BACKGROUND AND PURPOSE: We explored the new BP thresholds and their impact on first-ever stroke risk determinations.
RESULTS: During a mean following-up period of 21.85 years, 638 first-ever strokes occurred among 3906 participants. After adjusting for covariates, the hazard ratios for ischemic stroke (IS) in men aged <60 years were significant higher in participants with elevated BP, stage 1 hypertension, and stage 2 hypertension than normal BP (all P<0.05); an increased risk of intracerebral hemorrhage (ICH) was also observed for those with stage 2 hypertension. Similarly, in women aged, the risk of stroke increased for those with stage 2 hypertension both in <60 years and in ≥60 years. Moreover, more than 60% of incident strokes were attributed to systolic BP (SBP) ≥120mmHg and diastolic BP (DBP) <80mmHg in men aged <60 years.
CONCLUSIONS: Elevated BP increases the risk of developing stroke, particularly in the absence of routine BP measurements and hypertension treatment. A strict BP management target (SBP, <120 mmHg; DBP, <80 mmHg) should be adopted for young and middle-aged men.
METHODS: This population-based cohort study was conducted between October 1991 and January 2018. The association of BP categories, defined by the 2017 ACC/AHA BP guideline, with first-ever stroke risk was assessed using Cox regression models.
