BACKGROUND Data on the comparative value of the circumferential pulmonary vein and the segmental pulmonary vein ablation for interventional treatment of atrial fibrillation are limited. We hypothesized that the circumferential pulmonary vein ablation approach was superior to the segmental pulmonary vein ablation approach. METHODS AND RESULTS One hundred(More)
Although new, possibly curative radiofrequency ablation techniques for atrial fibrillation (AF) have been developed in recent years, little is known about the mechanisms of spontaneous onset of AF episodes. Using a 12-lead 24-hour Holter monitoring system, we aimed to characterize such episodes. A total of 297 spontaneous episodes of AF in 33 patients with(More)
BACKGROUND Diabetes mellitus is associated with an increased risk of restenosis, stent thrombosis, and death after percutaneous coronary interventions. Little is known about the late outcome of patients with diabetes mellitus who receive drug-eluting stents (DES). METHODS This study includes a prospective database of 2557 consecutive patients with(More)
OBJECTIVES The aim of this study was to investigate the evolution of left ventricular (LV) function and infarct size in patients with acute myocardial infarction (MI) treated with primary coronary stenting. BACKGROUND Little evidence exists on the relationship between LV function and evolution of infarct size after MI. METHODS This study included 626(More)
BACKGROUND Bioresorbable coronary stents might improve outcomes of patients treated with percutaneous coronary interventions. The everolimus-eluting bioresorbable vascular scaffold is the most studied of these stent platforms; however, its performance versus everolimus-eluting metallic stents remains poorly defined. We aimed to assess the efficacy and(More)
AIMS The aim of this study is to investigate whether the benefit of abciximab in patients with non-ST-segment elevation acute coronary syndromes (NSTE-ACSs) undergoing percutaneous coronary intervention (PCI) after pre-treatment with 600 mg clopidogrel is sustained at 1 year. METHODS AND RESULTS We performed 1-year follow-up of 2022 high-risk patients(More)
BACKGROUND Despite a large amount of data assessing outcomes of out-of-hospital cardiac arrests (OHCAs), little information is available about physician-staffed emergency medical service (EMS) systems. The aim of our study was to investigate the impact of a physician on the outcome of patients after OHCA. METHODS This is a prospective, observational study(More)
BACKGROUND In disease of the femoropopliteal artery, paclitaxel-coated balloon (PCB) therapy improved angiographic outcomes as compared with uncoated balloon (UCB) angioplasty. Nevertheless, it remains uncertain whether PCB may reduce the need for reintervention. METHODS AND RESULTS We searched Medline, EMBASE, the Cochrane Central Register of Controlled(More)
AIMS The purpose of the study was to compare the efficacy and safety of sotalol and bisoprolol in the maintenance of sinus rhythm after electrical cardioversion of atrial fibrillation. METHODS Patients (n=128) were randomized to sotalol (80 mg b.i.d.) or bisoprolol (5 mg x day(-1)). Patients with contraindications to beta-blockers, class III(More)
OBJECTIVES The objective of this study was to investigate the impact of no-reflow phenomenon on 5-year mortality among patients with acute ST-segment elevation myocardial infarction (STEMI) treated by primary percutaneous coronary intervention (PCI). This impact was also assessed in relation to infarct size. BACKGROUND The impact of no-reflow on long-term(More)
