Temporal trends in incidence, prevalence, and death of aortic stenosis in Korea: a nationwide population‐based study

Aims We aim to determine the temporal trends of incidence, prevalence, and death of aortic stenosis (AS, I35.0) in an East Asian population. Methods and results Data for 3773 patients who were newly diagnosed with AS from 2006 through 2017 were extracted from the National Health Insurance Service in Korea. The age‐standardized incidence rate, prevalence rate, and death rate, survival rate (SR), and death risk of AS were calculated. Overall, the mean (standard deviation) age of AS patients was 69.9 (15.3) years [66.2 (15.7) years for men and 72.7 (14.4) years for women (P = 0.007)], and the proportion of men was 42.7%. The proportion of AS patients ≥60 years old was 80% (71.8% in men and 86% in women, P
