Shokoples BG, Paradis P, Schiffrin EL. Immunological insights into hypertension: unraveling triggers and potential therapeutic avenues. Hypertens Res 2024; 47:2115-2125. [PMID: 38778172 DOI: 10.1038/s41440-024-01731-6] [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: 01/27/2024] [Revised: 04/02/2024] [Accepted: 04/23/2024] [Indexed: 05/25/2024]
Abstract
Hypertension remains the leading cause of morbidity and mortality worldwide. Despite its prevalence, the development of novel antihypertensive therapies has only recently accelerated, with novel agents not yet commercialized, leaving a substantial proportion of individuals resistant to existing treatments. The intricate pathophysiology of hypertension is now understood to involve chronic low-grade inflammation, which places the immune system in the spotlight as a potential target for new therapeutics. This review explores the factors that initiate and sustain an immune response in hypertension, offering insights into potential targets for new treatments. Several factors contribute to immune activation in hypertension, including diet and damage-associated molecular pattern (DAMP) generation. Diets rich in fat or sodium can promote inflammation by inducing intestinal barrier dysfunction and triggering salt-sensitive receptors in T cells and dendritic cells. DAMPs, such as extracellular adenosine triphosphate and heat-shock protein 70, are released during episodes of increased blood pressure, contributing to immune cell activation and inflammation. Unconventional innate-like γδ T cells contribute to initiating and maintaining an immune response through their potential involvement in antigen presentation and regulating cytokine-mediated responses. Immunologic memory, sustained through the formation of effector memory T cells after exposure to hypertensive insults, likely contributes to maintaining an immune response in hypertension. When exposed to hypertensive insults, these memory cells are rapidly activated and contribute to elevated blood pressure and end-organ damage. Evidence from human hypertension, although limited, supports the relevance of distinct immune pathways in hypertension, and highlights the potential of targeted immune interventions in human hypertension. Diet and acute bouts of high blood pressure result in the release of dietary triggers, neoantigens, and damage-associated molecular patterns (DAMPs), which promote immune system activation. Elements such as lipopolysaccharides (LPS), sodium, heat-shock protein (HSP)70, extracellular adenosine triphosphate (eATP), and growth arrest-specific 6 (GAS6) promote activation of innate immune cells such as dendritic cells (DCs) and monocytes (Mo) through their respective receptors (toll-like receptor [TLR]4, amiloride-sensitive epithelial sodium channel [ENaC], TLR2/4, P2X7 receptor [P2RX7], and Axl) leading to costimulatory molecule expression and interleukin (IL)-1β and IL-23 production. The neoantigens HSP70 and isolevuglandins (IsoLGs) are presented to T cells by DCs and possibly γδ T cells, triggering T cell activation, IL-17 and interferon (IFN)-γ production, and the formation of T effector memory (TEM) cells in the kidney, perivascular adipose tissue, bone marrow, and spleen. Exposure of TEM cells to their cognate antigen or previous activating stimuli causes these cells rapid expansion and activation. Cumulatively, this inflammatory state contributes to hypertension and end-organ damage.

Abstract
Hypertension is a primary contributor to cardiovascular disease, and the leading risk factor for loss of quality adjusted life years. Up to 50% of the cases of hypertension in the United States remain uncontrolled. Additionally, 8%-18% of the hypertensive population have resistant hypertension; uncontrolled pressure despite 3 different antihypertensive agents. Recently, catheter-based percutaneous renal denervation emerged as a method for ablating renal sympathetic nerves for difficult-to-control hypertension. Initial randomized (non-sham) trials and registry analyses showed impressive benefit, but the first sham-controlled randomized controlled trial using monopolar radiofrequency ablation showed limited benefit. With refinement of techniques to include multipolar radiofrequency, ultrasound denervation, and direct ethanol injection, randomized controlled trials demonstrated significant blood pressure improvement, leading to US Food and Drug Administration approval of radiofrequency- and ultrasound-based denervation technologies. In this review article, we summarize the major randomized sham-controlled trials and societal guidelines regarding the efficacy and safety of renal artery denervation for the treatment of uncontrolled hypertension.

Differences in Antihypertensive Medication Prescription Profiles Between 2009 and 2021: A Retrospective Cohort Study of CARTaGENE. Can J Kidney Health Dis 2024; 11:20543581241234729. [PMID: 38601903 PMCID: PMC11005488 DOI: 10.1177/20543581241234729] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2023] [Accepted: 01/14/2024] [Indexed: 04/12/2024] Open
Abstract
Background Although blood pressure (BP) control is critical to prevent cardiovascular diseases, hypertension control rates in Canada are in decline. Objective To assess this issue, we sought to evaluate the differences in antihypertensive medication prescription profiles in the province of Quebec between 2009 and 2021. Design This is a retrospective cohort study. Setting We used data from the CARTaGENE population-based cohort linked to administrative health databases. Patients Participants with any drug claim in the 6 months prior to the end of follow-up were included. Measurements Guideline-recommended antihypertensive drug prescription profiles were assessed at the time of enrollment (2009-2010) and end of follow-up (March 2021). Methods Prescriptions practices from the 2 time periods were compared using Pearson's chi-square tests. A sensitivity analysis was performed by excluding participants in which antihypertensive drugs may not have been prescribed solely to treat hypertension (presence of atrial fibrillation/flutter, ischemic heart disease, heart failure, chronic kidney disease, or migraines documented prior to or during follow-up). Results Of 8447 participants included in the study, 31.4% and 51.3% filled prescriptions for antihypertensive drugs at the beginning and end of follow-up. In both study periods, guideline-recommended monotherapy was applied in most participants with hypertension (77.9% vs 79.5%, P = .3), whereas optimal 2 and 3-drug combinations were used less frequently (62.0% vs 61.4%, P = .77, 51.9% vs 46.7%, P = .066, respectively). Only the use of long-acting thiazide-like diuretics (9.5% vs 27.7%, P < .001) and spironolactone as a fourth-line agent (8.3% vs 15.9%, P = .054) increased with time but nonetheless remained infrequent. Results were similar in the sensitivity analysis. Limitations Specific indication of the prescribed antihypertensive medications and follow-up BP data was not available. Conclusions Application of hypertension guidelines for the choice of antihypertensive drugs remains suboptimal, highlighting the need for education initiatives. This may be an important step to raise BP control rates in Canada.

Cardiol Res Pract 2023; 2023:5586403. [PMID: 38115947 PMCID: PMC10730254 DOI: 10.1155/2023/5586403] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/20/2023] [Revised: 10/23/2023] [Accepted: 11/24/2023] [Indexed: 12/21/2023] Open
Abstract
Background Hypertension is a major global health concern, and lifestyle modifications have been recommended as first-line treatment for hypertension in many guidelines. However, different guidelines may recommend different types of lifestyle adjustment, and it is unclear which ones are most effective. In this review, we compared hypertension guidelines to identify any differences and/or consensus in content, efficacy, and timing of initiation of lifestyle modifications. Methods We conducted a search of databases to identify hypertension guidelines available in English. We extracted and compared information about lifestyle modifications recommended by the guidelines. Results Five hypertension guidelines from America, Europe, the UK, Canada, and the International Society of Hypertension are included. They all recommend diet adaptation, sodium reduction, alcohol restriction, physical exercise, and weight reduction. Other lifestyle interventions emphasized by some guidelines, such as potassium supplementation, smoking cessation, and stress management, are not recommended by all the five guidelines. Among lifestyle changes, the dietary approaches to stop hypertension (DASH) diet may be considered the most effective treatment for reducing blood pressure. These guidelines recommend that for patients with high-normal blood pressure or grade 1 hypertension without high risk factors, lifestyle medicine should be used first for 3-6 months, if blood pressure is still not controlled, then start medication. For those patients who need drug treatment, lifestyle changes can also enhance the effects of antihypertensive therapy. Conclusion Lifestyle modifications are crucial in the treatment of hypertension and should be recommended to most hypertensive patients. Among these lifestyle interventions, diet adaptation containing low sodium and alcohol restriction may be the most effective in reducing blood pressure. Physical exercise and weight reduction are also recommended. In some cases, lifestyle modifications should be tried first. They may also enhance the effects of antihypertensive drugs in other patients.

Abstract
Background The hypertension specialist often receives referrals of patients with young-onset, severe, difficult-to-control hypertension, patients with hypertensive emergencies, and patients with secondary causes of hypertension. Specialist hypertension care compliments primary care for these complex patients and contributes to an overall hypertension control strategy. The objective of this study was to characterize hypertension centres and the practice patterns of Canadian hypertension specialists. Methods Adult hypertension specialists across Canada were surveyed to describe hypertension centres and specialist practice in Canada, including the following: the patient population managed by hypertension specialists; details on how care is provided; practice pattern variations; and differences in access to specialized hypertension resources across the country. Results The survey response rate was 73.5% from 25 hypertension centres. Most respondents were nephrologists and general internal medicine specialists. Hypertension centres saw between 50 and 2500 patients yearly. A mean of 17% (± 15%) of patients were referred from the emergency department and a mean of 52% (± 24%) were referred from primary care. Most centres had access to specialized testing (adrenal vein sampling, level 1 sleep studies, autonomic testing) and advanced therapies for resistant hypertension (renal denervation). Considerable heterogeneity was present in the target blood pressure in young people with low cardiovascular risk and in the diagnostic algorithms for investigating secondary causes of hypertension. Conclusions These results summarize the current state of hypertension specialist care and highlight opportunities for further collaboration among hypertension specialists, including standardization of the approach to specialist care for patients with hypertension.

[PMID: 37451613 DOI: 10.1016/j.cjca.2023.07.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2023] [Revised: 06/26/2023] [Accepted: 07/07/2023] [Indexed: 07/18/2023] Open
Abstract
BACKGROUND Hypertension, clinically defined by elevated blood pressure (BP), is an important cause of mortality and morbidity worldwide. Many risk factors for hypertension are known, including a positive family history, which suggests that genetics contribute to interindividual BP variation. Genome-wide association studies (GWAS) have identified > 1000 loci associated with BP, yet the identity of the genes responsible for these associations remains largely unknown. METHODS To pinpoint genes that causally affect variation of BP in humans, we analyzed predicted loss-of-function (pLoF) variants in the UK Biobank whole-exome sequencing dataset (n = 454,709 participants, 6% non-European ancestry). We analyzed genetic associations between systolic or diastolic BP (SBP/DBP) and single pLoF variants (additive and recessive genetic models) as well as with the burden of very rare pLoF variants (minor allele frequency [MAF] < 0.01%). RESULTS Single pLoF variants in 10 genes were associated with BP (ANKDD1B, ENPEP, PNCK, BTN3A2, C1orf145 [OBSCN-AS1], CASP9, DBH, KIAA1161 [MYORG], OR4X1, and TMC3). We also found a burden of rare pLoF variants in 5 additional genes associated with BP (TTN, NOS3, FES, SMAD6, COL21A1). Except for PNCK, which is located on the X-chromosome, these genes map near variants previously associated with BP by GWAS, validating the study of pLoF variants to prioritize causal genes at GWAS loci. CONCLUSIONS Our study highlights 15 genes that likely modulate BP in humans, including 5 genes that harbour pLoF variants associated with lower BP.

Abstract
PURPOSE OF REVIEW This narrative review aims to assess the pathophysiology, diagnosis, and treatment of resistant hypertension (RH) in end-stage kidney disease (ESKD) patients on dialysis, with a specific focus on the effect of renal denervation (RDN) on short-term and long-term blood pressure (BP) control. Additionally, we share our experience with the use of RDN in an amyloidotic patient undergoing hemodialysis with RH. RECENT FINDINGS High BP, an important modifiable cardiovascular risk factor, is often observed in patients in ESKD, despite the administration of multiple antihypertensive medications. However, in clinical practice, it remains challenging to identify RH patients on dialysis treatment because of the absence of specific definition for RH in this context. Moreover, the use of invasive approaches, such as RDN, to treat RH is limited by the exclusion of patients with reduced renal function (eGFR < 45 mL/min/1.73 m3) in the clinical trials. Nevertheless, recent studies have reported encouraging results regarding the effectiveness of RDN in stage 3 and 4 chronic kidney disease (CKD) and ESKD patients on dialysis, with reductions in BP of nearly up to 10 mmhg. Although multiple underlying pathophysiological mechanisms contribute to RH, the overactivation of the sympathetic nervous system in ESKD patients on dialysis plays a crucial role. The diagnosis of RH requires both confirmation of adherence to antihypertensive therapy and the presence of uncontrolled BP values by ambulatory BP monitoring or home BP monitoring. Treatment involves a combination of nonpharmacological approaches (such as dry weight reduction, sodium restriction, dialysate sodium concentration reduction, and exercise) and pharmacological treatments. A promising approach for managing of RH is based on catheter-based RDN, through radiofrequency, ultrasound, or alcohol infusion, directly targeting on sympathetic overactivity.

Abstract
Resistant hypertension (RHT) is typically defined as blood pressure that remains above guideline-directed targets despite the use of three anti-hypertensives, usually including a diuretic, at optimal or maximally tolerated doses. It is generally estimated to affect 10-30% of those diagnosed with hypertension, though the true incidence might be lower after one factor in the prevalence of non-adherence. Risk factors for its development include diabetes, obesity and other adverse lifestyle factors, and a diagnosis of RHT confers a greater risk of adverse cardiovascular outcomes, such as stroke, heart failure and mortality. It is essential to exclude pseudoresistance and secondary hypertension and to ensure non-pharmacologic management is optimised prior to consideration of fourth-line anti-hypertensive agents or advanced interventions, such as device therapies. In this review, we will cover the different definitions of RHT, along with the importance of careful diagnosis and management strategies, and discuss newer agents and research needs.

[PMID: 37109761 PMCID: PMC10145005 DOI: 10.3390/medicina59040803] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/12/2023] [Revised: 04/12/2023] [Accepted: 04/18/2023] [Indexed: 04/29/2023]
Abstract
With the medical and social importance of resistant arterial hypertension (HTN) in mind, we had three goals in this paper: to study the definitions of resistant HTN in the guidelines on the topic, to analyze them, and to suggest some improvements. We found (at least) eleven insufficiencies in the definition of resistant HTN: (1) different blood pressure (BP) values are used for diagnoses; (2) the number of BP measurements is not specified; (3) the time-frame for the definition is not obtained; (4) it fails to provide normal or target or controlled BP values; (5) secondary HTN is not currently defined as true resistant HTN, but as apparently treatment-resistant HTN; (6) the definition usually directly incorporates BP cut-offs for systolic BP (sBP) and diastolic BP (dBP) making the diagnosis temporary; (7) stress is not included in the exclusion strategy for resistant HTN; (8) there is potentially a need to introduce a category of recovered resistant HTN; (9) to what degree do healthy lifestyle measures have to be fulfilled to consider it as sufficient to change the diagnosis from "apparent treatment-resistant HTN" to the "resistant HTN"; (10) sBP values normal-for-the-age for 61 and 81 year old patients in some guidelines fulfill the criterion for resistant HTN; (11) it probably ought to read "In the absence of contraindications and compelling indications…" in the others. We believe that it is better to use the phrase "above the target BP" for the definition of (treatment) resistant HTN, because the whole story of resistant HTN is related to non-responders to antihypertensive treatment. Therefore, as we treat to target and not to normal values, it is appropriate to define resistant HTN as an insufficiency to reach the target BP values. Moreover, the definition of (treatment) resistant HTN should not be universal for every patient with HTN, but it should be age-related: (treatment) resistant HTN is elevated BP over the target/normal BP values. Using this modification, there will be no need to automatically change the definition of resistant HTN when we change the BP targets in the future.

Benefit of treatment based on indapamide mostly combined with perindopril on mortality and cardiovascular outcomes: a pooled analysis of four trials. J Hypertens 2023; 41:508-515. [PMID: 36633311 PMCID: PMC9894155 DOI: 10.1097/hjh.0000000000003368] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2022] [Revised: 11/21/2022] [Accepted: 12/07/2022] [Indexed: 01/13/2023]
Abstract
OBJECTIVE The aim of this study was to assess the reduction in all-cause death and cardiovascular outcomes associated with the administration of the thiazide-like diuretic indapamide monotherapy or in combination with perindopril as a blood pressure lowering drug in randomized controlled trials (RCTs). METHOD Aggregate data from four published RCTs conducted versus matching placebo were pooled: PATS, a 2-year study (indapamide), and PROGRESS, a 4-year study (indapamide and perindopril), both in patients with a history of stroke or transient ischemic attack; ADVANCE, a 4-year study in patients with type 2 diabetes and cardiovascular risk factor (single-pill combination perindopril/indapamide) and HYVET, a 2-year study in very elderly hypertensive individuals (indapamide and an option of perindopril). The pooled effect (fixed and random) estimate (hazard ratio) was reported with corresponding 95% confidence intervals and P values. Treatment discontinuations were also analysed to assess the net benefit of the treatment. RESULTS The population involved 24 194 patients (active: 12 113, placebo: 12 081). The fixed-effects meta-analysis of the three mortality endpoints found low statistical heterogeneity ( I2 = 0). Statistically significant risk reductions in the indapamide with or without perindopril-treated patients as compared to placebo were observed for all-cause death (-15%), cardiovascular death (-21%), fatal stroke (-36%) and all strokes (-27%). Other cardiovascular outcomes were improved (risk reduction, 22 to 36%). As expected, discontinuation rates for safety (two studies) were higher in the active group (6.4 vs. 3.9%), while they were similar when discontinuation for any reason is concerned (18.4 vs. 18.0%). CONCLUSION Across medium to high cardiovascular risk population, long-term indapamide, mostly combined with perindopril-based treatment, provided evidence of benefit on mortality and morbidity.

Effects of exergame and bicycle exercise intervention on blood pressure and executive function in older adults with hypertension: A three-group randomized controlled study. Exp Gerontol 2023; 173:112099. [PMID: 36681131 DOI: 10.1016/j.exger.2023.112099] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2022] [Revised: 01/16/2023] [Accepted: 01/18/2023] [Indexed: 01/21/2023]
Abstract
Management of hypertension and prevention of cognitive decline are challenging public health problems. However, the effects of exergame intervention on blood pressure (BP) remain to be explored, and whether exergame intervention is an effective alternative to traditional physical exercise intervention for older adults with hypertension remains to be demonstrated. This study aimed to explore the effectiveness of moderate-intensity exergame intervention and bicycle exercise training on BP and executive function in older hypertensive patients. A total of 128 participants were randomly assigned to the exergame intervention group (n = 41), bicycle exercise intervention group (n = 44), and control group (n = 43). The intervention groups exercised for 60 min, 3 times per week, for 16 weeks, while the control group maintained their normal lifestyle. The results revealed that there were no significant differences between two intervention groups and control group in systolic BP and diastolic BP changes (ps > 0.05). Both intervention groups demonstrated significant improvements in working memory when compared with control group (exergame intervention group: -461.9 ms, p = 0.025; bicycle exercise intervention group: -470.1 ms, p = 0.021). There were no significant differences in systolic BP, diastolic BP, or working memory between the two intervention groups after 16 weeks of training (ps > 0.05). No difference in inhibition or cognitive flexibility was observed between the intervention and control groups (ps > 0.05). The current results showed that moderate-intensity exergame intervention did not produce significant benefits in reducing BP, but yielded similar beneficial effects in working memory to that of bicycle exercise intervention. More studies are needed on whether exergame intervention has the potential to be a promising supplemental therapeutic tool for older adults with hypertension.

Abstract
Some national guidelines since 2017 considered the most common method for diagnosing and controlling hypertension (HTN) (office blood pressure (OBP) measurement) as screening only. Automated OBP (AOBP) measurement claims to be a unique method by obtaining a standardized result, even in primary health care. AOBP improves the reliability of data by reducing the influence of various errors on result. However, although the level of AOBP is on average lower than similar OBP in clinical and research practice and is comparable to the mean 24-hour BP monitoring, at present, all international guidelines emphasize the mandatory use of ambulatory BP measurements for diagnostic purposes. Whether the results of AOBP and the reference level ≥130/80 mm Hg are equivalent with the same OBP level, the use of which is associated with an increase in the prevalence of hypertension and insufficient control of antihypertensive therapy, is a question for research. Compared with conventional OBP, the use of AOBP in conjunction with outpatient measurement leads to a reduction in the proportion and timing of initiation of treatment in patients with masked HTN, whose cardiovascular risk is similar to that of patients with stable HTN. However, the widespread implementation of AOBP is hindered by the high cost and lack of accumulated data. The review analyzes in detail the limitations and advantages of various types of BP measurement, as well as the potential of using AOBP in modern clinical and research practice.

Abstract
Background Arterial hypertension is facing some changes in the last years. Its prevalence is increasing in elderly subjects. This growing prevalence is due to longer survival of the population worldwide, among other factors. On the other hand, recent guidelines have insisted in the relevance of out of office blood pressure measurements, to improve diagnostic and management of hypertension. Therefore, elderly subjects with hypertension could benefit from out of office blood pressure measurements, like ambulatory blood pressure measurements; nevertheless, there are very few or no specific recommendations regarding this. Aim In this review, we will gather the most important information about this subject. Results As hypertension in the elderly has some specific characteristics related to aging of the cardiovascular system, the most important aspect could be that these characteristics make ambulatory blood pressure measurement suitable for its use in elderly. Among those a higher prevalence of white coat hypertension, white coat phenomenon, and a higher nocturnal blood pressure and higher prevalence of nondipper and riser pattern, represent aspects that should be considered for better diagnostic and an improved management. Conclusion As the prevalence of hypertension will grow in the next years, more studies specifically directed to this subject are needed.

Abstract
Background Hypertension has been shown to be an important risk factor in IgA nephropathy (IgAN). The 2021 the Kidney Disease Improving Global Outcomes (KDIGO) Guideline proposes a target systolic blood pressure (SBP) of less than 120 mmHg in patients with Chronic Kidney Disease (CKD) not receiving dialysis. However, whether lowering SBP from <140– <120 mm Hg is renoprotective is unknown. This study aims to evaluate the association of SBP and the progression of IgAN, then explore whether lowering SBP from <140– <120 mm Hg is renoprotective. Methods Overall, 2,240 patients with IgAN were enrolled in this study. Cox proportional hazards models and restricted cubic splines were used to estimate the associations between SBP and kidney failure events which are defined as 50% estimated glomerular filtration rate (eGFR) decline or kidney failure. Results After a median follow-up of 30.05 months, 217 (9.69%) patients reached composite kidney failure events. The association of SBP and kidney failure events showed a linear relationship. The risk of kidney failure events was greater with higher SBP. Compared with SBP <120 mm Hg, the hazard ratio was 1.85 (1.16–2.97, p = 0.010) for SBP <140 mm Hg after adjustment for traditional risk factors. The renoprotective benefits of therapy targeting SBP <120 mm Hg from SBP <140 mm Hg was detectable within the subgroup with proteinuria >1.0 g/d, CKD 1-3a stage, but not those with proteinuria ≤ 1.0 g/d and CKD 3b-4 stage. Conclusions In patients with IgAN, SBP was independently associated with composite kidney failure events. Lowering SBP from <140– <120 mm Hg was renoprotective.

Abstract
Resistant hypertension is common and known to be a risk factor for cardiovascular events, including stroke, myocardial infarction, heart failure, and cardiovascular mortality, as well as adverse renal events, including chronic kidney disease and end-stage kidney disease. This review will discuss the definition of resistant hypertension as well as the most recent evidence regarding its diagnosis, evaluation, and management. The issue of medication non-adherence and its association with apparent treatment-resistant hypertension will be addressed. Non-pharmacological interventions for the treatment of resistant hypertension will be reviewed. Particular emphasis will be placed on pharmacological interventions, highlighting the role of mineralocorticoid receptor antagonists and sodium-glucose cotransporter-2 inhibitors and device therapy, including renal denervation, baroreceptor activation or modulation, and central arteriovenous fistula creation.

Abstract
BACKGROUND Although lifestyle modifications generally are effective in lowering blood pressure (BP) among patients with unmedicated hypertension and in those treated with 1 or 2 antihypertensive agents, the value of exercise and diet for lowering BP in patients with resistant hypertension is unknown. METHODS One hundred forty patients with resistant hypertension (mean age, 63 years; 48% female; 59% Black; 31% with diabetes; 21% with chronic kidney disease) were randomly assigned to a 4-month program of lifestyle modification (C-LIFE [Center-Based Lifestyle Intervention]) including dietary counseling, behavioral weight management, and exercise, or a single counseling session providing SEPA (Standardized Education and Physician Advice). The primary end point was clinic systolic BP; secondary end points included 24-hour ambulatory BP and select cardiovascular disease biomarkers including baroreflex sensitivity to quantify the influence of the baroreflex on heart rate, high-frequency heart rate variability to assess vagally mediated modulation of heart rate, flow-mediated dilation to evaluate endothelial function, pulse wave velocity to assess arterial stiffness, and left ventricular mass to characterize left ventricular structure. RESULTS Between-group comparisons revealed that the reduction in clinic systolic BP was greater in C-LIFE (-12.5 [95% CI, -14.9 to -10.2] mm Hg) compared with SEPA(-7.1 [-95% CI, 10.4 to -3.7] mm Hg) (P=0.005); 24-hour ambulatory systolic BP also was reduced in C-LIFE (-7.0 [95% CI, -8.5 to -4.0] mm Hg), with no change in SEPA (-0.3 [95% CI, -4.0 to 3.4] mm Hg) (P=0.001). Compared with SEPA, C-LIFE resulted in greater improvements in resting baroreflex sensitivity (2.3 ms/mm Hg [95% CI, 1.3 to 3.3] versus -1.1 ms/mm Hg [95% CI, -2.5 to 0.3]; P<0.001), high-frequency heart rate variability (0.4 ln ms2 [95% CI, 0.2 to 0.6] versus -0.2 ln ms2 [95% CI, -0.5 to 0.1]; P<0.001), and flow-mediated dilation (0.3% [95% CI, -0.3 to 1.0] versus -1.4% [95% CI, -2.5 to -0.3]; P=0.022). There were no between-group differences in pulse wave velocity (P=0.958) or left ventricular mass (P=0.596). CONCLUSIONS Diet and exercise can lower BP in patients with resistant hypertension. A 4-month structured program of diet and exercise as adjunctive therapy delivered in a cardiac rehabilitation setting results in significant reductions in clinic and ambulatory BP and improvement in selected cardiovascular disease biomarkers.

Abstract
OBJECTIVE Renal sympathetic denervation (RDN) is an alternative treatment for resistant hypertension (RH). This study aims to compare ablation effects using three radiofrequency applicators (i.e., balloon-based four electrodes, spiral and monopolar devices). METHODS An idealized three-dimensional model of the renal artery was established using COMSOL Multiphysics to mimic radiofrequency ablation (RFA). Radiofrequency (RF) energy was delivered to the tissue at the same simulation settings, i.e., 4, 6, and 8 W for 60 s, using the three abovementioned RF applicators. The temperature distribution in the tissue was calculated using the coupled electrical-thermal-fluid finite element method. Lesion borders were defined using 50 °C isotherms. The maximum lesion depth, width, area, and circumferential coverage rate were compared among the three applicators at a blood flow of 0.4 m/s. Monopolar RF ablations in a renal artery phantom model were performed to validate the reliability of the simulation method. RESULTS The balloon-based system yields greater lesion depths and widths compared with spiral and monopolar denervation under the same power. The range of maximum lesion depth is 1.58-3.11 mm for balloon-based RDN, 0.90-1.81 mm for spiral RDN and 1.12-2.38 mm for monopolar RDN, at a power of 4-8 W. The corresponding ranges of maximum lesion width are 2.22-5.73, 1.48-3.54, and 1.93-5.31 mm, respectively, and the circumferential coverage rates of the renal artery are 41.43%-91.99%, 31.71%-66.23%, and 9.55%-23.06%, respectively. The average velocity after balloon-based, spiral, and monopolar RDN increases by 3, 5, and 1 cm/s, respectively. The validation of the computer model offered prediction errors are <5% in terms of temperature at different locations (i.e., 2, 4, and 8 mm). CONCLUSIONS In terms of lesion size, balloon-based RDN appears to be the best option for the treatment of RH. However, the change in flow velocity in the arterial flow field suggests that its hemodynamic changes must be prioritized for investigating its safety. Although spiral catheter ablation yields the smallest lesion size and a significant change in flow velocity in the flow field, its coverage rate is larger than that of monopolar RDN; compared with balloon-based RDN, it did not obstruct most of the blood flow.

Abstract
Aims Patients with heart failure and preserved ejection fraction (HFpEF) frequently have difficult-to-control hypertension. We examined the effect of neprilysin inhibition on ‘apparent resistant hypertension’ in patients with HFpEF in the PARAGON-HF trial, which compared the effect of sacubitril–valsartan with valsartan. Methods and results In this post hoc analysis, patients were categorized according to systolic blood pressure at the end of the valsartan run-in (n = 4795). ‘Apparent resistant hypertension’ was defined as systolic blood pressure ≥140 mmHg (≥135 mmHg if diabetes) despite treatment with valsartan, a calcium channel blocker, and a diuretic. ‘Apparent mineralocorticoid receptor antagonist (MRA)-resistant’ hypertension was defined as systolic blood pressure ≥140 mmHg (≥135 mmHg if diabetes) despite the above treatments and an MRA. The primary outcome in the PARAGON-HF trial was a composite of total hospitalizations for heart failure and death from cardiovascular causes. We examined clinical endpoints and the safety of sacubitril–valsartan according to the hypertension category. We also examined reductions in blood pressure from the end of valsartan run-in to Weeks 4 and 16 after randomization. Overall, 731 patients (15.2%) had apparent resistant hypertension and 135 (2.8%) had apparent MRA-resistant hypertension. The rate of the primary outcome was higher in patients with apparent resistant hypertension [17.3; 95% confidence interval (CI) 15.6–19.1 per 100 person-years] compared to those with a controlled systolic blood pressure (13.4; 12.7–14.3 per 100 person-years), with an adjusted rate ratio of 1.28 (95% CI 1.05–1.57). The reduction in systolic blood pressure at Weeks 4 and 16, respectively, was greater with sacubitril–valsartan vs. valsartan in patients with apparent resistant hypertension [−4.8 (−7.0 to −2.5) and 3.9 (−6.6 to −1.3) mmHg] and apparent MRA-resistant hypertension [−8.8 (−14.0 to −3.5) and −6.3 (−12.5 to −0.1) mmHg]. The proportion of patients with apparent resistant hypertension achieving a controlled systolic blood pressure by Week 16 was 47.9% in the sacubitril–valsartan group and 34.3% in the valsartan group [adjusted odds ratio (OR) 1.78, 95% CI 1.30–2.43]. In patients with apparent MRA-resistant hypertension, the respective proportions were 43.6% vs. 28.4% (adjusted OR 2.63, 95% CI 1.18–5.89). Conclusion Sacubitril–valsartan may be useful in treating apparent resistant hypertension in patients with HFpEF, even in those who continue to have an elevated blood pressure despite treatment with at least four antihypertensive drug classes, including an MRA.

Executive summary of the KDIGO 2021 Clinical Practice Guideline for the Management of Blood Pressure in Chronic Kidney Disease. Kidney Int 2021; 99:559-569. [PMID: 33637203 DOI: 10.1016/j.kint.2020.10.026] [Citation(s) in RCA: 136] [Impact Index Per Article: 45.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2020] [Revised: 10/25/2020] [Accepted: 10/27/2020] [Indexed: 02/06/2023]
Abstract
The Kidney Disease: Improving Global Outcomes (KDIGO) 2021 Clinical Practice Guideline for the Management of Blood Pressure in Chronic Kidney Disease for patients not receiving dialysis represents an update to the KDIGO 2012 guideline on this topic. Development of this guideline update followed a rigorous process of evidence review and appraisal. Guideline recommendations are based on systematic reviews of relevant studies and appraisal of the quality of the evidence. The strength of recommendations is based on the "Grading of Recommendations Assessment, Development and Evaluation" (GRADE) approach. The scope includes topics covered in the original guideline, such as optimal blood pressure targets, lifestyle interventions, antihypertensive medications, and specific management in kidney transplant recipients and children. Some aspects of general and cardiovascular health, such as lipid and smoking management, are excluded. This guideline also introduces a chapter dedicated to proper blood pressure measurement since all large randomized trials targeting blood pressure with pivotal outcomes used standardized preparation and measurement protocols adhered to by patients and clinicians. Based on previous and new evidence, in particular the Systolic Blood Pressure Intervention Trial (SPRINT) results, we propose a systolic blood pressure target of less than 120 mm Hg using standardized office reading for most people with chronic kidney disease (CKD) not receiving dialysis, the exception being children and kidney transplant recipients. The goal of this guideline is to provide clinicians and patients a useful resource with actionable recommendations supplemented with practice points. The burden of the recommendations on patients and resources, public policy implications, and limitations of the evidence are taken into consideration. Lastly, knowledge gaps and recommendations for future research are provided.

Abstract
Hypertension Canada's 2020 guidelines for the prevention, diagnosis, risk assessment, and treatment of hypertension in adults and children provide comprehensive, evidence-based guidance for health care professionals and patients. Hypertension Canada develops the guidelines using rigourous methodology, carefully mitigating the risk of bias in our process. All draft recommendations undergo critical review by expert methodologists without conflict to ensure quality. Our guideline panel is diverse, including multiple health professional groups (nurses, pharmacy, academics, and physicians), and worked in concert with experts in primary care and implementation to ensure optimal usability. The 2020 guidelines include new guidance on the management of resistant hypertension and the management of hypertension in women planning pregnancy.
