What is the difference between myocarditis and myopericarditis?
Acute myocarditis can result from a focal or diffuse infection of the myocardium. Myopericarditis occurs when the inflammation extends to the pericardium and it can be very difficult to distinguish from pure myocarditis or pericarditis using routine emergency department tests.

What is the difference between pericarditis and myocarditis?
Numerous conditions may cause inflammation in the pericardium, the pericardial cavity and/or the myocardium. Pericarditis refers to inflammation of the pericardium, and myocarditis refers to inflammation of the myocardial (muscle) tissue.
How long does it take for symptoms of pericarditis to develop?
It can sometimes take several weeks for symptoms of pericarditis to develop after bypass surgery. Many times, the cause of pericarditis is unknown. This is called idiopathic pericarditis. About 15-30% of patients with pericarditis have repeat episodes of pericarditis that come and go for many years.
What causes sharp pain in the chest from pericarditis?
Pericarditis often causes chest pain and sometimes other symptoms. The sharp chest pain associated with pericarditis occurs when the irritated layers of the pericardium rub against each other. Pericarditis usually begins suddenly but doesn’t last long (acute).
