TL;DR: Patients with takotsubo cardiomyopathy had a higher prevalence of neurologic or psychiatric disorders than did those with an acute coronary syndrome and physical triggers, acute neurologics or psychiatric diseases, high troponin levels, and a low ejection fraction on admission were independent predictors for in-hospital complications.
Journal ArticleDOI
Late clinical events after clopidogrel discontinuation may limit the benefit of drug-eluting stents: an observational study of drug-eluting versus bare-metal stents.
Matthias Pfisterer,Hans-Peter Brunner-La Rocca,Peter Buser,Peter Rickenbacher,Patrick Hunziker,Christian Mueller,Raban Jeger,Franziska Bader,Stefan Osswald,Christoph Kaiser,Basket-Late Investigators +10 more
TL;DR: After the discontinuation of clopidogrel, the benefit of DES in reducing target vessel revascularization is maintained but has to be balanced against an increase in late cardiac death or nonfatal MI, possibly related to late stent thrombosis.
Journal ArticleDOI
One-Hour Rule-out and Rule-in of Acute Myocardial Infarction Using High-Sensitivity Cardiac Troponin T
Tobias Reichlin,Christian Schindler,Beatrice Drexler,Raphael Twerenbold,Miriam Reiter,Christa Zellweger,Berit Moehring,Ronny Ziller,Rebeca Hoeller,Maria Rubini Gimenez,Philip Haaf,Mihael Potocki,Karin Wildi,Cathrin Balmelli,Michael Freese,Claudia Stelzig,Heike Freidank,Stefan Osswald,Christian Mueller +18 more
TL;DR: Using a simple algorithm incorporating hs-cTnT baseline values and absolute changes within the first hour allowed a safe rule-out as well as an accurate rule-in of AMI within 1 hour in 77% of unselected patients with acute chest pain.
Journal ArticleDOI
Utility of Absolute and Relative Changes in Cardiac Troponin Concentrations in the Early Diagnosis of Acute Myocardial Infarction

TL;DR: Absolute changes of cTn levels have a significantly higher diagnostic accuracy for AMI than relative changes, and seem to be the preferred criteria to distinguish AMI from other causes ofcTn elevations.
Journal ArticleDOI
Incremental cost-effectiveness of drug-eluting stents compared with a third-generation bare-metal stent in a real-world setting: randomised Basel Stent Kosten Effektivitäts Trial (BASKET).
Christoph Kaiser,Hans-Peter Brunner-La Rocca,P. Buser,Piero O. Bonetti,Stefan Osswald,André Linka,Alain Bernheim,Andreas W Zutter,Michael J. Zellweger,Leticia Grize,M Pfisterer +10 more
TL;DR: In a real-world setting, use of DES in all patients is less cost effective than in studies with selected patients, and use of these stents could be restricted to patients in high-risk groups.
