Answer

The troponin level is frequently minimally elevated in acute pericarditis, usually in the absence of an elevated total creatine kinase level. Presumably, this is due to some involvement of the epicardium by the inflammatory process.

Although the elevated troponin may lead to the misdiagnosis of acute pericarditis as a myocardial infarction, most patients with an elevated troponin and acute pericarditis do not have findings at angiography consistent with acute coronary syndrome. An elevated troponin level in acute pericarditis typically returns to normal within 1-2 weeks and is not associated with a worse prognosis.
