What is Cardiac Biomarker of Choice for diagnosis of Re-infarction 8 days after the initial ischemic event is: and explain in detail?
Answer is B (CK-MB) CK-MB is the Cardiac Biomarker of Choice for diagnosis of Re-infarction 8 days after the initial ischemic event. The CK-MB level will increase approximately 4-8 hours after a myocardial infarction and return to normal after 72 hours (3 days). This makes it useful for the detection of re-infarction in the 4-10 day time window after the initial insult since troponins may remain elevated for 10-14 days making it less useful for this purpose.
