NCT05297708
This will be a prospective observational study. The population would be pediatric patients 6 years to \<19 years of age who were referred for elevated blood pressure to investigate if home blood pressure (HBP) can determine blood pressure phenotype (normotensive, hypertensive, masked hypertension, white coat hypertension) as accurately as ambulatory blood pressure monitor (ABPM) in childhood and adolescence.
NCT05121337
GoFresh is a randomized trial, testing the effects of a home-delivered DASH-patterned grocery intervention on blood pressure in Black adults, residing in Boston area urban food deserts.
NCT07413614
ACHIEVE aims to determine whether exercise can be a safe and effective non-drug approach to improve blood pressure control in patients with primary open-angle glaucoma (POAG). Although exercise is a promising and potentially well-accepted therapy, its use in clinical care is limited because the safety and effectiveness of different exercise types (aerobic, isometric, moderate, or high intensity) and timing (morning versus evening) have not been systematically studied in people with POAG and elevated blood pressure. This study will evaluate the safety and short-term effects of different exercise modalities and timings on 24-hour ambulatory blood pressure and blood pressure variability in patients with POAG and elevated blood pressure. It is hypothesized that: * Each exercise session will lead to a temporary reduction in blood pressure (post-exercise hypotension). * The greatest and longest-lasting reduction will occur after high-intensity aerobic exercise performed in the morning. It is also expected that all exercise types and timings will be safe for participants.
NCT03816462
This is an ongoing, prospective cohort study of children and young adults who are evaluated in the Reversing the Negative Effects of Weight on the Heart (ReNEW) Clinic at Johns Hopkins University. Demographic and clinical data of patients who agree to participate are obtained via chart review and entered into a longitudinal clinic registry.
NCT07048509
In this study, the investigators will evaluate acute changes in vascular function measures after moderate-intensity continuous and high-intensity interval exercise in healthy and prehypertensive individuals. Participants will be subjected to three separate visits: control condition (30 min rest), moderate-intensity continuous exercise, and high-intensity interval exercise. The investigators will measure aerobic capacity using a cardiopulmonary exercise test (CPET) using indirect gas-exchange to derive subsequent exercise intensity and maximal oxygen uptake. The investigators will evaluate different measures of vascular function (Pulse-wave velocity, Flow-mediated slowing, microvascular function) before and after each condition. The study will involve two groups of participants: healthy individuals and prehypertensive individuals. The investigators aim to establish the reliability and validity of less-established methods of vascular function assessment (flow-mediated slowing and microvascular function) against established measures (pulse-wave velocity). The acute response of vascular function to different exercise intensities has not yet been thoroughly researched using the aforementioned measures in individuals with similar characteristics to the proposed study cohort.
NCT06982365
This study is a pragmatic, randomized, double-blind, placebo-controlled trial aimed at evaluating the potential health benefits of Enovita® (standardized grape seed extract) supplementation in adults with elevated blood pressure or Stage 1 hypertension. The primary objective is to assess the impact of Enovita® on systolic and diastolic blood pressure over 8 weeks. Secondary outcomes include changes in mood, emotional well-being, perceived stress, lipid profile, and systemic inflammation. The study will also monitor the safety and tolerability of Enovita®.
NCT05397535
The aim of this study is to evaluate the effects of Baduanjin on blood pressure in individuals with high normal blood pressure (SBP 130-139 mmHg, and/or DBP 85-89 mmHg), as well as on glucose and lipid metabolism, quality of life, psychology, exercise, immune inflammation, endothelial function, and arterial stiffness.
NCT06843577
The study will be a multi-center, randomized clinical trial to evaluate the safety and efficacy of using the Zona Plus handgrip therapy device compared to the use of an auditory relaxation therapy for treatment of high blood pressure and hypertension in subjects who are not currently taking antihypertensive medications. Half of the study subjects will also be randomized to record blood pressure at home throughout the study.
NCT05955040
This is a randomized controlled trial comparing the outcomes of treatment and non-treatment of elevated blood pressures in early pregnancy.
NCT03626363
This study evaluates the impact of mindfulness-based stress reduction (MBSR) on sympathetic nerve activity and arterial stiffness. The investigator's central hypothesis is that MBSR will reduce sympathetic activity and arterial stiffness.
NCT06669715
In this study, investigators will use the IFT 30-15 test, a six-minute walking test, and a treadmill test to assess the participants' cardiorespiratory fitness. For the treadmill cardiopulmonary exercise test (CPET), we will measure indirect gas exchange using a CPET device (K5). Maximum heart rate (HRmax) will be measured with a Polar heart rate monitor (model H10). The six-minute walking test will follow standardized procedures, and the treadmill test will follow a protocol of gradually increasing speed each minute. The study will involve two groups of participants: healthy individuals and pre-hypertensive individuals. While the IFT 30-15 test has been validated on a diverse range of athletes and physically active individuals, it has not yet been validated in individuals with similar characteristics to our participants (BMI \> 30 and limited cardiovascular function). Additionally, a variety of hemodynamic measures and other physical function measures such as sit-to-stand and push-ups will be assessed for all participants.
NCT06629337
It was hypothesized that aerobic exercise with blood flow restriction (BFR) induced post exercise hypotension (PEH), and the reduction in blood pressure (BP) was due to peripheral vasodilation via the histamine receptors. Ten male participants participated in this study. The participants were randomly assigned to walk for 10 minutes at 6.4 k/m, 0% grade with or without BFR after taking histamine receptor blockade. Following exercise, BP was measured at 10 min interval for 60 minutes. Heart rate (HR), stroke volume (SV), cardiac output (CO), mean arterial pressure (MAP), and total peripheral resistance (TPR) were evaluated.
NCT04766424
The goal of this study is to test the efficacy of a behavioral sleep extension intervention on sleep duration, cardio-metabolic disease risk factors, and health behaviors among adults with elevated blood pressure/hypertension and short sleep duration.
NCT06033417
The purpose of this study is to evaluate the effect of an 8-week walking program on blood pressure in inactive older adults with respiratory impairment, a condition where lung function is sub-optimal for a person's age. Older adults with respiratory impairment have greater risks of death by cardiovascular disease (CVD) compared to those without respiratory impairment, and this may be partly driven by higher resting blood pressure. One way to lower blood pressure is to increase the number of daily steps achieved throughout the course of everyday life ('lifestyle steps'), and previous research shows that an additional 3,000 lifestyle steps/day is effective for achieving this. However, whether an increase in daily lifestyle steps is effective for reducing blood pressure in senior-community dwelling older adults with respiratory impairment is unknown. Understanding how increasing daily steps impacts blood pressure in this understudied population is important for informing future strategies for tackling cardiovascular disease risk in those with lung dysfunction.
NCT05928676
Conversion of dietary nitrates to nitric oxide (NO) is a non-canonical pathway that plays an important role in NO biology, particulalry under pathological conditions. Nitrate supplementation has been shown to help control mild hypertension. Recent studies have suggested that another gaseous transmitter, hydrogen sulfide, also influences NO biosynthesis and metabolism. This open-label clinical trial will evalute the effect of Vascanox® HP, a proprietary formulation that combines dietary sources of nitric oxide and hydrogen sulfide, on nitric oxide bioavailability and on blood pressure in subjects experiencing elevated blood pressure. Participants will supplement with Vascanox® HP for four weeks. Blood pressure will be measured at baseline, two weeks, and fours weeks. Salivary nitric oxide will be assessed prior to and two, six, and 24 hours after dosing on the first day of the study and prior to and two hours after dosing at subsequent study visits. Participants will also self-monitor their saliva nitric oxide levels and blood pressure daily for 4 weeks. Changes in study outcomes over time will be evaluated via analysis of variance (ANOVA) and paired t-tests.
NCT05370625
The main objective of the study will be to compare the efficacy of a 2.65 g/day dose of TOTUM-854 versus placebo in decreasing SBP in subjects with high-normal blood pressure and Grade I hypertension following 12 weeks of daily intake.
NCT03993184
This study will examine the effects of a 12 week hot yoga intervention on vascular health in adults between the ages of 20 and 65. The investigators are seeking individuals with slightly elevated blood pressure and stage I hypertension who are not currently taking blood pressure medications or exercising regularly. Participants will receive 12 weeks of free yoga for their participation.
NCT04298944
The investigators will aim to determine the association of mood disorders (MDO) with preclinical and clinical cardiovascular (CVD) risk factors among children. The investigators will also aim to identify traditional and non traditional predictors of CVD risk among children with MDO.
NCT05266885
Cardiovascular disease is the most prevalent cause of morbidity and mortality in diabetic patients. Hypertension has been confirmed as a major risk factor for cardiovascular disease, which is frequently associated with diabetes mellitus. Therefore, the detection and management of elevated blood pressure (BP) is a critical component of the comprehensive clinical management of diabetics. Since the rates of hypertension in diabetics are lacking in Afghanistan, this study aimed to evaluate the prevalence of elevated blood pressure in type-2 diabetic patients.
NCT02513823
This pilot study will examine the effectiveness of vitamin D supplementation on reducing blood pressure and improving endothelial function. Premenopausal African American women will be recruited. Participants will be instructed to record food intake for three days to estimate usual dietary intake at baseline and at the 10th week. At the baseline clinic visit a 10 week supply of vitamin D3 supplements (2,000 IU/day; Nature Made ®) will be given to participants and log sheets provided to record supplement intake. To answer the primary research questions, within subjects repeated measures analysis of variance (ANOVA) tests will be conducted to test if any differences in blood pressure, serum 25(OH)D concentrations, and RHI are statistically different after 10 weeks of supplementation with 2,000 IU/d of vitamin D. Exploratory multivariate linear regression models will be constructed to determine relationships between vitamin D status and vascular function parameters (blood pressure, RHI) before and after adjustment for age and BMI.
