The authors assessed the prognostic value of daytime and nighttime blood pressure (BP) in adult (≤65 years) or old (> 65 years) women or men with treated hypertension. Cardiovascular outcomes were evaluated in 2264 patients. During the follow‐up (mean 10 years), 523 cardiovascular events occurred. After adjustment for covariates, both daytime and nighttime systolic BP were always associated with outcomes, that is, hazard ratio (95% confidence interval per 10 mm Hg increment) 1.22 (1.04‐1.43) and 1.20 (1.04‐1.37), respectively, in adult women, 1.30 (1.18‐1.43) and 1.21 (1.10‐1.33), respectively, in adult men, 1.21 (1.10‐1.33) and 1.18 (1.07‐1.31), respectively, in old women, and 1.16 (1.01‐1.33) and 1.28 (1.14‐1.44), respectively, in old men. When daytime and nighttime systolic BP were further and mutually adjusted, daytime and nighttime BP had comparable prognostic value in adult and old women, daytime BP remained associated with outcomes in adult men (hazard ratio 1.40, 95% confidence interval 1.13‐1.74 per 10 mm Hg increment), and nighttime BP remained associated with outcomes in old men (hazard ratio 1.35, 95% confidence interval 1.11‐1.64 per 10 mm Hg increment). Daytime and nighttime systolic BP have similar prognostic impact in adult and old women with treated hypertension, whereas daytime BP is a stronger predictor of risk in adult men and nighttime BP is a stronger predictor of risk in old men.
