Objectives: This study was carried out to investigate the impact of carotid artery stenosis on qualify of life in Korea.
Methods: A health scenario for each health states after undergoing carotid endarterectomy or carotid artery stent was developed, and Time Trade Off and EQ-5D-3L tools were used on 400 general population to examine health-related quality of life. In addition, the 5th Korea National Health and Nutrition Examination Survey (2012) and Stoke Registry of Seoul National University Bundang Hospital were utilized to find out quality of life of stroke and myocardial infarction, which are major complications of carotid artery stenosis.
Results: As a result of survey, utility weight for health states without major complications after undergoing carotid endarterectomy or carotid artery stent to treat carotid artery stenosis was 0.79 (±0.10), and utility weight was further decreased to 0.61 (±0.13) for health states after undergoing reoperation due to restenosis. These weight were similar to major complications, which showed utility of 0.77 (±0.05) for myocardial infarction and 0.79 (±0.06) for minor stroke. They were higher than weight of 0.41 (±0.48) for major stroke.
Conclusion: The results of this study showed that quality of life of carotid artery stenosis is similar to myocardial infarction and minor stroke. The meaning of this study is in that it produced Korean utility weight of each health states related to carotid artery stenosis which are regarded as critical data required for cost-utility analysis in the future.
