Acute pericarditis usually presents with chest pain and diffuse ST segment elevation on ECG. Several reports indicate that large numbers of patients with a diagnosis of acute pericarditis have elevated troponin I, a sensitive and highly specific marker for cardiac injury, and this suggests a high incidence of concomitant, otherwise, silent myocarditis. This case patient had elevated troponin I which is a biomarker of myocardial injury and injury pattern of ST segment elevation on ECG accompanied in military tuberculosis.
