Association between pre-hypertension and cardiovascular outcomes: a systematic review and meta-analysis of prospective studies

Associations between central and brachial blood pressure in patients with hypertension and aortovascular disease: Implications for clinical practice

Central blood pressure (CBP) measurements, compared to brachial blood pressure (bBP), offer a superior predictive accuracy for aortovascular disease outcomes. This emphasises the distinctiveness of central hemodynamic metrics such as CBP, measuring the pressure directly exerted from the cardiac muscle to the major arteries, and provides a more direct assessment of cardiovascular workload than bBP, which measures the pressure against peripheral artery walls. This review synthesises findings evaluating the correlation between CBP and key aortovascular disease markers. Thoracic aortic aneurysm (TAA) growth is a crucial aspect of aortovascular assessment. CBP more accurately correlates with arterial stiffness (AS), the growth of TAA, and cardiovascular diseases, offering a more dependable prediction of aortovascular diseases, adverse cardiovascular events (CVE) and organ damage compared to bBP. The incorporation of CBP into routine clinical practice could enhance aortovascular assessments and therapeutic strategies when compared to bBP, particularly through a deeper understanding of aortic wave dynamics, which could fundamentally alter aortovascular diagnostics and treatment. In conclusion, integrating CBP into aortovascular and cardiovascular risk management is encouraged. Further research is necessary to substantiate these aspects and explore the operative implications of CBP in clinical settings.

Association between blood pressure multi-trajectory and cardiovascular disease among a Chinese elderly medical examination population

Objective

This study aimed to characterize multivariate trajectories of blood pressure [systolic blood pressure (SBP) and diastolic blood pressure (DBP)] jointly and examine their impact on incident cardiovascular disease (CVD) among a Chinese elderly medical examination population.

Methods

A total of 13,504 individuals without CVD during 2018-2020 were included from the Chinese geriatric physical examination cohort study. The group-based trajectory model was used to construct multi-trajectories of systolic blood pressure and diastolic blood pressure. The primary outcome was the incidence of the first CVD events, consisting of stroke and coronary heart diseases, in 2021. The Cox proportional hazards model was used to calculate the hazard ratios (HRs) and 95% confidence intervals (CIs) for the association between BP multi-trajectories and incident CVD events.

Results

We identified four blood pressure (BP) subclasses, summarized by their SBP and DBP levels from low to high as class 1 (7.16%), class 2 (55.17%), class 3 (32.26%), and class 4 (5.41%). In 2021, we documented 890 incident CVD events. Compared with participants in class 1, adjusted HRs were 1.56 (95% CI: 1.12-2.19) for class 2, 1.75 (95% CI: 1.24-2.47) for class 3, and 1.88 (95% CI: 1.24-2.85) for class 4 after adjustment for demographics, health behaviors, and metabolic index. Individuals aged 65 years and above with higher levels of BP trajectories had higher risks of CVD events in China.

Conclusions

Individuals with higher levels of both SBP and DBP trajectories over time were associated with an increased risk of incident CVD in the Chinese elderly population.

Prospective associations between systolic blood pressure, serum cholesterol, and physical activity behaviour and the development of cardiovascular disease

AIMS

To systematically appraise and summarise meta-analyses of longitudinal studies to determine the effect size, and quality and certainty of the evidence summaries for systolic blood pressure (SBP), serum cholesterol, and physical activity behaviour in developing cardiovascular disease (CVD).

METHODS AND RESULTS

An umbrella review was conducted by searching MEDLINE, Embase, and Scopus databases. Eligible meta-analyses were longitudinal studies investigating the association between SBP, serum cholesterol, or physical activity behaviour on CVD development. Summary risk estimates were extracted. Quality and certainty of the evidence summaries of included records were performed using AMSTAR 2 and GRADE, respectively. Forty-one eligible records were found of which thirteen related to SBP, five to cholesterol, and twenty-three to physical activity behaviour. The quality and certainty of the evidence summaries were variable, with most studies rating 'low'. Reported risk estimates for the risk of developing CVD ranged from: no change to a 68% decreased risk for lower SBP; a 21% increased risk to a 44% decreased risk for lower cholesterol; and a 1% decreased risk to a 56% decreased risk for higher physical activity levels.

CONCLUSIONS

There were strong associations with CVD risk at the meta-analysis level for all three exposures, with a proportionally greater number of meta-analyses and primary studies for physical activity than SBP or serum cholesterol. Given the number of meta-analyses and similar CVD risk reductions and certainty of evidence associated with physical activity behaviour, there is a strong case for its routine assessment alongside SBP and serum cholesterol in primary CVD prevention.

Evaluation of New Hypertension Guidelines on the Prevalence and Control of Hypertension in a Clinical HIV Cohort: A Community-Based Study

The prevalence and control of hypertension (HTN) among people with HIV (PWH) have not been widely studied since the release of newer 2017 ACC/AHA guidelines ("new guidelines"). To address this research gap, we evaluated and compared the prevalence and control of HTN using both 2003 JNC 7 ("old guidelines") and new guidelines. We identified 3,206 PWH with HTN from the DC Cohort study in Washington, DC, between January 2018 and June 2019. We defined HTN using International Classification of Diseases (ICD)-9/-10 diagnosis codes for HTN or ≥2 blood pressure (BP) measurements obtained at least 1 month apart (>139/89 mm Hg per old or >129/79 mm Hg per new guidelines). We defined HTN control based on recent BP (≤129/≤79 mm Hg per new guidelines). We identified socio-demographics, cardiovascular risk factors, and co-morbidities associated with HTN control using multivariable logistic regression [adjusted odds ratio (aOR); 95% confidence interval (CI)]. The prevalence of HTN was 50.9% per old versus 62.2% per new guidelines. Of the 3,206 PWH with HTN, 887 (27.7%) had a recent BP ≤129/≤79 mm Hg, 1,196 (37.3%) had a BP 130-139/80-89 mm Hg, and 1,123 (35.0%) had a BP ≥140/≥90 mm Hg. After adjusting for socio-demographics, cardiovascular risk factors, and co-morbidities, factors associated with HTN control included age 60-69 (vs. <40) years (aOR: 1.42; 95% CI: 1.03-1.98), Hispanic (vs. non-Hispanic Black) race/ethnicity (aOR 1.49; 95% CI: 1.04-2.15), receipt of HIV care at a hospital-based (vs. community-based) clinic (aOR 1.21; 95% CI: 1.00-1.47), being unemployed (aOR 1.42; 95% CI: 1.11-1.83), and diabetes (aOR 1.35; 95% CI: 1.13-1.63). In a large urban cohort of PWH, nearly two-thirds had HTN and less than one-third of those met new guideline criteria. Our data suggest that more aggressive HTN control is warranted among PWH, with additional attention to younger patients and non-Hispanic Black patients.

Long-term effects of blood pressure 130-139/80-89 mmHg on all-cause and cardiovascular mortality among Chinese adults with different glucose metabolism

BACKGROUND

This study aimed to investigate the risks of all-cause and cardiovascular mortality associated with blood pressure (BP) levels of 130-139/80-89 mmHg in Chinese adults with different glucose metabolism, during a long-term follow-up of over 20 years.

METHODS

A prospective population-based cohort of 2,132 adults in Shanghai was established in 2002 and followed for 21 years. The association between BP categories and mortality was assessed, and the risk was further analyzed using multiple Cox regression analysis by combining BP and blood glucose categories.

RESULTS

The final analysis included 2,004 participants, with 397 all-cause and 166 cardiovascular mortality. The incidence of all-cause and cardiovascular mortality per 1,000 person-years for different BP categories were as follows: BP < 130/80 mmHg (4.5 and 1.3), 130-139/80-89 mmHg (7.7 and 2.9), and ≥ 140/90 mmHg or treated groups (19.9 and 8.7), respectively. After adjusting for age, sex, and other factors, BP ≥ 140/90 mmHg was significantly associated with a higher risk of mortality across different blood glucose categories. However, using BP < 130/80 mmHg and normoglycemia as the reference, a BP of 130-139/80-89 mmHg was significantly associated with higher risks of all-cause (hazard ratio 3.30 [95% confidence interval 1.48-7.38], P < 0.01) and cardiovascular mortality (9.60 [1.93-47.7], P < 0.01) in diabetes, but not in those with normoglycemia or prediabetes.

CONCLUSIONS

BP of 130-139/80-89 mmHg may lead to a significantly higher risk of all-cause and cardiovascular mortality in Chinese adults with diabetes, but not in those with normoglycemia or prediabetes. This suggests that the targeted BP for people with diabetes should be < 130-139/80-89 mmHg.

What is the most appropriate follow-up time for detecting the epidemiological relationship between coronary artery disease and its main risk factors: novel findings from a 35-year follow-up study

BACKGROUND

The aim was to investigate the most appropriate follow-up time to detect the associations of coronary artery disease (CAD) with its traditional risk factors in a long-term prospective cohort study.

METHODS

The Kuopio Ischaemic Heart Disease Risk Factors Study provided the study material of 1958 middle-aged men free from CAD at baseline and followed up for 35 years. We performed Cox models adjusted for age, family history, diabetes, obesity, hypercholesterolemia, hypertension, smoking, and physical activity, investigated covariate interactions, and tested Schoenfeld residuals to detect time-dependent covariates. Moreover, we applied a sliding window procedure with a subarray of 5 years to better differentiate between risk factors manifested within years and those manifested within decades. The investigated manifestations were CAD and fatal acute myocardial infarction (AMI).

RESULTS

Seven hundred seventeen (36.6%) men had CAD, and 109 (5.6%) men died from AMI. After 10 years of follow-up, diabetes became the strongest predictor of CAD with a fully adjusted hazard ratio (HR) of 2.5-2.8. During the first 5 years, smoking was the strongest predictor (HR 3.0-3.8). When the follow-up time was 8-19 years, hypercholesterolemia predicted CAD with a HR of >2. The associations of CAD with age and diabetes depended on time. Age hypertension was the only statistically significant covariate interaction. The sliding window procedure highlighted the significance of diabetes over the first 20 years and hypertension after that. Regarding AMI, smoking was associated with the highest fully adjusted HR (2.9-10.1) during the first 13 years. The associations of extreme and low physical activity with AMI peaked when the follow-up time was 3-8 years. Diabetes showed its highest HR (2.7-3.7) when the follow-up time was 10-20 years. During the last 16 years, hypertension was the strongest predictor of AMI (HR 3.1-6.4).

CONCLUSION

The most appropriate follow-up time for most CAD risk factors was 10-20 years. Concerning smoking and hypertension shorter and longer follow-up times could be considered, respectively, particularly when studying fatal AMI. In general, prospective cohort studies of CAD would provide more comprehensive results by reporting point estimates in relation to more than one timepoint and concerning sliding windows.

Blood Pressure and Cardiovascular Disease Mortality Among US Adults: A Sex-Stratified Analysis, 1999-2019

BACKGROUND

Most research examining the association between blood pressure (BP) and cardiovascular disease (CVD) is sex-agnostic. Our goal was to assess sex-specific associations between BP and CVD mortality.

METHODS

We combined ten cycles of the National Health and Nutrition Examination Survey (1999-2018), N=53 289. Blood pressure was measured 3× and averaged. Data were linked to National Death Index data, and CVD mortality through December 31, 2019, was defined from International Classification of Diseases, Tenth Revision codes. We estimated sex-stratified, multivariable-adjusted incidence rate ratios (IRRs) for CVD mortality.

RESULTS

Over a median follow-up of 9.5 years, there were 2405 CVD deaths. Associations between categories of systolic blood pressure (SBP) and diastolic blood pressure (DBP) with CVD mortality differed by sex (P<0.01). Among men, compared with SBP of 100 to <110 mm Hg, CVD mortality was 76% higher with SBP ≥160 mm Hg (IRR, 1.76 [95% CI, 1.27-2.44]). Among women, compared with SBP 100 to < 110 mm Hg, CVD mortality was 61% higher with SBP 130 to 139 mm Hg (IRR, 1.61 [95% CI, 1.02-2.55]), 75% higher with SBP 140 to 159 mm Hg (IRR, 1.75 [95% CI, 1.09-2.80]), and 113% higher with SBP≥160 mm Hg (IRR, 2.13 [95% CI, 1.35-3.36]). Compared with DBP 70 to <80 mm Hg, CVD mortality was higher with DBP <70 mm Hg and DBP≥80 mm Hg among men, and higher with DBP <50 mm Hg and DBP≥80 mm Hg among women.

CONCLUSIONS

The association between BP and CVD mortality differed by sex, with increased CVD mortality risk present at lower levels of systolic blood pressure among women compared with men.

Change in blood pressure status defined by 2017 ACC/AHA hypertension guideline and risk of cardiovascular disease: results of over a decade of follow-up of the Iranian population

Background

Hypertension (HTN) is known to be the leading cause of cardiovascular disease (CVD) and mortality. We aimed to assess the impact of changes in 3 years in different blood pressure (BP) categories on incident CVD.

Methods

In this study, 3,685 Tehranians aged ≥30 years (42.2% men) free of prevalent CVD with BP level <140/90 mmHg and not on BP-lowering medications were enrolled. Participants were grouped according to baseline BP category using the 2017 ACC/AHA hypertension guideline definition: normal BP (<120/80 mmHg), elevated BP (120-129/<80), and stage 1 HTN (130-139 and/or 80-89). The hazard ratio of incident CVD by changes in the BP category was estimated after adjustment for traditional risk factors using Cox's proportional hazard model, with stable normotension as a reference.

Results

During a median follow-up of 11.7 years, 346 CVD events (men = 208) occurred. Compared to the reference group, among participants with normal BP at baseline, only those with BP rising to stage 1 HTN [1.47 (0.99-2.16)], and among those with stage 1 HTN at baseline, regression to elevated BP [1.80 (1.11-2.91)], remaining at stage 1 [1.80 (1.29-2.52)], and progression to stage 2 HTN [1.81 (1.25-2.61)] had a higher risk for CVD; however, regression to normal BP attenuated this risk [1.36 (0.88-2.12)]. Conversion from elevated BP to any other categories had no significant association with CVD risk.

Conclusions

Generally, prevalent stage 1 HTN (regardless of changing category) and incident stage 1 HTN were significantly associated with a higher risk of CVD; even regression to elevated BP did not attenuate the risk. Accordingly, these populations are potential candidates for antihypertensive management.

The effect of prehypertension and hypertension on the incidence of cardiovascular disease: A population-based cohort study in Kharameh, a city in the South of Iran

Background and Aim

Prehypertension and hypertension are important risk factors for cardiovascular diseases. This study was carried out to evaluate the effect of prehypertension and hypertension on the development of cardiovascular diseases.

Methods

This prospective cohort study was performed on 9442 people aged 40-70 in Kharameh, southern Iran. Individuals were divided into three groups: normal blood pressure (N = 5009), prehypertension (N = 2166), and hypertension (N = 2267). In this study, demographic data, disease histories, behavioral habits, and biological parameters were studied. At first, the incidence density was calculated. Then Firth's Cox regression models were used to investigate the association between prehypertension and hypertension with the incidence of cardiovascular diseases.

Results

The incidence density in the three groups of individuals with normal blood pressure, prehypertension, and hypertension was 1.33, 2.02, and 3.29 cases per 100,000 person-days, respectively. The results of multiple Firth's Cox regression by controlling all factors showed that the risk of occurrence of cardiovascular disease in people with prehypertension was 1.33 times (hazard ratio [HR] = 1.32, 95% confidence interval [CI]: 1.01-1.73, p = 0.03) and those with hypertension were 1.85 times higher (HR = 1.77, 95% CI: 1.38-2.29, p < 0.0001) than the individuals with normal blood.

Conclusion

Prehypertension and hypertension have played an independent role in the risk for developing cardiovascular diseases. Therefore, early detection of individuals with these factors and control of other risk factors in them can contribute to reducing the occurrence of cardiovascular diseases.

Prevalence and associated factors for prehypertension and hypertension among Indonesian adolescents: a cross-sectional community survey

OBJECTIVE

To estimate the prevalence and determine the associated factors for developing prehypertension and hypertension among Indonesian adolescents.

DESIGN

National cross-sectional study.

SETTING

This study was conducted in all the provinces in Indonesia.

PARTICIPANTS

The population in this study were all household members in Basic Health Research 2013 aged 15-19 years. The sample was all members of the 2013 Riskesdas household aged 15-19 years with the criteria of not having physical and mental disabilities, and having complete data. The number of samples analysed was 2735, comprising men (n=1319) and women (n=1416).

MAIN OUTCOME

Dependent variables were prehypertension and hypertension in adolescents based on blood pressure measurements.

RESULTS

The results of the analysis showed that the prevalence of prehypertension in adolescents was 16.8% and hypertension was 2.6%. In all adolescents, the risk factors for prehypertension were boys (adjusted OR, aOR 1.48; 95% CI 1.10 to 1.97), 18 years old (aOR 14.64; 95% CI 9.39 to 22.80), and 19 years old (aOR 19.89; 95% CI 12.41 to 31.88), and obese (aOR 2.16; 95% CI 1.02 to 4.58). Risk factors for hypertension in all adolescents included the age of 18 years old (aOR 3.06; 95% CI 1.28 to 7.34) and 19 years (aOR 3.25; 95% CI 1.25 to 8.41) and obesity (aOR 5.69; 95% CI 2.20 to 14.8). In adolescent girls, the chance of developing prehypertension increased with increasing age and low-density lipoprotein (LDL) cholesterol levels. Several risk factors for hypertension in adolescent boys were age, central obesity and LDL cholesterol levels.

CONCLUSION

This study shows that the trend of prehypertension in adolescents has appeared, besides hypertension. There are distinct patterns of factors that influence it in adolescent girls and boys, which can be useful to sharpen of planning and implementing health programmes.

SAGE Score in Normotensive and Pre-Hypertensive Patients: A Proof of Concept

BACKGROUND

The SAGE score was developed to detect individuals at risk for increased pulse wave velocity (PWV). So far, studies have been focused on hypertensive patients.

OBJECTIVE

To assess the ability of the score to detect non-hypertensive and pre-hypertensive patients at risk for increased PWV.

METHODS

Retrospective cross-sectional study of analysis of central blood pressure data and calculation of the SAGE score of non-hypertensive and pre-hypertensive patients. Each score point was analyzed for sensitivity, specificity, positive and negative predictive values, using the cut-off point for positive diagnosis a PVW ≥ 10m/s, ≥9.08 m/s (75thpercentile) and ≥7.30 m/s (50thpercentile). A p<0.05 was considered statistically significant.

RESULTS

The sample was composed of 100 normotensive and pre-hypertensive individuals, with mean age of 52.64 ± 14.94 years and median PWV of 7.30 m/s (6.03 - 9.08). The SAGE score was correlated with age (r=0.938, p<0.001), glycemia (r=0.366, p<0.001) and glomerular filtration rate (r=-0.658, p<0.001). The area under the ROC curve was 0.968 (p<0.001) for PWV ≥ 10 m/s, 0.977 (p<0.001) for PWV ≥ 9.08 m/s and 0.967 (p<0.001) for PWV ≥ 7.30 m/s. The score 7 showed a specificity of 95.40% and sensitivity of 100% for PWV≥10 m/s. The cut-off point would be of five for a PWV≥9.08 m/s (sensitivity =96.00%, specificity = 94.70%), and two for a PWV ≥ 7.30 m/s.

CONCLUSION

The SAGE score could identify individuals at higher risk of arterial stiffness, using different PWV cutoff points. However, the development of a specific score for normotensive and pre-hypertensive subjects is needed.

Decompression Mechanism of Radish Seed in Prehypertension Rats through Integration of Transcriptomics and Metabolomics Methods

Radish seed (RS), the dried ripe seed of Raphanus sativus L., is widely used in traditional Chinese medicine (TCM) to reduce blood pressure. However, the molecular and pharmacological mechanisms underlying its therapeutic effects are still unclear. In this study, we analyzed the effects of RS in a rat model of prehypertension and assessed the mechanistic basis by integrating transcriptomics and metabolomics. RS administration significantly reduced blood pressure in prehypertensive male Wistar rats, negatively regulated endothelin-1, increased nitric oxide levels, and reduced the exfoliation of endothelium cells. In vitro vascular ring experiments further confirmed the effects of RS on vascular endothelial cells. Furthermore, we identified 65 differentially expressed genes (DEGs; P _adj < 0.05 and fold change (FC) > 2) and 52 metabolites (VIP > 1, P < 0.05 and FC ≥ 2 or ≤0.5) in the RS intervention group using RNA-seq and UPLC-MS/MS, respectively. A network of the DEGs and the metabolites was constructed,q which indicated that RS regulates purine metabolism, linoleic acid metabolism, arachidonic acid metabolism, circadian rhythm, and phosphatidylinositol signaling pathway, and its target genes are Pik3c2a, Hspa8, Dnaja1, Arntl, Ugt1a1, Dbp, Rasd1, and Aldh1a3. Thus, the antihypertensive effects of RS can be attributed to its ability to improve vascular endothelial dysfunction by targeting multiple genes and pathways. Our findings provide new insights into the pathological mechanisms underlying prehypertension, along with novel targets for the prevention and treatment of hypertension.

Occupational Noise-Induced Pre-Hypertension and Determinant Factors Among Metal Manufacturing Workers in Gondar City Administration, Northwest Ethiopia

Introduction

Cardiovascular disorders are one of the commonly recognized occupational diseases in the developed world. Individuals chronically exposed to noise at workplaces had a higher risk of developing elevated arterial blood pressure. There are limited studies in Ethiopia regarding this topic and thus this study determined the prevalence and determinant factors of occupational noise-induced pre-hypertension among metal manufacturing workers in Gondar city administration, Northwest Ethiopia.

Methods

An institution-based cross-sectional study design was carried out. In this study, 300 study participants were recruited by census sampling method. A sound level meter was used to measure the working area noise level. A semi-structured pre-tested interviewer-administered questionnaire was used to collect sociodemographic and clinical data. Blood pressure was measured in a quiet room in the morning using a mercurial sphygmomanometer. Both bivariable and multi-variable binary logistic regressions were used to identify factors associated with noise-induced prehypertension. Adjusted odds ratio with 95% confidence interval was reported, and variables with p < 0.05 were considered as statistically associated factors with pre-hypertension.

Results

The prevalence of noise-induced pre-hypertension was 27.7% (95% CI: 22.7-32.7). In multivariable logistic regression, working area noise level (AOR = 3.8, 95% CI: 6.8-8.9), 45-65 years' age (AOR = 9.8, 95% CI: 5.4-12.9), years of work experience ((6-10 years (AOR = 2.8, 95% CI: 1.98-5.90 and >10 years (AOR = 4.8, 95% CI: 7.8-9.75)), being a cigarette smoker (AOR = 3.6, 95% CI: 1.36-9.77), and alcohol consumption (AOR = 2.4, 95% CI: 1.06-1.04) were significantly associated with noise-induced prehypertension.

Conclusion

Workers in metal manufactures who were exposed to noise levels >85 dB developed elevated blood pressure. The odds of having prehypertension were increased by years of work experience, advanced age, smoking, and alcohol consumption. Our findings recommended that the real-world preventive strategies should be taken to lower the risk of noise-induced pre-hypertension hastened by occupational noise exposure.

Early Stage and Established Hypertension in Sub-Saharan Africa: Results From Population Health Surveys in 17 Countries, 2010-2017

BACKGROUND

Multiple studies have reported a high burden of hypertension in sub-Saharan Africa, but none have examined early stage hypertension. We examined contemporary prevalence of diagnosed, treated, and controlled stage I (130-139/80-89 mm Hg) and II (≥140/90 mm Hg) hypertension in the general population of sub-Saharan Africa.

METHODS

We analyzed World Health Organization STEPwise Approach to Noncommunicable Disease Risk Factor Surveillance surveys from 17 sub-Saharan Africa countries including 85 371 respondents representing 85 million individuals from 2010 to 2017. We extracted demographic variables, blood pressure, self-reported hypertension diagnosis/awareness, and treatment status to estimate prevalence of stage I and II hypertension and treatment by country. We examined diagnosis and treatment trends by national sociodemographic index, a marker of development.

RESULTS

Stage I hypertension prevalence (regardless of diagnosis/treatment) was >25% in 13 of 17 countries, highest in Sudan (35.3% [95% CI, 33.7%-37.0%]), and lowest in Eritrea (20.2% [18.8%-21.6%]). Combined stages I and II hypertension prevalence was >50% in 13 countries; <20% were diagnosed in every country. Treatment among those diagnosed ranged from 26% to 63%, and control (<140/90 mm Hg) from 4% to 17%. In 8 of 9 countries reporting on behavioral interventions (eg, salt reduction, weight loss, exercise, and smoking cessation), <60% of diagnosed individuals received counseling. Rates of diagnosis, but not treatment, were positively associated with sociodemographic index (P=0.008), although there was substantial variation between countries even at similar levels of development.

CONCLUSIONS

Hypertension is common in sub-Saharan Africa but rates of diagnosis, treatment, and control markedly low. There is a large population with early stage hypertension that may benefit from behavioral counseling to prevent progression. Our analyses suggest that success in population hypertension care may be achieved independently of socioeconomic development, highlighting a need for policymakers to identify best practices in those countries that outperform similar or more developed countries.

National levels, changes and correlates of ideal cardiovascular health among Beninese adults: evidence from the 2008 to 2015 STEPS surveys

Introduction

A higher number of ideal cardiovascular health (CVH) metrics is associated with a lower risk of cardiovascular-related and all-cause mortality. However, the change in CVH metrics has rarely been studied in sub-Saharan Africa. We investigated the level and changes of CVH metrics and their correlates among Beninese adults between 2008 and 2015.

Methods

Secondary analysis was performed on data obtained from Benin's 2008 and 2015 WHO Stepwise surveys (STEPS). In total, 3617 and 3768 participants aged 25-64 years were included from both surveys, respectively. CVH metrics were assessed using the American Heart Association definition, which categorised smoking, fruit and vegetable consumption, physical activity, body mass index (BMI), blood pressure (BP), total cholesterol (TC) and glycaemia into 'ideal', 'intermediate' and 'poor' CVH. The prevalence of ideal CVH metrics was standardised using the age and sex structure of the 2013 population census.

Results

Few participants met all seven ideal CVH metrics, and ideal CVH significantly declined between 2008 and 2015 (7.1% (95% CI 6.1% to 8.1%) and 1.2% (95% CI 0.8% to 1.5%), respectively). The level of poor smoking (8.0% (95% CI 7.1% to 8.9%) and 5.6% (95% CI 4.8% to 6.3%)) had decreased, whereas that of poor BP (25.9% (95% CI 24.5% to 27.4%) and 32.0% (95% CI 30.0% to 33.5%)), poor total cholesterol (1.5% (95% CI 1.0% to 1.9%) and 5.5% (95% CI 4.8% to 6.2%)) and poor fruit and vegetable consumption (34.2% (95% CI 32.4% to 35.9%) and 51.4% (95% CI 49.8% to 53.0%)) significantly increased. Rural residents and young adults (25-34 years) had better CVH metrics.

Conclusion

The proportion of adults with ideal CVH status was low and declined significantly between 2008 and 2015 in Benin, emphasising the need for primordial prevention targeting urban areas and older people to reduce the burden of cardiovascular disease risk factors.

Inspiratory muscle strength training for lowering blood pressure and improving endothelial function in postmenopausal women: comparison with “standard of care” aerobic exercise

Background: High blood pressure (BP), particularly systolic BP (SBP), is the major modifiable risk factor for cardiovascular diseases and related disorders of aging. SBP increases markedly with aging in women such that the prevalence of above-normal SBP (i.e., ≥120 mmHg) in postmenopausal women exceeds rates in age-matched men. This increase in SBP is associated with vascular endothelial dysfunction, mediated by excessive reactive oxygen species-induced oxidative stress and consequent reductions in nitric oxide bioavailability. Moderate-intensity aerobic exercise is a recommended lifestyle strategy for reducing SBP. However, adherence to aerobic exercise guidelines among postmenopausal women is low (<30%) and aerobic exercise does not consistently enhance endothelial function in estrogen-deficient postmenopausal women. High-resistance inspiratory muscle strength training (IMST) is a time-efficient, adherable lifestyle intervention that involves inhaling against resistance through a handheld device (30 breaths/day). Here, we present the protocol for a randomized controlled trial investigating the efficacy of 3 months of high-resistance IMST compared to guideline-based, “standard-of-care” aerobic exercise training for decreasing SBP and improving endothelial function in estrogen-deficient postmenopausal women with above-normal SBP (120–159 mmHg) at baseline (ClinicalTrials.gov Identifier: NCT05000515).

Methods: A randomized, single-blind, parallel-group design clinical trial will be conducted in 72 (36/group) estrogen-deficient postmenopausal women with above-normal SBP. Participants will complete baseline testing and then be randomized to either 3 months of high-resistance IMST (30 breaths/day, 6 days/week, 75% maximal inspiratory pressure) or moderate-intensity aerobic exercise training (brisk walking 25 min/day, 6 days/week, 40–60% heart rate reserve). Outcome measures will be assessed after 3 months of either intervention. Following end-intervention testing, participants will abstain from their assigned intervention for 6 weeks, after which BP and endothelial function will be assessed to evaluate the potential persistent effects of the intervention on the primary and secondary outcomes.

Discussion: This study is designed to compare the effectiveness of time-efficient, high-resistance IMST to guideline-based aerobic exercise training for lowering SBP and improving endothelial function, and interrogating potential mechanisms of action, in estrogen-deficient postmenopausal women.

Clinical Trial Registration:ClinicalTrials.gov, Identifier: NCT05000515.

Pharmacological Management of Primary Arterial Hypertension: A Century of Expert Opinions in Cecil Textbook of Medicine

BACKGROUND

Advances in drug therapy for primary (or essential) arterial hypertension have contributed to a significant decrease in the frequency and severity of strokes, coronary artery disease and heart failure, and chronic renal insufficiency.

STUDY QUESTION

What are the milestones of the changes in the expert approach to the pharmacological management of arterial hypertension in the past century?

STUDY DESIGN

To determine the changes in the experts' approach to the management of arterial hypertension, as presented in a widely used textbook in the United States.

DATA SOURCES

The chapters presenting the management of arterial hypertension in the 26 editions of Cecil Textbook of Medicine published from 1927 through 2020.

RESULTS

The pharmacological management of arterial hypertension has had 3 overlapping eras in the timeframe subject to our investigation. In the empiric era (1927-1947), experts were recommending nonspecific interventions for sedation. The premodern era (1955-1963) relied on ganglion blockers, sympathetic blockers, and direct vasodilators. The modern era (1967-2020), which includes drugs used in current clinical practice, saw the introduction of diuretics (1967), beta-blockers (1971), alpha-blockers (1982), calcium channel blockers (1985), angiotensin-converting enzyme inhibitors (1985), angiotensin receptor blockers (2000), and direct renin inhibitors (2008).

CONCLUSIONS

The pharmacological management of arterial hypertension has been the focus of intense and successful research and development in the second half of the 20th century.

Severity of Nonalcoholic Fatty Liver Disease is Associated With Cardiovascular Outcomes in Patients With Prehypertension or Hypertension: A Community-Based Cohort Study

BACKGROUND

It is unclear whether more severe non-alcoholic fatty liver disease (NAFLD) combined with prehypertension or hypertension is associated with a higher risk of cardiovascular events (CVEs). To evaluate the relationship between the severity of NAFLD and CVEs among patients with prehypertension or hypertension.

METHODS

In this prospective community-based Kailuan cohort, participants without cardiovascular disease and alcohol abuse, or other liver diseases were enrolled. NAFLD was diagnosed by abdominal ultrasonography. Prehypertension was defined as systolic blood pressure (BP) of 120-139 mmHg or diastolic BP of 80-89 mmHg. Participants with NAFLD were divided into mild, moderate, and severe subgroups. Follow-up for CVEs including myocardial infarction, hemorrhagic stroke, and ischemic stroke. The Cox proportional hazards model was used to estimate hazard ratios and 95% CIs of CVEs according to the severity of NAFLD and hypertensive statutes. The C-statistic was used to evaluate the efficiency of models.

RESULTS

A total of 71926 participants (mean [SD] age, 51.83 [12.72] years, 53794 [74.79%] men, and 18132 [25.21%] women) were enrolled in this study, 6,045 CVEs occurred during a median of 13.02 (0.65) years of follow-up. Compared with participants without NAFLD, the hazard ratios of CVEs for patients with mild, moderate, and severe NAFLD were 1.143 (95% CI 1.071-1.221, P < 0.001), 1.218 (95% CI 1.071-1.221, P < 0.001), and 1.367 (95% CI 1.172-1.595, P < 0.001), respectively. Moreover, participants with prehypertension plus moderate/severe NAFLD and those with hypertension plus moderate/severe NAFLD had 1.558-fold (95% CI 1.293-1.877, P < 0.001) and 2.357-fold (95% CI 2.063-2.691, P < 0.001) higher risks of CVEs, respectively, compared with those with normal BP and no NAFLD. Adding a combination of NAFLD and BP status to the crude Cox model increased the C-statistic by 0.0130 (0.0115-0.0158, P < 0.001).

CONCLUSIONS

Our findings indicated that the increased cardiovascular risk with elevated BP is largely driven by the coexistence of moderate/severe NAFLD, suggesting that the severity of NAFLD may help further stratify patients with prehypertension and hypertension.

Hypertension and pre-hypertension in Middle East and North Africa (MENA): A meta-analysis of prevalence, awareness, treatment, and control

Hypertension (HTN) is one of the most important public health challenges, especially in developing countries. Despite individual studies, information on the exact prevalence of prehypertension (pre-HTN) and HTN in the Middle East and North Africa (MENA) is lacking. This meta-analysis was conducted to evaluate prevalence of pre-HTN and HTN, awareness, treatment, and control in the MENA region. PubMed, Web of Science, and Scopus databases were searched from inception to April 30, 2021. Keywords included hypertension, pre-hypertension, awareness, treatment, and control. The quality of the included studies was evaluated using the Hoy scale. A random-effects model was evaluated based on overall HTN. The heterogeneity of the preliminary studies was evaluated using the I² test. A total of 147 studies involving 1,312,244 participants were included in the meta-analysis. Based on the results of the random-effects method (95% CI), the Prevalence of pre-HTN and HTN were 30.6% (95% CI: 25.2, 36.0%; I² = 99.9%), and 26.2% (95% CI: 24.6, 27.9%; I² = 99.8%), respectively. The prevalence of HTN awareness was 51.3% (95% CI: 47.7, 54.8; I² = 99.0%). The prevalence of HTN treatment was 47.0% (95% CI: 34.8, 59.2; I² = 99.9%). The prevalence of HTN control among treated patients was 43.1% (95% CI: 38.3, 47.9; I² = 99.3%). Considering the high prevalence of HTN, very low awareness, and poor HTN control in the region, more attention should be paid to preventive programs for HTN reduction.

Incidence and Risk Factors of Cardio-Cerebrovascular Disease in Korean Menopausal Women: A Retrospective Observational Study using the Korean Genome and Epidemiology Study data

PURPOSE

Cardio-cerebrovascular diseases constitute the most common and fatal disease among menopausal women. However, the risk of cardio-cerebrovascular diseases in menopausal women compared to men has been underestimated, with insufficient related studies. Therefore, we examined the incidence and risk factors of cardio-cerebrovascular diseases among Korean menopausal women.

METHODS

A retrospective observational study design with secondary analysis was conducted using data from the Korean Genome and Epidemiology Study survey. We used the study's data of 1,197 menopausal women, aged 40-64 years, who did not have cardio-cerebrovascular diseases at baseline and their related data from the biennial follow-ups over 14 years. Cardio-cerebrovascular diseases were defined as hypertension, coronary artery disease, or stroke. The incidence of cardio-cerebrovascular diseases was calculated per person-years, and multivariate Cox proportional hazards models were used to determine the predictors of cardio-cerebrovascular diseases during the follow-up period.

RESULTS

Of the 1,197 cases, 264 were early or surgical menopausal women. The overall incidence of cardio-cerebrovascular diseases was 18.75 per 1,000 person-years. Early or surgical menopause (HR = 4.32, p < .001), along with family history of cardiovascular disease (HR = 1.87, p = .024), elevated blood pressure (HR = 1.79, p < .001), abdominal obesity (HR = 1.37, p = .046), or duration of menopause at the same age (HR = 1.01, p = .001), were strong predictors of cardio-cerebrovascular diseases.

CONCLUSION

Based on the results of this study, it is necessary to identify and closely monitor women with early or surgical menopause for cardiovascular and cerebrovascular diseases prevention. Also, prevention of cardio-cerebrovascular diseases through blood pressure and abdominal obesity management is vital for menopausal women.

Concordance of recommendations across clinical practice guidelines for the management of hypertension in Southeast Asia with internationally reputable sources

OBJECTIVES

This study aimed to assess the rate of concordance, and to investigate sources of non-concordance of recommendations in the management of hypertension across CPGs in Southeast Asia, with internationally reputable clinical practice guidelines (CPGs).

METHODS

CPGs for the management of hypertension in Southeast Asia were retrieved from the websites of the Ministry of Health or cardiovascular specialty societies of the individual countries of Southeast Asia during November to December 2020. The recommendations for the management of hypertension specified in the 2017 American College of Cardiology (ACC)/American Heart Association (AHA) guideline and the 2018 European Society of Cardiology (ESC)/European Society of Hypertension (ESH) guideline were selected to be the reference standards; the recommendations concerning the management of hypertension in the included CPGs in Southeast Asia were assessed if they were concordant with the reference recommendations generated from both the 2017 ACC/AHA guideline and the 2018 ESC/ESH guideline, using the population (P)-intervention (I)-comparison (C) combinations approach.

RESULTS

A total of 59 reference recommendations with unique and unambiguous P-I-C specifications was generated from the 2017 ACC/AHA guideline. In addition, a total of 51 reference recommendations with unique and unambiguous P-I-C specifications was generated from the 2018 ESC/ESH guideline. Considering the six included CPGs from Southeast Asia, concordance was observed for 30 reference recommendations (50.8%) out of 59 reference recommendations generated from the 2017 ACC/AHA guideline and for 31 reference recommendations (69.8%) out of 51 reference recommendations derived from the 2018 ESC/ESH guideline.

CONCLUSIONS

Hypertension represents a significant issue that places health and economic strains in Southeast Asia and demands guideline-based care, yet CPGs in Southeast Asia have a high rate of non-concordance with internationally reputable CPGs. Concordant recommendations could perhaps be considered a standard of care for hypertension management in the Southeast Asia region.

Diabetes modifies the association of prehypertension with cardiovascular disease and all-cause mortality

Prehypertension is a risk factor for cardiovascular disease (CVD) and all‐cause mortality. However, it is unclear whether prehypertension combined with diabetes associate with a higher risk for cardiovascular disease and all‐cause mortality. The purpose of this study was to explore the relationship between prehypertension and the risk of CVD and all‐cause mortality was different among individuals with or without diabetes. In the prospective community‐based Kailuan study, 67 344 participants without hypertension or a history of CVD at baseline (2006) were included. Prehypertension was defined as systolic blood pressure of 120–139 mmHg or diastolic blood pressure of 80–89 mmHg. The outcomes were CVD and all‐cause mortality were followed up through December 31, 2017. We performed Cox proportional hazards models to evaluate the relationships between prehypertension and CVD and all‐cause mortality by diabetes status. During a median follow‐up of 11.03 years, 2981 CVD events and 4655 all‐cause mortality occurred. After adjusting age, sex, and other factors, the associations of prehypertension with risk of CVD and all‐cause mortality were significant in participants without diabetes (hazard ratio and 95% confidence interval: 1.54 [1.38–1.71] and 1.27 [1.17–1.38]), but not in participants with diabetes (1.20 [0.93–1.56] and 0.88 [0.73–1.07]). The interactions between prehypertension and diabetes for the risk of CVD and all‐cause mortality were all significant (all p < .05). Prehypertension was only associated with an increased risk for CVD and all‐cause mortality in non‐diabetes participants. Diabetes modifies the relation of prehypertension with the risk of CVD and all‐cause mortality.

Exercise-related blood pressure response is related to autonomic modulation in young adults: A new extension study

BACKGROUND:

The delayed blood pressure recovery (BPR) at post-exercise has been in association with a major risk of cardiovascular disease and death.

OBJECTIVE:

The study focused on evaluating the systolic and diastolic blood pressure recovery (SBPR, DBPR) and the autonomic modulation following treadmill exercise in healthy young adults. Although considerable literature had been published about BPR and HRV, the association between BPR and ultra-short-term HRV has not yet been completely described.

METHODS:

Fifteen subjects performed exercise with three different intensities on a treadmill, the speed was 6 km/h, 9 km/h, 12 km/h, respectively. SBP and DBP was measured per 30 s in each trial. The synchronous 5-min electrocardiogram (ECG) signals were recorded and HRV30s parameters including SDNN30s, RMSSD30s, SDNN30s/RMSSD30s, SD130s, SD230s and SD130s/SD230s were calculated every 30 s periods in 5 min ECG signals to match the corresponding BPR.

RESULTS:

The intraclass correlation coefficient (ICC) values and the Bland-Altman plots indicated good consistency and repeatability between HRV30s and HRV5min at three post-exercise trials, with most ICC values > 0.75. Besides, SBPR and DBPR generally decreased and returned to the Rest level in 5 mins. The Spearman correlation coefficients showed strong relationships between BPR and HRV30s sympathetic-vagal balance parameters, i.e., ratio SDNN/RMSSD and ratio SD1/SD2.

CONCLUSIONS:

These observations represented a new insight into the cardiovascular regulation at post-exercise, which could contribute to physical exercise areas in the future.

Prevalence of prehypertension and its risk factors in midlife and late life: Indonesian family life survey 2014-2015

BACKGROUND

Early detection of prehypertension is important to prevent hypertension-related complications, such as cardiovascular disease, cerebrovascular disease and all-cause mortality. Data regarding the prevalence of prehypertension among mid- and late-life population in Indonesia were lacking. It is crucial to obtain the prevalence data and identify the risk factors for prehypertension in Indonesia, which may differ from that of other countries.

METHODS

The cross-sectional analysis utilized multicenter data from Indonesian Family Life Survey-5 (IFLS-5) from 13 provinces in 2014-2015. We included all subjects at mid-and late-life (aged ≥40 years old) from IFLS-5 with complete blood pressure data and excluded those with prior diagnosis of hypertension. Prehypertension was defined as high-normal blood pressure according to International Society of Hypertension (ISH) 2020 guideline (systolic 130-139 mmHg and/or diastolic 85-89 mmHg). Sociodemographic factors, chronic medical conditions, physical activity, waist circumference and nutritional status were taken into account. Statistical analyses included bivariate and multivariate analyses.

RESULTS

There were 5874 subjects included. The prevalence of prehypertension among Indonesian adults aged > 40 years old was 32.5%. Age ≥ 60 years (adjusted OR 1.68, 95% CI 1.41-2.01, p <  0.001), male sex (adjusted OR 1.65, 95% CI 1.45-1.88, p <  0.001), overweight (adjusted OR 1.44, 95% CI 1.22-1.70, p <  0.001), obesity (adjusted OR 1.77, 95% CI 1.48-2.12, p <  0.001), and raised waist circumference (adjusted OR 1.32, 95% CI 1.11-1.56, p = 0.002) were the significant risk factors associated with prehypertension. Prehypertension was inversely associated with being underweight (adjusted OR 0.74, 95% CI 0.59-0.93, p = 0.009).

CONCLUSIONS

The prevalence of prehypertension in Indonesian mid- and late-life populations is 32.5%. Age ≥ 60 years, male sex, overweight, obesity, and raised waist circumference are risk factors for prehypertension.

Prevalence and factors associated with hypertension among people living with HIV/AIDS on antiretroviral therapy in Uganda

Introduction

antiretroviral therapy (ART) has improved survival of People Living with HIV (PLWH); however, this has resulted in an increasingly high prevalence of non-communicable diseases (NCD) like hypertension. Hypertension is a major risk factor for cardiovascular and cerebral vascular disease, which are both associated with high morbidity and mortality rates. We studied the prevalence and factors associated with hypertension among PLWH on ART.

Methods

we conducted a retrospective data analysis of PLWH on ART enrolled between 2011 and 2014 into a randomized double-blinded placebo-controlled trial investigating the safety of discontinuing cotrimoxazole prophylaxis (COSTOP) among PLWH in Central Uganda. We used the mean blood pressure (BP) measurements of the first four monthly clinic visits to define hypertension. Patients were categorised as: having normal BP (≤120/80mmHg), elevated BP (systolic >120-129, and diastolic ≤80), Stage 1 hypertension (systolic 130-139, or diastolic >80-89) and Stage 2 hypertension (systolic ≥140 or diastolic ≥90). Multiple logistic regression was used to evaluate factors associated with hypertension.

Results

data from 2026 COSTOP trial study participants were analysed, 74.1% were women and 77.2% were aged 35 years and above. The overall prevalence of hypertension was 29%, of whom 19.5% had Stage 1 hypertension and 9.5% had Stage 2 hypertension. About 21.4% were overweight or obese. Factors independently associated with hypertension among PLWH on ART included increasing age (p≤0.001) and high body mass index (p≤0.001). Efavirenz (p≤0.001) and lopinavir/ritonavir (p=0.036) based regimen had lower odds of hypertension than Nevirapine based regimens.

Conclusion

PLWH on ART have a high prevalence of hypertension, which rises with increasing age and body mass index (BMI) and among those on nevirapine-based ART. Implementation of hypertension prevention measures among PLWH on ART and integration of NCD and HIV care to improve patients’ management outcomes are required.

National trends in cardiovascular health metrics among Iranian adults using results of three cross-sectional STEPwise approaches to surveillance surveys

To examine the trends of 7 cardiovascular health metrics (CVH metrics) incorporate of smoking, physical activity, diet, body mass index (BMI), fasting plasma glucose (FPG), total cholesterol (TC), and blood pressure (BP) level during three cross-sectional STEPwise approaches to surveillance (STEPS), 2007-2016, among Iranian adults. The study population consisted of 19,841 women and 17,243 men, aged 20-65 years. The CVH metrics were categorized as 'ideal', 'intermediate', and 'poor'. The sex-stratified weighted prevalence rate of each CVH metrics was reported. The conditional probability of each poor versus combined intermediate and ideal metric was analyzed using logistic regression. In 2016 compared to 2007, the prevalence of poor BP level (20.4% vs. 23.7%), smoking (13.7% vs. 23.8%), TC ≥ 240 mg/dl (2.4% vs. 11.2%) and FPG < 100 mg/dl (75.6% vs. 82.3%) declined, whereas poor physical activity level (49.7% vs. 30%), poor healthy diet score (38.1% vs. 4.1%), BMI levels ≥ 25 kg/m2 (62.8% vs. 57.8%) increased. Despite a high prevalence of obesity among women, it remained constant in women but showed an increasing trend in men; moreover, the trends of low physical activity and current smoking were better for women. Despite some improvement in CVH metrics, < 4% of Iranian adults meet ≥ 6 CVH metrics in 2016; this issue needs intervention at the public health level using a multi-component strategy.

Age and sex specific target of blood pressure for the prevention of cardiovascular event among the treatment naive hypertensive patients

The time at which hypertension treatment should be initiated for different age groups and sexes remains controversial. We aimed to determine whether the association between blood pressure (BP) and major adverse cardiovascular events (MACE) varies with age and sex. This study enrolled 327,328 subjects who had not taken antihypertensive medication in the Korean National Health Service-National Health Screening Cohort between 2002 and 2003. Participants were categorized into four groups according to 2017 American College of Cardiology/American Heart Association hypertension guideline. Primary outcome was MACE characterized by cardiovascular mortality, myocardial infarction, unstable angina, and stroke. During a 10-year follow-up, a significant increase in MACE risk was observed from the stage 1 hypertension group (hazard ratio [HR], 1.23; 95% CI 1.15-1.32; P < 0.001) in time-varying Cox analysis. This relationship was persistent in subjects aged < 70 years, but increased MACE risk was observed only in the stage 2 hypertension group in ≥ 70 years (HR, 1.52; 95% CI 1.32-1.76, P < 0.001). When categorized as per sex, both men and women showed significant MACE risk from stage 1 hypertension. However, on comparing the sexes after stratifying by age, a significantly increased risk of MACE was shown from stage 1 hypertension in men aged < 50 years, but from stage 2 hypertension in men aged ≥ 50 years. Meanwhile, increased MACE risk was observed from stage 2 hypertension in women aged < 60 years, but from stage 1 hypertension in women aged ≥ 60 years. Thus, young male subjects had higher MACE risk than young female subjects, but this difference gradually decreased with age and there was no difference between sexes in subjects aged ≥ 70 years. Therefore, our results suggest that hypertension treatment initiation may need to be individualized depending on age and sex.

AHA/ACC-defined stage 1 hypertensive adults do not display cutaneous microvascular endothelial dysfunction

In 2017, the American Heart Association (AHA) and American College of Cardiology (ACC) redefined stage 1 hypertension to systolic blood pressure (BP) 130-139 mmHg or diastolic BP 80-89 mmHg; however, the degree to which microvascular endothelial dysfunction is evident in adults with stage 1 hypertension remains equivocal. We tested the hypotheses that cutaneous microvascular endothelial dysfunction would be present in adults with stage 1 hypertension (HTN1) compared with normotensive adults (NTN; BP <120/<80 mmHg) but would be less severe compared with adults with stage 2 hypertension (HTN2; systolic BP ≥140 mmHg or diastolic BP ≥90 mmHg) and that this graded impairment would be mediated by reductions in nitric oxide (NO)-dependent dilation. This retrospective analysis included 20 NTN (5 men; 45-64 yr; BP 94-114/60-70 mmHg), 22 HTN1 (11 men; 40-74 yr; BP 110-134/70-88 mmHg), and 44 HTN2 (27 men; 40-74 yr; BP 128-180/80-110 mmHg). BP and nocturnal dipping status were also assessed using 24-h ambulatory BP monitoring. Red cell flux (laser Doppler flowmetry) was measured during intradermal microdialysis perfusion of acetylcholine (ACh; 10^-10 to 10^-1M) alone and concurrently with the nonspecific nitric oxide (NO) synthase inhibitor N^G-nitro-l-arginine methyl ester (l-NAME; 15 mM). ACh-induced dilation was impaired in HTN2 (P < 0.01), but not in HTN1 (P = 0.85), compared with NTN. Furthermore, reductions in NO-dependent dilation were evident in HTN2 (P < 0.01) but not in HTN1 (P = 0.76). Regardless of BP, endothelium-dependent dilation was impaired in nondippers (nighttime drop in systolic BP <10%) compared with dippers (nighttime drop in systolic BP ≥10%, P < 0.05). In conclusion, functional impairments in NO-mediated endothelium-dependent dilation were not evident in HTN1. However, regardless of BP classification, the lack of a nocturnal dip in BP was associated with blunted endothelium-dependent dilation.NEW & NOTEWORTHY This is the first study to pharmacologically assess the mechanistic regulation of endothelial function in adults with hypertension, classified according to the 2017 clinical guidelines set for by the American Heart Association (AHA) and American College of Cardiology (ACC). Compared with that in normotensive adults, nitric oxide-mediated endothelium-dependent dilation is impaired in adults with stage 2, but not stage 1, hypertension. Adults lacking a nighttime dip in blood pressure demonstrated reductions in endothelium-dependent dilation.

Applying the new intensive blood pressure categories to a nondialysis chronic kidney disease population: the Prevalence, Awareness and Treatment Rates in Chronic Kidney Disease Patients with Hypertension in China survey

BACKGROUND

The 2017 high blood pressure (BP) clinical practice guideline reported by the American College of Cardiology/American Heart Association put forward new categories of BP. This study aimed to assess the applicability of the new guideline in a nondialysis chronic kidney disease (CKD) population.

METHODS

This is a nationwide, multicenter, cross-sectional study with a large sample. A total of 8927 nondialysis CKD patients in 61 tertiary hospitals in all 31 provinces, municipalities and autonomous regions of China (except Hong Kong, Macao and Taiwan) were analyzed. The categories of BP were defined as normal BP (<120/80 mmHg), elevated BP [systolic BP (SBP) 120-130 and diastolic BP (DBP) <80 mmHg], and Stage 1 (SBP 130-139 or DBP 80-89 mmHg) and Stage 2 (SBP ≥140 or DBP ≥90 mmHg) hypertension. The prevalence and control of hypertension were estimated using a new definition, and the association between the main target organs' injury and new categories of BP was analyzed.

RESULTS

The prevalence, awareness and treatment of hypertension in nondialysis CKD patients were 79.8, 72.4 and 68.3%, respectively. Approximately 11.9% had BP <130/80 mmHg and 6.6% had BP <120/80 mmHg. Subgroups by categories of BP had significant differences in age, sex, body mass index category, primary cause and CKD stage (P < 0.001). After multivariable adjustment, only Stage 2 hypertension was associated with decreased renal function [odds ratio (OR) 2.4, 95% confidence interval (CI) 1.9-3.0, P < 0.001], cardiovascular disease (OR 2.0, 95% CI 1.3-3.1, P = 0.001) and cerebrovascular disease (OR 2.7, 95% CI 1.2-5.8, P = 0.015).

CONCLUSIONS

Using the new definition of hypertension, the higher prevalence and lower control of hypertension were shown in nondialysis CKD participants. More studies are necessary to confirm the applicability of new categories of BP in CKD population because only Stage 2 hypertension showed statistical association with the main target organs' injury.

Prehypertension and risk of cardiovascular diseases: a meta-analysis of 47 cohort studies

OBJECTIVE

To assess the association of prehypertension (SBP 120-139 mmHg and/or DBP 80-89 mmHg) and total cardiovascular diseases (CVDs), coronary heart disease (CHD), myocardial infarction (MI), and stroke.

METHODS

PubMed, Embase, and Web of Science were searched for articles published up to 7 November 2018. Normal range BP was considered SBP less than 120 mmHg and DBP less than 80 mmHg. RRs and 95% CIs were pooled using fixed-effects models. Meta-regression was conducted to estimate the heterogeneity among subgroups.

RESULTS

We included 27 articles (47 studies including 491 666 study participants) in the analysis. Prehypertension was associated with total CVDs (RR 1.40, 95% CI 1.34-1.46), CHD (1.40, 1.28-1.52), MI (1.86, 1.50-2.32), and stroke (1.66, 1.56-1.76). Risk of total CVDs, MI, and stroke was increased with low-range prehypertension (low-range: SBP 120-129 mmHg and/or DBP 80-84 mmHg) versus normal BP - RR 1.42 (95% CI 1.29-1.55), 1.43 (1.10-1.86), and 1.52 (1.27-1.81), respectively - and risk of total CVDs, CHD, MI, and stroke was increased with high-range prehypertension (high-range: SBP 130-139 mmHg and/or DBP 85-89 mmHg) - RR 1.81 (95% CI 1.56-2.10), 1.65 (1.13-2.39), 1.99 (1.59-2.50), and 1.99 (1.68-2.36), respectively. The population-attributable risk for the association of total CVDs, CHD, MI, and stroke with prehypertension was 12.09, 13.26, 24.60, and 19.15%, respectively.

CONCLUSION

Prehypertension, particularly high-range, is associated with increased risk of total CVDs, CHD, MI, and stroke. Effective control of prehypertension could prevent more than 10% of CVD cases.

Outcomes in adults with systolic blood pressure between 130 and 139 mmHg in Action to Control Cardiovascular Risk in Diabetes Blood Pressure trial and Systolic Blood Pressure Intervention Trial

BACKGROUND

Patients with stage 1 systolic hypertension have increased risk of cardiovascular disease (CVD) events.

METHODS

Using Cox models, we assess the effect of targeting an intensive SBP goal of less than 120 mmHg compared with standard SBP goal of less than 140 mmHg on the risk of CVD events in adults with stage 1 systolic hypertension with diabetes mellitus enrolled in Action to Control Cardiovascular Risk in Diabetes Blood Pressure trial (ACCORD BP) (n = 1901) and without diabetes mellitus enrolled in Systolic Blood Pressure Intervention Trial (SPRINT) (n = 3484) that used identical SBP goal interventions.

OUTCOMES

In ACCORD BP, the primary composite CVD outcome was the first occurrence of myocardial infarction, stroke, or CVD mortality. In SPRINT, the primary composite CVD outcome was the first occurrence of myocardial infarction, other acute coronary syndrome, stroke, heart failure, or CVD mortality.

RESULTS

In SPRINT, targeting an intensive SBP goal significantly reduced the risk of the primary CVD outcome [hazard ratio 0.75 (95% confidence interval, 0.58-0.98); events 1.78 vs. 2.37%/year]. In ACCORD BP, the relationships of SBP goal with the primary CVD outcome was modified by the glycemia goal intervention (interaction P = 0.039). In the standard glycemia subgroup (A1c target 7-7.9%), intensive SBP goal significantly reduced the risk of the primary CVD outcome [hazard ratio 0.61 (0.40-0.94); events 1.63 vs. 2.56%/year]. In the intensive glycemia subgroup (A1c target <6%), the risk of the primary CVD outcome was not significantly different between groups [hazard ratio 1.20 (0.76-1.89); events 1.91 vs. 1.60%/year].

CONCLUSION

Targeting an intensive SBP goal significantly reduced the risk of CVD events in patients with stage 1 systolic hypertension without diabetes and with diabetes on standard glycemia goal.

The global epidemiology of hypertension

Hypertension is the leading cause of cardiovascular disease and premature death worldwide. Owing to the widespread use of antihypertensive medications, global mean blood pressure (BP) has remained constant or has decreased slightly over the past four decades. By contrast, the prevalence of hypertension has increased, especially in low- and middle-income countries (LMICs). Estimates suggest that 31.1% of adults (1.39 billion) worldwide had hypertension in 2010. The prevalence of hypertension among adults was higher in LMICs (31.5%, 1.04 billion people) than in high-income countries (28.5%, 349 million people). Variations in the levels of risk factors for hypertension, such as high sodium intake, low potassium intake, obesity, alcohol consumption, physical inactivity and unhealthy diet, may explain some of the regional heterogeneity in hypertension prevalence. Despite the increasing prevalence, the proportions of hypertension awareness, treatment and BP control are low, particularly in LMICs, and few comprehensive assessments of the economic impact of hypertension exist. Future studies are warranted to test implementation strategies for hypertension prevention and control, especially in low-income populations, and to accurately assess the prevalence and financial burden of hypertension worldwide.

Antihypertensive phytocomplexes of proven efficacy and well-established use: Mode of action and individual characterization of the active constituents

Hypertension has become the leading risk factor for worldwide cardiovascular diseases. Conventional pharmacological treatment, after both dietary and lifestyle changes, is generally proposed. In this review, we present the antihypertensive properties of phytocomplexes from thirteen plants, long ago widely employed in ethnomedicines and, in recent years, increasingly evaluated for their activity in vitro and in vivo, also in humans, in comparison with synthetic drugs acting on the same systems. Here, we focus on the demonstrated or proposed mechanisms of action of such phytocomplexes and of their constituents proven to exert cardiovascular effects. Almost seventy phytochemicals are described and scientifically sound pertinent literature, published up to now, is summarized. The review emphasizes the therapeutic potential of these natural substances in the treatment of the 'high normal blood pressure' or 'stage 1 hypertension', so-named according to the most recent European and U.S. guidelines, and as a supplementation in more advanced stages of hypertension, however needing further validation by clinical trial intensification.

Lower Systolic Blood Pressure in Normotensive Subjects is Related to Better Autonomic Recovery Following Exercise

Blood pressure (BP) is a cardiovascular parameter applied to detect cardiovascular risk. Recently, the pre-hypertension state has received greater consideration for prevention strategies. We evaluated autonomic and cardiorespiratory recovery following aerobic exercise in normotensive individuals with different systolic BP (SBP) values. We investigated 30 healthy men aged 18 to 30 years divided into groups according to systolic BP (SBP): G1 (n = 16), resting SBP <110 mmHg and G2 (n = 14), resting SBP between 120-110 mmHg. The groups endured 15 minutes seated at rest, followed by a submaximal aerobic exercise on a treadmill and then remaining seated for 60 minutes also at rest, during recovery from the exercise. Cardiorespiratory parameters and heart rate (HR) variability (HRV) (rMSSD, SD1, HF [ms2]) were evaluated before and during recovery from exercise. G2 displayed slower return of SBP, rMSSD and SD1 HRV indices during recovery from exercise compared to G1. In conclusion, normotensive subjects with higher resting SBP (110 to 120 mmHg) offered delayed autonomic recovery following moderate exercise. We suggest that this group may be less physiologically optimized leading to cardiac risks.

Intracranial Atherosclerosis and Stage 1 Hypertension Defined by the 2017 ACC/AHA Guideline

BACKGROUND

In 2017, the American College of Cardiology (ACC)/American Heart Association (AHA) released a new, stricter definition of stage 1 hypertension which was previously considered prehypertension. However, impacts of the novel stage 1 hypertension on deleterious target-organ outcomes are still controversial. In this study, we evaluated the relationship between this newly defined stage 1 hypertension and the presence of intracranial atherosclerosis (ICAS) lesions in neurologically healthy participants.

METHODS

We assessed consecutive participants in routine health checkups between January 2006 and December 2013. Blood pressure (BP) was classified according to the 2017 ACC/AHA hypertension guideline, and ICAS was defined as occlusion or ≥50% stenosis of intracranial vessels on flight magnetic resonance angiography.

RESULTS

Among 3,111 healthy participants (mean age: 56 years, sex: 54% men), 85 (3%) had ICAS lesions. In multivariate analysis, stage 1 hypertension (adjusted odds ratio: 2.46, 95% confidence interval: 1.10-5.51, P = 0.029) remained an independent predictor of ICAS after adjustment for confounders. Stage 2 hypertension showed a higher odds ratio and a lower P value, indicating a dose-response effect. Age and HbA1c level were also significantly associated with ICAS, independent of the BP categories. The ICAS lesion burden showed a dose-response effect across the BP categories (P for trend <0.001), whereas ICAS lesion location did not (P for trend = 0.699).

CONCLUSIONS

We demonstrated that stage 1 hypertension, defined according to the 2017 ACC/AHA guideline, was associated with a higher prevalence and burden of ICAS lesions in a neurologically healthy population.

Pregnancy outcomes among women with American College of Cardiology- American Heart Association defined hypertension

Objective: To compare the rate of adverse pregnancy outcomes of women with hypertension defined by the ACC-AHA guidelines, women with hypertension defined by ACOG guidelines, and normotensive women.Methods: A historical cohort study of women with singleton, nonanomalous pregnancies who presented before 20 weeks for their first prenatal visit between 1 January 2014 and 31 January 2016 with (a) hypertension defined by ACC-AHA (systolic blood pressure 130 mmHg and/or diastolic blood pressure of 80 mmHg documented), (b) hypertension defined by ACOG (systolic blood pressure of 140 mmHg and/or diastolic blood pressure of 90 mmHg documented) and (c) women documented to be normotensive. Primary outcomes were preeclampsia and small for gestational age. Fisher's exact test was used to compare demographics and risk factors between the groups. Multivariable logistic regression analysis was used to predict the association of preeclampsia within the groups adjusting for additional risk factors.Results: A total of 252 women were included. Of these, 92 (36.5%) had hypertension by ACC-AHA, 34 (13.5%) by ACOG and 126 (50%) were normotensive. Sixty percent of women with the ACOG definition developed preeclampsia compared to 45.1% of women with the ACC-AHA definition and 17.1% in the control group (p < .001). The rate of preeclampsia among women with hypertension by ACC-AHA criteria was not significantly different from the rate among women with hypertension by ACOG criteria (p = .288). Differences in small for gestational age among the groups were not significant (ACOG: 20%, ACC-AHA: 11.1%, normotensive: 9.8%, p = .423).Conclusion: Women with hypertension defined by ACC-AHA have a rate of developing preeclampsia that is similar to that of women with hypertension defined by ACOG.

Blood pressure in pregnancy-A stress test for hypertension? Five-year, prospective, follow-up of the ROLO study

OBJECTIVE

To investigate whether maternal blood pressure (BP) below the diagnostic criteria of hypertensive disorders of pregnancy (HDP) is associated with maternal BP 5 years later.

DESIGN

Prospective, observational study.

SETTING

Dublin, Ireland (2007-2011).

SAMPLE

Three hundred twenty-nine women from the ROLO study (Randomized cOntrol trial of LOw glycaemic index diet to prevent the recurrence of macrosomia).

METHODS

Maternal BP measurements were taken during pregnancy (13, 28 and 34 weeks' gestation and day 1 postpartum) and at the 5-year follow-up. Systolic BP (SBP) and diastolic BP (DBP) were categorized as normal (SBP < 120 and DBP < 80 mm Hg), elevated (SBP 120-129 and DBP < 80 mm Hg), HTN stage 1 (SBP 130-139 or DBP 80-89 mm Hg) or HTN stage 2 (SBP ≥ 140 or DBP ≥ 90 mm Hg) at each timepoint.

MAIN OUTCOME MEASURES

Maternal blood pressure at the 5-year follow-up.

RESULTS

Women with elevated BP at 28 and 34 weeks' gestation had 2.68 (95% CI: 1.36-5.26) and 2.45-fold (95% CI: 1.22-4.95) increased odds of HTN stage 1 respectively, at the 5-year follow-up, compared to those with normal BP in pregnancy.

CONCLUSION

Elevated BP at 28 and 34 weeks' gestation was associated with an increased risk of HTN stage 1 at 5 years later. Thus, raised BP, below the diagnostic criteria of HDP, could be flagged for follow-up postpartum.

Cerebral Small Vessel Disease and Stage 1 Hypertension Defined by the 2017 American College of Cardiology/American Heart Association Guidelines

Although the American College of Cardiology/American Heart Association guidelines have introduced a novel definition of hypertension in their 2017 hypertension guidelines, the influence of novel stage 1 hypertension on cerebrovascular diseases remains unclear. In this study, we evaluated the relationship between stage 1 hypertension, as defined by the 2017 American College of Cardiology/American Heart Association guidelines and cerebral small vessel disease in a healthy population. We assessed consecutive health checkup participants without the use of antihypertensive medication between 2006 and 2013. White matter hyperintensity volumes were rated using semiautomated quantitative methods. The presence of lacunes, cerebral microbleeds, and enlarged perivascular spaces was also measured as cerebral small vessel disease lesions. We classified the blood pressure of all participants according to the 2017 American College of Cardiology/American Heart Association guidelines. A total of 2460 participants were evaluated. In adjusted linear and logistic regression analyses, stage 1 hypertension was independently associated with white matter hyperintensity volume (β=0.158; 95% CI, 0.046-0.269; P=0.006), presence of lacune (adjusted odds ratio, 1.66; 95% CI, 1.00-2.73; P=0.048), and deep cerebral microbleeds (adjusted odds ratio, 2.50, 95% CI, 1.08-5.79; P=0.033). Stage 2 hypertension showed higher coefficients or adjusted odds ratio values and lower P values in all analyses of white matter hyperintensity volumes, lacunes, and deep cerebral microbleeds, indicating dose-response effects across blood pressure categories. Stage 1 hypertension according to the 2017 American College of Cardiology/American Heart Association guidelines is associated with cerebral small vessel disease lesions, especially in white matter hyperintensity lesions, lacunes, and deep cerebral microbleeds.

2017 ACC/AHA Blood Pressure Classification and Cardiovascular Disease in 15 Million Adults of Age 20-94 Years

The 2017 American College of Cardiology/American Heart Association (ACC/AHA) high blood pressure (BP) guideline lowered the cut-off for hypertension, but its age-specific association with cardiovascular disease (CVD) remains inconclusive in different populations. We evaluated the association between high BP according to the 2017 ACC/AHA guideline and CVD risks in Koreans aged 20-94 years. In a nationwide health screening cohort, we included 15,508,537 persons aged 20-94 years without prior CVD. BP was categorized into normal, elevated, stage 1 hypertension, or stage 2 hypertension. The primary outcome was a composite CVD hospitalization (myocardial infarction, stroke, and/or heart failure). Over 10 years of follow-up, CVD incidence rates per 100,000 person-years were 105.4, 168.3, 215.9, and 641.2 for normal, elevated BP, stage 1, and stage 2 hypertension, respectively. The age-specific hazard ratios of stage 1 hypertension compared to normal BP were 1.41 (1.34-1.48) at ages 20-34, 1.54 (1.51-1.57) at ages 35-49, 1.38 (1.35-1.40) at ages 50-64, 1.21 (1.19-1.24) at ages 65-79, and 1.11 (1.03-1.19) at ages 80-94 years. With the lowered BP cut-off, 130/80 mmHg, population attributable fraction for CVD was 32.2%. In conclusion, stage 1 hypertension was significantly associated with a higher CVD risk across entire adulthood. The new definition of hypertension may have a substantial population impact on primary CVD prevention.

Impact of new hypertension guidelines on target organ damage screening in a Shanghai community-dwelling population

Recently, the 2017 ACC/AHA released new hypertension guidelines and proposed a redefinition of hypertension from 140/90 to 130/80 mm Hg. This study assesses the impact of the lower threshold for hypertension diagnosis on the association of hypertension with target organ damage (TOD). Health checks were conducted in a community-dwelling population in Shanghai in 2017 (N = 10 826; 43.26% mean, age 62 ± 12 years [range 29-95 years]). Subclinical TOD indices were quantified in terms of left ventricular hypertrophy (LVH) by electrocardiogram (Sokolow-Lyon standard), estimated glomerular filtration rate (eGFR), and presence of proteinuria. Information on clinical TOD was obtained by questionnaire. Arteriosclerotic cardiovascular disease (ASCVD) was determined by the 2013 ACC/ AHA recommended guidelines. Compared to the higher threshold (140/90 mm Hg), the lower threshold (130/80 mm Hg) was associated with variable rates of increased detection of hypertension and TOD: (a) Hypertension: incidence of hypertension, 29.5% (51.8%-81.5%) increase in persons with hypertension if the threshold of 130/80 mm Hg is used; (b) Subclinical TOD: LVH, 20.8%; eGFR (30-60 mL/min per 1.73 m² ), 23.7%; proteinuria, 23.5%; (c) Clinical TOD: chronic kidney disease (CKD) IV (eGFR＜30 mL/min per 1.73 m² ), 3.1%; diabetes (fasting glucose ≥7.0 mmol/L or HbA1C＞7.0%), 24.3%; stroke, 26.4%; chronic heart disease, 28.1%; acute myocardial infarction, 19.5% (69.4% to 88.9% of total of 36); ASCVD ≥10%, 29.3%. The lower threshold was associated with a significantly higher detection rate of clinical and subclinical TOD of approximately 20% compared to the higher threshold. 15%-20% of TOD and 29% of ASCVD were also found below the lower threshold of hypertension.

Comparison of the 2017 ACC/AHA Hypertension Guideline with Earlier Guidelines on Estimated Reductions in Cardiovascular Disease

PURPOSE OF REVIEW

To review the recommendations of the 2017 American College of Cardiology/American Heart Association hypertension guideline and to compare it with previous guidelines on potential cardiovascular disease (CVD) and mortality risk reductions.

RECENT FINDINGS

Compared with previous guidelines, the 2017 hypertension guideline increased the prevalence of hypertension and the number of adults recommended for antihypertensive therapy in the US population. Based on data from recent analyses, the new guideline effectively directs antihypertensive therapy toward individuals at higher CVD risk. Two recent analyses using US national data estimated that implementation of the 2017 hypertension guideline could further reduce hundreds of thousands of CVD events and deaths compared with previous guidelines. However, the new guideline might increase the number of adverse events. The new guideline also improves the number of individuals needed to treat to prevent CVD events and deaths, suggesting implementation is cost-effective. Implementation of the 2017 hypertension guideline is projected to substantially reduce CVD events and deaths in the USA but might increase the number of adverse events. Future research is needed to implement and scale up effective, equitable, and sustainable strategies for applying the new guideline in daily clinical practice.

Associations between body mass index, waist circumference, waist-to-height ratio, and high blood pressure among adolescents: a cross-sectional study

The purpose of the present study was to examine the associations between body mass index (BMI), waist circumference (WC), waist-to-height ratio (WHtR), and high blood pressure (HBP), and to determine which anthropometric parameters can best predict HBP among Lithuanian adolescents aged 12–15 years. Data from the survey of “Prevalence and Risk Factors of HBP in 12–15-Year-Old Lithuanian Children and Adolescents (Study 1, 2010–2012)” were used; a total of 7,457 respondents (3,494 boys and 3,963 girls) were included in this analysis. Adolescents with BP above the 90th percentile were measured on two different occasions. Logistic regression analysis was used to assess the associations and to calculate odds ratios. Receiver operating characteristic (ROC) curve analysis was used to evaluate the predictive ability of the three anthropometric parameters to predict HBP. The adjusted odds ratios (aOR) in the highest quartiles of BMI, WC, and WHtR were statistically significant for both sexes separately (reference group – the first quartile): in boys, prehypertension – 4.91, 4.09, and 1.59; hypertension – 7.96, 6.44, and 2.81; and prehypertension/hypertension – 6.85, 5.65, and 2.37, respectively; and in girls, prehypertension – 3.42, 2.70, and 1.66; hypertension – 5.71, 3.54, and 2.90; and prehypertension/hypertension – 4.62, 3.17, and 2.31, respectively). According to the analyses of the ROC curve, BMI z-score provided the largest area under the curve (AUC) value, followed by WC z-score, while WHtR z-score showed the lowest AUC value in predicting elevated BP in both sexes separately. Among Lithuanian adolescents aged 12–15 years, both anthropometric indices – BMI and WC (but particularly BMI) – showed stronger associations with HBP and were better for the prediction of HBP, compared to WHtR.

Agreement between 2017 ACC/AHA Hypertension Clinical Practice Guidelines and Seventh Report of the Joint National Committee Guidelines to Estimate Prevalence of Postmenopausal Hypertension in a Rural Area of Bangladesh: A Cross Sectional Study

Background and objectives: Justification for application of 2017 American College of Cardiology/American Heart Association (ACC/AHA) guidelines to detect hypertension (HTN) among Bangladeshi population is understudied. This prompted us to examine the level of agreement between 2017 ACC/AHA and Joint National Committee 7 (JNC 7) guidelines to detect postmenopausal HTN in a rural area of Bangladesh. Materials and Methods: This cross-sectional study recruited 265 postmenopausal women of 40-70 years of age who visited a rural primary health care centre of Bangladesh. HTN was diagnosed based on two definitions: the JNC 7 guidelines (SBP ≥ 140 or DBP ≥ 90 mmHg), and the 2017 ACC/AHA guidelines (SBP ≥ 130 mmHg, or DBP ≥ 80 mmHg). The prevalence of postmenopausal HTN, its sub-types and stages were reported and compared using frequency and percentage. Agreement was evaluated using Cohen's Kappa (κ), Prevalence-Adjusted Bias-Adjusted Kappa (PABAK) and First-order Agreement Coefficient (AC1). Results: The prevalence of postmenopausal HTN was 67.5% and 41.9% using 2017 ACC/AHA and JNC 7 guidelines respectively. Among the HTN sub-types and stages, the new 2017 ACC/AHA guideline classified higher proportion of respondents as having isolated systolic hypertension (ISH) (42.6%) and stage 2 HTN (35.8%) compared to JNC 7 (28.7% and 6.8% respectively). On the other hand, the JNC 7 guideline identified more respondents as pre-hypertensive (32.5%) when compared with the 2017 ACC/AHA guideline (3.8%). Between two guidelines, highest agreement was observed for ISH (86.03%) and those had pre-hypertension/elevated blood pressure (71.3%). Similarly, Landis & Koch's approach detected highest agreement for ISH (κ = 0.74, substantial; PABAK = 0.76, substantial; AC1 = 0.84, excellent; p < 0.001) and pre-hypertension/elevated blood pressure (κ= 0.12, slight; PABAK = 0.42, moderate; AC1 = 0.83, excellent; p < 0.001). Conclusions: The 2017 ACC/AHA HTN guideline reported high agreement and detected more participants as hypertensive when compared with JNC 7 guideline for Bangladeshi postmenopausal women that demands further large-scale study in general population to clarify the current findings more precisely.
