Question

In clinical enzymology, why is Cardiac Troponin I (cTnI) preferred over Creatine Kinase-MB (CK-MB) in parallel diagnostic protocols for acute myocardial infarction?
Options
A Higher cardiac tissue specificity and longer diagnostic window
Correct Answer
B Lower cost and faster enzymatic reaction kinetics
C Complete absence in skeletal muscle under all pathophysiological conditions
D Ability to cross the blood-brain barrier rapidly
Correct Answer

Option A is the correct answer.

Detailed Explanation

Troponin I exhibits high absolute myocardial specificity and stays elevated longer than CK-MB, reducing false positive diagnoses from skeletal muscle injury.
