Active clinical trials for "Vascular Diseases"

After the participant meets all inclusion and exclusion criteria, they will be randomized equally to either the Resistance Training group (RT) or Aerobic Training group (AT). Both groups will participate in an 8 week initial control period, followed by 8 weeks of supervised exercise training, followed by 8 weeks of deconditioning. All participants will undergo the same assessments and procedures one time prior to the initial 8 week control period, and at each of the three periods. Assessments include: blood draws; arterial stiffness testing; ultrasounds of the brachial artery to measure flow-mediated dilation (FMD); gluteal adipose tissue biopsies; exercise testing to determine VO2 max; body composition analysis via DEXA scans; ambulatory blood pressure measurement; diet analysis via food journals; medical history questionnaires; urine analysis for pregnancy; and activity monitoring via accelerometer. Total participation will be 24-26 weeks.

The purpose of this study is to evaluate whether intramuscular injections of NL003 into the calf is safe and effective in the treatment of critical limb ischemia

A prospective randomized trial designed to compare the efficacy and safety of spot stent system versus self-expanding peripheral stent system in the endovascular treatment of femoropopliteal arterial stenotic disease.

Multicentre Study of nomacopan in Paediatric Haematopoietic Stem-Cell Transplant Associated Thrombotic Microangiopathy

The goal of this multicenter, multi-national, multi-arm, multi-stage, randomized controlled trial, is to determine the added benefit of hyperbaric oxygen treatment (HBOT) in patients with diabetic foot ulcers and peripheral vascular disease. The main question is: - What is the difference is the major amputation rate between the study arms? Participants will be randomized to 20, 30 or 40 sessions of HBOT or a control group.

Polypoidal choroidal vasculopathy (PCV), a subtype of neovascular age-related macular degeneration (NV AMD), is an important cause of central visual loss, especially among Asian and African descendants. PCV is characterized by the presence of hyperfluorescent polypoidal lesions, with or without branching vascular network, identified on indocyanine green angiography (ICGA), currently the gold standard for PCV diagnosis. In addition to visual improvement from baseline, polypoidal regression or complete disappearance of polypoidal lesions on ICGA has been considered an important treatment outcome in large PCV trials including the PLANET1 and EVEREST II2 studies. Rate of polypoidal regression following intravitreous aflibercept monotherapy was 33% in the PLANET study1 year 2 and ranged between 55% to 78% in other Asian cohorts.3-4 Recently, our previous investigation5 on the timing of polypoidal regression following a fixed-dosing aflibercept monotherapy (3 initial monthly injections, then q 8 weeks until 1 year) in 40 Thai PCV eyes suggested that, among 22 eyes (55%) with polypoidal regression at 1 year, a majority of them showed complete polypoidal regression before 6 months (median duration of complete regression: 3 months (IQR, 2 months to 6 months). However, due to the fixed-dosing regimen used in previous study, there are limited data on how often polypoidal lesions remain regressed on ICGA when the treatment is deferred in eyes with polypoidal regression, nor what changes might be seen subsequently on OCT when treatment is deferred in this situation. Therefore, this study aims to determine the changes seen on OCT subsequent to complete regression of polypoidal lesions on ICGA in PCV eyes following intravitreous aflibercept treatment. Results from this study may provide some insights on longer-term PCV management

The objective of this study is to determine if patients with lower extremity wounds in rural communities who undergo specialty referral through telemedicine have expedited care compared to patients who are treated through standard in person referral.

This is a single site, single-blinded parallel randomized control trial that investigates a multi-level intervention to improve postpartum blood pressure in women with hypertensive disorder pregnancy. The investigators will recruit women diagnosed with a hypertensive disorder of pregnancy, identified between 3rd trimester and 2 weeks post-delivery. The investigators will randomize participants to receive usual care home blood pressure monitoring for 6 weeks versus an intervention of usual care + blood pressure and weight monitoring + a doula trained in heart health. This trial will be conducted in partnership with a local community-based organization, Healthy Start Inc.

Supervised exercise therapy (SET), consisting of treadmill exercise conducted three times weekly at a center while supervised by healthcare personnel, is first line therapy for people disabled by lower extremity peripheral artery disease (PAD). However, travelling three times/week to a center for SET is burdensome. Compared to SET, home-based exercise is more accessible and less burdensome. Yet, evidence-based guidelines recommend SET over home-based exercise for PAD. Walking exercise is first line therapy to improve walking distance for PAD, but it does not eliminate ischemic leg symptoms in most people with PAD. The investigators' work and that of others showed that nitrate-rich beetroot juice, which increases plasma nitrite, limb perfusion, and skeletal muscle function, significantly improved exercise tolerance and reduced non-response to exercise in people with and without PAD. The investigators will use a 2 x 2 factorial design to address two major barriers to achieving benefits from exercise therapy for PAD: First, guideline recommendations for supervised exercise therapy (SET) as first line therapy for PAD. Second, the inability of exercise therapy to eliminate PAD-related disability in most people with PAD. Participants will be randomized to one of four groups for 12 weeks: Supervised treadmill exercise + nitrate rich beetroot juice; supervised treadmill exercise + placebo, home-based walking exercise + nitrate rich beetroot juice, home-based walking exercise + placebo.

The primary purpose of this clinical trial is to test the feasibility of implementing a perioperative guided meditation program for patients undergoing peripheral vascular interventions that are performed under procedural sedation and analgesia.
