BACKGROUND The objective of this study was to evaluate the added predictive ability of the CHA(2)DS(2)VASc prediction rule for stroke and death in a nonanticoagulated population of patients with atrial fibrillation. METHODS AND RESULTS We included 1603 nonanticoagulated patients with incident atrial fibrillation from a Danish prospective cohort study of(More)
OBJECTIVE To do an indirect comparison analysis of apixaban against dabigatran etexilate (2 doses) and rivaroxaban (1 dose), as well as of rivaroxaban against dabigatranetexilate (2 doses), for their relative efficacy and safety against each other, with particular focus on the secondary prevention population for stroke prevention in atrial fibrillation. A(More)
OBJECTIVE  To study the effectiveness and safety of the non-vitamin K antagonist oral anticoagulants (novel oral anticoagulants, NOACs) dabigatran, rivaroxaban, and apixaban compared with warfarin in anticoagulant naïve patients with atrial fibrillation. DESIGN  Observational nationwide cohort study. SETTING  Three Danish nationwide databases, August(More)
BACKGROUND Oral anticoagulation therapy is monitored by the use of the International Normalized Ratio (INR). Patients who perform self-testing or self-management use a point-of-care testing (POCT) coagulometer (INR monitor) to estimate their INRs. A precondition for a correct dosage of coumarins is a correct INR estimation, and the method and apparatus used(More)
BACKGROUND Dabigatran may provide less protection against myocardial infarction than vitamin K antagonists (VKAs) in patients with atrial fibrillation. This may be particularly evident among "switchers" to dabigatran from VKA, as a result of discontinuation effects. METHODS AND RESULTS We identified in nationwide Danish registries a cohort of VKA-naïve(More)
OBJECTIVE To investigate the relative effect of warfarin versus non-vitamin K oral anticoagulants (NOACs) in thrombotic and bleeding outcomes in subgroups of atrial fibrillation (AF) patients with varying degrees of renal dysfunction. METHODS Systemic review and meta-regression analyses on NOACs versus warfarin, supplemented with indirect comparisons were(More)
BACKGROUND Fibrin formation is required for tumor angiogenesis, metastasis and invasion. Cancer discovered at the same time as or shortly after venous thromboembolism (VTE) tends to be advanced, and the prognosis poor. Previous studies have demonstrated that plasma D-dimer - a degradation product of cross-linked fibrin - correlates with tumor stage and(More)
OBJECTIVE To validate the discharge diagnoses of venous thromboembolism during pregnancy and postpartum, we examined the positive predictive value (PPV) of venous thromboembolic (VTE) discharge diagnoses associated with pregnancy or puerperium based on 311 cases registered in a Danish population-based hospital-discharge registry.

Inherited arrhythmia disorders associated with structurally normal heart (i.e. long and short QT syndrome, Brugada syndrome, catecholaminergic polymorphic ventricular tachycardia, early repolarization syndrome, idiopathic ventricular fibrillation) cause 10% of 1.1 million sudden deaths in Europe and the USA. The purpose of this European Heart Rhythm(More)
