Active clinical trials for "Peripheral Vascular Diseases"

Prevalence of diabetes mellitus (DM) is increasing rapidly, with patient numbers projected to rise to 643 million by 2030. As a consequence of diabetes-related atherosclerosis, peripheral arterial disease (PAD) and in particular medial arterial calcification (MAC) can occur. The accurate identification of PAD by bedside tests is extremely important in patients with diabetes and foot ulceration, in order to reduce delayed wound healing, prevent lower limb amputation and eventually reduce mortality. However, as shown in previous systematic reviews, the performance of current bedside tests is not reliable in excluding PAD in diabetic patients.1,2 Moreover, the methodological quality of the conducted studies is generally poor. Therefore, more reliable and prospective data is required. Also alternative bedside tests need to be investigated. As an example, the ACCmax (a new doppler derived parameter) could be particularly promising in this patient group.

The main objective of this study is to assess in-stent late lumen loss in diabetic patients with de novo native coronary lesions using the sirolimus-eluting Bx VELOCITYä stent as compared to the Bx VELOCITY balloon-expandable stent.

Patients undergoing elective revascularization of their peripheral artery disease will be randomized to a prehabilitation program or usual care prior to their scheduled procedure.

To compare the outcome of bypass surgery and plaque excision for treatment of critical limb ischemia in the lower limbs

The goal of this study is to evaluate whether supervised treadmill exercise combined with ranolazine 1000 mg twice daily provides an incremental benefit in absolute walking distance over supervised exercise alone in patients with stable claudication. Investigators also seek to determine if the administration of ranolazine provides a sustained benefit after the completion of a supervised exercise regimen. Lastly, investigators wish to determine whether both exercise and ranolazine improves peak oxygen consumption and anaerobic threshold in patients with stable claudication.

Isthmus Logic Carbostent™ is a CE-marked cobalt chromium stent with a bio inducer surface for the treatment of peripheral iliac artery disease. The aim of this post-market retrospective study protocl P22202 is to collect clinical data of patients treated with Isthmus Logic for the treatment of peripheral iliac artery disease in routine clinical practice. In order to obtain long-term follow-up data, the data collection will be limited to patients that have been treated with these devices at least 12 months prior to the study start.

To utilize near-infrared spectroscopy to investigate if the research device, which induces muscle stretching, and creatine loading impact submaximal exercise performance in aged and PAD patients. Near-infrared spectroscopy (NIRS)-derived tissue oxygenation responses will be obtained during device placement (muscle stretch) and during a walking test (i.e., six-minute walk test). Muscle oxygenation at rest and during device placement will be assessed with Magnetic Resonance Imaging. It is hypothesized that the stretching protocol will improve both NIRS-derived tissue oxygenation and magnetic resonance-derived muscle oxygenation and that creatine supplementation will further improve phosphorus metabolite muscle performance. All patients will undergo either 4 weeks of stretch training with- or- without creatine supplementation according to previously defined creatine guidelines.

The study aims to evaluate the efficacy of an arginine enriched oral nutritional supplement in the prevention of wound complications in the the wounds of patients post lower limb revascularization.

In 2010, we completed a phase 1 to 2a clinical trial of pCMV-vegf165 in patients with chronic lower limb ischemia (stage 2a to 3 according to Fontaine classification modified by A. V. Pokrovsky) who were not suitable for reconstructive surgery or endovascular treatment. This study demonstrated the safety, feasibility, and short-term(3 months) efficacy of pCMV-vegf165 gene transfer,12,13which lead to conducting a phase 2b to 3 multicenter clinical trial. The study was conducted under the control of the Russian Ministry of Health and was completed in 2011. Patients enrolled in the study were subjected to a 6-month

A Physician initiated PMCF Trial Investigating the BeSmooth Peripheral Stent System for the treatment of Iliac Lesions. The objective of this clinical investigation is to evaluate the long-term safety and efficacy of the BeSmooth Peripheral Stent System in clinical settings post CE-certification when used according to the indications of the IFU.
