Background: Elevated soluble stimulating factor 2 (sST2) level is observed in cardiovascular diseases, such as heart failure and acute coronary syndrome, which reflects myocardial fibrosis and hypertrophy, indicating adverse clinical outcomes. However, the association between sST2 and hypertensive heart disease are less understood. This study aimed to determine the relationship of sST2 with left ventricular hypertrophy (LVH) and geometric remodeling in essential hypertension (EH)., Methods: We enrolled 483 patients (aged 18-80 years; 51.35% female). sST2 measurements and echocardiographic analyses were performed., Results: Stepwise multiple linear regression analysis showed significant associations among sST2, left ventricular (LV) mass, and LV mass index. The prevalence of LVH and concentric hypertrophy (CH) increased with higher sST2 grade levels (P for trend < 0.05). Logistic regression analysis suggested that the highest tertile of sST2 was significantly associated with increased LVH risk, compared with the lowest tertile (multivariate-adjusted odds ratio [OR] of highest group: 6.61; P < 0.001). Similar results were observed in the left ventricular geometric remodeling; the highest tertile of sST2 was significantly associated with increased CH risk (multivariate-adjusted OR of highest group: 5.80; P < 0.001). The receiver operating characteristic analysis results revealed that sST2 had potential predictive value for LVH (area under the curve [AUC]: 0.752, 95% confidence interval [CI]: 0.704-0.800) and CH (AUC: 0.750, 95% CI: 0.699-0.802) in patients with EH., Conclusions: High sST2 level is strongly related to LVH and CH in patients with EH and can be used as a biomarker for the diagnosis and risk assessment of hypertensive heart disease., Clinical Trials Registration: Trial Number ChiCTR2400082764., (© The Author(s) 2024.

Background: The triglyceride-glucose (TyG) index is regarded as an independent predictor of cardiovascular disease consequences and a reliable surrogate measure of insulin resistance (IR). However, the correlation analysis between triglyceride glucose index and heart failure with preserved ejection fraction in patients with essential hypertension remains unknown., Methods: A single-center, retrospective study was conducted with patients diagnosed with essential hypertension at the First Affiliated Hospital of Xinjiang Medical University, from December 2018 to September 2020. Participants were selected based on specific inclusion and exclusion criteria, with their clinical data and laboratory tests collected. The study employed Spearman's correlation analysis, logistic regression models, restricted cubic spline plots, and receiver operating characteristic (ROC) curves to investigate the relationships between the TyG index and HFpEF., Results: Out of 1,602 enrolled hypertensive patients, 992 were included in the analysis after applying exclusion criteria. Patients were categorized into tertiles based on the TyG index, which showed that patients in the highest tertile had characteristics associated with a higher risk of HFpEF, including age, body mass index (BMI), systolic blood pressure (SBP), N-terminal pro-B-type natriuretic peptide (NT-proBNP), and left ventricular mass index (LVMI). A significant, independent association between the TyG index and HFpEF was confirmed, with an odds ratio (OR) of 5.127 (95% CI [3.894-6.856]). Furthermore, an S-shaped nonlinear relationship was observed between the TyG index and the incidence of HFpEF (nonlinear p < 0.001). TyG index (AUC: 0.824, 95% CI [0.795-0.854]), NT-proBNP (AUC: 0.840, 95% CI [0.816-0.864]), and LVMI (AUC: 0.847, 95% CI [0.820-0.875]) showed good predictive ability for HFpEF. In addition, the TyG+LVMI combination demonstrated the strongest predictive ability (AUC: 0.907, 95% CI [0.887-0.927])., Conclusion: The study underscores a significant association between IR, as indicated by the TyG index, and the development of HFpEF in hypertensive patients. It highlights the critical role of metabolic dysfunction in the pathophysiology of HFpEF, advocating for a broader perspective on cardiovascular risk management., Competing Interests: The authors declare that they have no competing interests., (© 2024 Shan et al.)

Homocysteine (Hcy) is a sulphur-containing nonessential amino acid derived from the intermediate metabolites of methionine. Methionine is obtained from dietary proteins, such as poultry, meat, eggs, seafood, and dairy products. Abnormalities in Hcy metabolic pathways, deficiencies in dietary methionine, folate, and vitamins B12, B6, and B2 and genetic defects, polymorphisms, or mutations in Hcy metabolism-related enzymes may lead to an increase in plasma Hcy levels. Generally, a plasma Hcy level higher than 10 or 15 μmol/L has been defined as hyperhomocysteinemia (HHcy). An individual with essential hypertension complicated with HHcy is considered to have H-type hypertension (HTH). Currently, HHcy is considered a novel independent risk factor for various cardiovascular diseases. To provide a useful reference for clinicians, the research progress on Hcy, HHcy, and HTH in recent years was systematically reviewed here, with a focus on the source and metabolic pathways of Hcy, plasma Hcy levels and influencing factors, detection methods for plasma Hcy levels, relationship between Hcy concentration and hypertension, pathogenesis of HTH, cardiovascular complications of HTH, and treatment of HTH., Competing Interests: Conflict of interest: none declared., (© The Author(s) 2024.

Background and Aims: H-type hypertension is essential hypertension combined with high homocysteine, and both synergistically increase the risk of cardiovascular and cerebrovascular events. The aim of this study was to investigate the risk factors of H-type hypertension in Tibetan plateau population and correlation with MTHFR C677T gene., Methods and Results: A multi-stage cluster random sampling method was used to select the research subjects in Tibet Autonomous Region from June 2020 to November 2021. Among Tibetans, the incidence of H-type hypertension accounted for 84.31% of hypertensive patients. The logistic regression analysis demonstrated that age, uric acid (UA), triglyceride (TG) and low-density lipoprotein cholesterol (LDL-C) were risk factors for the prevalence of H-type hypertension, the OR (95% CI) was 1.083(1.073-1.094), 1.002(1.001-1.004), 1.240(1.050-1.464) and 2.274(1.432-3.611), respectively. MTHFR C677T TT genotype patients with H-type hypertension OR (95% CI) was 1.629(1.004-2.643). Based on this, a nomogram model was established, and the reliability of the model was proved by area under ROC curve, Brier score and average absolute error. The model's results indicate that for every five years of age, the score increases by 6 points; for a 2mmol/L increase in TG, the score increases by 5.5 points; for a 1mmol/L increase in LDL-C, the score increases by 10 points; and individuals with the TT genotype receive 8 points. The higher the score, the greater the risk of disease., Conclusion: The MTHFR C677T TT genotype is a risk locus for Tibetan patients with H-type hypertension, with age, TG, and LDL-C were identified as risk factors for the disease., (© 2024.

Background: Hypertension is the leading risk factor for cardiovascular disease worldwide. Patients with blood pressure (BP) response to dietary sodium reduction are referred to as "salt sensitive." Salt sensitivity (SS) might be due to differences in sodium storage capacity and the erythrocyte SS examines this capacity of the red blood cells. This study aimed to test the effect of a self-performed sodium reduced diet on BP in patients with essential hypertension and examine whether erythrocyte SS predicts SS., Methods and Results: Seventy-two patients with hypertension were included and randomized 2:1 to either sodium reduction or a control group for 4 weeks. Blood samples, 24-hour BP measurement, and 24-hour urine collection were performed before and after. The intervention group received advice on how to lower sodium intake. Urinary sodium excretion decreased 66 mmol (95% CI, -96 to -37 mmol) in the intervention group compared with the control group. Systolic 24-hour BP decreased 9 mm Hg after low-sodium diet compared with the control group (95% CI, -13 to -4 mm Hg). Similarly, the difference in reduction in diastolic BP between the groups was 5 mm Hg (95% CI, -8 to -1 mm Hg). We found no correlation between erythrocyte SS at baseline and decrease in 24-hour BP, neither systolic nor diastolic ( P =0.66 and P  = 0.84)., Conclusions: Self-performed sodium reduction was feasible and led to decrease in 24-hour BP of 9/5 mm Hg compared with a control group. The erythrocyte SS did not correlate to the change in BP after lowering sodium intake., Registration: URL: https://clinicaltrials.gov; Unique Identifier: NCT05165823.

Background: This study aimed to investigate the potential association between the circadian rhythm of blood pressure and deceleration capacity (DC)/acceleration capacity (AC) in patients with essential hypertension., Methods: This study included 318 patients with essential hypertension, whether or not they were being treated with anti-hypertensive drugs, who underwent 24-hour ambulatory blood pressure monitoring (ABPM). Patients were categorized into three groups based on the percentage of nocturnal systolic blood pressure (SBP) dipping: the dipper, non-dipper and reverse dipper groups. Baseline demographic characteristics, ambulatory blood pressure monitoring parameters, Holter recordings (including DC and AC), and echocardiographic parameters were collected., Results: In this study, the lowest DC values were observed in the reverse dipper group, followed by the non-dipper and dipper groups (6.46 ± 2.06 vs. 6.65 ± 1.95 vs. 8.07 ± 1.79 ms, P < .001). Additionally, the AC gradually decreased (-6.32 ± 2.02 vs. -6.55 ± 1.95 vs. -7.80 ± 1.73 ms, P < .001). There was a significant association between DC (r = .307, P < .001), AC (r=-.303, P < .001) and nocturnal SBP decline. Furthermore, DC (β = 0.785, P = .001) was positively associated with nocturnal SBP decline, whereas AC was negatively associated with nocturnal SBP (β = -0.753, P = .002). By multivariate logistic regression analysis, deceleration capacity [OR (95% CI): 0.705 (0.594-0.836), p < .001], and acceleration capacity [OR (95% CI): 1.357 (1.141-1.614), p = .001] were identified as independent risk factors for blood pressure nondipper status. The analysis of ROC curves revealed that the area under the curve for DC/AC in predicting the circadian rhythm of blood pressure was 0.711/0.697, with a sensitivity of 73.4%/65.1% and specificity of 66.7%/71.2%., Conclusions: Abnormal DC and AC density were correlated with a blunted decline in nighttime SBP, suggesting a potential association between the circadian rhythm of blood pressure in essential hypertension patients and autonomic nervous dysfunction., (© 2024.

This study aimed to elucidate the clinical diagnostic value of plasma catecholamines and their metabolites for pheochromocytoma and paraganglioma (PPGL)-induced secondary hypertension using ultraperformance liquid chromatography-mass spectrometry (UPLC-MS/MS). The study population included 155 patients with PPGL that were divided into the PPGL with hypertension (n = 79) and a PPGL without hypertension (n = 76) groups, and 90 healthy volunteers and 90 patients with primary hypertension as the control groups. UPLC-MS/MS was performed to detect plasma levels of catecholamines and their metabolites, including dopamine, vanillylmandelic acid (VMA), norepinephrine, metanephrine, and normetanephrine. Receiver operating characteristic curves were generated to analyze the diagnostic value of the plasma levels of catecholamines and their metabolites in PPGL-induced secondary hypertension. Patients in the primary hypertension and PPGL without hypertension groups had higher levels of dopamine, VMA, norepinephrine, metanephrine, and normetanephrine than patients in the normal group (all p < .05). On the other hand, patients in the PPGL with hypertension group had higher levels of dopamine, VMA, norepinephrine, metanephrine, and normetanephrine than patients in the normal, primary hypertension, and PPGL without hypertension groups (all p < .05). Collectively, our findings showed that dopamine, VMA, norepinephrine, metanephrine, and normetanephrine are all effective biomarkers for the diagnosis of PPGL and PPGL-induced secondary hypertension., (© 2024 The Authors.

Background: To explore the diagnostic accuracy and the optimal cutoff value between the saline infusion test (SIT) and captopril challenge test (CCT) [including the value and suppression of plasma aldosterone concentration (PAC)] for primary aldosteronism (PA) diagnosing., Methods: A total of 318 patients with hypertension were consecutively enrolled, including 126 patients with PA and 192 patients with essential hypertension (EH), in this observational study. The characteristics of patients and laboratory examinations were collected and compared. The comparison between SIT and CCT was carried by drawing the receiver operator characteristic curve (ROC) and calculating the area under the curve (AUC) to explore the diagnostic accuracy and the optimal cutoff value., Results: The average age was 51.59 ± 10.43 in the PA group and 45.72 ± 12.44 in the EH group ( p <0.05). The optimal cutoff value was 10.7 ng/dL for post-CCT PAC, 6.8 ng/dL for post-SIT PAC, and 26.9% for suppression of post-CCT PAC. The diagnostic value of post-CCT PAC was the highest with 0.831 for the AUC and 0.552 for the Youden index. The optimal cutoff value for patients who were <50 years old was 11.5 ng/dL for post-CCT PAC and 8.4 ng/dL for post-SIT PAC. The suppression of post-CCT PAC turned to 18.2% for those of age 50 or older., Conclusion: Compared with SIT, CCT had a higher diagnostic value when post-CCT PAC was used as the diagnostic criterion in Chinese people, while the selection of diagnostic thresholds depended on patient age., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Sun, Gong, Yu, Yang, Zhang, Jiang and Song.)

Background: This case-control study aimed to determine whether there were differences between patients with essential hypertension with accessory renal arteries (ARAs) and those without ARAs., Methods and Results: The enrolled patients with essential hypertension were divided into the ARA group (n=200) and control group without ARAs (n=238). After propensity matching, 394 patients (197 in each of the 2 groups), were included. The 24-hour BP (4.33/2.43 mm Hg) and daytime BP (4.48/2.61 mm Hg) of patients in the ARA group were significantly higher than those of the control group ( P <0.05). The flow-mediated dilation was lower in the ARA group (5.98±2.70 versus 5.18±2.66; P <0.05). In correlation analysis, the horizontal plasma aldosterone concentration had the highest correlation with 24-hour, daytime, and nighttime systolic BP ( r =0.263, 0.247, and 0.243, respectively; P <0.05) and diastolic BP ( r =0.325, 0.298, and 0.317, respectively; P <0.05). As for multivariate regression analysis, plasma aldosterone concentration was a significant risk factor for elevated 24-hour, daytime, and nighttime systolic BP (β=0.249 [95% CI, 0.150-0.349], 0.228 [95% CI, 0.128-0.329], and 0.282 [95% CI, 0.187-0.377], respectively; P <0.05) and elevated diastolic BP (β=0.289 [95% CI, 0.192-0.385], 0.256 [95% CI, 0.158-0.353], and 0.335 [95% CI, 0.243-0.427], respectively; P <0.05). Direct renin concentration was also a risk factor for 24-hour and daytime BPs, whereas heart rate was a risk factor correlated with 24-hour, daytime, and nighttime diastolic BP (all P <0.05). For the mixed-effects model for repeated measures, the results were similar to results of the multivariate regression analysis (all P <0.05)., Conclusions: ARAs could contribute a higher BP of patients with essential hypertension and might promote the development of essential hypertension. The mechanism might be related to overactivation of the renin-angiotensin-aldosterone system and sympathetic nervous system.

This study aimed to assess the efficacy and safety of esaxerenone (CS-3150) in treating primary hypertension. PubMed (Medline), Cochrane Central Register of Controlled Trials (CENTRAL), and Embase databases were searched for articles published until April 18, 2023. The outcomes included were diastolic blood pressure (DBP), systolic blood pressure (SBP), 24 h DBP, 24 h SBP, and adverse events. The meta-analysis was conducted using RevMan 5.3. This study included three trials. CS-3150 5 mg had a greater effect on lowering the SBP, DBP, 24 h SBP, and 24 h DBP than either CS-3150 2.5 mg or eplerenone 50 mg. In contrast, CS-3150 2.5 mg and eplerenone 50 mg showed no significant difference in lowering DBP, SBP, 24 h DBP, and 24 h SBP. Moreover, adverse events occurred at comparable rates in the three groups. CS-3150 (especially CS-3150 5 mg) is an effective and safe treatment for primary hypertension; which can reduce blood pressure and alleviate hypertensive symptoms., (© 2024. The Author(s).)

Objective: To investigate the association between β 1 adrenergic receptor autoantibodies ( β 1-AA) and angiotensin II type-1 receptor autoantibodies (AT1-AA) and cardiac function in patients with hypertension complicated with left ventricular diastolic function limitation., Methods: A total of 120 patients with essential hypertension who were not taking drug treatment and were hospitalised in the Department of Cardiology at the authors' hospital from April 2018 to December 2018 were enrolled in this study and divided into a diastolic dysfunction group (65 cases) and a normal diastolic group (55 cases) according to their left ventricular diastolic function. The levels of cardiac parameters, β 1-AA, AT1-AA, and other indicators were compared. Logistic regression analysis was used to analyse the related factors affecting left ventricular diastolic dysfunction (LVDD). The diagnostic efficacy of related factors in the diagnosis of diastolic dysfunction was evaluated., Results: Univariate analysis demonstrated that the left ventricular posterior wall diameter (10.29 ± 1.23 vs. 9.12 ± 1.53), left ventricular systolic dysfunction (10.56 ± 1.37 vs. 9.43 ± 1.44), systolic blood pressure (152.37 ± 10.24 vs. 140.33 ± 5.99), diastolic blood pressure (95.66 ± 6.34 vs. 87.33 ± 7.28), β 1-AA (33 vs. 9 cases), and AT1-AA (35 cases vs. 12 cases) were higher in the dysfunction group than in the control group (all P < 0.05). Multivariate regression analysis showed that β 1-AA (odds ratio (OR) = 1.96, 95% confidence interval (CI): 1.369-4.345) and AT1-AA (OR = 2.02, 95% CI: 1.332-6.720) were independent risk factors for cardiac diastolic dysfunction ( P < 0.05). Both autoimmune antibodies had a certain predictive value, and the combined prediction value of the two was the highest, with an area under the curve of 0.942 (95% CI: 0.881~0.985)., Conclusion: The positive rate of β 1-AA and AT1-AA in essential hypertension patients with LVDD was higher than that in the normal group. Both β 1-AA and AT1-AA could be used as early markers of LVDD in essential hypertension patients., Competing Interests: All of the authors had no separate personal, financial, commercial, or academic conflicts of interest., (Copyright © 2023 Liang Wang et al.)

Introduction: Autonomic dysreflexia (AD), a condition of critically raised blood pressure, is a severe complication of spinal cord injury. Primary (essential) hypertension may present with similar blood pressure levels to AD, though the causes, pathophysiology, presentation and treatment will differ., Case Presentation: We report a case of a 74-year-old patient with a C1 spinal injury, who developed primary (essential) hypertension during her rehabilitation phase of care, requiring extensive investigations for autonomic dysreflexia. Despite this, no underlying cause was found; essential hypertension was subsequently confirmed with 24-hour ambulatory blood pressure monitoring. Treatment with an ACE inhibitor was introduced to good effect., Discussion: Essential hypertension can affect patients with spinal injury, even though most patients with higher level injuries (particularly cervical spinal cord injuries) are expected to have low resting baseline hypotension. Relevant features of this are presented within this case; a set of criteria to differentiate essential hypertension from autonomic dysreflexia are also proposed., (© 2023.

Objective: To study the development of microalbuminuria (MAU) in essential hypertension (EHT), we investigated the association of MAU with central blood pressure (CBP), direct renin concentration (DRC), plasma aldosterone (PA), and uric acid (UA)., Method: We determined 24 h-urinary albumin excretion (24 h-UAE) in patients with EHT who were hospitalized at TEDA International Cardiovascular Hospital from June 2020 to May 2022. We defined MAU as 24 h-UAE in the range of 30 mg/24 h to 300 mg/24 h. Univariate and multivariate analyses were conducted to determine the associations of MAU with CBP, DRC, PA, and UA in EHT, considering demographic and clinical information. We also plotted receiver operating characteristic curves (ROCs) for predicting MAU using these results., Results: More than a quarter of patients (26.5%, 107/404, 95% CI: 22.2-31.1%) were diagnosed with MAU in EHT. A higher body mass index (BMI), longer duration of hypertension, and higher severity were associated with MAU. Also, nearly 10% more creatinine levels were recorded in the MAU group than in the control group (69.5 ± 18.7 µmol/L vs. 64.8 ± 12.5 µmol/L, P = 0.004). The increase was also observed for PA (15.5, 9.7-20.6 ng/dL vs. 12.3, 9.0-17.3 ng/dL, P = 0.024) and UA (419.8 ± 105.6 µmol/L vs. 375.1 ± 89.5 µmol/L, P < 0.001) in the MAU group compared to that in the control group. Several variables were associated with MAU, including central diastolic blood pressure (CDBP) (OR = 1.017, 95% CI: 1.002-1.032, P = 0.027), PA (OR = 1.043, 95% CI: 1.009-1.078, P = 0.012) and UA (OR = 1.005, 95% CI: 1.002-1.008, P < 0.001). For MAU prediction, the area under the curve (AUC) was 0.709 (95% CI: 0.662-0.753; P < 0.001) when CDBP, PA, and UA were used in combination, and the optimal probability of the cut-off value was 0.337., Conclusion: We found that CDBP, PA, and UA, used for MAU prediction, might be associated with its development during EHT., (© 2023.

We aimed to explore the association between salt sensitivity and blood pressure variability in patients with essential hypertension. A total of 730 patients with essential hypertension treated from 2016 to 2019 were subjected to salt-sensitivity risk stratification according to 24-hour ambulatory blood pressure monitoring. Their clinical data were compared among groups with different grades of salt-sensitivity risk, and the association between salt sensitivity and blood pressure variability was analysed. The influencing factors for cardiovascular events in patients with essential hypertension were analysed through multivariate regression analysis, and their predictive value was detected using receiver operating characteristic (ROC) curves. Salt sensitivity was positively correlated with night-time and 24-hour systolic standard deviation and 24-hour systolic blood pressure coefficient of variation. Age ≥ 55 years, family history of cardiovascular diseases, high risk of salt sensitivity, night-time systolic standard deviation ≥ 14 mmHg, 24-hour systolic standard deviation ≥ 20 mmHg and 24-hour systolic blood pressure coefficient of variation ≥ 13.5% were all independent risk factors for cardiovascular diseases in patients with essential hypertension ( p < 0.05). The area under the ROC curve of the prediction model was 0.837. There was a positive correlation between salt sensitivity and blood pressure variability, which has predictive value for cardiovascular events in patients with essential hypertension.

Background: Allisartan isoproxil is a selective nonpeptide angiotensin II (AT1) receptor blocker developed by China, this study aimed to assess its clinical efficacy for essential hypertension (EH)., Methods: Patients with mild-to-moderate EH, selected at 44 sites in China from September 9, 2016, to December 7, 2018, were administered 240 mg allisartan isoproxil daily for 4 weeks. Patients with controlled blood pressure (BP) continued monotherapy for 8 weeks, others were randomly assigned (1:1) to A + D group (allisartan isoproxil 240 mg + indapamide 1.5 mg) or A + C group (allisartan isoproxil + amlodipine besylate 5 mg) for 8 weeks. BP were measured at week 4, 8 and 12., Results: 2,126 patients were included in the analysis. After 12 weeks of treatment, systolic blood pressure (SBP) and diastolic blood pressure (DBP) decreased by 19.24 ± 12.02 and 10.63 ± 8.89 mm Hg, respectively, and the overall BP control rate was 78.56%. The sitting blood pressures (SBP/DBP) decreased by 19.12 ± 11.71/10.84 ± 8.73 mm Hg in patients with 12 weeks allisartan isoproxil monotherapy (both P < 0.0001). The BP reductions and control rates were comparable between A + D and A + C groups. 48 patients with monotherapy-controlled BP underwent ambulatory BP monitoring, with a mean decrease in ambulatory BP of 10.04 ± 10.87/5.50 ± 8.07 mm Hg after 12 weeks of treatment, and consistent reductions between day and night. SBP and DBP had trough-to-peak ratios of 64.64% and 62.63% and smoothness indices of 3.82 and 2.92, respectively., Conclusions: An allisartan isoproxil-based antihypertensive regimen can effectively control BP in patients with mild-to-moderate EH., Project Registration No: CTR20160138 (Registration and Information Disclosure Platform for China Drug Clinical Studies, http://www.chinadrugtrials.org.cn/index.html)., (© The Author(s) 2023.

This study aimed to evaluate the efficacy of single-pill combination (SPC) antihypertensive drugs in patients with uncontrolled essential hypertension. Through Searching Pubmed, EMBASE, the Cochrane Library, and Web of Science collected only randomized controlled trials on the efficacy of single-pill combination antihypertensive drugs in people with uncontrolled essential hypertension. The search period is from the establishment of the database to July 2022. The methodological quality of the included studies was assessed using the Cochrane Risk of Bias Assessment, and statistical analyses were performed using Review Manage 5.3 and Stata 15.1 software. This review ultimately included 32 references involving 16 273 patients with uncontrolled essential hypertension. The results of the network meta-analysis showed that a total of 11 single-pill combination antihypertensive drugs were included, namely: Amlodipine/valsartan, Telmisartan/amlodipine, Losartan/HCTZ, Candesartan/HCTZ, Amlodipine/benazepril, Telmisartan/HCTZ, Valsartan/HCTZ, Irbesartan/amlodipine, Amlodipine/losartan, Irbesartan/HCTZ, and Perindopril/amlodipine. According to SUCRA, Irbesartan/amlodipine may rank first in reducing systolic blood pressure (SUCRA: 92.2%); Amlodipine/losartan may rank first in reducing diastolic blood pressure (SUCRA: 95.1%); Telmisartan/amlodipine may rank first in blood pressure control rates (SUCRA: 83.5%); Amlodipine/losartan probably ranks first in diastolic response rate (SUCRA: 84.5%). Based on Ranking Plot of the Network, we can conclude that single-pill combination antihypertensive drugs are superior to monotherapy, and ARB/CCB combination has better advantages than other SPC in terms of systolic blood pressure, diastolic blood pressure, blood pressure control rate, and diastolic response rate. However, due to the small number of some drug studies, the lack of relevant studies has led to not being included in this study, which may impact the results, and readers should interpret the results with caution., (© 2023 The Authors.

Objectives: This study aimed to evaluate the relationships between serum levels of 25-hydroxyvitamin D (25(OH)D) and short-term blood pressure variability (BPV) in newly diagnosed hypertensive patients., Methods: One hundred newly diagnosed patients with stage one essential hypertension were included and divided into two groups, the deficient and non-deficient groups, according to their 25(OH)D level. The blood pressure was recorded automatically by a portable ambulatory blood pressure monitor for 24 h., Results: In the present study, there was no significant relationship between vitamin D levels and short-term BPV or other parameters derived from ambulatory blood pressure monitoring (ABPM) (P > 0.05). Age (r = 0.260, P = 0.009), serum phosphorus (r = 0.271, P = 0.007), and cholesterol levels (r = 0.310, P = 0.011) were positively correlated with 25(OH)D levels, while glomerular filtration rate (r = -0.232, P = 0.021) negatively correlated with vitamin D levels. There was no crude or adjusted relationship between the levels of 25(OH)D and any parameters of ABPM in multiple linear regression analysis., Conclusion: Although the relationship between vitamin D levels and cardiovascular diseases has been confirmed, vitamin D deficiency does not cause an increase in cardiovascular risk by influencing the short-term BPV or other parameters derived from ABPM., (Copyright © 2023 Wolters Kluwer Health, Inc.

Mounting evidence has confirmed that essential hypertension (EH) is closely related to low-grade inflammation, but there is still a lack of in-depth understanding of the state of immune cells in the circulating blood of patients with EH. We analyzed whether hypertensive peripheral blood immune cell balance was destroyed. The peripheral blood mononuclear cells (PBMCs) of all subjects were analyzed using time-of-flight cytometry (CyTOF) based on 42 kinds of metal-binding antibodies. CD45 + cells were categorized into 32 kinds of subsets. Compared with the health control (HC) group, the percentage of total dendritic cells, two kinds of myeloid dendritic cell subsets, one intermediate/nonclassical monocyte subset and one CD4 + central memory T cell subset in the EH group, was significantly higher; the percentage of low-density neutrophils, four kinds of classical monocyte subsets, one CD14 low CD16 - monocyte subset, one naive CD4 + and one naive CD8 + T cell subsets, one CD4 + effector and one CD4 + central memory T cell subsets, one CD8 + effector memory T cell subset, and one terminally differentiated γδ T cell subset, decreased significantly in EH. What is more, the expression of many important antigens was enhanced in CD45 + immune cells, granulocytes, and B cells in patients with EH. In conclusion, the altered number and antigen expression of immune cells reflect the imbalanced immune state of the peripheral blood in patients with EH., Competing Interests: The authors declare that there is no conflict of interest regarding the publication of this paper., (Copyright © 2023 Rui Yang et al.)

Background Targeted treatment with mineralocorticoid receptor antagonists (MRAs) or adrenalectomy in patients with primary aldosteronism (PA) causes a decline in estimated glomerular filtration rate; however, the associated simultaneous changes in biomarkers of kidney tubule health still remain unclear. Methods and Results We matched 104 patients with newly diagnosed unilateral PA who underwent adrenalectomy with 104 patients with unilateral PA who were treated with MRAs, 104 patients with bilateral PA treated with MRAs, and 104 patients with essential hypertension who served as controls. Functional biomarkers were measured before the targeted treatment and 1 year after treatment, including serum markers of kidney function (cystatin C, creatinine), urinary markers of proximal renal tubular damage (L-FABP [liver-type fatty-acid binding protein], KIM-1 [kidney injury molecule-1]), serum markers of kidney tubular reserve and mineral metabolism (intact parathyroid hormone), and proteinuria. Compared with the patients with essential hypertension, the patients with PA had higher pretreatment serum intact parathyroid hormone and urinary creatinine-corrected parameters, including L-FABP, KIM-1, and albumin. The patients with essential hypertension and with PA had similar cystatin C levels. After treatment with MRAs or adrenalectomy of unilateral PA and MRAs of bilateral PA, the patients with PA had increased serum cystatin C and decreased urinary L-FABP/creatinine, KIM-1/creatinine, creatinine-based estimated glomerular filtration rate, intact parathyroid hormone, and proteinuria (all P <0.05). In multivariable regression models, a higher urinary L-FABP/creatinine ratio and older age were significantly correlated with the occurrence of kidney failure (estimated glomerular filtration rate dip ≥30%) in the patients with PA after targeted treatment. Conclusions Compared with the matched patients with essential hypertension, the incident patients with PA at diagnosis had higher levels of several biomarkers, including markers of kidney damage, tubular reserve/mineral metabolism, and proteinuria. Functional kidney failure in the patients with PA after treatment could be predicted by a higher baseline urinary L-FABP/creatinine ratio and older age. After targeted treatments in the patients with bilateral or unilateral PA, these biomarkers of kidney tubule health were restored, but creatinine-based estimated glomerular filtration rate declined, which may therefore reflect hemodynamic changes rather than intrinsic damage to kidney tubular cells.

Objective: Previous studies have shown that serum bilirubin (BIL) is significantly decreased, and serum creatinine (Cr) level is increased in patients with essential hypertension (EH). In this paper, the ratio of serum Cr to BIL was measured to explore whether the ratio was associated with EH risk., Patients and Methods: 80 EH cases were selected as the observation group. 44 cases with normal blood pressure were selected as the control group. Serum Cr and BIL levels were detected, and the ratio values were calculated., Results: Compared with the control group, the Cr to total bilirubin (TBIL) ratio (Cr/TBIL, CTR), Cr to direct bilirubin (DBIL) ratio (Cr/DBIL, CDR) and Cr to indirect bilirubin (IBIL) ratio (Cr/IBIL, CIR) in the EH group were significantly increased (p<0.05). Spearman correlation analysis showed that EH risk was positively correlated with CTR and CIR, while it was negatively correlated with serum BIL (p<0.05). The area under the ROC curve of CTR, CDR and CIR in diagnosing EH were 0.719 (95% CI: 0.631-0.796) (p<0.001), 0.700 (95% CI: 0.611-0.779) (p<0.001) and 0.716 (95% CI: 0.628-0.793) (p<0.001), respectively. Logistic regression analysis showed that CTR, CDR and CIR were independent risk factors for EH (CTR OR: 1.28, 95% CI: 1.11-1.48, p=0.0008), (CDR OR: 1.03, 95% CI: 1.003-1.067, p=0.032), (CIR OR: 1.17, 95% CI: 1.07-1.29, p=0.001)., Conclusions: CTR and CIR are positively correlated with the incidence of EH. With the increase of blood pressure, CTR and CIR increase. CTR and CIR are independent risk factors for the incidence of EH.

Background: AT1 receptor gene (AGTR1) is related to essential hypertension (EH), and left ventricular hypertrophy (LVH) and arterial stiffness are common complications of EH. This study aimed to explore the association between AGTR1 genotype and LVH and arterial stiffness in EH patients., Methods: A total of 179 EH patients were recruited in this study. Oral exfoliated cells were collected from each patient, and the genetic polymorphism of AGTR1(rs4524238) was assessed using a gene sequencing platform. The outcomes were LVH and arterial stiffness., Results: Among 179 patients, 114 were with AGTR1 genotype of GG (57 males, aged 59.54 ± 13.49 years) and 65 were with AGTR1 genotype of GA or AA (36 males, aged 61.28 ± 12.79 years). Patients with AGTR1 genotype of GG were more likely to have LVH (47 [41.23%] vs. 14 [21.54%], P = 0.006) and arterial stiffness (30 [26.32%] vs. 8 [12.31%], P = 0.036). The AGTR1 polymorphism frequency was in accordance with Hardy-Weinberg equilibrium (P = 0.291). The multivariate logistic regression showed that AGTR1 genotype of GA or AA was independently associated with lower risk of LVH (OR = 0.344, 95%CI 160~0.696, P = 0.003) and arterial stiffness (OR = 0.371, 95%CI 0.155~0.885, P = 0.025) after adjusting for gender, age, and diabetes., Conclusion: EH patients with the AGTR1 genotype of GA or AA were at lower risk for LVH and arterial stiffness than those with the GG genotype., (© 2022.

Aim: The systemic immune-inflammation index (SII) has been reported to have a prognostic ability in various cardiovascular diseases and tumours. In this study, we aimed to investigate whether there was an association between SII and gender and age in newly diagnosed, treatment-naïve, hypertensive patients., Methods: A total of 153 participants, of whom 93 were men and 60 were women, were included in this retrospective study. Retrospective evaluation of the patients was performed using electronic medical records. The SII was calculated according to the following formula at admission: SII = platelet × neutrophil/lymphocyte counts., Results: The SII was significantly higher in women compared to men (546.31 vs 385, respectively, p = 0.003) and was positively correlated with age. The receiver operating characteristic curve shows the SII cut-off value predicting new-onset essential hypertension with a sensitivity of 67.6% and a specificity of 67.2% in women., Conclusions: According to these results, using the SII in cardiovascular diseases may be recommended to increase survival rate in hypertensive women.

Objective: This study aims to explore the diagnostic value of the deepest S wave (S D ) in elderly patients with essential hypertension and left ventricular hypertrophy (LVH)., Methods: A retrospective study was conducted in elderly patients with essential hypertension from October 2020 to December 2021. The 12-lead electrocardiogram (ECG) examination was carried out at the time of admission. Echocardiography was performed to estimate left ventricular mass (LVM) and the left ventricular muscle mass index (LVMI) was adjusted by the body surface area (BSA). The Receiver Operating Characteristic (ROC) curve for diagnosing hypertension with LVH was drawn, the cut-off value was determined according to the Youden index, and the area under the curve (AUC) was calculated. The diagnostic values of S D , S D +S v4 , r avl +S v3 , and S v1 +R v5 were compared., Results: The results of S D , S D +S v4 , R avL +S v3 , and S v1 +R v5 in the Study group were 2.03 (1.56-2.57) mV, 3.09 (2.38-3.98) mV, 2.19 (1.46-2.78) mV, and 3.38 (2.67-4.19) mV respectively, which were all higher than those in the Control group [0.93 (0.68-1.23) mV, 1.37 (1.32-2.18) mV, 1.03 (0.68-1.46) mV, and 2.28 (1.67-2.67) mV], P <0.001. Compared with the ROC curved by S D +S v4 , R avL +S v3 , and S v1 +R v5 , the AUC of the ROC curved by S D was [0.887, 95% CI (0.837-0.927)], and the cut-off value was 1.298 with the Sensitivity = 86.03 and Specificity = 86.59 in diagnosing essential hypertension with LVH. In female patients, the AUC of the ROC curved by S D was [0.891, 95% CI (0.841-0.934)], and the cut-off value was 1.304 with the Sensitivity of 89.32% and Specificity of 88.67%, which were all higher than those in male patients [AUC = 0.887, 95% CI (0.828-0.943); cut-off value = 1.288; Sensitivity = 82.12%, and Specificity = 84.22%]., Conclusion: ECG can effectively diagnose elderly patients with essential hypertension and LVH and the diagnostic value of S D and S D +S v4 are higher than the current Cornell criteria and Sokolow-Lyon criteria., Competing Interests: The authors report no conflicts of interest in this work., (© 2022 Ji et al.)

Background: Previous studies reported that there was right ventricular (RV) systolic dysfunction in patients with hypertension. The aim of this study was to evaluate the impact of type 2 diabetes mellitus (T2DM) on RV systolic dysfunction and interventricular interactions using cardiac magnetic resonance feature tracking (CMR-FT) in patients with essential hypertension., Methods and Methods: Eighty-five hypertensive patients without T2DM [HTN(T2DM -)], 58 patients with T2DM [HTN(T2DM +)] and 49 normal controls were included in this study. The biventricular global radial, circumferential and longitudinal peak strains (GRS, GCS, GLS, respectively) and RV regional strains at the basal-, mid- and apical-cavity, were calculated with CMR-FT and compared among controls and different patient groups. Backward stepwise multivariable linear regression analyses were used to determine the effects of T2DM and left ventricular (LV) strains on RV strains., Results: The biventricular GLS and RV apical longitudinal strain deteriorated significantly from controls, through HTN(T2DM-), to HTN(T2DM +) groups. RV middle longitudinal strain in patient groups were significantly reduced, and LV GRS and GCS and RV basal longitudinal strain were decreased in HTN(T2DM +) but preserved in HTN(T2DM-) group. Multivariable regression analyses adjusted for covariates demonstrated that T2DM was independently associated with LV strains (LV GRS: β = - 4.278, p = 0.004, model R 2  = 0.285; GCS: β = 1.498, p = 0.006, model R 2  = 0.363; GLS: β = 1.133, p = 0.007, model R 2  = 0.372) and RV GLS (β = 1.454, p = 0.003, model R 2  = 0.142) in hypertension. When T2DM and LV GLS were included in the multiple regression analysis, both T2DM and LV GLS (β = 0.977 and 0.362, p = 0.039 and < 0.001, model R 2  = 0.224) were independently associated with RV GLS., Conclusions: T2DM exacerbates RV systolic dysfunction in patients with hypertension, which may be associated with superimposed LV dysfunction by coexisting T2DM and suggests adverse interventricular interactions., (© 2022.

Background: Blood pressure (BP) exhibits seasonal variations, with peaks reported in winter. However, the association between seasonal variations and blood pressure variability in patients with new-onset essential hypertension is not fully understood. This study evaluated the potential association of seasonal variations with new-onset essential hypertension., Methods: This retrospective observational study recruited a total of 440 consecutive patients with new-onset essential hypertension who underwent 24-h ambulatory electrocardiograph (ECG) and BP measurement at our department between January 2019 and December 2019. Demographic and baseline clinical data including BP variability, heart rate variability, and blood tests were retrieved. Multivariate linear regression analysis was performed to identify factors independently associated with mean BP and BP variability., Results: Among the 440 patients recruited, 93 cases were admitted in spring, 72 in summer, 151 in autumn, and 124 in winter. Univariate analysis revealed that systolic BP (SBP), diastolic BP (DBP), high-sensitivity C-reactive protein, SBP drop rate, DBP drop rate, 24-h standard deviation of SBP, 24-h standard deviation of DBP, 24-h SBP coefficient of variation, and 24-h DBP coefficient of variation were associated with patients admitted in winter (P < 0.05 for all). Multivariate linear regression analysis showed that winter was the influencing factor of 24-h standard deviation of SBP (B = 1.851, t = 3.719, P < 0.001), 24-h standard deviation of DBP (B = 1.176, t = 2.917, P = 0.004), 24-h SBP coefficient of variation (B = 0.015, t = 3.670, P < 0.001), and 24-h DBP coefficient of variation (B = 0.016, t = 2.849, P = 0.005) in hypertensive patients., Conclusions: Seasonal variations are closely associated with BP variability in patients with new-onset essential hypertension. Our study provides insight into the underlying pathogenesis of new-onset essential hypertension., (© 2022. The Author(s).)

Researchers have shown that 25-hydroxyvitamin D (25[OH] D), a kind of active vitamin D in the human body, plays a role in cardiovascular disease (CVD). Low serum 25(OH) D levels have been found to be associated with elevated blood pressure (BP) in adults. However, measurement of 25(OH) D in hypertensive children has not been documented. The aim of this study was to investigate the relationship between 25(OH) D and target organ damage (TOD) in children with essential hypertension. We recruited a total of 346 children with essential hypertension and analyzed the correlation between serum 25(OH) D and TOD. Serum 25(OH) D concentration was significantly lower in the TOD than in the no-TOD group (t = 2.416, P = 0.016), as well as significantly lower in the two-organ damage than in the single-organ damage group (t = 3.140, P = 0.002). Pearson's correlation coefficient (PCC) indicated that serum 25(OH) D levels were negatively correlated with left ventricular mass index (LVMI; r = -0.110, P = 0.041) and albuminuria (r = -0.120, P = 0.026). Linear- regression analysis showed that 25(OH) D was a risk factor for left ventricular hypertrophy (LVH; β ± s.e. =-0.074 ± 0.036; 95% confidence interval [CI], - 0.145 to -0.003; P < 0.001) and renal damage (β ± s.e.= -0.018 ± 0.008; 95% CI, - 0.035 to -0.002; P = 0.004). In total, our data revealed that serum 25(OH) D was independently associated with hypertensive cardiac and renal damage, meaning that it was a risk factor for LVH and albuminuria in childhood hypertension., (© 2021.

Flaxseed oil is an excellent source of alpha-linolenic acid ALA known for its antihypertensive action. Flaxseed oil is unstable and its dose is not achievable in our conventional diet hence blending of natural flaxseed oil with palm oil, containing high flavonoids may be a better strategy, to stabilize the blend and provide proper balance of essential fatty acids and potential antioxidant effects. Aim of this study was to access the effect of blended flaxseed oil on 24 h 7-day circadian variations of blood pressure in subjects with essential hypertension. Assessment of CHAT (circadian hyper amplitude tension) using ABPM is the best marker for cardiovascular function. We registered 50 subjects with CAD (Group 1) and 50 subjects with Essential hypertension HT (Group 2) and 52 control subjects with CAD/Hypertension. Group 1 and 2 participant was supplemented with blended flaxseed oil (BFO) (30 ml/day) for the period of 24 weeks, while control group administered available oils sunflower in identical containers, for a follow-up period of 24 weeks. Twenty four hour seven days continuous ambulatory blood pressure monitoring was done initially and after six months of BFO supplementation. There were significant changes noted in lipid profile along with Ambulatory blood pressure parameters like MESOR, ACROPHASE, Hyperbaric Indexes, and CHAT. Circadian hyper amplitude tension (CHAT) incidence decreased after BFO supplementation. Study results suggest that blended flaxseed oil administration can be a potent natural vegetarian antihypertensive supplement which helps in synchronization of cardiac rhythms, and can be used as a preventive treatment of hypertension and as effective vegetarian source of maintaining Omega 3 and omega 6 ratios of essential fatty acids in the body., (© 2021.

Background: Hypertension is one of the most challenging public health problems worldwide. Previous studies suggested that the Songling Xuemaikang capsule (SXC)-a Chinese herbal formula-was effective for essential hypertension. However, the efficacy of SXC monotherapy for hypertension remains unclear. We aimed to compare the blood pressure (BP)-lowering efficacy and safety of SXC versus losartan in patients with essential hypertension., Methods: In this multicenter, randomized, double-blind, noninferiority trial in China, patients 18 to 65 years of age with mild essential hypertension were randomly allocated to receive either SXC or losartan for 8 weeks. The primary outcome was the change in sitting diastolic BP from baseline to 8 weeks, with a predefined noninferiority margin of -2.5 mm Hg., Results: Of the 755 patients who entered a 2-week run-in period, 628 patients (327 women and 301 men; mean [SD] age, 52.6 [9.2] years) were randomly assigned to the SXC (n=314) or losartan (n=314) group. The primary analysis based on the intention-to-treat principle showed that the change in diastolic BP from baseline to 8 weeks was similar between the SXC and losartan groups (-7.9 [8.0] versus -8.1 [7.9]). The lower boundary of 95% CI (mean difference, -0.24 [95% CI, -1.51 to 1.03]) was above the margin of -2.5 mm Hg, showing noninferiority. Results were consistent with per-protocol analysis. SXC produced greater improvements in total hypertension symptom score (-5.7 [4.2] versus -5.0 [4.0]; P =0.020) and total cholesterol (-0.1 [1.0] versus 0.1 [1.2]; P =0.025). There were no differences between groups in the other BP and patient-reported outcomes. Incidence and severity of adverse events were similar between groups., Conclusions: SXC was well tolerated and demonstrated noninferior to losartan in BP lowering in patients with mild hypertension. SXC might be an alternative for mild hypertension, particularly for patients with a preference for natural medicine., Registration: URL: www.chictr.org.cn; Unique identifier: ChiCTR-IPR-16008108.

Background: Essential hypertension (EH) is a common and multifactorial disorder that is likely to be influenced by multiple genes. The methylenetetrahydrofolate reductase ( MTHFR ) gene rs1801133 and rs1801131 polymorphisms influence MTHFR enzyme activity and plasma homocysteine concentration. In addition, variations in MTHFR functions likely play roles in the etiology of EH. Thus far, a large number of studies investigating the associations between the MTHFR polymorphisms and EH have provided controversial or inconclusive results. To better assess the purported relationship, we performed a comprehensive analysis of 52 published studies. Objective and Methods . Eligible studies were identified by searching the PubMed, Wanfang, and China National Knowledge Infrastructure (CNKI) databases. Odds ratios (ORs) with 95% confidence intervals (CIs) were estimated to assess the potential association between the MTHFR rs1801133 polymorphism and EH., Results: Overall, 10712 patients and 11916 controls were involved; we observed significantly increased association between the MTHFR rs1801133 polymorphism and EH risk (such as T vs. C: OR = 1.38, 95% CI = 1.25 - 1.54, P ≤ 0.001), with similar results evident within race subgroups (such as Asian: T vs. C: OR = 1.47, 95% CI = 1.30 - 1.67, P ≤ 0.001; compared to Chinese: T vs. C: OR = 1.54, 95% CI = 1.33 - 1.79, P ≤ 0.001). Similar associations were also found in subgroups defined by the source of controls and genotype methods. To our regret, based on the limited studies, no association was detected for rs1801131 polymorphism., Conclusions: Our study provides evidence that the MTHFR rs1801133 null genotype may increase EH risk. Future studies with larger sample sizes are warranted to evaluate this association in more detail., Competing Interests: The authors declare no conflict of interest., (Copyright © 2022 Yingchao Fan et al.)

Background: The effect of comorbid hypertension and type 2 diabetes mellitus (T2DM) on coronary artery plaques examined by coronary computed tomography angiography (CCTA) is not fully understood. We aimed to comprehensively assess whether comorbid hypertension and T2DM influence coronary artery plaques using CCTA., Materials and Methods: A total of 1100 T2DM patients, namely, 277 normotensive [T2DM(HTN-)] and 823 hypertensive [T2DM(HTN +)] individuals, and 1048 normotensive patients without T2DM (control group) who had coronary plaques detected on CCTA were retrospectively enrolled. Plaque type, coronary stenosis, diseased vessels, the segment involvement score (SIS) and the segment stenosis score (SSS) based on CCTA data were evaluated and compared among the groups., Results: Compared with patients in the control group, the patients in the T2DM(HTN-) and T2DM(HTN +) groups had more partially calcified plaques, noncalcified plaques, segments with obstructive stenosis, and diseased vessels, and a higher SIS and SSS (all P values < 0.001). Compared with the control group, T2DM(HTN +) patients had increased odds of having any calcified and any noncalcified plaque [odds ratio (OR) = 1.669 and 1.278, respectively; both P values < 0.001]; both the T2DM(HTN-) and T2DM(HTN +) groups had increased odds of having any partially calcified plaque (OR = 1.514 and 2.323; P = 0.005 and P < 0.001, respectively), obstructive coronary artery disease (CAD) (OR = 1.629 and 1.992; P = 0.001 and P < 0.001, respectively), multivessel disease (OR = 1.892 and 3.372; both P-values < 0.001), an SIS > 3 (OR = 2.233 and 3.769; both P values < 0.001) and an SSS > 5 (OR = 2.057 and 3.580; both P values < 0.001). Compared to T2DM(HTN-) patients, T2DM(HTN +) patients had an increased risk of any partially calcified plaque (OR = 1.561; P = 0.005), multivessel disease (OR = 1.867; P < 0.001), an SIS > 3 (OR = 1.647; P = 0.001) and an SSS > 5 (OR = 1.625; P = 0.001)., Conclusion: T2DM is related to the presence of partially calcified plaques, obstructive CAD, and more extensive coronary artery plaques. Comorbid hypertension and diabetes further increase the risk of partially calcified plaques, and more extensive coronary artery plaques., (© 2022. The Author(s).)

Whether arteriosclerosis can influence the hypertension control remains incompletely understood. We hypothesized that higher arteriosclerosis may be associated with uncontrolled hypertension. Arteriosclerosis was assessed by carotid femoral artery pulse wave velocity (CF-PWV) and uncontrolled hypertension (systolic blood pressure [BP] ≥130 mm Hg or diastolic BP ≥80 mm Hg). The multivariable-adjusted logistic regression was used for analysis. A total of 1,428 patients with essential hypertension (mean age 68 years, 49.6% male) were enrolled into the study from 2010 to 2017. The BP was uncontrolled in 50.7% of the participants and the mean level of CF-PWV was 12.3 m/s. All the cardiovascular risk factors were worse and CF-PWV was higher in patients with uncontrolled hypertension (all p < 0.05). Multivariable-adjusted logistic regression analysis showed that CF-PWV as a continuous variable (odd ratio [OR] 1.093, 95% confidence interval [CI] 1.046-1.142) was independently associated with uncontrolled hypertension, after male (OR 1.511) and total cholesterol (OR 1.167), followed by body mass index (OR 1.092), fasting plasma glucose (OR 1.075), and creatinine (OR 1.010) (all p < 0.05). As a binary variable, CF-PWV >12 m/s was also independently associated with uncontrolled hypertension (OR 1.690, 95% CI 1.320-2.164, p < 0.05). Arteriosclerosis is independently associated with uncontrolled BP in patients with hypertension., (© 2022 S. Karger AG, Basel.)

Determination of plasma aldosterone concentrations (PAC) and plasma active renin concentrations (ARC) is essential for the diagnosis of primary aldosteronism (PA). In Japan, although PAC and ARC are measured by radioimmunoassay and immunoradiometric assay, respectively, non-radioisotopic methods with better detection sensitivity, measurement accuracy, and technical simplicity are needed. We developed two-site sandwich chemiluminescent enzyme immunoassays (CLEIAs) to measure both PAC and ARC using monoclonal antibodies immobilized onto ferrite particles. The results of both assays are obtained simultaneously from a single plasma sample within 30 min using a fully automated system. The novel CLEIAs were validated using plasma samples from patients with PA (n = 52) and essential hypertension (n = 23). The PAC determined by the CLEIA was significantly correlated with that measured by liquid chromatography/mass spectrometry or conventional radioimmunoassay. The ARC determined by the CLEIA was significantly correlated with that measured by immunoradiometric assay. The limits of detection of the CLEIAs for PAC and ARC were 0.1 ng/dl and 0.04 pg/ml, respectively, which were better than those of conventional methods (PAC: 2.5 ng/dl; ARC: 5 pg/ml). The PAC and PAC/ARC ratio (ARR) were significantly higher, and the ARC significantly lower, in patients with PA than in those with essential hypertension. An ARR cut-off of 1.31 ng/dl per pg/ml showed a sensitivity of 96.2% and specificity of 78.3% for PA screening. The newly developed CLEIAs for measuring PAC and ARC could provide a clinically powerful alternative to conventional methods used for hypertension screening in clinical practice., (© 2021.

Objective: Long-term outcomes (especially mortality and/or major cardiovascular events (MACE)) of the unilateral primary aldosteronism (uPA) patients who underwent medical or surgery-targeted treatment, relative to those with essential hypertension (EH), have been scarcely reported., Design and Settings: Using the prospectively designed observational Taiwan Primary Aldosteronism Investigation cohort, we identified 858 uPA cases among 1220 primary aldosteronism patients and another 1210 EH controls., Exposures: Operated uPA patients were grouped via their 1-year post-therapy statuses., Results: Primary Aldosteronism Surgical Outcome clinical complete success (hypertension remission) was achieved in 272 (49.9%) of 545 surgically treated uPA patients. After follow-up for 6.3 ± 4.0 years, both hypertension-remissive (hazard ratio (HR): 0.54; P < 0.001) and not-cured (HR: 0.61; P < 0.001) uPA patients showed a lower risk of all-cause mortality than that of EH controls; whereas the not-cured group had a higher risk of incident MACE (sub-hazard ratio (sHR), 1.41; P = 0.037) but similar atrial fibrillation (Af) and congestive heart failure (CHF). Mineralocorticoid receptor antagonist (MRA)-treated uPA patients had higher risks of MACE (sHR: 1.38; P = 0.033), Af (sHR:1.62, P = 0.049), and CHF (sHR: 1.44; P = 0.048) than those of EH controls, with mortality as a competing risk. Using inverse probability of treatment-weighted matching and counting adrenalectomy as a time-varying factor, treatment with adrenalectomy was associated with lower risks of all-cause mortality (HR: 0.57; P = 0.035), MACE (HR: 0.67; P = 0.037), and CHF (HR: 0.49; P = 0.005) compared to those of MRA therapy., Conclusions: Adrenalectomy, independent of post-surgical hypertension remission, was associated with lower all-cause mortality of uPA patients, compared to that of EH patients. We further documented a more beneficial effect of adrenalectomy over MRA treatment on long-term mortality, MACE, and CHF in uPA patients.

Hypertension is a complex disease which is mainly influenced by genetic factors. Recently, genome-wide association study (GWAS) found three novel endothelial dysfunction-related sites: Vascular endothelial growth factor A ( VEGFA ) rs9472135, Faciogenital dysplasia 5 ( FGD5 ) rs11128722, Zinc Finger C3HC-type Containing 1 ( ZC3HC1 ) rs11556924. Endothelial dysfunction is one of the early events in pathophysiology of essential hypertension. To investigate the association of endothelial dysfunction-related genes with essential hypertension, we conducted a case-control study of 431 patients with hypertension and 345 controls. The polymorphisms were detected using Taqman Probe. The alleles and genotypes of ZC3HC1 rs11556924 and VEGFA rs9472135 were not statistically different between the two groups, while the allele of FGD5 rs11128722 was different [ P = 0.045, OR = 1.265, 95% CI = (1.009-1.586)], especially in the male [ P = 0.035, OR = 1.496, 95% CI = (1.037-2.158)]. Analyzing the different of genotype distribution of 3 SNPs in the two groups under different genetic models, the genotypes of FGD5 rs11128722 showed difference in male under dominant model [ P = 0.049, OR = 1.610, 95% CI = (1.018-2.544)]. The polymorphism of FGD5 rs11128722 had a significant difference in Body Mass Index (BMI) among different genotypes; In the additive genetic model, BMI of GA genotype was higher than that of GG ( P = 0.038); GA + AA was higher than GG in the dominant genetic model ( P = 0.011). In our study, we found that the polymorphisms of VEGFA rs9472135 and ZC3HC1 rs11556924 may not significantly associated with the risk of essential hypertension, and FGD5 rs11128722 may increase the risk of it, especially in elderly men., Competing Interests: The authors declare no conflict of interest., (© 2021 The Author(s).

Objective: Although aortic dissection occurs predominantly in men, its association with androgens is unknown. The aim of this study was to evaluate the androgen levels in Chinese male patients with uncomplicated, acute type B aortic dissection., Study Design: Cross-sectional study., Materials and Methods: A total of 192 age-matched male patients with uncomplicated, acute type B aortic dissection or essential hypertension were recruited between 2016 and 2018. The demographic and clinical data were analyzed., Results: Male patients with uncomplicated, acute type B aortic dissection had lower serum total testosterone and free testosterone than male patients with essential hypertension (7.6 ± 3.7 nmol/L vs. 10.9 ± 3.8 nmol/L, P < 0.001; 36.0 ± 19.8 pmol/L vs. 56.4 ± 19.2 pmol/L, P < 0.001). Lower free testosterone level was significantly associated with uncomplicated, acute type B aortic dissection (univariate odds ratio 0.948, P < 0.001; multivariate odds ratio = 0.966, P = 0.002). No statistical difference was observed for free testosterone between younger patient groups (aged < 51 years; aged 51-60 years) and older patient groups (aged 61-70 years; aged >70 years) with uncomplicated, acute type B aortic dissection (33.7 ± 19.8 pmol/L vs. 38.5 ± 19.8 pmol/L, P = 0.239)., Conclusions: Lower free testosterone was independently associated with uncomplicated, acute type B aortic dissection in the Chinese male population with hypertension. Additional studies are needed to clarify whether earlier onset in Chinese patients with aortic dissection is associated with androgen deficiency., (Copyright © 2021 Elsevier Inc.

Introduction: Women with preeclampsia are more likely to have abnormal echocardiographic parameters at the time of diagnosis and are more likely to have hypertension and other cardiovascular diseases (CVD) later in life. Screening for future CVD in preeclamptic women would assist in appropriately risk stratifying and identifying high risk women for preventive management; however, the timing of screening and the screening factors are unknown., Objective: The objectives of this project are to 1) assess incidence of essential hypertension 4 years after pregnancy in preeclampsia with severe features (PEC) 2) identify predictive echocardiographic variables at the time of PEC diagnosis and 3) assess the rate of echocardiographic abnormalities 4 years after developing PEC., Study Design: This is a prospective longitudinal study observing the incidence of essential hypertension in women within 4 years of a pregnancy complicated by PEC. We further looked at echocardiographic variables at the time of PEC diagnosis and at 4 years after PEC pregnancy in women with and without subsequent incident essential hypertension. The primary outcome measure is the incidence of essential hypertension within 4 years of PEC pregnancy, defined as a systolic blood pressure ≥ 130 mmHg or a diastolic blood pressure ≥ 80 mmHg. Secondary imaging outcomes include the persistence of abnormal echocardiographic parameters. Clinical secondary outcomes are new diagnoses of severe CVD, including coronary artery disease, stroke, arrhythmia, heart failure, or inpatient hospital admission for CVD., Results: Of the 33 enrolled women with PEC, 48% (16/33) developed incident essential hypertension within 4 years of delivery. These women had thicker left ventricular posterior walls on their initial antenatal echocardiogram when compared to the 52% (17/33) who did not develop hypertension (1.0 cm [0.9-1.1 cm] vs 0.9 cm [0.7-0.9 cm]. p < 0.016). However, these abnormal echocardiographic variables resolved in the 16 women who underwent 4-year follow-up echocardiography., Conclusion: Women who develop PEC have a high incidence of essential hypertension within 4 years of delivery. The group who develops essential hypertension are more likely to have evidence of adverse cardiac remodeling at the time of PEC diagnosis; however, neither group have cardiac echocardiographic abnormalities 4 years postpartum. Because this is a small study, larger long-term cohort studies are needed to confirm these echocardiographic and clinical findings., (Copyright © 2021 International Society for the Study of Hypertension in Pregnancy.

Background and Aims: Insufficient dietary fiber (DF) intake is associated with increased blood pressure (BP) and the mode of action is unclear. The intake of DF supplements by participants in previous interventional studies was still far below the amount recommended by the World Health Organization. Therefore, this study aims to explore the effect of supplementing relatively sufficient DF on BP and gut microbiota in patients with essential hypertension (HTN)., Methods and Results: Fifty participants who met the inclusion criteria were randomly divided into the DF group (n = 25) and control group (n = 25). All the participants received education on regular dietary guidance for HTN. In addition to dietary guidance, one bag of oat bran (30 g/d) supplement (containing DF 8.9 g) was delivered to the DF group. The office BP (oBP), 24 h ambulatory blood pressure, and gut microbiota were measured at baseline and third month. After intervention, the office systolic blood pressure (oSBP; P < 0.001) and office diastolic blood pressure (oDBP; P < 0.028) in the DF group were lower than those in the control group. Similarly, the changes in 24hmaxSBP (P = 0.002), 24hmaxDBP (P = 0.001), 24haveSBP (P < 0.007), and 24haveDBP (P = 0.008) were greater in the DF group than in the control group. The use of antihypertensive drugs in the DF group was significantly reduced (P = 0.021). The β diversity, including Jaccard (P = 0.008) and Bray-Curtis distance (P = 0.004), showed significant differences (P < 0.05) between two groups by the third month. The changes of Bifidobacterium (P = 0.019) and Spirillum (P = 0.006) in the DF group were significant., Conclusions: Increased DF (oat bran) supplement improved BP, reduced the amount of antihypertensive drugs, and modulated the gut microbiota., Trial Registration Number: ChiCTR1900024055., Competing Interests: Declaration of competing interest The authors declare no conflict of interest., (Copyright © 2021 The Italian Diabetes Society, the Italian Society for the Study of Atherosclerosis, the Italian Society of Human Nutrition and the Department of Clinical Medicine and Surgery, Federico II University.

Background: The atherogenic index of plasma (AIP) always remains in a potential association with arterial stiffness, however, this association has not been fully discovered and needs to be studied in depth in large hypertensive patient populations. The present analysis thus sought to further explore the association that exists between AIP and arterial stiffness in Chinese patients diagnosed with arterial hypertension., Methods: This cross-sectional study analyzed 4744 Chinese individuals with essential hypertension. AIP was defined as the base 10 logarithm of the ratio of plasma of triglycerides to high-density lipoprotein cholesterol levels indicated in molar concentrations. Measurement of arterial stiffness was carried out via brachial-ankle pulse wave velocity (baPWV)., Results: Data were adjusted for potential confounding variables, and multivariate linear regression analysis revealed AIP to be positively correlated with baPWV (β = 1.34, 95% CI: 0.96 to 1.72, P < 0.001). When AIP was instead treated as a categorical variable divided into quartiles, the same relationship was observed (P for trend < 0.001). We additionally found AIP and baPWV had a stronger positive association in individuals with a body mass index (BMI) < 24 kg/m 2 (P for interaction < 0.05)., Conclusion: AIP and arterial stiffness were positively correlated in essential hypertension patients in China, especially in those with a BMI < 24 kg/m 2 . Clinical trial registration ChiCTR1800017274.

Abstract: Whether LCZ696 (neprilysin inhibitor + valsartan) has greater advantages of blood pressure (BP) lowering than angiotensin II type 1 receptor blockers (ARBs) is unclear. To provide more detailed information about the benefits of LCZ696, we conducted a meta-analysis to evaluate the efficacy and safety of LCZ696 for short-term management of hypertension compared with ARBs. We searched PubMed, EMBASE, the Cochrane Library, and ClinicalTrials.gov, using relevant keywords. We used a random or fixed effects model to calculate the weighted mean difference (WMD) of changes in BP and the risk ratio (RR) for BP control rates and adverse events (AEs). In this meta-analysis, 9 studies were incorporated. Compared with ARBs, LCZ696 revealed a significant reduction in mean sitting systolic BP [msSBP; WMD -4.79 mm Hg; 95% confidence interval (CI): -5.46 to -4.11 mm Hg], mean sitting diastolic BP (msDBP; WMD -2.12 mm Hg; 95% CI: -2.53 to -1.71 mm Hg), mean sitting pulse pressure (msPP; WMD -2.79 mm Hg; 95% CI: -3.52 to -2.07 mm Hg), and mean ambulatory pulse pressure (maPP; WMD -2.96 mm Hg; 95% CI: -3.35 to -2.57 mm Hg). LCZ696 had a higher BP control rate than ARBs (OR = 1.55; 95% CI: 1.39 to 1.73). There was no significant difference between LCZ696 and ARBs in the incidence of AEs (RR = 1.10; 95% CI: 0.96 to 1.25) and discontinuations because of AEs (RR = 0.97; 95% CI: 0.54 to 1.32). Overall, in short-term treatment, LCZ696 has greater advantages of antihypertensive efficacy and the safety is not inferior to ARBs. Further long-term studies are required to rule out the potential risks of beta amyloid accumulation and the potential for Alzheimer's disease., Competing Interests: The authors report no conflicts of interest., (Copyright © 2021 Wolters Kluwer Health, Inc.

Objectives: This study aims to investigate the association between hsa&#95;circ&#95;0037897 and essential hypertension (EH) and to evaluate the diagnostic value of biomarker hsa&#95;circ&#95;0037897 in EH. Methods: This study included 92 EH patients and 92 sex- and age- (±3 years) matched subjects as control. qRT-PCR was performed to measure the expression level of circRNA and miRNA. Logistic regression analysis model was used to assess independent association between hsa&#95;circ&#95;0037897 and EH. Results: The expression level of hsa&#95;circ&#95;0037897 in EH patients was significantly higher ( p < .001) compared to the control group, while hsa-miR-145-5p had significantly lower expression( p = .002) than the control group. The area under the ROC curve (AUC) of hsa&#95;circ&#95;0037897 was 0.656. Furthermore, the AUC increased to 0.714 when hsa&#95;circ&#95;0037897 was combined with hsa-miR-145-5p, BMI and smoking. Conclusion: The present results suggested that the high expression of hsa&#95;circ&#95;0037897 may be a risk factor for EH, and hsa&#95;circ&#95;0037897 has certain diagnostic value for EH.

Purpose : Vitamin D deficiency is known that associated with hypertension. Microalbuminuria (MAU) is associated with increased cardiovascular morbidity and mortality. This study aimed to evaluate the relationship between 25-hydroxyvitamin D (25(OH)D) and MAU in newly diagnosed essential hypertension (NDEH) patients. Methods: A total of 116 patients with a diagnosis of NDEH were enrolled in the study. The diagnosis of hypertension was based on ABPM. Patients were divided into 2 groups according to 25(OH)D levels: Group 1: (25(OH)D)>20 ng/mL was defined as Vitamin D sufficiently (VDS), while Group 2: (25(OH)D)<20 ng/mL was defined Vitamin D deficiently (VDD). The relationship between 25(OH)D and MAU was analyzed. The results were analyzed using the SPSS program version 21. Results: The mean age of the patients was 58.4 ± 14.7 years and 60 (51.7%) of them were female. The prevalence of MAU was 18.9% and Vitamin D deficiency was 61.2% in NDEH. Linear regression analysis showed that 25(OH)D was independently related to MAU [β 0.643, 95% confidence interval 1.173-1.631, p = .011]. Besides, male gender, C-reactive protein, non-dipper hypertension, and diastolic blood pressure were independent risk factors associated with MAU in the multivariate analysis ( p < .05). Conclusion: Vitamin D deficiency is highly prevalent in NDEH patients. This study showed that the level of microalbuminuria was significantly higher in patients with 25(OH)D deficiency compared to patients with normal 25(OH)D levels. Vitamin D deficiency is independently related to microalbuminuria in NDEH.

Background: Essential hypertension and type 2 diabetes mellitus (T2DM) are two common chronic diseases that often coexist, and both of these diseases can cause heart damage. However, the additive effects of essential hypertension complicated with T2DM on left ventricle (LV) diastolic function have not been fully illustrated. This study aims to investigate whether T2DM affects the diastolic function of the LV in patients with essential hypertension using the volume-time curve from cardiac magnetic resonance (CMR)., Methods: A total of 124 essential hypertension patients, including 48 with T2DM [HTN(T2DM +) group] and 76 without T2DM [HTN(T2DM-) group], and 52 normal controls who underwent CMR scans were included in this study. LV volume-time curve parameters, including the peak ejection rate (PER), time to peak ejection rate (PET), peak filling rate (PFR), time to peak filling rate from end-systole (PFT), PER normalized to end-diastolic volume (PER/EDV), and PFR normalized to EDV (PFR/EDV), were measured and compared among the three groups. Multivariate linear regression analyses were performed to determine the effects of T2DM on LV diastolic dysfunction in patients with hypertension. Pearson correlation was used to analyse the correlation between the volume-time curve and myocardial strain parameters., Results: PFR and PFR/EDV decreased from the control group, through HTN(T2DM -), to HTN(T2DM +) group. PFT in the HTN(T2DM-) group and HTN(T2DM +) group was significantly longer than that in the control group. The LV remodelling index in the HTN(T2DM -) and HTN(T2DM +) groups was higher than that in the normal control group, but there was no significant difference between the HTN(T2DM -) and HTN(T2DM +) groups. Multiple regression analyses controlling for covariates of systolic blood pressure, age, sex, and heart rate demonstrated that T2DM was independently associated with PFR/EDV (β = 0.252, p < 0.05). The volume-time curve method has good repeatability, and there is a significant correlation between volume-time curve parameters (PER/EDV and PFR/EDV) and myocardial peak strain rate, especially circumferential peak strain rate, which exhibited the highest correlation (r = - 0.756 ~ 0.795)., Conclusions: T2DM exacerbates LV diastolic dysfunction in patients with essential hypertension. The LV filling model changes reflected by the CMR volume-time curve could provide more information for early clinical intervention.

Context: Identification of patients with endocrine forms of hypertension (EHT) (primary hyperaldosteronism [PA], pheochromocytoma/paraganglioma [PPGL], and Cushing syndrome [CS]) provides the basis to implement individualized therapeutic strategies. Targeted metabolomics (TM) have revealed promising results in profiling cardiovascular diseases and endocrine conditions associated with hypertension., Objective: Use TM to identify distinct metabolic patterns between primary hypertension (PHT) and EHT and test its discriminating ability., Methods: Retrospective analyses of PHT and EHT patients from a European multicenter study (ENSAT-HT). TM was performed on stored blood samples using liquid chromatography mass spectrometry. To identify discriminating metabolites a "classical approach" (CA) (performing a series of univariate and multivariate analyses) and a "machine learning approach" (MLA) (using random forest) were used.The study included 282 adult patients (52% female; mean age 49 years) with proven PHT (n = 59) and EHT (n = 223 with 40 CS, 107 PA, and 76 PPGL), respectively., Results: From 155 metabolites eligible for statistical analyses, 31 were identified discriminating between PHT and EHT using the CA and 27 using the MLA, of which 16 metabolites (C9, C16, C16:1, C18:1, C18:2, arginine, aspartate, glutamate, ornithine, spermidine, lysoPCaC16:0, lysoPCaC20:4, lysoPCaC24:0, PCaeC42:0, SM C18:1, SM C20:2) were found by both approaches. The receiver operating characteristic curve built on the top 15 metabolites from the CA provided an area under the curve (AUC) of 0.86, which was similar to the performance of the 15 metabolites from MLA (AUC 0.83)., Conclusion: TM identifies distinct metabolic pattern between PHT and EHT providing promising discriminating performance., (© The Author(s) 2020.

Background: The impact of diagnosing pediatric hypertension based on all three-24-hour, day and night ambulatory blood pressure (ABP) thresholds (combined ABP threshold) vs. conventionally used 24-hour ABP threshold is not known., Methods: In this cross-sectional, retrospective study from a tertiary care outpatient clinic, we evaluated the diagnosis of hypertension based on the 24-hour European Society of Hypertension (ESH) and combined ESH ABP thresholds in untreated children with essential hypertension. The American Academy of Pediatrics (AAP) and Fourth Report thresholds were used to classify office blood pressure (OBP)., Results: In 159 children, aged 5-18 years, the 24-hour ESH and combined ESH thresholds classified 82% (95th confidence interval (CI) 0.68, 0.97) ABP similarly with the area under the curve (AUC) of 0.86 (95th CI 0.80, 0.91). However, the AUC of the 2 ABP thresholds was significantly higher in the participants with office hypertension than office normotension, with OBP classified by the AAP (AUC 0.93, 95th CI 0.84, 0.98 vs. 0.80, 95th CI 0.71, 0.88) or Fourth Report (AUC 0.93, 95th CI 0.83, 0.98 vs. 0.81, 95th CI 0.73, 0.88) threshold. With OBP classified by the either OBP threshold, the combined ESH threshold diagnosed significantly more masked hypertension (MH) (difference 15%, 95th CI 4.9, 24.7; P = 0.00); however, the diagnosis of white coat hypertension (WCH) by the 2 ABP thresholds did not differ significantly (difference 4%, 95th CI 1.8, 10; P = 0.16)., Conclusions: In children with essential hypertension, the 24-hour and combined ESH thresholds have a stronger agreement for diagnosing WCH than MH., (© American Journal of Hypertension, Ltd 2020.

Systolic and diastolic hypertension independently predict the risk of adverse cardiovascular events. It remains unclear how systolic pressure, diastolic pressure, and other patient characteristics influence the initial diagnosis of hypertension. Here, we use a cohort of 146,816 adults in a large healthcare system to examine how elevated systolic and/or diastolic blood pressure measurements influence initial diagnosis of hypertension and how other patient characteristics influence the diagnosis. Thirty-four percent of the cohort were diagnosed with hypertension within 1 year. In multivariable logistic regression of the diagnosis of hypertension, controlling for covariates, isolated systolic hypertensive measures (odds ratio [OR] 0.42 [95% confidence interval {CI} 0.41 to 0.43]) and isolated diastolic hypertensive measures (OR 0.32 [95% CI 0.31 to 0.33]) were less likely to lead to hypertension diagnosis when compared with combined hypertensive measures. Higher levels of systolic blood pressure had a greater impact on hypertension diagnosis (OR 1.77 [95% CI 1.75 to 1.79] per Z-score) than did higher levels of diastolic blood pressure (OR 1.34 [95% CI 1.32 to 1.36] per Z-score). Older age, non-white race/ethnicity, and medical comorbidities all predicted the establishment of a diagnosis of hypertension. Isolated systolic and isolated diastolic hypertension are underdiagnosed in clinical practice, and several patient-centered factors also strongly influence whether a diagnosis is made. In conclusion, our findings uncover a care gap that can be closed with increased attention to the independent influence of systolic and diastolic hypertension and the various patient-centered factors that may impact hypertension diagnosis., (Copyright © 2020 Elsevier Inc.

Aim: Essential hypertension (EH) is one of the most important public health problems worldwide. However, the pathogenesis of EH is unclear and early diagnostic methods are lacking. Metabolomics demonstrates great potential for biomarker discovery and the mechanistic exploration of metabolic diseases., Data Synthesis: This review included human and animal metabolomics studies related to EH in the PubMed and Web of Science databases between February 1996 and May 2020. The study designs, EH standards, and reported metabolic biomarkers were systematically examined and compared. The pathway analysis was conducted through the online software MetaboAnalyst 4.0. Twenty-two human studies and fifteen animal studies were included in this systematic review. There were many frequently reported biomarkers with consistent trends (e.g., pyruvate, lactic acid, valine, and tryptophan) in human and animal studies, and thus had potential as biomarkers of EH. In addition, several shared metabolic pathways, including alanine, aspartate, and glutamate metabolism, aminoacyl-tRNA biosynthesis, and arginine biosynthesis, were identified in human and animal metabolomics studies. These biomarkers and pathways, closely related to insulin resistance, the inflammatory state, and impaired nitric oxide production, were demonstrated to contribute to EH development., Conclusions: This study summarized valuable metabolic biomarkers and pathways that could offer opportunities for the early diagnosis or prediction of EH and the discovery of the metabolic mechanisms of EH., Competing Interests: Declaration of competing interest The authors state that there are no conflicts of interests., (Copyright © 2020 The Italian Diabetes Society, the Italian Society for the Study of Atherosclerosis, the Italian Society of Human Nutrition and the Department of Clinical Medicine and Surgery, Federico II University.

Background: Essential hypertension (EH) is an inflammatory disease, and endothelial dysfunction induced by chronic inflammation is one of the pathogeneses of EH. The expression of some inflammatory mediators may be regulated by the interaction of circular RNAs (circRNAs) and microRNAs (miRNAs)., Methods: An Agilent human circRNA microarray was used to identify the expression profile of circRNAs in EH. qRT-PCR was used to evaluate the relative expression of circRNAs in 48 pairs of human whole blood samples (sex and age ± 3 years matched) and endothelial cells. TNF-α was applied to induce endothelial cells inflammation. CircRNA-miRNA network was predicted by MiRanda software., Results: There were 287 circRNAs differentially expressed in the microarray. The top 10 up-regulated circRNAs in the EH group were hsa&#95;circ&#95;0014243, hsa&#95;circ&#95;0133228, hsa-circRNA14116-3, hsa&#95;circ&#95;0079536, hsa-circRNA13649-1, hsa&#95;circ&#95;0117886, hsa&#95;circ&#95;0007075, hsa-circRNA15285-1, hsa-circRNA10088-9, and hsa-circRNA14119-10; the top 10 down-regulated circRNAs were hsa&#95;circ&#95;0100094, hsa&#95;circ&#95;0127342, hsa&#95;circ&#95;0093773, hsa&#95;circ&#95;0096334, hsa&#95;circ&#95;0131618, hsa&#95;circ&#95;0063886, hsa&#95;circ&#95;0097804, hsa&#95;circ&#95;0126640, hsa-circRNA8935-1, and hsa&#95;circ&#95;0039978 (fold change in descending order). Hsa&#95;circ&#95;0105015 has two predicted binding sites with hsa-miR-637. The relative expression of hsa&#95;circ&#95;0105015 in EH patients was significantly higher than healthy controls (P = .002), and similar results appeared in TNF-α-induced endothelial cells. The area under the curve after hsa&#95;circ&#95;0105015 combined with hsa-miR-637 was 0.703, P < .001., Conclusion: Hyperexpression of hsa&#95;circ&#95;0105015 is a significant risk factor of EH and its association with EH involves inflammatory pathways. Hyperexpression of hsa&#95;circ&#95;0105015 combined with hypoexpression of hsa-miR-637 indicates vascular inflammation or endothelial dysfunction and has potential as a biomarker for early diagnosis of EH., (© 2020 The Authors.

Background and Aims: CKD patients have a high prevalence of LVH and this leads to an increase of cardiovascular risk. The aim of this study was to assess the prevalence of left ventricular hypertrophy (LVH) and left ventricular geometry in a group of 293 hypertensive patients with stage 2-5 chronic kidney disease (CKD), compared with 289 essential hypertensive patients with normal renal function., Methods and Results: All patients underwent echocardiographic examination. Patients on stage 1 CKD, dialysis treatment, or with cardiovascular diseases were excluded. LVH was observed in 62.8% of patients with CKD and in 51.9% of essential hypertensive patients (P < 0.0001). We found increasingly higher left ventricular diameters, thicknesses, and mass from stage 2-5 CKD. Distribution of concentric and eccentric LVH was not very different between the two groups. However, after introducing mixed hypertrophy, the difference between the two groups group was disclosed (P = 0.027). Multiple regression analysis confirmed that the association between renal function and left ventricular mass (β -0.287; P < 0.0001) was independent by potential confounders. Diastolic function was significantly worse in patients with CKD, especially in more advanced stages., Conclusion: Our study confirms that LVH is highly prevalent in patients with CKD, especially by using the most recent cut off; in this population, LVH is often characterized by the simultaneous increase of wall thicknesses and diameters with negative effects on diastolic function., (Copyright © 2020 The Italian Diabetes Society, the Italian Society for the Study of Atherosclerosis, the Italian Society of Human Nutrition and the Department of Clinical Medicine and Surgery, Federico II University.
