be hard to tell whether they will go away on their own, or if they are caused by a heart attack or other serious health problem.

If a virus causes your heart inflammation, you may have a cough, runny nose, or gastrointestinal (stomach or intestinal) symptoms a few weeks before you notice any symptoms of heart inflammation.
