Active clinical trials for "Peripheral Arterial Disease"

The 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).

Veterans 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.

A multicenter randomized, double blind placebo controlled trial to determine the efficacy of long-term, low dose warfarin in the secondary prevention of venous thromboembolism.

One 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.

To compare two gadolinium contrast agents in terms of global paired diagnostic preference (primary endpoint) for the assessment of contrast-enhanced MR Angiography of the carotid, renal/abdominal and peripheral arteries

After 6 weeks of maximal Ranolazine therapy, tissue hemoglobin desaturation kinetics will change compared to placebo in patients with chronic angina and peripheral arterial disease.

Primary objective: To evaluate whether 12 weeks of clopidogrel is superior to ticlopidine in terms of lower risk of the safety events of interests in patients with peripheral arterial disease (PAD) Secondary objectives: To compare the risk of bleeding adverse events, serious adverse events and overall safety of clopidogrel with ticlopidine To compare the risk of vascular events of clopidogrel with ticlopidine To document the long-term safety of clopidogrel for a total of 52 weeks To document the vascular events of clopidogrel for a total of 52 weeks

This is a feasibility pilot study to evaluate the impact of local delivery of Yamani-15/5 (combination of L-Lactic acid 15% and D-Gluconic acid 5%) on vascular calcification of lower extremities in patients with severe peripheral arterial disease (PAD) who were deemed to have unreconstructable arterial disease and who have already been scheduled to undergo limb amputation (below knee or above knee amputation).

Aim: To determine whether the lactate threshold during CPET is influenced by the presence of haemodynamically significant PAD. Assumption: Correction of haemodynamically significant PAD results in an increased LT, measured by CPET. Design: Prospective study Population: Thirty patients scheduled to undergo surgical or percutaneous treatment of iliofemoral arterial disease for intermittent claudication.

The purpose of the study is to assess the effect of blood flow to the heart when subjects are treated with ticagrelor (Brilinta) or clopidogrel (antiplatelet drugs that stop the blood from clumping together) in patients with Peripheral Artery Disease (PAD).
