Key result
Application of the 2017 ACC/AHA high blood pressure guideline increased hypertension prevalence from 30.54% to 51.45%, while decreasing awareness from 44.33% to 26.31% and control rates from 13.04% to 2.72%.
Why the study?
The ACC/AHA updated high blood pressure guidelines in 2017, and the study aimed to evaluate their potential impact on hypertension prevalence, awareness, and control rates.
Does the 2017 ACC/AHA high blood pressure guideline alter hypertension prevalence, awareness, and control rates compared to previous guidelines in Chinese adults?

Does the 2017 ACC/AHA high blood pressure guideline alter hypertension prevalence, awareness, and control rates compared to previous guidelines in Chinese adults?
Application of the 2017 ACC/AHA hypertension guidelines in a Chinese cohort substantially increases the prevalence of hypertension while significantly lowering awareness and control rates, primarily by reclassifying younger, lower-risk individuals.
May reclassify many lower-risk Chinese adults as hypertensive; extends guideline impact data but leaves open optimal thresholds.
In 2017, the American College of Cardiology/American Heart Association (ACC/AHA) updated the Guideline of Prevention, Detection, Evaluation and Management and Management of High Blood Pressure (HBP) in Adults. The purpose of the current study was to evaluate the potential impact of the 2017ACC/AHA HBP guideline on hypertension prevalence, awareness, and control rates. The data were collected from Physical Examination Center of the Second Hospital of Hebei Medical University from January 2012 to December 2017 (N = 66 977), including demographic information and risk factors of hypertension. The hypertension prevalence, awareness, and control rates of people were evaluated according to the new guideline. Additionally, the factors related to hypertension prevalence were also assessed. According to previous HBP guideline, hypertension prevalence, awareness, and control rate were 30.54%, 44.33%, and 13.04%, respectively. However, when the 2017 ACC/AHA HBP guideline was introduced, the population with hypertension increased from 20 453 to 34 460, the hypertension prevalence rate increased from 30.54% to 51.45%, the awareness rate decreased from 44.33% to 26.31%, and the control rate declined from 13.04% to 2.72%. The most newly diagnosed hypertension patients were from the low-risk population with young age and without the above histories. The 2017ACC/AHA HBP guideline indicated that high hypertension prevalence rate still existed with a substantial increase, while the awareness and control rates were relatively lowered.

Zhou et al. (2019) conducted a cross-sectional in Hypertension (n=66,977). 2017 ACC/AHA high blood pressure guideline (BP ≥ 130/80 mm Hg) vs. Previous high blood pressure guideline (BP ≥ 140/90 mm Hg) was evaluated on Hypertension prevalence rate. Application of the 2017 ACC/AHA high blood pressure guideline increased hypertension prevalence from 30.54% to 51.45%, while decreasing awareness from 44.33% to 26.31% and control rates from 13.04% to 2.72%.
