Molecular Imaging of Renin Activity using Fluorogenic Nanoprobes for Precision Antihypertensive Therapy.

Life-threatening hypertension remains inadequately controlled in clinics due to its heterogenous renin levels. Rapid stratification of hypertension through renin analysis is crucial for effective personalized treatment, yet an ultrasensitive detection approach is currently lacking. Here, we report activatable renin nanoprobes (ARNs) for non-invasive and ultrasensitive profiling of renin activity and guiding antihypertensive treatment decision through near-infrared fluorescence (NIRF) in vivo imaging and in vitro urinalysis. ARNs are intrinsically non-fluorescent due to NIRF reporter connected to a gold nanocluster through a renin-responsive peptide. In hyperreninemia mouse models, ARNs specifically react with renin to liberate the renal clearable NIRF reporter for accurate renin detection that outperforms the gold standard radioimmunoassay. Such specific and sensitive detection also enables imaging-based high-throughput screening of antihypertensive drugs. In hypertensive rat models, ARNs enable ultrasensitive detection of both plasma and urinary renin, facilitating renin-guided precision treatment and significantly improving hypertension control rate (90% versus 58%). Our nanoprobe platform holds great potential for assisting clinicians in rapidly and accurately classifying hypertensive patients and improving outcomes through tailored treatment selection.

Primary aldosteronism with postoperative elevation of aldosterone treated effectively by finerenone: A case report.

The authors report a case of primary aldosteronism (PA) with postoperative elevation of aldosterone treated effectively by finerenone. The patient was a hypertensive man with a 30-year history of hypertension and sustained an acute myocardial infarction 5 years ago. Bilateral adrenal nodules with hyperplasia were detected and PA was confirmed. His blood potassium, direct renin concentration, and aldosterone level returned to normal after surgery of right adrenalectomy. However, 1 year after surgery, he experienced a decrease in blood potassium and an increase in aldosterone. A saline infusion test revealed an aldosterone level of 124.47 pg/mL. The patient consented to treatment with finerenone. His aldosterone and potassium levels and blood pressure have been controlled well during follow-up. This case highlights the need to screen for secondary hypertension as early as possible. Finerenone may be effective for patients with PA who are not candidates for surgery and those not relieved after surgery.

Different Proteomic Profiles Regarding Antihypertensive Therapy in Preeclampsia Pregnant.

Preeclampsia (PE) is a hypertensive pregnancy syndrome associated with target organ damage and increased cardiovascular risks, necessitating antihypertensive therapy. However, approximately 40% of patients are nonresponsive to treatment, which results in worse clinical outcomes. This study aimed to compare circulating proteomic profiles and identify differentially expressed proteins among 10 responsive (R-PE), 10 nonresponsive (NR-PE) patients, and 10 healthy pregnant controls (HP). We also explored correlations between these proteins and clinical data. Plasma protein relative quantification was performed using mass spectrometry, followed by bioinformatics analyses with the UniProt database, PatternLab for Proteomics 4.0, and MetaboAnalyst software (version 6.0). Considering a fold change of 1.5, four proteins were differentially expressed between NR-PE and R-PE: one upregulated (fibronectin) and three downregulated (pregnancy-specific beta-1-glycoprotein 1, complement C4B, and complement C4A). Between NR-PE and HP, six proteins were differentially expressed: two upregulated (clusterin and plasmin heavy chain A) and four downregulated (apolipoprotein L1, heparin cofactor II, complement C4B, and haptoglobin-related protein). Three proteins were differentially expressed between R-PE and HP: one downregulated (transthyretin) and two upregulated (apolipoprotein C1 and hemoglobin subunit beta). These findings suggest a complex interplay of these proteins involved in inflammatory, immune, and metabolic processes with antihypertensive therapy responsiveness and PE pathophysiology.

Acute Declines in Estimated Glomerular Filtration Rate in Patients Treated With Benazepril and Hydrochlorothiazide Versus Amlodipine and Risk of Cardiovascular Outcomes.

BACKGROUND: Acute declines in estimated glomerular filtration rate (eGFR) occur commonly after starting angiotensin-converting enzyme inhibitors. Whether declines in eGFR that occur after simultaneously starting angiotensin-converting enzyme inhibitors with other antihypertensive agents modifies the benefits of these agents on cardiovascular outcomes is unclear. METHODS AND RESULTS: We identified predictors of acute declines in eGFR (>15% over 3 months) during randomization to benazepril plus amlodipine versus benazepril plus hydrochlorothiazide in the ACCOMPLISH (Avoiding Cardiovascular Events through Combination Therapy in Patients Living with Systolic Hypertension) trial. We then determined the relation between declines in eGFR (treated as a binary variable, ≤15% versus >15% and separately, as a restricted spline variable) and the composite risk of fatal and nonfatal cardiovascular events using Cox proportional hazards models. We included 10 714 participants (median age 68 years [Q1 63, Q3 73]), of whom 1024 reached the trial end point over median follow-up of 2.8 years. Predictors of acute declines in eGFR>15% over 3 months included assignment to hydrochlorothiazide (versus amlodipine) and higher baseline albuminuria. Overall, declines in eGFR ≥15% (versus <15%) were associated with a 26% higher hazard of cardiovascular outcomes (95% CI, 1.07-1.48). In spline-based analysis, risk for cardiovascular outcomes was higher in the hydrochlorothiazide arm at every level of decline in eGFR compared with the same magnitude of eGFR decline in the amlodipine arm. CONCLUSION: Combined use of benazepril and amlodipine remains superior to benazepril and hydrochlorothiazide for cardiovascular outcomes, regardless of the magnitude of the decline in eGFR that occurred with initiation of therapy.

Adherence to Antihypertensive Therapy and Its Determinants: A Systematic Review.

Hypertension is a globally prevalent condition, and low adherence to antihypertensive therapy is considered one of the main causes of poor blood pressure (BP) control. Non-adherence to antihypertensive treatment is a complex issue that can arise from various factors; however, gaining an understanding of this provides key targets for intervention strategies. This study aimed to provide an overview of the current status and recent developments regarding our understanding of the determinants of patients' adherence to antihypertensives. A systematic review was performed using the electronic databases MEDLINE/PubMed, Web of Science, Scientific Electronic Library Online (SciELO), and "Índex das Revistas Médicas Portuguesas", which included studies published between 2017 and 2021 following the PICOS model: (P) Adult patients with the diagnosis of primary hypertension, using at least one antihypertensive agent; (I) all interventions on both pharmacological and non-pharmacological level; (C) patient's adherence against their non-adherence; (O) changes in adherence to the therapeutic plan; and (S) any study design (except review articles) written in English, French, Spanish or Portuguese. Articles were reviewed by two researchers and their quality was assessed. Subsequently, determinants were classified according to their consistent or inconsistent association with adherence or non-adherence. Only 45 of the 635 reports identified met the inclusion criteria. Adherence was consistently associated with patient satisfaction with communication, patient-provider relationship, their treatment, and use of eHealth and mHealth strategies; a patient's mental and physical health, including depression, cognitive impairment, frailty, and disability, previous hospitalization, occurrence of vital events; drug treatment type and appearance; and unwillingness due to health literacy, self-efficacy, and both implicit and explicit attitudes towards treatment. There were discrepancies regarding the association of other factors to adherence, but these inconsistent factors should also be taken into account. In conclusion, the barriers to adherence are varied and often interconnected between socioeconomic, patient, therapy, condition, and healthcare system levels. Healthcare teams should invest in studying patients' non-adherence motives and tailoring interventions to individual levels, by using a multifaceted approach to assess adherence. Further research is needed to analyze the impact of implicit attitudes, the use of new technological approaches, and the influence of factors that are inconsistently associated with non-adherence, to understand their potential in implementing adherence strategies.

Mathematical modelling of the influence of ACE I/D polymorphism on blood pressure and antihypertensive therapy.

The angiotensin-converting enzyme (ACE) gene (ACE) insertion/deletion (I/D) polymorphism raises the possibility of personalising ACE inhibitor therapy to optimise its efficiency and reduce side effects in genetically distinct subgroups. However, the extent of its influence among these subgroups is unknown. Therefore, we extended our computational model of blood pressure regulation to investigate the effect of the ACE I/D polymorphism on haemodynamic parameters in humans undergoing antihypertensive therapy. The model showed that the dependence of blood pressure on serum ACE activity is a function of saturation and therefore, the lack of association between ACE I/D and blood pressure levels may be due to high ACE activity in specific populations. Additionally, in an extended model simulating the effects of different classes of antihypertensive drugs, we explored the relationship between ACE I/D and the efficacy of inhibitors of the renin-angiotensin-aldosterone system. The model predicted that the response of cardiovascular and renal parameters to treatment directly depends on ACE activity. However, significant differences in parameter changes were observed only between groups with high and low ACE levels, while different ACE I/D genotypes within the same group had similar changes in absolute values. We conclude that a single genetic variant is responsible for only a small fraction of heredity in treatment success and its predictive value is limited.

Statins As Anti-Hypertensive Therapy: A Systematic Review and Meta-Analysis.

Hypertension is the most prevalent condition in clinical practice. Hypertension, diabetes, and hypercholesterolaemia are major contributing factors to cardiovascular diseases. They commonly coexist in a single patient. Statins have been used as prominent medicines for the reduction of cardiovascular events. Statins have been shown to reduce blood pressure in patients with hypertension and have lipid-lowering properties in recent articles. Statins reduce blood pressure because of their impact on endothelial function, their interactions with the renin-angiotensin system, and their influence on major artery compliance. This meta-analysis aimed to ascertain the effectiveness and efficacy of statins for managing hypertension in patients with hypertension. Systematic searches were conducted on PubMed, Science Direct, Embase, Cochrane Library, and Google Scholar. Randomized controlled trials, systematic trials, and cohort studies were retrieved using keywords on statins and their use in patients with hypertension. Exclusion criteria included studies that were not in the English language, studies that did not include patients on statins with hypertension, studies that did not provide enough information, technical reports, opinions, or editorials, and studies involving patients < 18 years old. The inclusion criteria were randomized controlled trials, meta-analyses, adult patients aged > 18 years old, and studies that were freely available or through institutional login. This meta-analysis scrutinized 9361 randomized controlled trials, clinical trials, meta-analyses, and systematic reviews, of which 32 articles including 25 randomized controlled trials and seven meta-analyses were included in the final analysis. This meta-analysis of the role of statins in hypertensive patients aimed to determine the outcome of hypertension control along with antihypertensive medication. Our study showed that statins are useful in reducing both systolic and diastolic blood pressure. We used a heterogeneous model for analysis due to variations in the study characteristics. The I2 value was 0.33 (0.76, 0.10) for systolic blood pressure and 0/88 (0.86, 0.90) for diastolic blood pressure. The I2 value for the seven meta-analyses included in the study was 1.79 (2.88, 0.69).

Lasix for the prevention of de novo postpartum hypertension: a randomized placebo-controlled trial (LAPP Trial).

BACKGROUND: Birthing people with de novo postpartum hypertensive disorders continue to be among the populations at highest risk for severe maternal morbidity. Randomized controlled trials demonstrate a benefit of oral loop diuretics in decreasing postpartum hypertensive morbidity in patients with an antenatal diagnosis of preeclampsia. It is not known whether this same therapy benefits patients at risk for new-onset postpartum hypertension. OBJECTIVE: This study aimed to evaluate whether oral furosemide can reduce the risk for de novo postpartum hypertension among high-risk birthing people by reducing postdelivery blood pressure. STUDY DESIGN: From October 2021 to April 2022, we conducted a randomized triple-masked placebo-controlled clinical trial of individuals at high risk for de novo postpartum hypertension at a single university-based tertiary care medical center. A total of 82 postpartum patients with no antenatal diagnosis of chronic hypertension or a hypertensive disorder of pregnancy who were at high risk for the development of de novo postpartum hypertension based on a prespecified risk factor algorithm were enrolled after childbirth. The participants were randomly assigned in a 1:1 ratio to a 5-day course of 20-mg oral furosemide daily or identical-appearing placebo starting within 8 hours of delivery. Participants were followed for 6 weeks postpartum using Bluetooth-enabled remote blood pressure monitoring and electronic surveys. The primary outcome was mean arterial pressure averaged over the 24 hours before discharge or the 24 hours before antihypertensive therapy initiation. The study was powered to detect a 5 mm Hg difference in average mean arterial pressure (standard deviation, 6.4 mm Hg) with 90% power at an alpha of 0.05, requiring a sample size of 41 per group. Secondary outcomes included the rate of de novo postpartum hypertension, readmission data, other measures of hypertensive and maternal morbidity, breastfeeding data, and drug-related neonatal outcomes. RESULTS: The primary outcome was assessed in 80 of the 82 participants. Baseline characteristics were similar between the groups. There was no significant difference in average mean arterial pressure in the 24 hours before discharge (or antihypertensive initiation) in the furosemide group (88.9±7.4 mm Hg) compared with the placebo group (86.8±7.1 mm Hg; absolute difference, 2.1 mm Hg; 95% confidence interval, -1.2 to 5.3). Of the 79 participants for whom secondary outcomes were assessed, 10% (n=8) developed de novo postpartum hypertension and 9% (n=7) were initiated on antihypertensive therapy. Rates were not significantly different between the groups (P=.71 and P>.99, respectively). CONCLUSION: De novo postpartum hypertension is a common phenomenon among at-risk patients, warranting close monitoring for severe hypertension and other maternal morbidity. There is insufficient evidence to suggest that furosemide reduces average mean arterial pressure in the 24 hours before discharge from the delivery hospitalization (or antihypertensive medication initiation) compared with placebo.

Pre-Stroke Antihypertensive Therapy Affects Stroke Severity and 3-Month Outcome of Ischemic MCA-Territory Stroke.

OBJECTIVES: Whether different antihypertensive drug classes in high blood pressure (HBP) pre-stroke treatment affect dynamic cerebral autoregulation (dCA), stroke severity, and outcome. METHODS: Among 337 consecutive ischemic stroke patients (female 102; median age 71 years [interquartile range, [IQR 60; 78]; NIHSS median 3 [IQR 1; 6]) with assessment of dCA, 183 exhibited the diagnosis of HBP. dCA parameters' gain and phase were determined by transfer function analysis of spontaneous oscillations of blood pressure and cerebral blood flow velocity. RESULTS: Patients used beta-blockers (n = 76), calcium channel blockers (60), diuretics (77), angiotensin-converting enzyme inhibitors (59), or angiotensin-1 receptor blockers (79), mostly in various combinations of two or three drug classes. dCA parameters did not differ between the non-HBP and the different HBP medication groups. Multinomial ordinal logistic regression models revealed that the use of diuretics decreased the likelihood of a less severe stroke (odds ratio 0.691, 95% CI 0.493; 0.972; p = 0.01) and that beta-blockers decreased the likelihood of a better modified Rankin score at 3 months (odds ratio 0.981, 95% CI 0.970; 0.992; p = 0.009). Other independent factors associated with stroke outcome were penumbra and infarct volume, treatment with mechanical thrombectomy, and the initial National Institute of Health Stroke Scale score. INTERPRETATION: In this cohort of ischemic minor to moderate stroke patients, pre-stroke antihypertensive treatment with diuretics was associated with a more severe neurological deficit on admission and pre-stroke treatment with beta-blockers with a poorer 3-month outcome. The antihypertensive drug class used pre-stroke did not impact dCA.

Comparing Intraocular Pressure, Ocular Blood Flow, and Retinal Nerve Fiber Layer Thickness in Early and Chronic Hypertensives With Normotensives.

PURPOSE: To compare blood pressure (BP), intraocular pressure (IOP), ophthalmic artery flow (OAF) velocity, retinal nerve fiber layer (RNFL) thickness, and visual fields in newly diagnosed hypertension (HT) patients (before treatment), chronic HT (on antihypertensive medications >5 years) and normotensives. METHODS: A prospective, cross-sectional study at a tertiary care centre in India. Three groups of 45 patients each: group 1 - early HT, group 2 - chronic HT, and Group 3 - normotensives, underwent evaluation of BP, IOP by Goldmann applanation tonometry (GAT), OAF velocity by transcranial doppler (TCD), RNFL analysis by spectral-domain optical coherence tomography (SD-OCT), and visual fields. RESULTS: The BP was highest in early HT > chronic HT > normotensives (p < 0.001). The IOP of early HT, chronic HT, and normotensives were 15.87 ± 2.19 mmHg, 13.47 ± 1.92 mmHg, and 15.67 ± SD 1.75 mmHg (p < 0.001). The OAF velocity [peak systolic velocity (PSV), end-diastolic velocity (EDV) in cm/sec] was lowest in chronic HT (30.80 ± 7.05, 8.58 ± 1.58) < early HT (35.47 ± 5.34, 10.02 ± 1.74) < normotensives (36.29 ± 4.43, 10.44 ± 2.29), (p < 0.001). The average RNFL thickness was significantly lower in chronic HT (p = 0.022). The PSV, EDV, and MFV showed significant correlation with IOP (r = 0.247, p = 0.004; r = 0.206, p = 0.016; r = 0.266, p = 0.002) and average RNFL thickness (r = 0.309, p= <0.001; r = 0.277, p = 0.001; r = 0.341, p < 0.001). CONCLUSIONS: Patients with chronic HT demonstrated the lowest retrobulbar flows, IOP and lower RNFL measurements. Lower ocular perfusion may be associated with lower IOP and may be a risk factor for end-organ damage (RNFL) independent of IOP.

Reliability and Time Course of Postexercise Hypotension during Exercise Training among Adults with Hypertension.

Postexercise hypotension (PEH), or the immediate decrease in blood pressure (BP) lasting for 24 h following an exercise bout, is well-established; however, the influence of exercise training on PEH dynamics is unknown. This study investigated the reliability and time course of change of PEH during exercise training among adults with hypertension. PEH responders (n = 10) underwent 12 weeks of aerobic exercise training, 40 min/session at moderate-to-vigorous intensity for 3 d/weeks. Self-measured BP was used to calculate PEH before and for 10 min after each session. The intraclass correlation coefficient (ICC) and Akaike Information Criterion (AIC) determined PEH reliability and goodness-of-fit for each week, respectively. Participants were obese (30.6 ± 4.3 kg∙m-2), middle-aged (57.2 ± 10.5 years), and mostly men (60%) with stage I hypertension (136.5 ± 12.1/83.4 ± 6.7 mmHg). Exercise training adherence was 90.6 ± 11.8% with 32.6 ± 4.2 sessions completed. PEH occurred in 89.7 ± 8.3% of these sessions with BP reductions of 9.3 ± 13.1/3.2 ± 6.8 mmHg. PEH reliability was moderate (ICC ~0.6). AIC analysis revealed a stabilization of maximal systolic and diastolic BP reductions at 3 weeks and 10 weeks, respectively. PEH persisted throughout exercise training at clinically meaningful levels, suggesting that the antihypertensive effects of exercise training may be largely due to PEH. Further studies in larger samples and under ambulatory conditions are needed to confirm these novel findings.

Correlates of Spontaneous Blood Pressure Reduction Following Severe Inpatient Hypertension Development.

BACKGROUND: Severe hypertension (sHTN) is prevalent in 10% of hospitalized patients and treatment guidelines are lacking. As such, patients who develop sHTN might unnecessarily receive antihypertensive medications which could lead to worse outcomes. Our goal was to investigate correlates of spontaneous blood pressure (BP) reduction to help guide future treatment decisions and avoid harm associated with aggressive BP treatment. METHODS: This is a retrospective cohort study of hospitalized adults between 2016 and 2020 who developed sHTN, SBP >180 or DBP >110 mm Hg, after admission. Spontaneous BP reduction was defined as a SBP <160 and a DBP <100 mm Hg achieved within 3 h of sHTN in the absence of antihypertensive therapy. Multivariable logistic regression was used to identify correlates of spontaneous BP reduction. RESULTS: Of the 12,825 patients who developed sHTN, 44.2% had spontaneous BP reduction. After adjustment, we found that patients most likely to experience a BP drop received steroids before onset of sHTN (Odds ratio [OR]: 1.3 [1.09, 1.56]), had higher potassium levels on admission (OR: 1.2 [1.09, 1.24]) and were more likely to have a history of chronic pulmonary disease (OR: 1.1 [1.01, 1.18]) or cardiac arrythmia (OR: 1.1 [1.01, 1.18]). While numerically different, these differences were not clinically relevant. CONCLUSIONS: Our findings indicate that almost half the patients who develop sHTN have spontaneous BP reduction. Conventional clinical and demographic characteristics were not strong predictors of spontaneous BP reduction following sHTN development. More research is needed to confirm our findings and help guide treatment of sHTN.

Effect of different anti-cardiovascular disease treatments on the severity of obstructive sleep apnea.

Obstructive sleep apnea (OSA) and cardiovascular co-morbidities have a mutually reinforcing effect, but existing studies have focussed only on the improvement of the associated co-morbidities by treatment for OSA. To provide fresh guidelines for the treatment of OSA from a co-morbidity standpoint, we conducted a systematic search of Web of Science, PubMed, EMBASE, and the Cochrane Library for articles published from inception up to 2 May 2023. Fourteen original studies of patients with OSA with cardiovascular co-morbidities and who received related treatment were included in the analysis. We found that diuretic treatment can reduce the apnea-hypopnea index in patients with OSA and hypertension (-19.41/h, p = 1.0 × 10-5 ), aldosterone-angiotensin inhibitors also have a 9.19/h reduction (p = 0.003), while the effect of renal sympathetic denervation is insignificant (-2.32/h, p = 0.19). The short-term treatment (<4 weeks) did not show an improvement (-2.72/h, p = 0.16), while long-term treatment (>4 weeks) produced surprising outcomes (-12.78/h, p = 0.002). Patients with milder disease (baseline AHI < 35/h) had insignificant improvements (-1.05/h, p = 0.46), whereas those with more severe disease (baseline AHI > 35/h) could achieve satisfactory outcomes (-14.74/h, p < 0.00001). In addition, it also showed some improvement in the oxygen desaturation index and blood oxygen. Our results support the additional benefit of antihypertensive treatment for OSA symptoms, and the efficacy can be affected by different therapy, treatment duration, and severity levels. It could be useful in developing clinical therapy, educating patients, and exploring interaction mechanisms. The proposal was registered with PROSPERO (CRD42022351206).

A Successfully Treated Case of Posterior Ischemic Optic Neuropathy That Developed during Antihypertensive Therapy for Hypertensive Emergency.

A 33-year-old woman developed hypertensive emergency (268/168 mmHg) with renal failure and hypertensive retinopathy. Four hours after the initiation of antihypertensive therapy with the continuous infusion of nicardipine, her blood pressure (BP) decreased to 168/84 mmHg; however, the patient developed blindness. She was diagnosed with posterior ischemic optic neuropathy (PION). Her BP was maintained at approximately 175/90 mmHg until her vision improved. Olmesartan was initiated on day 13, and her BP decreased to approximately 135/95 mmHg without the re-exacerbation of vision loss. Although the prognosis of PION is poor, its early diagnosis and gradual antihypertensive therapy may help preserve the patient's vision.

Pharmacogenomics of Preeclampsia therapies: Current evidence and future challenges for clinical implementation.

Preeclampsia is a pregnancy-specific disorder, and it is a leading cause of maternal and perinatal morbidity and mortality. The application of pharmacogenetics to antihypertensive agents and dose selection in women with preeclampsia is still in its infancy. No current prescribing guidelines from the clinical pharmacogenetics implementation consortium (CPIC) exist for preeclampsia. Although more studies on pharmacogenomics are underway, there is some evidence for the pharmacogenomics of preeclampsia therapies, considering both the pharmacokinetic (PK) and pharmacodynamic (PD) properties of drugs used in preeclampsia. It has been revealed that the CYP2D6*10 variant is significantly higher in women with preeclampsia who are non-responsive to labetalol compared to those who are in the responsive group. Various genetic variants of PD targets, i.e., NOS3, MMP9, MMP2, TIMP1, TIMP3, VEGF, and NAMPT, have been investigated to assess the responsiveness of antihypertensive therapies in preeclampsia management, and they indicated that certain genetic variants of MMP9, TIMP1, and NAMPT are more frequently observed in those who are non-responsive to anti-hypertensive therapies compared to those who are responsive. Further, gene-gene interactions have revealed that NAMPT, TIMP1, and MMP2 genotypes are associated with an increased risk of preeclampsia, and they are more frequently observed in the non-responsive subgroup of women with preeclampsia. The current evidence is not rigorous enough for clinical implementation; however, an institutional or regional-based retrospective analysis of audited data may help close the knowledge gap during the transitional period from a traditional approach (a "one-size-fits-all" strategy) to the pharmacogenomics of preeclampsia therapies.

[Relationship between the pain severity, use of non-steroidal anti-inflammatory drugs and blood pressure in elective large joint arthroplasty of the lower extremities].

AIM: To evaluate the changes in blood pressure (BP), the severity of pain syndrome and non-steroidal anti-inflammatory drugs (NSAIDs) use patterns in patients hospitalized for elective arthroplasty of large joints of the lower extremities during the postoperative period. MATERIALS AND METHODS: This study included 374 patients. In all patients, medical history, antihypertensive therapy and history of NSAIDs usage were collected, BP was measured, and the severity of pain was assessed via a 10-point scale before surgery, as well as 1 and 3 months after arthroplasty. RESULTS: The study included 132 (35.3%) males and 242 (64.7%) females. Among these, 289 (77.3%) patients had hypertension [grade 1 - 35 patients, grade 2 - 136 patients, grade 3 - 118 (25.0%) patients]; 280 (74.9%) patients were taking NSAIDs (121 - daily, 135 - 2-3 times per week). The median pain severity before surgery was 8 points [7; 9], 1 month after surgery - 2 points [1; 4], 3 months after surgery - 1 point [0; 3]. At 1 month after arthroplasty, 23 (7.9%) patients reported a decrease in BP. In 17 (5.9%) patients, correction of previously prescribed antihypertensive therapy with a decrease in drug doses was required. At 1 month after arthroplasty, 256 patients discontinued NSAIDs. The analysis of the relationship between the severity of pain, NSAIDs use and the level of BP revealed a significant effect of pain syndrome (p<0.0001) and the use of NSAIDs (p=0.014). CONCLUSION: In the population of patients with elective arthroplasty of large joints of the lower extremities, a significant incidence of hypertension and a high prevalence of NSAIDs use are noted. During the postoperative period, a significant trend towards a decrease in the severity of pain was found, as well as the relationship of pain and NSAIDs with a decrease in BP.

Features and Comparative Characteristics of Fucosylated Glycans Expression in Endothelial Glycocalyx of Placental Terminal Villi in Patients with Preeclampsia Treated with Different Antihypertensive Regimens.

Antihypertensive therapy is an essential part of management of patients with preeclampsia (PE). Methyldopa (Dopegyt®) and nifedipine (Cordaflex®) are basic medications of therapy since they stabilize blood pressure without affecting the fetus. Their effect on the endothelium of placental vessels has not yet been studied. In this study, we analyzed the effect of antihypertensive therapy on the expression of fucosylated glycans in fetal capillaries of placental terminal villi in patients with early-onset PE (EOPE) and late-onset PE (LOPE), and determined correlation between their expression and mother's hemodynamic parameters, fetoplacental system, factors reflecting inflammatory response, and destructive processes in the endothelial glycocalyx (eGC). A total of 76 women were enrolled in the study: the comparison group consisted of 15 women with healthy pregnancy, and the main group comprised 61 women with early-onset and late-onset PE, who received one-component or two-component antihypertensive therapy. Hemodynamic status was assessed by daily blood pressure monitoring, dopplerometry of maternal placental and fetoplacental blood flows, and the levels of IL-18, IL-6, TNFα, galectin-3, endocan-1, syndecan-1, and hyaluronan in the blood of the mother. Expression of fucosylated glycans was assessed by staining placental sections with AAL, UEA-I, LTL lectins, and anti-LeY MAbs. It was found that (i) expression patterns of fucosylated glycans in eGC capillaries of placental terminal villi in EOPE and LOPE are characterized by predominant expression of structures with a type 2 core and have a similar pattern of quantitative changes, which seems to be due to the impact of one-component and two-component antihypertensive therapy on their expression; (ii) correlation patterns indicate interrelated changes in the molecular composition of eGC fucoglycans and indicators reflecting changes in maternal hemodynamics, fetoplacental hemodynamics, and humoral factors associated with eGC damage. The presented study is the first to demonstrate the features of placental eGC in women with PE treated with antihypertensive therapy. This study also considers placental fucoglycans as a functional part of the eGC, which affects hemodynamics in the mother-placenta-fetus system.

[Arterial hypertension and cognitive impairment. Neurologist's view]. / Arterial'naya gipertenziya i kognitivnye narusheniya. Vzglyad nevrologa.

The article presents a review of the literature on the relationship of cognitive impairment (CI) with arterial hypertension (AH). The pathogenetic mechanisms AH are characterized by the development of cerebral microangiopathy. Antihypertensive therapy (AHT) should take into account violations of autoregulation of cerebral blood flow in cerebrovascular disease and critical stenoses of large cerebral arteries, especially in fragile patients older than 80 years. The importance of AHT focused on the level of cerebral perfusion blood pressure, the severity of CI and the physical functioning of patients is emphasized. Neurocytoprotective therapy is recommended for correction of CI.

A Renal Artery Stenting Case: Support for Increased Use of Drug-Eluting Stents.

Fibromuscular dysplasia is a rare, systemic arteriovascular disease that often affects the renal arteries. Balloon angioplasty is recommended for uncontrolled hypertension and compromised renal function; stenting is a bailout option. Drug-eluting stents have been suggested in case reports. We report the successful intervention with an everolimus-coated stent in a very young patient. The patient was followed for 2 years after placing the stent. The success of this case suggests that drug-eluting stents should be used more frequently in comparable situations.

The HOPE Asia Network consensus on blood pressure measurements corresponding to office measurements: Automated office, home, and ambulatory blood pressures.

For adopting recently introduced hypertension phenotypes categorized using office and out of office blood pressure (BP) for the diagnosis of hypertension and antihypertension drug therapy, it is mandatory to define the corresponding out of office BP with the specific target BP recommended by the major guidelines. Such conditions include white-coat hypertension (WCH), masked hypertension (MH), white-coat uncontrolled hypertension (WUCH), and masked uncontrolled hypertension (MUCH). Here, the authors review the relevant literature and discuss the related issue to facilitate the use of corresponding BPs for proper diagnosis of WCH, MH, WUCH, and MUCH in the setting of standard target BP as well as intensive target BP. The methodology of deriving the corresponding BP has evolved from statistical methods such as standard deviation, percentile value, and regression to an outcome-based approach using pooled international cohort study data and comparative analysis in randomized clinical trials for target BPs such as the SPRINT and STEP studies. Corresponding BPs to 140/90 and 130/80 mm Hg in office BP is important for safe and strict achievement of intensive BP targets. The corresponding home, daytime, and 24-h BPs to 130/80 mm Hg in office BP are 130/80, 130/80, and 125/75 mm Hg, respectively. However, researchers have found some discrepancies among the home corresponding BPs. As tentative criterion for de-escalation of antihypertensive therapy as shown in European guidelines was 120 mm Hg in office BP, corresponding home, daytime, and 24-h systolic BPs to 120 mm Hg in office systolic BP are 120, 120, and 115 mm Hg, respectively.
