Keywords: pericarditis, prognosis (PubMed Search)
Major and minor clinical prognostic predictors for pericarditis have been described as follows:
Major: fever > 38 degrees C, subacute onset, large effusion, tamponade, lack of response to aspirin or NSAIDs after at least 1 week of therapy
Minor: myopericarditis, immunodepression, trauma, oral anticoagulant therapy
Patients with any of these criteria [major or minor] should strongly be considered for admission. In the absence of these factors, studies show that patients managed as outpatients do well.
