and increasing myocyte permeability leading to the release of cardiac troponins. [34] Vasopressor agents are often used in patients with sepsis and can also be cardiotoxic, although they were only ...

This latter question is difficult to clarify as the arrhythmia provoking the shock can also cause troponin release. Inappropriate shocks secondary to lead fracture are an ideal situation to ...

Previous studies have shown the release of troponin—a group of proteins expressed only by heart muscle cells—during chemotherapy to be a biomarker that is indicative of a higher likelihood of ...

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 ...
