Blood pressure variability: clinical relevance and application

Abstract: Blood pressure variability is an entity that characterizes the continuous and dynamic fluctuations that occur in blood pressure levels throughout a lifetime. This phenomenon has a complex and yet not fully understood physiological background and can be evaluated over time spans ranging from seconds to years. The present paper provides a short overview of methodological aspects, clinical relevance, and potential therapeutic interventions related to the management of blood pressure variability.

Subjective sleep quality, blood pressure, and hypertension: a meta-analysis

Abstract: Sleep quality is an important aspect of sleep, but no meta-analysis has elucidated its relationship with blood pressure (BP) and hypertension. A meta-analysis was conducted in October 2016 using multiple databases, including Embase and Medline. Studies that assessed subjective sleep quality and BP or hypertension were included. Upon full-text evaluation, 29 articles from 45 041 patients were selected, of which 22 articles were included in the meta-analysis and seven were presented narratively. Poor sleep quality was significantly associated with a greater likelihood of hypertension (odds ratio, 1.48; P value = .01). Poor sleepers had higher average systolic BP (mean difference = 4.37, P value = .09) and diastolic BP (mean difference = 1.25, P value = .32) than normal sleepers without statistical significance. Patients with hypertension had significantly worse sleep quality scores (mean difference = 1.51, P value < .01), while BP dippers had significantly better scores (mean difference = -1.67, P value < .01). The findings highlight the relationship between sleep quality and hypertension.

High sodium intake increases blood pressure and risk of kidney disease. From the Science of Salt: A regularly updated systematic review of salt and health outcomes (August 2016 to March 2017).

Abstract: The purpose of this review was to identify, summarize, and critically appraise studies on dietary salt and health outcomes that were published from August 2016 to March 2017. The search strategy was adapted from a previous systematic review on dietary salt and health. Studies that meet standards for methodological quality criteria and eligible health outcomes are reported in detailed critical appraisals. Overall, 47 studies were identified and are summarized in this review. Two studies assessed all-cause or disease-specific mortality outcomes, eight studies assessed morbidity reduction-related outcomes, three studies assessed outcomes related to symptoms/quality of life/functional status, 25 studies assessed blood pressure (BP) outcomes and other clinically relevant surrogate outcomes, and nine studies assessed physiologic surrogate outcomes. Eight of these studies met the criteria for outcomes and methodological quality and underwent detailed critical appraisals and commentary. Five of these studies found adverse effects of salt intake on health outcomes (BP; death due to kidney disease and initiation of dialysis; total kidney volume and composite of kidney function; composite of cardiovascular disease (CVD) events including, and risk of mortality); one study reported the benefits of salt restriction in chronic BP and two studies reported neutral results (BP and risk of CKD). Overall, these articles confirm the negative effects of excessive sodium intake on health outcomes.

Home blood pressure monitoring in the 21st century.

Abstract: Home blood pressure monitoring provides multiple measurements in the usual environment of each individual, allows the detection of intermediate hypertension phenotypes (white-coat and masked hypertension), and appears to have superior prognostic value compared to the conventional office blood pressure measurements Accumulating evidence suggests that home blood pressure monitoring improves long-term hypertension control rates Moreover, it is widely available, relatively inexpensive, and well accepted by patients Thus, current guidelines recommend home blood pressure monitoring as an essential method for the evaluation of almost all untreated and treated patients with suspected or treated hypertension Validated automated upper-arm cuff devices with automated storage and averaging of readings should be used The home blood pressure monitoring schedule for 4 to 7 days with exclusion of the first day (12-24 readings) should be averaged to provide values for decision making

Validation protocols for blood pressure measuring devices in the 21st century.

Abstract: Blood pressure (BP) is a vital sign and the essential measurement for the diagnosis of hypertension. Therefore, its accurate measurement is a key element for the evaluation of many medical conditions and for the reliable diagnosis and efficient treatment of hypertension. In the last 3 decades prestigious organizations, such as the US Association for the Advancement of Medical Instrumentation (AAMI), the British Hypertension Society, the European Society of Hypertension (ESH) Working Group on BP Monitoring, and the International Organization for Standardization (ISO), have developed protocols for clinical validation of BP measuring devices. All these initiatives aim to standardize validation procedures and establish minimum accuracy standards for BP monitors. Unfortunately, only a few of the BP measuring devices available on the market have been subjected to independent validation using one of these protocols. Recently, the AAMI, ESH, and ISO experts agreed to develop a single universally acceptable standard (AAMI/ESH/ISO), which will replace all previous protocols. This major international initiative has been undertaken to best serve the needs of patients with hypertension, a public interested in cardiovascular health, practicing physicians, scientific researchers, regulatory bodies, and manufacturers. There is an urgent need to influence regulatory authorities throughout the world to make it mandatory for all BP measuring devices to have undergone independent validation before approval for marketing. Efforts need to be intensified to improve the accuracy of BP measuring devices, further optimize the validation procedure, and ensure that objective and unbiased validation data become available.

Morning surge in blood pressure and blood pressure variability in Asia: Evidence and statement from the HOPE Asia Network

Abstract: Hypertension is a major risk factor for cardiovascular and cerebrovascular diseases. To effectively prevent end-organ damage, maintain vascular integrity and reduce morbidity and mortality, it is essential to decrease and adequately control blood pressure (BP) throughout each 24-hour period. Exaggerated early morning BP surge (EMBS) is one component of BP variability (BPV), and has been associated with an increased risk of stroke and cardiovascular events, independently of 24-hour average BP. BPV includes circadian, short-term and long-term components, and can best be documented using out-of-office techniques such as ambulatory and/or home BP monitoring. There is a large body of evidence linking both BPV and EMBS with increased rates of adverse cardio- and cerebrovascular events, and end-organ damage. Differences in hypertension and related cardiovascular disease rates have been reported between Western and Asian populations, including a higher rate of stroke, higher prevalence of metabolic syndrome, greater salt sensitivity and more common high morning and nocturnal BP readings in Asians. This highlights a need for BP management strategies that take into account ethnic differences. In general, long-acting antihypertensives that control BP throughout the 24-hour period are preferred; amlodipine and telmisartan have been shown to control EMBS more effectively than valsartan. Home and ambulatory BP monitoring should form an essential part of hypertension management, with individualized pharmacotherapy to achieve optimal 24-hour BP control particularly the EMBS and provide the best cardio- and cerebrovascular protection. Future research should facilitate better understanding of BPV, allowing optimization of strategies for the detection and treatment of hypertension to reduce adverse outcomes.

Visit-to-visit variability in blood pressure and Alzheimer's disease.

Abstract: Alzheimer's disease is the most common type of dementia and one of the leading sources of disability and dependency in the elderly. Given the limited treatment options, understanding the role of modifiable risk factors implied in the disease pathogenesis is a worthwhile endeavor to limit its global burden. Recently, the variability of blood pressure has been suggested to be a significant determinant of brain alterations and a potential therapeutic target. The aim of this article is to review the clinical evidence on the association between visit-to-visit blood pressure variability and Alzheimer's disease, highlight the underlying mechanisms, and suggest future implications.

Twenty-Four-Hour Diet recall and Diet records compared with 24-hour urinary excretion to predict an individual's sodium consumption: A Systematic Review.

Abstract: This systematic literature review aimed to investigate whether 24 hour diet recall and diet records are reliable and valid ways to measure usual dietary sodium intake compared with 24 hour urinary assessment. We searched electronic databases Medline, Embase, Cinahl, Lilacs, Google Scholar and the Cochrane Library using pre-defined terms Studies were eligible for inclusion if they assessed adult humans in free-living settings, and if they included dietary assessment and 24 hours urinary collection for assessment of sodium intake in the same participants. Studies that included populations with an active disease state that might interfere with normal sodium metabolism were excluded. Results of 20 studies using 24 hour diet recall recall (including 14 validation studies) and 10 studies using food records (including six validation studies) are included in this review. Correlations between estimates from dietary assessment and urinary excretion ranged from 0.16 to 0.72 for 24 hour diet recall, and 0.11 to 0.49 for food diaries. Bland-Altman analysis in two studies of 24 hour diet recall showed poor agreement with 24 hours urinary sodium excretion. These results show that 24 hour diet recall and diet records inaccurately measure dietary sodium intake in individuals compared with the gold standard 24 hours urinary excretion. Validation studies of dietary assessment methods should include multiple days of assessment and 24 hours urine collection, use relevant food composition databases and Bland-Altman methods of analysis.

Hypertension and frailty in older adults.

Abstract: The association between hypertension and frailty syndrome in older adults remains unclear. There is scarce information about the prevalence of hypertension among frail elderly patients or on its relationship with frailty. Up to one quarter of frail elderly patients present without comorbidity or disability, yet frailty is a leading cause of death. The knowledge and better control of frailty risk factors could influence prognosis. The present study evaluated: (1) the prevalence of hypertension in robust, prefrail, and frail elderly; and (2) factors that might be associated with frailty including hypertension. A cross-sectional study was conducted in 619 older adults at a university-based outpatient center. Study protocol included sociodemographic data, measures of blood pressure and body mass index, frailty screening according to the internationally validated FRAIL (fatigue, resistance, ambulation, illnesses, and loss of weight) scale, number of comorbidities, drug use assessment, physical activity, cognitive status, and activities of daily living. Ordinal logistic regression was used to evaluate factors associated with frailty. Prevalence of hypertension and frailty was 67.3% and 14.8%, respectively, in the total sample. Hypertension was more prevalent in the prefrail (72.5%) and frail (83%) groups than among controls (51.7%). Hypertension, physical activity, number of prescribed drugs, and cognitive performance were significantly associated with frailty status. Hypertension presented an odds ratio of 1.77 towards frailty (95% confidence interval, 1.21-2.60; P = .002). Hypertension was more prevalent in frail elderly patients and was significantly associated with frailty. Intensive control of hypertension could influence the trajectory of frailty, and this hypothesis should be explored in future prospective clinical trials.

Association of impaired endothelial glycocalyx with arterial stiffness, coronary microcirculatory dysfunction, and abnormal myocardial deformation in untreated hypertensives

Abstract: We investigated the association of endothelial glycocalyx damage with arterial stiffness, impairment of coronary microcirculatory function, and LV myocardial deformation in 320 untreated hypertensives and 160 controls. We measured perfused boundary region (PBR) of the sublingual microvessels, a marker inversely related with glycocalyx thickness, coronary flow reserve (CFR), and Global Longitudinal strain (GLS) by echocardiography, pulse wave velocity (PWV), and central systolic blood pressure (cSBP). Hypertensives had higher PBR, PWV cSBP, and lower CFR and GLS than controls (P < .05). In hypertensives, increased PBR was associated with increased cSBP, PWV, and decreased CFR and GLS after adjustment for age, sex, BMI, smoking LV mass, heart rate, hyperlipidemia, and office SBP (P < .05). PBR had an additive value to PWV, CFR, and office SBP for the prediction of abnormal GLS (x2 = 2.4-3.8, P for change = .03). Endothelial glycocalyx is impaired in untreated hypertensives and is related to arterial stiffness, coronary, and myocardial dysfunction.

Guidance on home blood pressure monitoring: A statement of the HOPE Asia Network

Abstract: Hypertension is an important modifiable cardiovascular risk factor and a leading cause of death throughout Asia. Effective prevention and control of hypertension in the region remain a significant challenge despite the availability of several regional and international guidelines. Out-of-office measurement of blood pressure (BP), including home BP monitoring (HBPM), is an important hypertension management tool. Home BP is better than office BP for predicting cardiovascular risk and HBPM should be considered for all patients with office BP ≥ 130/85 mm Hg. It is important that HBPM is undertaken using a validated device and patients are educated about how to perform HBPM correctly. During antihypertensive therapy, monitoring of home BP control and variability is essential, especially in the morning. This is because HBPM can facilitate the choice of individualized optimal therapy. The evidence and practice points in this document are based on the Hypertension Cardiovascular Outcome Prevention and Evidence (HOPE) Asia Network expert panel consensus recommendations for HBPM in Asia.

Potential need for expanded pharmacologic treatment and lifestyle modification services under the 2017 ACC/AHA Hypertension Guideline

Abstract: Application of the 2017 ACC/AHA Hypertension Guideline expands the number of US adults requiring blood pressure (BP) management. The authors use 2011-2014 NHANES data to describe the population groups most affected by the new guideline, compared with the previous JNC-7 guideline, and describe the previous interaction with the health care sector among those adults recommended new or intensified pharmacologic treatment and/or lifestyle modification. The 2017 Hypertension Guideline reclassifies 32.3 million US adults as newly hypertensive and recommends BP-related treatment of 133.7 million adults, including 57.8 million with uncontrolled BP recommended to initiate or intensify pharmacologic treatment and 50.5 million newly recommended lifestyle modification alone. An estimated 13.1 million (22.7%) adults recommended to initiate or intensify pharmacologic treatment, and 20.6 million (40.8%) adults newly recommended lifestyle modification alone report not having established health care linkages. Among the adults newly recommended lifestyle modification alone, the odds of reclassification from no recommended intervention, under JNC-7, to recommended lifestyle modification alone were lower for adults with established linkages to care (aOR: 0.78 [95% CI: 0.67-0.91]) compared to those without, decreased with increasing age, were greater for men (1.72 [1.52-1.94]) compared to women and were greater for obese adults (1.23 [1.00-1.53]) compared with normal or underweight adults. Application of the 2017 Hypertension Guideline increases the number and alters the distribution of US adults in need of initiating or intensifying BP treatment. This includes identifying millions of US adults who previously had limited interaction with health care and are now recommended new or intensified pharmacologic treatment and/or lifestyle modification.

Home blood pressure telemonitoring in the 21st century.

Abstract: Blood pressure telemonitoring (BPT) is a telehealth strategy that allows remote data transmission of blood pressure and additional information on patients' health status from their dwellings or from a community setting to the doctor's office or the hospital There is sufficiently strong evidence from several randomized controlled trials that the regular and prolonged use of BPT combined with telecounseling and case management under the supervision of a team of healthcare professionals is associated with a significant blood pressure reduction compared with usual care, particularly in cases of patients at high risk However, most current evidence is based on studies of relatively short duration (<12 months), and in the few studies that have investigated longer-term outcomes, no evidence of better or sustained effect could be provided In addition, no definition of the optimal BPT-based healthcare delivery model could be derived from the studies performed so far, because of the heterogeneity of interventions, technologies, and study designs BPT can also be provided in the context of "mobile health" (m-health) wireless solutions, together with educational support, medication reminders, and teleconsultation When BPT is integrated in an m-health solution, it has the potential to promote patient's self-management, as a complement to the doctor's intervention, and encourage greater participation in medical decision-making In conclusion, BPT has a potential key role in the management of patients with hypertension, since it seems to improve the quality of delivered care and allow for more effective prevention of the cardiovascular consequences of hypertension

The epidemiology of stroke in Africa: A systematic review of existing methods and new approaches

Abstract: Accurate epidemiological surveillance of the burden of stroke is direly needed to facilitate the development and evaluation of effective interventions in Africa. The authors therefore conducted a systematic review of the methodology of stroke epidemiological studies conducted in Africa from 1970 to 2017 using gold standard criteria obtained from landmark epidemiological publications. Of 1330 articles extracted, only 50 articles were eligible for review grouped under incidence, prevalence, case-fatality, health-related quality of life, and disability-adjusted life-years studies. Because of various challenges, no study fulfilled the criteria for an excellent stroke incidence study. The relatively few stroke epidemiology studies in Africa have significant methodological flaws. Innovative approaches leveraging available information and communication technology infrastructure are recommended to facilitate rigorous epidemiological studies for accurate stroke surveillance in Africa.

Home blood pressure control status in 2017-2018 for hypertension specialist centers in Asia: Results of the Asia BP@Home study.

Abstract: A self-measured home blood pressure (BP)-guided strategy is an effective practical approach to hypertension management. The Asia BP@Home study is the first designed to investigate current home BP control status in different Asian countries/regions using standardized home BP measurements taken with the same validated home BP monitoring device with data memory. We enrolled 1443 medicated hypertensive patients from 15 Asian specialist centers in 11 countries/regions between April 2017 and March 2018. BP was relatively well controlled in 68.2% of patients using a morning home systolic BP (SBP) cutoff of <135 mm Hg, and in 55.1% of patients using a clinic SBP cutoff of <140 mm Hg. When cutoff values were changed to the 2017 AHA/ACC threshold (SBP <130 mm Hg), 53.6% of patients were well controlled for morning home SBP. Using clinic 140 mm Hg and morning home 135 mm Hg SBP thresholds, the proportion of patients with well-controlled hypertension (46%) was higher than for uncontrolled sustained (22%), white-coat (23%), and masked uncontrolled (9%) hypertension, with significant country/regional differences. Home BP variability in Asian countries was high, and varied by country/region. In conclusion, the Asia BP@Home study demonstrated that home BP is relatively well controlled at hypertension specialist centers in Asia. However, almost half of patients remain uncontrolled for morning BP according to new guidelines, with significant country/regional differences. Strict home BP control should be beneficial in Asian populations. The findings of this study are important to facilitate development of health policies focused on reducing cardiovascular complications in Asia.

Beta-blocker subtypes and risk of low birth weight in newborns.

Abstract: Beta-blockers are one of the most commonly prescribed classes of antihypertensive medications during pregnancy. Previous studies reported an association between beta-blocker exposure and intrauterine growth restriction. Whether some beta-blocker subtypes may be associated with higher risk is not known. This is a retrospective cohort study of pregnant women exposed to beta-blockers in the Kaiser Permanente Southern California Region between 2003 and 2014. Logistic regression models were used to evaluate association between exposure to different beta-blocker agents and risk of low fetal birth weights. In a cohort of 379 238 singleton pregnancies, 4847 (1.3%) were exposed to beta-blockers. The four most commonly prescribed beta-blockers were labetalol (n = 3357), atenolol (n = 638), propranolol (n = 489), and metoprolol (n = 324). Mean birth weight and % low birth weight (<2500 g) were 2926 ± 841 g and 24.4% for labetalol, 3058 ± 748 g and 18.0% for atenolol, 3163 ± 702 g and 13.3% for metoprolol, 3286 ± 651 g and 7.6% for propranolol, and 3353 ± 554 g and 5.2% for non-exposed controls. Exposure to atenolol and labetalol were associated with increased risks of infant born small for gestational age (SGA) (atenolol: adjusted OR 2.4, 95% CI: 1.7-3.3; labetalol: adjusted OR 2.9, 95% CI: 2.6-3.2). Risk of SGA associated with metoprolol or propranolol exposure was not significantly different from the non-exposed group (metoprolol: adjusted OR 1.5, 95% CI: 0.9-2.3; propranolol: adjusted OR 1.3, 95% CI: 0.9-1.9). Association between beta-blocker exposure and SGA does not appear to be a class effect. Variations in pharmacodynamics and confounding by indication may explain these findings.

Management of morning hypertension: a consensus statement of an Asian expert panel.

Abstract: Morning blood pressure (BP) surge is an important aspect of hypertension research. Morning BP monitoring could be a clinically relevant concept in the therapeutic management of hypertension and in the prevention of cardiovascular complications by defining and treating morning hypertension. Because antihypertensive medication is often taken in the morning, uncontrolled morning BP during the trough effect hours could be a hallmark of inadequate choice of antihypertensive regimen, such as the use of short- or intermediate-acting drugs, underdosing of drugs, or no use or underuse of combination therapy. To improve the management of hypertension in general and morning hypertension in particular, long-acting antihypertensive drugs should be used in appropriate, often full dosages and in proper combinations. The clinical usefulness of antihypertensive drugs with specific mechanisms for morning BP or split or timed dosing of long-acting drugs in controlling morning BP remains under investigation.

Efficacy and safety of sacubitril/valsartan in patients with essential hypertension uncontrolled by olmesartan: A randomized, double-blind, 8-week study.

Abstract: A majority of patients with hypertension fail to achieve blood pressure (BP) control despite treatment with commonly prescribed drugs. This randomized, double-blind phase III trial assessed the superiority of sacubitril/valsartan 200 mg (97/103 mg) to continued olmesartan 20 mg in reducing ambulatory systolic BP after 8-week treatment in patients with mild to moderate essential hypertension uncontrolled with olmesartan 20 mg alone. A total of 376 patients were randomized to receive either sacubitril/valsartan (n = 188) or olmesartan (n = 188). Superior reductions in 24-hour mean ambulatory systolic BP were observed in the sacubitril/valsartan group vs the olmesartan group (-4.3 mm Hg vs -1.1 mm Hg, P < .001). Reductions in 24-hour mean ambulatory diastolic BP and pulse pressure and office systolic BP and diastolic BP were significantly greater with sacubitril/valsartan vs olmesartan (P < .014). A greater proportion of patients achieved BP control with sacubitril/valsartan vs olmesartan. The overall incidence of adverse events was comparable between the groups. Compared with continued olmesartan, sacubitril/valsartan was more effective and generally safe in patients with hypertension uncontrolled with olmesartan 20 mg.

Blood pressure variability and neurocognitive functioning.

Abstract: wileyonlinelibrary.com/journal/jch | 645 ©2018 Wiley Periodicals, Inc. Cognitive impairment is a worldwide public health and social care concern. It has striking consequences to patients, caregivers, and the healthcare system, and is an exponentially raising disease burden due to the aging population. Dementia affects approximately 1.5% of people aged 6570 years and the prevalence increases up to 25% among people aged 85 and over.1 According to the World Health Organization, around 50 million people currently suffer from dementia, and the number is continuously growing, with nearly 10 million of new cases every year.2 At this alarming rate, more than 115 million people are expected to be living with dementia by 2050.3 Hence, the development of measures aimed to prevent and delay the onset and progression of the cognitive deterioration represents a critical priority and emerging need.

The impact of fixed-dose combination versus free-equivalent combination therapies on adherence for hypertension: a meta-analysis

Abstract: Nonadherence to antihypertensive medication is considered as a reason of inadequate control of blood pressure. This meta-analysis aimed to systemically evaluate the impact of fixed-dose combination (FDC) therapy on hypertensive medication adherence compared with free-equivalent combination therapies. Articles were retrieved from MEDLINE and Embase databases using a combination of terms "fixed-dose combinations" and "adherence or compliance or persistence" and "hypertension or antihypertensive" from January 2000 to June 2017 without any language restriction. A meta-analysis was performed to parallel compare the impact of FDC vs free-equivalent combination on medicine adherence or persistence. Studies were independently reviewed by two investigators. Data from eligible studies were extracted and a meta-analysis was performed using R version 3.1.0 software. A total of nine studies scored as six of nine to eight of nine for Newcastle-Ottawa rating with 62 481 patients with hypertension were finally included for analysis. Results showed that the mean difference of medication adherence for FDC vs free-equivalent combination therapies was 14.92% (95% confidence interval, 7.38%-22.46%). Patients in FDC group were more likely to persist with their antihypertensive treatment, with a risk ratio of 1.84 (95% confidence interval, 1.00-3.39). This meta-analysis confirmed that FDC therapy, compared with free-equivalent combinations, was associated with better medication adherence or persistence for patients with hypertension. It can be reasonable for physicians, pharmacists, and policy makers to facilitate the use of FDCs for patients who need to take two or more antihypertensive drugs.

Prevalence and clinical outcomes of white-coat and masked hypertension: Analysis of a large ambulatory blood pressure database.

Abstract: The aim of this study was to analyze prevalence and clinical outcomes of the following clinical conditions: normotension (NT; clinic BP < 140/90 mm Hg; 24-hour BP < 130/80 mm Hg), white-coat hypertension (WCHT; clinic BP ≥ 140 and/or ≥90 mm Hg; 24-hour BP < 130/80 mm Hg), masked hypertension (MHT; clinic BP < 140/90 mm Hg; 24-hour BP ≥ 130 and/or ≥80 mm Hg), and sustained hypertension (SHT; clinic BP ≥ 140 and/or ≥90 mm Hg; 24-hour BP ≥ 130 and/or ≥80 mm Hg) in a large cohort of adult untreated individuals. Systematic research throughout the medical database of Regione Lazio (Italy) was performed to estimate incidence of myocardial infarction (MI), stroke, and hospitalizations for HT and heart failure (HF). Among a total study sample of 2209 outpatients, 377 (17.1%) had NT, 351 (15.9%) had WCHT, 149 (6.7%) had MHT, and 1332 had (60.3%) SHT. During an average follow-up of 120.1 ± 73.9 months, WCHT was associated with increased risk of hospitalization for HT (OR 95% CI: 1.927 [1.233-3.013]; P = .04) and HF (OR 95% CI: 3.449 [1.321-9.007]; P = .011). MHT was associated with an increased risk of MI (OR 95% CI: 5.062 [2.218-11.550]; P < .001), hospitalization for HT (OR 95% CI: 2.553 [1.446-4.508]; P = .001), and for HF (OR 95% CI: 4.214 [1.449-12.249]; P = .008). These effects remained statistically significant event after corrections for confounding factors including age, BMI, gender, smoking, dyslipidaemia, diabetes, and presence of antihypertensive therapies.

Monitoring and evaluation framework for hypertension programs. A collaboration between the Pan American Health Organization and World Hypertension League

Abstract: The Pan American Health Organization (PAHO)-World Hypertension League (WHL) Hypertension Monitoring and Evaluation Framework is summarized. Standardized indicators are provided for monitoring and evaluating national or subnational hypertension control programs. Five core indicators from the World Health Organization hearts initiative and a single PAHO-WHL core indicator are recommended to be used in all hypertension control programs. In addition, hypertension control programs are encouraged to select from 14 optional qualitative and 33 quantitative indicators to facilitate progress towards enhanced hypertension control. The intention is for hypertension programs to select quantitative indicators based on the current surveillance mechanisms that are available and what is feasible and to use the framework process indicators as a guide to program management. Programs may wish to increase or refine the number of indicators they use over time. With adaption the indicators can also be implemented at a community or clinic level. The standardized indicators are being pilot tested in Cuba, Colombia, Chile, and Barbados.

Association between hypertension and cognitive function: A cross-sectional study in people over 45 years old in China.

Abstract: This cross-sectional study aimed to evaluate the associations of characteristics of hypertension, including hypertension status, duration, blood pressure (BP), and pulse pressure (PP), with two cognitive functions-episodic memory and executive function, in people aged over 45 years. Using 2013 survey of the China Health and Retirement Longitudinal Study (CHARLS) and weighted multiple linear regression, data from 6,732 participants were utilized. After fully adjusted in full sample, a significantly (P < 0.05) negative association was found between treated but uncontrolled hypertension and cognition. In people aged 45-59 years, there was no significant association between hypertension and cognition. However, in people aged ≥60 years, the systolic blood pressure (SBP) and PP showed significantly adverse correlations to cognition. The negative association of untreated, treated but uncontrolled hypertension, and elevated PP with cognition increased with aging. In conclusion, this study shows the correlation between hypertension and cognition was age-dependent with greater correlation in older people; uncontrolled hypertension and PP may be used as predictors of the cognitive decline in people ≥75 years.

The effects of age on pulse wave velocity in untreated hypertension

Abstract: Increased arterial stiffness is an important determinant of cardiovascular risk, able to predict morbidity and mortality, and closely associated with ageing and blood pressure. The aims of this study were: (1) To determine the age-dependent reference pulse wave velocity (PWV), and compare it with values from hypertensive patients, and (2) to evaluate the impact of isolated and untreated hypertension on arterial stiffness. A total of 1079 patients were enrolled and divided into a control group (NT) of asymptomatic normotensive patients and a group of asymptomatic hypertensive patients (HT). Blood pressure, carotid-femoral PWV, and body mass index were measured in each subject, whose blood was drawn for laboratory tests. Aortic mean PWV in the NT group was 6.85 ± 1.66 m/s, which increased linearly (R2 = 0.62; P < .05) with age. In patients over 50 years of age, PWV was significantly higher than in younger patients (8.35 vs 5.92 m/s, respectively, P < .001). This significant difference persisted when observing male and female patients separately. In the hypertensive group, mean PWV value was 8.04 ± 1.8 m/s (range 4.5-15.8 m/s) and increased (R2 = 0.243; P < .05) with age. The PWV increase in HT was significantly higher (0.93 m/s per decade, P < .001) than in NT (0.44 m/s per decade). Our study provides normal values of PVW per decade, and shows that these values increase with age, especially after 50 years of age, particularly in HT patients. This stiffness growth rate may be responsible for increased cardiovascular risk in both groups.

Effects of aerobic interval training on arterial stiffness and microvascular function in patients with metabolic syndrome.

Abstract: The authors determined the effect of high-intensity aerobic interval training on arterial stiffness and microvascular dysfunction in patients with metabolic syndrome with hypertension. Applanation tonometry was used to measure arterial stiffness and laser Doppler flowmetry to assess microvascular dysfunction before and after 6 months of stationary cycling (training group; n = 23) in comparison to a group that remained sedentary (control group; n = 23). While no variable improved in controls, hypertension fell from 79% (59%-91%) to 41% (24%-61%) in the training group, resulting in lower systolic and diastolic pressures than controls (-12 ± 3 and -6 ± 2 mm Hg, P < .008). Arterial stiffness declined (-17% augmentation index, P = .048) and reactive hyperemia increased (20%, P = .028) posttreatment in the training group vs controls. Blood constituents associated with arterial stiffness and a prothrombotic state (high-sensitivity C-reactive protein, fibrinogen, platelets, and erythrocytes) remained unchanged in the training and control groups. In summary, 6 months of an intense aerobic exercise program reduced both arterial stiffness and microvascular dysfunction in patients with metabolic syndrome despite unchanged blood-borne cardiovascular risk factors. Training lowers blood flow resistance in central and peripheral vascular beds in a coordinated fashion, resulting in clinically relevant reductions in hypertension.

Sex-related relationships between uric acid and target organ damage in hypertension.

Abstract: Heterogeneous results have been obtained in the relationship between serum uric acid (SUA) and target organ damage (TOD) in patients with hypertension. Clinic blood pressure, SUA, and cardiac, arterial (carotid and aortic), and renal TOD were assessed in 762 consecutive patients with hypertension. Hyperuricemia was defined as an SUA >7.0 in men and >6.0 mg/dL in women. Men with hyperuricemia compared with those with normal SUA showed lower estimated glomerular filtration rates and E/A ratios and a higher prevalence of carotid plaques. Women with hyperuricemia showed lower estimated glomerular filtration rates and E/A ratios and a higher intima-media thickness. Except for pulse wave velocity, all TODs significantly correlated with SUA. However, at multivariate analysis, only estimated glomerular filtration rate was significantly determined by SUA. Our data provide evidence on the role of SUA in the development of TOD only in the case of renal alteration. It is likely that SUA may indirectly act on the other TODs through the increase in blood pressure and the decrease in glomerular filtration rate.

Measure Accurately, Act Rapidly, and Partner With Patients (MAP) improves hypertension control in medically underserved patients: Care Coordination Institute and American Medical Association Hypertension Control Project Pilot Study results

Abstract: Measure Accurately, Act Rapidly, and Partner With Patients (MAP) is an evidence-based protocol implemented to improve hypertension control in a clinic for underserved patients (49.9% Medicaid and 50.2% black). Patients with hypertension seen during the year before intervention and with at least one visit during the 6-month intervention (N = 714) were included. If initial attended blood pressure (BP; standard aneroid manometer) was ≥140/≥90 mm Hg, unattended automated office BP was measured in triplicate and averaged (Measure Accurately) using an Omron HEM-907XL. When automated office BP was ≥140/≥90 mm Hg, Act Rapidly included intensification of antihypertensive medications, assessed by therapeutic inertia. Partner With Patients included BP self-monitoring, reducing pill burden, and minimizing medication costs, which was assessed by systolic BP change per therapeutic intensification. Between baseline and the last study visit, BP control to <140/<90 mm Hg increased from 61.2% to 89.9% (P < .0001). MAP rapidly and significantly improved hypertension control in medically underserved patients, largely as a result of measuring BP accurately and partnering with patients.
