  • What We Do and Do Not Know About Women and Kidney Diseases; Questions
           Unanswered and Answers Unquestioned: Reflection on World Kidney Day and
           International Woman’s Day
    • Authors: Piccoli G; Alrukhaimi M, Liu Z, et al.
      Pages: 375 - 384
      Abstract: Chronic kidney disease (CKD) affects approximately 10% of the world’s adult population: it is within the top 20 causes of death worldwide,1 and its impact on patients and their families can be devastating. World Kidney Day and International Women’s Day in 2018 coincide, thus offering an opportunity to reflect on the importance of women’ s health and specifically their kidney health, on the community, and the next generations; as well as to strive to be more curious about the unique aspects of kidney disease in women, so that we may apply those learnings more broadly.

  • Single Pill Combinations as Initial Therapy in the Management of
           Hypertension: What is Taking you so Long'
    • Authors: Feldman R.
      Pages: 263 - 264
      Abstract: In 2017, 2 respected hypertension guidelines, those of Hypertension Canada and those of the Latin American Society of Hypertension added another treatment to their listing of first line (initial) pharmacological therapy for hypertension.1,2 This event, unlikely to be reported by CNN or Fox was still newsworthy for 2 reasons. First, it is the only new therapy added to that list in almost 2 decades (at least in Canada). Second, the therapy was one that had been used in hypertension for more than 50 years. The treatment' Single pill combinations (SPCs) of 2 antihypertensive drugs. The examination of the duration of time it took from the initial introduction of SPCs in therapy to their recognition as first line in an increasing number of countries (but not in the United States) is illustrative of the limitations of our current approach in the identification and implementation of best practices.

  • New Methods to Study the Microcirculation
    • Authors: Rizzoni D; Agabiti Rosei C, De Ciuceis C, et al.
      Pages: 265 - 273
      Abstract: Essential hypertension is associated with structural alterations in the microvessels; in particular, an increase in the media thickness to internal lumen ratio of small resistance arteries (MLR) and a reduction in capillary density have been observed. The evaluation of the morphological characteristics of small resistance arteries in humans is challenging. The gold-standard method is generally considered to be the measurement by wire or pressure micromyography of MLR of subcutaneous small vessels obtained by local biopsies. However, noninvasive techniques for the evaluation of retinal arterioles were recently proposed; in particular, 2 approaches, scanning laser Doppler flowmetry (SLDF) and adaptive optics (AO), seem to provide useful information. Both of them provide an estimation of the wall to lumen ratio (WLR) of retinal arterioles. Moreover, a noninvasive measurement of basal and total capillary density may be obtained by videomicroscopy/capillaroscopy. It has been recently demonstrated that AO has a substantial advantage over SLDF in terms of evaluation of microvascular morphology, since WLR measured with AO is more closely correlated with the M/L of subcutaneous small arteries. The possibility to noninvasively assess in a reliable way, microvascular morphology in a clinical setting may represent a major advancement, since micromyography has substantial limitations in its application due to the local invasiveness of the procedure.

      Abstract: Resistant hypertension (RH) is a multifactorial disease associated with several target organ damage, such as microalbuminuria, left ventricular hypertrophy, and arterial stiffness. These subjects have high cardiovascular complications, especially when associated with diabetes condition. Sodium glucose cotransporter 2 (SGLT-2) inhibitors represent a new class of oral antidiabetic drugs that have shown positive effects in diabetics and even hypertensives subjects. Several studies demonstrated positive outcomes related to blood pressure levels, body weight, and glycemic control. Also found a reduction on microalbuminuria, cardiac and arterial remodeling process, and decrease in hospitalization care due heart failure. Despite these positive effects, the outcomes found for stroke were conflicted and tend neutral effect. Based on this, we sought to assess the pleiotropic effects of SGLT-2 inhibitors and the possible impact in RH subjects. In order to analyze the prospects of SGLT-2 inhibitors as a possible medication to complement the therapy manage of this high-risk class of patients.

      Pages: 281 - 283
      Abstract: More than two-thirds of elderly persons (≥65 years) in the United States have hypertension.1 In addition, prospective cohort studies have shown that aging is significantly associated with hypertension prevalence. For example, the Framingham Heart Study reported that the prevalence of hypertension increased from 27.3% in individuals <60 years to 74.0% in those >80 years.2 As hypertension is a major risk factor for cardiovascular morbidities and mortalities, especially in the elderly, treating hypertension in older individuals is an important task for clinicians.

      Abstract: Hypertension is a leading risk factor for premature morbidity and mortality in developed and developing countries.1 It is a common cause of cerebrovascular disease and a major contributor to the global burden of ischemic heart disease and heart failure.1 Several cardiac alterations may be present in hypertensive patients, which include cardiac structural and functional changes (increased left ventricular [LV] mass, LV systolic and diastolic dysfunction, and impairment of coronary reserve), arrhythmias, and enlargement of left atrial and aortic root.2 Within the array of such abnormalities, considerable attention has been paid to LV hypertrophy for its negative association with major cardiovascular events and survival.3,4 LV hypertrophy, either diagnosed by ECG or echocardiography,5,6 reflects a dangerous vicious circle characterized by endothelial dysfunction, intrinsic myocyte impairment, ischemia, myocardial fibrosis, and apoptosis.

  • Adherence to Antihypertensive Therapy: A Missing Link Between Treatment
           and Outcomes
    • Authors: Bharti S; Bharti B.
      Pages: 290 - 292
      Abstract: The metric of “adherence” simply captures concordance of patient’s self management behavior with mutually agreed health care recommendations. With increasing burden of chronic diseases, adherence to pharmacological, and nonpharmacological measures has emerged as an essential reinforcer to treatment effectiveness. Alarmingly, poor adherence to antihypertensive medication (AHM) is fuelling the public health crisis of unsuccessfully treated hypertension, negatively impacting cardiovascular, cerebrovascular, and renal outcomes.1 A study carried out in 5 European countries forecasted 6,553 fewer hypertensive complications with cost saving of €36 billion over a decade if 70% of patients take >80% of their AHM.2 Indeed, poor adherence to blood pressure (BP) lowering medication cuts across various groups such as gender, race, marital status, comorbidities, and is not driven by one particular demographic or biopsychosocial stereotype. Research over last few decades had aptly dissipated the long held paternalistic belief of “blame the patient” for poor adherence.1 WHO’s multidimensional adherence model has broadly classified reasons for poor adherence into 5 domains—socioeconomic factors, health care team- and system-related factors, condition-related factors, therapy-related factors, and patient-related factors.1 In this backdrop, study by Fortuna et al. in current issue evaluated the health care team- and system-related dimension highlighting importance of participatory patient provider management with shared decision making in optimizing adherence to AHM therapy.3 Using 8-item Morisky Medication Adherence Scale, 29.7% of patients reported high adherence (score 8), 32.8% reported moderate adherence (score 6–7), and 37.5% (score <6) reported low adherence and there was linear positive correlation between Morisky Medication Adherence Scale score and BP control rate. Notably, quality and not the quantity of time spent by health care provider in the care of hypertensive patient was significant predictor of adherence in their study. However, downside of their study includes an observational design, nonprobability sampling and overfitting the logistic regression model due to higher prevalence of dependent outcome. Moreover, among 3 components of adherence (initiation of therapy, day to day implementation of prescribed dosing, and long-term persistence with therapy), the current study only reported implementation bottlenecks between actual and prescribed antihypertensive therapy. Importantly, it is also reported that 5% of the hypertensive patients fail to initiate treatment after prescribing, nearly 10% skip their scheduled doses on a given day (half of them have “drug holiday” lapses of >3 days) and about 50% default within 1 year of treatment initiation.4 The summary of recent meta-analyses of studies evaluating adherence to AHM are tabulated in Table 1.

  • Relationship Between Blood Pressure Variability and Cognitive Function in
           Elderly Patients With Good Blood Pressure Control
    • Authors: Cho N; Hoshide S, Nishizawa M, et al.
      Pages: 293 - 298
      Abstract: BACKGROUNDAlthough higher blood pressure (BP) levels and BP variability have been associated with cognitive impairment, data are sparse regarding the relationship between BP variability and cognitive function in elderly patients with well BP control.METHODSWe analyzed 232 ambulatory patients with one or more cardiovascular risk factors. All patients underwent ambulatory BP monitoring and the Japanese version of the Montreal Cognitive Assessment (MoCA-J).RESULTSThe mean age was 77.7 ± 8.3 years; 33.6% were male, and 85.3% were taking antihypertensive drugs. The average 24-hour BP level was 118.7 ± 10.0/68.3 ± 6.4 mm Hg. When we divided the weighted SD of systolic BP (SBP) as a measure of BP variability into quartiles, the top quartile group (≥19.6 mm Hg) had a significantly lower total MoCA-J score (15.4 [95% confidence interval 14.2–16.7] vs. 17.9 [17.2–18.6], P = 0.001) and lower scores on several domains, visuoexecutive (2.2 [1.9–2.6] vs. 2.8 [2.6–2.9], P = 0.012), abstraction (1.0 [0.7–1.2] vs. 1.3 [1.1–1.4], P = 0.015), attention (2.8 [2.4–3.1] vs. 3.6 [3.4–3.8], P = 0.001), and naming (2.1 [1.9–2.3] vs. 2.5 [2.4–2.6], P = 0.001) than quartiles 1 through 3 combined, after adjustment for age and 24-hour SBP. These associations were not found in the quartiles of 24-hour SBP.CONCLUSIONSIn elderly patients with well ambulatory BP control, higher BP variability but not average ambulatory BP level was associated with cognitive impairment.

  • Identification of the Optimal Protocol for Automated Office Blood Pressure
           Measurement Among Patients With Treated Hypertension
    • Authors: Moore M; Schultz M, Nelson M, et al.
      Pages: 299 - 304
      Abstract: BACKGROUNDAutomated office blood pressure (AOBP) involving repeated, unobserved blood pressure (BP) readings during one clinic visit is recommended for in-office diagnosis and assessment of hypertension. However, the optimal AOBP protocol to determine BP control in the least amount of time with the fewest BP readings is yet to be determined and was the aim of this study.METHODSOne hundred and eighty-nine patients (mean age 62.8 ± 12.1 years; 50.3% female) with treated hypertension referred to specialist clinics at 2 sites underwent AOBP in a quiet room alone. Eight BP measurements were taken starting immediately after sitting and then at 2-minute intervals (15 minutes total). The optimal AOBP protocol was defined by the smallest mean difference and highest intraclass correlation coefficient (ICC) compared with daytime ambulatory BP (ABP). The same BP device (Mobil-o-graph, IEM) was used for both AOBP and daytime ABP.RESULTSAverage 15-minute AOBP and daytime ABP were 134 ± 22/82 ± 13 and 137 ± 17/83 ± 11 mm Hg, respectively. The optimal AOBP protocol was derived within a total duration of 6 minutes from the average of 2 measures started after 2 and 4 minutes of seated rest (systolic BP: mean difference (95% confidence interval) 0.004(−2.21, 2.21) mm Hg, P = 1.0; ICC = 0.81; diastolic BP: mean difference 0.37(−0.90, 1.63) mm Hg, P = 0.57; ICC = 0.86). AOBP measures taken after 8 minutes tended to underestimate daytime ABP (whether as a single BP or the average of more than 1 BP reading).CONCLUSIONSOnly 2 AOBP readings taken over 6 minutes (excluding an initial reading immediately after sitting) may be needed to be comparable with daytime ABP.

  • Correlation of Blood Pressure Variability as Measured By Clinic,
           Self-measurement at Home, and Ambulatory Blood Pressure Monitoring
    • Authors: Abellán-Huerta J; Prieto-Valiente L, Montoro-García S, et al.
      Pages: 305 - 312
      Abstract: BACKGROUNDBlood pressure variability (BPV) has been postulated as a potential predictor of cardiovascular outcomes. No agreement exists as to which measurement method is best for BPV estimation. We attempt to assess the correlation between BPV obtained at the doctor’s office, self-measurement at home (SMBP) and ambulatory BP monitoring (ABPM).METHODSEight weekly clinic BP measurements, 2 SMBP series, and 1 24-hour ABPM recording were carried out in a sample of treated hypertensive patients. BPV was calculated using the SD, the “coefficient of variation” and the “average real variability.” Determinants of short-, mid-, and long-term BPV (within each measurement method) were also calculated. The different BPV determinants were correlated “intramethod” and “intermethod” by linear regression test.RESULTSFor the 104 patients (66.5 ± 7.7 years, 58.7% males), the ABPM BPV (SD, systolic/diastolic: 14.5 ± 3.1/9.8 ± 2.5 mm Hg) was higher than the SMBP (12.2 ± 9.8/7.4 ± 5.8 mm Hg; P < 0.001) and clinic BPV (10 ± 8.9/5.9 ± 4.9 mm Hg; P = 0.001). The main BPV correlation between methods was weak, with a maximum R2 = 0.17 (P < 0.001) between clinic and SMBP systolic BPV. The “intramethod” correlation of BPV yielded a maximum R2 = 0.21 (P < 0.001) between morning diastolic SMBP intershift/intermeans variability. The “intermethod” correlation of short-, mid-, and long-term BPV determinants was weak (maximum R2 = 0.22, P < 0.001, between clinic intraday variability/SMBP morning intershift variability).CONCLUSIONSThe “intramethod” and “intermethod” correlation between BPV determinants was weak or nonexistent, even when comparing determinants reflecting the same type of temporal BPV. Our data suggest that BPV reflects a heterogeneous phenomenon that strongly depends on the estimation method and the time period evaluated.

  • Left Ventricular Hypertrophy Predicts Cardiovascular Events in
           Hypertensive Patients With Coronary Artery Calcifications
    • Authors: Grossman C; Levin M, Koren-Morag N, et al.
      Pages: 313 - 320
      Abstract: BACKGROUNDCoronary artery calcification (CAC) is associated with increased cardiovascular (CV) risk. Left ventricular hypertrophy (LVH) is an independent risk factor for CV events. Our aim was to estimate the relative CV risk of LVH in the presence of CAC.METHODSWe included asymptomatic hypertensive patients who were enrolled in the calcification arm of the INSIGHT (International Nifedipine Study Intervention as Goal for Hypertension Therapy). Patients had baseline echocardiography and computed tomography to assess CAC. The primary end-point was the first CV event.RESULTSTwo hundred and fifty-two subjects (mean age 64.7 ± 5.5 years, 54% men) were followed for a mean of 13.3 ± 2.6 years. 72 patients (28.5%) had LVH and 159 patients (63%) had CAC. During follow up, 89 patients had a first CV event. The rate of CV events was higher in those with than in those without CAC (43.4% vs. 21.5%, P < 0.01) and in those with than in those without LVH (44% vs. 31.6%, P < 0.01). However, LVH had no effect on CV events in the absence of CAC, whereas LVH almost doubled the rate of CV events (61.4% vs. 36.5%, P < 0.01) in the presence of CAC. In comparison to patients without CAC and without LVH the hazard ratio for CV event in those with LVH was 1.46 (95% confidence interval [CI], 0.50–4.21) in those without CAC and 4.4 (95% CI, 2.02–9.56) in those with CAC.CONCLUSIONSLVH and CAC independently predict CV events in asymptomatic hypertensive patients. However, the risk of LVH is mainly observed in those with CAC.

  • Echocardiographic Left Ventricular Reverse Remodeling After 18 Months of
           Antihypertensive Treatment in Stage I Hypertension. Results From the
           Prever-Treatment Study
    • Authors: Bertoluci C; Foppa M, Santos A, et al.
      Pages: 321 - 328
      Abstract: BACKGROUNDAntihypertensive treatment improves echocardiographic parameters of hypertensive target organ damage in stage II hypertension, but less is known about the effects in stage I hypertension.METHODSIn a cohort study nested in the randomized double-blind trial PREVER-treatment, 2-dimensional echocardiograms were performed in 110 individuals, aged 54.8 ± 7.9 years-old, with stage I hypertension at baseline and after 18 months of treatment with chlorthalidone/amiloride or losartan.RESULTSAt baseline, 66 (60%) participants had concentric remodeling. After antihypertensive treatment, systolic (SBP) and diastolic blood pressure (BP) were reduced from 141/90 to 130/83 mm Hg (P = 0.009). There was a significant reduction in left ventricular (LV) mass (LVM) index (82.7 ± 17.1 to 79.2 ± 17.5 g/m2; P = 0.005) and relative wall thickness (0.45 ± 0.06 to 0.42 ± 0.05; P < 0.001), increasing the proportion of participants with normal LV geometry (31% to 49%, P = 0.006). Left atrial (LA) volume index reduced (26.8 ± 7.3 to 24.9 ± 6.5 ml/m2; P = 0.001), and mitral E-wave deceleration time increased (230 ± 46 to 247 ± 67 ms; P = 0.005), but there was no change in other parameters of diastolic function. LVM reduction was significantly higher in the 2 higher tertiles of SBP reduction compared to the lower tertile.CONCLUSIONSTreatment of patients with stage I hypertension for 18 months promotes favorable effects in the LA and LV remodeling. This improvement in cardiac end-organ damage might be associated with reduction of long term clinical consequences of hypertensive cardiomyopathy, particularly heart failure with preserved ejection fraction.

  • Intradialytic Hypertension Frequency and Short-Term Clinical Outcomes
           Among Individuals Receiving Maintenance Hemodialysis
    • Authors: Assimon M; Wang L, Flythe J.
      Pages: 329 - 339
      Abstract: BACKGROUNDIntradialytic hypertension occurs in 5–20% of hemodialysis treatments. Observational data support an association between intradialytic hypertension and long-term mortality. However, the short-term consequences of recurrent intradialytic hypertension are unknown.METHODSData were taken from a cohort of prevalent hemodialysis patients receiving treatment at a large United States dialysis organization on 1 January 2010. A retrospective cohort design with a 180-day baseline, 30-day exposure assessment, and 30-day follow-up period was used to estimate the associations between intradialytic hypertension frequency and 30-day outcomes. Intradialytic hypertension frequency was defined as the proportion of exposure period hemodialysis treatments with a predialysis to postdialysis systolic blood pressure rise >0 mm Hg. Multivariable Cox proportional hazards regression, adjusted for baseline clinical, laboratory, and dialysis treatment covariates, was used to estimate hazard ratios and 95% confidence intervals.RESULTSOf the 37,094 study patients, 5,242 (14.1%), 17,965 (48.4%), 10,821 (29.2%), 3,066 (8.3%) had intradialytic hypertension in 0%, 1–32%, 33–66%, and ≥67% of exposure period treatments, respectively. More frequent intradialytic hypertension was associated with incremental increases in 30-day mortality and hospitalizations. Patients with intradialytic hypertension in ≥67% (vs. 0%) of exposure period treatments had the highest risk of all-cause death, hazard ratio [95% confidence interval]: 2.57 [1.68, 3.94]; cardiovascular (CV) death, 3.68 [1.89, 7.15]; all-cause hospitalizations, 1.42 [1.26, 1.62]; CV hospitalizations, 1.71 [1.36, 2.15]; and volume-related hospitalizations, 2.25 [1.25, 4.04].CONCLUSIONSAmong prevalent hemodialysis patients, more frequent intradialytic hypertension was incrementally associated with increased 30-day morbidity and mortality. Intradialytic hypertension may be an important short-term risk marker in the hemodialysis population.

  • Patient Experience With Care and Its Association With Adherence to
           Hypertension Medications
    • Authors: Fortuna R; Nagel A, Rocco T, et al.
      Pages: 340 - 345
      Abstract: BACKGROUNDMedication adherence is crucial to effective chronic disease management, yet little is known about the influence of the patient–provider interaction on medication adherence to hypertensive regimens. We aimed to examine the association between the patient’s experience with care and medication adherence.METHODSWe collected 2,128 surveys over 4 years from a convenience sample of hypertensive patients seeking care at three urban safety-net practices in upstate New York. The survey collected adherence measures using the Morisky Medication Adherence Scale (MMAS-8) and patient experience measures. We used regression models to adjust for age, gender, race/ethnicity, self-reported health status, and clustering by patients. The primary outcome was reporting of medium-to-high adherence (MMAS ≥ 6) vs. low adherenceRESULTSA total of 62.5% of respondents reported medium-to-high medication adherence. The concern the provider demonstrated for patient questions or worries (adjusted odds ratio [AOR] 1.4; 95% confidence interval [CI] 1.1–1.7), provider efforts to include the patient in decisions (AOR 1.5; 95% CI 1.8–1.9), information given (AOR 1.3; 95% CI 1.0–1.6), and the overall rating of care received (AOR 1.4; 95% CI 1.1–1.8) were associated with higher medication adherence. The amount of time the provider spent was not associated with medication adherence (AOR 1.2; 95% CI 0.9–1.4). Medium-to-high medication adherence was in turn associated with increased hypertension control rates.CONCLUSIONSOverall, better experiences with care were associated with higher adherence to hypertension regimens. However, the amount of time the provider spent with the patient was not statistically associated with medication adherence, suggesting that the quality of communication may be more important than the absolute quantity of time.

  • Prevalence of Hypertension Defined by Central Blood Pressure Measured
           Using a Type II Device in a Nationally Representative Cohort
    • Authors: Chuang S; Chang H, Cheng H, et al.
      Pages: 346 - 354
      Abstract: OBJECTIVESCentral blood pressure (BP) can be used to define hypertension. A central BP approach may be more sensitive than a conventional brachial BP approach in detecting hypertension. We aimed to compare the 2 approaches in estimating the prevalence hypertension in a nationally representative population.METHODSA total of 2,742 adults older than 19 years participated in the 2013–2016 National Nutrition and Health Survey in Taiwan. Central and brachial BP were simultaneously measured using a cuff-based stand-alone central BP monitor purporting to measure invasive central BP (type II device). Central hypertension was defined by central systolic (SBP)/diastolic BP (DBP) ≥130 or 90 mm Hg or using antihypertensive medications, and brachial hypertension was defined by brachial SBP/DBP ≥140 or 90 mm Hg or using antihypertensive medications.RESULTSThe World Health Organization-standardized and national weighted prevalence rates of central hypertension were 27.95% and 32.48%, respectively, and both were significantly higher than those of brachial hypertension (20.80% and 25.43%, both P < 0.001). The national weighted prevalence rates of concordant central and brachial hypertension, concordant central and brachial nonhypertension, isolated central hypertension, and isolated brachial hypertension were 25.13%, 67.22%, 7.35%, and 0.30%, respectively. Most subjects with the isolated central hypertension (97%) were within the range of brachial prehypertension, but only 38.0% of subject with brachial prehypertension had central hypertension.CONCLUSIONAlmost one-third of a nationally representative population had hypertension detected by a central BP approach. Hypertension detection using a conventional brachial BP approach may underestimate the prevalence of hypertension and result in a less effective hypertension control.

  • Angiotensin Receptor Expression and Vascular Endothelial Dysfunction in
           Obstructive Sleep Apnea
    • Authors: Khayat R; Varadharaj S, Porter K, et al.
      Pages: 355 - 361
      Abstract: BACKGROUNDObstructive sleep apnea (OSA) is associated with vascular endothelial dysfunction (VED) in otherwise healthy patients. The role of renin–angiotensin system (RAS) in the OSA induced VED is not well understood.METHODSRecently diagnosed OSA patients with very low cardiovascular disease (CVD) risk (Framingham score <5%) were studied at diagnosis and after 12 weeks of verified continuous positive airway pressure (CPAP) therapy. Participants underwent biopsy of gluteal subcutaneous tissue at baseline and after CPAP. Microcirculatory endothelial expression of angiotensin receptors type-1 (AT-1) and type-2 (AT-2) was measured in the subcutaneous tissue using quantitative confocal microscopy techniques. The ex-vivo effect of AT-1 receptor blockade (ARB) on endothelial superoxide production was also measured before and after CPAP treatment.RESULTSIn OSA patients (n = 11), microcirculatory endothelial AT1 expression decreased from 873 (200) (fluorescence units) at baseline to 393 (59) units after 12 weeks of CPAP (P = 0.02). AT2 expression did not decrease significantly in these patients (479 (75) to 329 (58) post CPAP (P = 0.08)). The ex-vivo addition of the losartan to the microcirculatory endothelium resulted in decreased superoxide expression in the vascular walls from 14.2 (2.2) units to 4.2 (0.8) P < 0.001; while it had no effect on post-CPAP patient tissue (P = 0.64).CONCLUSIONSIn OSA patients with no to minimal CVD risk, VED is associated with upregulation of AT-1 expression that is reversible with CPAP. Endothelial oxidative stress was reversible with ARB. RAS activation may play an important role in the development of early CVD risk in OSA patients.

  • Acute Response to a 2-Minute Isometric Exercise Test Predicts the Blood
           Pressure-Lowering Efficacy of Isometric Resistance Training in Young
           Adults
    • Authors: Somani Y; Baross A, Brook R, et al.
      Pages: 362 - 368
      Abstract: BACKGROUNDThis work aimed to explore whether different forms of a simple isometric exercise test could be used to predict the blood pressure (BP)-lowering efficacy of different types of isometric resistance training (IRT) in healthy young adults. In light of the emphasis on primary prevention of hypertension, identifying those with normal BP who will respond to IRT is important. Also, heightened BP reactivity increases hypertension risk, and as IRT reduces BP reactivity in patients with hypertension, it warrants further investigation in a healthy population.METHODSForty-six young men and women (24 ± 5 years; 116 ± 10/ 68 ± 8 mm Hg) were recruited from 2 study sites: Windsor, Canada (n = 26; 13 women), and Northampton, United Kingdom (n = 20; 10 women). Resting BP and BP reactivity to an isometric exercise test were assessed prior to and following 10 weeks of thrice weekly IRT. Canadian participants trained on a handgrip dynamometer (isometric handgrip, IHG), while participants in the UK trained on an isometric leg extension dynamometer (ILE).RESULTSMen and women enrolled in both interventions demonstrated significant reductions in systolic BP (P < 0.001) and pulse pressure (P < 0.05). Additionally, test-induced systolic BP changes to IHG and ILE tests were associated with IHG and ILE training-induced reductions in systolic BP after 10 weeks of training, respectively (r = 0.58 and r = 0.77; for IHG and ILE; P < 0.05).CONCLUSIONSThe acute BP response to an isometric exercise test appears to be a viable tool to identify individuals who may respond to traditional IRT prescription.

      Abstract: BACKGROUNDHypertension is an important risk factor for cardiovascular disease. Activin A, a member of the transforming growth factor-β cytokine family, has been shown to regulate blood pressure through the renin–angiotensin system. However, the relationship between activin A and blood pressure remains uncertain. The objective of this study was to determine whether serum activin A levels are associated with blood pressure.METHODA total of 470 participants of I-Lan longitudinal Aging Study (ILAS) were eligible for this study. Serum levels of activin A were assessed by enzyme-linked immunosorbent assay. Cross-sectional analyses were performed, including comparisons of demographic characteristics, hypertensive status, and activin A levels.RESULTSAmong the study participants (50% men, mean age, 69 years), 236 (50.2%) were hypertensive and 234 (49.8%) were normotensive. Hypertensive patients had significantly higher serum activin A levels than normotensives (normotensive vs. hypertensive: 507 ± 169 vs. 554 ± 176 pg/ml, mean ± SD, P < 0.001). All subjects were divided into 3 tertiles on the basis of serum activin A levels. Increasing tertiles of activin A were associated with higher systolic blood pressure (SBP), diastolic blood pressure and pulse pressure (PP) (all P < 0.001). After adjusting for all the potential confounding factors, serum activin A concentration was still significantly associated with SBP (P = 0.02) and PP (P = 0.03).CONCLUSIONSSerum activin A level was associated with SBP and PP. Further studies are required to assess their causal relationship and the clinical relevance.
