Objectives This study aimed to identify the predictors of health-related quality of life (HRQoL) in Korean adults with cardiovascular disease (CVD). Methods This was a cross-sectional study with a stratified multistage probability sampling design. Data from the 2016 to 2019 Korea National Health and Nutrition Examination Survey (n=32,379) were used. Among the participants aged 19 years or older (n=25,995), 1,081 patients with CVD were extracted after excluding those with missing data and those who had cancer. The participants’ HRQoL was measured using the three-level EuroQoL Group’s five-dimension questionnaire (EQ-5D) scale. Data were analyzed using the t-test, one-way analysis of variance, and general linear regression for complex samples. Results The most potent predictors of HRQoL in Korean adults with CVD were limited activity (β=−0.103, p<0.001), poor perceived health (β=−0.089, p<0.001), depression (β=−0.065, p<0.01), low household income (β=−0.033, p<0.05), unemployment (β=−0.023, p<0.05), and older age (β=−0.002, p<0.01), which explained 37.2% of the variance. Conclusion Comprehensive interventions that address both physical and mental factors and social systems that provide financial help need to be implemented to improve the HRQoL of Korean adults with CVD.
