Active clinical trials for "Peripheral Arterial Disease"

To examine the epidemiology of renal disease and its relationship to cardiovascular disease.

To test the hypothesis that increased risk of coronary heart disease, stroke, peripheral vascular disease, and cancer is related to diets high in saturated fat, animal protein, and hydrogenated vegetable oil, and low in polyunsaturated fat, fiber, vitamins A, C, and E, calcium, selenium, and chromium.

The Rio Study is a randomized, double blinded German- Swiss- Austria multi-centre trial on the efficacy and safety of ReoPro together with interventional recanalization of TASC D lesions in the SFA and popliteal artery.

This study is intended to help establish standard procedures for use of FFR in the peripheral arterial system and to evaluate the correlation of post-procedural FFR values and clinical outcomes in Superficial Femoral artery (SFA) interventions in subjects ages 18 to 79 with PAD.

Near-infrared spectroscopy can be used to determine the relative oxygen saturation in tissues up to 2cm below the skin. It has been investigated, with success, in cerebral, gastrointestinal, and muscle tissue, and shows promise in numerous indications involving tissue ischemia. In the current study, we propose to examine one hundred patients requiring either bypass or angioplasty due to chronic critical limb ischemia resulting from peripheral arterial disease. We intend to challenge patients before and after the intervention, using either an inflated blood pressure cuff or toe raises, to determine if oxygen saturation recovery time in the affected limb is correlated with symptom resolution (i.e. treatment success). Near-infrared spectroscopy will be performed using the ODISsey tissue oximeter developed by ViOptix, Inc. The proposed study will take approximately one year to complete enrolment, and has a follow-up period of 6 months post-intervention. Study Hypothesis: Knowledge of tissue oxygen saturation enhances clinical decision making in patients with chronic critical limb ischemia.

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.

Purpose is to test and validate a new questionnaire (the WELCH questionnaire) to estimate walking capacity in patients with claudication

This research project is investigating the relationship between body weight and function of the leg veins using a special non-invasive technique known as venous plethysmography.

Non-randomized, multi-center, longitudinal study of healthy subjects and subjects with PAD who are scheduled for ABI, TBI, and either Duplex Ultrasound or Angiographic assessments in a vascular clinic.

The purpose of this study was to evaluate whether an intensified multifactorial intervention program about cardiovascular risk factors in subjects with peripheral arterial disease (with and without diabetes mellitus), can improve the control of these factors (mainly hypercholesterolemia and hypertension) in relation to the habitual care
