BACKGROUND It is unknown whether the preferred 1-stent bifurcation stenting approach with stenting of the main vessel (MV) and optional side branch stenting using drug-eluting stents should be finalized by a kissing balloon dilatation (FKBD). Therefore, we compared strategies of MV stenting with and without FKBD. METHODS AND RESULTS We randomized 477(More)
BACKGROUND In low-risk patients, the zotarolimus-eluting stent has been shown to reduce rates of restenosis without increasing the risk of stent thrombosis. We compared the efficacy and safety of the zotarolimus-eluting stent versus the sirolimus-eluting stent in patients with coronary artery disease who were receiving routine clinical care with no direct(More)
BACKGROUND Among drug-eluting stents released to date, the sirolimus-eluting stent has demonstrated the least amount of late lumen loss, but its efficacy and safety have not been compared head-to-head with the next-generation everolimus-eluting stent. METHODS AND RESULTS The Scandinavian Organization for Randomized Trials with Clinical Outcome IV (SORT(More)
BACKGROUND Third-generation biodegradable polymer drug-eluting stents might reduce the risk of stent thrombosis compared with first-generation permanent polymer drug-eluting stents. We aimed to further investigate the effects of a biodegradable polymer biolimus-eluting stent compared with a durable polymer-coated sirolimus-eluting stent in a(More)
BACKGROUND The sirolimus-eluting stent has demonstrated the least amount of late lumen loss among previously released drug-eluting stents, but its safety and efficacy has not been compared head-to-head with the everolimus-eluting stent. METHOD The Scandinavian Organization for Randomized Trials with Clinical Outcome (SORT OUT) IV trial was designed as a(More)
Patients with diabetes mellitus (DM) have a worse outcome after percutaneous coronary intervention (PCI) than nondiabetic patients. The purpose of this study was to compare rates of stent thrombosis, myocardial infarction (MI), target lesion revascularization (TLR), and death in diabetic and nondiabetic patients treated with primary PCI for ST-segment(More)
A Danish surveillance group established after the introduction of oral vitamin K prophylaxis monitored Danish cases with late onset vitamin K deficiency bleeding by regular questionnaires to all paediatric departments. Six cases were reported, one of whom died and three are severely handicapped. All cases occurred among an estimated 134,500 infants given a(More)
The aim of the present study was to evaluate angiographic late luminal loss after the implantation of sirolimus-eluting Cypher stents and paclitaxel-eluting Taxus stents in patients with diabetes. The study was a Danish multicenter, open-label, randomized trial. One hundred fifty-three patients with diabetes with coronary artery disease were randomized to(More)
20 male elite long distance runners were compared to a control group of blood donors to determine the effect of training on red blood cells. The acute effects of exercise on red cells were investigated in 11 of the runners following a race of 15–30 km. The runners had elevated resting values of red cell 2,3-DPG (P<0.05) and mean cell volume (P<0.01); blood(More)
