Filter by:This study will assess the benefit of a neuromuscular electrical stimulation device in patients suffering from symptoms and effects of lower limb intermittent claudication.
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.
This study will assess the adjuvant benefit of a neuromuscular electrical stimulation device to standard treatment of supervised exercise in patients suffering from symptoms and effects of lower limb Intermittent Claudication.
1. To perform an observational analysis to determine if mean translesional gradient measurements (TLG) are associated with differences in clinical outcomes in patients with femoropopliteal arterial disease and claudication. 2. Hypothesis: Patients stratified by a residual translesional gradient </= 11 mmHg after peripheral revascularization or angiography alone will have better clinical outcomes than patients with TLG > 11 mmHg as assessed by six minute walk (6MW), walking impairment questionnaire scores (WIQ), ankle brachial index and need for repeat procedure at 6 months.
Peripheral arterial disease (PAD) due to lower limb arterial blockages affects significant proportion of the population with an age-adjusted prevalence of approximately 12%. Claudication induced walking impairment can be debilitating and adversely affects social, leisure, and occupational activities in many patients and is associated with higher mortality among PAD patients. Unfortunately, very few effective therapies are available to improve leg symptoms and exercise performance in PAD patients. Surgery is the last resort but results vary. Therefore, there is a large unmet need for medical therapies that can improve long-term walking performance and functional capacity in PAD patients. Danshen and Gegen (D&G) are commonly used Chinese herbal medicine in the treatment of cardiovascular diseases. D&G study has been extensively researched and continued at The Chinese University of Hong Kong (CUHK) for their antioxidative and vasodilator properties, modulate anti-atherosclerosis and improve arthrogenic athophysiology. Three randomized trials were completed at the CUHK showing D&G improved lipid profile, vascular function and thinned down the internal layer of the carotid artery. One may expect the same with lower limb arteries. Extensive clinical experiences of use in China and Hong Kong indicated that D&G are well tolerated and safe. This project is a randomized control trial to determine the efficacy and Safety of D&G in improving the functional capacity & QoL in patients with symptomatic PAD. The results of this study have the potential to change local and international practice in providing a much needed therapeutic option in the treatment of PAD.
The aim of the study is to evaluate whether walking capacity in patients with intermittent claudication is improved more by home-based 5+ exercise training than by current recommendations of daily walking. The study will elucidate if such a potential effect is dependent on changes in mitochondrial respiratory capacity, blood flow or both.
An evaluation of the safety and performance of the STANZA Drug-eluting Resorbable Scaffold (DRS) system for the treatment of patients with obstructive superficial femoral artery disease.
Study Objective: To compare patient outcomes following treatment with either the MILD procedure or epidural steroid injections (ESIs) in patients with painful lumbar spinal stenosis exhibiting neurogenic claudication and having verified ligamentum flavum hypertrophy as a contributing factor.
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 : 1. To determine the nature of the relationship between the recovery duration and subsequent walking performance. 2. To study the relationship between exercise ischemia, pain evolution and previous recovery duration. 3. To determine whether the experimental procedure influence the determination of an optimal of minimal recovery duration. 4. To study the influence of recovery duration on walking capacity from community-based measurement.
The primary objective of this study is to prove the superior performance of the Ranger™ paclitaxel-coated PTA balloon catheter for angioplasty for femoropopliteal artery lesions when compared to non-coated balloons at six months post-procedure when comparing Late Lumen Loss (LLL). Study statistical hypothesis: The %-mean loss of luminal diameter as assessed by angiography at six months follow-up after treatment of the femoropopliteal artery with Ranger DCB study devices is lower than the %-mean loss of luminal diameter after treatment with uncoated PTA balloon control devices.
