Vascular Disease clinical trials at UC Health
9 in progress, 7 open to eligible people

  • Effect of Changing Physiological Conditions on Myogenic Oscillations: Pilot Study

    open to eligible people ages 18 years and up

    Spontaneous myogenic oscillations will be studied under general anesthesia using finger photoplethysmography. This pilot study will explore potential physiological conditions that will effect the amplitude and/or frequency of myogenic oscillations.

  • Factors that Affect Outcomes in Cardiovascular Surgery

    “Physicians reviewing medical records to discover factors that affect outcomes in Cardiovascular Surgery”

    open to eligible people ages 18 years and up

    Identify factors that contribute to perioperative morbidity and mortality in patients undergoing cardiac surgery that involves cardiopulmonary bypass. Identify factors that affect perioperative morbidity and mortality in patients undergoing cardiac surgery.

  • Intima Versus Adventitia Drug Delivery to Elucidate Mechanisms of Restenosis: Magnetic Resonance Imaging

    open to eligible people ages 35 years and up

    This is a prospective, multicenter, randomized trial to determine the mechanisms of vascular healing. The study will evaluate subjects with peripheral artery disease (PAD) who require an endovascular intervention of the femoro-popliteal (SFA) artery to restore blood flow to the leg.

  • Long-term Telerehabilitation for Patients With Stroke

    open to eligible people ages 18 years and up

    The aim of the current protocol is to study 40 patients, each for 12 weeks, to address hypotheses related to the ability of a telerehabilitation system to (a) improve motor status and disability, (b) collect various forms of patient data from the home, (c) improve risk factor knowledge and control, and (d) assess patient compliance with home-based telerehabilitation. Patients who have returned to their home after stroke will be provided with a telehealth system and be asked to use it 6 days/week for 12 weeks, during which time subjects will use this system for daily rehabilitation therapy, assessments, and education--all on one platform.

  • Mechanisms of Early Recurrence in Intracranial Atherosclerotic Disease

    open to eligible people ages 30-99

    The objective of this study is to determine the mechanisms of stroke in patients with Intracranial Atherosclerotic Disease (IAD) by specifically evaluating limitations of antegrade flow through the stenotic artery, distal tissue perfusion to the affected territory, and artery-to-artery embolism. The hypothesis is that non-invasive imaging biomarkers that stratify stroke risk and distinguish mechanisms of IAD. This prospective multicenter study will enroll 175 patients with recently symptomatic high-grade IAD. Patients will be studied within 21 days of the index event (allowing appropriate time to arrange for diverse imaging modalities), with the following advanced neuroimaging techniques to elucidate mechanisms of recurrent ischemia: - Quantitative magnetic resonance imaging (QMRA) to assess volumetric flow rate through the stenotic artery. - Magnetic resonance perfusion weighted imaging (PWI-MRI) to determine distal tissue perfusion. - Vasomotor reactivity by Transcranial Doppler using the breath-holding technique (BHI-TCD) to assess compensatory flow characteristics to the territory distal to the affected artery; - Transcranial Doppler with embolic signal monitoring to evaluate artery-to-artery embolism that reflects plaque instability. Patients will receive standardized medical management and its effectiveness on blood pressure, lipid, and glycemic control will be monitored. The primary outcome is recurrent stroke in the territory of the stenotic artery during a 1-year follow-up period; secondary outcomes are: a) new asymptomatic ischemic lesions on MRI in the distribution of the stenotic artery at 6-8 weeks, and b) transient ischemic attack (TIA) in the distribution of the stenotic artery during a 1-year follow-up period. Patients will be recruited at various sites that will be trained and certified on the imaging techniques employed. Raw imaging data will be interpreted centrally.

  • Pediatric Pulmonary Hypertension Network (PPHNet) Informatics Registry

    open to eligible people ages up to 21 years

    Patients are being asked to be in this research study because medical researchers hope that by gathering information about a large number of children with pulmonary hypertension over time, their understanding of the disease process will increase and lead to better treatment. Investigators believe that pulmonary hypertension in children is different than pulmonary hypertension in adults and this study will help us understand those differences.

  • THE OMEGA-SPM-DOSE and OMEGA-SPM-PAD: Specialized Pro-Resolving Mediators in Patients With Peripheral Artery Disease

    open to all eligible people

    The purpose of this study is to understand the effects of fish oil supplement (containing parts of omega-3 fatty acids) on inflammation. The investigators are aiming to identify which dose of the fish oil supplement is the most effective. The name of the fish oil supplement is "SPM Emulsion."

  • Real-World Registry Assessing the Clinical Use of the Lutonix 035 Drug Coated Balloon Catheter

    Sorry, in progress, not accepting new patients

    The objective of this patient registry is to assess the clinical use of the Lutonix 035 DCB PTA Catheter in a heterogeneous patient population in a real world and on-label clinical application.

    at UCSD

  • Safety and Efficacy Study of Autologous Concentrated Bone Marrow Aspirate (cBMA) for Critical Limb Ischemia (CLI)

    Sorry, in progress, not accepting new patients

    This trial will evaluate the safety and efficacy of concentrated bone marrow aspirate (cBMA) to prevent or delay major amputation and/or death in subjects with critical limb ischemia (CLI) due to severe peripheral arterial disease (PAD).
