Abstract
BACKGROUND Accurate quantification of sodium intake based on self-reported dietary assessments has been a persistent challenge. We aimed to apply machine-learning (ML) algorithms to predict 24-hour urinary sodium excretion from self-reported questionnaire information. METHODS AND RESULTS We analyzed 3454 participants from the NHS (Nurses' Health Study), NHS-II (Nurses' Health Study II), and HPFS (Health Professionals Follow-Up Study), with repeated measures of 24-hour urinary sodium excretion over 1 year. We used an ensemble approach to predict averaged 24-hour urinary sodium excretion using 36 characteristics. The TOHP-I (Trial of Hypertension Prevention I) was used for the external validation. The final ML algorithms were applied to 167 920 nonhypertensive adults with 30-year follow-up to estimate confounder-adjusted hazard ratio (HR) of incident hypertension for predicted sodium. Averaged 24-hour urinary sodium excretion was better predicted and calibrated with ML compared with the food frequency questionnaire (Spearman correlation coefficient, 0.51 [95% CI, 0.49-0.54] with ML; 0.19 [95% CI, 0.16-0.23] with the food frequency questionnaire; 0.46 [95% CI, 0.42-0.50] in the TOHP-I). However, the prediction heavily depended on body size, and the prediction of energy-adjusted 24-hour sodium excretion was modestly better using ML. ML-predicted sodium was modestly more strongly associated than food frequency questionnaire-based sodium in the NHS-II (HR comparing Q5 versus Q1, 1.48 [95% CI, 1.40-1.56] with ML; 1.04 [95% CI, 0.99-1.08] with the food frequency questionnaire), but no material differences were observed in the NHS or HPFS. CONCLUSIONS The present ML algorithm improved prediction of participants' absolute 24-hour urinary sodium excretion. The present algorithms may be a generalizable approach for predicting absolute sodium intake but do not substantially reduce the bias stemming from measurement error in disease associations.

Am J Hypertens 2024; 37:421-428. [PMID: 38483188 DOI: 10.1093/ajh/hpae031] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2023] [Revised: 01/17/2024] [Accepted: 03/10/2024] [Indexed: 05/16/2024] Open
Abstract
BACKGROUND Self-measured blood pressure monitoring (SMBP) is an important out-of-office resource that is effective in improving hypertension control. Changes in SMBP use during the Coronavirus Disease 2019 (COVID-19) pandemic have not been described previously. METHODS Behavioral Risk Factor Surveillance System (BRFSS) data were used to quantify changes in SMBP use between 2019 (prior COVID-19 pandemic) and 2021 (during the COVID-19 pandemic). Fourteen states administered the SMBP module in both years. All data were self-reported from adults who participated in the BRFSS survey. We assessed the receipt of SMBP recommendations from healthcare professionals and actual use of SMBP among those with hypertension (n = 68,820). Among those who used SMBP, we assessed SMBP use at home and sharing BP readings electronically with healthcare professionals. RESULTS Among adults with hypertension, there was no significant changes between 2019 and 2021 in those reporting SMBP use (57.0% vs. 55.7%) or receiving recommendations from healthcare professionals to use SMBP (66.4% vs. 66.8%). However, among those who used SMBP, there were significant increases in use at home (87.7% vs. 93.5%) and sharing BP readings electronically (8.6% vs. 13.1%) from 2019 to 2021. Differences were noted by demographic characteristics and residence state. CONCLUSIONS Receiving a recommendation from the healthcare provider to use SMBP and actual use did not differ before and during the COVID-19 pandemic. However, among those who used SMBP, home use and sharing BP readings electronically with healthcare professional increased significantly, although overall sharing remained low (13.1%). Maximizing advances in virtual connections between clinical and community settings should be leveraged for improved hypertension management.

Abstract
BACKGROUND The rehospitalization rate in a hypertensive emergency is high, indicating the necessity for optimizing its long-term management. The role of the renin-angiotensin system (RAS) blockade in this disorder remains uncertain. METHODS We conducted a retrospective analysis involving 20 admitted patients who received aliskiren, a direct renin inhibitor (DRI), for the management of hypertensive emergency associated with elevated plasma renin activity (PRA). We analyzed the changes in blood pressure (BP), kidney function, and RAS activity in the subacute and chronic phases. RESULTS The use of DRI was associated with a marked reduction in PRA (median, from 25.0 to 1.2 ng/ml/h) and serum aldosterone levels (from 404 to 130 pg/ml) during the index admission. BP also decreased from 226/143 to 142/80 mm Hg. A comparison of clinical characteristics according to the renal function indicated that dialysis-dependent patients had higher aldosterone levels than non-dialysis-dependent patients at admission, despite comparable BP levels. After a median follow-up of 567 days in non-dialysis-dependent patients with DRI, eGFR levels were significantly increased from 14.3 to 23.1 ml/min/1.73 m2. PRA levels were consistently suppressed at 0.8 ng/ml/h. We found a significant correlation between the degree of PRA suppression and changes in eGFR (r = -0.58), indicating that the effective blockade of RAS is associated with the preservation of eGFR in the study subjects. CONCLUSIONS DRI can successfully suppress PRA in patients with high-renin hypertensive emergency in both subacute and chronic phases. An efficient RAS blockade is associated with preserved renal function in these patients.

A potential pathway for identifying hypertension among urban residents aged 60+ years in China: the role of health insurance. Front Public Health 2024; 12:1420465. [PMID: 38813412 PMCID: PMC11133590 DOI: 10.3389/fpubh.2024.1420465] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2024] [Accepted: 05/06/2024] [Indexed: 05/31/2024] Open
Abstract
Background Identification is the first step for treatment of hypertension. However, the awareness rate of hypertension was not high globally. This study aimed to examine the potential role of health insurance for early-identifying hypertension among urban older residents in China. Methods In this cross-sectional study, urban residents aged 60+ years were chosen from Nanjing municipality of China in 2018. The outcome measure was hypertension status ("no hypertension," "diagnosed hypertension" or "un-diagnosed hypertension"). Independent variable was health insurance ("Urban Employee Basic Medical Insurance scheme, UEBMI" or "Urban Resident Basic Medical Insurance scheme, URBMI"). Logistic regression models were introduced to estimate odds ratio (OR) and 95% confidence interval (CI) to examine the association between health insurance and hypertension. Results Totally, 19,742 participants completed the study. Among overall, URBMI and UEBMI participants, 47.2% (95%CI = 46.5, 47.9%), 38.4% (95%CI = 37.3, 39.6%) and 52.1% (95%CI = 51.2, 53.0%), separately, were diagnosed with hypertension, while the prevalence of un-diagnosed hypertension was 12.7% (95%CI = 12.2, 13.2%), 18.5% (95%CI = 17.6, 19.4%) and 9.6% (95%CI = 9.1, 10.1%), respectively. For overall participants, those with UEBMI were more likely to have hypertension identified (OR = 1.20; 95%CI = 1.11, 1.29) and at lower odds to experience un-diagnosed hypertension (OR = 0.68; 95%CI = 0.61, 0.76) compared to their counterparts with URBMI after control for potential confounders. Moreover, such associations of health insurance with diagnosed and un-diagnosed hypertension were also observed among participants stratified by age and gender. Conclusion Favorable health insurance may be a pathway for identifying hypertension among urban older residents in China. This study has important public health implications that hypertension may be identified early through favorable health insurance policies for older residents in China.

Cardio-Ankle Vascular Index as a Marker of Left Ventricular Hypertrophy in Treated Hypertensives: Findings From the Pamela Study. Am J Hypertens 2024; 37:399-406. [PMID: 38441300 DOI: 10.1093/ajh/hpae022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2024] [Revised: 02/28/2024] [Accepted: 02/29/2024] [Indexed: 05/16/2024] Open
Abstract
BACKGROUND Findings regarding the association between Cardio-Ankle Vascular Index (CAVI) and cardiac hypertension-mediated organ damage (HMOD), such as left ventricular hypertrophy (LVH) assessed by echocardiography, in elderly hypertensive patients are scanty. We sought to investigate this issue in the hypertensive fraction of the general population treated with anti-hypertensive drugs enrolled in the Pressioni Monitorate E Loro Associazioni (PAMELA) study. METHODS The study included 239 out of 562 participants who attended the second and third surveys of the PAMELA study performed after 10 and 25 years from the initial evaluation. Data collection included medical history, anthropometric parameters, office, home, ambulatory blood pressure (BP), blood examinations, echocardiography, and CAVI measurements. RESULTS In the whole study sample (age 69 ± 9 years, 54% males), CAVI was positively correlated with age, office, home, ambulatory systolic BP, LV mass (LVM) index, and negatively associated with body mass index (BMI). In multivariate analysis, CAVI was associated with the LVM index (P < 0.05) independently of major confounders. The participants with LVH exhibited significantly higher CAVI (10.6 ± 2.8 vs. 9.2 ± 1.8 m/s P < 0.001), larger left atrial diameter, and lower LV ejection fraction values than their counterparts without it. The CAVI value of 9.4 m/s was the best cut-off for prediction of LVH in the whole sample. CONCLUSIONS Our study provides new evidence of an independent association between CAVI and LVH in treated elderly hypertensive patients and suggests that the use of this metric of arterial stiffness could not only be used to evaluate vascular damage but also to stratify the risk of LVH.

Abstract
BACKGROUND Chronic kidney disease (CKD) is a common comorbidity in patients with apparent treatment-resistant hypertension (aTRH). We assessed clinical outcomes, healthcare resource utilization events, and costs in patients with aTRH or difficult-to-control hypertension and stage 3-4 CKD with uncontrolled vs. controlled BP. METHODS This retrospective cohort study used linked IQVIA Ambulatory EMR-US and IQVIA PharMetrics Plus claims databases. Adult patients had claims for ≥3 antihypertensive medication classes within 30 days between 01/01/2015 and 06/30/2021, 2 office BP measures recorded 1-90 days apart, ≥1 claim with ICD-9/10-CM diagnosis codes for CKD 3/4, and ≥1 year of continuous enrollment. Baseline BP was defined as uncontrolled (≥130/80 mm Hg) or controlled (<130/80 mm Hg) BP. Outcomes included risk of major adverse cardiovascular events plus (MACE+; stroke, myocardial infarction, heart failure hospitalization), end-stage renal disease (ESRD), healthcare resource utilization events, and costs during follow-up. RESULTS Of 3,966 patients with stage 3-4 CKD using ≥3 antihypertensive medications, 2,479 had uncontrolled BP and 1,487 had controlled BP. After adjusting for baseline differences, patients with uncontrolled vs. controlled BP had a higher risk of MACE+ (HR [95% CI]: 1.18 [1.03-1.36]), ESRD (1.85 [1.44-2.39]), inpatient hospitalization (rate ratio [95% CI]: 1.35 [1.28-1.43]), and outpatient visits (1.12 [1.11-1.12]) and incurred higher total medical and pharmacy costs (mean difference [95% CI]: $10,055 [$6,741-$13,646] per patient per year). CONCLUSIONS Patients with aTRH and stage 3-4 CKD and uncontrolled BP despite treatment with ≥3 antihypertensive classes had an increased risk of MACE+ and ESRD and incurred greater healthcare resource utilization and medical expenditures compared with patients taking ≥3 antihypertensive classes with controlled BP.

Differences in knowledge, attitude, and practice regarding hypertension by access to a community-based screening program (POSBINDU): A cross-sectional study from four districts in Indonesia. PLoS One 2024; 19:e0303503.

Abstract
BACKGROUND A high prevalence of hypertension is found in Low- and Middle-income Countries (LMICs) including in Indonesia. However, hypertension awareness, treatment, and control are relativity poor. A community-based program to screen and educate people on non-communicable disease prevention (POSBINDU) was launched by the Indonesian government. However, the association between participation in the POSBINDU program with increasing knowledge, attitude, and practice of hypertension has not been widely assessed. In this study, we compared the knowledge, attitudes, and practices among people who accessed the POSBINDU and those who did not access the POSBINDU program. Subsequently, factors associated with the knowledge, attitudes, and practices among people who accessed the POSBINDU and those who did not access the POSBINDU were explored. METHODS This was an observational study with a cross-sectional design measuring the knowledge, attitudes, and practices for hypertension control in four districts in Indonesia from October 2019 to January 2020. A total of 1,988 respondents were included in this study. A questionnaire was used to assess the knowledge, attitudes, and practices of hypertension. Simple logistic regression was used to investigate the correlation between the characteristics of respondents and knowledge, attitudes, and practice status. Multiple logistic regression tests were conducted to investigate factors associated with knowledge, attitudes, and practice status. RESULTS We found that people who accessed POSBINDU had higher odds of having better knowledge (aOR:1.4; 95%CI:1.2-1.8), however, accessed to POSBINDU was associated with lower attitudes (aOR:0.6; 85%CI: 0.5-0.7) and had no association with hypertension-related practice. CONCLUSION People who accessed POSBINDU have an association with good knowledge, but the association with good attitude and practice was less clear. Therefore, an improvement in the POSBINDU program is needed to increase the attitudes and practices of hypertension.

Abstract
BACKGROUND The relationship between systolic blood pressure (SBP) and longevity is not fully understood. We aimed to determine which SBP levels in women ≥65 years of age with or without blood pressure medication were associated with the highest probability of surviving to 90 years of age. METHODS The study population consisted of 16 570 participants enrolled in the Women's Health Initiative who were eligible to survive to 90 years of age by February 28, 2020, without a history of cardiovascular disease, diabetes, or cancer. Blood pressure was measured at baseline (1993 through 1998) and then annually through 2005. The outcome was defined as survival to 90 years of age with follow-up. Absolute probabilities of surviving to 90 years of age were estimated for all combinations of SBP and age using generalized additive logistic regression modeling. The SBP that maximized survival was estimated for each age, and a 95% CI was generated. RESULTS During a median follow-up of 19.8 years, 9723 of 16 570 women (59%) survived to 90 years of age. Women with an SBP between 110 and 130 mm Hg at attained ages of 65, 70, 75, and 80 years had a 38% (95% CI, 34%-48%), 54% (52%-56%), 66% (64%-67%), or 75% (73%-78%) absolute probability to survive to 90 years of age, respectively. The probability of surviving to 90 years of age was lower for greater SBP levels. Women at the attained age of 80 years with 0%, 20%, 40%, 60%, 80%, or 100% time in therapeutic range (defined as an SBP between 110 and 130 mm Hg) had a 66% (64%-69%), 68% (67%-70%), 71% (69%-72%), 73% (71%-74%), 75% (72%-77%), or 77% (74%-79%) absolute survival probability to 90 years of age. CONCLUSIONS For women >65 years of age with low cardiovascular disease and other chronic disease risk, an SBP level <130 mm Hg was found to be associated with longevity. These findings reinforce current guidelines targeting an SBP target <130 mm Hg in older women.

Abstract
BACKGROUND There is a broad pulse pressure (PP) and a high prevalence of carotid plaques in old adults. Previous studies have indicated that PP is strongly associated with carotid plaque formation. This study aimed to explore this association in old adults with uncontrolled hypertension. METHODS 1371 hypertensive patients aged ≥ 60 years with uncontrolled hypertension were enrolled in a community-based screening in Hangzhou, China. Carotid plaques were assessed using ultrasonography. Logistic regression models were used to estimate the association between PP and carotid plaques by odds ratios (ORs) and 95% confidence intervals (CIs). RESULTS Carotid plaques were detected in 639 (46.6%) of subjects. Multiple plaques were found in 408 (63.8%) and soft plaques in 218 (34.1%). Elevated PP was associated with a high prevalence of carotid plaques. After adjusting for traditional risk factors, compared to patients within the lowest tertile of PP, those within the highest tertiles had an increased risk of carotid plaques (OR 2.061, CI 1.547-2.745). For each 1-SD increase, the risk increased by 40.1% (OR 1.401, CI 1.237-1.587). There was a nonlinear association between PP and carotid plaques (P nonlinearity = 0.039). The risk increased rapidly after the predicted PP level reached around 60 mmHg. The associations were stronger among participants with multiple and soft plaques. CONCLUSIONS Our findings suggested that PP was independently associated with carotid plaques in old adults with uncontrolled hypertension who have an increased risk of atherosclerosis.

Abstract
BACKGROUND AND AIM The impact of trace elements and heavy metals on human health has attracted widespread attention. However, the correlation between urinary chromium concentrations and blood pressure remains unclear and inadequately reported, and the aim of this study was to investigate the relationship between urinary chromium concentrations and blood pressure in adults in the United States (US). METHODS We utilized data from the National Health and Nutrition Examination Survey (NHANES) 2017-2018 for this study. Multivariate logistic regression and multivariate linear regression were used to explore the association of urinary chromium concentrations with hypertension and blood pressure. Additionally, we also performed subgroup analysis and restricted cubic splines (RCS). RESULTS A total of 2958 participants were enrolled in this study. The overall mean systolic blood pressure and diastolic blood pressure were 123.98 ± 0.60, 72.66 ± 0.57 mmHg, respectively. The prevalence of hypertension was found in 41.31% of the whole participants. In the fully adjusted model, we did not observe a correlation between urinary chromium concentrations and the risk of hypertension and systolic blood pressure. However, we found a negative association between urinary chromium concentrations and diastolic blood pressure. In subgroup analysis, we observed a positive association between urinary chromium and the risk of hypertension among participants older than 60 years of age and those who were Non-Hispanic Black. The interaction term highlighted the influence of age and race on this positive association. We also found a negative association of urinary chromium with diastolic blood pressure in male, participants who were current smokers, overweight, and other races, as well as those without alcohol use and anti-hypertensive drug use. However, the interaction term only revealed the influence of alcohol consumption on the negative association. CONCLUSION Our study suggested that urinary chromium concentrations may show a negative association with diastolic blood pressure and this association was significantly dependent on alcohol consumption. Besides, a positive association between urinary chromium and the risk of hypertension was also found among participants older than 60 years of age and those who were Non-Hispanic Black.

Abstract
BACKGROUND Studies have shown that RASGRP1 was potently associated with the onset of type 2 diabetes mellitus (T2DM), and RASGRP1 rs7403531 was significantly correlated with islet function in T2DM patients. However, the effect of RASGRP1 polymorphism on blood glucose and blood pressure in T2DM patients after continuous treatment has yet to be fully elucidated. OBJECTIVE This study aimed to explore the association between RASGRP1 genetic polymorphism and cardiovascular complications in T2DM patients, so as to provide more evidence for the individualized treatment of T2DM patients. METHODS We retrospectively analyzed a large-scale multicenter drug clinical study cohort that based on a 2 × 2 factorial (glucose control axis and blood pressure lowering axis) randomized controlled design, with follow-up for 5 years. The major vascular endpoint events included cardiovascular death, non-fatal stroke, coronary heart disease, new-onset or worsening renal disease, and diabetic retinopathy. RASGRP1 rs12593201, rs56254815 and rs7403531 were finally selected as candidate single nucleotide polymorphisms. Mixed linear model and Cox hazard ratio (HR) model were used for data analysis with IBM SPSS (version 20.0 for windows; Chicago, IL). RESULTS Our study enrolled 1357 patients with high-risk diabetes, with a mean follow-up duration of 4.8 years. RASGRP1 rs7403531 was associated with vascular events in hypoglycemic and antihypertensive therapy. Specifically, compared with CC carriers, patients with CT/TT genotype had fewer major microvascular events (HR = 0.41, 95% confidence interval (CI) 0.21-0.80, P = 0.009), and reduced the risk of major eye disease events (HR = 0.44, 95% CI 0.20-0.94, P = 0.03). For glucose lowering axis, CT/TT carriers had a lower risk of secondary nephropathy (HR = 0.48, 95% CI 0.25-0.92, P = 0.03) in patients with standard glycemic control. For blood pressure lowering axis, all cerebrovascular events (HR = 2.24, 95% CI 1.11-4.51, P = 0.025) and stroke events (HR = 2.07, 95% CI 1.03-4.15, P = 0.04) were increased in patients with CC genotype compared to those with CT/TT genotype in the placebo group, respectively. Furthermore, patients with CC genotype showed a reduced risk of major cerebrovascular events in antihypertensive group (HR = 0.36, 95% CI 0.15-0.86, P = 0.021). For RASGRP1 rs56254815, compared with the AA genotype carriers, the systolic blood pressure of AG/GG carriers in the antihypertensive group decreased by 1.5mmhg on average (P = 0.04). In the placebo group, the blood pressure of AG/GG carriers was 1.7mmHg higher than that of AA carriers (P = 0.02). CONCLUSION We found that patients with G allele of RASGRP1 (rs56254815) showed a better antihypertensive therapy efficacy in T2DM patients. The rs7403531 T allele could reduce the risk of major microvascular events and major eye diseases in T2DM patients receiving either hypoglycemic or antihypertensive therapy. Our findings suggest that RASGRP1 genetic polymorphism might predict the cardiovascular complications in T2DM patients.

Hypertension Trends and Disparities Over 12 Years in a Large Health System: Leveraging the Electronic Health Records. J Am Heart Assoc 2024; 13:e033253. [PMID: 38686864 DOI: 10.1161/jaha.123.033253] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/23/2023] [Accepted: 03/29/2024] [Indexed: 05/02/2024]
Abstract
BACKGROUND The digital transformation of medical data enables health systems to leverage real-world data from electronic health records to gain actionable insights for improving hypertension care. METHODS AND RESULTS We performed a serial cross-sectional analysis of outpatients of a large regional health system from 2010 to 2021. Hypertension was defined by systolic blood pressure ≥140 mm Hg, diastolic blood pressure ≥90 mm Hg, or recorded treatment with antihypertension medications. We evaluated 4 methods of using blood pressure measurements in the electronic health record to define hypertension. The primary outcomes were age-adjusted prevalence rates and age-adjusted control rates. Hypertension prevalence varied depending on the definition used, ranging from 36.5% to 50.9% initially and increasing over time by ≈5%, regardless of the definition used. Control rates ranged from 61.2% to 71.3% initially, increased during 2018 to 2019, and decreased during 2020 to 2021. The proportion of patients with a hypertension diagnosis ranged from 45.5% to 60.2% initially and improved during the study period. Non-Hispanic Black patients represented 25% of our regional population and consistently had higher prevalence rates, higher mean systolic and diastolic blood pressure, and lower control rates compared with other racial and ethnic groups. CONCLUSIONS In a large regional health system, we leveraged the electronic health record to provide real-world insights. The findings largely reflected national trends but showed distinctive regional demographics and findings, with prevalence increasing, one-quarter of the patients not controlled, and marked disparities. This approach could be emulated by regional health systems seeking to improve hypertension care.

Abstract
BACKGROUND Hypertension is a stroke risk factor with known disparities in prevalence and management between Black and White patients. We sought to identify if racial differences in presenting blood pressure (BP) during acute ischemic stroke exist. METHODS AND RESULTS Adults with acute ischemic stroke presenting to an emergency department within 24 hours of last known normal during study epochs 2005, 2010, and 2015 within the Greater Cincinnati/Northern Kentucky Stroke Study were included. Demographics, histories, arrival BP, National Institutes of Health Stroke Scale score, and time from last known normal were collected. Multivariable linear regression was used to determine differences in mean BP between Black and White patients, adjusting for age, sex, National Institutes of Health Stroke Scale score, history of hypertension, hyperlipidemia, smoking, stroke, body mass index, and study epoch. Of 4048 patients, 853 Black and 3195 White patients were included. In adjusted analysis, Black patients had higher presenting systolic BP (161 mm Hg [95% CI, 159-164] versus 158 mm Hg [95% CI, 157-159], P<0.01), diastolic BP (86 mm Hg [95% CI, 85-88] versus 83 mm Hg [95% CI, 82-84], P<0.01), and mean arterial pressure (111 mm Hg [95% CI, 110-113] versus 108 mm Hg [95% CI, 107-109], P<0.01) compared with White patients. In adjusted subanalysis of patients <4.5 hours from last known normal, diastolic BP (88 mm Hg [95% CI, 86-90] versus 83 mm Hg [95% CI, 82-84], P<0.01) and mean arterial pressure (112 mm Hg [95% CI, 110-114] versus 108 mm Hg [95% CI, 107-109], P<0.01) were also higher in Black patients. CONCLUSIONS This population-based study suggests differences in presenting BP between Black and White patients during acute ischemic stroke. Further study is needed to determine whether these differences influence clinical decision-making, outcome, or clinical trial eligibility.

Abstract
BACKGROUND Coronavirus disease 2019 (COVID-19) has various sequelae, one of which might be hypertension. We aimed to evaluate COVID-19's impact on blood pressure (BP) in non-hospitalized patients at one-year follow-up. METHOD A total of 7,950 consecutive COVID-19 patients regularly visiting our cardiology clinic were retrospectively screened. Patients' electronic medical records including demographics, comorbidities, vital signs, treatments, and outcomes, were reviewed by two physicians. Individuals with at least one BP measurement in the three months preceding COVID-19 and one measurement in 12 months or more following recovery were included. BP levels before and after COVID-19 were compared using the paired t-test. RESULTS 5,355 confirmed COVID-19 patients (mean age 55.51 ± 15.38 years) were included. Hypertension (56.9%) and diabetes mellitus (34%) were the predominant comorbidities, and 44.3% had prior major adverse cardiovascular events. Both systolic (126.90 ± 20.91 vs. 139.99 ± 23.94 mmHg, P < 0.001) and diastolic BP (80.54 ± 13.94 vs. 86.49 ± 14.40 mmHg, P < 0.001) were significantly higher post-COVID-19 vs. pre-COVID-19. Notably, 456 (14%) hypertensive patients experienced exacerbated hypertension, while 408 (17%) patients developed new-onset hypertension, overall 864 (16%) of patients had exacerbation or new hypertension. Linear regression analysis revealed that advanced age, smoking, previous cardiovascular events, hypertension, and diabetes mellitus predict increased BP following COVID-19 (P < 0.001). CONCLUSION COVID-19 raised systolic and diastolic BP in the long term in non-hospitalized patients, with over one-sixth developing new-onset or exacerbated hypertension. All patients should be evaluated regarding BP, following COVID-19 recovery, particularly those with the mentioned predictive factors. (clinicaltrial.gov: NCT05798208).

Abstract
BACKGROUND Secondary hypertension (SH) is a form of high blood pressure caused by an identifiable underlying condition. Although, it accounts for a small fraction of the overall hypertensive population, detection and management of SH is of utmost importance, because SH phenotypes carry a high cardiovascular risk and can possibly be cured by timely treatment. CONTENT This review focuses on the endocrine causes of SH, such as primary aldosteronism, Cushing syndrome, thyroid disease, pheochromocytoma and paraganglioma, acromegaly, and rare monogenic forms. It discusses current biomarkers, analytical methods, and diagnostic strategies, highlighting advantages and limitations of each approach. It also explores the emerging -omics technologies that can provide a comprehensive and multidimensional assessment of SH and its underlying mechanisms. SUMMARY Endocrine SH is a heterogeneous and complex condition that requires proper screening and confirmatory tests to avoid diagnostic delays and improve patient outcomes. Careful biomarker interpretation is essential due to potential interferences, variability, and method-dependent differences. Liquid chromatography-tandem mass spectrometry is a superior method for measuring low-concentration hormones and metabolites involved in SH, but it requires expertise. Omics approaches have great potential to identify novel biomarkers, pathways, and targets for SH diagnosis and treatment, especially considering its multifactorial nature.

J Hum Hypertens 2024; 38:444-451. [PMID: 38570625 PMCID: PMC11076206 DOI: 10.1038/s41371-024-00909-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2023] [Revised: 03/19/2024] [Accepted: 03/25/2024] [Indexed: 04/05/2024]
Abstract
Non-dipping blood pressure (BP) pattern is a predictor for cardiovascular (CV) events and mortality. We evaluated dipping status change and its association with incidence of non-fatal CV events in middle-aged subjects. The OPERA study was carried out during the years 1991-1993, with a follow-up study 21.7 years later. In this study, we included 452 participants with 24-h ambulatory BP measurements (ABPM) available in both surveys. The study population was divided into four groups according to the dipping pattern change: dipping-dipping (n = 152/33.6%), dipping-non-dipping (n = 198/43.8%), non-dipping-dipping (n = 20/4.4%), and non-dipping-non-dipping (n = 82/18.1%). Sixty-five participants experienced a CV event (14.4%) during the 21.7 (SD 0.8) years of follow-up. The incidence of events was highest (28%) in the non-dipping-non-dipping group, and lowest (6.6%) in the dipping-dipping group (p < 0.001). In Cox regression analyses the covariates were age, sex, total cholesterol, hypertension and use of antihypertensive medication, systolic office BP and ambulatory mean or nighttime systolic BP, as well as the change in the variables during the follow-up period. After adjustments, the association of the non-dipping-non-dipping pattern with CV events compared with the dipping-dipping pattern remained significant (HR 4.01; 95% CI 1.89-8.67, p < 0.001). In summary, non-dipping-non-dipping pattern was associated with non-fatal CV events in the long term, and the effect was independent of the conventional risk factors including office and ambulatory BP levels.

Abstract
The association between uric acid (UA) and hyperuricemia with 5-year hypertension incidence using different blood pressure (BP) diagnostic references in men and women without cardiometabolic diseases is unknown. We used the checkup data from Kagoshima Kouseiren Hospital. All participants with hypertension or on BP medication, diabetes, dyslipidemia, obesity, estimated glomerular filtration rate<60 ml/min/1.73m2, metabolic syndrome, history of gout, and UA-lowering medication were excluded. UA was categorized into sex-specific quartiles and hyperuricemia was defined as UA > 7 mg/dl in men and UA > 6 mg/dl in women. We performed multivariate logistic regression to assess the effects of UA on hypertension development. The 5-year hypertension incidence was defined as subsets of BP ≥ 140/90 mmHg in cohort 1 and BP ≥ 130/80 mmHg in cohort 2. The study enrolled 21,443 participants (39.8%, men) in cohort 1 and 15,245 participants (36.5%, men) in cohort 2. The incidence of hypertension in cohorts 1 and 2 over 5 years was 16.3% and 29.7% in men and 10.9% and 21.4% in women, respectively. When comparing the fourth to the first UA quartile, there was an association with hypertension in men in cohort 1, with odds ratio (OR): 1.36 (95% confidence interval [CI], 1.13-1.63, p < 0.01) and cohort 2, OR: 1.31 (95%CI, 1.09-1.57, p < 0.01), respectively, but not in women. Additionally, an association between hyperuricemia and hypertension was observed in men only in cohort 1, with OR: 1.23 (95%CI, 1.07-1.42, p = 0.02), and in women in cohort 2, OR: 1.57 (95%CI, 1.14-2.16, p < 0.01). The effect of UA on the development of hypertension is influenced by sex and incidence differs with the BP reference used. Uric acid effect on the development of hypertension is affected by sex and incidence differs with the BP reference used.

Abstract
This study illustrated the effectiveness of the knowledge, attitude, practice (KAP) intervention model for community hypertension in the elderly by the community physician-led, describing the study design and baseline data. The aim of the study was to compare the changes in the elderly hypertensive population before and after the KAP intervention model by managing the elderly hypertensive patients for a period of 1 year. Basic information and risk factors affecting blood pressure control based on baseline data of recruited elderly hypertensive patients. The management approach consists of two parts: (1) the unified management of the community physician to whom the patient belongs; and (2) the management of the contracted patient by the community physician. The aim was to demonstrate the anti-hypertensive effectiveness (control rate, blood pressure reduction, and pulse pressure), the distribution of blood pressure types, and the change of the KAP in elderly hypertensive patients before and after the intervention. The KAP intervention model was administered to 2660 elderly hypertensive patients in a 1-year period. The blood pressure control rate improved by 54.03%. Mean values of overall systolic and diastolic blood pressure decreased by 16.00 and 5.31 mmHg, respectively. The proportion of isolated systolic hypertension (ISH) and systolic-diastolic hypertension (SDH) decreased by 29.14% and 24.81%, respectively. The KAP compliance improved significantly. These results suggest that the community physician-led KAP intervention model is effective in the management of hypertension in the elderly.

Abstract
BACKGROUND Fewer than one-half of U.S. adults with hypertension (HTN) have it controlled and one-third are unaware of their condition. The emergency department (ED) represents a setting to improve HTN control by increasing awareness of asymptomatic hypertension (aHTN) according to the 2013 American College of Emergency Physicians asymptomatic elevated blood pressure clinical policy. OBJECTIVE The aim of the study was to estimate the prevalence and management of aHTN in U.S. EDs. METHODS We examined the 2016-2019 National Hospital Ambulatory Medical Care Surveys to provide a more valid estimate of aHTN visits in U.S. EDs. aHTN is defined as adult patients with blood pressure ≥ 160/100 mm Hg at triage and discharge without trauma or signs of end organ damage. We then stratified aHTN into a 160-179/100-109 mm Hg subgroup and > 180/110 mm Hg subgroup and examined diagnosis and treatment outcomes. RESULTS Approximately 5.9% of total visits between 2016 and 2019 met the definition for aHTN and 74% of patients were discharged home, representing an estimated 26.5 million visits. Among those discharged home, emergency physicians diagnosed 13% (95% CI 10.6-15.8%) and treated aHTN in 3.9% (95% CI 2.8-5.5%) of patients in the higher aHTN subgroup. In the lower aHTN subgroup, diagnosis and treatment decreased to 3.1% (95% CI 2.4-4.1%) and 1.2% (95% CI 0.7-2.0%), respectively. CONCLUSIONS Millions of ED patients found to have aHTN are discharged home without diagnosis or treatment. Although management practices follow clinical policy to delay treatment of aHTN, there are missed opportunities to diagnosis aHTN.

Abstract
Broad evidence indicates that hypertensive response to exercise (HRE) is associated with future hypertension (aHT) at rest and cardiovascular morbidity and mortality. Nevertheless, a consensus on the definition of HRE is lacking and the comparability of the available data is difficult due to a wide variation of definitions used. This review aims to harmonize currently available definitions of HRE in normotensive and athletic populations and to propose a generally valid cut-off applicable in everyday clinical practice. A literature search on PubMed and Embase was conducted to assemble and analyze the most recent data. Various definitions of HRE were identified and linked with future cardiovascular diseases. Forty-one studies defined HRE at a peak systolic blood pressure (SBP) above or equal to 200 mmHg in men and 25 studies for 190 mmHg in women. Peak diastolic blood pressure (DBP) between 90 and 110 mmHg was reported in 14 studies, relative DBP increase in four. Eight studies defined HRE as SBP between 160 and 200 mmHg at 100 watts. 17 studies performed submaximal exercise testing, while two more looked at BP during recovery. A plethora of other definitions was identified. In athletes, total workload and average blood pressure during exercise were considerably higher. Based on the presented data, the most commonly used definition of HRE at peak exercise is 210/105 mmHg for men, 190/105 mmHg for women, and 220/210 mmHg for athletes. Furthermore, a uniform exercise testing protocol, a position statement by leading experts to unify the definition of HRE, and prospective studies are warranted to confirm these cut-offs and the associated morbidity and mortality.

Abstract
In this cohort study, we determined time to blood pressure (BP) control and its predictors among hypertensive PLHIV enrolled in integrated hypertension-HIV care based on the World Health Organization (WHO) HEARTS strategy at Mulago Immunosuppression Clinic in Uganda. From August 2019 to March 2020, we enrolled hypertensive PLHIV aged ≥ 18 years and initiated Amlodipine 5 mg mono-therapy for BP (140-159)/(90-99) mmHg or Amlodipine 5 mg/Valsartan 80 mg duo-therapy for BP ≥ 160/90 mmHg. Patients were followed with a treatment escalation plan until BP control, defined as BP < 140/90 mmHg. We used Cox proportional hazards models to identify predictors of time to BP control. Of 877 PLHIV enrolled (mean age 50.4 years, 62.1% female), 30% received mono-therapy and 70% received duo-therapy. In the monotherapy group, 66%, 88% and 96% attained BP control in the first, second and third months, respectively. For patients on duo-therapy, 56%, 83%, 88% and 90% achieved BP control in the first, second, third, and fourth months, respectively. In adjusted Cox proportional hazard analysis, higher systolic BP (aHR 0.995, 95% CI 0.989-0.999) and baseline ART tenofovir/lamivudine/efavirenz (aHR 0.764, 95% CI 0.637-0.917) were associated with longer time to BP control, while being on ART for >10 years was associated with a shorter time to BP control (aHR 1.456, 95% CI 1.126-1.883). The WHO HEARTS strategy was effective at achieving timely BP control among PLHIV. Additionally, monotherapy anti-hypertensive treatment for stage I hypertension is a viable option to achieve BP control and limit pill burden in resource limited HIV care settings.
