Filter by: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).
To evaluate potentially modifiable lifestyle predictors of venous thromboembolism and their joint associations with biochemical and genetic determinants.
In the VA, we are achieving progress in decreasing amputation rates through early identification and multidisciplinary treatment of patients at risk for limb loss. Despite these accomplishments, however, clinical outcomes post-amputation, especially for PVD patients, have changed little because of patients' poor cardiovascular condition complicated by the injurious consequences of imposed inactivity begun in the preoperative period and continuing through convalescence. If not aggressively managed throughout all phases of recovery, these problems quickly render patients, already at risk, incapable of the rigors of rehabilitation as well as lead to reamputation, rehabilitation failure, and secondary complications. In our research, we are trying to transform this clinical scenario by applying what has succeeded in cardiac rehabilitation to services provided to amputees. In a series of studies, we are studying how to incorporate secondary CV risk factor modification and aggressive exercise interventions into conventional amputation rehabilitation through a program that we have named Healthy Heart Amputation Rehabilitation Therapy (Healthy H.A.R.T.). Our goal is to better: 1) increase aerobic capacity and promote rehabilitation achievements and quality of life, and 2) prevent postoperative complications and curtail further peripheral vascular deterioration through interventions found successful in cardiac rehabilitation. The basic assumption of this study will be that cardiovascular status and, thus, aerobic capacity is a most critical factor for rehabilitation success.
To investigate associations between hemostatic and inflammatory blood factors and progression of lower extremity arterial ischemia and cardiovascular events in men and women with and without lower extremity peripheral arterial disease.
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.
This study will determine if a highly standardized herbal extract of the leaves of the Ginkgo Biloba tree will benefit patients who have pain on walking due to narrowing of the arteries of the legs.
This is a working registry of a longitudinal cohort of Hispanics, Native Americans, and non-Hispanic whites (as controls) for tracking of vascular disease endpoints. Blood samples collected for ongoing pilot projects as well as specimen banking. Pilot studies are observational and involve risk measures for stroke, atherosclerosis, and vascular inflammatory responses. Questionnaires on demographics, risk factors, and vascular disease history are performed. No interventions proposed as yet.
The purpose of this study is to learn more about stroke and obtain information that may serve as the basis for future investigations. It will 1) establish a registry of patients with cerebrovascular disease (stroke); 2) characterize the natural history of acute stroke and transient ischemic attacks (TIA)-an interruption of blood flow to the brain that causes stroke symptoms for a short period of time); and 3) evaluate the data to generate ideas for future studies. Patients 18 years of age or older with suspected acute stroke or TIA may be eligible for this study. Subjects will be recruited from patients who present with stroke at the emergency department of Suburban Hospital in Bethesda, Maryland. The study will gather data collected from diagnostic and laboratory tests the patient undergoes as part of standard medical care, including findings of medical and neurological examinations and other tests. In addition, studies will be done for research purposes only to gather data about stroke and TIA. These may include the following: - Blood and urine tests not more than 2 tablespoons of blood will be drawn for various tests. - Electrocardiogram (EKG) (heart tracing)-electrodes placed on the chest wall detect the heartbeat and heart rhythm. - Computed tomography (CT) scan of the head-specialized X-rays are used to obtain images of the brain. - Magnetic resonance imaging (MRI) of the brain-a strong magnetic field and radio waves are used to produce images that provide information about the brain tissue and blood vessels. - Transcranial Doppler (TCD)-sound waves are used to image the arteries of the brain and neck. - Echocardiogram-sound waves are used to image the heart and evaluate heart function. Patients may be asked to return to Suburban Hospital for follow-up testing in 1, 3, and/or 12 months, when some of these tests may be repeated to assess changes over time
To conduct several studies on the epidemiology of venous disease.
In the first phase, to establish the relationship of progression of peripheral vascular disease (PVD) to plasma homocysteine. In the second phase, to conduct a randomized, controlled trial of folic acid treatment of plasma homocysteine in peripheral vascular disease.
