Filter by:The primary aim of this clinical study is to assess the safety and clinical performance of the BRight drug-coated balloon (DCB) in the treatment of lower limb arteries stenosis in subjects with Peripheral Artery Disease (PAD). The primary endpoint will be Late Lumen Loss (LLL) of the target lesion at 6 months.
A cross-sectional, non-interventional study to assess walking performance, vascular function, and lower limb calcification in subjects with peripheral artery disease and end-stage kidney disease (PAD-ESKD) receiving hemodialysis.
one-centered, open, non-randomized, controlled clinical trial will focus on a comprehensive study of the clinical, functional and molecular biochemical characteristics of the natural course of COPD in combination with peripheral atherosclerosis
The objective of this study is to determine if patients with lower extremity wounds in rural communities who undergo specialty referral through telemedicine have expedited care compared to patients who are treated through standard in person referral.
The study will focus on effectiveness and safety of rivaroxaban (Xarelto) when given together with acetylsalicylic acid (combination therapy) to patients suffering from coronary artery disease (a condition that affects the blood vessels supplying the heart) and / or peripheral artery disease (a condition that affects the blood vessels of the lower limbs) in the routine clinical practice. The study will help to collect data for prevention cardiovascular death, myocardial infarction (MI), stroke and major adverse limb events in adult patients. The study will focus on information on when and why physicians are starting to treat patients with combination therapy, treatment duration, reasons to discontinue treatment and previous therapies. The study will also investigate treatment outcomes for patients being treated with a combination therapy by their physicians.
This study intends to evaluate the efficacy of a multidisciplinary vascular care team utilizing an intensive guideline-based lipid reduction program in improving risk factor modification as measured by LDL-C reduction at 12 months in patients with peripheral artery disease (PAD). An additional objective is to understand the potential reach and impact if this program were extended across the University of Colorado Healthcare (UC Health) System.
The study is aimed at evaluating the role of the activity of the key hemostatic parameters of endothelial dysfunction (nitric oxide II (NO) metabolites, plasmin activator inhibitor-1 (PAI-1), von Willebrand factor (vWF), coagulation factor VIII (FVIII), soluble endothelial protein C receptors (sEPCR)) in the development of disease progression, thrombotic complications and restenosis in subjects with atherosclerotic peripheral artery disease.
This study postulates that the application of Sirolimus, an anti-proliferative agent that inhibits neointimal hyperplasia, via Sirolimus coated balloon (SCB) will be safe and will result in better arterial patency in infrainguinal peripheral arterial disease (PAD). The aim is to evaluate the efficacy (12 month freedom from clinically driven target lesion revascularisation) and safety (freedom from major adverse events) of sirolimus coated balloons in the treatment of infrainguinal PAD.
Digital Variance Angiography (DVA) is a new tool in medical imaging with proven image quality reserve. The previously observed quality reserve of Digital Variance Angiography (DVA) in lower extremity angiographies, allowed to lower radiation exposure by 70 % during DSA in lower extremity diagnostic angiographies with non-inferior image quality. The aim of this study is to apply this non-inferior image quality and use it for radiation exposure reduction in diagnostic lower limb angiography. The project would prospectively block-randomise (50:50) patients, who undergo elective diagnostic angiography into two groups: a comparator group examined by means of conventional DSA using a standard care protocol (Siemens Artis Zee, Extremities Care setting, 1.2 µGy/frame) (Group B) and a study group examined by means of DVA using a low-dose protocol (0.36 µGy/frame corresponding to 70% decrease of radiation dose) (Group A). During each procedure the investigators record radiation exposure (cumulative dosage, dose area product) and contrast media usage and procedural time then compare the results of the groups. Qualitative image review is done to compare conventional DSA and reduced radiation exposure DVA images after image acquisition. Our hypothesis is that with the previously proven non-inferior image quality, the investigators will be able to reduce radiation exposure of the participants and also staff members in everyday clinical practice.
Although the benefits of supervised walking training in patients with peripheral arterial disease (PAD) and symptoms of intermittent claudication (IC) are well established, one of the main problems found in this type of protocol is low adherence to training, which is possibly related to pain during training. In addition, little is known about the impact of performing exercise with pain on cerebral blood flow and cardiovascular health indicators. Thus, the objective of the present study will be to analyze the acute effects of walking exercise with self-selected intensity on the cardiovascular health indicators of patients with PAD. Therefore, 17 patients with PAD will undergo three experimental sessions: exercise with self-selected intensity, exercise until maximum pain and control. The responses of the cardiovascular variables (heart rate variability, blood pressure, heart rate, arterial stiffness and endothelial function) will be obtained before and after the sessions. In addition, during the session cardiovascular responses (cerebral blood flow, blood pressure and heart rate), perceptual and affective responses, as well as information about the exercises performed during the session will be obtained. The responses before and after exercise will be analyzed using the two-way analysis of variance for repeated measures (ANOVA) and the Newman-Keuls post-hoc test. The value of P <0.05 will be considered significant.
