SGLT2i reduce arrhythmic events in heart failure patients with cardiac implantable electronic devices.

Background: Sodium glucose cotransporter 2 inhibitors (SGLT2i) represent one of the four pillars of heart failure (HF) pharmacological therapy.

Objective: The study aims to clarify SGLT2i antiarrhythmic effect on patients with HF with reduced ejection fraction (HFrEF) in terms of atrial and ventricular arrhythmias (AAs and VAs) reduction.

Methods: HFrEF carriers of implantable cardioverter defibrillator (ICD) or cardiac resynchronization therapy defibrillator (CRT-D) followed by remote monitoring of Policlinico Umberto I of Rome for 1 year before and after SGLT2i therapy initiation were enrolled in the study.
