Health-related quality of life and readmission of patients with cardiovascular disease in South Korea.

AIMS: The purpose of this study was to investigate the health-related quality of life (HRQOL) of patients with cardiovascular disease and its relationship to hospital readmission. METHODS: The cross-sectional study used data from 1037 adults aged ⩾19 years diagnosed with myocardial infarction or angina pectoris. Raw data were obtained from the fourth to sixth Korea National Health and Nutrition Examination Survey (2007-2014). RESULTS: Readmission was found to be associated with age, living status, education level, unemployment, individual income level, stroke, osteoarthritis, diabetes, depression, low stress level, walking days per week, and activity limitations due to cardiovascular disease. CONCLUSION: In summary, readmission was related to HRQOL among patients with myocardial infarction. Interventions that consider efforts to reduce readmission through improved diagnosis and development of systematic management of cardiovascular disease symptoms are required.
