WebApr 24, 2024 · There is great interest in widening the use of high-sensitivity cardiac troponins for population cardiovascular disease (CVD) and heart failure screening. However, it is not clear whether cardiac troponin T (cTnT) and troponin I (cTnI) are equivalent measures of risk in this setting. WebElevated troponin is a sensitive and specific indication of myocardial damage, with troponin release from myocytes into the systemic circulation. In and of itself, elevated troponin does not indicate myocardial infarction (myonecrosis due to ischemia); rather, it is nonspecific relative to the etiology of myocardial damage.

WebIntroduction: High sensitivity troponin (hs-cTn) and diagnostic algorithms are used to rapidly triage patients with symptoms of acute myocardial infarction in emergency departments (ED). However, few studies have evaluated the impact of simultaneously implementing hs-cTn and a rapid rule-out algorithm on length of stay (LOS). WebHigh-sensitivity cardiac troponin (hs-cTn) High-sensitivity cardiac troponin is a newer type of testing that can detect lower levels of troponin. This may help diagnose heart injury and acute coronary syndrome earlier. Your healthcare provider will explain which type of troponin testing was done and what the results mean for you.

WebApr 5, 2024 · INTRODUCTION. Cardiac troponin (cTn) is the standard blood-based test to confirm the diagnosis of acute myocardial infarction. (See "Diagnosis of acute myocardial infarction", section on 'Definitions' .) However, troponin is not specific for acute thrombotic occlusion of a coronary artery, the most common precursor to acute myocardial infarction. WebThe sensitivity for acute MI was 100% with a MI3 value ≤3.13 and 353 (67%) ruled-out after 30 minutes. At 30−45 days, there were 2 (0.6%) MACEs (2 non-cardiac deaths) in the low-risk group, in the intermediate-risk group 4 (3.0%) MACEs (3 acute MIs, 1 cardiac death), and in the high-risk group 4 (9.1%) MACEs (4 acute MIs, 2 cardiac deaths).
