Unexplained Extremely High Creatine Kinase-MB Levels in a Cancer Patient with No Chest Pain

Abstract

Creatine kinase-MB (CK-MB) is a widely evaluated testing enzyme in diseases related to cardiac or injury. Here we relate a clinical scenario of a patient presenting with no chest pain or symptom related to the cardiac disease whose CK-MB levels were remained inordinately elevated despite normal total CK levels. Clinically and subsequent pathological examination showed no evidence of infarction, inflammation or cardiac ischemia. Further evaluation of the patient reveals the presence of the primary prostate carcinoma with the secondary metastatic lesions in the hepatic lobe.
