Blood Pressure Clinical Trials

The purpose of our study is to understand the extent to which the blood vessels are affected by glucose and fat (lipids) in lean healthy adults and if these changes in the blood vessels contribute to the development of high blood pressure. Read Less

The purpose of this study is to examine the hypothesize that 4 weeks of sympathetic nerve activity (SNA) inhibition (oral clonidine) will cause a significant reduction in circulating blood concentrations and endothelial cell expression of inflammatory markers (e.g., TNF-α, IL-6). Our study is a prospective study using a randomized, double-blinded design to test 4 weeks of SNA blockade (oral clonidine) compared with a BP-lowering control condition (diuretic, hydrochlorothiazide) or a placebo.

In this research study we want to learn more about using non-invasive tools as a way to predict whether or not a child under general anesthesia will require and respond to fluid administration. It is important for an anesthesiologist to know if a child would respond to fluid administration so that they can provide the optimal intervention for low blood pressure and avoid unnecessary treatment.

The purpose of this Phase 1 research study is to answer two questions: (1) How frequent should periods of prolonged sedentary time be interrupted? and (2) What is the appropriate duration or length of time of these breaks in sedentary time? To address these questions, this project will conduct a state-of-the-art adaptive dose finding study under controlled laboratory conditions to determine the minimally effective dose (the smallest dose) that yields cardiometabolic benefit for two separate sedentary break elements (frequency and duration). Study findings will ultimately determine how often and for how long people should break up periods of prolonged sedentary time to transiently improve established cardiovascular risk factors; key foundational information critical to the success of future long-term trials and ultimately public health guidelines. Primary Aim: To determine the minimally effective dose combination(s) of frequency and duration needed to provide cardiometabolic benefit during an 8-hour experimentation period. Specifically, the study will determine: 1a. For each fixed duration, the minimum sedentary break frequency (e.g., every 30 min, 60 min, 120 min) that demonstrates a reduction in systolic BP, diastolic BP, or glucose compared with a sedentary control condition. 1b. For each fixed frequency, the minimum sedentary break duration (e.g., activity breaks of 1 min, 5 min, 10 min) that demonstrates a reduction in systolic BP, diastolic BP, or glucose compared with a sedentary control. Secondary Aim: It is also critical to public health strategy to assess the acceptability/feasibility of various sedentary break doses as too high a dose will yield poor uptake. To address this need, the maximally tolerated dose (the highest dose that does not cause undue physical/psychological distress) for frequency and duration of sedentary breaks will also be determined via assessment of 4 constructs: physical exhaustion/fatigue, affect (e.g., mood, emotion), tolerability (e.g., completion of dose protocol), and safety (e.g., hypoglycemia). Maximally tolerated dose will be defined as the highest dose where \<20% of participants exhibit an adverse outcome. Read Less

This study aims to validate a proprietary cuffless blood pressure algorithm using measurements from a multi-modal chest-worn medical device, the Perin Health Patch (PHP). Read Less

The treatments will be: 1) norepinephrine or phenylephrine infusion to maintain intraoperative MAP ≥85 mmHg (tight pressure management); or, 2) routine intraoperative blood pressure management (routine pressure management). Read Less

80 Beats Medical introduces the VicorderCS, the next generation of our Vicorder technology designed to manage hypertension and cardiovascular risks. This advanced diagnostic equipment offers non-invasive collection and computation of a plethora of cardiovascular markers. It is faster, easier to use, and more portable than its predecessor, with enhanced connectivity options for extended marker collection and analysis. These markers enable early diagnosis of cardiovascular disease, ensuring positive patient outcomes. With a strong foundation in numerous published clinical studies, the VicorderCS enhances data collection and analysis capabilities, empowering the research community in developing new drugs and therapeutics. This validation study is purposed to evaluate one of the physiological parameters that is measured by the VicorderCS system, which is Non-invasive Blood Pressure (NIBP) via the common oscillometric cuff-based method.

People who experience repeated bouts of circadian misalignment, such as shift workers, are at higher risk of cardiovascular disease (CVD) and Type 2 diabetes (T2D) compared to daytime workers. However, the mechanism(s) by which shift work and associated circadian misalignment increase CVD and T2D risk are unknown. This project will examine whether elevated plasma lipids are a mechanism by which circadian misalignment impairs vascular function, insulin sensitivity, glucose homeostasis and muscle lipid accumulation, which could be targeted to prevent and treat cardiometabolic disease in people who chronically experience circadian misalignment, which includes more than 20% of the US workforce.

Automated blood pressure cuff measurements taken by an "oscillometric device" is the standard in numerous medical settings today. Studies show that oscillometric devices using algorithms are more accurate and consistent than devices using other non-invasive measuring techniques, especially in critical cases. SureBP algorithm estimates BP during cuff inflation; the second, StepBP algorithm does so during deflation. The purpose of this study is to test the algorithms contained in the ModPG3 on Neonate and Infants subjects to determine if they meet the requirements of ISO 81060-2:2018/Amd 1:2020 Non-invasive sphygmomanometers - Part 2: Clinical investigation of intermittent automated measurement type Read Less

The purpose of this study in patients undergoing routine care epidural spinal cord stimulation (SCS) is to determine 1) whether SCS reduces arterial blood pressure (BP) in patients which chronic low back pain and hypertension, 2) whether higher baseline BP (i.e., hypertension) predicts reductions in pain following SCS, and finally 3) whether different SCS waveforms elicits stimulus-evoked compound action potentials (ECAPs) in spinal cord and at the cortex (electroencephalography, and magnetoenchphalography).
