= delayed pericarditis (one week to one month) after an acute myocardial infarction or cardiac trauma
- chest pain – usually pleuritic in nature
- low-grade fever
- shortness of breath
- pericardial friction rub
- in severe cases associated with a large pericardial effusion – muffled heart sounds, signs of pericardial tamponade – tachycardia, hypotension, elevated JVP; electrical alternans on ECG
Treatment is usually with aspirin; in more severe cases, steroids or colchicine can be used. If a significant pericardial effusion is present, they need pericardiocentesis.
