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 کاملUndetectable Concentrations of a Food and Drug Administration–approved High‐sensitivity Cardiac Troponin T Assay to Rule Out Acute Myocardial Infarction at Emergency Department Arrival
BACKGROUND The objective of this study was to quantify the sensitivity of very low concentrations of high-sensitivity cardiac troponin T (hsTnT) at ED arrival for acute myocardial infarction (AMI) in a large cohort of chest pain patients evaluated in real-world clinical practice. METHODS This retrospective study included consecutive ED patients with suspected cardiac chest pain evaluated in f...
متن کاملWill high-sensitivity troponin improve the evaluation of patients with chest pain in the emergency department?
s p g c Approximately 8 million people in the United States are evaluated for chest pain in the emergency department (ED) each year at an estimated cost of over $10 billion (1,2). Most of these individuals do not have an acute coronary syndrome (ACS). However, atypical symptoms of myocardial ischemia are common in certain patient subsets, and the initial electrocardiogram (ECG) is often normal ...
متن کاملHigh-sensitivity versus conventional troponin in the emergency department for the diagnosis of acute myocardial infarction
INTRODUCTION Recently, newer assays for cardiac troponin (cTn) have been developed which are able to detect changes in concentration of the biomarker at or below the 99th percentile for a normal population. The objective of this study was to compare the diagnostic performance of a new high-sensitivity troponin T (HsTnT) assay to that of conventional cTnI for the diagnosis of acute myocardial in...
متن کاملClinical, organizational and economic analysis of high-sensitivity cardiac troponin testing in the emergency department
The measurement of cardiac troponins (cTns) has become the mainstay for the diagnosis of acute coronary syndrome (ACS), since the assessment of either cardiac troponin T (cTnT) or cardiac troponin I (cTnI) has now outperformed whatever other available biomarker, to be used alone or in combination with cTns (1). This paradigm shift has been strongly supported by recent introduction in clinical p...
