The aim of this study is to examine temporal trends in the use oral anticoagulants (OAC) as stroke prophylaxis in patients with atrial fibrillation (AF) and to examine factors associated with OAC initiation. From Danish nationwide registries, we identified patients diagnosed with AF at Danish hospitals and outpatient clinics between January 2005 and June 2015. OAC initiation was assessed from prescription fills ±180 days from date of AF diagnosis. We identified a total of 108 410 patients with newly diagnosed AF. Before 2010, 40-50% initiated OAC treatment. From 2010, OAC initiation rates increased (P < 0.0001 for trend) and by June 2015, 66.5% of the incident AF patients were initiated on OAC (74.5% increase since December 2009). Increased OAC prescription was especially seen among females and 'fragile' patients (age > 75 years and high risk of stroke). The increased OAC initiation was accompanied by introduction and increased uptake of the NOACs. By the end of the study, NOACs accounted for 72.5% of all OACs prescribed in newly diagnosed AF patients. OAC initiation was associated with male gender, age 65-74 years, few comorbidities and increased risk of stroke. Since 2010, more incident AF patients in Denmark were initiated o...Continue Reading

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.
