Comparison and Implication of the Contemporary Blood Pressure Guidelines on Korean Population.

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.
