Better Survival in Morbidly Obese Patients with Atrial Fibrillation Treated with Non-vitamin K-dependent Oral Anticoagulants.

Background: The efficacy and safety of non-vitamin K-dependent anticoagulants (NOAC) are not well investigated in the obese population, and fixed dosing could lead to under-anticoagulation. Our objective was to evaluate the effect of obesity on anticoagulation outcomes and survival in non-valvular atrial fibrillation (AF) patients.

Methods: We enrolled 755 patients who required anticoagulation for AF from 2015 to 2016.

HAS-BLED Score for Prediction of Bleeding and Mortality After Transcatheter Aortic Valve Replacement.

Introduction: Bleeding after transcatheter aortic valve replacement (TAVR) is associated with increased mortality. The predictive value of the HAS-BLED score in TAVR patients is still to be evaluated. We assessed the value of the HAS-BLED score to predict in-hospital bleeding and mortality after TAVR and the impact of diferent renal impairment definitions on the predictive value of the score system.
