Troponin is shown in red (subunits not distinguished). Upon binding calcium, troponin moves tropomyosin away from the myosin-binding sites on actin (bottom), effectively unblocking it. Modified ...

The rate of cardiac injury as determined by cTnI in this study was 19%. In trying to identify any factors that may contribute to an overestimation of cardiac injury, we consider the use of cTnI ...

A bracelet-like device that measures levels of troponin-I in the blood could provide a more efficient way of detecting a heart attack, according to US researchers. The wearable developed by RCE ...

Cardiac enzymes ― also known as cardiac biomarkers ― include myoglobin, troponin and creatine kinase. Historically, lactate dehydrogenase, or LDH, was also used but is non-specific.

Results were collected and recorded on 156 patients over eight months from January to September 2003. This represented 85% of 184 eligible patients. Twenty-eight (15%) patients were excluded ...
