Filter by:The purpose of this post-market surveillance study will be to evaluate the real-world use of the DETOUR System in treated patients with symptomatic femoropopliteal lesions from 200 mm to 460 mm in length with chronic total occlusions (100 mm to 425 mm) or diffuse stenosis > 70% who may be considered suboptimal candidates for surgical or alternative endovascular treatments.
The aim of the study will be to evaluate shear stress and blood flow parameters in lower limb arteries during arm cycle ergometer exercise in participants with peripheral artery disease. Twenty patients participants with peripheral artery disease and claudication symptoms will be recruited. Participants will perform 3 experimental sessions in random order. Iarm-cranking (15 sets of two minutes exercise), warm water foot immersion, and control. During the interventions, blood pressure and heart rate will be assessed every 6 minutes. Measurements of arterial diameter, blood flow, anterograde and retrograde shear stress of the femoral artery will be evaluated using a two-dimensional ultrasound device with spectral Doppler.
This clinical trial aims to analyze the effects of concurrent vs aerobic training on glycemic control, ABI, functional capacity and disease-specific QOL among patients with Type-II DM-associated PAD at baseline & after 12 weeks of intervention. The main questions it aims to answer are: 1. Is concurrent training more effective than aerobic training in improving glycemic control among patients with Type-II DM-associated PAD? 2. Is concurrent training more effective than aerobic training in improving ABI among patients with Type-II DM-associated PAD? 3. Is concurrent training more effective than aerobic training in enhancing functional capacity among patients with Type-II DM-associated PAD? 4. Is concurrent training more effective than aerobic training in improving QOL among patients with Type-II DM-associated PAD? Signed informed consent will be taken before participation. For exercise training, Both will perform Warm up for 10 - 12 minutes, followed by 30 - 60 minutes of training protocol and then Cool down exercises for 10 - 12 minutes. Group A will perform concurrent training, whereas Group B will perform aerobic training.
The aim of this study is to analyze acute responses of arm-cranking exercise on cardiovascular function of peripheral arterial disease patients and compare it to the main exercise recommendation, walking exercise.
To evaluate the effectiveness of the VSX device in pre-determined patient populations to understand the patient characteristics that impact outcomes.
The purpose of this study is to evaluate the potential of ultrasound perfusion imaging technique for assessing the progression of peripheral arterial disease (PAD) and monitoring its response to therapy by measuring changes in microvessel alterations and perfusion variations.
The results of this study will serve as a starting point for future trials concentrating on the effectiveness and clinical outcomes of the procedures performed in an office based angiosuite. Additionally, other studies could compare clinical outcomes between procedures performed in an office based angiosuite and other settings.
Peripheral arterial disease (PAD) affects more than 200 million people worldwide. This disease occurs with narrowing and occlusion of arteries supplying oxygenated blood to the organs and limbs. Symptomatic patients typically experience leg pain with physical activity. More advanced disease states are referred to as critical limb ischemia (CLI), where patients may have leg pain at rest or non-healing wounds. Primary treatment of PAD involves risk factor management; smoking cessation, management of blood pressure, blood cholesterol, diabetes, and exercise prescription. Patients with CLI typically require interventions to reestablish blood supply to their limbs. There is currently minimal understanding of the role for exercise rehabilitation after revascularization procedures in this vulnerable population. This is the first clinical to understand the role of exercise for these patients. We hypothesize that exercise rehabilitation after revascularization will improve quality of life and functional capacity in these patients.
Cardiovascular disease (CVD), a condition predominantly caused by atherosclerosis, is the leading cause of morbidity and mortality in the investigator's society. Peripheral arterial disease (PAD), a subset of CVD, occurs when the atherosclerosis progresses to compromise the lower extremity circulation resulting in ischemic symptoms. Although atherosclerosis has been generally regarded as a disease of developed or affluent countries, recent evidence showed a progressive rise in the prevalence of CVD in developing countries where an epidemiological shift of disease prevalence patterns from infectious illnesses to atherosclerotic disease has occurred. Management of CVD, particularly with an emphasis of disease prevention, will undoubtedly play an increasing vital role in the health care system around the world. Endothelial dysfunction, as reflected by the impaired arterial vasodilatory capacity, represents one of the pathogenic mechanisms linking atherosclerosis and cardiovascular mortality. The ability of arteries to dilate in response to stimuli is a significant indicator of underlying vascular endothelial function and associated CVD. Factors modulating vasodilatory response include the release of vasoactive compounds such as nitric oxide (NO) from the endothelium and vascular compliance. In healthy individuals, a major mechanism responsible for vasodilation is the hyperemic-stimulated release of NO from the endothelium, resulting in vascular smooth muscle relaxation with subsequent vasodilation. Vascular endothelial function can be assessed using a non-invasive technique to determine brachial artery reactivity whereby a high-resolution ultrasound is used to measure changes in brachial artery diameter to endogenous production of endothelium-derived NO via flow-mediated dilation (FMD). Therefore, reduced FMD has been described as a reliable indicator of vascular endothelial dysfunction as well as presence of underlying CVD risk factors and related diseases. Recent studies have similarly shown that arterial pulse-wave velocity (PWV), which is a non-invasive evaluation of arterial stiffness, is a reliable indicator of vascular function. While numerous studies have documented the benefit of dietary intervention in the reduction of CVD related sequelae, limited data is available regarding whether the beneficial effect of dietary intervention are reflected in vascular endothelial function. The present study was therefore conducted to assess the effects of plant-based diet (PBD) on vascular endothelial function as assessed by FMD and PWV in patients with peripheral arterial disease (PAD).
This is an intersectional and interdisciplinary screening program in Viborg Municipality, including 67 years old citizens. This observational study will estimate the cost-effectiveness of a combined screening program for the following conditions: Abdominal aortic aneurysm, peripheral arterial disease, carotid plaque, hypertension, arrhythmia, and type-2-diabetes. Furthermore, the incidence of the outlined conditions will be described and so will the result of the intervention initiated (secondary medical prophylaxis, smoking cessation, introduction to nutritionally deficient diet etc.)
