“…These include myocarditis [ 19 ], pulmonary embolism [ 20 , 21 ], cardiac trauma [ 22 ], heart transplantation [ 23 ], chemotherapy-induced cardiotoxicity [ 24 ], and cardiac surgery [ 25 ]. However, CK-MB levels in these diseases/conditions do not add significant value to their diagnosis or the prognosis, and often cause confusion in the interpretation of the results [ 19 , 21 , 22 , 23 , 24 , 25 , 26 , 27 ]. Moreover, increased CK-MB levels do not specify the underlying etiology, and false-positive results can occur in a number of non-cardiovascular conditions, including end-stage renal failure [ 28 ], skeletal muscle trauma [ 22 ], muscular dystrophy [ 29 ], dermatomyositis [ 30 ], rhabdomyolysis [ 31 ], delirium tremens [ 32 ], and amyloidosis [ 33 ].…”
