Importance High-sensitivity cardiac troponin I testing is widely used to evaluate patients with
suspected acute coronary syndrome. A cardiac troponin concentration of less than 5 ng/L …

Importance Low concentrations of high-sensitivity cardiac troponin I determined on
presentation to the emergency department (ED) have been shown to have an excellent …

Background Suspected acute coronary syndrome is the commonest reason for emergency
admission to hospital and is a large burden on health-care resources. Strategies to identify …

Context Although troponin assays have become increasingly more sensitive, it is unclear
whether further reductions in the threshold of detection for plasma troponin concentrations …

Background Lowering the diagnostic threshold for troponin is controversial because it may
disproportionately increase the diagnosis of myocardial infarction in patients without acute …

Background Data regarding high-sensitivity troponin concentrations in patients presenting to
the emergency department with symptoms suggestive of myocardial infarction may be useful …

Background: Guidelines acknowledge the emerging role of high-sensitivity cardiac troponin
(hs-cTnl) for risk stratification and the early rule-out of myocardial infarction, but multiple …

Background: Limited data exist on rapid risk-stratification strategies using the US Food and
Drug Administration–cleared high-sensitivity cardiac troponin I (hs-cTnI) assays. Objectives …

Background High-sensitivity cardiac troponin assays enable the early risk stratification of
patients with suspected acute coronary syndrome to identify those at low risk of myocardial …

Background: High-sensitivity cardiac troponin assays can help to identify patients who are at
low risk of myocardial infarction in the emergency department. We aimed to determine …
