What Are Cardiac Markers?
Cardiac markers are specific proteins and enzymes released into the bloodstream when heart muscle cells are damaged or stressed. Troponin I and Troponin T are highly sensitive and specific markers for heart muscle damage, while CK-MB (Creatine Kinase-MB) is an enzyme that rises when cardiac tissue is injured.
These markers are crucial for diagnosing heart attacks (myocardial infarction), monitoring cardiac health, and assessing treatment effectiveness. Our AI-powered report interpreter online analyzes these values in context, providing comprehensive risk assessment and clinical insights.
Why Troponin Is the Gold Standard
Troponin is the most sensitive and specific marker for detecting heart muscle damage. Even minimal cardiac injury releases troponin into the bloodstream, making it invaluable for early detection of heart attacks and cardiac events.
- High sensitivity: Detects even minor heart muscle damage
- Cardiac specificity: Rarely elevated by non-cardiac conditions
- Early detection: Rises within 3-4 hours of cardiac injury
- Prolonged elevation: Remains elevated for 7-14 days
- Risk stratification: Higher levels indicate more severe damage
CK-MB: The Classic Cardiac Enzyme
CK-MB is a cardiac-specific isoenzyme of creatine kinase that provides valuable information about heart muscle damage. While troponin has largely replaced CK-MB for diagnosis, it remains useful for monitoring and timing of cardiac events.
Clinical Uses
Timing cardiac events, monitoring reperfusion therapy, detecting reinfarction
Time Course
Rises 3-8 hours, peaks 12-24 hours, normalizes 48-72 hours
