Following a myocardial infarction, serum levels of all listed enzymes become elevated except_____________?
Show answer Hide answer
Answer: D. Serum ornithine carbamyl transferase (SOCT)
Explanation
Serum ornithine carbamyl transferase is primarily a liver enzyme and remains unaffected. Myocardial infarction causes the release of cardiac biomarkers into the serum. Enzymes like SGOT, LDH, and CPK elevate significantly following cardiac muscle damage. Myocardial infarction involves ischemic necrosis of the heart muscle tissue. Cardiac biomarkers are intracellular enzymes released into the bloodstream after injury. Tissue-specific enzymes help clinicians diagnose the precise site of cellular damage.
Blood tests for cardiac enzymes are standard diagnostic protocols in emergency rooms. Accurate biomarker analysis helps differentiate cardiac events from hepatic pathologies. Early detection of heart attacks greatly improves patient survival and recovery outcomes. Serum glutamic oxaloacetic transaminase is a well-known cardiac and liver enzyme. Lactic dehydrogenase rises significantly following both cardiac and skeletal muscle injury. Creatine phospho kinase is a classic and highly sensitive marker for myocardial damage.
