What lab markers are typically elevated in the case of acute myocardial infarction?

In the context of acute myocardial infarction (AMI), the most relevant lab markers are troponin and CK-MB. Troponin is a protein found in heart muscle and is released into the bloodstream when heart muscle cells are damaged, which occurs during an MI. The elevation of troponin levels is highly specific for myocardial injury and is often used as a key diagnostic tool in the assessment of acute coronary syndromes.

CK-MB, or creatine kinase-MB, is an enzyme found predominantly in heart muscle, and its levels also rise in the event of myocardial injury. While troponin is the preferred marker due to its specificity and sensitivity, CK-MB can provide additional information, especially in the setting of recurrent chest pain or to determine reinfarction.

The other options include markers that are not relevant or lack specificity in the diagnosis of acute myocardial infarction. Albumin and bilirubin are commonly associated with liver function and other non-cardiac conditions, while glucose and cholesterol levels do not directly indicate myocardial injury. B-type natriuretic peptide (BNP) is useful in diagnosing heart failure but is not specific to acute myocardial infarction. Therefore, the choice of troponin and CK-MB is accurate for diagnosing
