What laboratory test is used to assess cardiac enzyme levels?

• A. Creatinine levels
• B. Troponin levels
• C. B-type natriuretic peptide (BNP)
• D. Liver function tests

Answer: (B)

Troponin levels are crucial in assessing cardiac enzyme levels because troponins are proteins found in cardiac muscle. When there is damage to the heart, such as during a myocardial infarction (heart attack), troponin is released into the bloodstream. Therefore, measuring troponin levels in the blood provides an objective way to determine whether heart muscle injury has occurred. Elevated levels of troponin can indicate not only acute coronary syndrome but also other heart-related issues. Other laboratory tests mentioned serve different purposes: creatinine levels are primarily used to assess kidney function; B-type natriuretic peptide (BNP) is utilized to evaluate heart failure; and liver function tests assess the health of the liver. Thus, troponin levels are specifically indicated for evaluating cardiac event related to muscle injury, making them the choice relevant to assessing cardiac enzyme levels.
