OBJECTIVES This study was designed to test the usefulness of a bedside assay as compared to a laboratory method of troponin testing to predict adverse cardiac outcome of chest pain patients. METHODS We studied 358 ER visits of patients suspected of a non ST-elevation acute coronary syndrome. cTnI (Immulite, DPC) on a lab analyser and cTnT (Cardiac Reader,(More)
OBJECTIVES The study sought to examine the safety and performance of transcatheter aortic valve replacement (TAVR) using an all-female registry and to further explore the potential impact of female sex-specific characteristics on clinical outcomes after TAVR. BACKGROUND Although women comprise 50% of patients with symptomatic severe aortic stenosis(More)
Background In smokers treated with fibrinolysis for ST-elevation myocardial infarction (STEMI) a paradoxical beneficial short-term outcome has been reported. This was attributed to favorable clinical and angiographic baseline variables and a better response to fibrinolysis. During follow-up infarct artery reocclusion is an important prognosticator. We(More)
PURPOSE To assess current antithrombotic treatment strategies in the Netherlands in patients undergoing transcatheter aortic valve implantation (TAVI). METHODS For every Dutch hospital performing TAVI (n = 14) an interventional cardiologist experienced in performing TAVI was interviewed concerning heparin, aspirin, thienopyridine and oral anticoagulation(More)
BACKGROUND The EuroSCORE, worldwide used as a model for prediction of mortality after cardiac surgery, has recently been renewed. Since October 2011, the EuroSCORE II calculator is available at the EuroSCORE website and recommended for clinical use. The intention of this paper is to compare the use of the initial EuroSCORE and EuroSCORE II as a risk(More)
Over the last years, measurements of quality of care have become more and more a public product, used by providers, purchasers and consumers, and patients. This information serves as an important guide for improvement, as well as a decision support tool for everybody taking part in medical treatment. This evolution can be compared with advertising and as in(More)
BACKGROUND Despite improving experience and techniques, ischemic and bleeding complications after transcatheter aortic valve implantation (TAVI) remain prevalent and impair survival. Current guidelines recommend the temporary addition of clopidogrel in the initial period after TAVI to prevent thromboembolic events. However, explorative studies suggest that(More)
BACKGROUND After successful thrombolysis, a high-grade stenosis at 24-hour angiography is strongly predictive of reocclusion and is often believed to result in high reinfarction rates. However, routine angioplasty did not reduce death or reinfarction in past trials. Systematic angiographic follow-up shows that reocclusion often occurs without clinical(More)
Dipyridamole reduces reperfusion-injury in preclinical trials and may be beneficial in patients undergoing coronary angioplasty, but its effect on patients undergoing coronary artery bypass grafting (CABG) is unknown. We hypothesized that dipyridamole limits myocardial reperfusion-injury in patients undergoing CABG. The trial design was a double-blind trial(More)
