Abstract
PURPOSE To compare arm-ergometry and treadmill supervised exercise training on cardiorespiratory fitness and walking distances in patients with peripheral artery disease (PAD). METHODS ARMEX was a single-center, single-blinded, parallel group, non-inferiority trial enrolling symptomatic patients with PAD. Patients were randomized (1:1 ratio) to a 12-wk arm-ergometry (AEx) or standard treadmill (TEx) supervised exercise training protocol. The powered primary end point was the change in peak oxygen uptake (VO 2 ) at 12 wk, measured on a treadmill cardiopulmonary exercise test (CPX). Secondary outcomes included changes in VO 2 at the first ventilatory threshold (VT-1), ventilatory efficiency (ratio of minute ventilation [VE] to carbon dioxide production [VCO 2 ], VE/VCO 2 ), walking distances by CPX and 6-min walking test (6MWT), and self-reported walking limitations. RESULTS Fifty-six patients (66 ± 8 yr; 88% male) were randomized (AEx, n = 28; TEx, n = 28). At 12 wk, VO 2peak change was not significantly different between groups (0.75 mL/kg/min; 95% CI, -0.94 to 2.44; P = .378), despite a significant increase only in AEx. VO 2 at VT-1 improved in both groups without between-group differences, and VE/VCO 2 slope improved more in AEx. The TEx attained greater improvements in walking distance by CPX (121.08 m; 95% CI, 24.49-217.66; P = .015) and 6MWT (25.08 m; 95% CI, 5.87-44.29; P = .012) and self-perceived walking distance. CONCLUSIONS Arm-ergometry was noninferior to standard treadmill training for VO 2peak , and treadmill training was associated with greater improvements in walking distance. Our data support the use of treadmill as a first-line choice in patients with PAD to enhance walking capacity, but arm-ergometry could be an option in selected patients.

Abstract
INTRODUCTION Peripheral arterial disease (PAD) is an occlusive atherosclerotic disease of the arteries of the extremities of the body that affects more than 230 million people worldwide. The most common symptom is intermittent claudication, described as leg pain which occurs mainly while walking. The symptoms impair the ambulation and functional capacity of patients, leading to loss of mobility, disease deterioration, increased risk of other cardiovascular diseases, and lower quality of life (QoL). Therefore, the aim of this study was to perform a cross-cultural adaptation and validation of the VascuQol-6 questionnaire for the Portuguese population to obtain a quick, sensitive, and easy-to-use way to assess the QoL of Portuguese patients diagnosed with PAD. METHODS The Vascular Quality of Life-6 Questionnaire (VascuQoL-6) was adapted and translated into European Portuguese using standard validation methodology, including 115 patients with a mean age of 64.67 (7.23) years, with PAD with IC stable for more than three months; and ABI < 0.9 at rest. VascuQoL-6, SF-36, International Physical Activity Questionnaire (IPAQ), and the PAD Knowledge Questionnaire (PADKQ) were used. Reliability, construct validity analysis through convergent and discriminant validity, known-group validity, and responsiveness analysis were tested. RESULTS The Cronbach's alpha was 0.64 and the average inter-item correlation was 0.27, indicating acceptable internal consistency. VascuQoL-6 was positively associated with SF-36 Physical Component Summary and Mental Component Summary scores (r = 0.64, p < 0.01 and r = 0.42, p < 0.01, respectively). In turn, there was no significant correlation between VascuQoL-6 scores and the PADKQ or IPAQ. A statistically significant difference between groups according to IC severity [F(2.47) = 8.35, p < 0.001] was found. A paired samples t-test showed differences between VascuQol-6 scores before a walking program (M = 15.65, SD = 3.09), and after a walking program (M = 17.41, SD = 2.71), t(67) = 3.94, p ≤ 0.001. CONCLUSION The VascuQoL-6 is a six-item instrument to assess the QoL associated with PAD with good psychometric properties, convergent and discriminant validity with SF-36, PADKQ and IPAQ. The instrument proved to have known group validity and responsiveness.

Abstract
Background Peripheral arterial disease is one of the leading complications of type 2 diabetes mellitus. The primary symptom of peripheral arterial disease is claudication pain. Exercise is known to improve the claudication pain, thereby improving the quality of life. Methods A total of 74 participants were recruited in each group and a detailed demographic assessment was done for all the participants. The study group received a comprehensive structured exercise program and standard care whereas the control group received only the standard care. Progression of the exercise was made at the 6th week of the protocol. All the outcome measures were reassessed after the 12th weeks for both study and control group. Results The mean age of participants was 60.78 ± 11.29 (years) and 59.98 ± 11.42 (years) for the study and control group, respectively. There was a statistically significant difference in toe brachial index (p < 0.001), ankle brachial index (p < 0.001), 6-minute walk distance (p < 0.001), WHO-BREF quality of life questionnaire (p < 0.001), and walking ability ((p < 0.001) in the study group in comparison to the control group. Conclusion In the present study we found that comprehensive structured exercise program improves the arterial indices, quality of life, walking ability and reduces claudication pain in type 2 diabetes mellitus with peripheral arterial disease.

Abstract
BACKGROUND Supervised exercise programs are used to treat intermittent claudication (IC). Home-based exercise programs have been developed to lower barriers to participation. We studied the effects of one such exercise program (TeGeCoach) on self-reported walking ability in patients with IC. METHODS In a pragmatic multicenter randomized controlled trial (registration number NCT03496948), 1982 patients with symp - tomatic IC insured by one of three German statutory health insurance funds received either telephone health coaching with remote exercise monitoring (TeGeCoach; n = 994) or routine care (n = 988). The primary outcome was the change in Walking Impairment Questionnaire (WIQ) scores after 12 and 24 months in the intention-to-treat population. The secondary outcomes were healthrelated quality of life, symptoms of depression or anxiety, health competence, patient activation, alcohol use, and nicotine depen - dence. RESULTS There was a significant group difference in WIQ score in favor of TeGeCoach (p < 0.0001), amounting to 6.30 points at 12 months (Bonferroni-corrected 95% CI [4.02; 8.59], Cohen's d = 0.26) and 4.55 points at 24 months ([2.20; 6.91], d = 0.19). Some of the secondary outcomes also showed positive results in favor of TeGeCoach at 12 months with small effect sizes (d ≥ 0.20), including physical health-related quality of life and patient activation. The average daily step count was not higher in the TeGeCoach group. CONCLUSION Significant improvements regarding symptom burden demonstrate the benefit of a home-based exercise program and thus expand the opportunities for guideline-oriented treatment of IC. Future studies should additionally address the effect of home-based exercise programs on clinical variables by means of, for example, the 6-minute walk test.

Abstract
BACKGROUND The most common symptom of peripheral artery disease (PAD) is intermittent claudication that involves the calf, thigh, and/or buttock muscles. How the specific location of this leg pain is related to altered gait, however, is unknown. OBJECTIVES We hypothesized that because the location of claudication symptoms uniquely affects different leg muscle groups in people with PAD, this would produce distinctive walking patterns. METHODS A total of 105 participants with PAD and 35 age-matched older volunteers without PAD (CTRL) were recruited. Participants completed walking impairment questionnaires (WIQ), Gardner-Skinner progressive treadmill tests, the six-minute walk test, and we performed an advanced evaluation of the biomechanics of their overground walking. Participants with PAD were categorized into 4 groups according to their stated pain location(s): calf only (C, n = 43); thigh and calf (TC, n = 18); buttock and calf (BC, n = 15); or buttock, thigh, and calf (BTC, n = 29). Outcomes were compared between CTRL, C, TC, BC and BTC groups using a one-way ANOVA with post-hoc comparisons to identify and assess statistically significant differences. RESULTS There were no significant differences between CTRL, C, TC, BC and BTC groups in distances walked or walking speed when either pain-free or experiencing claudication pain. Each participant with PAD had significantly dysfunctional biomechanical gait parameters, even when pain-free, when compared to CTRL (pain-free) walking data. During pain-free walking, out of the 18 gait parameters evaluated, we only identified significant differences in hip power generation during push-off (in C and TC groups) and in knee power absorption during weight acceptance (in TC and BC groups). There were no between-group differences in gait parameters while people with PAD were walking with claudication pain. CONCLUSIONS Our data demonstrate that PAD affects the ischemic lower extremities in a diffuse manner irrespective of the location of claudication symptoms.

Abstract
INTRODUCTION Peripheral arterial disease (PAD) is increasingly prevalent, and supervised physical exercise programmes are recommended as the first-line treatment. However, these programmes are underused. Alternative delivery models may be able to expand treatment coverage. The objective of this study was to compare a home-based exercise programme (HBEP) and a centre-based exercise (CBE) in terms of their effects on functional capacity, peripheral muscle oxygenation and quality of life in individuals with PAD. METHODS AND ANALYSIS This single-blind, parallel randomised clinical trial will consist of two groups: HBEP and CBE. A qualitative analysis will be carried out to investigate acceptability and satisfaction. The primary outcome will be functional capacity, assessed by the incremental shuttle walk test. Secondary outcomes will include functional capacity, assessed by a treadmill walking test; peripheral muscle oxygenation and quality of life; and self-reported functional impairment, risk factors, morbidity, level of physical activity, adherence, acceptability and satisfaction. The intervention protocols will consist of 12 weeks of intermittent walking until claudication symptoms, three times a week. Participants randomly assigned to the CBE group will participate in supervised face-to-face sessions. The HBEP group will perform exercises at home with remote supervision, monitored by a pedometer and heart rate monitor, and subjective perception of effort during each session will be recorded by participants in a training diary; follow-up will be conducted by telephone calls. Statistical analyses will follow the intention-to-treat principle. Participants allocated to the HBEP group will be interviewed about their experience of remote treatment using a qualitative approach. ETHICS AND DISSEMINATION Ethics approval was obtained from the Ethics Committee of the Universidade Federal de Minas Gerais. The results will be disseminated in a peer-reviewed journal and presented at international congresses. This research has the potential to improve the care of people with PAD because if home-based rehabilitation demonstrates effectiveness, it could be considered an alternative or support resource to the usual centre-based treatment models, expanding access, coverage and participation in vascular physiotherapy TRIAL REGISTRATION: https://ensaiosclinicos.gov.br/rg/RBR-97vy9n7 on 14 April 2022.

Abstract
INTRODUCTION The Walking Impairment Questionnaire (WIQ) is a common and easy-to-use assessment of walking incapacity in people with claudication due to peripheral artery disease (PAD). It has four subscales: pain severity, walking distance, walking speed, and ability to climb stairs. It has not been translated into Gujarati, which limits its use in Indian subjects. AIM This study aims to translate and assess the validity and reliability of a Gujarati version of WIQ. MATERIALS AND METHODS This study had three phases: 1. Forward and backward translation and Cultural adaptation of WIQ into the Gujarati language by two independent translators, 2. Face and content validation by six clinical reviewers and 10 participants with PAD and Type II diabetes, 3. Concurrent and construct validity, test-retest reliability, and internal consistency of Gujarati, the WIQ was assessed on 160 participants with PAD and Type II diabetes who had a mean Ankle Brachial Index (standard deviation) <0.40 (0.1). The concurrent and construct validity of the WIQ was analyzed by correlating the WIQ distance and speed score with 6-minute walk distance (6MWD) and speed and WIQ total score with the Medical Outcome Study Questionnaire Short Form 36 (SF-36) score using Pearson's correlation coefficient. Test-retest reliability was analyzed using an intraclass correlation coefficient (ICC) with a seven-day interval between two questionnaire applications. Internal consistency of the total WIQ score was determined using Cronbach's alpha. RESULTS Following translation, the Gujarati WIQ was considered acceptable and understandable by people with PAD. There was excellent correlation between the WIQ distance score and 6-minute walk test distance (r = 0.95, P < .05)) , the WIQ speed score and 6-minute walk test speed score (r = 0.89, P < .05)) and the Gujarati WIQ total score and total score of physical functioning domain of SF- 36 (r = 0.99, P < .05). There was excellent test-retest reliability over 7 days for total WIQ score (ICC = 0.94). The Cronbach's alpha for internal consistency of 0.97 for total WIQ score were excellent. This demonstrates the sufficient homogeneity of the total questionnaire. CONCLUSION The Gujarati version of the WIQ is reliable and valid and can be used to assess self-reported walking impairment in Gujarati-speaking people with PAD and Type II Diabetes.

Abstract
BACKGROUND To explore the influence of sociodemographic, behavioral, clinical, and anthropometric factors on the association between sex and functional capacity in patients with peripheral arterial disease. METHODS A cross-sectional study was conducted with patients aged more than 45 years, diagnosed with peripheral artery disease (PAD), from 2 Brazilian hospitals. Data on sociodemographic characteristics, behavioral risk factors, clinical profile, and anthropometric measurements were collected. Functional capacity was assessed using the 6-min walk test and the Walking Impairment Questionnaire. Statistical analyses, including t-tests, chi-square tests, and logistic regression, were performed to assess the relationships between sex, functional capacity, and potential influencing factors. RESULTS Among the 262 patients with PAD, 67 were women and 113 were men. Women exhibited lower absolute functional capacity and lower Walking Impairment Questionnaire scores compared to men, even after adjusting for potential confounders. However, relative functional capacity did not significantly differ between sexes after adjusting for variables. Pain-free walking distance was also lower in women compared to that in men, but this association lost significance after adjusting for sociodemographic factors. CONCLUSIONS Women with PAD had lower absolute functional capacity compared to men, influenced by various factors such as sociodemographic, behavioral, clinical, and anthropometric factors. However, the relative functional capacity was similar between genders, being influenced only by behavioral factors, while for the distance walked until pain, the association was lost after adjustments for sociodemographic factors.

Abstract
Herein, we report a case of intermittent claudication (IC) caused by Buerger's disease (thromboangiitis obliterans {TAO}), which we treated using supervised exercise therapy (SET). The patient was a 58-year-old male with a history of smoking who presented with IC and resting pain in the right lower extremity, which had led to necrosis of the right first toe eight years prior to presentation. The non-healing right first toe was amputated and the patient underwent angiogenesis therapy in the right lower extremity. Despite continued strict smoking cessation and antiplatelet medication, the patient presented with IC of the left lower extremity eight years after the previous symptoms. Therefore, the patient underwent SET once a week (40 min per session) for five months, resulting in a total of 21 sessions. Consequently, the patient's walking ability and quality of life (QoL) significantly improved. These results suggest that SET is an effective treatment for TAO-induced IC. However, further studies are required to demonstrate its efficacy.

Abstract
BACKGROUND Lower extremity atherosclerotic disease (LEAD) - also known as peripheral arterial disease - refers to the obstruction or narrowing of the large arteries of the lower limbs, most commonly caused by atheromatous plaque. Although in many cases of less severe disease patients can be asymptomatic, the major clinical manifestations of LEAD are intermittent claudication (IC) and critical limb ischaemia, also known as chronic limb-threatening ischaemia (CLTI). Revascularisation procedures including angioplasty, stenting, and bypass grafting may be required for those in whom the disease is severe or does not improve with non-surgical interventions. Maintaining vessel patency after revascularisation remains a challenge for vascular surgeons, since approximately 30% of vein grafts may present with restenosis in the first year due to myointimal hyperplasia. Restenosis can also occur after angioplasty and stenting. Restenosis and occlusions that occur more than two years after the procedure are generally related to progression of the atherosclerosis. Surveillance programmes with duplex ultrasound (DUS) scanning as part of postoperative care may facilitate early diagnosis of restenosis and help avoid amputation in people who have undergone revascularisation. OBJECTIVES To assess the effects of DUS versus pulse palpation, arterial pressure index, angiography, or any combination of these, for surveillance of lower limb revascularisation in people with LEAD. SEARCH METHODS The Cochrane Vascular Information Specialist searched the Cochrane Vascular Specialised Register, CENTRAL, MEDLINE, Embase, CINAHL, and LILACS databases and World Health Organization International Clinical Trials Registry Platform and ClinicalTrials.gov trials registers to 1 February 2022. SELECTION CRITERIA We included randomised controlled trials (RCTs) and quasi-RCTs that compared DUS surveillance after lower limb revascularisation versus clinical surveillance characterised by medical examination with pulse palpation, with or without any other objective test, such as arterial pressure index measures (e.g. ankle-brachial index (ABI) or toe brachial index (TBI)). Our primary outcomes were limb salvage rate, vessel or graft secondary patency, and adverse events resulting from DUS surveillance. Secondary outcomes were all-cause mortality, functional walking ability assessed by walking distance, clinical severity scales, quality of life (QoL), re-intervention rates, and functional walking ability assessed by any validated walking impairment questionnaire. We presented the outcomes at two time points: two years or less after the original revascularisation (short term) and more than two years after the original revascularisation (long term). DATA COLLECTION AND ANALYSIS We used standard Cochrane methodological procedures. We used the Cochrane RoB 1 tool to assess the risk of bias for RCTs and GRADE to assess the certainty of evidence. We performed meta-analysis when appropriate. MAIN RESULTS We included three studies (1092 participants) that compared DUS plus pulse palpation and arterial pressure index (ABI or TBI) versus pulse palpation and arterial pressure index (ABI or TBI) for surveillance of lower limb revascularisation with bypass. One study each was conducted in Sweden and Finland, and the third study was conducted in the UK and Europe. The studies did not report adverse events resulting from DUS surveillance, functional walking ability, or clinical severity scales. No study assessed surveillance with DUS scanning after angioplasty or stenting, or both. We downgraded the certainty of evidence for risk of bias and imprecision. Duplex ultrasound plus pulse palpation and arterial pressure index (ABI or TBI) versus pulse palpation plus arterial pressure index (ABI or TBI) (short-term time point) In the short term, DUS surveillance may lead to little or no difference in limb salvage rate (risk ratio (RR) 0.84, 95% confidence interval (CI) 0.49 to 1.45; I² = 93%; 2 studies, 936 participants; low-certainty evidence) and vein graft secondary patency (RR 0.92, 95% CI 0.67 to 1.26; I² = 57%; 3 studies, 1092 participants; low-certainty evidence). DUS may lead to little or no difference in all-cause mortality (RR 1.11, 95% CI 0.70 to 1.74; 1 study, 594 participants; low-certainty evidence). There was no clear difference in QoL as assessed by the 36-item Short Form Health Survey (SF-36) physical score (mean difference (MD) 2 higher, 95% CI 2.59 lower to 6.59 higher; 1 study, 594 participants; low-certainty evidence); the SF-36 mental score (MD 3 higher, 95% CI 0.38 lower to 6.38 higher; 1 study, 594 participants; low-certainty evidence); or the EQ-5D utility score (MD 0.02 higher, 95% CI 0.03 lower to 0.07 higher; 1 study, 594 participants; low-certainty evidence). DUS may increase re-intervention rates when considered any therapeutic intervention (RR 1.38, 95% CI 1.05 to 1.81; 3 studies, 1092 participants; low-certainty evidence) or angiogram procedures (RR 1.53, 95% CI 1.12 to 2.08; 3 studies, 1092 participants; low-certainty evidence). Duplex ultrasound plus pulse palpation and arterial pressure index (ABI or TBI) versus pulse palpation plus arterial pressure index (ABI or TBI) (long-term time point) One study reported data after two years, but provided only vessel or graft secondary patency data. DUS may lead to little or no difference in vessel or graft secondary patency (RR 0.83, 95% CI 0.19 to 3.51; 1 study, 156 participants; low-certainty evidence). Other outcomes of interest were not reported at the long-term time point. AUTHORS' CONCLUSIONS Based on low certainty evidence, we found no clear difference between DUS and standard surveillance in preventing limb amputation, morbidity, and mortality after lower limb revascularisation. We found no studies on DUS surveillance after angioplasty or stenting (or both), only studies on bypass grafting. High-quality RCTs should be performed to better inform the best medical surveillance of lower limb revascularisation that may reduce the burden of peripheral arterial disease.

Abstract
AIM To analyze the associations between the Walking Impairment Questionnaire (WIQ) and 6-minute walk test (6MWT) in absolute or relative performance in patients with peripheral artery disease (PAD) and different degrees of claudication symptoms. METHODS Two hundred and sixty-seven patients with PAD and claudication symptoms participated in the study. All patients underwent 6MWT and WIQ tests. Patients were divided into tertile groups according to their 6MWT performance (1st tertile = severe, 2nd = moderate, 3rd = mild). Multiple linear regression was performed to investigate the association between WIQ scores and the achievement of expected performance in the 6MWT. RESULTS Claudication onset distance and time, total walking distance, and the percentage of the predicted values had a significant weak correlation ( P < 0.01) with WIQ scores (distance, speed, and stair-climbing capacity). The correlations for almost all variables were slightly higher in the 1st tertile compared with the 2nd and 3rd tertiles (i.e. WIQ-distance and Claudication onset time, r = 0.25 and 0.12, WIQ-distance and Claudication onset distance, r = 0.34 and 0.18; WIQ-distance and total walking distance, r = 0.23 and 0.18, respectively). Multilinear regression confirmed a slightly superior relationship in the 1st tertile compared with the 2nd tertile (i.e. WIQ-distance and Claudication onset time, R2 = 0.24 and R2 = 0.01; WIQ-distance and Claudication onset distance, R2 = 0.25 and R2 = 0.03, respectively). CONCLUSIONS WIQ is weakly associated with absolute and relative 6MWT performance in patients with PAD. Despite slightly better correlations in patients with severe claudication symptoms, WIQ scores must be used with care as a surrogate marker of 6MWT performance in this group.

Use of the Walking Impairment Questionnaire and Walking Estimated-Limitation Calculated by History questionnaire to detect maximal walking distance equal to or lower than 250 m in patients with lower extremity arterial disease. Front Cardiovasc Med 2023; 10:968213. [PMID: 37025694 PMCID: PMC10072320 DOI: 10.3389/fcvm.2023.968213] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2022] [Accepted: 02/06/2023] [Indexed: 04/08/2023] Open
Abstract
Objective The objective was to assess the accuracy and optimal threshold of the Walking Impairment Questionnaire (WIQ) and the Walking Estimated-Limitation Calculated by History (WELCH) questionnaire in identifying patients with a maximal walking distance (MWD) below or equal to 250 m. Methods This retrospective study screened 388 consecutive patients with suspected symptomatic lower extremity arterial disease (LEAD). Collected data included the patient's history, resting ankle-brachial index, WIQ, and WELCH. MWD was assessed with a treadmill test at 2 mph (3.2 km/h) with a 10% grade. An optimized threshold for detection of MWD ≤ 250 m was determined for each questionnaire via receiver operating characteristic (ROC) curves. Subsequently, multivariate analysis was performed to build a new simple score to detect MWD ≤ 250 m. Results The study included 297 patients (63 ± 10 years old). With a threshold of ≤ 64%, the WIQ predicted MWD ≤ 250 m with an accuracy of 71.4% (66.2, 76.5%). With a threshold of ≤ 22, the WELCH predicted a treadmill walking distance of ≤ 250 m with an accuracy of 68.7% (63.4, 74.0%). A new score with only four "yes or no" questions had an accuracy of 71.4% (66.3, 76.6%). Items on this new score consisted of the level of difficulty of walking 1 block, declared maximum walking distance, usual walking speed, and maximum duration of slow walking. Conclusion A WIQ score ≤ 64% and a WELCH score ≤ 22 help to predict a walking distance of ≤ 250 m in a treadmill test at 2 mph (3.2 km/h) with a 10% grade. A 4-item score could be used for rapid evaluation of walking distance among patients with LEAD, but the validity of this 4-item score requires further confirmation studies.

Abstract
ObjectiveThe aim of this study is to compare the quality-of-life (QOL) outcomes and the tibio-pedal arterial pressure post-endovascular intervention.BackgroundPhysiological assessment of peripheral arterial lesions is infrequently performed during endovascular interventions.Materials and methodsWe retrospectively reviewed all 343 patients with intermittent claudication who underwent an endovascular intervention via tibio-pedal artery access from October 2018 to May 2021. The baseline and post-intervention tibio-pedal arterial pressures from the pedal sheaths were measured. QOL was assessed using a pre-validated Walking Impairment Questionnaire (WIQ) score before and at 30-day after intervention. We compared the baseline tibio-pedal arterial pressure, post-intervention tibio-pedal arterial pressure, delta pressure (post-intervention minus baseline), baseline WIQ scores, 30-day WIQ scores, and delta score (30-day minus baseline).ResultsAll 343 patients had successful tibio-pedal accesses. The average tibio-pedal arterial pressure at baseline was 87.0 ± 1.8 mmHg vs. 135.5 ± 1.7 mmHg post-intervention (p < 0.001). Average baseline and 30-day WIQ scores were summation (99.8 ± 3.3 vs. 115.0 ± 3.1, p < 0.001), walking distance (35.7 ± 1.3 vs. 42.5 ± 1.3, p < 0.001), walking speed (21.1 ± 0.9 vs. 23.6 ± 0.8, p = 0.036), stair climbing (4.7 ± 1.4 vs. 24.2 ± 1.4, p = 0.019), and symptoms (18.8 ± 0.2 vs. 20.1 ± 0.2, p < 0.001), respectively. When comparing the increased post-intervention tibio-pedal arterial pressure <60 mmHg vs. ≥60 mmHg, the average delta WIQ scores were all significantly improved with summation (10.0 ± 3.9 to 25.8 ± 5.5, p = 0.01), walking distance (4.1 ± 1.7 to 9.8 ± 2.5, p = 0.02), walking speed (1.5 ± 1.1 to 4.3 ± 1.5, p = 0.02), stair climbing (2.3 ± 1.8 to 9.4 ± 2.5, p = 0.02), and symptoms (1.0 ± 0.3 to 1.8 ± 0.4, p = 0.04), respectively.ConclusionIncreasing the post-intervention tibio-pedal arterial pressure by 60 mmHg can enhance QOL as suggested by improvement of WIQ scores.

Abstract
This pilot randomised controlled trial aims to assess the feasibility and acceptability of a 12-week home-based telehealth exercise and behavioural intervention delivered in socioeconomically deprived patients with peripheral artery disease (PAD). The study will also determine the preliminary effectiveness of the intervention for improving clinical and health outcomes. Sixty patients with PAD who meet the inclusion criteria will be recruited from outpatient clinic at the Freeman Hospital, United Kingdom. The intervention group will undergo telehealth behaviour intervention performed 3 times per week over 3 months. This program will comprise a home-based exercise (twice a week) and an individual lifestyle program (once per week). The control group will receive general health recommendations and advice to perform unsupervised walking training. The primary outcome will be feasibility and acceptability outcomes. The secondary outcomes will be objective and subjective function capacity, quality of life, dietary quality, physical activity levels, sleep pattern, alcohol and tobacco use, mental wellbeing, and patients’ activation. This pilot study will provide preliminary evidence of the feasibility, acceptability and effectiveness of home-based telehealth exercise and behavioural intervention delivered in socioeconomically deprived patients with PAD. In addition, the variance of the key health outcomes of this pilot study will be used to inform the sample size calculation for a future fully powered, multicentre randomized clinical trial.

Abstract
Chronic limb-threatening ischemia (CLTI) causes significant morbidity with profound negative effects on health-related quality of life. As the prevalence of peripheral artery disease and diabetes continue to rise in our aging population, the public health impact of CLTI has escalated. Patient-reported outcome measures (PROMs) have become common and important measures for clinical evaluation in both clinical care and research. PROMs are important for the measurement of clinical effectiveness and cost effectiveness and for shared decision-making on treatment options. However, the PROMs used to describe the experience of patients with CLTI are heterogeneous, incomplete, and lack specific applicability to the underlying disease processes and diverse populations. For example, certain PROMs exist for patients with extremity wounds, and other PROMs exist for patients with pain, and still others exist for patients with vascular disease. Despite this multiplicity of tools, no single PROM encompasses all of the components necessary to describe the experiences of patients with CLTI. This significant unmet need is evident from both published reports and contemporary large-scale clinical trials in the field. In this systematic review, we review the current use of PROMs for patients with CLTI in clinical practice and in research trials and highlight the gaps that need to be addressed to develop a unifying PROM instrument for CLTI.

WalkingPad protocol: a randomized clinical trial of behavioral and motivational intervention added to smartphone-enabled supervised home-based exercise in patients with peripheral arterial disease and intermittent claudication. Trials 2022; 23:326. [PMID: 35436974 PMCID: PMC9014283 DOI: 10.1186/s13063-022-06279-9] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2021] [Accepted: 04/04/2022] [Indexed: 12/24/2022] Open
Abstract
Background Physical exercise is a first-line treatment for peripheral arterial disease (PAD) and intermittent claudication (IC) reducing pain and increasing the distances walked. Home-based exercise therapy (HBET) has the advantage of reaching a higher number of patients and increasing adherence to physical exercise as it is performed in the patient’s residential area and does not have the time, cost, and access restrictions of supervised exercise therapy (SET) implemented in a clinical setting. Even so, rates of adherence to physical exercise are relatively low, and therefore, m-health tools are promising in increasing motivation to behavior change and adherence to physical exercise. A built-in virtual assistant is a patient-focused tool available in a mobile interface, providing a variety of functions including health education, motivation, and implementation of behavior change techniques. Methods This is a single-center, prospective, three-arm, single-blind, randomized, controlled, superior clinical trial with stratified and blocked random allocation. Three hundred participants with PAD and IC will be recruited from an Angiology and Vascular Surgery Department, Centro Hospitalar Universitário Porto (CHUPorto), Porto, Portugal. All patients will receive the same medical care recommended by current guidelines. Participants in all three groups will receive a personalized prescription for an HBET program and a behavioral change and motivational intervention. Participants in experimental groups 1 and 2 will receive a smartphone with the WalkingPad app to monitor exercise sessions. Experimental group 2 WalkingPad app will have a built-in virtual assistant that will promote behavioral change and provide motivational support. Participants allocated to the active control group will not receive the m-health tool, but a practice diary to encourage monitoring. The program will last for 6 months with three evaluation moments (baseline, 3, and 6 months). The primary outcome will be the change in distances walked (maximal and pain-free) from baseline to 3 and 6 months. Secondary outcomes will be changes in quality of life, patients’ perception of resistance, and walking speed. Discussion This study will allow measuring the effectiveness of an m-health tool in increasing motivation for behavior change and adherence to an HBET program in patients with PAD. The superiority of experimental group 2 in the primary and secondary outcomes will indicate that the virtual assistant is effective for motivating behavioral change and encouraging the practice and adherence to physical exercise. The use of m-health tools and virtual health assistants can potentially fill a gap in the access and quality of health services and information, reducing the burden on the health system and promoting self-management and self-care in chronic illness.

Abstract
Objectives Patient-reported outcome measures can facilitate the assessment of walking impairment in peripheral artery disease patients with intermittent claudication in clinical trials and practice. The aim of this study was to test the psychometric properties of the German version of the 'Walking Estimated-Limitation Calculated by History' (WELCH) questionnaire. Methods The assessed properties included feasibility, test-retest reliability, construct validity (i.e., convergent, divergent and known-groups validity) and responsiveness using classic psychometric methods. Psychometric properties were tested as part of a randomized controlled home-based exercise trial for patients with symptomatic peripheral artery disease at Fontaine stage IIA/B. Results Analyses were conducted in subgroups of 1,696 patients at baseline and 1,233 patients at 12-month follow-up (i.e., post-intervention) who completed the WELCH along with a battery of other self-report measures. The WELCH did not exhibit relevant floor or ceiling effects (< 15% achieved lowest or highest possible scores), showed evidence for good test-retest reliability (ICC = .81, 95% CI [.71-.88]) and was found to be well suited for self-completion by patients (< 5% missing data per item). WELCH scores showed moderate to strong correlations with related measures of walking impairment at both time points (Walking Impairment Questionnaire: r = .56 - .74; VascuQoL-25 activity subscale: r = .61 - .66) and distinguished well among patients with poor and high quality of life when adjusting for confounders (t = 13.67, p < .001, d = .96). Adequate divergent validity was indicated by a weaker correlation between the WELCH and general anxiety at both time points (GAD-7: r = - .14 to - .22). The WELCH improved by 6.61 points (SD = 17.04, 95% CI [5.13-8.10], d = 0.39) in response to exercise treatment and was able to identify large clinically important improvements observed on the walking distance (AUC = .78, 95% CI [.71-.84]) and speed subscales (AUC = .77, 95% CI [.68-.86]) of the Walking Impairment Questionnaire. Conclusions The WELCH is considered a feasible, reliable and valid patient-reported outcome measure for the measurement of walking impairment in patients with peripheral artery disease. The WELCH showed evidence for responsiveness to changes in walking impairment, yet further studies are warranted to conclusively determine the WELCH's ability to detect intervention effects.

Abstract
BACKGROUND The mechanisms underlying functional impairments in symptomatic PAD patients are controversial and poorly understood. Endothelial dysfunction and arterial stiffness have been proposed as potential mechanisms related to functional impairment in symptomatic PAD patients, however, more studies are needed to confirm these associations. OBJECTIVE To analyze the association between vascular function and walking impairment in patients with peripheral arterial disease (PAD) and symptoms of claudication. METHODS This was a cross-sectional study that included 68 patients with symptomatic PAD. All patients underwent an objective (Six-minute walk test [6MWT], 4-meter walk test) and a subjective (Walking Impairment Questionnaire [WIQ]) measurement of walking impairment. Vascular parameters measured were pulse-wave velocity (PWV) and flow-mediated dilation (FMD). Multiple linear regression was performed to investigate the association among walking impairment variables with vascular function parameters. RESULTS No significant associations between the claudication onset distance (PWV: b=.060, P = 0.842; FMD: b=-.192, P = 0.456), 6MWT (PWV: b=.007, P = 0..975; FMD: b=.090, P = 0.725), WIQ distance (PWV: b=.337, P = 0.117; FMD: b=-.025, P = 0.895) WIQ speed (PWV: b=.320, P = 0.181; FMD: b=-.028, P = 0.497), WIQ stairs (PWV: b=.256, P = 0.204; FMD: b=-.228, P = 0.230), 4-meter usual walk (PWV: b=-.421, P = 0.107; FMD: b=-.338, P = 0.112), 4-meter fast walk (PWV: b=-.496, P = 0.063; FMD: b=-.371, P = 0.086) and vascular function were found. CONCLUSIONS In symptomatic PAD patients, vascular function is not associated to walking impairment, even when adjusting for comorbid conditions and diabetes.

Abstract
Background Lumbar spinal stenosis (LSS) and peripheral arterial disease (PAD) are two distinct conditions characterized by similar symptoms including leg pain and walking limitations due to claudication. Differentiation between both origins can be difficult and characteristics such as symptom manifestations, time to relief in rest position and pain localization should be considered when determining diagnosis and the treatment plan. The objectives of this study were to compare changes in walking time to symptom change during treadmill tests and self-reported outcomes measures related to claudication, kinesophobia and global health between individuals with LSS, PAD and non-specific low back pain (nLBP). Method Fifty-five patients (23 with LSS, 14 with PAD and 18 with nLBP) were recruited from May 2018 to March 2020 to complete a treadmill walking test involving two 5-min walking tasks (Upright and Forward Leaning Trunk (FLT) Walking tasks). The speed was set at 1.9 km/h (1.2 mph), and each task was followed by a 5-min rest period. Walking time to symptom change and Total walking time were recorded during each walking task. Patients were asked to complete four questionnaires related to the impact of claudication, walking impairment, kinesiophobia and global health. One-way ANOVAs were performed to compare walking time difference from the Upright to the FLT walking tasks and to compare questionnaires results between groups. Results One-way ANOVAs showed a significant difference between groups regarding difference in Walking time to symptom change between both tasks (F = 4.12, p = 0.022). The LSS group improved its Walking time to symptom change from the Upright to the FLT walking tasks more than the PAD (p = 0.34) and the nLBP group (p = 0.12). The nLBP group was less impacted by claudication and less impaired during walking compared to the LSS and PAD groups (ps < 0.001). The nLBP group also had less kinesiophobia than the LSS one (p < 0.001), but was similar to the PAD group. The global health rating was not statistically different between groups (p = 0.118). Conclusion The test was able to distinguish neurogenic from vascular or nLBP related claudication. However, further studies are needed to validate this new treadmill walking test.

Abstract
Background: A significant consequence of peripheral arterial disease (PAD) is an impaired functional capacity and deteriorated quality of life. Therefore, our study aimed to investigate the usefulness of a symptom questionnaire and walk tests for the determination of the functional capacity of patients with intermittent claudication. Patients and methods: The study included 53 patients (38 males) with stable claudication distance (50-300m). A detailed history and physical examination, ankle-brachial index (ABI), treadmill exercise test, and 6-minute walk test were performed and compared to walking impairment questionnaire (WIQ). Results: Claudication distance reported from patients' history and 6-minute walk test were significantly correlated with ABI (p=0.033, p=0.044). There were no significant correlations between ABI and treadmill walk test or WIQ. Results of WIQ were significantly correlated with the history and the most of performed walk tests: treadmill initial and maximal claudication distance (p=0.004 and 0.012, respectively) and 6-minute walk test (p=0.026). 6-minute walk test was correlated with maximal claudication distance of treadmill (p=0.018), but not with an initial claudication distance. Conclusions: The validity of WIQ is comparable to walk tests and represents the useful technique for the investigation of the functional capacity of patients with PAD. A self-report based on WIQ enables a longer period of observation. It should be routinely used as a basic diagnostic tool for the estimation of the functional capacity of PAD patients with stable intermittent claudication.

Abstract
OBJECTIVE The Tack Endovascular System (Intact Vascular, Wayne, Pa) combines low-metallic content with focal delivery to seal areas of dissection associated with balloon angioplasty. The device system is designed to treat vascular dissections in the superficial femoral and proximal popliteal arteries. Tack implants exert low radial force and are associated with minimal metal burden, which reduces the mechanical stress on the arterial wall in treating dissections after balloon angioplasty. This study investigated the safety and effectiveness of the Tack Endovascular System in patients with dissections after drug-coated balloon (DCB) angioplasty. METHODS The Tack Optimized Balloon Angioplasty III (TOBA III) study is a prospective, multicenter, single-arm study in which patients who underwent percutaneous transluminal angioplasty with the Medtronic IN.PACT Admiral DCB (Medtronic, Dublin, Ireland) and experienced dissection after angioplasty were treated with Tack implants. The primary end points were freedom from major adverse events at 30 days and primary patency at 12 months. RESULTS A total of 201 patients were enrolled in the trial, 169 with standard-length lesions (≥20 mm and ≤150 mm) and 32 with long-length lesions (>150 mm and ≤250 mm). Safety and effectiveness results were favorable compared with historical benchmarks at 12 months in the standard-lesion cohort. Notably, patients in the standard-lesion cohort experienced 95.0% primary patency, 97.5% freedom from clinically driven target lesion revascularization, 100% freedom from amputation, and 100% survival at 12 months (P < .0001). Primary patency in long-lesion patients was 89.3%, freedom from clinically driven target lesion revascularization was 96.8%, and freedom from amputation was 100% at 12 months. Device success was achieved in 95.8% (182/190) and 97.7% (43/44) of devices deployed into standard-lesion and long-lesion patients, respectively. Procedural success was 99.4% (168/169) and 100% (44/44) in the standard-lesion and long-lesion cohorts, respectively, with only one bailout stent placed in the entire population. CONCLUSIONS The Tack Endovascular System is a safe and effective treatment option for patients with dissections after angioplasty in the superficial femoral and proximal popliteal arteries, with high patency, low rates of secondary intervention, and low incidence of bailout stenting when it is used in combination with DCB.

Abstract
OBJECTIVE No vascular implant is commercially available in the United States to treat post-angioplasty dissections in below-the-knee (BTK) arteries. The Tack Endovascular System (Intact Vascular, Wayne, Pa) is purpose-built to repair postpercutaneous transluminal angioplasty (PTA) BTK dissections. A trial was conducted to investigate the safety and efficacy of the first-of-a-kind implantable BTK device to treat post-PTA dissections in the setting of critical limb ischemia. METHODS The present prospective, single-arm, multicenter study evaluated the Tack Endovascular System for treating post-PTA dissections in the mid/distal popliteal, tibial, and peroneal arteries. The primary safety endpoint was major adverse limb events (MALE) plus perioperative death (POD), assessed at 30 days after the index procedure. The primary efficacy endpoint was a composite of MALE at 6 months and POD. The unpowered secondary endpoint was primary patency at 6 months. With no available on-label comparator, the primary endpoints of the present trial were determined using objective performance goals from a systematic literature search. The secondary endpoints included Tacked segment patency and target limb salvage at 6 months. The 6-month results are reported. RESULTS Of the 233 patients enrolled, 117 (50.2%) had Rutherford class 5 and 78 (33.5%) had Rutherford class 4. A total of 341 post-PTA dissections were treated. Each patient received at least one Tack implant, and 100% of the dissections resolved according to the angiographic core laboratory findings. The primary safety and efficacy endpoints were both met. The rate of MALE plus POD at 30 days was 1.3% (3 of 228) and freedom from MALE at 6 months plus POD at 30 days was 95.6% (196 of 205). The 6-month Tacked segment patency was 82.1% (247 of 301) and target limb salvage was 98.5% (202 of 205). The Kaplan-Meier freedom from clinically driven target lesion revascularization and amputation-free survival at 6 months was 92.0% and 95.7%, respectively. Rutherford improvement was reported in 79.4% (158 of 199). Most (90 of 122; 73.8%) preexisting wounds had healed or were improving. CONCLUSIONS The Tack Endovascular System is safe and effective for treating post-PTA BTK dissections through 6 months, with favorable rates of MALE plus POD, patency, clinically driven target lesion revascularization, limb salvage, and wound healing.

Abstract
Purpose: To report the 12-month safety and efficacy outcomes of the investigational device exemption trial evaluating an implantable below-the-knee (BTK) dissection repair device. Materials and Methods: The prospective, multicenter, single-arm Tack-Optimized Balloon Angioplasty (TOBA) II BTK study (ClinicalTrials.gov identifier NCT02942966) evaluated the Tack Endovascular System in the BTK arteries vs objective performance goals derived from a systematic review of BTK angioplasty literature. Patients presenting with Rutherford category 3-5 ischemia were eligible and were enrolled during the procedure if angioplasty resulted in dissection(s) of the BTK arteries. Between February 2017 and December 2018, the study enrolled 233 patients (mean age 74.4±10.0 years; 157 men). Most lesions (93.8%) were de novo; almost half (118/248, 47.6%) were total occlusions. Mean target lesion length was 80±49 mm. Moderate to severe calcium was present in 89 (35.8%) lesions. The 30-day primary safety endpoint was a composite of major adverse limb events (MALE) and all-cause perioperative death (POD). The primary efficacy endpoint was a composite of MALE at 6 months and 30-day POD. These safety and efficacy endpoints were assessed at 12 months as observational endpoints along with amputation-free survival (AFS), freedom from clinically-driven target lesion revascularization (CD-TLR), vessel patency, and changes from baseline in clinical and quality of life measures. Results: All patients had post-PTA dissection and received at least 1 Tack implant (range 1 to 16). The angiographic core laboratory noted successful resolution of 100% of the 341 treated dissections. At 12 months, 93.4% (170/182) of patients remained free of the composite endpoint of MALE + POD. Tacked segment patency was 81.3% and limb salvage was 96.8% at 12 months; freedom from CD-TLR and AFS were 83.1% and 89.3%, respectively. Sustained Rutherford category improvement was reported in 82.4% of evaluated patients, with 62.4% improving ≥3 categories (p<0.001). Ninety of 124 index wounds (72.5%) healed or improved. Conclusion: The Tack Endovascular System is safe and effective in the treatment of post-angioplasty BTK dissections. Twelve-month outcome data from the TOBA II BTK study demonstrate high rates of patency, limb salvage, and wound healing.

Abstract
INTRODUCTION Peripheral artery disease (PAD) is the third most prevalent cardiovascular disease worldwide, with smoking and diabetes being the strongest risk factors. The most prominent symptom is leg pain while walking, known as intermittent claudication. To improve mobility, first-line treatment for intermittent claudication is supervised exercise programmes, but these remain largely unavailable and economically impractical, which has led to the development of structured home-based exercise programmes. This trial aims to determine the effectiveness and cost advantage of TeGeCoach, a 12-month long home-based exercise programme, compared with usual care of PAD. It is hypothesised that TeGeCoach improves walking impairment and lowers the need of health care resources that are spent on patients with PAD. METHODS AND ANALYSIS The investigators conduct a prospective, pragmatic randomised controlled clinical trial in a health insurance setting. 1760 patients diagnosed with PAD at Fontaine stage II are randomly assigned to either TeGeCoach or care-as-usual. TeGeCoach consists of telemonitored intermittent walking exercise with medical supervision by a physician and telephone health coaching. Participants allocated to the usual care group receive information leaflets and can access supervised exercise programmes, physical therapy and a variety of programmes for promoting a healthy lifestyle. The primary outcome is patient reported walking ability based on the Walking Impairment Questionnaire. Secondary outcome measures include quality of life, health literacy and health behaviour. Claims data are used to collect total health care costs, healthcare resource use and (severe) adverse events. Outcomes are measured at baseline, 12 and 24 months. ETHICS AND DISSEMINATION Ethical approval has been obtained from the Medical Association Hamburg. Findings are disseminated through peer-reviewed journals, reports to the funding body, conference presentations and media press releases. Data from this trial are made available to the public and researchers upon reasonable request.NCT03496948 (www.clinicaltrials.gov), Pre-results.

Abstract
Summary: Background: Symptomatic peripheral arterial disease (intermittent claudication) is a major cause of disability and mobility loss in older men and women and thus has a significant negative impact on the patients’ quality of life. Both surgical and endovascular revascularization procedures and noninvasive medical therapies, such as supervised training and drug treatment, can improve walking capacity. Cilostazol is the only drug having a class I (level of evidence A) recommendation for the treatment of intermittent claudication (IC). The aim of this study was to evaluate the effect of three-month cilostazol treatment on the health-related quality of life and on the lower limb functional capacity in patients with IC in the clinical practice. Patients and methods: The study was a multicenter, non-interventional trial, performed in Hungary in 2018. 812 PAD patients (Fontaine II stage, mean age: 67.17 years, male/female: 58.25/41.75 %) were enrolled, who received cilostazol (50 or 100 mg b.i.d.) for 3 months. 802 patients completed the study. Quality of life was evaluated with the EQ-5D-3L questionnaire functional capacity with the WELCH (Walking Estimated-Limitation Calculated by History) questionnaire. Pain-free and maximal walking distance, ankle-brachial index (ABI) were measured at baseline and after 3-month treatment. Results: Upon conclusion of the study, the EQ-5D-3L index improved (baseline: –0.46 ± 0.22, 3rd month: –0.26 ± 0.18; p < 0.0001) and there was a significant increase in the WELCH score as well (19 ± 14, 31 ± 18; respectively, p < 0.0001). Both pain-free and maximal walking distance improved significantly by 54.52 % (median: 53.85 %) and 42.5 % (median: 34.68 %); respectively (p < 0.001). Adverse events occurred in 10 patients, 1 patient stopped cilostazol treatment because of side effects. Conclusions: Three months cilostazol treatment significantly improved quality of life and lower limb functional capacity in patients with intermittent claudication. The WELCH questionnaire is a useful tool for the evaluation of intermittent claudication treatment in the clinical practice.

Abstract
OBJECTIVE Exercise training has multiple beneficial effects in patients with arteriosclerotic diseases; however, the exact underlying mechanisms of the effects are not completely understood. This study aimed to evaluate the effectiveness of a supervised exercise program in improving gait parameters, including the variability and walking performance of lower limb movements, in patients with peripheral artery disease (PAD) and intermittent claudication (IC). METHODS Sixteen patients with a history of PAD and IC were recruited for this study, and they completed a 3-month supervised bicycle exercise program. The ankle-brachial index and responses to quality of life (QOL) questionnaires were evaluated. Near-infrared spectroscopy was also performed to determine the hemoglobin oxygen saturation in the calf. Patients' kinematics and dynamics, including joint range of motion and muscle tension, were evaluated using an optical motion capture system. Computed tomography images of each muscle were assessed by manual outlining. Data were collected before and after the supervised bicycle exercise program, and differences were analyzed. RESULTS Significant differences were not found in step length, ankle-brachial index, and hemoglobin oxygen saturation before and after the supervised bicycle exercise program; however, IC distance (P = .034), maximum walking distance (P = .006), and all QOL questionnaire scores (P < .001) showed significant improvement. Hip range of motion (P = .035), maximum hip joint torque (right, P = .031; left, P = .044), maximum tension of the gluteus maximus muscle (right, P = .044; left, P = .042), and maximum hip joint work (right, P = .048; left, P = .043) also significantly decreased bilaterally. Computed tomography images showed a significant increase in the cross-sectional area of the abdominal, trunk, and thigh muscles but not in that of the lower leg muscles after the supervised exercise program intervention. CONCLUSIONS In this study, bicycle exercise training improved the QOL and walking distance and decreased hip movement. The results showed that bicycling might be as useful as walking in patients with PAD.

Abstract
Supplemental Digital Content is available in the text. Background— Randomized controlled trials have reported favorable 1-year outcomes with drug-coated balloons (DCBs) for the treatment of symptomatic peripheral arterial disease when compared with standard percutaneous transluminal angioplasty (PTA). Evidence remains limited on the durability of the treatment effect with DCBs in the longer term. Methods and Results— IN.PACT SFA is a single-blind, randomized trial (Randomized Trial of IN.PACT Admiral Paclitaxel-Coated Percutaneous Transluminal Angioplasty [PTA] Balloon Catheter vs Standard PTA for the Treatment of Atherosclerotic Lesions in the Superficial Femoral Artery [SFA] and/or Proximal Popliteal Artery [PPA]) that enrolled 331 patients with symptomatic (Rutherford 2–4) femoropopliteal lesions up to 18 cm in length. Patients were randomized 2:1 to receive treatment with DCB or PTA. The 36-month assessments included primary patency, freedom from clinically driven target lesion revascularization, major adverse events, and functional outcomes. At 36 months, primary patency remained significantly higher among patients treated with DCB compared with PTA (69.5% versus 45.1%; log rank P<0.001). The rates of clinically driven target lesion revascularization were 15.2% and 31.1% (P=0.002) for the DCB and PTA groups, respectively. Functional outcomes were similarly improved between treatment groups even though subjects in the DCB group required significantly fewer reinterventions versus those in the PTA group (P<0.001 for target lesion revascularization, P=0.001 for target vessel revascularization). There were no device- or procedure-related deaths as adjudicated by an independent Clinical Events Committee. Conclusions— Three-year results demonstrate a durable and superior treatment effect among patients treated with DCB versus standard PTA, with significantly higher primary patency and lower clinically driven target lesion revascularization, resulting in similar functional improvements with reduced need for repeat interventions. Clinical Trial Registration— URL: http://www.clinicaltrials.gov. Unique identifiers: NCT01175850 for IN.PACT SFA phase I in the European Union and NCT01566461 for IN.PACT SFA phase II in the United States.

Abstract
Due to the paucity of independent trials, practical guidelines for the diagnosis and treatment of peripheral arterial disease (PAD) contain several recommendations developed by expert consensus. Furthermore, there is a lack of commonly defined quality indicators and valid data on real world treatment. Therefore, it remains challenging to scrutinize if treatment reality is conforming to guideline recommendations. This article aims to give a short overview on existing guideline recommendations. It further aims to introduce the multistage multimethodological IDOMENEO study, utilizing primary registry data (GermanVasc) and health insurance claims data (BARMER) in PAD treatment.

Abstract
OBJECTIVE Determining the maximum walking time (MWT) using the treadmill test is the gold standard method for evaluating walking capacity and treatment effect in patients with peripheral arterial disease (PAD). However, self reported functional disability is important when assessing quality of life. Changes in the Walking Estimated Limitation Calculated by History (WELCH) questionnaire scores were compared with the MWT. METHODS A cross sectional study was performed in patients with intermittent claudication. The treadmill test (3.2 km/h; 10% gradient) and WELCH questionnaire were administered to all patients for objective evaluation of walking capacity. Given the log normal distribution of these parameters in patients with PAD, a log transformation was applied to the WELCH score (LnW) and maximum walking time (LnT). The responsiveness of the WELCH score was determined using mean changes and correlation coefficients of LnW and LnT changes. The effect of time on the "estimated minus real" (E - R) changes (LnW - change minus LnT - change) was assessed after categorisation of patients into various test-retest intervals. Patients who underwent lower limb revascularisation between the two tests and those who underwent medical treatment only were analysed. RESULTS Correlation coefficients between LnW and LnT for tests 1 and 2 were r = 0.514 and r = 0.503, respectively (p < .001, for both). Correlation for LnW change vs. LnT change was 0.384 (p < .001). E - R was positive only early after surgery. E - R was negative for all test-retest intervals >1 year in revascularised and non-revascularised patients. CONCLUSION Changes in WELCH scores correlated with changes observed on the treadmill in patients with intermittent claudication. For long test-retest intervals, WELCH changes tended to overestimate the worsening of walking impairment as compared with the measured difference observed in both revascularised and non-revascularised patients. A shortlived "honeymoon" (overestimation of the benefit for the shortest test-retest interval) was observed only in revascularised patients.

Fish Oil Increases Specialized Pro-resolving Lipid Mediators in PAD (The OMEGA-PAD II Trial). J Surg Res 2019; 238:164-174.

Abstract
BACKGROUND N-3 polyunsaturated fatty acid (PUFA) supplementation has been associated with reduced mortality and inflammation in patients with cardiovascular disease. There are limited data on the effects of n-3 PUFA supplementation in patients with peripheral artery disease (PAD). MATERIALS AND METHODS The OMEGA-PAD II trial was a double-blinded, randomized, placebo-controlled trial to assess the effect of 3 mo of high-dose oral n-3 PUFA supplementation on inflammation, endothelial function, and walking ability in patients with PAD. RESULTS Twenty-four patients with claudication received 4.4 g/d of fish oil or placebo for 3 mo. Outcomes measured included high-sensitivity C-reactive protein levels, the omega-3 index, endothelial function as measured via flow-mediated vasodilation, walking impairment questionnaire, and a 6-min walk test. Plasma levels of specialized pro-resolving lipid mediators (SPMs) were measured by liquid-chromatography-tandem mass spectrometry. In patients treated with fish oil, the absolute mean omega-3 index significantly increased from baseline (fish oil: 7.2 ± 1.2%, P < 0.001; placebo: -0.4 ± 0.9%, P = 0.31; between-group P < 0.001). Furthermore, there were significant increases in several pathway markers of SPM biosynthesis, including several mono-hydroxyeicosapentaenoic acids and mono-hydroxydocosahexaenoic acids. We also observed significant increases in the SPM lipoxin A5 (fish oil: 0.57 ± 0.70 pg/mL, P = 0.05; placebo: 0.01 ± 0.38 pg/mL, P = 0.93; between-group P = 0.04) and resolvin E3 (fish oil: 154 ± 171 pg/mL, P = 0.04; placebo: 32 ± 54 pg/mL, P = 0.08; between-group P = 0.04). There were no significant changes in high-sensitivity C-reactive protein, flow-mediated vasodilation, walking impairment questionnaire, or 6-min walk test in the fish oil group. CONCLUSIONS Fish oil increases SPMs in plasma of patients with PAD. Further studies are required to determine whether these early changes translate to clinical improvements in patients with PAD.

Abstract
Thromboangiitis obliterans (TAO), also known as Buerger’s Disease, is an occlusive vasculitis linked with high morbidity and amputation risk. To date, TAO is deemed incurable due to the lack of a definitive treatment. The immune system and inflammation are proposed to play a central role in TAO pathogenesis. Due to their immunomodulatory effects, mesenchymal stromal cells (MSCs) are the subject of intense research for the treatment of a wide range of immune-mediated diseases. Thus far, local intramuscular injections of autologous or allogeneic MSCs have shown promising results in TAO. However, sequential intravenous allogeneic MSC administration has not yet been explored, which we hypothesized could exert a systemic anti-inflammatory effect in the vasculature and modulate the immune response. Here, we report the first case of a TAO patient at amputation risk treated with four sequential intravenous infusions of bone marrow-derived allogeneic MSCs from a healthy donor. Following administration, there was significant regression of foot skin ulcers and improvements in rest pain, Walking Impairment Questionnaire scores, and quality of life. Sixteen months after the infusion, the patient had not required any further amputations. This report highlights the potential of sequential allogeneic MSC infusions as an effective treatment for TAO, warranting further studies to compare this approach with the more conventionally used intramuscular MSC administration and other cell-based therapies.

Abstract
This article describes the development of the Claudication Symptom Instrument (CSI) and its measurement properties for evaluating the symptom experience of patients diagnosed with intermittent claudication (IC). We conducted semi-structured qualitative interviews with IC patients for item development and cognitive interviews in which patient comprehension of items was tested. We evaluated measurement properties using data collected and analyzed in the context of an observational comparative effectiveness study of IC treatments. Items measuring five symptom important to patients were developed and cognitively tested: Pain, Numbness, Heaviness, Cramping, and Tingling. Item means (higher means worse) ranged from 1.1 (Tingling) to 2.3 (Pain) (range: 0 'none' to 4 'extreme'). Rasch analysis yielded support for an overall score (χ2=26.5, df=20, p=0.15). The total CSI score differed by clinician-rated severity of mild versus moderate ( p<0.05), but not moderate versus severe. Re-administration of the CSI 5-10 days after baseline yielded an intra-class correlation coefficient of 0.86. Changes in CSI total score and VASCUQOL total score between baseline and 6 months post-treatment were correlated at -0.52 ( p<0.05). The CSI preliminarily meets accepted measurement standards for content validity, internal consistency and test-retest reliability, construct validity, and sensitivity for detecting change. Because of its high test-retest reliability, it may also be useful in clinical care with individual patients. It takes approximately 3 minutes to complete.

Abstract
Background Intermittent claudication (IC) is a common condition that causes pain in the lower limbs when walking and has been shown to severely impact the quality of life (QoL) of patients. The QoL is therefore often regarded as an important measure in clinical trials investigating intermittent claudication. To date, no consensus exits on the type of life questionnaire to be used. This review aims to examine the QoL questionnaires used in trials investigating peripheral arterial disease (PAD). Material and methods A systematic review of randomised clinical trials including a primary analysis of QoL via questionnaire was performed. Trials involving patients with diagnosed PAD were included (either clinically or by questionnaire). Any trial which had QoL as the primary outcome data was included with no limit being placed on the type of questionnaire used. Results The search yielded a total of 1845 articles of which 31 were deemed appropriate for inclusion in the review. In total, 14 different QoL questionnaires were used across 31 studies. Of the questionnaires 24.06% were missing at least one domain when reported in the results of the study. Mean standard deviation varied widely based on the domain reported, particularly within the SF36. Discussion Despite previous recommendations for Europewide standardisation of quality of life assessment, to date no such tool exists. This review demonstrated that a number of different questionnaires remain in use, that their completion is often inadequate and that further evidence-based guidelines on QoL assessment are required to guide future research.

Abstract
Background Physical activity is recommended for people with peripheral arterial disease (PAD), and can improve walking capacity and quality of life; and reduce pain, requirement for surgery and cardiovascular events. This trial will assess the efficacy of a brief behavioral counselling intervention delivered by allied health professionals to improve physical activity in people with PAD. Methods This is a multi-center randomised controlled trial in four cities across Australia. Participants (N = 200) will be recruited from specialist vascular clinics, general practitioners and research databases and randomised to either the control or intervention group. Both groups will receive usual medical care, a written PAD management information sheet including advice to walk, and four individualised contacts from a protocol-trained allied health professional over 3 months (weeks 1, 2, 6, 12). The control group will receive four 15-min telephone calls with general discussion about PAD symptoms and health and wellbeing. The intervention group will receive behavioral counselling via two 1-h face-to-face sessions and two 15-min telephone calls. The counselling is based on the 5A framework and will promote interval walking for 3 × 40 min/week. Assessments will be conducted at baseline, and 4, 12 and 24 months by staff blinded to participant allocation. Objectively assessed outcomes include physical activity (primary), sedentary behavior, lower limb body function, walking capacity, cardiorespiratory fitness, event-based claudication index, vascular interventions, clinical events, cardiovascular function, circulating markers, and anthropometric measures. Self-reported outcomes include physical activity and sedentary behavior, walking ability, pain severity, and health-related quality of life. Data will be analysed using an intention-to-treat approach. An economic evaluation will assess whether embedding the intervention into routine care would likely be value for money. A cost-effectiveness analysis will estimate change in cost per change in activity indicators due to the intervention, and a cost-utility analysis will assess change in cost per quality-adjusted life year. A full uncertainty analysis will be undertaken, including a value of information analysis, to evaluate the economic case for further research. Discussion This trial will evaluate the efficacy and cost-effectiveness of a brief behavioral counselling intervention for a common cardiovascular disease with significant burden.

Abstract
BACKGROUND Supervised treadmill exercise is the recommended therapy for peripheral arterial disease (PAD) patients with intermittent claudication (IC). However, most PAD patients do not exhibit typical symptoms of IC. The aim of the present study was to explore the efficacy and safety of intensive walking exercise in PAD patients with and without IC. METHODS The PubMed, Embase and Cochrane Library databases were systematically searched. Randomized controlled trials comparing the effects of intensive walking exercise with usual care in patients with PAD were included for systematic review and meta-analysis. RESULTS Eighteen trials with 1200 patients were eligible for the present analysis. Compared with usual care, intensive walking exercise significantly improved the maximal walking distance (MWD), pain-free walking distance, and the 6-min walking distance in patients with PAD (P < 0.00001 for all). Subgroup analyses indicated that a lesser improvement in MWD was observed in the subgroup with more diabetes patients, and that the subgroup with better baseline walking ability exhibited greater improvement in walking performance. In addition, similar improvements in walking performance were observed for exercise programs of different durations and modalities. No significant difference was found in adverse events between the intensive walking and usual care groups (relative risk 0.84; 95% confidence interval 0.51, 1.39; P = 0.50). CONCLUSIONS Regardless of exercise length and modality, regularly intensive walking exercise improves walking ability in PAD patients more than usual care. The presence of diabetes may attenuate the improvements in walking performance in patients with PAD following exercise.

Abstract
OBJECTIVES The literature increasingly demonstrates the importance of gait speed (GS) in the frailty assessment of patients aged 60 years and older. Conventional GS measurement, however, maybe contraindicated in settings such as trauma where the patient is temporarily immobilized. We devised a Walking Speed Questionnaire (WSQ) to allow assessment of preinjury baseline GS, in meters per second, in a self-reported manner, to overcome the inability to directly test the patients' walking speed. DESIGN Four questions comprise the WSQ, and were derived using previously published questionnaires and expert opinion of 6 physician-researchers. SETTING Four ambulatory clinics. PARTICIPANTS Ambulating individuals aged 60-95 (mean age, 73.2 ± 8.1 years, 86.1% female, n = 101). INTERVENTION Participants completed the WSQ and underwent GS measurement for comparison. ANALYSIS WSQ score correlation to true GS, receiver operating characteristics, and validation statistics were performed. RESULTS All 4 questions of the WSQ independently predicted true GS significantly (P < 0.001). The WSQ sufficiently predicted true GS with r = 0.696 and ρ = 0.717. CONCLUSIONS The WSQ is an effective tool for assessing baseline walking speed in patients aged 60 years and older in a self-reported manner. It permits gait screening in health care environments where conventional GS testing is contraindicated due to temporary immobilization and maybe used to provide baseline targets for goal-oriented post-trauma care. Given its ability to capture GS in patients who are unable to ambulate, it may open doors for frailty research in previously unattainable populations. LEVEL OF EVIDENCE Diagnostic Level II.

Abstract
CONTEXT AND OBJECTIVE Many clinical investigations use generic and/or specific questionnaires to obtain information about participants and patients. There is disagreement about whether the administration method can affect the results. The aim here was to determine whether, among patients with intermittent claudication (IC), there are differences in the Walking Impairment Questionnaire (WIQ) and European Quality of Life-5 Dimension (EQ-5D) scores with regard to: 1) the questionnaire administration method (self-administration versus face-to-face interview); and 2) the type of interviewer (vascular surgeon, VS, versus general practitioner, GP). DESIGN AND SETTING Cross-sectional observational multicenter epidemiological study carried out within the Spanish National Health Service. METHODS 1,641 evaluable patients with IC firstly completed the WIQ and EQ-5D questionnaires and then were interviewed by their doctor on the same day. Pearson correlations and Chi-square tests were used. RESULTS There was a strong correlation (r > 0.800; P < 0.001) between the two methods of administering the WIQ and EQ-5D questionnaires, and between the VS and GP groups. Likewise, there was a high level of concordance (P > 0.05) between the different dimensions of the WIQ-distance and EQ-5D (self-administration versus face-to-face) in the VS and GP groups. CONCLUSION There was no difference between the different methods of administering the WIQ and EQ-5D questionnaires, among the patients with IC. Similarly, the two types of interviewers (VS or GP) were equally valid. Therefore, it seems unnecessary to expend effort to administer these questionnaires by interview, in studies on IC.

Abstract
OBJECTIVE Prevalence of peripheral arterial disease is equal in men and women. However, women seem to suffer more from the burden of disease. Current studies on gender-related outcomes following supervised exercise therapy (SET) for intermittent claudication (IC) yield conflicting results. METHODS A follow-up analysis was performed on data from the 2010 Exercise Therapy in Peripheral Arterial Disease (EXITPAD) study, a multicenter randomized controlled trial including IC patients receiving SET or a walking advice. The SET program was supervised by physiotherapists and included interval-based treadmill walking approximating maximal pain combined with activities such as cycling and rowing. Patients usually started with three 30-minute sessions a week. Training frequency was adapted during the following year on the basis of individual needs. The primary outcome was gender differences regarding the change in absolute claudication distance (ACD) after SET. ACD was defined as the number of meters that a patient had covered just before he or she was forced to stop walking because of intolerable pain. Secondary outcomes were gender differences in change of functional walking distance, quality of life, and walking (dis)ability after SET. Walking distances were obtained by standardized treadmill testing according to the Gardner-Skinner protocol. Quality of life was measured by the 36-Item Short Form Health Survey, and walking (dis)ability was determined by the Walking Impairment Questionnaire (WIQ). Measurements were performed at baseline and after 3, 6, 9, and 12 months. Only patients who met the 12-month follow-up measure were included in the analysis. RESULTS A total of 113 men and 56 women were available for analysis. At baseline, groups were similar in terms of clinical characteristics and ACD walking distances (men, 250 meters; women, 270 meters; P = .45). ACD improved for both sexes. However, ACD increase was significantly lower for women than for men during the first 3 months of SET (Δ 280 meters for men vs Δ 220 meters for women; P = .04). Moreover, absolute walking distance was significantly shorter for women compared with men after 1 year (565 meters vs 660 meters; P = .032). Women also reported less on several WIQ subdomains, although total WIQ score was similar (0.69 for men vs 0.61 for women; P = .592). No differences in quality of life after SET were observed. CONCLUSIONS Women with IC benefit less during the first 3 months of SET and have lower absolute walking distances after 12 months of follow-up compared with men. More research is needed to determine whether gender-based IC treatment strategies are required.

[PMID: 26362632 PMCID: PMC4652630 DOI: 10.1161/circulationaha.114.013440] [Citation(s) in RCA: 40] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/02/2014] [Accepted: 09/08/2015] [Indexed: 11/16/2022]
Abstract
BACKGROUND Treatment for symptomatic peripheral artery disease includes lower extremity bypass surgery (LEB) and peripheral endovascular interventions (PVIs); however, limited comparative effectiveness data exist between the 2 therapies. We assessed the safety and effectiveness of LEB and PVI in patients with symptomatic claudication and critical limb ischemia. METHODS AND RESULTS In a community-based clinical registry at 2 large integrated healthcare delivery systems, we compared 883 patients undergoing PVI and 975 patients undergoing LEB between January 1, 2005 and December 31, 2011. Rates of target lesion revascularization were greater for PVI than for LEB in patients presenting with claudication (12.3±2.7% and 19.0±3.5% at 1 and 3 years versus 5.2±2.4% and 8.3±3.1%, log-rank P<0.001) and critical limb ischemia (19.1±4.8% and 31.6±6.3% at 1 and 3 years versus 10.8±2.5% and 16.0±3.2%, log-rank P<0.001). However, in comparison with PVI, LEB was associated with increased rates of complications up to 30 days following the procedure (37.1% versus 11.9%, P<0.001). There were no differences in amputation rates between the 2 groups. Findings remained consistent in sensitivity analyses by using propensity methods to account for treatment selection. CONCLUSIONS In patients with symptomatic peripheral artery disease, in comparison with LEB, PVI was associated with fewer 30-day procedural complications, higher revascularization rates at 1 and 3 years, and no difference in subsequent amputations.

Abstract
OBJECTIVE Of this study were to evaluate the functional independence of patients with intermittent claudication and to verify its association with sociodemographic and clinical variables, walking ability and physical activity level. METHOD This was a descriptive, exploratory, cross-sectional study with a quantitative approach. Fifty participants (66.4 years; 68% male) were recruited from Claudication Unit of a tertiary hospital. Functional Independence Measure were used to evaluate functional incapacity; the Baltimore Activity Scale, to estimate the physical activity level and the Walking Impairement Questionnaire, the walking ability. RESULTS Participants had complete functional independence (124.8 + 2.0), low levels of physical activity (4.2 + 2.0), and impairment of walking ability; the worst performance was found in walking velocity domain (21.2 + 16.4). The functional independence score was associated with physical activity (r=0,402) and walking ability scores (distance, r=0,485; speed, r=0,463; stairs, r=0,337). CONCLUSION In conclusion, the level of functionality is associated with functional capacity in these patients.

Short-Term, High-Dose Fish Oil Supplementation Increases the Production of Omega-3 Fatty Acid-Derived Mediators in Patients With Peripheral Artery Disease (the OMEGA-PAD I Trial). J Am Heart Assoc 2015; 4:e002034.

Abstract
BACKGROUND Patients with peripheral artery disease (PAD) experience significant morbidity and mortality. The OMEGA-PAD I Trial, a randomized, double-blinded, placebo-controlled trial, addressed the hypothesis that short-duration, high-dose n-3 polyunsaturated fatty acids (n-3 PUFA) oral supplementation improves endothelial function and inflammation in PAD. METHODS AND RESULTS Eighty patients with stable claudication received 4.4 g of fish oil or placebo for 1 month. The primary end point was endothelial function as measured by brachial artery flow-mediated vasodilation. Secondary end points included biomarkers of inflammation, n-3 polyunsaturated fatty acids metabolome changes, lipid profile, and walking impairment questionnaires. Although there was a significant increase in FMD in the fish oil group following treatment (0.7±1.8% increase from baseline, P=0.04), this response was not different then the placebo group (0.6±2.5% increase from baseline, P=0.18; between-group P=0.86) leading to a negative finding for the primary endpoint. There was, however, a significant reduction in triglycerides (fish oil: -34±46 mg/dL, P<0.001; placebo -10±43 mg/dL, P=0.20; between-group differential P-value: 0.02), and an increase in the omega-3 index of 4±1% (P<0.001) in the fish oil group (placebo 0.1±0.9%, P=0.49; between-group P<0.0001). We observed a significant increase in the production of pathway markers of specialized pro-resolving mediators generated from n-3 polyunsaturated fatty acids in the fish oil group. CONCLUSIONS High-dose, short-duration fish oil supplementation did not lead to a different response in the primary end point of endothelial function between the treatment and placebo group, but improved serum triglycerides and increased the production of downstream n-3 polyunsaturated fatty acids-derived products and mediators in patients with PAD.
