22 lis 2011 · Assays for cTn, namely cTnI and cardiac troponin T (cTnT), are the preferred diagnostic tests for ACS, in particular non–ST-segment–elevation myocardial infarction, because of the tissue-specific expression of cTnI and cTnT in the myocardium.
1 kwi 2022 · A raised troponin concentration may be a sign of myocardial injury rather than infarction. Figure 2 shows the relative time courses of the major cardiac causes of chest pain including acute myocardial infarction.
Myocardial injury (infarction) requires at least one troponin value above the 99 th percentile. In acute myocardial injury (including infarction) the troponin level should rise or fall during repeated sampling. To rule in or rule out acute myocardial infarction ≥2 analyses of troponin are obtained.
9 wrz 2021 · In patients with troponin above this concentration, the UDMI recommends a differentiation of myocardial infarction from injury, and emphasizes the use of the best imaging techniques available to define aetiology of myocardial injury (preferably cardiac magnetic resonance imaging). 1 See text for further details.
14 wrz 2017 · 1. Introduction. Intensive investigation into the mechanisms of striated muscle contraction during the late 50 s and early 60 s led to evidence of a protein that resembled tropomyosin and regulated the calcium sensitivity of the actomyosin contractile apparatus.
cardiac troponin T (cTnT), are the preferred diagnostic tests for ACS, in particular non–ST-segment–elevation myocardial infarction, because of the tissue-specific expression of cTnI and cTnT in the myocardium. The results of cTn testing often guide the decision for coronary intervention. However, al-though the increasing sensitivity of cTn
2 paź 2023 · Cardiac troponin I and T are specific and sensitive biomarkers of myocardial injury. They are the preferred serologic tests for the evaluation of patients with suspected acute myocardial infarction. (See "Use of creatine kinase to detect myocardial injury", section on 'Why troponin is preferred'.)
