So i had a nonverbal pt last night in with a chf exacerbation. EKG essentially unchanged. CKMB significantly elevated at 16 (normal = 5) CK slightly elevated at 324, index elevated at 45 ( normal = 25) however troponins were only 0.11 ( upper limit of normal being 0.5). I talked to the cards fellow and he seemed less than excited I thought an elevated CKMB and elevated index like this patient had, would be pretty specific of cardiac damage, and thus would make him a ccu player but cards was fine putting him in tele. how should we interpret the ck/ckmb and index when trroponins are within the normal range but nondiagnostic?
