 (trō′pə-nĭn, trŏp′ə-)
A calcium-regulated protein, composed of three subunits, that is found in skeletal and cardiac muscle and regulates contraction by interacting with tropomyosin to control the binding of myosin to actin. Blood troponin levels are a biomarker for muscle damage, as in myocardial infarction.

Importantly, however, the assay detects the identical Troponin T epitopes as previous generations.
IN PATIENTS WITH CHRONIC obstructive pulmonary disease and heightened cardiovascular risk, high levels of high-sensitivity cardiac troponin are strongly associated with risk of poor cardiovascular outcomes, according to a post-hoc analysis of a clinical trial.

Global Banking News-September 27, 2018-Abbott passes the CE MARK for first High Sensitive Troponin-I blood troponin test to predict chances of heart attack in otherwise healthy people
Abbott announced that its High Sensitive Troponin-I blood test is the first troponin test with CE Mark that can more accurately predict the chances of having a heart attack or other cardiac event potentially months to years in advance in people who otherwise appear healthy.
Medical technology company Siemens Healthineers revealed on Wednesday that the US Food and Drug Administration has cleared High-Sensitivity Troponin I assays (TnIH)1 for the Atellica IM and ADVIA Centaur XP/XPT in vitro diagnostic analysers, two new tests designed for faster diagnosis of life-threatening heart attacks.
Cardiac troponin I measurements showed significant difference (p<0.01) between the four hemodynamic profiles.
The assessment of patients with potential acute coronary syndrome (ACS) [6] incorporates clinical history, electrocardiograms (ECGs), and cardiac troponin (cTn) testing (1, 2).
Measurement of cardiac troponin (cTn) is useful in the diagnosis of acute myocardial infarction.
Madam, cardiac troponin is the diagnostic mainstay for cardiomyocyte damage.1 The newly emerging high-sensitivity cardiac troponin T (hs-cTnT) assay has improved sensitivity and precision in detecting myocardial injury and infarct than the standard troponin T assays.1 The hs-cTnT assay is being clinically used in many countries now.
Objective: To compare the levels of high sensitivity troponin I in plasma after specimen re-centrifugation in patients presenting with acute coronary syndrome.
After the lengthy trek, about 9% of the walkers had elevated levels of troponin, a protein released into the blood when the heart is damaged.
