Which cardiac biomarker is used to evaluate damage to heart muscle?

• A. LFTs
• B. UA
• C. Troponin
• D. Urine preg

Answer: (C)

Troponin is the biomarker used to evaluate damage to heart muscle. Cardiac troponin I and troponin T are proteins specific to cardiac muscle that are released into the bloodstream when myocardial cells are injured, such as during a heart attack. Because they are highly specific to the heart and rise readily with injury, measuring troponin provides a sensitive and reliable indication of myocardial damage, helps confirm Diagnosis, and aids in monitoring progression and response to treatment. Levels begin to rise within a few hours after injury and stay elevated for several days, which makes them useful even if symptoms started before testing. The other options measure unrelated tissues or conditions—liver injury (LFTs), urinary/renal issues (urinalysis), or pregnancy status (urine pregnancy test)—and do not indicate heart muscle damage.
