Abstract
Few investigators have compared health-related quality of life (HRQOL) in heart failure (HF) patients from different countries.The purposes of this study were to compare HRQOL between American (n = 87) and Taiwanese (n = 88) HF patients and to determine factors associated with HRQOL in both groups. In this cross-sectional survey, HRQOL was measured using the Minnesota Living with Heart Failure Questionnaire. American patients rated their HRQOL worse than Taiwanese patients did. Sociodemographics, disease severity, and symptom severity were associated with HRQOL, accounting for 42.4% of the variance in HRQOL in Americans and 57.3% in Taiwanese. Symptom severity was the most important predictor of HRQOL in both groups. Interventions targeting symptom severity could improve HF patients' HRQOL.
