Risk assessment and comparative effectiveness of left ventricular assist device and medical management in ambulatory heart failure patients results from the ROADMAP Study

Abstract Background Data for left ventricular assist devices (LVADs) in patients with noninotrope-dependent heart failure (HF) are limited. Objectives The goal of this study was to evaluate HeartMate II (HMII) LVAD support versus optimal medical management (OMM) in ambulatory New York Heart Association functional class IIIB/IV patients meeting indications for LVAD destination therapy but not dependent on intravenous inotropic support. Methods This was a prospective, multicenter (N = 41), observational study of 200 patients (97 LVAD, 103 OMM). Entry criteria included ≥1 hospitalization for HF in the last 12 months and 6-min walk distance (6MWD)  Results LVAD patients were more severely ill, with more patients classified as Interagency Registry for Mechanically Assisted Circulatory Support profile 4 (65% LVAD vs. 34% OMM; p  Conclusions Survival with improved functional status was better with HMII LVAD compared with OMM. Despite experiencing more frequent adverse events, LVAD patients improved more in HRQol and depression. The results support HMII use in functionally limited, noninotrope-dependent HF patients with poor HRQoL.
