Active clinical trials for "Peripheral Arterial Disease"

Circulating anti-beta2-glycoprotein antibodies have been associated with coronary artery disease and peripheral arterial disease. This auto-antibodies could activate endothelial cells leading to the expression of leukocyte adhesion molecules and increasing the release of pro-inflammatory cytokines. On the other hand, endothelial dysfunction of atherosclerotic patients acts as a primary pathogenic event, as it occur before structural changes are evident on angiogram or ultrasound scan. Loss of endothelial normal function causes vasoconstriction, local coagulation alterations and an increase arterial wall proliferation. This situation s been attributed to a reduction in nitric oxide bioactivity, and to an increase oxygen-free radical formation in the context of the pro-inflammatory status found in atherosclerosis. Hypothesis: Circulating Anti-beta2-glycoprotein I antibodies could be associated with endothelial dysfunction and nitric oxide metabolism disruption en patients with peripheral arterial disease.

Current evidence cannot explain the clinical features of peripheral arterial disease only from the principle of reduced blood flow. Explanations have therefore in addition been linked to mitochondrial dysfunction of skeletal muscles. This study will elucidate whether there is a relation between clinical variables of the different levels of arterial insufficiency in peripheral arterial disease and mitochondrial respiratory capacity.

To collect data from real-world use with the Chocolate PTA Balloon Catheter to support the effectiveness of the device for use during percutaneous transluminal angioplasty (PTA) procedures.

The primary purpose of this study is to assess safety and efficacy of the Drug Eluting Balloon (DEB) technology for the treatment of the Superficial Femoral Artery (SFA) ischemic obstructive vascular disease in patients presenting with long lesions. As secondary aim this study is going to explore treatment effect on a number of procedural and clinical endpoints in order to collect information to design a future comparative effectiveness study.

The main purposes of this study are: to describe the prevalence of peripheral artery disease (including lower extremity artery disease, carotid artery disease, renal artery disease, and abdominal aortic disease) in patients with acute myocardial infarction in comparison to control subject from the general population, to evaluate the association of peripheral artery disease with glucometabolic status in patients with acute myocardial infarction, to assess the prevalence of type D personality in patients with acute myocardial infarction com pared to control subjects from the general population, to examine the prognostic value of peripheral artery disease in patients with acute myocardial infartion, and to evaluate the prognostic value of type D personality in patients with acute myocardial infarction.

This will be an observational study comparing the plasma levels of free hydrogen sulfide in patients with and without peripheral arterial disease using a novel recently published method of measuring hydrogen sulfide. The investigators will also see if there is any difference in these levels between symptomatic and asymptomatic patients. Will examine the relationship of these levels to known clinical risk factors as well as plasma nitrite and nitric oxide levels. In doing the above the investigators hope to explore the utility of free hydrogen sulfide as a biomarker for peripheral arterial disease. Atherosclerotic peripheral arterial disease (PAD) of the lower extremities represents a significant and growing cause of morbidity and mortality. The PARTNERS study of screening ABIs in a primary care population of nearly 7000 individuals demonstrated a remarkable 29% incidence of ABI <0.9, which is the commonly accepted level of abnormal ABI diagnostic of PAD. Also of note in these patients with a new diagnosis of PAD the incidence of asymptomatic PAD was a striking 48%. The availability of a biomarker will greatly enhance the care of these patient and hopefully reduce morbidity and mortality. The investigators believe that hydrogen sulfide (H2S), an endogenously produced gasotransmitter, holds promise as a clinically useful biomarker for PAD and may also provide a possible explanation for the paradox of asymptomatic PAD in patients with ABIs less than 0.9. To date, research regarding H2S has demonstrated that it participates in a myriad of physiological functions including vasodilatation, anti-apoptotic effects, modulation of mitochondrial respiration, and changes in vascular remodeling.

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.
