High sensitivity cardiac troponin testing.
Bösner and colleagues have presented evidence for a simple rule for ruling out coronary artery disease in the primary care setting. It is noteworthy that no laboratory measurements have been included in their model, with reference to their introductory statement that “ ... electrocardiography and cardiac troponin test are of limited value in primary care... ” This point deserves some discussion...
متن کاملHigh-sensitive cardiac troponin T
Cardiac troponin is the preferred biomarker for the diagnosis of acute myocardial infarction (AMI). The recent development of a high-sensitive cardiac troponin T (hs-cTnT) assay permits detection of very low levels of cTnT. Using the hs-cTnT assay improves the overall diagnostic accuracy in patients with suspected AMI, while a negative result also has a high negative predictive value. The gain ...
متن کاملMutation of the high affinity calcium binding sites in cardiac troponin C.
Fast skeletal and cardiac troponin C (TnC) contain two high affinity Ca2+/Mg2+ binding sites within the C-terminal domain that are thought to be important for association of TnC with the troponin complex of the thin filament. To test directly the function of these high affinity sites in cardiac TnC they were systematically altered by mutagenesis to generate proteins with a single inactive site ...
متن کاملHigh-sensitive cardiac troponin: friend or foe?
Cardiac troponin I and T (cTn) are structural proteins unique to the heart. Detection of cTn in peripheral blood indicates cardiomyocyte necrosis. As acute myocardial infarction (AMI) is the most important cause of cardiomyocyte necrosis, cTns have become an integral part in the diagnosis of AMI. In this indication, cTns are superior to all other biomarkers indicating cardiomyocyte necrosis suc...
متن کاملThe influence of trout cardiac troponin I and PKA phosphorylation on the Ca2+ affinity of the cardiac troponin complex.
The trout heart is 10-fold more sensitive to Ca(2+) than the mammalian heart. This difference is due, in part, to cardiac troponin C (cTnC) from trout having a greater Ca(2+) affinity than human cTnC. To determine what other proteins are involved, we cloned cardiac troponin I (cTnI) from the trout heart and determined how it alters the Ca(2+) affinity of a cTn complex containing all mammalian c...
