Core Tip
Core tip: In atrial fibrillation, renal dysfunction entails more adverse events. Limited data exist on the performance and prognostic value of the re-expressed Modification of Diet in Renal Disease equation vs the new Chronic Kidney Disease Epidemiology Collaboration equation in atrial fibrillation. We compared the performance of both equations at predicting major outcomes in patients with non-valvular atrial fibrillation. The study encouraged the use of the new equation as it decreased the prevalence of patients with renal dysfunction, in a real world cohort of patients with non-valvular atrial fibrillation and at the same time showed similar prognostic impact like the re-expressed equation.
