Renal sympathetic denervation (RDN) was considered an effective alternative for patients whose blood pressure (BP) is not optimally controlled. The RDN works mainly by selectively disabling the nerves around the renal arteries and reducing blood pressure increase. However, despite the early success showed in the SYMPLICITY HTN-2 trial, the SYMPLICITY HTN-3 trial failed to demonstrate a significant BP reduction when compared to sham-control. incomplete disabling might result in inadequate denervation and were cited as some of the contributors to the nil result in the SYMPLICITY HTN-3 . The new generation of the Symplicity Spyral catheter aims to address some of these issues by altering the configuration of the catheter to allow better apposition to the renal arterial wall and increasing the numbers of electrodes to faciiitate more thorough ablations. However, the adequacy of sympathetic denervation with this new catheter can not be easily assessed at the time of the procedure as there is no simple physiological or biochemical feedbacks that can be monitored during the procedure. Blood pressure response by renal nerve simulation (RNS) during RDN procedure using the previous generation of the Symplicity Flex catheter have been reported to be potential parameter to assess the efficacy during the procedure and predict the BP response 6 months after RDN. The feasibility of RNS guided RDN procedure using the new generation of Symplicity Spyral catheter has not been reported. We therefore aim to explore the feasibility of RNS guided RDN with Symplicity Spyral Radiofrequency Catheter in patient with resistant hypertension.
Objective:The possible association between hypertension and periodontitis and the effect of hypertension on periodontal treatment were investigated by evaluating salivary and gingival crevicular fluid (GCF) interleukin (IL)-6 and C reactive protein (CRP) levels. Methods:Forty two healthy individuals without any previously diagnosed systemic disease [10 periodontally healthy (control) and 10 periodontitis (CP)] and subjects with hypertension [13 periodontally healthy (HP) and 9 with periodontitis (CP + HP)] participated in the study. GCF and saliva samples were obtained at baseline and four weeks after Phase I periodontal treatment. Biochemical parameters were analyzed using ELISA. Results:Before the periodontal treatment, significantly higher GCF IL-6 and CRP levels were detected in CP+HP and CP groups compared to HP and control groups (p<0.01). Salivary CRP level in CP+HP group was found to be higher than the control group (p<0.05). Statistically significant gingival and plaque index measurements (p<0.01) might suggest a possible effect of hypertension on periodontal status. Periodontal treatment significantly improved the clinical indices, however biochemical parameters did not change after the treatment. Conclusion:the association of hypertension with periodontitis through local salivary and GCF mediators might be possible in disease process.
This aim of the study is to evaluate the effect of nebulized nitroglycerin on echocardiographic (biventricular function, pulmonary artery pressure, PDA and PFO shunting and tissue doppler imaging) and clinical parameters (Oxygen saturation index, heart rate, blood pressure, mean airway pressure, ventilation setting) in patients with PPHN.
This study is intended to assess the ability of AZD3427 to reduce pulmonary vascular resistance (PVR) after 24 weeks of treatment in participants with heart failure (HF) and pulmonary hypertension (PH) Group 2
The objective of this study is to test the feasibility of using behavioral economic interventions (gamification with social incentives) to increase physical activity after hospital discharge to reduce incident mobility disability among older adults.
Diet interventions (e.g., low-energy diets) are recommended as a treatment for obesity, obese patients with osteoarthritis, hypertension (HTN), and type 2 diabetes (T2D). However, these diets are not a common part of the care plan partly because it is not financially feasible to discuss and offer them in medical offices reimbursed with the standard fee-for-service model. New reimbursement models, like value-based care (VBC), exist. It may be financially feasible to offer diet interventions, like premade and delivered meal plans to address these medical issues. This pilot study will help determine if a more extensive prospective study of the clinical effects of a delivered, premade low-energy diet (LED) on clinical markers of these disorders, as well as future cost-benefit analyses. Methods: A case series of five obese subjects with knee osteoarthritis, HTN, and T2D receive a LED for 12 weeks. The primary outcome is the change in the Numeric Pain Rating Scale (NPRS) at 12 weeks. Secondary outcome measures include the change in other patient-reported outcomes between the start and end of the study, changes in weight, changes in measures of HTN and T2D, and the proportion of subjects using non-protocol interventions. Hypothesis: Subjects randomized to the diet intervention will demonstrate a clinically significant improvement in NRPS score (2 points), a clinically significant weight reduction (15%), a 50% improvement in systolic and diastolic blood pressure, 1.0% reduction in Hemoglobin A1C levels (HgA1C), and lower utilization of non-protocol treatments at 12 weeks.
The aim of this study is to compare standard education with VR augmented education in patients with arterial hypertension
Study name: Screening, Diagnosis and Treatment of Obstructive Sleep Apnea Syndrome in Hypertensive Patients in China: A Prospective National Multi-center Registry. Rationale: Obstructive sleep apnoea syndrome (OSAS) is a common secondary cause of hypertension and significantly correlated with the risk of cardiovascular and cerebrovascular diseases. However, continuous positive airway pressure (CPAP) only shows modest blood pressure lowering effect, although it is effective in the relieve of daytime sleepiness and other symptoms of OSAS. One of the possible reasons for the low antihypertensive efficacy might be the low adherence to CPAP therapy. Nonetheless, few studies systematically investigated CPAP adherence with regard to its prediction and clinical relevance for cardiovascular protection and prevention. Objective: 1) To evaluate short- and long-term CPAP adherence in patients with hypertension and obstructive sleep apnea syndrome; 2) To investigate the predictors of short- and long-term CPAP adherence; 3) To explore the correlation between the CPAP adherence and blood pressure, target organ damage and the incidence of cardiovascular and cerebrovascular events. Study design: Prospective, multi-center, observational study. Study population: Patients with hypertension who are suspected to have obstructive sleep apnea syndrome due to snoring, daytime sleepiness and other related symptoms are considered eligible and should meet the following criterias: 1) Agree to participate in the study and sign the informed consent; 2) At least 18 years old; 3) STOP-Bang questionnaire, score ≥3 points; 4) Complete polysomnography in hospital; 5) Currently on CPAP therapy. Follow up: 3, 6 and 12 months after registry. Sample size estimation: At least 633 patients. Timeline: Start of subjects' enrollment: Jan 2023; End of subjects' enrollment: December 2026; End of study: December 2026. Organization: The Centre for Epidemiological Studies and Clinical Trials, Ruijin Hospital, Shanghai, China.
Due to health and wealth disparities, no demographic group is more at risk than African American women for the double jeopardy of stress from caregiving for persons living with dementia (PLWD) and stress associated with hypertension (HTN). This double jeopardy puts those they care for in jeopardy as well: Reduced quality of life and longevity, disability, cognitive decline, and stroke associated with HTN1 impede caregiving activities and resultant health and well-being for persons living with Alzheimer's disease and related dementias (ADRD). Although successful multi-component interventions have addressed ADRD caregiver stress (REACH II) and the Savvy Caregiver program, to our knowledge there are no interventions that target the complexity of chronic caregiving stress and HTN self-care for African American women caregivers of persons living with ADRD. This project will test two interventions for their effectiveness in improving outcomes for the target group: Mindfulness in Motion (MIM) and the Dietary Approaches to Stop Hypertension (DASH). MIM includes mindful awareness and movement from a seated position, breathing exercises, healthy sleep, and guided mindfulness meditation. The DASH component will be tailored for Black Americans. It uses a critical thinking approach that involves problem solving, participant-centered goal setting, health coaching, reflection, and development of self-efficacy (confidence) to promote physical activity and healthy eating. Solid empirical evidence demonstrates its effectiveness in reducing blood pressure among mixed-race samples.
