Project description:ObjectiveWe investigated factors associated with masked and white-coat hypertension in a Swiss population-based sample.MethodsThe Swiss Kidney Project on Genes in Hypertension is a family-based cross-sectional study. Office and 24-hour ambulatory blood pressure were measured using validated devices. Masked hypertension was defined as office blood pressure<140/90 mmHg and daytime ambulatory blood pressure≥135/85 mmHg. White-coat hypertension was defined as office blood pressure≥140/90 mmHg and daytime ambulatory blood pressure<135/85 mmHg. Mixed-effect logistic regression was used to examine the relationship of masked and white-coat hypertension with associated factors, while taking familial correlations into account. High-normal office blood pressure was defined as systolic/diastolic blood pressure within the 130-139/85-89 mmHg range.ResultsAmong the 652 participants included in this analysis, 51% were female. Mean age (±SD) was 48 (±18) years. The proportion of participants with masked and white coat hypertension was respectively 15.8% and 2.6%. Masked hypertension was associated with age (odds ratio (OR) = 1.02, p = 0.012), high-normal office blood pressure (OR = 6.68, p<0.001), and obesity (OR = 3.63, p = 0.001). White-coat hypertension was significantly associated with age (OR = 1.07, p<0.001) but not with education, family history of hypertension, or physical activity.ConclusionsOur findings suggest that physicians should consider ambulatory blood pressure monitoring for older individuals with high-normal office blood pressure and/or who are obese.

Project description:Background: White coat hypertension (WCH) and masked hypertension (MH) can increase the risk of target organ damage. Home blood pressure monitoring is an important method for detecting WCH and MH. However, the prevalence and related factors of WCH and MH in China have been rarely reported. Objective: To explore the prevalence and related factors associated with white coat hypertension (WCH) and masked hypertension (MH) in Shunde District, Southern China. Methods: This study recruited subjects from the Physical Examination Center in Shunde Hospital, Southern Medical University. Office blood pressure and home blood pressure values were collected using the home blood pressure monitor with telemedicine device and office blood pressure monitor, and the prevalence of WCH and MH was calculated by the values. Multivariate logistic regression was used to explore the related factors for WCH and MH. Results: Four-hundred and sixty-one participants (61% male), with an average age of 49 years, were included. The prevalence of WCH and MH was 5.1 and 15.2%, respectively. Multivariate logistic regression analysis showed that smoking (OR = 4.71, 95% CI = 1.05–21.15) and family history of coronary heart disease (OR = 4.51, 95% CI = 1.08–18.93) were associated with higher odds of WCH. The associated factors for higher odds of MH were smoking (OR = 2.83, 95% CI = 1.11–7.23), family history of hypertension (OR = 2.17, 95% CI = 1.11–4.26) and family history of coronary heart disease (OR = 2.82, 95% CI = 1.07–7.45). Conclusion: WCH and MH are highly prevalent in the Physical Examination Center in Shunde Hospital, Southern Medical University. We found smoking and family history of coronary heart disease were related factors for WCH, and smoking, family history of hypertension and coronary heart disease were associated with the odds of MH. Home blood pressure monitoring with a telemedicine device should be recommended to identity abnormal BP phenotype.

Project description:Data on masked hypertension (MH) and white-coat hypertension (WCH) in African populations are needed to estimate the true prevalence of hypertension in these populations because they have the highest burden of the disease. We conducted the first systematic review and meta-analysis that summarized available data on the prevalence of WCH and MH in Africa. We searched PubMed and Scopus to identify all the articles published on MH and WCH in populations living in Africa from inception to November 30, 2017. We reviewed each study for methodological quality. A random-effects model was used to estimate the prevalence of WCH and MH across studies. Eleven studies were included, all having a low-risk of bias. The prevalence of masked hypertension was 11% (95% CI: 4.7-19.3; 10 studies) in a pooled sample of 7789 individuals. The prevalence of WCH was 14.8% (95% CI: 9.4-21.1; 8 studies) in a pooled sample of 4451 individuals. There was no difference on the prevalence of WCH and MH between studies in which participants were recruited from the community and the hospital. The prevalence of MH was higher in urban areas compared to rural ones; there was no difference for WCH. WHC and MH seem to be frequent in African populations, suggesting the importance of out-of-clinic BP measurement in the diagnosis and management of patients with hypertension in Africa, especially in urban areas for MH.

Project description:AimsThe 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 resultsData 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.ConclusionOur 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.

Project description:Our study evaluated whether there were differences in the prevalence of white-coat hypertension (WH) and masked hypertension (MH) based on the 2018 ESC/ESH and 2017 ACC/AHA hypertension guidelines in Korea. The motivation was the lowering of the diagnostic threshold for hypertension in the 2017 ACC/AHA guidelines. Of 319 participants without antihypertensive drug history and with suspected hypertension based on outpatient clinic blood pressure (BP) measured by physicians, 263 participants (51.6 ± 9.6 years; 125 men) who had valid research-grade office BP and 24-h ambulatory BP measurements were enrolled. WH prevalence based on daytime ambulatory BP among normotensive individuals was lower with the ESC/ESH guidelines than the ACC/AHA guidelines (29.0% vs. 71.4%, p < 0.001). However, MH prevalence based on daytime ambulatory BP among hypertensive individuals was higher based on the ESC/ESH guidelines (21.6% vs. 1.8%, p < 0.001). Seventy percent of WH cases (2017 ACC/AHA guidelines) and 95.2% of MH cases (2018 ESC/ESH guidelines) occurred in individuals with systolic BP of 130-139 mmHg and/or diastolic BP of 80-89 mmHg. The diagnostic threshold of the 2017 ACC/AHA guidelines yielded a higher prevalence of WH compared to that of the 2018 ESC/ESH guidelines. However, the prevalence of MH was higher with the 2018 ESC/ESH guidelines than with the 2017 ACC/AHA guidelines. The high prevalence of WH and MH in people with a systolic BP of 130-139 mmHg or diastolic BP of 80-89 mmHg suggests the need for a more active out-of-office BP measurement in this patient group.

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.

Project description: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:Arterial aging may link cardiovascular risk to white coat hypertension (WCH). The aims of the present study were to investigate the role of arterial aging in the white coat effect, defined as the difference between office and 24-hour ambulatory systolic blood pressures, and to compare WCH with prehypertension (PH) with respect to target organ damage and long-term cardiovascular mortality. A total of 1257 never-been-treated volunteer subjects from a community-based survey were studied. WCH and PH were defined by office and 24-hour ambulatory blood pressures. Left ventricular mass index, carotid intima-media thickness, estimated glomerular filtration rate, carotid-femoral pulse wave velocity, carotid augmentation index, amplitude of the reflection pressure wave, and 15-year cardiovascular mortality were determined. Subjects with WCH were significantly older and had greater body mass index, blood pressure values, intima-media thickness, carotid-femoral pulse wave velocity, augmentation index, amplitude of the backward pressure wave, and a lower estimated glomerular filtration rate than PH. Amplitude of the backward pressure wave was the most important independent correlate of the white coat effect in multivariate analysis (model r(2)=0.451; partial r(2)/model r(2)=90.5%). WCH had significantly greater cardiovascular mortality than PH (hazard ratio, 2.94; 95% confidence interval, 1.09-7.91), after accounting for age, sex, body mass index, smoking, fasting plasma glucose, and total cholesterol/high-density lipoprotein-cholesterol ratio. Further adjustment of the model for amplitude of the backward pressure wave eliminated the statistical significance of the WCH effect. In conclusion, the white coat effect is mainly caused by arterial aging. WCH carries higher risk for cardiovascular mortality than PH, probably via enhanced wave reflections that accompany arterial aging.

Project description:Guidelines recommend using out-of-office blood pressure (BP) measurements to confirm the diagnoses of hypertension and in the titration of antihypertensive medication. The prevalence of out-of-office BP phenotypes for an office systolic/diastolic BP goal <140/90 mm Hg has been reported. However, the prevalence of these phenotypes when targeting an office systolic/diastolic BP goal <120/80 is unknown. The SPRINT (Systolic Blood Pressure Intervention Trial) Ambulatory BP Ancillary study evaluated out-of-office BP using ambulatory BP monitoring in 897 participants 27 months after randomization to intensive versus standard BP targets (office systolic BP <120 versus <140 mm Hg). We used office and daytime BP to assess the proportion of participants with white-coat effect (standard target: office BP ≥140/90 mm Hg and daytime BP <135/85 mm Hg versus intensive target: office BP ≥120/80 mm Hg and daytime BP <120/80 mm Hg) and masked uncontrolled hypertension (standard target: office BP <140/90 mm Hg and daytime BP ≥135/85 mm Hg versus intensive target: office BP <120/80 mm Hg and daytime BP ≥120/80 mm Hg) in each treatment arm. The prevalence of white-coat effect and masked uncontrolled hypertension was 9% and 34%, in both treatment groups. Among participants with uncontrolled office BP, white-coat effect was present in 20% and 23% in the intensive and standard groups, respectively. Among participants with controlled office BP, masked uncontrolled hypertension was present in 62% and 56% in the intensive and standard groups, respectively. In conclusion, a more intensive BP target resulted in a similar proportion of patients with white-coat effect and masked uncontrolled hypertension compared with a standard target.

Project description:Masked hypertension (MHT), defined as normal office blood pressure (BP) but high ambulatory BP, has been associated with increased cardiovascular risk. Although MHT has been associated with obesity, there is limited knowledge on the prevalence and covariates of MHT in obese cohorts.Office and ambulatory BP recordings and other cardiovascular risk factors were assessed in 323 obese participants included in the fat-associated cardiovascular dysfunction study (mean age 48.9±9.0 years, 55% women, mean BMI 32.3±4.4?kg/m). Office BP 130-139/85-89?mmHg was considered high-normal. Subclinical arterial damage was identified as carotid-femoral pulse wave velocity more than 10?m/s by applanation tonometry or carotid plaque by ultrasound (maximal intima-media thickness ?1.5?mm).MHT was present in 17.1% of the population. Patients with MHT had a higher prevalence of metabolic syndrome, high-normal office BP, and were more often male compared with the normotensive (NT) individuals (all P<0.05), but were younger and had lower prevalence of diabetes and subclinical arterial damage than the sustained hypertensive group (all P<0.05). In multinomial logistic regression analysis, MHT was associated with the presence of metabolic syndrome and high-normal office BP compared with NT individuals, and lower pulse wave velocity and fewer carotid plaques than sustained hypertension (all P<0.05).In obese patients, MHT was associated with the presence of metabolic syndrome and high-normal office BP compared with NT individuals, but less subclinical arterial damage than sustained hypertensive patients.
