High sensitivity troponin and hemolysis
WebSection snippets Cardiac Troponin Basics. The cTn complex consists of 3 separate proteins encoded by different genes. These include cardiac troponin T (cTnT), cardiac troponin I (cTnI), and cardiac troponin C. 7 Each protein plays an important role in regulating the interaction of actin and myosin filaments and thus on cardiac contraction. Troponin C is … WebKeywords: acs risk stratification, stress test, biomarkers, high-sensitivity troponin t, myocardial ischemia Introduction Cardiac troponin (cTn) is a blood biomarker that is associated with several pathologic states [1]. One notable exception with unclear implications is that troponin can be elevated in presumably healthy people following
