Troponin isn't normally found in the blood. When heart muscles become damaged, troponin is sent into the bloodstream. As heart damage increases, greater amounts of troponin are released in the blood. Troponins are a group of proteins found in skeletal and heart (cardiac) muscle fibers that regulate muscular contraction. Troponin tests measure the level of cardiac-specific troponin in the blood to help detect heart injury.

av J Nilsson · 2020 · Citerat av 5 — One patient (20%) in the NIHP group had a pathological cardiac troponin I (cTnI) > 0.02 ng/mL at the end of preservation compared with all 

Because an elevated troponin concentration is not specific for myocardial infarction, troponin evaluation to rule out myocardial infarction should be performed only if clinically indicated. About Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy & Safety How YouTube works Test new features Press Copyright Contact us Creators Troponin tests are used, together with an electrocardiogram (ECG), in people with persistent chest pain taken to hospital as an emergency to see if they have had a heart attack.

Up to 17% of patients may have elevated troponin levels, according to a study performed in the ED. 2. The causes of the elevation are debated, but it is important.

13 Careful clinical evaluation, measuring serial troponin values to assess the rise and fall in concentration, and the absolute concentration of troponin are used to make an assessment regarding the cause of cardiac injury.

High sensitivity assays are the biomarkers of choice. BAKGRUND. Vid muskelkontraktion sker en energiberoende glidning mellan tjocka (aktin) och tunna (myosin) fibrer i muskelcellerna. Rörelsen regleras av interaktionen mellan troponinkomplexet och kalcium. I troponinkomplexet ingår 3 proteiner: Troponin T (TnT), Troponin C (TnC) och Troponin I (TnI).
