Brielle Calderon · Answer 1

The correct answer is option c. "Troponin I".

Explanation:

The primary cardiac marker to indicate a potential myocardial injury (MI) is troponin I. Troponin I has a relevant role in cardiac and skeletal muscle, as it regulates muscular contraction by holding the actin-tropomyosin complex. When a person experiences a heart attack episode, the levels of troponin I become elevated and if they remained elevated it could indicate the presence of a potential MI.
