ComplicationsCardiac tamponade, myocarditis, constrictive pericarditis[1][2]
Usual onsetTypically sudden[1]
DurationFew days to weeks[3]
CausesViral infection, tuberculosis, uremic pericarditis, following a heart attack, cancer, autoimmune disorders, chest trauma[4][5]
Diagnostic methodBased on symptoms, electrocardiogram, fluid around the heart[6]
Differential diagnosisHeart attack[1]
TreatmentNSAIDs, colchicine, corticosteroids[6]
PrognosisUsually good[6][7]
Frequency3 per 10,000 per year[2]

Pericarditis is inflammation of the pericardium, the fibrous sac surrounding the heart.[8] Symptoms typically include sudden onset of sharp chest pain, which may also be felt in the shoulders, neck, or back.[1] The pain is typically less severe when sitting up and more severe when lying down or breathing deeply.[1] Other symptoms of pericarditis can include fever, weakness, palpitations, and shortness of breath.[1] The onset of symptoms can occasionally be gradual rather than sudden.[8]

The cause of pericarditis often remains unknown but is believed to be most often due to a viral infection.[4][8] Other causes include bacterial infections such as tuberculosis, uremic pericarditis, heart attack, cancer, autoimmune disorders, and chest trauma.[4][5] Diagnosis is based on the presence of chest pain, a pericardial rub, specific electrocardiogram (ECG) changes, and fluid around the heart.[6] A heart attack may produce similar symptoms to pericarditis.[1]

Treatment in most cases is with NSAIDs and possibly the anti-inflammatory medication colchicine.[6] Steroids may be used if these are not appropriate.[6] Symptoms usually improve in a few days to weeks but can occasionally last months.[3] Complications can include cardiac tamponade, myocarditis, and constrictive pericarditis.[1][2] Pericarditis is an uncommon cause of chest pain.[9] About 3 per 10,000 people are affected per year.[2] Those most commonly affected are males between the ages of 20 and 50.[10] Up to 30% of those affected have more than one episode.[10]
