Arterial hypertension.
Brouwers, S, Sudano, I, Kokubo, Y, Sulaica, EM
Lancet (London, England). 2021;(10296):249-261
Abstract
Arterial hypertension is the most important contributor to the global burden of disease; however, disease control remains poor. Although the diagnosis of hypertension is still based on office blood pressure, confirmation with out-of-office blood pressure measurements (ie, ambulatory or home monitoring) is strongly recommended. The definition of hypertension differs throughout various guidelines, but the indications for antihypertensive therapy are relatively similar. Lifestyle adaptation is absolutely key in non-pharmacological treatment. Pharmacologically, angiotensin-converting enzyme inhibitors or angiotensin receptor blockers, calcium channel blockers, and diuretics are the first-line agents, with advice for the use of single-pill combination therapy by most guidelines. As a fourth-line agent, spironolactone should be considered. The rapidly evolving field of device-based therapy, especially renal denervation, will further broaden therapeutic options. Despite being a largely controllable condition, the actual rates of awareness, treatment, and control of hypertension are disappointingly low. Further improvements throughout the process of patient screening, diagnosis, treatment, and follow-up need to be urgently addressed.

Resistant Hypertension in People With CKD: A Review.
Fay, KS, Cohen, DL
American journal of kidney diseases : the official journal of the National Kidney Foundation. 2021;(1):110-121
Abstract
Resistant hypertension is common in the chronic kidney disease population and conveys increased risk for adverse cardiovascular outcomes and the development of kidney failure. Recently, the American College of Cardiology and American Heart Association published a revised scientific statement on the definition and management of resistant hypertension, which codified the long-debated differences between pseudoresistant hypertension and true resistant hypertension. We review this distinction and its importance to nephrologists, who frequently encounter patients for whom antihypertensive therapy fails due to difficulty adhering to complex multidrug regimens. Second, we discuss the evaluation of patients with resistant hypertension, including appropriate screening and diagnostic testing for causes of secondary hypertension. Third, we examine the management of established resistant hypertension, including medication optimization, recent clinical trials supporting lifestyle modifications, and the evidence behind the routine use of mineralocorticoid receptor antagonists. Special attention is given to the vital role of diuretics in the treatment of patients with chronic kidney disease. We propose an algorithm for the diagnosis and management of these cases. Finally, we briefly discuss the current state of antihypertensive device therapies, including kidney denervation and baroreceptor-directed therapies.

Bioactive peptides from foods: production, function, and application.
Jia, L, Wang, L, Liu, C, Liang, Y, Lin, Q
Food & function. 2021;(16):7108-7125
Abstract
Bioactive peptides are a class of peptides with special physiological functions and have potential applications in human health and disease prevention. Bioactive peptides have gained much research attention because they affect the cardiovascular, endocrine, immune, and nervous systems. Recent research has reported that bioactive peptides are of great value for physiological function regulation, including antioxidation, anti-hypertension, antithrombosis, antibacterial properties, anti-cancer, anti-inflammation, anti-diabetic, anti-obesity, cholesterol-lowering, immunoregulation, mineral binding and opioid activities. The production of food-derived bioactive peptides is mainly through the hydrolysis of digestive enzymes and proteolytic enzymes or microbial fermentation. The purpose of this review is to introduce the production, function, application, challenges, and prospects of food-derived bioactive peptides.

Stroke Prevention in Older Adults: Recent Advances.
Spence, JD, Azarpazhooh, MR, Larsson, SC, Bogiatzi, C, Hankey, GJ
Stroke. 2020;(12):3770-3777
Abstract
The risks of stroke and dementia increase steeply with age, and both are preventable. At present, the best way to preserve cognitive function is to prevent stroke. Therapeutic nihilism based on age is common and unwarranted. We address recent advances in stroke prevention that could contribute greatly to prevention of stroke and dementia at a time when the aging of the population threatens to markedly increase the incidence of both. Issues discussed: (1) old patients benefit even more from lipid-lowering therapy than do younger patients; (2) patients with stiff arteries are at risk from a target systolic blood pressure <120 mm Hg; (3) the interaction of the intestinal microbiome, age, and renal function has important dietary implications for older adults; (4) anticoagulation with direct-acting oral anticoagulants should be prescribed more to old patients with atrial fibrillation; (5) B vitamins to lower homocysteine prevent stroke; and (6) most old patients in whom intervention is warranted for carotid stenosis would benefit more from endarterectomy than from stenting. An 80-year-old person has much to lose from a stroke and should not have effective therapy withheld on account of age. Lipid-lowering therapy, a more plant-based diet, appropriate anticoagulation or antiplatelet therapy, appropriate blood pressure control, B vitamins to lower homocysteine, and judicious intervention for carotid stenosis could do much to reduce the growing burden of stroke and dementia.

Chronic hypertension in pregnancy.
Battarbee, AN, Sinkey, RG, Harper, LM, Oparil, S, Tita, ATN
American journal of obstetrics and gynecology. 2020;(6):532-541
Abstract
Chronic hypertension and associated cardiovascular disease are among the leading causes of maternal and perinatal morbidity and death in the United States. Chronic hypertension in pregnancy is associated with a host of adverse outcomes that include preeclampsia, cesarean delivery, cerebrovascular accidents, fetal growth restriction, preterm birth, and maternal and perinatal death. There are several key issues related to the diagnosis and management of chronic hypertension in pregnancy where data are limited and further research is needed. These challenges and recent guidelines for the management of chronic hypertension are reviewed. Well-timed pregnancies are of utmost importance to reduce the risks of chronic hypertension; long-acting reversible contraceptive options are preferred. Research to determine optimal blood pressure thresholds for diagnosis and treatment to optimize short- and long-term maternal and perinatal outcomes should be prioritized along with interventions to reduce extant racial and ethnic disparities.

Abstract
Systemic arterial hypertension constitutes the leading cause of mortality worldwide, and affects people living at different altitudes above sea level (AASL). AASL has a major impact on cardiovascular function and various biologic pathways that regulate blood pressure-related phenotypes, but whether it affects the clinical response to antihypertensive therapy is unknown. The hemodynamic adaptations observed among lowlanders acutely exposed to high altitude (HA) is distinct from those observed among HA dwellers. However, the phenotypic patterns of hypertension and the response to standard antihypertensive agents among adults chronically exposed to different AASL are poorly understood. The authors describe the protocol for the INTERVENCION trial, a randomized clinical trial designed to assess the effects of three first-line antihypertensive monotherapies (a thiazide diuretic, an angiotensin receptor blocker, and a calcium channel blocker) on peripheral and central blood pressure, in-office blood pressure, and ambulatory blood pressure hemodynamics of hypertensive patients living at different AASL (low altitude, intermediate altitude, and high altitude). The primary end point is the reduction in 24-hour brachial systolic blood pressure. The INTERVENCION trial will provide the first clinical trial data regarding the influence of AASL on the response to antihypertensive monotherapy, as well as the hemodynamic characteristics of arterial hypertension at different AASL.

Impact of functional foods and nutraceuticals on high blood pressure with a special focus on meta-analysis: review from a public health perspective.
Venkatakrishnan, K, Chiu, HF, Wang, CK
Food & function. 2020;(4):2792-2804
Abstract
In recent times many researchers are expressing immense interest in nutraceuticals and functional foods for combating various diseases or abnormal conditions, especially against hypertension (HT). Persistent HT is medically referred to as chronic high blood pressure (BP) and considered to be one of the major risk factors for the deadliest diseases including cardiovascular disease (CVD) and cerebrovascular diseases. Hence HT poses a serious socio-economic burden worldwide, particularly to developing countries. The current treatment strategy for HT includes standard anti-hypertensive drugs, which are associated with many adverse effects and lower drug adherence rates. Therefore, an alternative or complementary natural therapy (functional foods or nutraceuticals or dietary supplements) would be the alternate choice along with a modified lifestyle pattern that might help to manage or combat HT and its related complications. During this review, the author would like to shed light on the basic science behind HT including pathophysiology and the impact of dietary salt on HT and the impact of various functional foods or nutraceuticals against HT in humans (meta-analysis and systemic review). This contribution gives a better idea (public health perspective) for choosing the best functional foods/nutraceuticals for the prevention, management or delaying the onset of HT and its associated conditions along with modified lifestyle patterns and standard anti-hypertensive drugs.

Evidence Gaps in the Identification and Treatment of Hypertension in Children.
Dionne, JM
The Canadian journal of cardiology. 2020;(9):1384-1393
Abstract
The ultimate goal of recognizing and treating hypertension in childhood is to prevent target-organ damage during childhood and to reduce the risk of adulthood cardiovascular disease. The quality of evidence to guide blood pressure management in children is lower than in adult medicine, yet some common findings support clinical practice recommendations. Oscillometric devices are increasingly replacing manual blood pressure measurements, but evidence shows that readings are not equivalent between the 2 methods. In addition, multiple blood pressure readings are needed before diagnosing a child with hypertension, but the optimal number and timing are still being determined. The recent American Academy of Pediatrics blood pressure guideline has revised the normative data tables and included threshold blood pressure limits which seem to identify children with higher cardiovascular risks. Threshold limits vary between guidelines, and the most accurate threshold has yet to be determined. Lifestyle modifications are a cornerstone of hypertension management, but the optimal diet and physical activity changes for beneficial effect are not known. When pharmacotherapy is needed, physicians have used drugs from all antihypertensive classes in children, yet only a few classes have been systematically studied. The long-term cardiovascular consequences of elevated blood pressure during childhood are under investigation and it seems that the lower the childhood blood pressure the better and that the rate of change during childhood is predictive of adulthood disease. With much still to learn, this article summarizes the evidence and the evidence gaps for the diagnosis, investigation, management, and outcomes of pediatric hypertension.

Special Article - The management of resistant hypertension: A 2020 update.
Carey, RM
Progress in cardiovascular diseases. 2020;(5):662-670
Abstract
Resistant hypertension (RH) induces higher morbidity and mortality due to cardiovascular disease and stroke than hypertension without treatment resistance. New guidelines define RH as blood pressure (BP) ≥130/80 mmHg in a patient taking ≥3 antihypertensive agents of different classes or BP <130/80 mmHg in a patient taking ≥4 antihypertensive drugs. According to the new definition, pseudo-resistance due to error in BP measurement, white coat effect and medication nonadherence must be excluded to make the diagnosis of RH. This 2020 update focuses on the lifestyle and antihypertensive drug management of RH and includes recent proof-of-principle trials of renal nerve ablation in hypertension. Stepwise evidence-based pharmacologic treatment of RH includes optimization of the 3-drug regimen, substitution of a thiazide-like for a thiazide diuretic and addition of a mineralocorticoid receptor antagonist as the fourth drug. Non-evidence-based recommendations include addition of a β-blocker as the fifth drug and switching to a minoxidil-based regimen as the final step in achieving BP control.

Investigation and Treatment of High Blood Pressure in Young People: Too Much Medicine or Appropriate Risk Reduction?
Hinton, TC, Adams, ZH, Baker, RP, Hope, KA, Paton, JFR, Hart, EC, Nightingale, AK
Hypertension (Dallas, Tex. : 1979). 2020;(1):16-22
Abstract
Hypertension among young people is common, affecting 1 in 8 adults aged between 20 and 40 years. This number is likely to increase with lifestyle behaviors and lowering of hypertension diagnostic thresholds. Early-life factors influence blood pressure (BP) although the mechanisms are unclear; BP tracks strongly within individuals from adolescence through to later life. Higher BP at a young age is associated with abnormalities on heart and brain imaging and increases the likelihood of cardiovascular events by middle age. However, diagnosis rates are lower, and treatment is often delayed in young people. This reflects the lack of high-quality evidence that lowering BP in young adults improves cardiovascular outcomes later in life. In this review, we evaluate the current evidence regarding the association between BP in young adult life and adverse cardiovascular outcomes later in life. Following this, we discuss which young people with raised BP should be investigated for secondary causes of hypertension. Third, we assess the current models to assess cardiovascular risk and show a lack of validation in the younger age group. Fourth, we evaluate the evidence for lifestyle interventions in this age group and demonstrate a lack of persistence in BP lowering once the initial intervention has been delivered. Fifth, we address the pros and cons of drug treatment for raised BP in young people. Finally, there are unique life events in young people, such as pregnancy, that require specific advice on management and treatment of BP.
