Abstract
There are significant healthcare disparities in cardiovascular medicine that represent a challenge for cardiologists and healthcare policy-makers who wish to provide equitable care. Disparities exist in both the management and outcomes of hypertension, coronary artery disease and its sequelae, and heart failure. These disparities are present along the lines of race, gender, and socioeconomic status. Despite recent efforts to reduce disparity, there are knowledge and research gaps among cardiologists with regards to both the scope of the problem and how to solve it. Solutions include increasing awareness of disparities in cardiovascular health, increasing research for optimal treatment of underserved communities, and public policy changes that reduce disparities in social determinants of health.

Abstract
Despite the general consensus that there is no biological basis to race, racial categorization is still used by clinicians to guide diagnosis and treatment plans for certain diseases. In medicine, race is commonly used as a rough proxy for unmeasured social, environmental, and genetic factors. The American College of Cardiology's Eighth Joint National Committee's (JNC 8) guidelines for the treatment of hypertension provide race-specific medication recommendations for Black versus non-Black patients, without strong evidence for race-specific physiological differences in drug response. Clinicians practicing family or geriatric medicine (n = 21) were shown a video of a mock hypertensive patient with genetic ancestry test results that could be viewed as discordant with their phenotype and self-identified race. After viewing the videos, we conducted in-depth interviews to examine how clinicians value and prioritize different cues about race -- namely genetic ancestry data, phenotypic appearance, and self-identified racial classifications - when making treatment decisions in the context of race-specific guidelines, particularly in situations when patients claim mixed-race or complex racial identities. Results indicate that clinicians inconsistently follow the race-specific guidelines for patients whose genetic ancestry test results do not match neatly with their self-identified race or phenotypic features. However, many clinicians also emphasized the importance of clinical experience, side effects, and other factors in their decision making. Clinicians' definitions of race, categorization of the patient's race, and prioritization of racial cues greatly varied. The existence of the race-specific guidelines clearly influences treatment decisions, even as clinicians' express uncertainty about how to incorporate consideration of a patient's genetic ancestry. In light of widespread debate about removal of race from medical diagnostics, researchers should revisit the clinical justification for maintaining these race-specific guidelines. Based on our findings and prior studies indicating a lack of convincing evidence for biological differences by race in medication response, we suggest removing race from the JNC 8 guidelines to avoid risk of perpetuating or exacerbating health disparities in hypertension.

Abstract
The Brain Health crisis stands as one of humankind's most pressing threats, with age-related noncommunicable brain diseases, particularly stroke, and dementia, affecting hundreds of millions annually and jeopardizing the economic well-being of populations worldwide. Epidemiological studies indicate that ≈40% of dementia and 60% of stroke cases are attributable to modifiable risk factors. In this Comments and Opinions article, we underscore the pivotal role of blood pressure (BP) control in reducing suffering, enhancing economic well-being, and promoting healthy longevity for populations worldwide. Emphasizing that BP control is crucial for both brain and heart health, it advocates for heightened awareness, positioning hypertension as a primary focus for preventing dementia and stroke with potential global impact. Despite its significance, BP control encounters global challenges, with proportions of the population maintaining adequately controlled hypertension ranging from 23% to 90%. The World Health Organization estimated that 46% of the 1.28 billion people with hypertension are unaware of their elevated BP. Given the notable disparities in BP management, addressing BP management also contributes to combating significant health inequalities. The next time you are faced with a patient anxious about the prospect of experiencing a fate similar to a parent with dementia or a sister with a stroke, we suggest a straightforward answer for health care providers: start ensuring BP control. BP is a matter of brain health, and it is a matter of our economic future.

Clin Ther 2023; 45:1259-1265. [PMID: 37648574 DOI: 10.1016/j.clinthera.2023.07.026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2023] [Revised: 07/31/2023] [Accepted: 07/31/2023] [Indexed: 09/01/2023]
Abstract
PURPOSE Suboptimal glucose control early in the diagnosis of type 2 diabetes (T2D) is strongly associated with subsequent morbidity and mortality, termed the 'glycaemic legacy'. Additionally, it is known that Asian and Black individuals are at increased risk of T2D, and its associated complications compared to their White counterparts. However, ethnicity does not currently feature in the treatment algorithm of T2D, unlike in other cardiovascular disease states such as hypertension. We therefore sought to evaluate the real-world impact of early intensive treatment with combination therapy on cardiorenal outcomes compared to standard treatment in T2D, with a focus on ethnicity. METHODS We performed a retrospective cohort study of all patients aged 18 or over with T2D using the TriNetX platform. TriNetX is a global collaborative network providing access to real time, anonymised medical records. We included patients who were initiated with Metformin and an SGLT2i within one month of diagnosis of T2D and compared this cohort with individuals who received Metformin only for a period of at least 1 year. We evaluated cardiovascular and renal outcomes at three years and stratified by ethnicity. We excluded individuals with a personal history of an outcome of interest. FINDINGS We identified 49,651 individuals with T2D who were treated with Metformin and an SGLT2i and 1,028,806 patients with T2D who were treated with Metformin alone. A total of 98,094 individuals were included in the core analysis. The Metformin only group had a greater risk of mortality (RR 1.44, [95% CI 1.34-1.55], P<0.0001), CKD (RR 1.10, [95% CI 1.04-1.16], P = 0.0004), diabetic nephropathy (RR 1.06, [95% CI 1.01-1.12], P = 0.0239), heart failure (RR 1.13, [95% CI 1.07-1.21], P < 0.0001) and hospitalisation (RR 1.24, [95% CI 1.21-1.27], P < 0.0001) compared to individuals treated with Metformin and SGLT2i. Black individuals had a reduced risk of mortality (RR 0.71, [95% CI 0.55-0.92], P = 0.0099) and IHD (RR 0.73, [95% CI 0.64-0.84], P < 0.0001) compared to White individuals. Asian individuals had a reduced risk of heart failure (RR 0.61, [95% CI 0.41-0.91], P = 0.0134) and hospitalisation (RR 0.76, [95% CI 0.66-0.87], P = 0.0001) compared to White individuals. IMPLICATIONS Initial combination treatment within the first year of T2D diagnosis confers favourable cardio-metabolic outcomes when compared to standard therapy, even in patients without established cardiovascular disease. Black and Asian individuals in particular demonstrate a greater degree of benefit compared to White individuals. Further prospective studies with a focus on ethnicity are now required to validate these findings.

Abstract
Cardiovascular diseases remain the leading cause of death in the United States. Several studies have shown racial disparities in the cardiovascular outcomes. When compared to their Non-Hispanic White (NHW) counterparts, non-Hispanic Black (NHB) individuals have higher prevalence of cardiovascular risk factors and thus, increased mortality from atherosclerotic cardiovascular diseases. This is evidenced by lower scoring in the indices of the American Heart Association's Life Essential 8 among NHB individuals. NHB individuals score lower in blood pressure, blood lipids, nicotine exposure, sleep, physical activity level, glycemic control, weight, and diet when compared to NHW individuals. Measures to improve these indices at the primary care level may potentially hold the key in mitigating the health care disparities in cardiovascular health experienced by NHB individuals.

Abstract
BACKGROUND Neighborhood disadvantage is associated with a higher risk of sudden cardiac death. However, autopsy findings have never been investigated in this context. Here, we sought to explore associations between neighborhood disadvantage and cardiovascular findings at autopsy in cases of sudden death in the State of Maryland. METHODS State of Maryland investigation reports from 2,278 subjects within the CVPath Sudden Death Registry were screened for street addresses and 9-digit zip codes. Area deprivation index (ADI), used as metric for neighborhood disadvantage, was available for 1,464 subjects; 650 of whom self-identified as Black and 814 as White. The primary study outcome measurements were causes of death and gross and histopathologic findings of the heart. RESULTS Subjects from most disadvantaged neighborhoods (i.e., ADI ≥ 8; n = 607) died at younger age compared with subjects from less disadvantaged neighborhoods (i.e., ADI ≤ 7; n = 857; 46.07 ± 14.10 vs 47.78 ± 13.86 years; P = 0.02) and were more likely Black or women. They were less likely to die from cardiac causes of death (61.8% vs 67.7%; P = 0.02) and had less severe atherosclerotic plaque features, including plaque burden, calcification, intraplaque hemorrhage, and thin-cap fibroatheromas. In addition, subjects from most disadvantaged neighborhoods had lower frequencies of plaque rupture (18.8% vs 25.1%, P = 0.004). However, these associations were omitted after adjustment for traditional risk factors and race. CONCLUSION Neighborhood disadvantage did not associate with cause of death or coronary histopathology after adjustment for cardiovascular risk factors and race, implying that social determinants of health other than neighborhood disadvantage play a more prominent role in sudden cardiac death.

Abstract
PURPOSE OF REVIEW To characterize the barriers and opportunities associated with racial and ethnic disparities in blood pressure (BP) control. RECENT FINDINGS Blood pressure (BP) control rates in the USA have worsened over the last decade, with significantly lower rates of control among people from racial and ethnic minority groups, with non-Hispanic (NH) Black persons having 10% lower control rates compared to NH White counterparts. Many factors contribute to BP control including key social determinants of health (SDoH) such as health literacy, socioeconomic status, and access to healthcare as well as low awareness rates and dietary habits. Numerous pharmacologic and non-pharmacologic interventions have been developed to reduce racial and ethnic disparities in BP control. Among these, dietary programs designed to help reduce salt intake, faith-based interventions, and community-based programs have found success in achieving better BP control among people from racial and ethnic minority groups. Disparities in the prevalence and management of hypertension persist and remain high, particularly among racial and ethnic minority populations. Ongoing efforts are needed to address SDoH along with the unique genetic, social, economic, and cultural diversity within these groups that contribute to ongoing BP management inequalities.

Abstract
Hypertension is the leading cause of cardiovascular morbidity and mortality globally. In the United States, the prevalence of hypertension (blood pressure ≥130/80 mm Hg) among adults is approximately 45%. Racial/ethnic disparities in hypertension prevalence are well documented, especially among Black adults who are disproportionately affected and have one of the highest rates of hypertension globally. Hypertension control remains a persistent public health crisis. Recently published data indicate suboptimal hypertension control rates, particularly for racial/ethnic minority groups in the United States. This requires urgent action because of the significant health care burden from cardiovascular- and stroke-related morbidity and mortality. This clinical review delineates racial/ethnic disparities in the epidemiology of hypertension, and the impact of social determinants of health on the quality of cardiovascular care and outcomes. Clinical practice guideline recommendations and various national programs targeted toward hypertension control and proposed solutions to eliminate these disparities are discussed.

Abstract
Chile has become a popular destination for migrants from South America and the Caribbean (low- and middle-income countries migration). Close to 200.000 Haitian migrants have arrived in Chile. Infectious and non-infectious disease burden among the Haitian adult population living in Chile is unknown. This study aimed to acquire the basic health information (selected transmissible and non-transmissible conditions) of the Haitian adult population living in Chile. A cross-sectional survey was performed, inviting Haitian-born residents in Chile older than 18 years old. Common conditions and risk factors for disease were assessed, as well as selected transmissible conditions (HIV, HBV, and HCV). 498 participants (60.4% female) from 10 communities in two regions of Chile were surveyed. Most subjects had never smoked (91.5%), and 80% drank less than one alcohol unit per month. The mean BMI was 25.6, with 45% of participants having a normal BMI (20-25). Hypertension was present in 31.5% (33% in the 25-44 age group). Prevalence of HIV was 2.4% (95 CI 1.3-4.2%), hepatitis B (HBsAg positive) was 3.4% (95 CI 2.1-5.5%), and hepatitis C was 0% (95 CI 0.0-0.9%). Quality of life showed a significant prevalence of depression and anxiety markers, particularly in those arriving in Chile less than 1 year ago. Low prevalence of obesity, diabetes, smoking, and drinking and estimated cardiovascular risk were found. Nonetheless, hypertension at a younger age, disproportionately higher prevalence of HIV and HBV infection and frequent markers of anxiety and depression were also found. Public policies for detecting and treating hypertension, HIV, and HBV screening, offering HBV vaccination, and organizing mental health programs for Haitian immigrants, are urgently needed.

Cardiorespiratory Fitness and Incident Stroke Types: The FIT (Henry Ford ExercIse Testing) Project. Mayo Clin Proc 2020; 95:1379-1389.

Abstract
OBJECTIVE To study the association between cardiorespiratory fitness (CRF) and incident stroke types. PATIENTS AND METHODS We studied a retrospective cohort of patients referred for treadmill stress testing in the Henry Ford Health System (Henry Ford ExercIse Testing Project) without history of stroke. CRF was expressed by metabolic equivalents of task (METs). Using appropriate International Classification of Diseases, Ninth Revision codes, incident stroke was ascertained through linkage with administrative claims files and classified as ischemic, hemorrhagic, and subarachnoid hemorrhage (SAH). Multivariable-adjusted Cox proportional hazards models examined the association between CRF and incident stroke. RESULTS Among 67,550 patients, mean ± SD age was 54±13 years, 46% (n=31,089) were women, and 64% (n=43,274) were white. After a median follow-up of 5.4 (interquartile range 2.7-8.5) years, a total of 7512 incident strokes occurred (6320 ischemic, 2481 hemorrhagic, and 275 SAH). Overall, there was a graded lower incidence of stroke with higher MET categories. Patients with METs of 12 or more had lower risk of overall stroke [0.42 (95% CI, 0.36-0.49)], ischemic stroke [0.69 (95% CI, 0.58-0.82)], and hemorrhagic stroke [0.71 (95% CI, 0.52-0.95)]. CONCLUSION In a large ethnically diverse cohort of patients referred for treadmill stress testing, CRF is inversely associated with risk for ischemic and hemorrhagic stroke.

Abstract
Patients anticipating surgery and anesthesia often need preoperative care to reduce risk and facilitate services on the day of surgery. Preparing patients often requires extensive evaluation and coordination of care. Vulnerable, marginalized, and disenfranchised populations have special concerns, limitations, and needs. These patients may have unidentified or poorly managed comorbidities. Underrepresented minorities and transgender patients may avoid or have limited access to health care. Homelessness, limited health literacy, and incarceration hinder perioperative optimization initiatives. Identifying patients who will benefit from additional resource allocation and knowledge of their special challenges is vital to reducing disparities in health and health care.

Abstract
Disease risk varies significantly between ethnic groups, however, the clinical significance and implications of these observations are poorly understood. Investigating ethnic differences within the human proteome may shed light on the impact of ancestry on disease risk. We used admixture mapping to explore the impact of genetic ancestry on 237 cardiometabolic biomarkers in 2,216 Latin Americans within the Outcomes Reduction with an Initial Glargine Intervention (ORIGIN) study. We developed a variance component model in order to determine the proportion of variance explained by inter-ancestry differences, and we applied it to the biomarker panel. Multivariable linear regression was used to identify and localize genetic loci affecting biomarker variability between ethnicities. Variance component analysis revealed that 5% of biomarkers were significantly impacted by genetic admixture (p < 0.05/237), including C-peptide, apolipoprotein-E, and intercellular adhesion molecule 1. We also identified 46 regional associations across 40 different biomarkers (p < 1.13 × 10-6). An independent analysis revealed that 34 of these 46 regions were associated at genome-wide significance (p < 5 × 10-8) with their respective biomarker in either Europeans or Latin populations. Additional analyses revealed that an admixture mapping signal associated with increased C-peptide levels was also associated with an increase in diabetes risk (odds ratio [OR] = 6.07 per SD, 95% confidence interval [CI] 1.44 to 25.56, p = 0.01) and surrogate measures of insulin resistance. Our results demonstrate the impact of ancestry on biomarker levels, suggesting that some of the observed differences in disease prevalence have a biological basis, and that reference intervals for those biomarkers should be tailored to ancestry. Specifically, our results point to a strong role of ancestry in insulin resistance and diabetes risk.

Abstract
Objective: As compared to whites, the black population develops hypertension (HTN) at an earlier age, has a greater frequency and severity of HTN, and has poorer control of blood pressure (BP). Traditional practices and treatment efforts have had minor impact on these disparities, with over a 2-fold higher death rate currently for blacks as compared to whites. The University of Mississippi Medical Center (UMC) is located in the southeastern US and the Stroke Belt, which has higher rates of HTN and related diseases as compared to the rest of the country. Methods: We retrospectively analyzed the UMC's Research Data Warehouse, containing >30 million electronic health records from >900,000 patients to determine the initial BP response following the first prescribed antihypertensive drug. Results: There were 5,973 white (45% overall HTN prevalence) and 10,731 black (57% overall HTN prevalence) patients who met criteria for the study. After controlling for age, BMI, and drug dosage, black males were overall less likely to have controlled BP (defined as < 140/90 mmHg) and were associated with smaller falls in BP as compared to whites and black females. Blockers of the renin-angiotensin system (RAS) failed to significantly improve odds of HTN control vs. the untreated group in black patients. However, our data suggests that these drugs do provide significant benefit in blacks when combined with THZ, as compared to untreated and as compared to THZ alone. Conclusion: These data support the use of a single-pill formulation with ARB or ACE inhibitor with a thiazide in blacks for initial first-line HTN therapy and suggests that HTN treatment strategies should consider both race and gender. Our study gives a unique insight into initial antihypertensive responses in actual clinical practice and could have an impact in BP control efficiency in a state with prevalent socioeconomic and racial disparities.

Abstract
Recently updated clinical guidelines have highlighted the gaps in our understanding and management of pediatric hypertension. With increased recognition and diagnosis of pediatric hypertension, the use of antihypertensive agents is also likely to increase. Drug selection to treat hypertension in the pediatric patient population remains challenging. This is primarily due to a lack of large, well-designed pediatric safety and efficacy trials, limited understanding of pharmacokinetics in children, and unknown risk of prolonged exposure to antihypertensive therapies. With newer legislation providing financial incentives for conducting clinical trials in children, along with publication of pediatric-focused guidelines, literature available for antihypertensive agents in pediatrics has increased over the last 20 years. The objective of this article is to review the literature for safety and efficacy of commonly prescribed antihypertensive agents in pediatrics. Thus far, the most data to support use in children was found for angiotensin-converting enzyme inhibitors (ACE-I), angiotensin receptor blockers (ARB), and calcium channel blockers (CCB). Several gaps were noted in the literature, particularly for beta blockers, vasodilators, and the long-term safety profile of antihypertensive agents in children. Further clinical trials are needed to guide safe and effective prescribing in the pediatric population.

Abstract
Race and ancestry have long been associated with differential risk and outcomes to disease as well as responses to medications. These differences in drug response are multifactorial with some portion associated with genomic variation. The field of pharmacogenomics aims to predict drug response in patients prior to medication administration and to uncover the biological underpinnings of drug response. The field of human genetics has long recognized that genetic variation differs in frequency between ancestral populations, with some single nucleotide polymorphisms found solely in one population. Thus far, most pharmacogenomic studies have focused on individuals of European and East Asian ancestry, resulting in a substantial disparity in the clinical utility of genetic prediction for drug response in US minority populations. In this review, we discuss the genetic factors that underlie variability to drug response and known pharmacogenomic associations and how these differ between populations, with an emphasis on the current knowledge in cardiovascular pharmacogenomics.

Abstract
OBJECTIVES Previous studies have suggested that hypertension in HIV-positive individuals is associated primarily with traditional risk factors such as older age, diabetes and dyslipidaemia. However, controversy remains as to whether exposure to antiretroviral (ARV) drugs poses additional risk, and we investigated this question in the Data Collection on Adverse Events of Anti-HIV Drugs (D:A:D) cohort. METHODS The incidence of hypertension [systolic blood pressure (BP) > 140 and/or diastolic BP > 90 mmHg and/or initiation of antihypertensive treatment] was determined overall and in strata defined by demographic, metabolic and HIV-related factors, including cumulative exposure to each individual ARV drug. Predictors of hypertension were identified using uni- and multivariable Poisson regression models. RESULTS Of 33 278 included persons, 7636 (22.9%) developed hypertension over 223 149 person-years (PY) [incidence rate: 3.42 (95% confidence interval (CI) 3.35-3.50) per 100 PY]. In univariable analyses, cumulative exposure to most ARV drugs was associated with an increased risk of hypertension. After adjustment for demographic, metabolic and HIV-related factors, only associations for nevirapine [rate ratio 1.07 (95% CI: 1.04-1.13) per 5 years] and indinavir/ritonavir [rate ratio 1.12 (95% CI: 1.04-1.20) per 5 years] remained statistically significant, although effects were small. The strongest independent predictors of hypertension were male gender, older age, black African ethnicity, diabetes, dyslipidaemia, use of lipid-lowering drugs, high body mass index (BMI), renal impairment and a low CD4 count. CONCLUSIONS We did not find evidence for any strong independent association between exposure to any of the individual ARV drugs and the risk of hypertension. Findings provide reassurance that screening policies and preventative measures for hypertension in HIV-positive persons should follow algorithms used for the general population.

Abstract
INTRODUCTION There is paucity of data related to potential gender differences in the use of interventions to prevent and treat cardiovascular disease (CVD) among HIV-positive individuals. We investigated whether such differences exist in the observational D:A:D cohort study. METHODS Participants were followed from study enrolment until the earliest of death, six months after last visit or February 1, 2015. Initiation of CVD interventions [lipid-lowering drugs (LLDs), angiotensin-converting enzyme inhibitors (ACEIs), anti-hypertensives, invasive cardiovascular procedures (ICPs) were investigated and Poisson regression models calculated whether rates were lower among women than men, adjusting for potential confounders. RESULTS Women (n = 12,955) were generally at lower CVD risk than men (n = 36,094). Overall, initiation rates of CVD interventions were lower in women than men; LLDs: incidence rate 1.28 [1.21, 1.35] vs. 2.40 [2.34, 2.46]; ACEIs: 0.88 [0.82, 0.93] vs. 1.43 [1.39, 1.48]; anti-hypertensives: 1.40 [1.33, 1.47] vs. 1.72 [1.68, 1.77] and ICPs: 0.08 [0.06, 0.10] vs. 0.30 [0.28, 0.32], and this was also true for most CVD interventions when exclusively considering periods of follow-up for which individuals were at high CVD risk. In fully adjusted models, women were less likely to receive CVD interventions than men (LLDs: relative rate 0.83 [0.78, 0.88]; ACEIs: 0.93 [0.86, 1.01]; ICPs: 0.54 [0.43, 0.68]), except for the receipt of anti-hypertensives (1.17 [1.10, 1.25]). CONCLUSION The use of most CVD interventions was lower among women than men. Interventions are needed to ensure that all HIV-positive persons, particularly women, are appropriately monitored for CVD and, if required, receive appropriate CVD interventions.

Abstract
Black adults have a higher risk of hypertension compared with non-Hispanic white (NHW) adults, but physiological mechanisms underlying this predisposition remain unclear. This study compared muscle sympathetic nerve activity (MSNA) responses to mental stress in a group of young black and NHW participants. We hypothesized that the sympathoexcitation associated with mental stress would be greater in black adults compared with NHW participants. Thirty-five male adults (19 black, 23 ± 1 yr; 16 NHW, 22 ± 1 yr) were examined during 5-min supine baseline and 5 min of mental stress (via mental arithmetic). Baseline mean arterial pressure (80 ± 2 vs. 82 ± 1 mmHg), heart rate (61 ± 4 vs. 61 ± 2 beats/min), MSNA (13 ± 1 vs. 15 ± 2 bursts/min), and sympathetic baroreflex sensitivity (-1.1 ± 0.4 vs. -1.5 ± 0.3 bursts·100 heart beats-1·mmHg-1) were not significantly different between NHW and black adults ( P > 0.05), respectively. MSNA reactivity to mental stress was significantly higher in NHW compared with black adults (time × race, P = 0.006), with a particularly divergent responsiveness during the first minute of mental stress in NHW (Δ4 ± 1 burst/min) and black (Δ-2 ± 2 burst/min; P = 0.022) men. Blood pressure and heart rate reactivity to mental stress were similar between groups. In summary, black participants demonstrated a lower MSNA responsiveness to mental stress compared with NHW adults. These findings suggest that, despite a higher prevalence of hypertension, black subjects do not appear to have higher neural and cardiovascular responsiveness to mental stress compared with NHW. NEW & NOTEWORTHY Black men have a blunted muscle sympathetic nerve activity response to mental stress compared with non-Hispanic white (NHW) men, especially at the onset of mental stress when muscle sympathetic nerve activity decreased in blacks and increased in NHW men. Thus, despite a high prevalence of hypertension in blacks, normotensive NHW men display a greater peripheral sympathetic neural reactivity to mental stress than black men.

Abstract
Compared with persons of European descent (ED), persons of African descent (AD) have lower aldosterone (ALDO) levels, with the assumption being that the increased cardiovascular disease (CVD) risk associated with AD is not related to ALDO. However, the appropriateness of the ALDO levels for the volume status in AD is unclear. We hypothesized that, even though ALDO levels are lower in AD, they are inappropriately increased, and therefore, ALDO could mediate the increased CVD in AD. To test this hypothesis, we analyzed data from HyperPATH - 1,788 individuals from the total cohort and 765 restricted to ED-to-AD in a 2:1 match and genotyped for the endothelin-1 gene (EDN1). Linear regression analyses with adjustments were performed. In the total and restricted cohorts, PRA, ALDO, and urinary potassium levels were significantly lower in AD. However, in the AD group, greater ALDO dysregulation was present as evidenced by higher ALDO/plasma renin activity (PRA) ratios (ARR) and sodium-modulated ALDO suppression-to-stimulation indices. Furthermore, EDN1 minor allele carriers had significantly greater ARRs than noncarriers but only in the AD group. ARR levels were modulated by a significant interaction between EDN1 and AD. Thus, EDN1 variants may identify particularly susceptible ADs who will be responsive to treatment targeting ALDO-dependent pathways (e.g., mineralocorticoid-receptor antagonists).

Abstract
Background—
A key to reduce and eradicate racial disparities in hypertension outcomes is to understand their causes. We aimed at evaluating racial differences in antihypertensive drug utilization patterns and blood pressure control by insurance status, age, sex, and presence of comorbidities.
Methods and Results—
A total of 8796 hypertensive individuals ≥18 years of age were identified from the National Health and Nutrition Examination Survey (2003–2012) in a repeated cross-sectional study. During the study period, all 3 racial groups (whites, blacks, and Hispanics) experienced substantial increase in hypertension treatment and control. The overall treatment rates were 73.9% (95% confidence interval [CI], 71.6%–76.2%), 70.8% (95% CI, 68.6%–73.0%), and 60.7% (95% CI, 57.0%–64.3%) and hypertension control rates were 42.9% (95% CI, 40.5%–45.2%), 36.9% (95% CI, 34.7%–39.2%), and 31.2% (95% CI, 28.6%–33.9%) for whites, blacks, and Hispanics, respectively. When stratified by insurance status, blacks (odds ratio, 0.74 [95% CI, 0.64–0.86] for insured and 0.59 [95% CI, 0.36–0.94] for uninsured) and Hispanics (odds ratio, 0.74 [95% CI, 0.60–0.91] for insured and 0.58 [95% CI, 0.36–0.94] for uninsured) persistently had lower rates of hypertension control compared with whites. Racial disparities also persisted in subgroups stratified by age (≥60 and <60 years of age) and presence of comorbidities but worsened among patients <60 years of age.
Conclusions—
Black and Hispanic patients had poorer hypertension control compared with whites, and these differences were more pronounced in younger and uninsured patients. Although black patients received more intensive antihypertensive therapy, Hispanics were undertreated. Future studies should further explore all aspects of these disparities to improve cardiovascular outcomes.

Abstract
UNLABELLED African Americans (AA) have increased carotid artery intima-media thickness and decreased vascular function compared with their Caucasian (CA) peers. Aerobic exercise prevents and potentially reverses arterial dysfunction. PURPOSE The purpose of this study was to examine the effect of 8 wk of moderate- to high-intensity aerobic training in young healthy sedentary AA and CA men and women. METHODS Sixty-four healthy volunteers (men, 28; women, 36) with mean age 24 yr underwent measures of arterial structure, function, and blood pressure (BP) variables at baseline, after the 4-wk control period, and 8 wk after training. RESULTS There was a significant increase in VO2peak among both groups after exercise training. Brachial systolic BP decreased significantly after the control period in both groups but not after exercise training. Carotid pulse pressure decreased significantly in both groups after exercise training as compared with that in baseline. There was no change in any of the other BP variables. AA had higher intima-media thickness at baseline and after the control period but it significantly decreased after exercise training compared with that of CA. AA had significantly lower baseline forearm blood flow and reactive hyperemia compared with those of CA, but exercise training had no effect on these variables. There was no significant difference in arterial stiffness (central pulse wave velocity) and wave-reflection (augmentation index) between the two groups at any time point. CONCLUSIONS This is the first study to show that 8 wk of aerobic exercise training causes significant improvement in the arterial structure in young, healthy AA, making it comparable with the CA and with minimal effects on BP variables.

Abstract
Background: Hypertension is a common medical disease, occurring in about one third of young adults and almost two thirds of individuals over the age of 60. With the release of the Eighth Joint National Committee on Prevention, Detection, Evaluation, and Treatment (JNC-8) guidelines, there have been major changes in blood pressure management in the various subgroups. Aim: Optimal blood pressure management and markers of end-organ damage in African-American adult patients were compared between patients who were managed according to the JNC-8 hypertension management guidelines and those who were treated with other regimens. Materials and Methods: African-American patients aged 18 years or older with an established diagnosis of hypertension were included in the study who were followed up in our internal medicine clinic between January 1, 2013 and December 31, 2103; the data on their systolic and diastolic blood pressure readings, heart rate, body mass index (BMI), age, gender, comorbidities, and medications were recorded. Patients were divided into four groups based on the antihypertensive therapy as follows — Group 1: Diuretic only; Group 2: Calcium channel blocker (CCB) only; Group 3: Diuretic and CCB; Group 4: Other antihypertensive agent. Their blood pressure control, comorbidities, and associated target organ damage were analyzed. Results: In all 323 patients, blood pressures were optimally controlled. The majority of the patients (79.6%) were treated with either a diuretic, a CCB, or both. Intergroup comparison analysis showed no statistically significant difference in the mean systolic blood pressure, mean diastolic blood pressure, associated comorbidities, or frequency of target organ damage. Conclusion: Although diuretics or CCBs are recommended as first-line agents in African-American patients, we found no significant difference in the optimal control of blood pressure and frequency of end-organ damage compared to management with other agents.

Abstract
Little is known about the effective dose of motivational interviewing for maintaining intervention-induced health outcome improvements. The purpose of this study was to compare effects of two doses of motivational interviewing for maintaining blood pressure improvements in a community-engaged lifestyle intervention conducted with African-Americans. Participants were tracked through a 12-month maintenance phase following a 6-month intervention targeting physical activity and diet. For the maintenance phase, participants were randomized to receive a low (4) or high (10) dose of motivational interviewing delivered via telephone by trained research staff. Generalized linear models were used to test for group differences in blood pressure. Blood pressure significantly increased during the maintenance phase. No differences were apparent between randomized groups. Results suggest that 10 or fewer motivational interviewing calls over a 12-month period may be insufficient to maintain post-intervention improvements in blood pressure. Further research is needed to determine optimal strategies for maintaining changes.

Effects of Lifestyle Modification on Telomerase Gene Expression in Hypertensive Patients: A Pilot Trial of Stress Reduction and Health Education Programs in African Americans.

Abstract
BACKGROUND African Americans suffer from disproportionately high rates of hypertension and cardiovascular disease. Psychosocial stress, lifestyle and telomere dysfunction contribute to the pathogenesis of hypertension and cardiovascular disease. This study evaluated effects of stress reduction and lifestyle modification on blood pressure, telomerase gene expression and lifestyle factors in African Americans. METHODS Forty-eight African American men and women with stage I hypertension who participated in a larger randomized controlled trial volunteered for this substudy. These subjects participated in either stress reduction with the Transcendental Meditation technique and a basic health education course (SR) or an extensive health education program (EHE) for 16 weeks. Primary outcomes were telomerase gene expression (hTERT and hTR) and clinic blood pressure. Secondary outcomes included lifestyle-related factors. Data were analyzed for within-group and between-group changes. RESULTS Both groups showed increases in the two measures of telomerase gene expression, hTR mRNA levels (SR: p< 0.001; EHE: p< 0.001) and hTERT mRNA levels (SR: p = 0.055; EHE: p< 0.002). However, no statistically significant between-group changes were observed. Both groups showed reductions in systolic BP. Adjusted changes were SR = -5.7 mm Hg, p< 0.01; EHE = -9.0 mm Hg, p < 0.001 with no statistically significant difference between group difference. There was a significant reduction in diastolic BP in the EHE group (-5.3 mm Hg, p< 0.001) but not in SR (-1.2 mm Hg, p = 0.42); the between-group difference was significant (p = 0.04). The EHE group showed a greater number of changes in lifestyle behaviors. CONCLUSION In this pilot trial, both stress reduction (Transcendental Meditation technique plus health education) and extensive health education groups demonstrated increased telomerase gene expression and reduced BP. The association between increased telomerase gene expression and reduced BP observed in this high-risk population suggest hypotheses that telomerase gene expression may either be a biomarker for reduced BP or a mechanism by which stress reduction and lifestyle modification reduces BP.

Abstract
After nearly a decade of genome-wide association studies, no assessment has yet been made of their contribution toward an explanation of the most prominent racial health disparities observed at the population level. We examined populations of African and European ancestry and focused on cardiovascular diseases, which are collectively the largest contributor to the racial mortality gap. We conducted a systematic search for review articles and meta-analyses published in 2007-2013 in which genetic data from both populations were available. We identified 68 articles relevant to this question; however, few reported significant associations in both racial groups, with just 3 variants meeting study-specific significance criteria. For most outcomes, there were too few estimates for quantitative summarization, but when summarization was possible, racial group did not contribute to heterogeneity. Most associations reported from genome-wide searches were small, difficult to replicate, and in no consistent direction that favored one racial group or another. Although the substantial investment in this technology might have produced clinical advances, it has thus far made little or no contribution to our understanding of population-level racial health disparities in cardiovascular disease.

Abstract
BACKGROUND There have been no studies examining the association between antihypertensive medications and progression of diastolic dysfunction. The purpose of this study is to determine whether there is an association between class of antihypertensive medication and diastolic dysfunction progression in an African American population. METHODS A retrospective cohort study of African American patients with at least two echocardiograms demonstrating diastolic dysfunction drawn from an echocardiogram database at an academic medical center. The main outcome measures were change in diastolic function grade as a function of time and association with hypertension medication classification. RESULTS There were 96 African American patients in the database with 2 or more echocardiograms demonstrating diastolic dysfunction; representing 302 echocardiograms. The mean time between echocardiograms was 2.6 years. The mean age was 64.2 (±10.1) years, 78 % were women, and mean BMI 31.2 (±7.4) kg/m(2). The majority of subjects had Grade I diastolic dysfunction at their initial examination [N = 87 (90.6 %)]. Approximately 22.9 % (n = 22) of the study cohort demonstrated diastolic dysfunction progression. In multivariate analysis use of calcium channel blockers (CCB) was protective against diastolic dysfunction progression (OR for CCB users vs. non-users 0.28, 95 % confidence interval, 0.09-0.90, p < 0.05). CONCLUSIONS These findings suggest that use of calcium channel blockers may have a protective effect against progression of diastolic dysfunction among African American patients. Further studies are required to confirm these findings and identify specific factors that can mediate disease progression among African American individuals with hypertension, who face substantial risk of complications such as diastolic heart failure.

Abstract
The role of antihypertensive therapy in reducing the risk of cardiovascular complications such as heart failure is well established, but the effects of different blood pressure goals on patient-perceived health status has not been well defined. We sought to determine if adverse effects on perceived health status will occur with lower blood pressure goals or more intensive antihypertensive therapy. Data were prospectively collected as a part of a single center, randomized controlled trial designed to evaluate standard (Seventh Joint National Committee on Prevention, Detection, Evaluation and Treatment of High Blood Pressure-compliant) versus intense (<120/80 mm Hg) blood pressure goals for patients with uncontrolled hypertension and subclinical hypertensive heart disease. Blood pressure management was open label, and health status was measured at 3-month intervals over 1 year of follow-up using the short-form (SF)-36. Mixed linear models were constructed for each of the SF-36 summary scores. One hundred twenty-three (mean age 49.4 ± 8.2; 65% female; 95.1% African American) patients were randomized, 88 of whom completed the protocol. With the exception of a decrease in perceived health transition, health status did not change significantly on repeat measurement. Lower blood pressure goals and more intensive antihypertensive therapy appear to be well tolerated with limited effects on patients' perception of health status.

Abstract
OBJECTIVE Discrimination is posited to underlie racial disparities in hypertension. Extant literature suggests a possible association between racial discrimination and blood pressure, although inconsistent findings have been reported. The aim of this comprehensive systematic review was to quantitatively evaluate the association between perceived racial discrimination with hypertensive status and systolic, diastolic, and ambulatory blood pressure. METHOD Electronic database search of PubMed and PsycINFO (keywords: blood pressure/hypertension/diastolic/systolic, racism/discrimination/prejudice/unfair treatment) was combined with descendancy and ascendancy approaches. Forty-four articles (N = 32,651) met inclusion criteria. Articles were coded for demographics, hypertensive diagnosis, blood pressure measurement, discrimination measure and constructs, study quality, and effect sizes. RESULTS Random effects meta-analytic models were tested based on Fisher's Z, the derived common effect size metric. Overall, perceived racial discrimination was associated with hypertensive status, Zhypertension = 0.048, 95% CI [.013, .087], but not with resting blood pressure, Zsystolic = 0.011, 95% CI [-.006, .031], Zdiastolic = .016, 95% CI [-.006, .034]. Moderators that strengthened the relation included sex (male), race (Black), age (older), education (lower), and hypertensive status. Perceived discrimination was most strongly associated with nighttime ambulatory blood pressure, especially among Blacks. CONCLUSIONS Despite methodological limitations in the existing literature, there was a small, significant association between perceived discrimination and hypertension. Future studies should consider ambulatory nighttime blood pressure, which may more accurately capture daily variation attributable to experienced racial discrimination. Perceived discrimination may partly explain racial health disparities.

Abstract
Hypertension treatment regimens used by African American adults in the Jackson Heart Study were evaluated at the first two clinical examinations (2415 treated hypertensive persons at examination I [exam I], 2000-2004; 2577 at examination II [exam II], 2005-2008). Blood pressure (BP) was below 140/90 mm Hg for 66% and 70% of treated participants at exam I and exam II, respectively. The Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure treatment targets were met for 56% and 61% at exam I and exam II, respectively. Persons with diabetes or chronic kidney disease were less likely to have BP at target, as were men compared with women. Thiazide diuretics were the most commonly used antihypertensive medication, and persons taking a thiazide were more likely to have their BP controlled than persons not taking them; thiazides were used significantly less among men than women. Although calcium channel blockers are often considered to be effective monotherapy for African Americans, persons using calcium channel blocker monotherapy were significantly less likely to be at target BP than persons using thiazide monotherapy.

Abstract
Background. Evidence suggests that insufficient sleep duration is associated with an increased likelihood for hypertension. Both short (<6 hours) and long (>8 hour) sleep durations as well as hypertension are more prevalent among blacks than among whites. This study examined associations between sleep duration and hypertension, considering differential effects of race and ethnicity among black and white Americans. Methods. Data came from a cross-sectional household interview with 25,352 Americans (age range: 18-85 years). Results. Both white and black short sleepers had a greater likelihood of reporting hypertension than those who reported sleeping 6 to 8 hours. Unadjusted logistic regression analysis exploring the race/ethnicity interactions between insufficient sleep and hypertension indicated that black short (<6 hours) and long (>8 hours) sleepers were more likely to report hypertension than their white counterparts (OR = 1.34 and 1.37, resp.; P < 0.01). Significant interactions of insufficient sleep with race/ethnicity were observed even after adjusting to effects of age, sex, income, education, body mass index, alcohol use, smoking, emotional distress, diabetes, coronary heart disease, and stroke. Conclusion. Results suggest that the race/ethnicity interaction is a significant mediator in the relationship between insufficient sleep and likelihood of having a diagnosis of hypertension.

Abstract
BACKGROUND Although awareness of hypertension in Black patients has increased, blood pressure (BP) is frequently inadequately controlled. OBJECTIVE This prespecified subgroup analysis of the TRINITY study evaluated the efficacy and safety of olmesartan medoxomil (OM) 40 mg, amlodipine besylate (AML) 10 mg, and hydrochlorothiazide (HCTZ) 25 mg triple-combination treatment compared with the component dual-combination treatments in Black and non-Black study participants. STUDY DESIGN TRINITY was a 12-week, randomized, double-blind, parallel-group evaluation. The first patient was enrolled in May 2008 and the last patient completed the study in February 2009. The study consisted of a 3-week washout period for participants receiving antihypertensive therapy and a 12-week double-blind treatment period. For the treatment phase, all study participants were stratified by age, race, and diabetes mellitus status and randomized to a treatment sequence that led to their final treatment assignment, which they received from weeks 4 to 12 (OM 40 mg/AML 10 mg/HCTZ 25 mg, OM 40 mg/AML 10 mg, OM 40 mg/HCTZ 25 mg, or AML 10 mg/HCTZ 25 mg). In the first 2 weeks of the double-blind treatment period, all participants received either dual-combination treatment or placebo. Participants assigned to dual-combination treatment continued treatment until week 4, and participants receiving placebo were switched at week 2 to receive one of the dual-combination treatments until week 4. At week 4, participants either continued dual-combination treatment or randomly received triple-combination treatment until week 12. SETTING 317 clinical sites in the USA and Puerto Rico were included in the study. PATIENTS Study participants eligible for randomization (N = 2492) were ≥18 years of age with mean seated blood pressure (SeBP) ≥140/100 mmHg or ≥160/90 mmHg (off antihypertensive medication). INTERVENTION The intervention was with dual- or triple-combination antihypertensive treatment: OM 40 mg/AML 10 mg/HCTZ 25 mg, OM 40 mg/AML 10 mg, OM 40 mg/HCTZ 25 mg, or AML 10 mg/HCTZ 25 mg. MAIN OUTCOME MEASURE The primary efficacy variable was the change in least squares (LS) mean seated diastolic BP (SeDBP) from baseline to week 12. Secondary efficacy variables included the LS mean change in seated systolic BP (SeSBP), percentage of study participants reaching BP goal, and safety parameters. RESULTS In both Black and non-Black participants, triple-combination treatment resulted in significant and similar mean reductions in SeDBP and SeSBP (p ≤ 0.0001 vs each dual-combination treatment) with a greater proportion of participants reaching BP goal compared with dual-combination treatments, regardless of race. Most treatment-emergent adverse events were mild or moderate in severity and no new safety concerns were identified. CONCLUSION Triple-combination treatment provided greater BP reductions than dual-combination treatments regardless of race. CLINICAL TRIAL REGISTRATION Registered at ClinicalTrials.gov as NCT00649389.

Abstract
INTRODUCTION Hypertension is a leading risk factor for development of heart failure, stroke and renal disease in the elderly. OBJECTIVE The objective of this study was to evaluate, by means of a prespecified secondary analysis of a 12-week, open-label, single-arm, dose-titration study, the blood pressure (BP)-lowering efficacy and safety of an olmesartan medoxomil (OM)/hydrochlorothiazide (HCTZ)-based titration regimen in patients aged ≥65 years with hypertension. Subgroups were stratified by age (≥65 to ≤75 or >75 years), sex (male or female) and race (Black or non-Black). METHODS Following a 2- to 3-week placebo run-in phase, patients received OM 20 mg, uptitrated to OM 40 mg, followed by addition of HCTZ 12.5-25 mg step-wise at 3-week intervals if seated cuff BP (SeBP) was ≥120/70 mmHg. Patients below this target SeBP were maintained at their current dose but uptitrated to the next consecutive dose if mean seated cuff systolic BP (SBP) was ≥140 mmHg and/or mean seated cuff diastolic BP was ≥90 mmHg at follow-up visits. Efficacy was assessed by 24-hour ambulatory BP monitoring (ABPM) and SeBP measurements. The primary efficacy variable was the change from baseline in mean 24-hour ambulatory SBP after 12 weeks. Secondary efficacy endpoints included the change from baseline in mean 24-hour ambulatory SBP; change from baseline in ambulatory BP during the daytime (8:00 am-4:00 pm), nighttime (10:00 pm-6:00 am) and the last 6, 4 and 2 hours of the dosing interval; change from baseline in SeBP at each titration step and at study end; and the proportion of patients achieving mean 24-hour ambulatory BP targets and SeBP goals at week 12. The frequency and severity of treatment-emergent adverse events (TEAEs) were also documented. RESULTS Baseline and week 12 ABPM data were available for 150 out of 178patients who entered the active treatment phase. Changes from baseline in mean 24-hour ambulatory BP were -26.0/-12.5 mmHg and -24.9/-12.0 mmHg in patients aged ≥65 to ≤75 years (n = 128) and >75 years (n = 48), respectively (all p < 0.0001 vs baseline). Changes from baseline in mean 24-hour ambulatory BP were -26.0/-13.0 mmHg and -25.4/-11.5 mmHg in male (n = 92) and female (n = 84) patients, respectively (all p < 0.0001 vs baseline) and -26.7/-11.8 mmHg and -25.6/-12.4 mmHg in Black (n = 28) and non-Black (n = 148) patients, respectively (all p < 0.0001 vs baseline). Clinically significant ambulatory BP reductions were observed during the daytime, nighttime and the last 6, 4 and 2 hours of the dosing interval in all subgroups. Changes from baseline at week 12 in mean SeBP were similar to 24-hour ambulatory BP changes reported previously. At week 12, the proportion of patients achieving the 24-hour ambulatory BP target of <130/80 mmHg ranged from 67.5% to 77.4% and achieving the SeBP goal of <140/90 mmHg ranged from 60.7% to 68.8% across the subgroups. Most TEAEs and drug-related TEAEs were mild or moderate in severity, and there were no trends across subgroups. CONCLUSIONS In a subgroup analysis based upon age, sex and race in patients aged ≥65 years with hypertension, an OM/HCTZ-based algorithm was efficacious and well tolerated.

Abstract
OBJECTIVE To test whether a synonymous single nucleotide polymorphism (A→G; rs700518) in the CYP19A1 gene, which encodes the enzyme aromatase, is associated with an increased risk for hypertension of midlife women. METHODS In a cross-sectional study, 639 midlife women were recruited. Eligible women had their blood pressure, weight and height measured, and donated a blood sample for hormone and genetic analyses. The participants also completed a detailed study survey. Women were grouped according to their genotype, blood pressure measurements, and medical history. The data were analyzed using logistic and linear regression models. The study had 80% power to detect small differences in mean systolic blood pressure (SBP; 4.5 mmHg) and diastolic blood pressure (DBP; 3 mmHg). RESULTS The selected polymorphism was significantly associated with hypertension and SBP in unadjusted analyses. Interestingly, women with hypertension were more likely to be homozygous for the A allele (AA) compared to women who were not categorized as having hypertension. Further, the mean SBP was significantly higher for women who were homozygous for the A allele when compared to women carrying the other genotypes (AG or GG). The unadjusted association between DBP values and genotype was of borderline statistical significance (p=0.07). However, after adjustment for potential confounders (age, race, body mass index (BMI), smoking and physical activity), the associations between genotype and hypertension/blood pressure were attenuated and not statistically significant. CONCLUSION The rs700518 polymorphism in the CYP19A1 is not associated with hypertension in our sample of midlife women. Other factors, including race and BMI, appear to play a greater role.

Abstract
OBJECTIVES Added-risk hypertensive patients with co-morbidities such as diabetes and metabolic syndrome often require two or more antihypertensives to achieve blood pressure (BP) targets. The aim of this sub-analysis was to determine the efficacy and safety of telmisartan 40 or 80 mg plus amlodipine 5 or 10 mg in patients with hypertension, stratified according to certain criteria such as type 2 diabetes mellitus and metabolic syndrome. METHODS Patients were treated for 8 weeks with telmisartan 20-80 mg plus amlodipine 2.5-10 mg. This post-hoc analysis included patients treated with higher doses, and stratified according to a number of sub-populations (age, race, diabetes, obesity, metabolic syndrome, elevated baseline systolic BP (SBP), renal impairment). RESULTS Eight weeks' treatment with telmisartan plus amlodipine combinations provided consistent reductions in mean SBP/diastolic BP (DBP) across the different sub-populations, similar to the overall population. SBP/DBP reductions ranged from -13.5 to -34.7/-12.6 to -26.1 mmHg and BP goal rates (<140/90 mmHg) ranged from 29.8-100% for the four key dose combinations of telmisartan plus amlodipine. For the highest dose combination of telmisartan 80 mg plus amlodipine 10 mg, SBP/DBP reduction ranged from -19.1 to -34.7/-16.4 to -22.8 mmHg and goal attainment rate from 66.7% to 87.0%. Across the sub-populations, high SBP and DBP response rates were seen with combination treatment (83.3-97.7% and 75.0-95.7%, respectively, with telmisartan 80 mg plus amlodipine 10 mg). The combination was safe and well tolerated across all sub-populations and the incidence of peripheral oedema with telmisartan 40-80 mg plus amlodipine 10 mg was generally lower than with A10 monotherapy. CONCLUSIONS Despite small patient numbers in some sub-populations and the post-hoc nature of the analysis, this does show that the combination of telmisartan plus amlodipine provides an effective, safe and well-tolerated antihypertensive treatment for added-risk hypertensive patients.

Abstract
The renin-angiotensin system (RAS) is a common link between hypertension and comorbidities of obesity and metabolic syndrome (MetS). We evaluated the antihypertensive efficacy and safety of the combination direct renin inhibitor, aliskiren, with amlodipine versus amlodipine alone in self-identified African Americans with stage 2 hypertension in a subgroup of patients with obesity or MetS participating in the Aliskiren Amlodipine Combination in African AmEricans with Stage 2 HypertenSion (AACESS) trial. Subjects, newly diagnosed and treatment naive or taking three or fewer antihypertensive drugs with a mean sitting systolic blood pressure (msSBP) of 160-199 mm Hg were randomized to receive aliskiren/amlodipine 150/5 mg or amlodipine 5 mg for 1 week; force-titrated to aliskiren/amlodipine 300/10 mg or amlodipine 10 mg, for an additional 7 weeks. Overall, 292 obese (body mass index ≥30 kg/m(2)) and 197 MetS subjects had baseline msSBP ranging from 167.0 to 167.5 mm Hg. Least-square mean reductions from baseline to 8 weeks in msSBP, the primary efficacy variable, were significantly higher with aliskiren/amlodipine than with amlodipine in both obese (-33.7 mm Hg vs. -27.9 mm Hg; P < .001) and MetS subjects (-36.4 mm Hg vs. -28.5 mm Hg; P < .001). Both treatments were well tolerated. Aliskiren/amlodipine 300/10 mg is more effective than amlodipine 10 mg in African Americans with stage 2 hypertension and obesity or MetS.

Abstract
Hypertension (HTN) is the most common co-morbidity in the world, and its sequelae, heart failure (HF) is one of most common causes of mortality and morbidity in the world. Current understanding of pathophysiology and management of HTN in HF is mainly based on studies, which have mainly included whites. Among racial groups, African-American adults have the highest rates (44%) of hypertension in the world and are more resistant to treatment. There is an emerging consensus on the significance of racial disparities in the pathophysiology and treatment options of hypertension and heart failure. However, African Americans had been underrepresented in all the trials until the initiation of the A-HEFT trial. Since the recognition of obstructive sleep apnea (OSA) as an important medical condition, large clinical trials have shown benefits of OSA treatment among patients with HTN and HF. This paper focuses on the pathophysiology, causes of secondary hypertension, and treatment of hypertension among African-American patients with heart failure. There is increasing need for randomized clinical trials testing innovative treatment options for African-American patients.

Abstract
Obesity is a biological risk factor or comorbidity that has not received much attention from scientists studying hypertension among African American men. The purpose of this study was to examine the relationship between weight status and high blood pressure among African American men with few economic resources. The authors used surveillance data collected from low-income adults attending community- and faith-based primary care clinics in West Tennessee to estimate pooled and group-specific regression models of high blood pressure. The results from group-specific logistic regression models indicate that the factors associated with hypertension varied considerably by weight status. This study provides a glimpse into the complex relationship between weight status and high blood pressure status among African American men. Additional research is needed to identify mechanisms through which excess weight affects the development and progression of high blood pressure.
