What is Cardiac Troponin I (Troponin I)?

Cardiac Troponin I is measured as part of a cardiac markers panel. Your Troponin I is normal — a reassuring result, as troponin rises when heart muscle is injured.

What does a high Cardiac Troponin I mean?

Your Troponin I is elevated. Troponin is released when heart muscle is stressed or damaged. Even mild elevations should be discussed with a doctor.

If markedly elevated: Your Troponin I is critically high. This can indicate a heart attack or significant heart-muscle injury and needs EMERGENCY medical attention.
