Background: Whether Copeptin combined with high sensitivity troponin below the respective decision cut-offs improves rule-out of NSTEMI and may predict all-cause death at 30-day is under debate.

Methods: Data on 10,329 patients from 5 trials were pooled to evaluate the diagnostic and prognostic performance of an initial Copeptin below decision cut-off in combination with a (hs)-cTn below the uppler limit of normal (ULN) compared to a) the initial (hs)-cTn alone in the standard serial sampling strategy based on the 99th percentile and b) a single marker strategy (SMS) based on hs-cTn < limit of detection. Endpoints were sensitivities and negative predictive values (NPV) for rule-out of NSTEMI, 30-day all-cause mortality and rates of eligibility for DMS or SMS.

Background: Combined testing of copeptin and troponin at presentation to the emergency department (ED) has been shown to possess a high negative predictive value (NPV) for ruling out acute myocardial infarction (AMI) in patients with suspected acute coronary syndrome.

Purpose: The aim of this study was to evaluate the diagnostic performance of the combination of copeptin and troponin for the exclusion of AMI in emergency patients with acute cardiac chief complaints and to assess diagnoses and outcome in copeptin-positive patients.

Methods: In this prospective study, 537 consecutive patients with cardiac chief complaints were recruited from the ED.

Objectives: Over the past few years, the number of patients attending emergency services has increased steadily. As a result, emergency departments (EDs) worldwide face frequent crowding, with the risk of reduced treatment quality and impaired patient outcome, patient and staff dissatisfaction and inefficient use of ED resources. A qualitative process analysis and process modelling was used as a method to detect critical process steps in the ED with respect to time and efficiency.

Objectives: To evaluate the relationship between chief complaints and their underlying diseases and outcome in medical emergency departments (EDs).

Methods: All 34 333 patients who attended two of the EDs of the Charité Berlin over a 1-year period were included in the analysis. Data were retrieved from the hospital information system.

Objective: Soluble fms-like tyrosine kinase 1 (sFlt1) is involved in the pathophysiology of preeclampsia and coronary artery disease. Because sFlt1 has a heparin-binding site, we investigated whether or not heparin releases sFlt1 from the extracellular matrix.

Methods And Results: We measured sFlt1 before and after heparin administration in 135 patients undergoing coronary angiography, percutanous coronary intervention, or both.
