Filter by:The specific aims of the project are as follows: To determine whether catheter-based revascularization procedures improve functional capacity and quality of life among patients with intermittent claudication. To investigate whether improvements in walking ability result in a less sedentary lifestyle and improvement of the cardiovascular risk profile.
The prevalence, incidence, and severity of atherosclerotic disease all markedly increase with age. Basic experimental and observational data demonstrate that aging magnifies the pathologic and clinical consequences of established risk factors and is the most potent individual risk factor for coronary atherosclerosis and for adverse outcomes following an ischemic event. These findings suggest that normal aging alters the vascular substrate so as to promote the development and progression of atherosclerosis. The age-associated changes in vascular structure and function include an increase in central vascular stiffness, intimal proliferation, and endothelial dysfunction. The major hypothesis is that the above alterations in vascular substrate (i.e. vascular age) are an important determinant of the age associated increased likelihood for the development and progression of coronary atherosclerotic disease. This program will non-invasively characterize vascular age and atherosclerotic burden in BLSA participants and individuals with successful aging, i.e. those with no or minimal evidence of coronary atherosclerotic disease, and those with premature, clinically evident coronary artery disease. It will repeat measures of vascular age and atherosclerotic burden three years after the first assessment. By examining the impact of vascular age on the initial extent and the progression of atherosclerotic burden over a two to three-year period, it will test the hypothesis that vascular age is an important determinant of the ageassociated increase in atherosclerotic disease....
Approximately 30 patients will be enrolled in this 12-week study designed to assess the effect of continuous subcutaneous Remodulin therapy on the outcome of infrainguinal bypass grafts in patients with critical limb ischemia (CLI). Portions of the study will be conducted in the hospital and on an out-patient basis. The study will be conducted at multiple centers.
The purpose of this study is to assess and compare the safety of continuous and daily subcutaneous Remodulin therapy in patients with critical limb ischemia (CLI) with no planned vascular interventional procedures; and to determine the effect of Remodulin on wound healing and treadmill walk distance.
Ecraprost in lipid emulsion is being developed for the treatment of Critical leg ischemia (CLI), which is the most severe form of peripheral arterial disease (PAD). This trial is designed to assess the efficacy and safety of the drug in the treatment of CLI.
This study will evaluate the effects of vitamin E supplementation in retarding the progression of common carotid artery intima-media thickening in African Americans.
