All guidelines worldwide strongly recommend exercise as a pillar of the management of patients affected by lower extremity peripheral artery disease (PAD). Exercise therapy in this setting presents different modalities, and a structured programme provides optimal results. This clinical consensus paper is intended for clinicians to promote and assist for the set-up of comprehensive exercise programmes to best advice in patients with symptomatic chronic PAD. Different exercise training protocols specific for patients with PAD are presented. Data on patient assessment and outcome measures are narratively described based on the current best evidence. The document ends by highlighting disparities in access to supervised exercise programmes across Europe and the series of gaps for evidence requiring further research.

RESUMO
OBJECTIVE: The VOYAGER-PAD trial demonstrated the interest in dual pathway inhibition (DPI) (low dose rivaroxaban plus aspirin) to reduce limb and cardiovascular events after revascularisation for peripheral artery disease (PAD), but its applicability in clinical practice has not yet been assessed. This study aimed to assess the number of patients revascularised in France for PAD and to estimate the proportion of those matching the VOYAGER-PAD trial selection criteria. A secondary objective was to examine the prognosis of revascularised patients in a real world setting. METHODS: This observational retrospective study was conducted on the national hospital discharge database and included all patients with PAD who underwent lower extremity revascularisation for PAD (without lower extremity revascularisation in the two years prior to inclusion) from 1 January 2016 to 31 December 2019. Available VOYAGER-PAD selection criteria were then applied to the study population. RESULTS: In total, 180 870 patients were included (mean age 72.0 ± 12.2 years, 30.9% female), with approximately 45 000 patients revascularised annually. Among them, 90 379 (50.0%) matched the VOYAGER-PAD trial criteria (VOYAGER-PAD eligible subgroup; mean age 69.8 ± 12.1 years, 29.5% female). In the study population and the VOYAGER-PAD eligible subgroup, 33.9% and 26.6% of patients had diabetes, 28.1% and 19.9% had chronic coronary artery disease, and 14.6% and 5.7% had renal failure, respectively. Overall, 73.1% of study patients were treated by an endovascular approach (75.5% in the VOYAGER-PAD eligible subgroup). In patients with more than one year of follow up, 45.4% of study patients and 36.0% of the VOYAGER-PAD eligible subgroup experienced a limb or cardiovascular event. The median time until the first event and in hospital death was 4.8 months and 7.8 months, respectively (6.7 months and 12.9 months in the VOYAGER-PAD eligible subgroup). CONCLUSION: The burden of PAD for revascularisation and secondary events is considerable. One half of revascularised patients in France are eligible for DPI therapy. Those patients are younger, with fewer comorbidities, and better outcomes.

Secondary lymphedema (LD) corresponds to a severe lymphatic dysfunction leading to the accumulation of fluid and fibrotic adipose tissue in a limb. Here, we identified apelin (APLN) as a powerful molecule for regenerating lymphatic function in LD. We identified the loss of APLN expression in the lymphedematous arm compared to the normal arm in patients. The role of APLN in LD was confirmed in APLN knockout mice, in which LD is increased and associated with fibrosis and dermal backflow. This was reversed by intradermal injection of APLN-lentivectors. Mechanistically, APLN stimulates lymphatic endothelial cell gene expression and induces the binding of E2F8 transcription factor to the promoter of CCBE1 that controls VEGF-C processing. In addition, APLN induces Akt and eNOS pathways to stimulate lymphatic collector pumping. Our results show that APLN represents a novel partner for VEGF-C to restore lymphatic function in both initial and collecting vessels. As LD appears after cancer treatment, we validated the APLN-VEGF-C combination using a novel class of nonintegrative RNA delivery LentiFlash® vector that will be evaluated for phase I/IIa clinical trial.

BACKGROUND: A French intersociety consensus on behalf the Société Française de Médecine Vasculaire and the Société de Chirurgie Vasculaire et Endovasculaire was proposed in 2021 for the management of patients with lower extremity peripheral artery disease (LEAD). Recent studies have been published and an update of this consensus about the management of low-density lipoprotein cholesterol (LDLc) and hypertriglyceridemia was required. METHODS: A steering committee of 12 vascular physicians and surgeons defined questions of interest about LDLc and hypertriglyceridemia management. A French expert panel voted the proposals. Consensus was considered to have been achieved if more than 80% of the responses corresponded to either "Agreement" or "Disagreement". RESULTS: Among the 56 experts who were asked to participate, 46 (82%) accepted. After the first round of the Delphi procedure, the 4 proposals reached consensus. The following suggestions and recommendations were approved: 1. For LEAD patients treated by the highest tolerated statin dose ± ezetimibe and who have an LDLc ≥0.70 g/L, we recommend adding a proprotein convertase subtilisin/kexin type 9 inhibitor. 2. For LEAD patients treated by statin and who have elevated triglyceride level between ≥150 mg/dL and ≤500 mg/dL, we suggest adding Icosapent Ethyl. 3. Before adding Icosapent Ethyl in LEAD patients treated with statin, we suggest looking for symptoms that may suggest atrial fibrillation. 4. For LEAD patients treated by Icosapent Ethyl and who have symptoms that suggest atrial fibrillation, we recommend performing an electrocardiogram. CONCLUSIONS: This update will help clinicians to improve LEAD patient management.

BACKGROUND: There is scarce evidence on the effectiveness and safety of recommended-dose direct acting oral anticoagulants (DOACs) in obese patients with venous thromboembolism (VTE). MATERIAL AND METHODS: We used the data in the RIETE registry to compare the rates of VTE recurrences and major bleeding during long-term therapy with DOACs at recommended doses in patients with body mass index ≥30 kg/m2 (obese) vs. those with BMI 18.5-24.9 kg/m2 (normal weight). We performed regression models with competing risks for death. RESULTS: From January 2013 through October 2022, 2885 obese patients and 2676 with normal weight in RIETE received rivaroxaban (n = 3020), apixaban (n = 1754), edoxaban (n = 636) or dabigatran (n = 151). Median age was 63 years and 52 % were female. At baseline, obese patients were more likely to have diabetes (18.6 % vs. 8.4 %), hypertension (51.9 % vs. 31.4 %) or pulmonary embolism (67.7 % vs. 61 %), and less likely to have renal insufficiency (5.3 % vs. 16 %) or anaemia (21.8 % vs. 28 %%). During anticoagulation (median, 147 vs. 101 days), the obese had a similar rate of VTE recurrences (1.71 vs. 2.14 events per 100 patients-years; hazard ratio (HR): 0.81; 95 % CI: 0.49-1.34) or major bleeding (1.45 vs. 1.76 per 100 patients-years; HR: 0.91; 95 % CI: 0.52-1.59) than those with normal weight. These findings persisted after multivariable analysis (recurrent VTE, HR: 0.80; 95 % CI: 0.48-1.32; major bleeding, HR: 1.11; 95 % CI: 0.60-2.07). CONCLUSION: The use of DOACs at recommended doses in obese patients with VTE was associated with similar rates of VTE recurrences or major bleeding than in patients with normal weight.

AIM: The present study investigated the risk of bleeding when antidepressants are added to antithrombotics. METHODS: Using data registered in VigiBase®, the WHO pharmacovigilance database, between 01/01/2000 and 31/12/2022, we compared the risk of reporting "serious" bleeding (Reporting Odds Ratio, ROR) with antidepressants + antithrombotics versus antithrombotics alone. RESULTS: Increased values of ROR were found for the association Serotonin Reuptake Inhibitors (SRIs) + Direct Oral Anticoagulants (DOACs) versus DOACs alone (ROR=1.49(1.17-1.89)). Similar results were found for Factor Xa inhibitors or Thrombin inhibitors. This association was also found for other antithrombotics: Vitamin K Antagonists (ROR=1.37(1.12-1.68)), Platelet Aggregation Inhibitors PAIs (ROR=1.38(1.21-1.57)) and Heparins (2.04(1.59-2.62)) but not with other antidepressants (Non-Selective Monoamine Reuptake Inhibitors, NSMRIs). CONCLUSION: The present study suggests an increased risk of "serious" bleeding when SRIs (but not NSMRIs) are associated with antithrombotics (all antithrombotics and not only DOACs).

Background: Complications under anticoagulant treatment in patients with COVID-19-associated venous thromboembolism (VTE) have not been consistently reported. Objectives: This study aimed to compare the 90-day rates of VTE recurrences and major bleeding in patients with COVID-19-associated VTE versus those with VTE without COVID-19. Methods: We used the RIETE registry to compare the 3-month outcomes in patients with COVID-19-associated VTE versus those with VTE without COVID-19. Results: The study included 1,747 patients with COVID-19-associated VTE and 8,711 with VTE without COVID-19. Patients with COVID-19-associated VTE were more likely to be hospitalized at baseline and to present with pulmonary embolism. During the first 90 days, 123 patients (1.17%) developed VTE recurrences, and 266 (2.54%) experienced major bleeding. Patients with COVID-19-associated VTE had a similar rate of VTE recurrences (0.9% vs 1.2%) but a higher rate of major bleeding (4.6% vs 2.1%; P < .001) than those without COVID-19. Multivariable analysis adjusted for competing risks showed that patients with COVID-19-associated VTE had an increased risk of major bleeding (subhazard ratio, 1.395; 95% confidence interval, 1.037-1.877). The 30-day mortality after major bleeding was 26.3% in patients with COVID-19-associated VTE and 17.7% in those without COVID-19. Conclusion: Patients with COVID-19-associated VTE had a 5-fold higher rate of major bleeding than VTE recurrences during the first 90 days of anticoagulation. In VTE patients without COVID-19, both rates were similar. These findings highlight the importance of carefully monitoring and optimizing anticoagulation in these patients.
RESUMO
BACKGROUND: Data on recurrence after the end of anticoagulation for a first event of cancer-associated venous thromboembolism (VTE) are scarce. OBJECTIVES: Our aim was to assess predictors of VTE recurrence during a 1-year follow-up period. METHODS: This study is an analysis of RIETE, an international, multicenter, prospective cohort study of patients diagnosed with VTE. Patients had to have active cancer at the time of VTE and to have withdrawn from anticoagulation after 3 months of full treatment. Analyses were performed using Fine and Gray models, with death as a competing risk, and multiple imputation of missing data was performed by chained equations. RESULTS: Among 14 318 patients with cancer-associated VTE, 3414 had undergone time-limited anticoagulation for at least 3 months. The cumulative incidence function for recurrent VTE was 10.2% (95% CI, 9.1-11.5) at 1 year. Chronic kidney disease (a subhazard ratio [sHR] of 1.08 for 10-mL/min decrease in glomerular filtration rate; 95% CI, 1.02-1.14); cancer of the lung, brain, stomach, esophagus, liver, or ovary (sHR, 3.56; 95% CI, 1.07-11.80; compared with cancer of the oropharynx, larynx, or melanoma); cancer of the pancreas, the biliary tract, or of unknown origin (sHR, 6.86; 95% CI, 1.89-24.85); inferior vena cava filter (sHR, 3.16; 95% CI, 1.75-5.71); postthrombotic syndrome (sHR, 2.09; 95% CI, 1.06-4.15); and residual pulmonary thrombotic obstruction (sHR, 2.58; 95% CI, 1.38-4.82) were predictive of recurrence. Surgery during the 2 months before VTE was predictive of absence of recurrence (sHR, 0.60; 95% CI, 0.40-0.92). CONCLUSION: One year after anticoagulant cessation for cancer-associated VTE, approximately 10% of patients experienced recurrence. Discontinuing anticoagulant therapy seems safe, mainly in surgery-associated VTE.

AIMS: Clinical trials have found differences in bleeding locations between direct oral anticoagulants (DOAC) and vitamin K antagonists (VKA). The present study was performed to investigate these differences in real life using reports of adverse drug reactions registered in the World Health Organization's pharmacovigilance database, VigiBase®. METHODS: All bleeding registered between 1 January 2008 and 31 December 2021 in adults were included. The main objective was to compare bleeding locations reported with DOAC with those with VKA. As a secondary objective, we performed the same comparison with Xa vs. thrombin inhibitors. Results were presented as reporting odds ratios (RORs) adjusted on age, gender, origin of reports and co-medications with their 95% confidence interval. RESULTS: During this 14-year period, 142 228 instances of bleeding were registered with oral anticoagulants, including 39 570 with VKA and 102 658 with DOAC. Mean time to event was lower with DOAC (7.6 months) than with VKA (29.9 months) (P < .001). Significant differences in bleeding locations were found in the reports with less cerebral, urologic and nasal bleeding, more gynaecologic bleeding with DOAC than with VKA, without any significant differences in digestive and cutaneous locations. A higher risk of bleeding reports was found with Xa inhibitors vs. dabigatran whatever the locations (except digestive bleeding). CONCLUSION: This real-life study shows that the differences in bleeding locations between DOAC and VKA are not limited to the brain or gastrointestinal tracts. Significant differences were also found between Xa and thrombin inhibitors.

BACKGROUND: The optimal strength of compression needed to prevent post-thrombotic syndrome (PTS) after a proximal deep vein thrombosis (DVT) is debated. We aimed to assess whether 25 mm Hg elastic compression stockings (ECS) are non-inferior to 35 mm Hg ECS in preventing PTS after a DVT. METHODS: In this multicentre, double-blind, non-inferiority, randomised controlled trial, we enrolled adults (≥18 years) with a first ipsilateral proximal DVT attending 46 French vascular medicine hospital departments or private practices. Participants were randomly allocated (1:1, stratified by centre, age, and sex; with varying block sizes of two and four) to wear 25 mm Hg or 35 mm Hg ECS for 2 years. The primary outcome was the cumulative rate of PTS 2 years after inclusion, defined by a Villalta scale (≥5). Efficacy was assessed by intention-to-treat and in eligible participants who had complete primary outcome data. A per-protocol analysis was also conducted among compliant patients as a secondary outcome measure. Safety was assessed in all participants who used ECS at least once, and for which we have at least some tolerance information during follow-up. The margin for non-inferiority was 12·5%. This study is registered with ClinicalTrials.gov, NCT01578122, and has been completed. FINDINGS: Between June 28, 2012, and July 21, 2017, we enrolled 341 eligible participants who consented to randomisation. 233 (68%) were men and median age was 59 years (IQR 45-70). Collection of ethnicity and race as a routine research variable is not authorised in France. Median follow-up was 735 days (IQR 721-760). 249 (73%) had complete data at 2 years. For the primary analysis, 40 (31%) of 129 participants with complete data in the 25 mm Hg ECS group and 40 (33%) of 120 in the 35 mm Hg group had PTS (absolute difference -2·3% [90% CI -12·1 to 7·4], pnon-inferiority=0·0062; relative risk 0·93, 95% CI 0·65 to 1·33). Results remained similar after imputation of missing data in patients we were authorised to do so: the cumulative proportion of PTS was 45 (29%) of 154 in the 25 mm Hg ECS group versus 52 (35%) of 148 in the 35 mm Hg ECS group (relative risk 0·83, 95% CI 0·60 to 1·16). Absolute difference was -5·9%, (90% CI -14·7 to 2·9), p=0·0003 for non-inferiority. Adherence was optimal (>80% and modified GIRERD score of 0-2) for 75 (51%) of 146 patients assigned to 25 mm Hg ECS and for 56 (42%) of 134 patients assigned to 35 mm Hg ECS (p=0·11). Regarding major adverse events related to ECS, there were no between-group differences in rates of deep vein thrombosis (0 vs 1 [0·6%]), ipsilateral leg ulcer (0 vs 1 [0·6%]), infection (0 vs 0), or death (0 vs 0) between the 169 patients evaluated in the 25 mm Hg ECS group and the 159 patients in the 35 mm Hg ECS group. Two (1%) of 328 patients who ever wore ESC developed ECS-related serious adverse events, one distal DVT and one leg ulcer (both in the 35 mm Hg ECS group). In the 25 mm Hg group, 6 patients died, 14 had a venous thromboembolic recurrence (proximal DVT or pulmonary embolism), and 7 had a major bleed. In the 35 mm Hg group, 5 patients died, 10 had a venous thromboembolic recurrence (proximal DVT or pulmonary embolism), and 6 had a major bleed. INTERPRETATION: Although we did not reach the prespecified sample size, our results suggest that 25 mm Hg ECS are non-inferior to 35 mm Hg ECS in preventing PTS. Larger more powerful studies are needed. FUNDING: Laboratoires Innothera, France.

Background: Current guidelines recommend the use of direct oral anticoagulants (DOACs) for patients with venous thromboembolism (VTE). However little is known about the use of DOACs in daily practice. Methods: We used the RIETE registry to identify predictors of use of DOACs for initial and/or long-term therapy of VTE based on patient-related factors, institution-related factors or over time. Results: Among 41,678 patients from March 2013 to September 2021, 12,286 (29%) used DOACs: for initial therapy 6,456; for long-term therapy 12,046. On multivariable analysis, independent predictors were: age < 65 years (odds ratio [OR]: 1.30; 95% CI: 1.23-1.38), body weight <50 kg (OR: 0.54; 95% CI: 0.45-0.65) or >120 kg (OR: 0.64; 95% CI: 0.53-0.77), initial VTE presentation as pulmonary embolism (OR: 1.18; 95% CI: 1.13-1.25), recent bleeding (OR: 0.53; 95% CI: 0.45-0.63), renal insufficiency (OR: 0.44; 95% CI: 0.38-0.51), liver cirrhosis (OR: 0.32; 95% CI: 0.20-0.52), thrombocytopenia (OR: 0.40; 95% CI: 0.34-0.49), atrial fibrillation (OR: 1.58; 95% CI: 1.42-1.75) and prior VTE (OR: 1.14; 95% CI: 1.06-1.22). The DOACs were more likely used in other European countries (OR: 8.97; 95% CI: 8.49-9.49), America (OR: 6.35; 95% CI: 5.67-7.11) or in other countries of the world (OR: 2.99; 95% CI: 2.70-3.31) than in Spain, and progressively increased from 2013-2015 to 2016-2018 (OR: 2.78; 95% CI: 2.62-2.95) and 2019-2021 (OR: 6.36; 95% CI: 5.95-6.80). Conclusion: In this large multinational VTE registry, variations were observed in the use of DOACs according to patient or country factors, and over time. The safety, costs, and influence of the DOACs on VTE-related outcomes in daily practice warrant further investigation.
RESUMO
This paper describes a currently on-going multicenter, randomized controlled trial designed to assess the efficacy of calf neuromuscular electrical stimulation (NMES) on changes in maximal walking distance in people with lower extremity peripheral artery disease (PAD), compared with a non-intervention control-group. This study (NCT03795103) encompasses five participating centers in France. PAD participants with a predominant claudication at the calf level and a maximal treadmill walking distance ≤300 m are randomized into one of the two groups: NMES group or Control group. The NMES program consists of a 12-week program of electrical stimulations at the calf-muscle level. The primary outcome of the study is the change in maximal treadmill walking distance at 12 weeks. Main secondary outcomes include changes in the pain-free treadmill walking distance; 6 min total walking distance; global positioning system (GPS)-measured outdoor walking capacity; daily physical activity level by accelerometry; self-reported walking impairment; self-reported quality of life; ankle-brachial index; and skin microvascular function, both at the forearm and calf levels. Recruitment started in September 2019 and data collection is expected to end in November 2022.
RESUMO
The optimal first line management of patients with symptomatic chronic lower extremity peripheral artery disease (PAD) includes secondary prevention of cardiovascular risk factors, pharmacological treatment, and supervised exercise therapy (SET). SET programs have shown to be effective in improving walking performance, functional performance, and quality of life. However, despite a large body of evidence, and despite national and international guidelines recommending SET as first line therapy, SET remains largely underused in patients with chronic PAD. This position paper aims to describe how SET is perceived, its accessibility and structure through Europe. An anonymous web-based survey was used. It comprised 21 questions developed in conjunction with an angiologist and a clinical exercise physiologist specialist in vascular rehabilitation. We had 131 responders from 17 countries. For patients with PAD, SET programs exist only in 59% of European countries. SET reimbursement is available in 41% of countries. SET programs showed to be heterogeneous across countries. Thirty-four percent of the SET programs are PAD-dedicated, while 23% are part of a cardiac rehabilitation program. In addition, among existing SET programs, 65% are dedicated to symptomatic patients with PAD only, 9% to both asymptomatic and symptomatic, 8% to post-revascularized patients only, and 1% to asymptomatic patients with PAD only. Finally, 17% reported not knowing which patients are eligible for enrolment in a SET program. Duration, frequency, and modality of SET also varied from country to country. Overall, these data indicate that a large variability of SET availability and characteristics exists across Europe. Therefore, there is an urgent need to provide detailed guidance to deliver optimal exercise therapeutic care in patients with PAD.

Importance: Prior studies have observed an association between the burden of atherosclerotic vascular disease and the risk of venous thromboembolism (VTE). The association is not well described in peripheral artery disease (PAD) after lower extremity revascularization (LER). Objective: To describe the risk of, factors associated with, and outcomes after VTE, as well as the association of low-dose rivaroxaban plus antiplatelet therapy with VTE after LER. Design, Setting, and Participants: This global, multicenter cohort study used data from the Vascular Outcomes Study of ASA (acetylsalicylic acid) Along With Rivaroxaban in Endovascular or Surgical Limb Revascularization for PAD (VOYAGER PAD) randomized clinical trial, which enrolled patients from 2015 to 2018 with median follow-up of 28 months. Participants included patients with PAD undergoing LER. Patients with an indication for therapeutic anticoagulation were excluded. Data were analyzed from September 2020 to September 2021. Exposure: Randomization to rivaroxaban 2.5 mg twice daily or placebo on a background of aspirin 100 mg daily; short-term clopidogrel was used at the discretion of the treating physician. Main Outcomes and Measures: Symptomatic VTE was a prespecified secondary outcome and prospectively collected. Results: Among 6564 patients (median [IQR] age, 67 [61-73] years; 4860 [74.0%] men), 66 patients had at least 1 VTE. The 3-year rate of VTE in patients receiving placebo was 1.7%, and the pattern of risk was linear (year 1: 0.5%; year 2: 1.1%). After multivariable modeling, weight (hazard ratio [HR], 3.04; 95% CI, 1.09-8.43), hypertension (HR, 2.11; 95% CI, 0.91-4.89), prior amputation (HR, 2.07; 95% CI, 0.95-4.53), and older age (HR, 1.81; 95% CI, 1.06-3.11) were associated with increased risk of VTE. VTE was associated with risk of subsequent mortality (HR, 7.22; 95% CI, 4.66-11.19). Compared with aspirin alone, rivaroxaban plus aspirin was associated with lower VTE risk (HR, 0.61; 95% CI, 0.37-0.998; P = .047), with benefit apparent early and sustained over time. This association was not modified by use of clopidogrel at randomization (without clopidogrel: HR, 0.55; 95% CI, 0.29-1.07; with clopidogrel: HR, 0.69; 95% CI, 0.32-1.48; P for interaction = .67). Conclusions and Relevance: In this cohort study, there was continuous risk for VTE after LER in patients with PAD, with greater risk in patients who were older and had obesity and those with more severe PAD, as reflected by prior amputation. Low-dose rivaroxaban plus aspirin was associated with lower VTE risk compared with aspirin alone, with benefits apparent early and continued over time. The spectrum of venous and arterial thrombotic events and overall benefits of more potent antithrombotic strategies for prevention should be considered after LER for PAD.
