Active clinical trials for "Peripheral Vascular Diseases"

In an observational multi-centre study (CHALLENGE), the effects were assessed of starting treatment with low doses of rosuvastatin in statin naive patients with a history of coronary heart disease (CHD), peripheral vascular disease (PVD), cerebrovascular accident (CVA), transient ischemic attack (TIA) or diabetes (DM), on low-density lipoprotein cholesterol (LDL-C) goal achievement. Also proportional changes in LDL-C, high-density lipoprotein cholesterol (HDL-C), total cholesterol (TC), triglycerides (TG) and the ratio TC/HDL-C were studied.

POLYTHESE® study is a retrospective, observational, multicentre, case series which examine short and long-term outcomes of using POLYTHESE®. This study will be done on Real World Data to describe the safety and performance of the device. PMCF Study.

This is a prospective, multi-center, observational registry to document the baseline, 24-hour and 30-day inflammatory response and procedural outcomes out to 12 month follow-up after femoropopliteal angioplasty or atherectomy-based revascularization procedures.

This is a single-arm, single-center, open-label, pilot study . 30 subjects with foot symptoms attributable to diabetes or peripheral vascular disease will be screened . Subjects meeting inclusion criteria will sign informed consent and enrolled. All 30 subjects will be treated with the Magic Foot™. If there is any significant improvement in ICG or foot symptoms as obtained from self evaluation questionnaire, a further 30 subjects will be enrolled.

The investigators hypothesize that among people with lower extremity peripheral artery disease (PAD), biomarker levels are higher during time periods immediately preceding an acute coronary event compared to time periods not immediately preceding an acute coronary event. Biomarkers the investigators will study are CRP, SAA, and D-dimer. Biomarkers will be measured at baseline and every two months during follow-up. The primary aims of this study are as follows. Specific Aim #1. Among participants with PAD who experience an acute coronary event during follow-up, the investigators will determine whether biomarker levels measured immediately prior to the coronary event are higher than levels that do not immediately precede coronary events. Specific Aim #2, Part 1. The investigators will determine whether participants who experience a coronary event (cases) have higher biomarker levels at the visit immediately prior to the event than participants who have not experienced a coronary event (controls) at the time of the case event. Specific Aim #2, Part 2. The investigators will determine whether participants who experience a coronary event (cases) have a greater increase in biomarkers during the time period leading up to the event compared to participants who have not experienced a coronary event (controls). To achieve these aims, the investigators will enroll up to 650 participants with PAD and follow them prospectively, measuring blood samples every two months, and ascertaining the presence of acute coronary events every two months.

Lower extremity peripheral arterial disease (LEPAD) is a highly prevalent chronic disease. Cardiovascular mortality of LEPAD patients at five years ranges between 18 to 30%. LEPAD is primarily caused by atherosclerosis that induces an inadequate blood flow to meet the tissues demand due to the narrowing of the arteries. An aggravation of the arterial lesions in LEPAD patients induces a worsening of patients' symptoms and a severe limitation of their walking capacity, contributing to an impairment of their quality of life. Despite maintaining a sufficient walking activity is essential for these patients, LEPAD patients lower their physical activity, which worsen the disease and potentially contribute to increase the risk of cardiovascular events and deaths. In a recent study in LEPAD patients, we showed, from a one hour GPS recording, a high variability of the patients' walking capacity (i.e., walking distances between two stops induced by lower limbs pain). Results suggested that in most patients previous stop duration before each walk was a predictor parameter of this walking variability. Whether there is an optimal or minimal recovery time influencing the walking capacity in LEPAD patients has never been studied. This study is a prospective, cross-sectional study in exercise pathophysiology. The main goal is to determine, following a walk that induces ischemia, the influence of the recovery duration on the subsequent walking performance in LEPAD patients. Secondary goals are : To determine the nature of the relationship between the recovery duration and subsequent walking performance. To study the relationship between exercise ischemia, pain evolution and previous recovery duration. To determine whether the experimental procedure influence the determination of an optimal of minimal recovery duration. To study the influence of recovery duration on walking capacity from community-based measurement.

This clinical investigation is intended to evaluate the ability of a magnetic cardiac positioning system to decrease medical radiation exposure on a peripheral angioplasty procedure in patients with a peripheral artery stenosis.

The Pedra Technologies' PedraTM device is a non-invasive, diagnostic device intended to measure foot perfusion by assessing blood flow. The PedraTM device comprises a compact instrument console connected to a sensor that is pasted onto the patient's foot during perfusion assessment. Through skin contact, the device is able to monitor tissue perfusion at depths of up to 7.5mm. The monitor console contains opto-electronic instrumentation including coherent infrared light sources, photo detectors, and display/control electronics. The sensor comprises passive fiber-optic conduits, which transfer infrared light from the console to the patient, and relays scattered light from the patient back to the console. The intensity of light emitted from the sensor is less than 3 mW, well within the safety envelope of Class I laser systems and comparable (or lower than) other commercially available devices such as laser Doppler systems. The sole point of contact with the patient is a layer of medical grade adhesive tape, which is used to paste the flat sensor onto intact skin.

The purpose of the BIOLUX P-III Spain registry is to further investigate the safety and clinical performance of the Passeo-18 Lux Drug Coated Balloon in the treatment of long atherosclerotic femoropoliteal artery lesions in daily clinical practice

This study evaluates the effects of Aspirin and thienopyridine resistance in relation to clinical cardiovascular outcomes as the genetic predictors of, and outcomes associated with aspirin and thienopyridine resistance in patients with peripheral arterial disease (PAD) currently remain unknown.
