Question

question 46 (mandatory) (1 point) a 69 - year old male patient presents with sudden onset of shortness of breath and chest pain. the pain began yesterday after working hard in his garden. what isoenzyme would most likely come back as positive? a) cpk - bb b) cpk - 1 c) cpk - mb d) cpk - mm

Explanation:

The patient has sudden - onset shortness of breath and chest pain, which may be related to a cardiac event. Creatine phosphokinase (CPK) has isoenzymes. CPK - MB is predominantly found in cardiac muscle and is often elevated in myocardial infarction or other cardiac - related issues. CPK - BB is mainly in brain and smooth muscle, CPK - 1 is not a standard CPK isoenzyme notation in this context, and CPK - MM is mainly in skeletal muscle. Given the cardiac - related symptoms, CPK - MB is most likely to be positive.

Answer:

c) CPK - MB
