Filter by:This trial is a 2 x 2 factorial design, double-blinded, randomized controlled trial to evaluate efficacy and safety of remote ischemic preconditioning and postconditioning in patient undergoing coronary angioplasty.
Ischemia reperfusion injury causes the release of free oxygen radicals. The selective alpha2-receptor agonist, dexmedetomidine, has an inhibitory effect on inflammatory responses during ischemic injury. The aim of this study is to evaluate the effect of dexmedetomidine on inflammatory responses during ischemia-reperfusion injury in skeletal muscle.
The model by which physicians measure the lack of blood flow in the vessels that supply blood to the heart muscle is called Fractional Flow Reserve (FFR). FFR is the measurement of the pressure across the vessels that supply blood to the heart. These are known as the coronary arteries. This study involves comparing two FFR wires, the St. Jude Medical Pressure Wire (PW) and the ACIST Navvus Microcatheter (MC) to check the accuracy of the devices. FFR allows real-time estimation of the effects of a narrowed vessel, whereas standard angiography can underestimate or overestimate narrowing, because it only visualizes contrast (the different areas of color) inside a vessel.
This study evaluates the clinical effectiveness of Magnetic Resonance(MR) perfusion imaging to qualitatively assess adequate distal perfusion after endovascular revascularization in Critical Limb Ischemia
The study aims to identify several factors that can accurately predict the incident of intestinal infraction in patients with mesenteric vascular occlusion or ischemia.
This is an exploratory, randomized, open-label, 2-arm, parallel-group study exploring the efficacy of rosuvastatin (20mg/day) in patients with acute ischemic stroke.
This study evaluates the outcomes of stroke patients treated for intravascular thrombectomy, using either a local anesthetic with sedation, or a general anesthetic. Historical data will be used for those treated with the local anesthetic, and prospective data will be used for those treated with the general anesthetic.
Critical limb ischaemia (CLI) is the most serious stage of peripheral occlusive arterial disease (POAD). Despite progress in the revascularization procedures, half these patients experience amputation or death after one year. One issue is to identify these subjects because aggressive treatment is necessary in those cases, while in others (ie leg ulcer in a patient with POAD but no rest lower limb ischaemia), revascularization will not be necessary. Then it would be useful to develop a simple score to help the physician to improve diagnosis of CLI.
The study is designed to assess the safety and efficacy of allogeneic human umbilical cord-derived mesenchymal stem cells (hUC-MSCs) with injectable collagen scaffold transplanted into patients with chronic ischemic cardiomyopathy.
This study will assess the feasibility of lower limb-ischemia induced Remote Ischemic Conditioning (RIC) in the perioperative period before, during, and after Orthotopic Liver Transplantation (OLT). Remote ischemic conditioning will consist of 3 cycles of 5 minutes of lower limb ischemia induced via a mid-thigh pneumatic tourniquet, followed by 5 minutes of reperfusion. Interventions will take place after anesthesia induction but before surgery, at the completion of the procedure, and on the mornings of post-operative days 1-4.
