Active clinical trials for "Ischemia"

PAD is caused by an increased flow resistance in atherosclerotic ischemic limbs. The investigators hypothesize that reducing blood viscosity (through controlled phlebotomy), thereby increasing the deformability of red blood cells, should reduce the flow resistance and improve tissue perfusion leading to improved clinical function and a reduction in symptoms. Preliminary data demonstrates that phlebotomy causes a measurable change in blood viscosity as measured by the home-made rheologic method. To evaluate the effectiveness of changes in blood viscosity, obtained through controlled phlebotomy, as a therapy to improve functional status associated with atherosclerotic ischemic limbs in pre-amputation patients.

The main objective of this study is to document that the thrombectomy catheter (Rev-01) is effective and safe when used for revascularization in subjects with acute ischemic stroke within 8 hours of symptom onset who are ineligible for treatment with IV t-PA, or in whom treatment with IV t-PA has been ineffective.

The aim of this study is to evaluate the safety of Ginkgolides Meglumine Injection in the treatment of ischemic stroke with Syndrome of Intermingled Phlegm and Blood Stasis.

This study will evaluate the safety and efficacy of intracoronary injection of mesenchymal stem cells (MSCs) to repair heart function in patients with myocardial ischemia.

The study objectives are to assess any changes in visual acuity and visual field observed following the administration of RPh201 during an overall treatment period of at least 13 consecutive weeks with an option to extended the treatment phase to another 13 weeks (26 weeks total), and at the follow-up visit at 3 month after end of treatment in patients with optic nerve neuropathy.

Patient presenting with upper GI bleed in ILBS (Institute of Liver and Biliary Sciences) emergency admitted to ICU (Intensive Care Unit) or shifted from ward to ICU (Intensive Care Unit) in view of upper GI bleed randomized to two groups GROUP A : 110 Patients will receive standard care + NAC infusion for 72 hours GROUP B : 110 Patients will receive standard care only NAC will be given at following rate : Initial loading of 150 mg/kg/hr over 1 hour Followed by 12.5mg/kg/hr for 4 hrs Then continuous infusion of 6.25 mg/kg for the remaining 67 hrs

Prospective, multi-center, randomized, controlled, open, blinded-endpoint trial with a sequential design. The randomization employs a 1:1 ratio of mechanical thrombectomy with stentriever and/or Thromboaspiration versus medical management alone. Randomization will be done under a minimization process using age, baseline NIHSS, use of IV tpa, vessel occlusion site and hospital. To evaluate the hypothesis that mechanical thrombectomy is superior to medical management alone in achieving more favorable outcomes in the distribution of the modified Rankin Scale scores at 90 days in subjects presenting with acute large vessel ischemic stroke <8 hours from symptom onset. Subjects are either ineligible for IV alteplase or have received IV alteplase therapy without recanalization. Sample size is projected to be 690 patients for a difference in treatment effect of 10%.

The goal of this study is to determine if pre-operative placement of the continuous peripheral nerve block by an anesthesiologist using ultrasound technology is more effective than a continuous peripheral nerve block placed during the surgery by a surgeon for patients undergoing a limb amputation

Despite advances in the treatment of heart attacks the complications and death rates from failure of the heart to pump properly after treatment remain high. A heart attack occurs when one or more of the arteries that supply blood to the heart become blocked, causing the heart to be starved of oxygen and nutrients. This results in damage to the heart and so the the heart pumps less well. The main treatment for a heart attack is balloon treatment to open the blocked artery (called primary angioplasty). Whilst re-opening the artery is essential and allows blood to flow to the area of the heart starved of oxygen, this process also causes damage itself (called reperfusion injury) and increases the size of the heart attack further. Currently there are no treatments available that reduce this reperfusion injury. The investigators and others have shown that a substance called sodium nitrite reduces reperfusion injury in experimental models of a heart attack. The aim of this research is to perform a trial to investigate whether during a heart attack, an infusion of sodium nitrite into the damaged artery protects against reperfusion injury and reduces heart attack size in patients.

The aim of the presented clinical trial is to evaluate a hypothesis, that BMAC prepared from bone marrow aspirate and injected intramuscularly into ischemic areas of the lower extremity in patients with diabetes mellitus type II., intraarterially into the defect of the limb or with an intravenous application only, has a greater potential to improve the perfusion in the ischemic limbs than standard treatment of NO-CLI. Another aim of the study is to find out differences among three different therapeutic types of BMAC application, to define their effectiveness and safety and to compare the impact of different means of application to the speed of healing of the limb defects and the improvement of perfusion parameters.
