ABSTRACT
BACKGROUND: Frailty is common in adults with end-stage heart failure receiving a left ventricular assist device (LVAD). Short-term studies show frailty reversal post-LVAD. Little is known about long-term frailty and how frailty relates to key LVAD outcomes, including depression, quality of life (QoL), and cognition beyond 6 months.
OBJECTIVE: The purpose of this study was to examine physical frailty, depression, QoL, and cognition from pre-LVAD implantation to 3, 6, and 12 months post-LVAD implantation.
METHODS: Clinical data and measures of physical frailty, depression, QoL, and cognition pre- and post-LVAD were extracted from an existing institutional database. Descriptive statistics and tests for statistical significance were used to describe and compare changes over time. Frailty trajectories were identified to describe physical frailty from pre-LVAD to 12 months post-LVAD.
RESULTS: The sample (n = 46) was predominantly male (76%), with a mean age of 64.7 ± 11 years, and over half (n = 25) were physically frail. Physical frailty was reduced by nearly half at 12 months. Frailty, depression, and QoL significantly improved at all time points (P < .001). Improvements in cognition did not reach statistical significance. Recipients of LVAD without improvement in frailty exhibited worse depression, QoL, and cognition scores at 12 months compared with those not frail pre-LVAD or no longer frail post-LVAD implantation.
CONCLUSION: Some recipients of LVADs experienced physical frailty reversal with benefits sustained long-term. Those without improvement recorded worse long-term patient-reported outcomes. Identifying factors that predict physical frailty response to LVAD implantation is a key area of future research.
