Factors affecting quality of life in Korean patients with chronic heart failure

Abstract

AIM: Poor health-related quality of life (HRQOL) in patients with chronic heart failure (CHF) may be one of the most common predictors of mortality and rehospitalization. This study was conducted to identify factors affecting HRQOL in Korean patients with CHF using two HRQOL measurements. METHODS: The study included a sample of 114 patients. HRQOL was measured by the Minnesota Living with Heart Failure Questionnaire (MLHFQ) and the World Health Organization's Quality of Life Instrument - Short Version (WHOQOL-BREF). Multiple regression analyses were performed to analyze the relationship between the factors and HRQOL. RESULTS: Significant correlations were found between MLHFQ and WHOQOL-BREF in total and component scores, with the two exceptions of WHOQOL-BREF psychological and MLHFQ physical or total. The perceived economic status, functional status, and sex were factors identified as having an effect on HRQOL. CONCLUSION: The MLHFQ was better able to differentiate sex, comorbidity, and functional status. Further studies are needed to implement cost-effective nursing interventions for patients with CHF to improve their HRQOL.
