Hypertension is a global health challenge, especially in low-to-middle-income countries, where awareness and control are suboptimal. Despite available treatments, poor medication adherence hampers blood pressure control, leading to adverse outcomes and increased costs. In response, the GOI has initiated national action plans to address noncommunicable diseases, including hypertension. The study aimed to analyze patient retention rates in hypertension treatment across healthcare levels and understand providers' and patients' perspectives on control factors. Using a mixed-method concurrent design in a North Indian district, retrospective data collection covered hypertensive patients registered from January 2020 to July 2020, followed for a year (August 2020–July 2021). Quantitative data included socio-demographic characteristics and patient follow-up rates. Qualitative data comprised focus group discussions (FGD) and in-depth interviews (IDI) with healthcare providers (HCPs) and patients. Findings identified challenges in patient retention and medication adherence, notably among females and at higher-level healthcare facilities, leading to substantial loss of follow-up. Only 63% of hypertensive outpatients maintained controlled blood pressure in the past year. Male patients exhibited more consistent attendance than females. Despite sufficient HCP knowledge, patient retention was better at Health and Wellness Centers (HWCs) levels, while blood pressure control was poorer at higher facilities. Barriers such as medication side effects, pill burden, and limited healthcare access hindered hypertension control, highlighting the need for improved primary care services, including extended clinic hours and diagnostic facilities. Improving hypertension control requires addressing medication adherence and healthcare access barriers. Strengthening primary care services and implementing patient-centered interventions are crucial steps.

There are no nationwide surveys on antihypertensive drugs in China. In order to assess the current status of antihypertensive drug therapy in patients with hypertension and analyzed factors that may affect combination therapy, using convenience sampling, we recruited 305,624 patients with hypertension from the Chinese Cardiovascular Association Database-Hypertension Center between January 2019 and December 2021. Chi-squared test was performed to analyze the administered antihypertensive drug types and their combinations in different hospital settings. Logistic regression was used to assess the factors influencing combination therapy. We found around 33.1% of the participants had stage 2 and above hypertension, of which 67.9% were treated with combination therapy. In community or general hospitals, the most common monotherapy was calcium channel blockers (CCB), angiotensin-converting enzyme inhibitor/angiotensin II receptor inhibitor (ACEI/ARB) and diuretic were the main single-pill combinations (SPCs), and ACEI/ARB and CCB were the main free combination. From 2019 to 2021, the rates of combination therapy increased (58.8%–64.1%) with SPCs from 25.9% to 31.0% and free combination from 31.9% to 32.6%. Patients aged < 60 years, with stage 2 and above hypertension, with an education level of high school and above, visiting general hospitals, living in the eastern region of China, with hypertension risk factors and comorbidities, and without anxiety or depression were more likely to receive combination therapy (all P < .05). The combination therapy use rate increased yearly and the rate of SPCs rose obviously. Individual, hospital, and regional differences in patients with hypertension influenced combination therapy.

Fibromuscular dysplasia (FMD) is a disease of the musculature of arterial walls leading to stenoses, aneurysms, and dissections. The purpose of this report was to summarize the evidence for (1) one-time routine imaging from brain-to-pelvis and (2) lifelong antiplatelet therapy, for example, aspirin, for patients diagnosed with FMD as suggested by an international consensus report from 2019.

PubMed was systematically searched, and the evidence providing a basis for the current consensus points, as well as articles published since, were reviewed. In four registries evaluating patients with FMD, the prevalence of multivessel involvement, aneurysms, and dissections was reported to be 43.5%–66.3%, 21.6%–30.6%, and 5.6%–28.1%, respectively. Any antiplatelet drug was used in 72.9% of patients, and aspirin was prescribed in up to 70.2% of patients. Based on the high prevalence of vascular manifestations, their associated morbidity, and the potential for endovascular or surgical intervention, the suggestion of one-time brain-to-pelvis screening with computed tomography angiography or magnetic resonance angiography is well supported. Contrarily, the evidence to support the consensus statement of lifelong antiplatelet therapy to all patients in the absence of contraindications is more uncertain since a beneficial effect has not been demonstrated specifically in patients with fibromuscular dysplasia. Therefore, until the efficacy and safety of primary thromboprophylaxis have been demonstrated in this patient group specifically, it may be equally appropriate to only use antiplatelet agents in patients with a clear indication after individual evaluation according to risk factors for thrombotic and thromboembolic complications.

The relationship between the differential protective effect of salt substitute between hypertensive and normotensive individuals and the use of cardiovascular medications remains unclear. This study involved 4211 individuals with a history of stroke or hypertension who participated in the Salt Substitute and Stroke Study (SSaSS) from 120 villages in Shanxi Province. The aim of this study was to investigate the differences in major adverse cardiovascular events and blood pressure changes between the salt substitute and the regular salt group in the subgroups of participants taking different antihypertensive medications. Mixed models were employed and adjusted for the cluster effect (village) and potential confounding variables. During the average follow-up period of 4.66 years, a significantly protective effect of salt substitute on reducing the risk of cardiovascular events was observed in the participants who taking antihypertensive medications (rate ratio: 0.81, 95% CI: 0.68 to 0.95. p = 0.011), whereas no significant effect in participants not taking antihypertensive medications (rate ratio: 0.91, 95% CI: 0.62 to 1.32, p = 0.612). Significant effects to lower systolic blood pressure of the salt substitutes were observed in the participants who took different antihypertensive medications. This study emphasized that the use of salt substitutes might enhance the efficacy of anti-hypertensive medications in lowering blood pressure and reducing the risk of adverse cardiovascular events.

Left ventricular (LV) hypertrophy (LVH) is frequently observed in patients with hypertension (HTN). LV myocardial work (MW) has recently emerged as a non-invasive method to assess systolic myocardial deformation relative to afterload conditions. The authors investigated the characteristics of myocardial work with different degrees of LVH in HTN patients. From December 2020 to February 2024, 255 HTN patients and 26 healthy controls undergoing transthoracic echocardiography were included in the current study. Hypertension patients were divided into quintile groups based on left ventricular mass index (LVMI), for the first to fourth LVMI quantiles, global work index (GWI) and global constructive work (GCW) were higher compared to the control group, but the difference was not statistically significant. In the sixth LVMI quantile, GWI and GCW showed a significant decrease. The restricted cubic splines showed that both GWI and GCW exhibited an inverted U-shaped relationship with LVMI. A LVMI of >151.39 g/m² could accurately predict reduction both in GWI and GCW (Sensitivity: 0.78, Specificity: 0.89, AUC: 0.90, P < .001; Sensitivity: 0.81, Specificity: 0.92, AUC: 0.92, P < .001, respectively). As LVH progressed in HTN patients, both GWI and GCW initially demonstrated an increase, followed by a subsequent decrease. Myocardial work provides additional insights into assessment of cardiac function in HTN patients.

There is conflicting evidence in select mouse models and humans that suggest angiotensin-converting enzyme 2 expression is increased due to treatment with angiotensin converting enzyme inhibitors and angiotensin receptor blockers (ACEI/ARBs). Given the wide range of conditions that these medications treat, further evaluation is necessary to determine safety in the context of COVID-19. We sought to determine the association between use of ACEI/ARBs and COVID-19 severity in patients with essential hypertension. We included 714 patients with essential hypertension diagnosed with COVID-19 and admitted to University of Iowa Healthcare from March 1, 2020 to June 29, 2021. Severity of COVID-19 infection was assessed based on mortality, length of stay in hospital, intensive care unit admission, and use of supplemental oxygen, invasive ventilation, and vasopressors. Multivariable logistic and linear regression analyses were used for binary and continuous outcomes, respectively. Prior exposure to ACEI/ARBs before admission was significantly associated with lower mortality (OR: 0.454, p = .015), shorter length of stay in hospital (p < .001), and decreased adjusted odds of intensive care admission (OR: 0.719; p < .042). The present results suggest that patients with essential hypertension hospitalized with COVID-19 who had a prescription for ACEI/ARBs prior to admission exhibited less severe COVID-19 and lower in-hospital mortality.

Hypertension has become a major contributor to the morbidity and mortality of cardiovascular diseases worldwide. Despite the evidence of the anti-hypertensive effect of gastrodia-uncaria granules (GUG) in hypertensive patients, little is known about its potential therapeutic targets as well as the underlying mechanism. GUG components were sourced from TCMSP and HERB, with bioactive ingredients screened. Hypertension-related targets were gathered from DisGeNET, OMIM, GeneCards, CTD, and GEO. The STRING database constructed a protein–protein interaction network, visualized by Cytoscape 3.7.1. Core targets were analyzed via GO and KEGG using R package ClusterProfiler. Molecular docking with AutodockVina 1.2.2 revealed favorable binding affinities. In vivo studies on hypertensive mice and rats validated network pharmacology findings. GUG yielded 228 active ingredients and 1190 targets, intersecting with 373 hypertension-related genes. PPI network analysis identified five core genes: AKT1, TNF-α, GAPDH, IL-6, and ALB. Top enriched GO terms and KEGG pathways associated with the anti-hypertensive properties of GUG were documented. Molecular docking indicated stable binding of core components to targets. In vivo study showed that GUG could improve vascular relaxation, alleviate vascular remodeling, and lower blood pressure in hypertensive animal models possibly through inhibiting inflammatory factors such as AKT1, mTOR, and CCND1. Integrated network pharmacology and in vivo experiment showed that GUG may exert anti-hypertensive effects by inhibiting inflammation response, which provides some clues for understanding the effect and mechanisms of GUG in the treatment of hypertension.

In this pilot study, the authors investigated the preliminary effectiveness of the digital lifestyle intervention, actensio (mementor DE GmbH), in treating arterial hypertension. Adults with arterial hypertension were randomly assigned to an intervention group (actensio + standard care) or a control group (waiting list + standard care) in a 1:1 ratio. Primary and secondary endpoints were assessed at baseline (t0) and 3 months post-randomization (t1). The primary endpoint was average systolic blood pressure, measured at home for 1 week. Secondary endpoints included patient engagement (measured using the “patient activation measure”; PAM-13), average diastolic blood pressure, and heart rate. All endpoints were analyzed using ANCOVA models, following an intention-to-treat approach, while adjusting for baseline values. Missing data were estimated using multiple imputation models. A total of N = 102 participants (f = 59, age = 52.94 ± 9.01) were randomized to either the intervention (IG; N = 52) or the control group (CG; N = 50), of which N = 80 completed the blood pressure diary, and N = 81 the PAM-13 at t1. Between-group comparisons showed an average group difference in systolic blood pressure of −5.06 mm Hg (95% CI = −8.71 to −1.41, p = .013) between the intervention group (M = 137.37 ± 10.13) and the control group (M = 142.35 ± 11.23). Average group difference for patient engagement was 3.35 points with a trend towards statistical significance (95% CI = −018 to 6.89, p = .064), favoring the intervention group (M_IG = 79.38 ± 9.44 vs. M_CG = 75.45 ± 10.62). There were no group differences in diastolic blood pressure (−1.78 mm Hg; 95% CI = −4.50 to 0.95, p = .402) and heart rate (−0.684; 95% CI = −3.73 to 2.36, p = 0.683). The results of the present pilot study confirm the preliminary effectiveness of the digital lifestyle intervention, actensio, in reducing high blood pressure in patients with hypertension.

Telomere length is closely linked to biological aging, oxidative stress, and the development of cardiovascular diseases. This study aimed to assess the association between dietary selenium intake and telomere length in individuals with hypertension. Data on dietary selenium intake were captured through the National Health and Nutrition Examination Survey (NHANES) computer-assisted dietary interview system (CADI). Telomere length determination entailed selecting blood samples from all participants in the NHANES database. The analysis was performed using Analysis System software, with Empower stats utilized for data analysis. Results showed that there was a significant association between dietary selenium intake and telomere length in hypertension, particularly within the female group. In female hypertension cases, a 1 mcg increase in dietary selenium intake corresponded to a telomere length increase of 1.19 bp, even after adjusting for age, race, BMI, marital status, physical activity, energy intake, and stroke history. The relationship between dietary selenium intake and telomere length exhibited a linear pattern in female hypertension patients. This study identified a positive association between dietary selenium intake and telomere length in hypertension, particularly within the female group.

The coarctation of the aorta (CoA) combined with heart defects or cerebral artery aneurysms is more prevalent in clinical practice. However, cases of concurrent bilateral iliac artery dissection (IAD) are extremely rare and have not been reported. Here, we described a case with CoA combined with bilateral IAD. The patient, a 62-year-old male, presented with acute intermittent claudication accompanied by pain and aching in both lower limbs after walking. Following a thorough medical history inquiry and examination, the patient was diagnosed with acute bilateral IAD combined with CoA. The patient underwent endovascular treatment. Postoperatively, the aortic diameter recovered, and the bilateral IAD disappeared, yielding satisfactory therapeutic results. Conclusively, endovascular treatment of aortic coarctation combined with IAD is an effective therapeutic approach, enhancing patient survival and improving their quality of life.
