BACKGROUND: There is a paucity of research describing health-related quality of life (HRQOL) in older adults considered for advanced heart failure surgical therapies. Using data from our SUSTAIN-IT (Sustaining Quality of Life of the Aged: Heart Transplant or Mechanical Support) study, we aimed to compare HRQOL among 3 groups of older (60– 80 years) patients with heart failure before heart transplantation (HT) or long-term mechanical circulatory support (MCS) and identify factors associated with HRQOL: (1) HT candidates with MCS, (2) HT candidates without MCS, or (3) candidates ineligible for HT and scheduled for long-term MCS. METHODS AND RESULTS: Patients from 13 US sites completed assessments, including self-reported measures of HRQOL (EuroQol-5 Dimension Questionnaire, Kansas City Cardiomyopathy Questionnaire–12), depressive symptoms (Personal Health Questionnaire– 8), anxiety (State-Trait Anxiety Inventory– state form), cognitive status (Montreal Cognitive Assessment), and performance-based measures (6-minute walk test and 5-m gait speed). Analyses included ANOVA, χ2 tests, Fisher’s exact tests, and linear regression. The sample included 393 patients; the majority of patients were White men and married. Long-term MCS candidates (n=154) were significantly older and had more comorbidities and a higher New York Heart Association class than HT candidates with MCS (n=118) and HT candidates without MCS (n=121). Long-term MCS candidates had worse HRQOL than HT candidates with and without MCS (EQ-5D visual analog scale scores, 46±23 versus 68±18 versus 54±23 [P<0.001] and Kansas City Cardiomyopathy Questionnaire–12 overall summary scores, 35±21 versus 60±21 versus 49±22 [P<0.001], respectively). In multivariable analyses, lower 6-minute walk distance, higher New York Heart Association class, depressive symptoms, and not being an HT candidate with MCS were significantly associated with worse overall HRQOL. CONCLUSIONS: Our findings demonstrate important differences in overall and domain-specific HRQOL of older patients with heart failure before HT or long-term MCS. Understanding HRQOL differences may guide decisions toward more appropriate and personalized advanced heart failure therapies.
