Current Cardiac Biomarkers

The current cardiac biomarkers that we will mention are listed below. Some of these markers have arguably become obsolete and some are considered much more esoteric than others.
  • Troponin I (cTnI)
  • Troponin T (cTnT)
  • CK-MB
  • Myoglobin (rarely used)
  • CK Isoforms (never used for routine work-ups, mainly of academic interest)
  • BNP and NT-proBNP
