The purpose of this pilot study is to assess the feasibility of a double-blind, randomized placebo-controlled trial of semaglutide 2.4 mg subcutaneously once weekly on top of standard care compared to standard care alone.

The SOCRATES-AF pilot study is a prospective, parallel-group, double-blind, randomized controlled trial in patients with paroxysmal or early persistent atrial fibrillation and overweight and obesity. The primary objective is to assess the feasibility of a double-blind, randomized placebo-controlled trial of semaglutide 2.4 mg subcutaneously (s.c.) once weekly on top of current standard care (lifestyle and risk factor management, oral anticoagulant and rate control therapy) versus current standard care alone in overweight or obese patients with symptomatic paroxysmal or early persistent AF. To assess recurrences of atrial fibrillation all participants will receive an implantable cardiac monitor.
