Abstract

Current data for atrial fibrillation (AF) and stroke are predominantly derived from North American and European patients. Although the burden of AF is high in Latin America (LA), little is known about current management of AF in the region. We aimed to assess the consistency of efficacy and safety outcomes associated with dabigatran etexilate (DE) versus warfarin in patients with AF in LA from the RE-LY (Randomised Evaluation of Long-Term Anticoagulant Therapy) trial. Data from 956 LA patients and 17 157 non-LA patients were included in this analysis. χ2 test and Cox proportional regression analysis were performed. The primary efficacy outcome included all strokes or systemic embolism (SE). Main safety outcome was major bleeding. LA patients were more often female, had higher proportion of permanent AF and lower creatinine clearance, among other characteristics. Vitamin K antagonist use at randomisation and time in therapeutic range were lower in LA than in non-LA patients (44% vs 63%, p<0.001; and 61.3±22.6% vs 64.6±19.6%, p=0.015, respectively). Efficacy endpoints were 0.91% versus 1.68% for DE 150 mg twice daily versus warfarin, respectively. Stroke/SE risk was lower in LA patients treated with DE 150 mg twice daily compared...Continue Reading

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.

Arrhythmia

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.
