Masked and white coat hypertension, the double trouble of large arteries: A systematic review and meta-analysis.

ABSTRACT: Arterial damage of large arteries, addressed as c-f PWV, is recognized as independent predictor for future cardiovascular disease. The aim of this study was to systematically investigate the association of the four hypertension phenotypes with carotid-femoral pulse wave velocity (c-f PWV), in untreated patients. PubMed and Cochrane Library were searched to identify studies comparing c-f PWV levels between normotensives, sustained hypertensives, white-coat hypertensives (WCH), and masked hypertensives (MH). Meta-analysis was performed to compare the difference c-f PWV levels between these groups. Newcastle-Ottawa quality assessment scale for cross-sectional studies was used to assess study quality. MH and WCH patients had significantly increased c-f PWV values compared to the normotensive groups (d = 0.96 m/s, 95% CI: 0.49-1.42; I2 = 85%, P < .01 for MH and d = 0.85 m/s, 95% CI: 0.48-1.22; I2 = 89%, for WCH). Moreover, the sustained hypertensive population was found to have significantly increased values of c-f PWV compared to MH (d = -0.70 m/s, 95% CI: -0.87 to -0.54; I2 = 12%, P = .33) but not compared to WCH population (d = -0.75 m/s, 95% CI: -1.52-0.02; I² = 96%,). Finally, there was no significant difference between MH and WCH population (d = 0.06 m/s, 95% CI: -1.04 to 1.15; I² = 96%,). MH and WCH population may have increased values of c-f PWV compared to the normotensive group. These results demonstrate that these phenotypes are not clinically innocent, in the untreated population.

Project description:Abstract Aims The detection of white-coat hypertension/white-coat uncontrolled hypertension (WCH/WUCH) with out-of-office blood pressure (BP) monitoring is time- and resource-consuming. We aim to develop a machine learning (ML)-derived prediction model based on the characteristics of patients from a single outpatient visit. Methods and results Data from two cohorts in Taiwan were used. Cohort one (970 patients) was used for development and internal validation, and cohort two (464 patients) was used for external validation. WCH/WUCH was defined as an office BP of ≥140/90 mmHg and daytime ambulatory BP of <135/85 mmHg in treatment-naïve or treated individuals. Logistic regression, random forest (RF), eXtreme Gradient Boosting, and artificial neural network models were trained using 26 patient parameters. We used SHapley Additive exPlanations values to provide explanations for the risk factors. All models achieved great area under the receiver operating characteristic curve (AUROC), specificity, and negative predictive value in both validations (AUROC = 0.754–0.891; specificity = 0.682–0.910; negative predictive value = 0.831–0.968). The RF model was the best performing (AUROC = 0.884; sensitivity = 0.619; specificity = 0.887; negative predictive value = 0.872; accuracy = 0.819). The five most influential features of the RF model were office diastolic BP, office systolic BP, current smoker, estimated glomerular filtration rate, and fasting glucose level. Conclusion Our prediction models achieved good performance, underlining the feasibility of applying ML models to outpatient populations for the diagnosis of WCH and WUCH. Further validation with other prospective data sets should be considered in the future. Graphical Abstract Graphical Abstract Two cohorts were used for model development after splitting and external validation respectively. With oversampled training set, four algorithms were developed through the process of feature ranking with SHapley Additive exPlantions values, feature selection, and threshold tuning under five-fold cross-validation. Models were then evaluated by variant metrics. Present study demonstrated the feasibility of applying machine learning models to outpatient population for the identify of white-coat hypertension and white-coat uncontrolled hypertension.

Project description:BackgroundMultiple epidemiological studies from Europe and Asia have demonstrated increased cardiovascular risks associated with isolated elevation of home blood pressure (BP) or masked hypertension (MH). Previous studies have not addressed cardiovascular outcomes associated with MH and white-coat hypertension (WCH) in the general population in the United States.ObjectivesThe goal of this study was to determine hypertensive target organ damage and adverse cardiovascular outcomes associated with WCH (high clinic BP, ≥140/90 mm Hg; normal home BP, <135/85 mm Hg), MH (high home BP, ≥135/85 mm Hg; normal clinic BP, <140/90 mm Hg), and sustained hypertension (high home and clinic BP) in the DHS (Dallas Heart Study), a large, multiethnic, probability-based population cohort.MethodsAssociations among WCH, MH, sustained hypertension, and aortic pulsed wave velocity by magnetic resonance imaging; urinary albumin-to-creatinine ratio; and cystatin C were evaluated at study baseline. Then, associations between WCH and MH with incident cardiovascular outcomes (coronary heart disease, stroke, atrial fibrillation, heart failure, and cardiovascular death) over a median follow-up period of 9 years were assessed.ResultsThe study cohort comprised 3,027 subjects (50% African Americans). The sample-weighted prevalence rates of WCH and MH were 3.3% and 17.8%, respectively. Both WCH and MH were independently associated with increased aortic pulsed wave velocity, cystatin C, and urinary albumin-to-creatinine ratio. Both WCH (adjusted hazard ratio: 2.09; 95% confidence interval: 1.05 to 4.15) and MH (adjusted hazard ratio: 2.03; 95% confidence interval: 1.36 to 3.03) were independently associated with higher cardiovascular events compared with the normotensive group, even after adjustment for traditional cardiovascular risk factors.ConclusionsIn a multiethnic U.S. population, both WCH and MH were independently associated with increased aortic stiffness, renal injury, and incident cardiovascular events. Because MH is common and associated with an adverse cardiovascular profile, home BP monitoring should be routinely performed among U.S. adults.
