Short- and long-term risk stratification using a next-generation, high-sensitivity research cardiac troponin I (hs-cTnI) assay in an emergency department chest pain population.
BACKGROUND The next-generation, high-sensitivity cardiac troponin assays can measure quantifiable concentrations of cTn in a majority of individuals, but there are few studies assessing these assays for risk stratification. The present study was undertaken to determine if a research hs-cTnI assay can be useful for predicting death/myocardial infarction (MI), both short- and long-term, in an eme...
متن کاملBiomarkers for predicting serious cardiac outcomes at 72 hours in patients presenting early after chest pain onset with symptoms of acute coronary syndromes.
BACKGROUND Most outcome studies of patients presenting early to the emergency department with potential acute coronary syndromes have focused on either the index diagnosis of myocardial infarction (MI) or a composite end point at a later time frame (30 days or 1 year). We investigated the performance of 9 biomarkers for an early serious outcome. METHODS Patients (n=186) who presented to the e...
متن کاملVariation of cardiac troponin I and T measured with sensitive assays in emergency department patients with noncardiac chest pain.
BACKGROUND New-generation high-sensitivity assays for cardiac troponin have lower detection limits and less imprecision than earlier assays. Reference 99th-percentile cutoff values for these new assays are also lower, leading to higher frequencies of positive test results. When cardiac troponin concentrations are minimally increased, serial testing allows discrimination of myocardial infarction...
متن کاملComparison of hs-cTnI, hs-cTnT, hFABP and GPBB for identifying early adverse cardiac events in patients presenting within six hours of chest pain-onset.
A recent publication comparing and assessing high-sensitivity cardiac troponin T (hs-cTnT) with heart-type fatty-acid binding protein (hFABP) at presentation in a pooled population of patients included in the FAST II (Fast Assessment of Thoracic Pain) and FASTER I (Fast Assessment of Thoracic Pain by nEuRal networks) studies indicated no incremental value for the diagnosis of myocardial infarct...
متن کاملHigh-sensitivity cardiac troponin I for predicting death in a female emergency department population.
The Third Universal Definition of Myocardial Infarction has indicated that “sex-dependent values may be recommended for highsensitivity troponin assays” (1 ). This statement is supported by several reference-interval studies that reported that women had lower concentrations and 99th percentile cutoffs with the high-sensitivity assays than men (2, 3 ). Despite these findings, it is unclear wheth...
