Question

The diagnostic test for myocardial infarction is

• A. Creatinine kinase test
• B. Haematocrit
• C. Total blood count
• D. Urine test

Hint:

CK-MB is the cardiac-specific enzyme measured in suspected myocardial infarction.

Answer 1

The Correct Option is A

Creatinine kinase (CK), specifically the CK-MB isoenzyme, is released into the blood when there is damage to cardiac muscle, making it a key diagnostic marker for myocardial infarction (heart attack). Other options are not specific indicators for cardiac injury.
