NCT ID: NCT06439498 Active, not recruiting - Clinical trials for Orthostatic Hypotension

Frequency of Orthostatic Hypotension in Patients Who Underwent Colonoscopy

Start date: May 1, 2024
Phase:
Study type: Observational

Patients who will undergo colonoscopy accompanied by sedoanalgesia will be admitted at Aksaray Training and Research Hospital Gastroenterology Clinic between May and July 2024. Orthostatic hypotension will be evaluated after patients meet the discharge criteria in the postoperative recovery unit.

NCT ID: NCT06348589 Not yet recruiting - Clinical trials for Chronic Kidney Disease Requiring Chronic Dialysis

Orthostatic Hypotension and Blood Pressure Variability in Persons Undergoing Hemodialysis

Start date: April 2024
Phase:
Study type: Observational

High blood pressure is a risk factor for end-stage renal disease and is common in patients undergoing maintenance hemodialysis. Intradialytic hypotension is associated with an adverse prognosis. More knowledge is needed to identify patients at high risk for intradialytic hypotension and dialysis-associated hypotensive episodes. The aim of this observational single-center pilot study is to evaluate whether point-of-care ultrasound measurements may predict intradialytic hypotension and orthostatic blood pressure falls, in patients with chronic kidney disease who undergo maintenance hemodialysis.

NCT ID: NCT06188663 Not yet recruiting - Clinical trials for Orthostatic Hypotension

SalT Supplementation in Older Adults With Orthostatic Intolerance Disorders

STOOD
Start date: June 2024
Phase: Phase 2
Study type: Interventional

Background Orthostatic hypotension (OH) is a common cause of falls, and key source of morbidity and mortality due to injury (e.g. hip fracture). Current guidelines recommend increasing salt intake in patients with symptomatic orthostatic hypotension. However, the evidence underpinning this recommendation is poor, based primarily on small trials with very short-term follow-up (< 6 weeks). Clinical Equipoise (Overall) High salt intake might improve quality of life and reduce the risk of falls, but might also increase the risk of cardiovascular disease, in patients with OH. Specific Objective of Current Application (Aim) To determine feasibility (recruitment, retention and adherence) of conducting a randomized controlled trial evaluating high salt intake in older adults with symptomatic orthostatic hypotension. To determine preliminary estimates of the effect of high salt intake on disease-specific quality of life, orthostatic blood pressure (BP) parameters, and cardiac blood biomarkers. Design: Phase IIa, parallel, double-blind, randomised controlled, single centre clinical trial of 12 month follow-up duration. Population: Older adults (≥65 years of age) with an objective diagnosis of symptomatic orthostatic hypotension Intervention: The intervention will be 5g/day of salt supplementation in the form of encapsulated sodium chloride. Outcome measures: Primary outcome (Feasibility) recruitment and retention rates, adherence with intervention and study protocol, completeness of follow-up. Secondary Outcome (Efficacy): i) clinical: change in Orthostatic Hypotension Questionnaire score, modification/addition of OH pharmacotherapy, and falls events, ii) physiological measures of orthostasis: change in difference between supine and nadir systolic BP, standing BP at 1 minute, 24 hour mean BP measured by 24 hour ambulatory BP monitor, iii) cardiovascular biomarkers. Clinical Importance: A recommendation for long-term increases in salt intake may have adverse cardiovascular consequences, which necessitates the identification of the optimal range of salt intake associated with greatest reduction in falls risk and lowest cardiovascular risk. Our study will provide preliminary evidence of treatment effect and assess feasibility, to inform a definitive trial.

NCT ID: NCT06039410 Recruiting - Clinical trials for Orthostatic Hypotension

A Novel Device for the Treatment of Postural Hypotension - a Signal of Effectiveness Study.

Start date: December 15, 2023
Phase: N/A
Study type: Interventional

The goal of this clinical trial is to test a novel medical device (ISO-101) in patients diagnosied with orthostatic hypotension. The main question[s] it aims to answer are: - to determine whether the ISO-101 device demonstrates a signal of efficacy in people with OH and whether it is worthy of further clinical evaluation. - Assess the safety and performance of the ISO-101 device in patients with orthostatic hypotension. Participants will use the device under controlled conditions and have the following parameters measured before and after standing up: - blood pressure - markers of peripheal vascular resistence - sympathetic nervous system activity measure before and after standing up

NCT ID: NCT05982652 Active, not recruiting - Clinical trials for Spinal Cord Injuries

NCT ID: NCT05960448 Recruiting - Clinical trials for Orthostatic Hypotension

Autonomic Effects of Spinal Cord Stimulation in Spinal Cord Injury

Start date: July 30, 2023
Phase: N/A
Study type: Interventional

The goal of this interventional crossover study is to determine the effects of transcutaneous spinal cord stimulation (TSCS) on the ability to perform moderate exercise and regulate core body temperature in the chronic spinal cord injury community. The main questions it aims to answer are: - What are the effects of active TSCS targeted for BP control on exercise endurance time and HR recovery during submaximal arm cycle ergometry (ACE) as compared to sham TSCS in participants with chronic, cervical SCI? - What are the effects of active TSCS on Tcore responses to cool ambient exposure and on subjective reporting of thermal comfort and thermal sensitivity as compared to sham TSCS. Participants will receive sham and active stimulation while using an arm bicycle or while in a cold room. Participants are free to participate in either the exercise phase, the cold room phase, or both phases of this study. Please note that there no expected long term benefits of this study.

NCT ID: NCT05908760 Recruiting - Autonomic Failure Clinical Trials

CO2 Rebreathing in nOH: A Proof-of-Concept Pilot Study

Start date: May 5, 2024
Phase: N/A
Study type: Interventional

Neurogenic orthostatic hypotension (nOH) is a chronic condition associated with increased cardiovascular risk and reduced quality of life. On standing, patients with nOH experience a large reduction in blood pressure (BP; at least ≥20/10mmHg, but often much more), which is often accompanied by debilitating symptoms and syncope. A previous study (unpublished) showed that hypercapnia significantly increases standing BP in patients with nOH. Human bodies naturally produce and exhale CO2. Rebreathe devices offer a simple, cost-effective technology to increase arterial CO2. In brief, rebreathe devices work by capturing expired CO2, which is then re-inhaled. The net effect is a transient increase in CO2. A CO2 rebreathing device may offer a novel hemodynamic therapy for patients with nOH. This is a pilot, proof-of-concept study to evaluate a CO2 rebreather to improve blood pressure and orthostatic tolerance in patients with nOH. The hypothesis is that a rebreather will increase CO2 sufficiently enough to improve BP in patients with nOH. Male and female patients (n=28) will be asked to complete two randomized 70° head-up tilt (HUT) tests breathing either room air or using a CO2 rebreather. Hemodynamics (BP, heart rate, stroke volume, brain blood flow) and orthostatic symptoms will be assessed throughout. Breath-by-breath data will include O2, CO2, respiration rate and tidal volume. The primary outcome measure will be the magnitude of the BP response (ΔBP = HUT - Supine) during Room Air vs. Hypercapnia. The primary outcome will be compared between room air and hypercapnia using a paired t-test.
