Assessing the diversity and determinants of health-related quality of life measures in patients with acute heart failure.

AIMS: Heart failure with reduced ejection fraction (HFrEF) significantly impacts health-related quality of life (HR-QoL). Existing HR-QoL questionnaires can show inconsistencies, potentially misrepresenting patient self-reports. This study examines the variation in HR-QoL measurement tools for HFrEF patients, identifying related determinants.

METHODS AND RESULTS: We retrospectively analysed 134 hospitalized patients with acute decompensated HFrEF at a Taiwanese tertiary centre's Heart Failure Post-Acute-Care (HF-PAC) programme. Participants completed the EuroQol-5 dimension (EQ-5D) questionnaire, the EQ-5D visual analogue scale (VAS), and the Minnesota Living with Heart Failure Questionnaire (MLHFQ). Utility values were obtained from the EQ-5D questionnaire. Demographic features were depicted using descriptive statistics, while multivariate regression was used to ascertain relationships between HR-QoL measurements and determinants. Average scores for EQ-5D, MLHFQ, EQ-5D utility, and VAS were 6.1 ± 1.6, 21.8 ± 21.3, 81.7 ± 27.0, and 59.5 ± 14.6, respectively. Significant correlations were observed among the three tools. The New York Heart Association functional class showed a notable association with all tool scores. Other associations encompassed EQ-5D with coronary artery disease, mineralocorticoid receptor antagonists, and the 6 min walk test; EQ-5D VAS with chronic kidney disease; and MLHFQ with age.

CONCLUSIONS: This study illuminates the variance in HR-QoL measurement tools for Taiwanese HFrEF patients. Using a range of these tools is beneficial in unveiling diverse determinants and approaching comprehensive patient-centred care. However, for a more precise HR-QoL assessment in Taiwanese HFrEF patients, recalibrating the EQ-5D-derived utility scores might be necessary, emphasizing the importance of patient-specific considerations within the HF-PAC programme.
