The obesity pandemic, with its associated comorbidities of hypertension and diabetes, constitutes a global public health issue. Importantly, there is an increasing prevalence of aldosterone excess related to obesity and resultant poor health outcomes. Nevertheless, the association between aldosterone and obesity still needs to be clarified. In this review, the authors discuss the role of white adipose tissue in linking obesity, aldosterone excess, and hypertension. The consequences of aldosterone excess in obesity are presented as genomic, non-genomic, and non-epithelial effects. Moreover, the authors emphasize the value of interference with aldosterone pathophysiology (as with mineralocorticoid antagonists) in obesity, thus reducing the adverse clinical impact of aldosterone in myocardial infarction, heart failure, kidney dysfunction, and associated mortality.
This analysis of real-world data examines the efficacy, safety, and long-term outcomes of renal denervation in hypertensive patients for up to 10 years. Sixty-five consecutive patients underwent renal denervation (RDN) (single operator) for uncontrolled resistant hypertension. Efficacy was defined as the interindividual change of office (OBPM) and ambulatory blood pressure monitoring (ABPM) at 1, 6, 12 months, 2–4 and 5–10 years after RDN. Medication changes, renal function, and device generation disparities were analyzed. Of these patients, 42 received RDN with a first-generation device, while 23 underwent the procedure with a second-generation device. Baseline demographics included a predominantly male cohort (57.6%) with an average age of 60.3 years. The mean number of medications at baseline was 4.3. OBPM at baseline was 169.0/87.4 mmHg, and ABPM at baseline was 153.4/88.4 mmHg. Post-procedure, significant reductions in systolic blood pressure (SBP) were observed in both OBPM and ABPM at 1 month (OBPM 147.9/82.8 mmHg; ABPM 141.3/83.0 mmHg [SBP, p < 0.001]), sustained up to 10 years (OBPM 153.1/84.3 mmHg; ABPM 138/80.1 mmHg [SBP, p < 0.001]). After 1 year around half of patients had a controlled OBPM and 24 h ABPM < 135/85 mmHg, which was associated with a higher number of ablation spots (31.5±14.8 vs. 15.5 ± 6.5, p = 0.002) and occurred more often when treated with a second-generation device (2 [12.5%] vs. 7 [77.8%], p = 0.002). Renal function displayed a minor physiological decline over 5–10 years. No major complication occurred. Renal denervation demonstrated sustained significant reductions in systolic OBPM and ABPM up to 10 years post-procedure. Controlled blood pressure at 1 year was associated with a higher number of mean ablated spots and the use of a second-generation device. The procedure exhibited a favorable safety profile, indicating its viability in managing hypertension without significant renal function compromise.
To evaluate the long-term efficacy and safety of transfemoral access (TFA) versus upper extremity access (UEA) for renal denervation (RDN) based on vascular morphology. This study retrospectively enrolled patients with resistant hypertension who underwent RDN treatment via TFA and UEA (brachial, radial, and ulnar artery) at the Fuwai Hospital between February 2012 and November 2019. Follow-up was conducted at 6 months, 1 year, and 3 years after RDN, and the last visit was June 2023. A total of 85 patients were enrolled, 58 (68.2%) of them were treated via TFA, and 27 patients (31.8%) via UEA. The fluoroscopy time was less in the TFA group (12.2 ± 5.7 min vs. 15.2 ± 7.2 min; p = 0.038). The procedure time (TFA group: 40.8 ± 14.9 min vs. UEA group: 38.6 ± 11.6 min; p = 0.506), contrast volume (TFA group: 78.2 ± 25.9 mL vs. UEA group: 91.9 ± 39.7 mL; p = 0.061) were similar between two groups, without procedure-related complications. Fifty-eight participants completed the last visit with a 3–12 year of follow-up (9.5 ± 1.3 years). Compared with baseline, there were no significant differences in the change of office systolic blood pressure (−12.6 ± 21.6 mmHg vs. −13.1 ± 22.8 mmHg; p = 0.933), 24-h mean systolic blood pressure (−11.9 ± 14.2 mmHg vs. −11.3 ± 15.3 mmHg; p = 0.899), the number of antihypertensive drugs, and renal function between two groups. There were three adverse events in the TFA group (3 of 58 patients, 5.2%) versus one (1 of 27 patients, 3.7%) in the UEA group, without a significant difference between the two groups. The study showed RDN via UEA was feasible using a special-designed catheter, particularly in patients with illegal vascular morphology via TFA.
Long-term visit-to-visit blood pressure (BP) variability is linked to various diseases, but its impact on cerebral small vessel disease (cSVD) burden, and its features remains uncertain. We analyzed 1284 participants from the Kailuan cohort (2006-2022). Visit-to-visit systolic BP (SBP), diastolic BP (DBP), and pulse pressure (PP) variability were categorized into tertiles (low, middle, high). Magnetic resonance imaging identified white matter hyperintensities (WMH), lacunae of presumed vascular origin (LA), cerebral microbleeds (CMBs), and visible perivascular spaces (PVS). Total cSVD burden was classified as none (0), mild (1), moderate (2), or severe (3-4) based on the presence of these features. Logistic regression estimated odds ratios (ORs) and 95% confidence intervals (CIs). High SBP variability was associated with moderate cSVD burden (OR = 1.89, 95% CI: 1.09-3.29) and PVS (OR = 1.62, 95% CI: 1.10-2.39). High DBP variability was associated with LA (OR = 1.74, 95% CI: 1.06-2.84). High PP variability showed a significant risk for severe cSVD burden (OR = 2.49, 95% CI: 1.34-4.63). These associations were modified by age and hypertension status. Among young adults (age < 60 years), high PP variability was associated with severe cSVD burden (OR = 3.33, 95% CI: 1.31-8.44), LA (OR = 3.02, 95% CI: 1.31-6.93), and PVS (OR = 1.86, 95% CI: 1.20-2.88). The risk effects of SBP and PP variability on cSVD burden were significant only in participants with hypertension. High long-term visit-to-visit BP variability (BPV), particularly in combination with hypertension, is a significant risk factor for total cSVD. Special attention should be given to PP variability in younger adults.
Renovascular hypertension (RVH) is a primary cause of secondary hypertension, primarily driven by the activation of the renin–angiotensin–aldosterone system activation. Recently, growing studies suggested accessory renal artery (ARA) might also contribute to RVH. However, the treatment of ARA-related hypertension and whether to take interventional treatment lack consensus. Herein, we report two cases of ARA-related hypertension in our hospital. Imaging studies of both patients showed ARA stenosis. One patient had ARA occlusion well-compensated through tortuous collateral branches, achieving normal blood pressure by medical treatment alone. The other patient had ARA stenosis coexisted with main renal artery stenosis, and revascularization of both arteries led to a significant postoperative reduction in blood pressure. A literature review was conducted to summarize overall treatment strategies for ARA-related hypertension and clarify the relationship between ARA and hypertension. Recent research supported an association between ARA and hypertension. While medical therapy remains the first-line treatment for ARA-related hypertension, interventional procedures should be considered for patients whose blood pressure remains uncontrolled despite conservative management.
Literature on the association between the cardiometabolic index (CMI) and chronic kidney disease (CKD) risk is limited, especially in hypertensive populations. The objective of the present investigation was to assess the relationship between the CMI and CKD risk in a hypertensive population. The current cross-sectional study included a total of 13 717 individuals with hypertension. The calculation of the CMI was based on the waist-to-height ratio and the triglyceride-to-high-density lipoprotein cholesterol ratio. The definition of CKD was based on an estimated glomerular filtration rate (eGFR) of less than 60 mL/min/1.73 m2. The prevalence of CKD was found to be 4.24% in younger adults (aged < 65 years) and 14.93% in the elderly (aged ≥ 65 years). The results of the multivariate regression analysis indicated that in the elderly group, the CMI was positively associated with CKD risk (odd ratio [OR] 1.29; 95% confidence interval [CI]: 1.14, 1.46), while no significant relationship was observed in the younger group (OR 1.04, 95% CI: 0.85, 1.27). Furthermore, subgroup analyses did not identify any potential factors that could modify the relationship between the CMI and CKD risk (all p for interaction > 0.05). Among adults with hypertension, there was an independent and positive correlation between the CMI and CKD risk in the elderly, whereas such a correlation was not observed in younger adults.

Radiofrequency renal denervation (RF RDN) is a novel therapy for uncontrolled hypertension. In the recent sham-controlled SPYRAL HTN-ON MED study, office-based systolic blood pressure (oSBP) and nighttime BP were reduced significantly. This study examined the cost-effectiveness of RF RDN in the context of the Japanese healthcare system based on this latest clinical evidence.
Clinical events, costs, and quality-adjusted life-years (QALYs) were projected using a decision-analytic Markov model adjusted to Japanese incidence data. Risk reduction in clinical events from changes in oSBP was calculated based on a published meta-regression of 47 trials of intentional hypertension treatment. Demographics and results from the SPYRAL HTN-ON MED trial (oSBP effect size −4.9 mmHg vs. sham) were utilized in the base case analysis. Additional scenarios were explored including the potential added benefit of improved night-time control. Costs were sourced from claims data and published literature. The incremental cost-effectiveness ratio (ICER) was evaluated against a cost-effectiveness threshold of ¥5 000 000 per QALY gained.
RF RDN was projected to reduce clinical events (10-year relative risks: 0.80 for stroke, 0.88 for myocardial infarction, and 0.75 for heart failure). Over lifetime, RF RDN added 0.36 QALYs at the incremental cost of ¥923 723, resulting in an ICER of ¥2 565 236 per QALY gained. Under the assumption of added night-time benefit, the ICER decreased to ¥2 155 895 per QALY. Cost-effectiveness findings were robust across all tested scenarios.
The findings of this model-based analysis suggest that RF RDN can provide meaningful clinical event reductions and is a cost-effective treatment option in the Japanese healthcare system.
The management of hypertension and diabetes poses significant challenges to China's healthcare system, necessitating seamless patient progression through screening, diagnosis, management, and control. Utilizing the care cascade model, this study aims to systematically identify patient drop-offs and devise strategies to address healthcare delivery bottlenecks for hypertension and diabetes in rural China. This study consists of three phases. In Phase 1, qualitative interviews are conducted to explore healthcare experiences and identify determinants across the care cascade. Phase 2 involves systematically assessing barriers identified in Phase 1 and collaborating with local stakeholders using intervention mapping and co-design to generate interventions and implementation strategies. Phase 3 is a cluster randomized controlled trial involving 48 villages, randomly assigned in a 1:1 ratio, to compare changes in hypertension and diabetes care. Intervention villages will implement interventions developed in Phase 2 for 1 year, while control villages will continue with usual care. Primary outcomes include between-group differences in achieving blood pressure and glycemic targets, along with service and implementation outcomes. This study aims to identify the stage with the largest patient retention gap in the care cascade and develop intervention strategies through participatory co-design with practitioners, emphasizing feasible, low-cost approaches. The pragmatic cluster RCT will assess strategy effectiveness, offering valuable insights for practical interventions to enhance hypertension and diabetes care in rural settings, potentially shaping impactful programs and improving healthcare outcomes.
