Prevention of Autogenous Vein Graft Failure in Peripheral Artery Bypass Procedures
Peripheral Vascular DiseasesArterial Occlusive Diseases4 moreThe purpose of this study is to determine the efficacy of graft pretreatment with the E2F decoy, CGT003, as compared to placebo, on the occurrence of graft failure among patients who receive autogenous vein grafts to treat chronic critical limb ischemia; on the occurrence of clinically significant graft stenosis (more than or equal to 70%); and on the incidence of critical limb ischemia (e.g., gangrene, non-healing ischemic ulcers or ischemic rest pain).
Does the Reduction of Total Body Iron Storage (TBIS) Alter Mortality in a Population of Patients...
AtherosclerosisIntermittent Claudication1 moreVeterans Affairs Cooperative Study #410, The Iron and Atherosclerosis Trial, FeAST, a 24-hospital prospective randomized single-blinded clinical trial of graded iron reduction was conducted between May 1, 1999 and April 30, 2005, and has now been completed. A total of 1,277 primarily male participants with peripheral arterial disease were entered. The primary outcome was all cause mortality and the secondary outcome combined death plus non-fatal myocardial infarction (MI) and stroke.
Oral Calcium in Pregnant Women With Hypertension
Cardiovascular DiseasesHeart Diseases4 moreTo determine of providing calcium supplementation to women with pre-existing hypertension reduces the level of blood pressure, requirement for antihypertensive drugs, and incidence of pre-eclampsia.
Prevention of Recurrent Venous Thromboembolism (PREVENT)
Cardiovascular DiseasesHeart Diseases4 moreA multicenter randomized, double blind placebo controlled trial to determine the efficacy of long-term, low dose warfarin in the secondary prevention of venous thromboembolism.
Improving Access to Control of Diseases for Women
Cardio-vascular DiseaseStroke Cancer3 moreThe aim of this study is to evaluate the feasibility and acceptability of the model of delivering CHW-driven home-based comprehensive NCD control services aimed to prevent premature deaths from cardio-vascular diseases, stroke and breast, cervix and oral cancers in the hard-to-reach women.
Assessing Response to Inhaled Prostacyclin With Hyperpolarized Xe MRI
Pulmonary Vascular DiseaseThis study seeks to deploy several forms of 129Xe MRI contrast as well as emerging conventional proton MRI techniques for imaging lung structure and perfusion. Specifically, the 129Xe MRI scans will provide 3D images of ventilation and gas exchange, and spectroscopic indices will be evaluated too test gas exchange dynamics with high temporal resolution. The conventional 1H MRi scans will include a free-breathing ultra-short echo time scan that provides images similar to that of a CT scan. This will be done pre, immediately post, and 2-4 hours post inhaled prostacyclin therapy.

Idiopathic Polypoidal Choroidal VasculopathyTo asses the safety of intravitreal Zimura™ (complement factor C5 inhibitor) administered in combination with Eylea® in treatment experienced subjects with idiopathic polypoidal choroidal vasculopathy
A New Approach in Laser Surgery Using the Regenerative Solution in Children Diagnosed With Vascular...
Vascular DiseasesVascular Malformation4 moreLaser treatment (LT) is the first-line treatment for Vascular Pathology. However even when LT is based on the selective photothermolysis it causes the first-degree burns. While being typically benign by affecting only the epidermis, or outer layer of skin, the burn site is remaining red, dry, and very painful. As Haemoblock contains nanoparticles of silver and is known for both bactericidal and bacteriostatic effects, it likely decreases the potential for infection postoperatively. Furthermore, after fibrin replaces the superficial structure "Hemoblock-albumin", the polyacrylate matrix is plasmolyzed which initiates the cascade of signals required for the tissue regeneration processes. Objective of the study was to examine the effect of the Regenerative Solution "Hemoblock" in lowering postoperative complications in children diagnosed with Vascular Pathology undergoing a laser surgery if delivered with transdermal patches.
Acute Probiotic Supplementation and Endothelial Function
Coronary Artery DiseaseHypertension3 moreOne in every two deaths in the United States is caused by cardiovascular disease. Despite strong mechanistic links established between a diet rich in lipids and the pathogenesis of cardiovascular disease, therapeutic advances have focused on reduction in either ingestion or synthesis of cholesterol, and reduction in dietary trans and saturated fatty acids and triglycerides. Even in the setting of aggressive high potency statin therapy and global cardiovascular risk reduction efforts, most clinical trials reveal a significant residual cardiovascular risk with, at best, only 30% reduction in major adverse cardiovascular events. There exists a significant unmet clinical need for identifying novel therapies for the prevention and treatment of cardiovascular disease. This requires identification of additional contributory processes to cardiovascular disease pathogenesis, so that mechanism-based interventions may be developed. Endothelial dysfunction is a pathological state in which there is systemic inflammation of vascular endothelium with consequent expression of pro-vasoconstrictive mediators, thrombotic and atherogenic tendencies. Endothelial dysfunction precedes the development of atherosclerosis and portends an increased risk of future adverse cardiovascular events. Endothelial dysfunction, therefore, can serve as a "barometer" of future cardiovascular risk. Measurement of Flow-mediated dilation ( FMD) is widely accepted as a method to assess vascular endothelial function.
A Safety and Efficacy Study of NAC in Patients With TA-TMA
Thrombotic MicroangiopathiesHematologic DiseasesHSCT associated thrombotic microangiopathy(TA-TMA) is a heterogeneous, fatal disorder seen within 100 days post-transplant and presents with thrombocytopenia, hemolysis, acute renal failure, mental status changes and involvement of other organs. N-Acetylcysteine (NAC) is a small, simple molecule that began as a generic drug almost 40 years ago. It has since been approved by the FDA for many indications. The investigators conducted an prospective clinical trial to evaluate the safety and efficiency of NAC in patients with TA-TMA.
