Filter by:The purpose of this gene therapy study is to evaluate the safety and efficacy of intramuscular gene transfer using Vascular Endothelial Growth Factor (VEGF) or placebo in patients with moderate to high-risk Critical Limb Ischemia (a condition in which there is poor blood circulation in the leg). This trial will assess whether VEGF improves rest pain and/or heals ulcers in the legs of patients with peripheral artery disease (blockages in leg arteries.) VEGF is DNA, or genetic material that will be injected into the leg muscles on three separate occasions, each 2 weeks apart. Once the DNA is in the leg, it directs the cells of the artery wall to increase its production of VEGF, which has been shown to cause new blood vessels to grow. This experimental therapy is designed to grow new blood vessels around blockages in the leg arteries. The total length of participation in this study is approximately 1 year and will require approximately 8 clinic visits within that year. Following enrollment in the study, testing may be done for cancer screening, blood work, physical exams, vascular testing and eye exams. There is no charge for any testing or office visits required by the study. This study has been approved by the Food and Drug Administration (FDA).
Evaluate for difference in outcome between hospital admission versus discharge after recent TIA, and evaluate feasibility of a larger study.
The purpose of this study is to evaluate the efficacy and safety of intramyocardial injections of CLBS14 in patients with refractory chronic myocardial ischemia.
The purpose of this study is to assess the safety and feasibility of HBOC-201 in increasing adequate wound healing in patients with severe peripheral vascular disease who are undergoing lower limb amputation. The hypothesis is that HBOC-201 will pass through the partially occluded lesions in the peripheral arteries in the lower extremity and promote the wound healing process by delivering oxygen to the oxygen deprived tissues. This will reduce the incidence of lower limb wound complications at 60 days post-surgery and may reduce the incidence of a second amputation.
The aim of this study is to improve the detection of heart attack in people who come to a hospital emergency room (ER) with cardiac symptoms. We are testing a novel technology that calculates the heart's electrical activity at points all around the upper body torso and develops a map showing areas indicating heart attack. Our hypothesis is that this new body mapping technique will be better than the standard electrocardiogram (ECG) in detecting heart attack.
The lack of blood flow to the small intestine causes mesenteric ischemia. Using a Superconducting QUantum Interference Device (SQUID) which measures the magnetic field of the small intestine, we are hoping to identify abnormalities without surgical intervention.
Many people in the UK have ischaemic heart disease. Insufficient blood supply to the heart muscle means that it functions inefficiently, and leads to symptoms of shortness of breath, chest pain and excess fluid in the body. Recently it has been shown that cells from the inside of bone are able to produce many different cell types. We are investigating a new treatment in which a patient's bone marrow cells are taken, and injected into the heart in an attempt to produce new blood vessels and heart muscle cells. This may lead to a new treatment for ischaemic heart disease.
The purpose of this study is to compare 2 different cold storage solutions, used to preserve donor lungs for lung transplantation, and their effect on cytokine activation related to ischemic reperfusion injury. Primary endpoint is 30 day survival.
The purpose of this study is to compare two types of exercise stress testing to find the best method for detecting heart disease in women.
The main objective is to observe the effects of erythropoietin administration on different blood markers of ischaemic cardiac lesions induced by cardiopulmonary bypass.
