Undetectable high-sensitivity cardiac troponin T level in the emergency department and risk of myocardial infarction.
OBJECTIVES This study sought to evaluate if an undetectable (<5 ng/l) high-sensitivity cardiac troponin T (hs-cTnT) level and an electrocardiogram (ECG) without signs of ischemia can rule out myocardial infarction (MI) in the emergency department (ED). BACKGROUND Chest pain is a common symptom often associated with benign conditions, but may be a sign of MI. Because there is no rapid way to r...
متن کاملDefining high-sensitivity cardiac troponin concentrations in the community.
BACKGROUND High-sensitivity cardiac troponin (hs-cTn) assays are now available that can detect measurable troponin in significantly more individuals in the general population than conventional assays. The clinical use of these hs-cTn assays depends on the development of proper reference values. Therefore, our objective was to define hs-cTnI reference values and determinants in the general commu...
متن کاملHigh-sensitivity troponin T concentrations in acute chest pain patients evaluated with cardiac computed tomography.
BACKGROUND For evaluation of patients with chest pain and suspected acute coronary syndrome (ACS), consensus guidelines recommend use of a cardiac troponin cut point that corresponds to the 99 th percentile of a healthy population. Most conventional troponin methods lack sufficient precision at this low level. METHODS AND RESULTS In a cross-sectional study, 377 patients (mean age 53.7 years, ...

Background—For evaluation of patients with chest pain and suspected acute coronary syndrome (ACS), consensus guidelines recommend use of a cardiac troponin cut point that corresponds to the 99th percentile of a healthy population. Most conventional troponin methods lack sufficient precision at this low level. Methods and Results—In a cross-sectional study, 377 patients (mean age 53.7 years, 64....
متن کاملBiological and analytical variability of a novel high-sensitivity cardiac troponin T assay.
BACKGROUND High-sensitivity cardiac troponin assays will augment the frequency of increased results, making important the determination of reference change values to distinguish acute from chronic increases. We assessed short- and long-term biological variability of cardiac troponin T (cTnT) in healthy subjects with a novel high-sensitivity (hs) assay. METHODS We collected blood from 20 healt...
