The Effects of Claudication Severity on Functional Outcomes

Intermittent Claudication

Peripheral artery disease (PAD) affects over 236 million people globally. A classic symptom of PAD is intermittent claudication (IC) which is associated with reductions in physical function. The evidence is irrefutable that supervised exercise programmes (SEP) improve pain free and maximal waking distance. However, adherence rates are poor with exercise-related pain cited as contributable factor. Exercise at mild claudication or pain- free exercise improves walking ability, however current guidelines recommend exercise should be performed to near maximal claudication to improve walking ability. Conflicting evidence exists and there is a lack of evidence that has directly compared the relative effects of exercise prescribed at different levels of claudication. Therefore, the primary objective is to directly compare the effects of exercise prescribed at different levels of claudication pain on functional outcomes

Study of the R3 Vascular Drug-Eluting Bioresorbable Scaffold in Treating Below the Knee Arterial...

Peripheral Arterial DiseaseAtherosclerotic Lesion2 more

This first-in-human clinical feasibility study will evaluate the safety and performance of the R3 Vascular MAGNITUDE® Bioresorbable Drug-Eluting Scaffold and Delivery System in patients undergoing treatment for peripheral arterial disease severe enough to have significantly reduced the blood supply to their leg. The severe reduction in blood flow causes lifestyle limiting leg pain for these patients, and may lead to amputation of the affected limb due to the loss of tissue in the leg or foot from ulcers or gangrene. The investigational device being studied in this trial is intended to restore blood flow to the affected limb, providing symptomatic relief to the patient and reducing the risk of limb amputation. The scaffold is a type of vascular stent placed within the diseased artery below the knee to improve blood flow. Unlike commercially available metallic stents which are permanently placed within the artery, the MAGNITUDE® Bioresorbable scaffold is made of a polymer material that will completely dissolve away over time, providing the support necessary to the artery while it is healing after the treatment procedure and then slowly disappearing from the artery once that support is no longer needed. The investigational scaffold has been successfully used to treat vascular blockages in the coronary arteries of the heart, but the RESOLV I study will be the first time this device has been used to improve blood flow in the arteries of the lower leg. Patients enrolled in this study may have up to three vascular blockages in their lower leg arteries treated with the MAGNITUDE® Bioresorbable scaffold, and then will be assessed over the course of the following five years to evaluate whether the investigational treatment was successful in safely alleviating their leg pain and other symptoms.

Personalised Activity Plan for BREAKing UP Sitting Time in Patients With Peripheral Arterial Disease...

Peripheral Arterial Disease

Intermittent claudication is the most common manifestation of peripheral arterial disease, a common cardiovascular disease that causes blocked blood vessels (arteries) in the leg. Symptoms consist of persistent pain in one or both legs during exercise that is relieved with rest. Evidence suggests that high levels of uninterrupted sitting and sedentary behaviour are associated with cardiovascular disease risk, mortality and all-cause mortality. One of the main goals for treating people with intermittent claudication, is increased participation in physical activity. Supervised Exercise Programmes are recommended however these are not well tolerated and compliance is low. Alternative exercise, including short bouts of physical activity to break up sedentary time, has been suggested to help improve physical function. This study will investigate whether alternative exercise, in the form of breaking up prolonged sitting time, will improve physical function in patients with intermittent claudication. Patients will be screened during their routine clinic appointment at Glenfield Hospital. All other study activity will take place at the patients home. Activity monitors will be worn for up to 8 days at baseline and follow-up, measuring step count and time, inactivity, activity time and intensity, and sleep duration. Participants will also be expected to wear activity monitors for the duration of the 8-week intervention to measure steps. Participants will be in the study for up to 18 weeks in total.

Paclitaxel Eluting Stent in Long SFA Obstruction: A Prospective, Randomized Comparison With Bypass...

Chronic Lower Limb IschemiaPeripheral Athero Obstructive Disease2 more

Chronic lower limb ischemia due to atherosclerosis causes significant morbidity especially in elderly: the prevalence of asymptomatic obstructive peripheral atherosclerosis among 40-74 old is 4-22%. The prevalence of its milder symptomatic manifestation, intermittent claudication among 40 years old men is about 1% and among 70 years old it is 7%. In about 10% of the patients the ischemia worsens to threat the vitality of the limb. Although intermittent claudication has a benign prognosis and can often treated conservatively, more severe forms with extensive arterial obstructions require revascularization, either open surgical or endovascular. Surgical bypass operations are currently the standard reference for treating long femoral artery obstructions. Surgical bypass operations are accompanied by significant acute complications and late adverse effects, especially in patients with associated cardio-cerebrovascular and pulmonary diseases, and less invasive, safe, and effective endovascular therapies are seeked for. The long term patency rates of infrainguinal balloon angioplasty (PTA) vary largely in different studies but they are mostly poor when long femoral arterial obstructions have been treated. Drug eluting stents have shown great promise in coronary artery interventions. The purpose of this study is to compare Paclitaxel eluting Zilver PTX nitinol stent (Cook INC) with bypass surgery using PTFE graft to proximal popliteal artery in the treatment of long femoral artery obstructions (total length of 10-25 cm) in a prospective, randomized, Finnish multi center trial with consecutive claudicant and chronic critical ischemia patients. The aim is to randomize altogether 400 patients during about two years in five universities and in 2-3 central hospitals. The primary end point is patency at 24 month follow up. Secondary end points are primary success at patient discharge, complications, 30-day mortality, target lesion revascularization, quality of life, and economical analysis.

Arm-crank Exercise Training on Cardiovascular Function of Patients With Peripheral Artery Disease...

Peripheral Arterial DiseaseIntermittent Claudication1 more

The aim of the study is to analyze the effect of 12 weeks of arm crank exercise (ACE) training on cardiovascular function in PAD patients, and compare it with treadmill exercise (TE), the actual recommendation for this patients. In this clinical trial, 45 patients will be allocated randomly in three experimental groups: ACE training, TE and control group. ACE and TE groups will perform exercises twice a week with the intensity equivalent to 13- 15 on Borg's Subjective Perception Exertion Scale. Patients in control group will meet twice a week, however only to perform diverse activities and group living, without any type of exercise involved. All groups will be encouraged to increase their levels of activity, as they are usually guided in medical consultations. Before and after 12 weeks of intervention, cardiovascular function, functional capacity, cognition, and quality of life will be assessed.

Telehealth Exercise Training in Peripheral Arterial Disease - TEXT-PAD

Peripheral Arterial DiseaseIntermittent Claudication3 more

Peripheral arterial disease is a common, undertreated and under-researched issue. The vast majority of these patients often have multiple issues which can be improved with targeted behavioural change interventions. NICE has recommended that supervised exercise is the main stay of treatment for intermittent claudication (ischaemic muscle pain on walking due to blocked and narrowed arteries). However, in the vast majority of UK hospitals this isn't undertaken and with the issues around group-based sessions and repeated visits to hospitals this treatment option is not available with the coronavirus pandemic. We proposed a single centre randomised control trial in 60 patients with peripheral arterial disease attending the Freeman Hospital. Patients will be randomised to either an enhanced behavioural change intervention targeting multiple health behaviours vs a simple walking intervention. We will also be embedding focus groups to understand patients experience of the intervention and whether the intervention is feasible and acceptable allowing changes to be made to the program. The primary outcome will be to assess the feasibility and acceptability of the program. We will also be assessing multiple secondary outcomes including functional capacity, quality of life, sleep quality and smoking and alcohol reduction.
