Background: In patients with heart failure (HF), good health-related quality of life (HRQOL) is as valuable as, or more valuable than, longer survival. However, HRQOL is remarkably poor, and HF symptoms are strongly associated with poor HRQOL. Yet, the multidimensional, modifiable predictors have been rarely examined. Objective: The aim of this study was to examine the baseline psychosocial, behavioral, and physical predictors of HF symptoms and HRQOL at 12 months and the mediator effect of HF symptoms in the relationship between depressive symptoms and HRQOL. Methods: We collected data from 94 patients with HF (mean ± SD age, 58 ± 14 years). Data included sample characteristics, depressive symptoms, perceived control, social support, New York Heart Association (NYHA) functional class, medication adherence, sodium intake, self-care management, and HF symptoms at baseline, as well as HF symptoms and HRQOL at 12 months. Multiple regression analyses were performed to address the purpose. Results: Baseline depressive symptoms (P < .001), medication adherence (P = .010), sodium intake (P = .032), and NYHA functional class (P = .040) significantly predicted 12-month HF symptoms, controlling for covariates (F = 7.363, R² = 47%, P < .001). Baseline medication adherence (P = .001), NYHA functional class (P < .001), and HF symptoms (P = .013) significantly predicted 12-month HRQOL (F = 10.701, R² = 59%, P < .001). Baseline HF symptoms fully mediated the relationship between baseline depressive symptoms and 12-monthHRQOL. Conclusion: Symptoms of HF and HRQOL could be improved by targeting multidimensional, modifiable predictors, such as self-care, depressive symptoms, and NYHA functional class. [ABSTRACT FROM AUTHOR]

Background: A better understanding is needed of the burdens and benefits of left ventricular assist device (LVAD) implantation on patients' physical, mental, and social well-being. The purpose of this report was to evaluate the validity of Patient-Reported Outcomes Measurement Information System (PROMIS) measures for LVAD patients and to estimate clinically important score differences likely to have implications for patient treatment or care. Methods: Adults from 12 sites across all US geographic regions completed PROMIS measures ≥3 months post-LVAD implantation. Other patient-reported outcomes (eg, Kansas City Cardiomyopathy Questionnaire-12 item), clinician ratings, performance tests, and clinical adverse events were used as validity indicators. Criterion and construct validity and clinically important differences were estimated with Pearson correlations, ANOVA methods, and Cohen d effect sizes. Results: Participants' (n=648) mean age was 58 years, and the majority were men (78%), non-Hispanic White people (68%), with dilated cardiomyopathy (55%), long-term implantation strategy (57%), and New York Heart Association classes I and II (54%). Most correlations between validity indicators and PROMIS measures were medium to large (≥0.3; p <0.01). Most validity analyses demonstrated medium-to-large effect sizes (≥0.5) and clinically important differences in mean PROMIS scores (up to 14.8 points). Ranges of minimally important differences for 4 PROMIS measures were as follows: fatigue (3–5 points), physical function (2–3), ability to participate in social roles and activities (3), and satisfaction with social roles and activities (3–5). Conclusions: The findings provide convincing evidence for the relevance and validity of PROMIS physical, mental, and social health measures in patients from early-to-late post-LVAD implantation. Findings may inform shared decision-making when patients consider treatment options. Patients with an LVAD, their caregivers, and their clinicians should find it useful to interpret the meaning of their PROMIS scores in relation to the general population, that is, PROMIS may help to monitor a return to normalcy in everyday life.

Purpose: Patients with heart failure (HF) have notably poor health-related quality of life (HRQOL). A 5-point improvement in HRQOL is associated with reduction in hospitalization and mortality rates. Heart failure symptoms are associated with poor HRQOL, but little is known about whether changes in HF symptoms lead to changes in HRQOL over time. Therefore, we examined the association of changes in HF symptoms with changes in overall, physical, and emotional aspects of HRQOL over a 12-month period, controlling for typical covariates., Methods: Data on HF symptoms and HRQOL (Minnesota Living Heart Failure questionnaire) were collected from 94 patients with HF (mean age, 58 years; 58.5% female) at baseline and 12-month follow-up. Psychosocial factors (depressive symptoms, perceived control, and social support), behavioral factors (medication adherence and sodium intake), sociodemographic and clinical factors (age, comorbidities, and body mass index), and a physical factor (functional status) were collected at baseline. Multiple and logistic regression analyses were used to analyze the data., Results: In complete models, changes in HF symptoms were associated with changes in the total HRQOL (P < .001) and the physical (P < .001) and emotional (P < .001) aspects of HRQOL over 12 months, controlling for all the factors. Changes in HF symptoms were significantly associated with the likelihood of at least a 5-point improvement in HRQOL (P = .001), controlling for covariates., Conclusions: Improvement in HF symptoms was associated with improvement in HRQOL over 12 months. Thus, development and delivery of interventions that target improvement in HF symptoms may improve HRQOL.
