Name the cardiac enzymes with their importance.

Cardiac enzymes are proteins that are found in the heart muscle.

Common cardiac enzymes with normal values:

1.     Troponin:   Troponin I: less than 0.03 ng/mL.

                   Troponin T: below 0.01 ng/mL.

2.     Creatine Kinase (CK): 30 to 170 units per liter (U/L).

3.     CK-MB (Creatine Kinase-MB): less than 5% of total CK.

4.     Myoglobin: Below 90 ng/mL.

5.     Lactate Dehydrogenase (LDH): 140 to 280 U/L.

6.     Aspartate Aminotransferase (AST): 10 to 40 U/L.

 

Importance of cardiac enzyme

Cardiac enzymes are essential markers for diagnosing heart conditions, particularly myocardial infarction. Troponins, such as Troponin I and Troponin T, are highly specific to cardiac muscle, allowing for early and accurate detection of heart muscle damage. These enzymes help guide clinical decision-making, assess treatment effectiveness, and stratify the risk of future cardiac events.

Cardiac enzymes are crucial markers for detecting heart muscle damage, especially during a heart attack. Troponins, CK, CK-MB, myoglobin, LDH, and AST provide specific and sensitive information, enabling early diagnosis, risk assessment, and treatment monitoring in cardiac conditions.
