The mean age was 67years (range 19–96). There were 104 (67%) male patients. A troponin level of greater than 0.5μg/L was found in 30/156 (19%); 126 (81%) patients had normal troponin levels.

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 ...
