Objective Few studies have evaluated survival of Takayasu's arteritis (TAK; M31.4) in Korea. The purpose of this study was to assess the survival rate (SR) and causes of death for TAK. Methods Newly diagnosed TAK data (N = 2731) were collected from the National Health Insurance Service in Korea from 2006 through 2017. The Kaplan‐Meier method was used. Korean death data was used from 2006 through 2018. Results The mean age was 48.1 (±16.9) years. The proportion of female patients was 74.4%. The most common cause of death in TAK was diseases of the circulatory system. The 1‐, 3‐, 5‐, and 10‐year SRs were 97.5%, 94.7%, 91.7%, and 84.7%, respectively. The 1‐, 3‐, 5‐, and 10‐year SRs by gender were 97.8%, 95.6%, 92.9%, and 86.3%, respectively, among females and 96.8%, 92.2%, 88.4%s and 79.7%, respectively, among males ( P < .001). Conclusions The overall 10‐year SR was about 85%. The 10‐year SR in males was lower than that in females. The most common cause of death in TAK was diseases of the circulatory system.
