Improvement in quality of life with sacubitril/ /valsartan in cardiac resynchronization non-responders: The RESINA (RESynchronization plus an Inhibitor of Neprilysin/Angiotensin) registry.

Background: Clinical management of cardiac resynchronization therapy (CRT) non-responders is difficult, and their prognosis is poor. The aim of the present study was to evaluate whether treatment with sacubitril/valsartan can improve quality of life (QoL) parameters in these patients.

Methods: Thirty five non-responders to CRT were included (75 ± 7 years, 28% females, mean left ventricular ejection fraction 28 ± 8%, 54% non-ischemic cardiomyopathy) with maximally optimized drug therapy and New York Heart Association class II-III.
