CK-MB vs Troponin cardiac enzymes
What is the significance of using CK-MB and Troponin
CK-MB and Troponin are both used to rule in or out MI during chest pain. They both rise in about 3-6hours after onset of chest pain. But the clinical significance is that CK-MB falls back to normal values in a couple of days where as troponin stays elevated for longer. Hence CK-MB is used to detect reinfarctions in patients.
