Background: Infective endocarditis may affect patients after transcatheter aortic valve replacement (TAVR).

Objectives: The purpose of this study was to provide detailed information on incidence rates, types of microorganisms, and outcomes of infective endocarditis after TAVR.

Methods: Between February 2011 and July 2018, consecutive patients from the SwissTAVI Registry were eligible.

Importance: Whether sex-specific chest pain characteristics (CPCs) would allow physicians in the emergency department to differentiate women with acute myocardial infarction (AMI) from women with other causes of acute chest pain more accurately remains unknown. OBJECTIVE To improve the management of suspected AMI in women by exploring sex-specific CPCs.

Design, Setting, And Participants: From April 21, 2006, through August 12, 2012, we enrolled 2475 consecutive patients (796 women and 1679 men) presenting with acute chest pain to 9 emergency departments in a prospective multicenter study.

Background: Current guidelines require a change (rise and/or fall) in levels of cardiac troponin (cTn) for the diagnosis of acute myocardial infarction (AMI). It is unknown whether absolute or relative changes provide higher accuracy when using high-sensitivity cTnI assays.

Methods: In a prospective international multicentre study, we assessed the diagnostic accuracy of early absolute and relative changes in cTnI measured with two novel pre-commercial high-sensitivity assays (Siemens and Beckman Coulter) in 943 unselected patients presenting to the ED with suspected AMI.

Background: We examined whether undetectable levels of high-sensitivity cardiac Troponin (hs-cTn) can be used to rule out acute myocardial infarction (AMI) with a single blood draw at presentation to the emergency department (ED).

Methods And Results: In a prospective multicenter study we used 4 different hs-cTn assays (hs-cTnT Roche, and hs-cTnI Siemens, hs-cTnI Beckman Coulter and hs-cTnI Abbott) in consecutive patients presenting with acute chest pain. The final diagnosis of AMI was adjudicated by two independent cardiologists using all available data including serial hs-cTnT levels.

Background: Absolute changes in high-sensitivity cardiac troponin T (hs-cTnT) seem to have higher diagnostic accuracy in the early diagnosis of acute myocardial infarction compared with relative changes. It is unknown whether the same applies to high-sensitivity cardiac troponin I (hs-cTnI) assays and whether the combination of absolute and relative change might further increase accuracy.

Methods: In a prospective, international multicenter study, high-sensitivity cardiac troponin (hs-cTn) was measured with 3 novel assays (hs-cTnT, Roche Diagnostics Corp, Indianapolis, Ind; hs-cTnI, Beckman Coulter Inc, Brea, Calif; hs-cTnI, Siemens, Munich, Germany) in a blinded fashion at presentation and after 1 and 2 hours in a blinded fashion in 830 unselected patients with suspected acute myocardial infarction.

Background: The introduction of high-sensitivity cardiac troponin (hs-cTn) assays allows the assessment of clinical decision values below the 99th percentile.

Methods: Final diagnosis and one-year mortality were adjudicated in a multicenter, prospective cohort of 1181 patients presenting with acute chest pain to the emergency department. Hs-cTnT (Roche) and cTnI-ultra (Siemens) were measured in a blinded fashion.

Aims: Several high-sensitivity cardiac troponin (hs-cTn) assays have recently been developed. It is unknown which hs-cTn provides the most accurate prognostic information and to what extent early changes in hs-cTn predict mortality.

Methods And Results: In a prospective, international multicentre study, cTn was simultaneously measured with three novel [high-sensitivity cardiac Troponin T (hs-cTnT), Roche Diagnostics; hs-cTnI, Beckman-Coulter; hs-cTnI, Siemens] and a conventional assay (cTnT, Roche Diagnostics) in a blinded fashion in 1117 unselected patients with acute chest pain.

Objective: To analyse whether levels of high-sensitivity cardiac troponin (hs-cTn) below their respective 99th percentile can be used as a single parameter to rule out acute myocardial infarction (AMI) at presentation.

Design: Prospective, multicentre study.

Main Outcome Measures: We measured hs-cTn using four different methods (hs-cTnT Roche, hs-cTnI Siemens, hs-cTnI Beckman Coulter and hs-cTnI Abbott) in consecutive patients presenting to the emergency department with acute chest pain.

Background: It is unknown whether unstable angina (UA) results in previously nondetectable low-level myocardial necrosis. We compared the pattern of myocardial necrosis between patients with UA, acute myocardial infarction (AMI), and noncardiac chest pain (NCCP) using 3 high-sensitive cardiac troponin (hs-cTn) assays.

Methods: In a multicenter study, we enrolled 842 unselected patients with acute chest pain in the emergency department.

Background: High-sensitivity cardiac troponin (hs-cTn) assays seem to improve the early diagnosis of acute myocardial infarction (AMI), but it is unknown how to best use them in clinical practice. Our objective was to develop and validate an algorithm for rapid rule-out and rule-in of AMI.

Methods: A prospective multicenter study enrolling 872 unselected patients with acute chest pain presenting to the emergency department.

Objectives: Due to different release mechanisms, mid-regional pro-atrial natriuretic peptide (MR proANP) may be superior to N-terminal pro-B-type natriuretic peptide (NT proBNP) in the diagnosis of acute heart failure (AHF) in patients with atrial fibrillation (AF). We compared MR proANP and NT proBNP for their diagnostic value in patients with AF and sinus rhythm (SR).

Design: Prospective cohort study.
