Question
Mrs. Jones, a diabetic, is admitted to the hospital on November 25th. It appears that she has had an acute myocardial infarction (AMI), but did not feel the severe chest pain because of diabetic neuropathy. She has not felt well since November 20th and her physician believes she possibly had an AMI on November 20th.Assuming that the infarct was uncomplicated, which of the following cardiac biomarkers would most likely still be elevated and would assist in an AMI diagnosis?The correct answer is highlighted below Myoglobin Creatine kinase MB (CK-MB) Troponin T Insulin
Solution
The cardiac biomarker that would most likely still be elevated and would assist in an AMI diagnosis is Troponin T. This is because Troponin T remains elevated for a longer period of time after a heart attack compared to other biomarkers. It starts to increase within 3-4 hours after the heart attack, reaches its peak in about 24 hours, and can remain elevated for up to 14 days. This makes it a useful biomarker for diagnosing a heart attack that occurred in the past.
