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 ...

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 ...

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 ...
