start of 1:1-Block public summary

Brief Summary in Lay Language

The purpose of this study is to assess whether normal endothelial function in patients with
Atrial Fibrillation undergoing ablation procedure increases the chances of a favorable
clinical outcome and maintaining sinus rhythm following ablation

start of 1:1-Block scientific synopsis

Brief Summary in Scientific Language

In the recent years, increasing evidence is linking inflammation to AFib. In addition, it
has been shown that ablation improves endothelial function, suggesting that AFib might be
associated with the etiology of endothelial dysfunction.

The objective of this study is to assess endothelial function using Endo-PAT2000 and its
correlation to clinical outcome following ablation of patients with Atrial Fibrillation
