Sacubitril/valsartan effects on arrhythmias and left ventricular remodelling in heart failure: An observational study.

Aims: Conflicting results have been reported in the literature on the potential antiarrhythmic effect of sacubitril/valsartan in heart failure patients with reduced ejection fraction (HFrEF). The objectives of this study were: 1- to evaluate the long term effects of sacubitril/valsartan on arrhythmic burden in HFrEF patients; 2- to evaluate the correlation between the reduction of premature ventricular complexes during f-up and reverse remodelling.

Methods: We identified 255 consecutive HFrEF patients treated with sacubitril/valsartan between March 2017 and May 2020 and followed by the Heart Failure and Cardiac Transplant Unit of IRCCS San Matteo Hospital in Pavia (Italy).

Genetics in Probands With Idiopathic Ventricular Fibrillation: A Multicenter Study.

Background: Different genes have been associated with idiopathic ventricular fibrillation (IVF); however, there are no studies correlating genotype with phenotype.

Objectives: The aim of this study was to define the genetic background of probands with IVF using large gene panel analysis and to correlate genetics with long-term clinical outcomes.

Methods: All consecutive probands with a diagnosis of IVF were included in a multicenter retrospective study.
