[ABSTRACT]. Objective. To evaluate the implementation of HEARTS strategies in a community in the Bolivarian Republic of Venezuela. Methods. Quasi-experimental study evaluating the cascade of care, driving factors, and maturity and performance indicators four months after implementation of the HEARTS initiative in 52 patients with high blood pressure (BP) in the community of La Marroquina. The data were processed using SPSS® Statistics, version 25.0. Student's t-distribution and chi-square tests were applied to determine statistical significance. Results. Fifty patients, 63.5% of them with a low educational level and low or very low socioeconomic status, completed the four-month monitoring period. At baseline, 11.5% had controlled BP and 40.4% initiated monotherapy. By the fourth month, 100% of patients with high BP had been diagnosed, 92% had received treatment, and 52% had achieved control of their BP. Seventy-two percent were receiving combined therapy. Seventy percent of the hypertensive individuals maintained blood pressure levels <140/90 mmHg. The maturity index score was 4 of 5, and the performance index was classified as incipient. Conclusion. This work shows that, in a short time, a good maturity index was achieved through the implementation, by medical and supervised non-medical personnel, of a standardized protocol for diagnosis, treatment, and monitoring of high blood pressure in a rural population. Rates of diagnosis, treatment, and BP control improved, with incipient performance results. Sustaining this initiative will have a major impact on the health of this population. Its implementation as a national public health policy is recommended.

Burden of non-communicable diseases among women of reproductive age in Kenya: a cross-sectional study.

OBJECTIVE: To examine the burden of non-communicable diseases (NCDs) among women of reproductive age in Kenya, highlighting the prevalence and risk factors. DESIGN: Cross-sectional design based on the 2022 Kenya Demographic and Health Survey. SETTING: Kenya. PRIMARY OUTCOMES: Predict the burden of hypertension, diabetes, heart disease, lung disease, arthritis, depression, anxiety, breast and cervical cancer. RESULTS: Overall, 15.9% of Kenyan women aged 15-49 years were living with at least one NCD. The most prevalent NCD among this cohort was hypertension (8.7%) followed by arthritis (2.9%) and depression (2.8%). Our findings revealed that increasing age, increasing wealth, being married or formerly married, being overweight or obese, consuming alcohol and some occupations were risk factors of NCDs among women of reproductive age in Kenya. CONCLUSION: We conclude that hypertension is the most prevalent NCD among women of reproductive age in Kenya. The findings underscore the multifaceted nature of NCD risk factors in Kenya, emphasising the importance of targeted interventions that consider age, economic status, education, marital status, occupation and lifestyle factors.

Equitable Care for Hypertension: Blood Pressure and Patient-Reported Outcomes of the RICH LIFE Cluster Randomized Trial.

BACKGROUND: Disparities in hypertension control are well documented but underaddressed. METHODS: RICH LIFE (Reducing Inequities in Care of Hypertension: Lifestyle Improvement for Everyone) was a 2-arm, cluster randomized trial comparing the effect on blood pressure (BP) control (systolic BP ≤140 mm Hg, diastolic BP ≤90 mm Hg), patient activation, and disparities in BP control of 2 multilevel interventions, standard of care plus (SCP) and collaborative care/stepped care (CC/SC). SCP included BP measurement standardization, audit and feedback, and equity-leadership training. CC/SC added roles to address social or medical needs. Primary outcomes were BP control and patient activation at 12 months. Generalized estimating equations and mixed-effects regression models with fixed effects of time, intervention, and their interaction compared change in outcomes at 12 months from baseline. RESULTS: A total of 1820 adults with uncontrolled BP and ≥1 other risk factors enrolled in the study. Their mean age was 60.3 years, and baseline BP was 152.3/85.5 mm Hg; 59.4% were women; 57.4% were Black, 33.2% were White, and 9.4% were Hispanic; 74% had hyperlipidemia; and 45.1% had type 2 diabetes. CC/SC did not improve BP control rates more than SCP. Both groups achieved statistically and clinically significant BP control rates at 12 months (CC/SC: 57.3% [95% CI, 52.7%-62.0%]; SCP: 56.7% [95% CI, 51.9%-61.5%]). Pairwise comparisons between racial and ethnic groups showed overall no significant differences in BP control at 12 months. Patients with coronary heart disease showed greater achievement of BP control in CC/SC than in SCP (64.0% [95% CI, 54.1%-73.9%] versus 50.8% [95% CI, 42.6%-59.0%]; P=0.04), as did patients in rural areas (67.3% [95% CI, 49.8%-84.8%] versus 47.8% [95% CI, 32.4%-63.2%]; P=0.01). Individuals in both arms experienced statistically and clinically significant reductions in mean systolic BP (CC/SC: -13.8 mm Hg [95% CI, -15.2 to -12.5]; SCP: -14.6 mm Hg [95% CI, -15.9 to -13.2]) and diastolic BP (CC/SC: -6.9 mm Hg [95% CI, -7.8 to -6.1]; SCP: -5.5 mm Hg [95% CI, -6.4 to -4.6]) over time. The difference in diastolic BP reduction between CC/SC and SCP over time was statistically significant (-1.4 mm Hg [95% CI, -2.6 to -0.2). Patient activation did not differ between arms. CC/SC showed greater improvements in patient ratings of chronic illness care (Patient Assessment of Chronic Illness Care score) over 12 months (0.12 [95% CI, 0.02-0.22]). CONCLUSIONS: Adding a collaborative care team to enhanced standard of care did not improve BP control but did improve patient ratings of chronic illness care.

[A quantitative MRI comparative study of imaging markers for cerebral small vessel disease in the middle-aged and elderly patients with and without hypertension].

Objective: To explore the difference of MRI markers of small cerebral vascular disease in middle-aged and elderly patients with hypertension and non-hypertension. Methods: A cross-sectional study. The clinical data of 316 patients who underwent head MRI with susceptibility weighted imaging scans at the Affiliated Zhongda Hospital of Southeast University from November 2013 to August 2022 were retrospectively analyzed, including 190 males and 126 females, with the age of (71.6±8.9)years. According to the history of hypertension, the patients were divided into hypertension group(n=259) and the non-hypertension group(n=57). The patients in the non-hypertension group were further divided into abnormal blood pressure group on admission (n=19) and normal blood pressure group on admission (n=38). The imaging features of different CSVD dimensions in the patient's images were quantified or graded and compared between hypertensive and non-hypertensive patient groups. Deep learning methods were employed to segment white matter lesions, and voxel-wise analysis was conducted to investigate the differences in whole-brain white matter lesion probability between patients in both groups. Spearman correlation analysis was used to analyze the correlation between hypertension and small cerebral vascular disease. Results: Compared with the non-hypertensive group, the cerebral microhemorrhage count, deep microhemorrhage count, basal ganglia level lacunae count, perivascular space (EPVS) grade of hemioval center level and EPVS grade of basal ganglia level were higher in the hypertensive group (all P<0.05). The cerebral microhemorrhage count [3.0(1.0, 15.0) vs 1.0 (0, 4.2)], deep microhemorrhage count [1.0 (0, 7.0) vs 1.0 (0, 4.2)] and EPVS classification at basal ganglium level [2.0(1.0, 3.0) vs 1.0(1.0, 2.0)] in the group with history of hypertension were higher than those in the group with normal blood pressure at admission (all P<0.05). The EPVS grade at the central level of the semiovale in the hypertension group was higher than that of the group with normal blood pressure at admission [2.0(1.0, 2.0) vs 1.0 (1.0, 2.0)], and also higher than that of the group with abnormal blood pressure at admission [2.0(1.0, 2.0) vs 1.0(1.0, 2.0)](both P<0.05). Voxel-by-voxel analysis showed no significant difference in the probability of white matter lesions in the whole brain between patients with and without a history of hypertension, but patients with a history of hypertension showed more extensive para-ventricular white matter hypersignaling than those without a history of hypertension. Spearman correlation analysis showed that hypertension grade was correlated with the number of microbleeding lesions in depth (r=0.149), the number of lacunae lesions in the center of the hemioval (r=0.209), and the number of lacunae lesions in the basal ganglia (r=0.204) (all P<0.05). Conclusions: Chronic hypertension can affect different dimensions of small vessel disease imaging, primarily manifested in the increases of deep microbleed counts and the EPVS grade.

Gstp1 negatively regulates blood pressure in hypertensive rat via promoting APLNR ubiquitination degradation mediated by Nedd4.

Hypertension is a leading risk factor for disease burden worldwide. Vascular contraction and remodeling contribute to the development of hypertension. Glutathione S-transferase P1 (Gstp1) plays several critical roles in both normal and neoplastic cells. In this study, we investigated the effect of Gstp1 on hypertension as well as on vascular smooth muscle cell (VSMC) contraction and phenotypic switching. We identified the higher level of Gstp1 in arteries and VSMCs from hypertensive rats compared with normotensive rats for the first time. We then developed Adeno-associated virus 9 (AAV9) mediated Gstp1 down-regulation and overexpression in rats and measured rat blood pressure by using the tail-cuff and the carotid catheter method. We found that the blood pressure of spontaneously hypertensive rats (SHR) rose significantly with Gstp1 down-regulation and reduced apparently after Gstp1 overexpression. Similar results were obtained from the observations of 2-kidney-1-clip renovascular (2K1C) hypertensive rats. Gstp1 did not influence blood pressure of normotensive Wistar-Kyoto (WKY) rats and Sprague-Dawley (SD) rats. Further in vitro study indicated that Gstp1 knockdown in SHR-VSMCs promoted cell proliferation, migration, dedifferentiation and contraction, while Gstp1 overexpression showed opposite effects. Results from bioinformatic analysis showed that the Apelin/APLNR system was involved in the effect of Gstp1 on SHR-VSMCs. The rise in blood pressure of SHR induced by Gstp1 knockdown could be reversed by APLNR antagonist F13A. We further found that Gstp1 enhanced the association between APLNR and Nedd4 E3 ubiquitin ligases to induce APLNR ubiquitination degradation. Thus, in the present study, we discovered a novel anti-hypertensive role of Gstp1 in hypertensive rats and provided the experimental basis for designing an effective anti-hypertensive therapeutic strategy.

Patient-Specific Factors Predicting Renal Denervation Response in Patients With Hypertension: A Systematic Review and Meta-Analysis.

BACKGROUND: The accurate selection of patients likely to respond to renal denervation (RDN) is crucial for optimizing treatment outcomes in patients with hypertension. This systematic review was designed to evaluate patient-specific factors predicting the RDN response. METHODS AND RESULTS: We focused on individuals with hypertension who underwent RDN. Patients were categorized based on their baseline characteristics. The primary outcome was blood pressure (BP) reduction after RDN. Both randomized controlled trials and nonrandomized studies were included. We assessed the risk of bias using corresponding tools and further employed the Grading of Recommendations Assessment, Development, and Evaluation approach to assess the overall quality of evidence. A total of 50 studies were ultimately included in this systematic review, among which 17 studies were for meta-analysis. Higher baseline heart rate and lower pulse wave velocity were shown to be associated with significant antihypertensive efficacy of RDN on 24-hour systolic BP reduction (weighted mean difference, -4.05 [95% CI, -7.33 to -0.77]; weighted mean difference, -7.20 [95% CI, -9.79 to -4.62], respectively). In addition, based on qualitative analysis, higher baseline BP, orthostatic hypertension, impaired baroreflex sensitivity, and several biomarkers are also reported to be associated with significant BP reduction after RDN. CONCLUSIONS: In patients with hypertension treated with the RDN, higher heart rate, and lower pulse wave velocity were associated with significant BP reduction after RDN. Other factors, including higher baseline BP, hypertensive patients with orthostatic hypertension, BP variability, impaired cardiac baroreflex sensitivity, and some biomarkers are also reported to be associated with a better BP response to RDN.

Prevalence of interarm blood pressure difference is notably higher in women; the Viborg population-based screening program (VISP).

BACKGROUND: Bilateral blood pressure (BP) measurement is important in cardiovascular prevention for identifying systolic interarm BP difference (IAD) and hypertension. We investigated sex-stratified IAD prevalence and its associations and coexistence with screen-detected peripheral atherosclerosis and hypertension. Furthermore, we determined the proportion misclassified as non-hypertensive when using the lower versus the higher reading arm. METHODS: This sub-study formed part of the Viborg Screening Program (VISP), a cross-sectorial population-based cardiovascular screening programme targeting 67-year-old Danes. VISP includes screening for peripheral atherosclerosis (lower extremity arterial disease and carotid plaque), abdominal aortic aneurysm, hypertension, diabetes mellitus, and cardiac disease. Self-reported comorbidities, risk factors, and medication use were also collected. Among 4,602 attendees, 4,517 (82.1%) had eligible bilateral and repeated BP measurements. IAD was defined as a systolic BP difference ≥ 10 mmHg. IAD-associated factors (screening results and risk factors) were estimated by logistic regression; proportional coexistence was displayed by Venn diagrams (screening results). RESULTS: We included 2,220 women (49.2%) and 2,297 men (50.8%). IAD was more predominant in women (26.8%) than men (21.0%) (p < 0.001). This disparity persisted after adjustment [odds ratio (OR) 1.53; 95% confidence interval (CI) 1.32-1.77]. No other association was recorded with the conditions screened for, barring potential hypertension: BP 140-159/90-99 mmHg (OR 1.68, 95% CI 1.44-1.97) and BP ≥ 160/100 mmHg (OR 1.82, 95% CI 1.49-2.23). Overall, IAD and BP ≥ 160/100 mmHg coexistence was 4% in women and 5% in men; for BP ≥ 140/90 mmHg, 13% and 14%, respectively. Among those recording a mean BP ≥ 140/90 mmHg in the higher reading arm, 14.5% of women and 15.3% of men would be misclassified as non-hypertensive compared with the lowest reading arm. CONCLUSION: Female sex was an independent factor of IAD prevalence but not associated with other arterial lesions. Approximately 15% needed reclassification according to BP ≥ 140/90 mmHg when the lower rather than the higher reading arm was used; verifying bilateral BP measurements improved detection of potential hypertension. In future, the predictive value of sex-stratified IAD should be assessed for cardiovascular events and death to verify its potential as a screening tool in population-based cardiovascular screening. TRIAL REGISTRATION FOR VISP: NCT03395509:10/12/2018.

Impact of RAAS Receptors and Membrane-Bound Transporter System in the Left Ventricle during the Long-Term Control of Hypertension.

The Renin-Angiotensin-Aldosterone System (RAAS) has been implicated in systemic and neurogenic hypertension. The infusion of RAAS inhibitors blunted arterial pressure and efficacy of use-dependent synaptic transmission in sympathetic ganglia. The current investigation aims to elucidate the impact of RAAS-mediated receptors on left ventricular cardiomyocytes and the role of the sarcolemma-bound carrier system in the heart of the hypertensive transgene model. A significant increase in mRNA and the protein expression for angiotensin II (AngII) receptor subtype-1 (AT1R) was observed in (mREN2)27 transgenic compared to the normotensive rodents. Concurrently, there was an upregulation in AT1R and a downregulation in the MAS1 proto-oncogene protein receptor as well as the AngII subtype-2 receptor in hypertensive rodents. There were modifications in the expressions of sarcolemma Na+-K+-ATPase, Na+-Ca2+ exchanger, and Sarcoendoplasmic Reticulum Calcium ATPase in the transgenic hypertensive model. These observations suggest chronic RAAS activation led to a shift in receptor balance favoring augmented cardiac contractility and disruption in calcium handling through modifications of membrane-bound carrier proteins and blood pressure. The study provides insight into mechanisms underlying RAAS-mediated cardiac dysfunction and highlights the potential value of targeting the protective arm of AngII in hypertension.

Age-Related Effects of AT1 Receptor Antagonist Losartan on Cognitive Decline in Spontaneously Hypertensive Rats.

Both hypertension and aging are known to increase the vulnerability of the brain to neurovascular damage, resulting in cognitive impairment. The present study investigated the efficacy of the antihypertensive drug losartan on age- and hypertension-associated cognitive decline and the possible mechanism underlying its effect in spontaneously hypertensive rats (SHRs). Losartan was administered (10 mg/kg, i.p. for 19 days) to 3- and 14-month-old SHRs. Age-matched Wistar rats were used as controls. Working memory, short-term object recognition, and spatial memory were assessed using the Y-maze, object recognition test (ORT) and radial arm maze (RAM) test. The expression of markers associated with aging, oxidative stress, and memory-related signaling was assessed in the frontal cortex (FC) and hippocampus. Motor activity measured over 24 h was not different between groups. Middle-aged vehicle-treated SHRs showed poorer performance in spontaneous alternation behavior (SAB) and activity in the first Y-maze test than their younger counterparts, suggesting age-related reduced "decision making" and reactivity in a novel environment. Losartan improved the age- and hypertension-induced decline in short-term recognition and spatial memory measured in the ORT and the second Y-maze test, particularly in the middle-aged rats, but was ineffective in the young adult rats. Changes in memory and age-related markers such as cAMP response element-binding protein (CREB) and amyloid-ß1-42 (Aß1-42) and increased oxidative stress were observed in the hippocampus but not in the FC between young adult and middle-aged vehicle-treated SHRs. Losartan increased CREB expression while reducing Aß1-42 levels and concomitant oxidative stress in middle-aged SHRs compared with vehicle-treated SHRs. In conclusion, our study highlights the complex interplay between hypertension, aging, and cognitive impairment. It suggests that there is a critical time window for therapeutic intervention with angiotensin II type 1 receptor blockers.

Overview of clinical status, treatment, and long-term outcomes of pediatric autosomal-dominant polycystic kidney disease: a nationwide survey in Taiwan.

This retrospective study investigated the incidence, medication use, and outcomes in pediatric autosomal-dominant polycystic kidney disease (ADPKD) using Taiwan's National Health Insurance Research Database (NHIRD). A 1:4 matched control group of individuals included in the NHIRD during the same period was used for comparative analyses. A total of 621 pediatric patients were identified from 2009 to 2019 (mean age, 9.51 ± 6.43 years), and ADPKD incidence ranged from 2.32 to 4.45 per 100,000 individuals (cumulative incidence, 1.26-1.57%). The incidence of newly developed hypertension, anti-hypertensive agent use, nephrolithiasis, and proteinuria were significantly higher in the ADPKD group than the non-ADPKD group (0.7 vs. 0.04, 2.26 vs. 0.30, 0.4 vs. 0.02, and 0.73 vs. 0.05 per 100 person-years, respectively). The adjusted hazard ratios for developing hypertension, proteinuria, nephrolithiasis and anti-hypertensive agent use in cases of newly-diagnosed pediatric ADPKD were 12.36 (95% CI 4.92-31.0), 13.49 (95% CI 5.23-34.79), 13.17 (95% CI 2.48-69.98), and 6.38 (95% CI 4.12-9.89), respectively. The incidence of congenital cardiac defects, hematuria, urinary tract infections, gastrointestinal diverticulosis, dyslipidemia, and hyperuricemia were also higher in the ADPKD group. Our study offers valuable insights into the epidemiology of pediatric ADPKD in Taiwan and could help in formulating guidelines for its appropriate management.

Interrelation of daily blood pressure profile with left ventricular myocardial hypertrophy in men of working age with hypertension.

OBJECTIVE: Aim: To analyze the relationship between daily blood pressure biorhythms and left ventricular myocardial hypertrophy in working-age men with arterial hypertension. PATIENTS AND METHODS: Materials and Methods: Fifty-seven men with AH (mean age: 44.6±1.3 years) underwent Echo-CG and daily ABPM. Non-dipper and night-peaker patterns indicated BP biorhythm disturbances, while normal dipper and over-dipper patterns indicated undisturbed BP biorhythms. LVH was defined as LMMI > 115 g/m^2. RESULTS: Results: About 60% of participants exhibited diurnal BP rhythm disorders, with a higher prevalence of LVH in this group compared to those with normal BP biorhythms (32% vs. 22%, p>0,05). Patients with normal daily BP biorhythms had significantly higher circadian indices of HR, systolic and diastolic BP, and double product compared to those with disturbed BP rhythms. CONCLUSION: Conclusions: In young men with "non-dipper" and "night-peaker" patterns, LVH appears to be more pronounced than in those with normal daily BP biorhythms. This approach may optimize the timing of antihypertensive drug administration.

Correlation between peripheral immature platelet level and coronary immature platelet levels in coronary artery disease: an observational study in cardiac referral centre in East Java, Indonesia.

OBJECTIVE: To investigate the correlation between peripheral and coronary immature platelet, and factors that may predict coronary immature platelet levels. METHODS: The cross-sectional, observational, analytical study was conducted at the Cardiovascular Diagnostic and Intervention Centre of Dr Soetomo General Academic Hospital, Surabaya, Indonesia, from November 2017 to January 2018, and comprised patients of either gender with coronary artery disease. Peripheral and coronary blood samples were retrieved during coronary catheterisation. Immature platelet fraction was acquired by examining whole blood samples analysed through automated flow cytometry. Relationship between peripheral and coronary immature platelet fractions and counts were analysed using parametric correlation test, followed by linear regression analysis model of variables that influenced coronary immature platelet fraction. The statistical analysis was carried out using SPSS Statistics for Windows, Version 25.0 (IBM Corp, Armonk, NY, USA). RESULTS: Of the 70 patients, 55(78.6%) were males and 15(21.4%) were females. The overall mean age was 57±5.32 years. There were 35(50%) patients with a history of smoking, and 34(48.6%) had hypertension and dyslipidaemia. Mean peripheral immature platelet fraction was 3.86±1.84% and mean coronary immature platelet fraction was 3.63±1.7%. There was a robust positive and significant correlation (r=0.882; p<0.001) between immature platelet levels in peripheral and coronary blood. Peripheral immature platelet and glycated haemoglobin >7.5 were independent predictors of coronary immature platelet (p=0.001). CONCLUSIONS: There was a strong correlation between immature platelet levels in peripheral and coronary blood.

Clinical findings and electrocardiography predicted mortality among COVID-19 patients with pre-existing hypertension: A cross-sectional study of East Java Province, Indonesia.

OBJECTIVE: To evaluate the factors associated with mortality among coronavirus disease-2019 patients with preexisting hypertension. METHODS: The retrospective, cross-sectional study was conducted from June 15 to July 7, 2021, after approval from Dr Soetomo General Province Hospital, Indonesia, and comprised data from the coronavirus disease-2019 registry in the East Java province of Indonesia from March 2020 to June 2021. Data was collected for adult patients infected by coronavirus disease-2019 with pre-existing hypertension Data was analysed using SPSS 23. RESULTS: Of the 2,732 patients in the registry, 425(15.6%) with median age 56.5 years (interquartile range: 50-64 years) had pre-existing hypertension. Of them, 251(59.06%) were males, and 110(25.9%) had died while in hospital. Mortality was associated with older age; higher white blood cell counts at admission and lower platelet count (p<0.05). In addition, electrocardiogram parameters associated with mortality were faster heart rate and ST abnormality (p<0.05). CONCLUSIONS: Older age, high white blood cell level, lower platelet count, faster heart rate, and ST abnormality at admission were found to be the predictors of mortality among hospitalised coronavirus disease-2019 patients with pre-existing hypertension.

Wellens Syndrome in a patient with a history of hypertension and chronic obstructive pulmonary disease: a case report.

Wellens syndrome, an ST Elevation Myocardial Infarction (STEMI) equivalent, is also known as T-wave left anterior descending (LAD) coronary artery disease. Wellens syndrome is characterized by a unique electrocardiogram (ECG) pattern that suggests a significant stenosis in the left anterior descending coronary artery that warrants immediate intervention. Hereby, we present a case report of Wellens syndrome in a patient with a history of hypertension and chronic obstructive pulmonary disease (COPD) that may be potentially mistaken for pseudo- Wellens syndrome because the ECG pattern mimics left ventricular strain pattern (LVSP) in left ventricular hypertrophy (LVH). Thus, cautious examination of recent chest pain and ECG is important to differentiate Wellens syndrome and LVSP in patients with hypertension and COPD to perform early detection and aggressive intervention since they may help to lessen the adverse results.

Identifying pulmonary embolism - high risk patients after total knee replacement: systematic review.

OBJECTIVE: To determine the incidence, onset, risk factors and mortality of pulmonary embolism in total knee replacement patients. METHODS: The systematic review was conducted in September 2022, and comprised search on PubMed, ScienceDirect, Scopus and Crossref databases for studies published from 1977 till September 7, 2022, in the English language related to the incidence of pulmonary embolism after primary total knee replacement. Cochrane Handbook for Systematic Reviews of Interventions was used to assess risk of bias, and the Newcastle-Ottawa Scale was used to assess the quality of evidence. RESULTS: Of the 3,910 studies initially identified, 66(1.68%) were analysed in detail, which together had 13,258,455 total knee replacement patients. Pulmonary embolism was reported in 76,515(0.58%) cases. The onset of pulmonary embolism ranged 2-150 days post-surgery. Patients with older age, diabetes mellitus, higher body mass index, atrial fibrillation, previous venous thromboembolism, high Charlson Comorbidity Index score, hypertension, arrhythmia and chronic heart failure were at significantly higher risk (p<0.05). The overall mortality rate of pulmonary embolism in such cases ranged 10.53-100%. CONCLUSIONS: Pulmonary embolism is a rare complication after orthopaedic surgery, but it has a very high mortality rate. By recognising the risk factors, attending physicians can optimise the use of chemoprophylaxis, thus preventing pulmonary embolism.

Cardiovascular events according to blood pressure thresholds recommended by ACC/AHA.

AIM: The latest guidelines from ACC/AHA define hypertension at systolic blood pressure (SBP) 130-139 mmHg or diastolic blood pressure (DBP) 80-89 mmHg in contrast to guidelines from ESC/ESH defining hypertension at SBP ≥ 140 mmHg or DBP ≥ 90 mmHg. The aim was to determine whether the ACC/AHA definition of hypertension identifies persons at elevated risk for future cardiovascular outcome. METHODS: In a Danish prospective cardiovascular study, 19,721 white men and women aged 20-98 years were examined up to five occasions between 1976 and 2015. The population was followed until December 2018. The ACC/AHA definition of the BP levels were applied: Normal: SBP <120 mmHg and DBP <80 mmHg, Elevated: SBP 120-129 mmHg and DBP <80 mmHg, Stage 1: SBP 130-139 mmHg or DBP 80-89 mmHg, Stage 2: SBP ≥140 mmHg or DBP ≥90 mmHg. Absolute 10-year risk was calculated taking repeated examinations, covariates, and competing risk into account. RESULTS: For all outcomes, the 10-year risk in stage 1 hypertension did not differ significantly from risk in subjects with normal BP: The 10-year risk of cardiovascular events in stage 1 hypertension was 14.1% [95% CI 13.2;15.0] and did not differ significantly from the risk in normal BP at 12.8% [95% CI 11.1;14.5] (p = 0.19). The risk was highest in stage 2 hypertension 19.4% [95% CI 18.9;20.0] and differed significantly from normal BP, elevated BP, and stage 1 hypertension (p < 0.001). The 10-year risk of cardiovascular death was 6.6% [95% CI 5.9;7.4] in stage 1 hypertension and did not differ significantly from the risk in normal BP at 5.7% [95% CI 4.1;7.3] (p = 0.33). CONCLUSIONS: Stage 1 hypertension as defined by the ACC/AHA guidelines has the same risk for future cardiovascular events as normal BP. In contrast, the definition of hypertension as suggested by ESC/ESH identifies patients with elevated risk of cardiovascular events.

Until 2017, there was worldwide agreement on defining hypertension at systolic blood pressure (SBP) ≥ 140 mmHg or diastolic blood pressure (DBP) ≥ 90 mmHg.In 2017, the American Cardiology Societies (ACC and AHA) lowered the threshold for defining hypertension at SBP 130-139 mmHg or DBP 80-89 mmHg.Lowering the threshold might make healthy persons sick if the thresholds do not identify persons at high risk.Unnecessary medical treatment is associated with high economic cost for the health care systems.We wanted to explore whether applying the American BP definition in a Scandinavian population identified persons with elevated risk for cardiovascular disease.As part of the Copenhagen City Heart study, 19,721 men and women aged 20-98 years were followed from 1976.They went through up to five examinations between 1976 and 2018 including BP measurements.We applied the American BP thresholds and followed the persons until death or 2018.In Denmark all citizens have a unique identification number which is linked to all health care contacts and administrative registers.We used advanced statistical methods and linked the BP measurements with the data for cardiovascular disease and death date from the Danish registries for each person.The results showed that the American definition of hypertension has same risk for future cardiovascular disease as the definition of normal BP.This means that healthy persons will be diagnosed with hypertension if the US guidelines were applied in Denmark.

The association between serum folate and elderly diastolic hypertension: results from the NHANES (2007-2018).

AIM: To explore the association between serum folate concentration and the prevalence of elderly diastolic hypertension. This study aims to identify potential relationships that could inform further research into the mechanisms underlying hypertension management. METHODS: Data from six NHANES cycles (2007-2008, 2009-2010, 2011-2012, 2013-2014, 2015-2016, and 2017-2018) were analysed for individuals aged over 60. Weighted logistic regression estimated odds ratios (ORs) and 95% confidence intervals (CIs). Subgroup and restricted cubic spline (RCS) regression explored the serum folate concentration and elderly diastolic hypertension relationship. RESULTS: This study included 9,419 participants (4,734 females and 4,685 males) with a mean age of 70.0 ± 7.0 years. Among them, 360 were diagnosed with diastolic hypertension. In the fully adjusted model, there was a negative correlation between serum folate concentration and the prevalence of diastolic hypertension (OR 0.65; 95% CI: 0.52-0.82). When serum folate concentration levels were divided into quartiles (in µg/dL), the ORs for diastolic hypertension corresponding to Q2 (1.29-1.98), Q3 (1.99-3.08), and Q4 (3.09-5.56) levels compared to Q1 (0.18-1.28) were 1.41 (95% CI: 0.60-3.33), 0.48(95% CI: 0.20-1.16), and 0.35 (95% CI: 0.16-0.74), respectively, with a P for trend <.05. Restricted cubic spline plots showed a negative correlation between serum folate concentration and the prevalence of diastolic hypertension (non-linearity: p = .495). Subgroup analysis indicated that the negative correlation between serum folate concentration and the prevalence of diastolic hypertension was more significant in female participants (interaction p = .009). CONCLUSION: Higher serum folate concentration is associated with a lower prevalence of diastolic hypertension in the elderly.

What is the context?Diastolic hypertension, characterised by high blood pressure during the relaxation phase of the heartbeat.It significantly elevates the risk of cardiovascular diseases such as heart attacks and strokes.This study examines how serum folate levels relate to diastolic hypertension in the elderly, aiming to uncover correlations that inform future management strategies.What is new?This study investigated the relationship between serum folate concentration and the prevalence of diastolic hypertension in individuals aged over 60.Analysing data from multiple cycles of the National Health and Nutrition Examination Survey (NHANES), researchers found a noteworthy correlation between higher serum folate levels and a lower prevalence of diastolic hypertension.This association remained significant even after adjusting for various factors such as age, sex, and other health variables.What is the impact?The findings underscore the potential significance of folate intake in lowering the prevalence of diastolic hypertension among the elderly.It suggests avenues for further research into nutritional interventions targeting hypertension in this vulnerable population, potentially leading to more effective preventive measures and improved health outcomes.

Differential changes in end organ immune cells and inflammation in salt-sensitive hypertension: effects of increasing M2 macrophages.

Salt-sensitive hypertension (SSHTN) is associated with M1 macrophage polarization and inflammatory responses, leading to inflammation-associated lymphangiogenesis and functional impairment across multiple organs, including kidneys and gonads. However, it remains unclear whether promoting M2 macrophage polarization can alleviate the hypertension, inflammation, and end organ damage in mice with salt sensitive hypertension (SSHTN). Male and female mice were made hypertensive by administering nitro-L-arginine methyl ester hydrochloride (L-NAME; 0.5 mg/ml) for 2 weeks in the drinking water, followed by a 2-week interval without any treatments, and a subsequent high salt diet for 3 weeks (SSHTN). AVE0991 (AVE) was intraperitoneally administered concurrently with the high salt diet. Control mice were provided standard diet and tap water. AVE treatment significantly attenuated BP and inflammation in mice with SSHTN. Notably, AVE promoted M2 macrophage polarization, decreased pro-inflammatory immune cell populations, and improved function in renal and gonadal tissues of mice with SSHTN. Additionally, AVE decreased lymphangiogenesis in the kidneys and testes of male SSHTN mice and the ovaries of female SSHTN mice. These findings highlight the effectiveness of AVE in mitigating SSHTN-induced elevated BP, inflammation, and end organ damage by promoting M2 macrophage polarization and suppressing pro-inflammatory immune responses. Targeting macrophage polarization emerges as a promising therapeutic approach for alleviating inflammation and organ damage in SSHTN. Further studies are warranted to elucidate the precise mechanisms underlying AVE-mediated effects and to assess its clinical potential in managing SSHTN.
