Coarctation of the aorta is an uncommon cause of treatment-resistant hypertension in adults. It is typically detected and treated in infancy or childhood with surgical or endovascular procedures. Most cases of recurrence of coarctation after repair occur in childhood or early adulthood; recurrence in older persons (>70 years) has rarely been reported. A 73-year-old woman was referred to us for the management of treatment-resistant hypertension accompanied by symptoms of claudication and headaches, which had resulted in multiple emergency room visits...

We conducted a post hoc analysis of blood pressure (BP) data from long-term antihypertensive trials to identify predictors of visit-to-visit BP variability (BPV). BPV was defined as the within-subject coefficient of variation in systolic BP from week 12 onward. BP data from the Anglo-Scandinavian Cardiac Outcomes Trial-Blood Pressure Lowering Arm, Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial, Comparison of Amlodipine Versus Enalapril to Limit Occurrences of Thrombosis, NY92011, and R-0510 trials were pooled and dichotomized into top 25th and bottom 75th percentiles because of positive skew...

Ambulatory blood pressure monitoring (ABPM) can identify phenotypes that cannot be measured in the clinic. Determining race and sex disparities in ABPM measures among HIV+ individuals may improve strategies to diagnose and treat hypertension in this high-risk population. We compared ABPM measures between 24 African-American and 25 white HIV+ adults (36 men and 13 women). Awake systolic blood pressure (SBP) and diastolic blood pressure (DBP) were similar in African-Americans and whites. After multivariable adjustment, sleep SBP and DBP were 9...

We evaluated the prognostic impact of a complex remodeling classification (CRC) in asymptomatic patients with arterial hypertension (AH). We retrospectively included 749 hypertensive patients (female 325, 43.4% age 62 ± 11.3 years) in Stages A and B of heart failure. CRC was evaluated including indexed left ventricular mass, end-diastolic volume, and relative wall thickness. After 45-month follow-up, we considered a composite endpoint: total mortality, myocardial infarction, myocardial revascularization, cerebrovascular events, and acute pulmonary edema...

Chronic aerobic exercise training exhibits blood pressure protective effects, but the mechanism in metabolic level remains largely unclear. This study aims to investigate the effect of exercise training from serum metabolic profiles on the development of hypertension in spontaneously hypertensive rats (SHRs). Exercise training was performed, and the serum metabolites were measured by integrating gas chromatography-mass spectrometer and correlation-based network analysis. After a period of 6 weeks of chronic aerobic exercise training, systolic blood pressure was significant lower in the exercise training group (SHR + EX) rats than the control group (SHR)...

Hypertension represents a major global health burden. While older individuals of African descent are at higher risk of hypertension in western countries, epidemiologic data on hypertension in older native Africans are scarce. We assessed the prevalence and the level of awareness and control of hypertension among older adults in Central Africa. A total of 1990 individuals aged 65 years and older from the Republic of Congo and the Central African Republic participated into a cross-sectional population-based survey...

Global longitudinal strain (GLS), assessed by speckle tracking echocardiography, is a sensitive marker of myocardial systolic function and an independent predictor of cardiovascular outcomes. The aim of this study was to investigate the effect of hypotensive treatment on GLS and evaluate the relation between change in GLS and left ventricular (LV) diastolic function. In a group of 125 hypertensive subjects, without any symptoms of heart failure, the detailed echocardiographic assessment of LV systolic and diastolic function was performed before and after 12 months of hypotensive treatment...

REVIEW
Amy Randell, Noriko Daneshtalab
Elastin microfibril interface-located protein 1 (EMILIN1), a glycoprotein, is associated with elastin in the extracellular matrix (ECM) of arteries, lymph vasculature, and other tissues. EMILIN1 particularly has a niche role in elastin fiber biogenesis (elastogenesis) by aiding with the fusion of elastin fibers, rendering them more ordered. In addition to elastogenesis, EMILIN1 has been shown to have roles in maintenance of vascular cell morphology, smooth muscle cell adhesion to elastic fibers, and transforming growth factor (TGFβ) regulation, by inhibiting TGFβ activation via blocking the proteolytic production of the latency-associated peptide/active TGFβ complex...

The aim of the study was to investigate the association of left ventricular diastolic dysfunction (LVDD) with central and peripheral hemodynamics. A total of 1599 community-based senior residents (aged ≥ 65 years) in northern Shanghai, China, were recruited as of August 2015. Echocardiography was performed for each participant using the MyLab30 Gold CV system. According to the recommendations from the American Society of Echocardiography, the ratio of E (peak early diastolic transmitral flow velocity) to E' (early diastolic lateral mitral annulus velocity) was assessed for the evaluation of LVDD...

REVIEW
Michael A Garfinkle
Essential hypertension is common and is associated with significant morbidity and mortality. However, questions remain as to the exact physiological mechanisms underlying this disease. First, we discuss how essential hypertension may be largely a result of a maladaptation to a high-salt diet and that high blood pressure, rather than being an inactive side effect of high salt intake, may be an adaptive mechanism to improve salt secretion. Next, we explain how any physiological state that reduces urinary sodium concentrating ability may increase an individual's risk for salt-induced hypertension...

This crossover study examined whether acute cardiovascular responses, baroreceptor sensitivity (BRS), and brain oxygenation during isometric exercise are altered after cigarette smoking. Twelve young, habitual smokers randomly performed a smoking and a control protocol, during which participants smoked one cigarette (0.9 mg nicotine) or a sham cigarette, before exercise. Testing involved baseline, a 5-minute smoking, a 10-minute post-smoking rest, 3-minute handgrip exercise (30% maximum voluntary contraction), and recovery...

The aim of this study was to analyze the influence of the number of visits and the number of blood pressure (BP) measurements on the prevalence of high blood pressure (HBP) in adolescents. A cross-sectional epidemiologic study with 481 adolescents (14-19 years old) selected using a random cluster sampling strategy. We measured the BP three times in a first visit. Adolescents with HBP performed subsequent visits. The final calculation of BP followed four strategies: the 1st measure, mean of 1st and 2nd measurements, mean of all three measurements, and averaging the 2nd and 3rd measurements...

Left ventricular hypertrophy has been documented in hypertensive adolescents and among some with prehypertension. Obesity also appears to be associated with cardiac mass, independent of blood pressure (BP). Fibroblast growth factor 23 (FGF23) is a novel biomarker positively associated with left ventricular hypertrophy in adults with and without kidney disease. The aim of this study was to determine if there was a significant and independent association of FGF23 with cardiac mass in a Black American adolescent cohort including both normotensive and prehypertensive participants with and without obesity...

In 2012, the Centers for Medicare & Medicaid Services (CMS) instituted a Physician Quality Reporting System measure for screening and referring patients with elevated blood pressure (BP). The aims of this study were to (1) assess the reliability of ED triage BP as a metric to establish when the CMS threshold (≥120/80 mm Hg), and other clinically relevant BP thresholds (≥140/90 and ≥160/100 mm Hg) have been met, using BP measured with a highly accurate device (BpTRU) in the emergency department as the gold standard; and (2) determine whether correct identification varies by gender, race, or triage acuity...

A decreased aortic-to-brachial pulse pressure (PP) amplification, which is independently associated with cardiovascular outcomes, may index several aortic functional changes. However, that aortic functional change most likely to account for this effect is uncertain. In 706 randomly selected community participants of African ancestry with a mean age of 44.4 ± 18.2 years, we assessed aortic function using radial applanation tonometry and SphygmoCor software (including forward [Pf] and backward [Pb] wave separation analysis assuming a triangular flow waveform) and left ventricular mass index (LVMI) (echocardiography)...

Digital vascular tone and function, as measured by peripheral arterial tonometry (PAT), are associated with cardiovascular risk and events in non-Hispanic whites. There are limited data on relations between PAT and cardiovascular risk in African-Americans. PAT was performed on a subset of Jackson Heart Study participants using a fingertip tonometry device. Resting digital vascular tone was assessed as baseline pulse amplitude. Hyperemic vascular response to 5 minutes of ischemia was expressed as the PAT ratio (hyperemic/baseline amplitude ratio)...

The effect of age to modify the relationship between insulin resistance and hypertension is unclear. In this retrospective, cross-sectional study, median age was used to create two age groups (<52 vs. ≥52 years), and comparisons were made of metabolic characteristics, including steady-state plasma glucose (SSPG) concentrations measured during the insulin suppression test to quantify insulin resistance. Individuals were stratified into SSPG tertiles and categorized as having normal blood pressure (BP), prehypertension, or hypertension...
