Masked uncontrolled hypertension (MUCH) is at higher cardiovascular risk than controlled hypertension (CH). In previous studies, patients with MUCH were considered as a unique group though those receiving ≤2 drugs could be defined as having nonresistant MUCH (NRMUCH) and those receiving ≥3 drugs as having resistant MUCH (RMUCH). The aim of this study was to assess the prognostic value of NRMUCH and RMUCH detected by ambulatory blood pressure (BP) monitoring. Cardiovascular risk was evaluated in 738 treated hypertensive patients with normal clinic BP. Patients were classified as having CH or MUCH if daytime BP < or ≥ 135/85 mmHg, respectively, regardless of nighttime BP, or CH or MUCH if 24-h BP < or ≥ 130/80 mmHg, respectively, regardless of daytime or nighttime BP. By daytime or 24-h BP, the authors detected 523 (71%), 178 (24%), and 37 (5%) or 463 (63%), 231 (31%), and 44 (6%) patients with CH, NRMUCH, and RMUCH, respectively. During the follow-up (median 10 years), 148 events occurred. After adjustment for covariates, compared to CH, the hazard ratio (HR), 95% confidence interval (CI), for cardiovascular events was 1.81, 1.27-2.57, and 2.99, 1.73-5.16, in NRMUCH and RMUCH defined by daytime BP, respectively, and 1.58, 1.12-2.23, and 2.21, 1.27-3.82, in NRMUCH and RMUCH defined by 24-h BP, respectively. If RMUCH was compared with NRMUCH, the risk tended to be higher in RMUCH but did not attain statistical significance (P = .08 and P = .23 by daytime and 24-h BP thresholds, respectively). In conclusion, both NRMUCH and RMUCH are at increased cardiovascular risk than CH., (© 2022 The Authors. The Journal of Clinical Hypertension published by Wiley Periodicals LLC.)

The aim of this study was to perform a meta-analysis of studies evaluating the association of clinic and daytime, nighttime, and 24-h blood pressure with the occurrence of new-onset atrial fibrillation. We conducted a literature search through PubMed, Web of science, and Cochrane Library for articles evaluating the occurrence of new-onset atrial fibrillation in relation to the above-mentioned blood pressure parameters and reporting adjusted hazard ratio and 95% confidence interval. We identified five studies. The pooled population consisted of 7224 patients who experienced 444 cases of atrial fibrillation. The overall adjusted hazard ratio (95% confidence interval) was 1.05 (0.98-1.13), 1.19 (1.11-1.27), 1.18 (1.11-1.26), and 1.23 (1.14-1.32), per 10-mmHg increment in clinic, daytime, nighttime, and 24-h systolic blood pressure, respectively. The degree of heterogeneity of the hazard ratio estimates across the studies (Q and I-squared statistics) were minimal. The results of this meta-analysis strongly suggest that ambulatory systolic blood pressure prospectively predicts incident atrial fibrillation better than does clinic systolic blood pressure and that daytime, nighttime, and 24-h systolic blood pressure are similarly associated with future atrial fibrillation., (© 2021 The Authors.

The aim of this study was to evaluate the influence of clinic and ambulatory blood pressure (BP) on the occurrence of new-onset atrial fibrillation (AF) in treated hypertensive patients. We studied 2135 sequential treated hypertensive patients aged >40 years. During the follow-up (mean 9.7 years, range 0.4-20 years), 116 events (new-onset AF) occurred. In univariate analysis, clinic, daytime, nighttime, and 24-h systolic BP were all significantly associated with increased risk of new-onset AF, that is, hazard ratio (95% confidence interval) per 10 mm Hg increment 1.22 (1.11-1.35), 1.36 (1.21-1.53), 1.42 (1.29-1.57), and 1.42 (1.26-1.60), respectively. After adjustment for various covariates in multivariate analysis, clinic systolic BP was no longer associated with increased risk of new-onset AF, whereas daytime, nighttime, and 24-h systolic BP remained significantly associated with outcome, that is, hazard ratio (95% confidence interval) per 10 mm Hg increment 1.09 (0.97-1.23), 1.23 (1.10-1.39), 1.16 (1.03-1.31), and 1.22 (1.06-1.40), respectively. Daytime, nighttime, and 24-h systolic BP are superior to clinic systolic BP in predicting new-onset AF in treated hypertensive patients. Future studies are needed to evaluate whether a better control of ambulatory BP might be helpful in reducing the occurrence of new-onset AF., (© 2020 The Authors.

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., (© 2020 Wiley Periodicals LLC.)

We investigated the prognostic value of morning surge (MS) of blood pressure (BP) in middle-aged treated hypertensive patients. The occurrence of a composite end point (coronary events, stroke, and heart failure requiring hospitalization) was evaluated in 1073 middle-aged treated hypertensive patients (mean age 49 years). Patients with preawakening MS of BP above the 90th percentile (27/20.5 mm Hg for systolic/diastolic BP) were defined as having high MS of BP. During the follow-up (mean 10.9 years), 131 cardiovascular events occurred. After adjustment for various covariates, including known risk markers and ambulatory BP parameters, patients with high MS of systolic BP (hazard ratio 1.81, 95% confidence interval 1.10-2.96) and those with high MS of diastolic BP (hazard ratio 1.98, 95% confidence interval 1.19-3.28) were at higher cardiovascular risk than those with normal MS. In middle-aged treated hypertensive patients, high MS of systolic and diastolic BP is independently associated with increased cardiovascular risk., (©2019 Wiley Periodicals, Inc.)
