Abstract


Background and Objectives: This study compared the potential impacts of the 2017 American College of Cardiology/American Heart Association (ACC/AHA) and the 2018 Korean Society of Hypertension (KSH) guidelines on prevalence of hypertension, recommended antihypertensive treatment, and achievement of target blood pressure (BP) in Korean population.

Methods: We analyzed the 2007?2017 Korea National Health and Nutrition Examination Survey data to calculate guideline-specific hypertension prevalence and treatment implications on 59,767 adults aged 20 years or older by sex and age.

Results: The prevalence of hypertension was markedly higher 46.3% by the ACC/AHA guideline due to the lowered BP cutoff than 25.9% by the KSH guideline; the increase was most pronounced in young adults. Yet, there was only a marginal 1.6% increase in the percentage of adults suggested pharmacological approach by the ACC/AHA guideline, but selectively in the older subgroups. Overall, 45.6% of Korean adults treated for hypertension failed to meet BP goal according to the KSH guideline; the underachievement extended to 61.7% of participants according to the ACC/AHA guideline.

Conclusions: The lowered BP threshold, 130/80 mmHg, by the 2017 ACC/AHA guideline, in conjuncture with 10-year risk calculation largely driven by age, would increase pharmacological treatment preferentially in very old individuals, while increasing prevalence and uncontrolled rate mostly in younger subgroups. Adoption of lower BP cutoff to the KSH guideline would require validated cardiovascular disease risk assessment tools accounting for risk distributions specific to Korean population.
