“It’s not just the top of the distribution that has elevated high-sensitivity troponin, but the whole distribution is shifted to the right. Everyone has a slightly elevated value for high-sensitivity troponin. That’s what this graph suggests.”
A troponin increase occurs when your heart is damaged:
“Troponin is a type of protein found in the muscles of your heart. Troponin is not normally found in the blood. When the heart muscles are damaged, troponin is released into the bloodstream. As the heart becomes more damaged, larger amounts of troponin are released into the blood.”
