Abstract

A 24 year old male with varicella myocarditis was admitted with chest pain and fever up to 39°C. The ECG showed J point and ST elevation in leads V2–V4, and inverted T waves in leads V5 and V6. Creatine kinase (CK) was raised to 435 U/l (CK-MB 36 U/l), troponin I was 63.4 μg/l, and lactate dehydrogenase was 359 U/l, suggesting cardiac involvement of varicella infection. The left ventricle was dilated (58 mm) and left ventricular ejection fraction was globally reduced (ejection fraction 45%). Myocarditis was confirmed by endomyocardial biopsy. The patient was treated with specific varicella hyperimmunoglobulins, aciclovir, and a non-steroidal anti-inflammatory drug. During two months follow up the patient recovered completely. This case report is a reminder that a varicella infection can cause myocarditis in adults. Early diagnosis and appropriate treatment of this rare form of myocarditis may lead to complete recovery.
