Predictors of Positive Response to Resynchronization Therapy in Patients with Recurrent Episodes of Acutely Decompensated Advanced Heart Failure

Abstract

Background: In just a few years, cardiac resynchronization therapy (CRT) has emerged as a key player in the treatment of advanced heart failure (HF). However, approximately 30% of patients with CRT device implantation do not achieve a favorable response. The purpose of the present study was to identify clinical, electrocardiographic, and echocardiographic predictors of a positive response to biventricular pacing in patients with advanced decompensated HF.
