BACKGROUND: Factors related to health-related quality of life (HRQOL) 2 years after left ventricular assist device (LVAD) implantation are unknown. We sought to determine whether preimplant intended goal of LVAD therapy (heart transplant candidate [short-term group], uncertain heart transplant candidate [uncertain group], and heart transplant ineligible [long-term group]) and other variables were related to HRQOL 2 years after LVAD implantation. METHODS AND RESULTS: Our LVAD sample (n=1620) was from INTERMACS (Interagency Registry for Mechanically Assisted Circulatory Support). Using the EuroQol-5 Dimension Questionnaire (EQ-5D-3L), a generic HRQOL measure, and the Kansas City Cardiomyopathy Questionnaire (KCCQ-12), a heart failure– specific HRQOL measure, multivariable linear regression modeling was conducted with the EQ-5D-3L Visual Analog Scale (VAS) score and KCCQ-12 overall summary score (OSS) as separate dependent variables. Two years after LVAD implant, the short-term group had a significantly higher mean VAS score versus the uncertain and long-term groups (short-term: 75.18 [SD, 20.62]; uncertain: 72.27 [SD, 20.33]; long-term: 70.87 [SD, 22.09], P=0.01); differences were not clinically meaningful. Two-year mean scores did not differ by group for the KCCQ-12 OSS (short-term, 67.85 [SD, 20.61]; uncertain, 67.79 [SD, 19.31]; long-term, 67.08 [SD, 21.49], P=0.80). Factors associated with a worse VAS score 2 years postoperatively (n=1205) included not working; not having a short-term LVAD; and postoperative neurological dysfunction, greater health-related stress, coping poorly, less VAD self-care confidence, and less satisfaction with VAD surgery, explaining 28% of variance (P<0.001). Factors associated with a worse KCCQ-12 OSS 2 years postopera-tively (n=1250) included not working; history of high body mass index and diabetes mellitus; and postoperative renal dysfunc-tion, greater health-related stress, coping poorly, less VAD self-care confidence, less satisfaction with VAD surgery, and regret regarding VAD implantation, accounting for 36% of variance (P<0.001). CONCLUSIONS: Factors related to HRQOL 2 years after LVAD implantation include demographic, clinical, and psychological variables.
