[PMID: 39433055 DOI: 10.1016/s2352-3026(24)00281-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2024] [Revised: 08/27/2024] [Accepted: 08/30/2024] [Indexed: 10/23/2024]
Abstract
Over the last decade, the advent of direct oral anticoagulants (DOACs) has rapidly changed the landscape of anticoagulation. In the early 2010s, DOACs became widely available for stroke prevention in atrial fibrillation and the treatment of venous thromboembolism. About 10 years later, approximately two-thirds of patients requiring oral anticoagulant treatment were receiving a DOAC. The results of several post-marketing studies consistently confirmed the findings of phase 3 clinical trials, and research has focused on new areas of development, with heterogeneous results. A role for DOACs has emerged for patients with peripheral artery disease and other challenging conditions, such as cancer-associated thrombosis, unusual-site venous thromboembolism, and end-stage renal disease. Conversely, clinical trials showed that DOACs were not efficacious in patients with valvular atrial fibrillation, mechanical heart valves, embolic strokes of undetermined source, or antiphospholipid syndrome. In this Review, we discuss the impact of DOACs in clinical practice over the last decade, new areas under development, and practical issues in the management of these drugs.

Abstract
Patients with peripheral artery disease (PAD) who undergo lower extremity revascularization (LER) are at high risk for cardiovascular and limb-related ischemic events. The role of antithrombotic therapy is to prevent thrombotic complications, but this requires balancing increased risk of bleeding events. The dual pathway inhibition (DPI) strategy including aspirin and low-dose rivaroxaban after LER has been shown to reduce major adverse cardiovascular and limb-related events without significant differences in major bleeding. There is now a need to implement the broad adoption of DPI therapy in PAD patients who have undergone LER in routine practice.

Abstract
Patients with peripheral artery disease (PAD) experience major cardiovascular and limb events. Antithrombotic strategies including antiplatelets and anticoagulants remain a cornerstone of treatment and prevention. Recent trials have shown heterogeneity in the response to antithrombotic therapies in patients presenting primarily with PAD when compared to those presenting primarily with coronary artery disease. In addition, there is observed heterogeneity with regards to the effects of antiplatelets and anticoagulants with respect to different outcomes including cardiovascular and major adverse limb events. This, coupled with risks of bleeding, requires a patient-centered and holistic assessment of benefit-risk when selecting antithrombotic strategies for patients with PAD. A global multidisciplinary work group was convened to evaluate antithrombotic strategies in PAD and to summarize the current state of the art. Common clinical scenarios around antithrombotic decision making were provided. Finally, insights with regard to implementation future investigation were described.

Abstract
Our study aimed to assess the influence of incorporating new oral anticoagulant (NOAC) therapy on clinical outcomes among patients who underwent endovascular intervention for below-the-knee (BTK) occlusions necessitating reintervention. The inclusion criteria encompassed patients with chronic limb-threatening ischemia (CLTI) and had undergone a successful endovascular intervention for BTK artery occlusion, necessitating reintervention. Patients who underwent endovascular interventions for BTK reocclusion were compared to those who received dual-pathway inhibition with NOAC (rivaroxaban 2.5 mg 2 × 1) and clopidogrel (NOAC group), or dual-antiplatelet therapy with clopidogrel and aspirin (DAPT group). The primary endpoints were target vessel reocclusion and target lesion revascularization (TLR) at the 1-year follow-up, while major and minor amputations served as the secondary endpoint. Additionally, a one-year comparison was conducted between the two groups for major bleeding events. 64 patients in our clinic treated with endovascular reintervention (NOAC = 28, DAPT = 34). The TLR rate is 10.7% in NOAC group (N = 3) and 32.4% in DAPT group (N = 11, p = 0.043). The target vessel reocclusion rate is 17.8% in NOAC group (N = 5) and 41.2% in DAPT group (N = 14, p = 0.048). Minor or major amputation rate at 1-year follow-up was 3.6% in NOAC group (N = 1) and 11.7% in DAPT group (N = 4, p = 0.245). The patency rate is significantly higher, and the TLR rate is significantly lower in the NOAC group compared to the DAPT group, with no significant difference in major bleeding between the two groups. Although no statistically significant difference exists in amputation rates, a numerical distinction is evident.

Abstract
ABSTRACT Peripheral arterial disease (PAD) is the third leading cause of atherosclerotic morbidity after coronary heart disease and stroke yet is widely underdiagnosed and undertreated. Treatment of risk factors such as diabetes and cigarette smoking can benefit patients with PAD. Patients should have adequate blood pressure and lipid control to decrease clinical manifestations and symptoms of PAD. Use of antithrombotic medications should be individualized to the patient depending on the presence of symptoms, revascularization, and comorbidities. All patient care providers, including physicians, pharmacists, nurse practitioners, and physician assistants, should incorporate PAD screening in their at-risk patients to improve access for appropriate earlier diagnosis, initiation of guideline directed therapy, and risk factor modification to reduce both major adverse CV and limb outcomes. The purpose of this narrative review is to provide an overview of PAD and summarize clinical trial evidence and guideline recommendations for screening and treatment to increase awareness among health care providers to ultimately have a positive impact on patient care.

J Vasc Surg 2024; 79:1466-1472.e1. [PMID: 38278371 PMCID: PMC11111331 DOI: 10.1016/j.jvs.2024.01.196] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2023] [Revised: 01/17/2024] [Accepted: 01/19/2024] [Indexed: 01/28/2024]
Abstract
OBJECTIVE The role of direct oral anticoagulants (DOACs) in chronic limb-threatening ischemia after revascularization is unknown. Current evidence-based guidelines do not provide clear guidance on the role of anticoagulation or the selection of anticoagulant. Current practice is highly varied and based on provider and patient preference. The purpose of this study was to measure the impact of different anticoagulants on the incidence of major adverse limb events (MALEs) after revascularization for chronic limb-threatening ischemia, major adverse cardiovascular events (MACEs), all-cause mortality, and hospitalization for major bleeding events. METHODS This was a single-center, observational, retrospective cohort study. Subjects were eligible if they were 18 years or older; underwent endovascular or open revascularization for chronic limb-threatening ischemia, rest pain, or tissue loss; and were subsequently prescribed apixaban, rivaroxaban, or warfarin. The primary end point was the incidence of MALEs, including above-ankle amputation or major index-limb reintervention, within 1 year of index event. Secondary end points included the rate of all-cause mortality, MACEs, and incidence of International Society on Thrombosis and Haemostasis (ISTH) major bleeding. RESULTS From January 1, 2017, to September 20, 2022, 141 patients met the inclusion and exclusion criteria and were reviewed. The median age was 67 years, with 92 patients prescribed apixaban or rivaroxaban and 49 patients prescribed warfarin. Of these, 42 patients were prescribed triple antithrombotic therapy, 88 dual antithrombotic therapy, and 13 anticoagulant monotherapy. The primary outcome of 1-year MALEs occurred in 36.7% of the warfarin group and 33.7% of the DOAC group (relative risk [RR], 1.09; 95% CI, 0.53-2.25; P = .72). Secondary outcomes of 1-year MACEs (10.2% vs 4.3%; RR, 2.35; 95% CI, 0.60-9.18; P = .18) and 1-year all-cause mortality (26.5% vs 16.3%; RR, 1.63; 95% CI, 0.70-3.78; P = .15) did not differ between the groups. The secondary safety outcome of 1-year ISTH major bleeding occurred in 16.3% of the warfarin group and 4.3% of the DOAC group (RR, 3.76; 95% CI, 1.07-13.19; P = .015). CONCLUSIONS In patients with chronic limb-threatening ischemia who were revascularized and prescribed anticoagulation with apixaban, rivaroxaban, or warfarin on discharge, no difference in MALEs, MACEs, or all-cause mortality was found. However, 1-year admissions for ISTH major bleeding were significantly higher among patients prescribed warfarin. A randomized trial may confirm these findings.

Abstract
PURPOSE OF REVIEW Patients with lower extremity peripheral artery disease (PAD) are at high risk for major adverse cardiovascular events (MACE) and major adverse limb events (MALE). This manuscript will review the current evidence for medical therapy in patients with PAD according to different clinical features and the overall cardiovascular (CV) risk. RECENT FINDINGS The management of PAD encompasses non-pharmacologic strategies, including lifestyle modification such as smoking cessation, supervised exercise, Mediterranean diet and weight loss as well as pharmacologic interventions, particularly for high risk patients. Benefits for reduction of CV and limb outcomes have been demonstrated for new therapies, including antithrombotic therapy (i.e., low-dose rivaroxaban plus aspirin), lipid lowering therapy (i.e., proprotein convertase subtilisin/kexin type 9 inhibitors), and glucose lowering therapy (i.e., sodium-glucose cotransporter-2 inhibitors and glucagon-like peptide-1 receptor agonists). However, the adoption of these therapies in PAD remains suboptimal in practice. Implementation science studies have recently shown promising results in PAD patients. Comprehensive medical and non-medical management of PAD patients is crucial to improving patient outcomes, mitigating symptoms, and reducing the risk of MACE and MALE. A personalized approach, considering the patient's overall risk profile and preference, is essential for optimizing medical management of PAD.

Abstract
OBJECTIVE Antiplatelet agents are commonly used after peripheral endovascular intervention (PVI). However, the effect of full-dose anticoagulation on outcomes after PVI is not well-established. We sought to investigate whether full-dose anticoagulation after PVI is associated with adverse events. METHODS We utilized the Vascular Quality Initiative to study patients undergoing index PVI for claudication (2010-2019), stratified by the presence or absence of an anticoagulant on discharge. The primary outcomes were 2-year patency, major adverse limb events (MALE), and mortality. We built a propensity score adjusting for comorbidities and employed inverse probability weighting to estimate the association of anticoagulation with outcomes. RESULTS We identified 26,240 patients; 9.1% were discharged on an anticoagulant. Patients receiving any anticoagulation had a significantly higher risk of mortality (adjusted hazard ratio [aHR], 1.61; 95% confidence interval [CI], 1.35-1.92), but not MALE, or patency loss. Patients receiving a vitamin K antagonist had a significantly higher risk of patency loss (aHR, 1.32; 95% CI, 1.09-1.60), MALE (aHR, 1.33; 95% CI, 1.13-1.57), and mortality (aHR, 1.46; 95% CI, 1.27-1.69). Patients on an oral Factor Xa inhibitors had a significantly lower risk of patency loss (aHR, 0.61; 95% CI, 0.41-0.93) but increased mortality (aHR, 1.51; 95% CI, 1.19-1.92). CONCLUSIONS Therapeutic anticoagulation after PVI is associated with higher risk of all-cause mortality. Although oral Factor Xa inhibitors are associated with decreased risk of patency loss, vitamin K antagonists are associated with higher risk of patency loss, MALE, and death. Further prospective studies are necessary to study the safety and efficacy of full-dose anticoagulation after PVI.

Rivaroxaban plus aspirin vs. dual antiplatelet therapy in endovascular treatment in peripheral artery disease and analysis of medication utilization of different lesioned vascular regions. Front Surg 2023; 10:1285553.

Abstract
Background In the management of Peripheral Arterial Disease (PAD), the administration of anticoagulant or antiplatelet agents is imperative. The use of Dual Antiplatelet Therapy (DAPT) in conjunction with rivaroxaban has shown potential in mitigating adverse outcomes. Given the heterogeneity in the pathology of lower limb arteries, there is a compelling case for individualized treatment strategies. Methods In a single-center retrospective study on pharmacotherapy for peripheral artery disease, patients were treated with either aspirin combined with rivaroxaban or aspirin coupled with clopidogrel. The primary efficacy outcome encompassed a composite of increases in the Rutherford classification, acute limb ischemia, amputations due to vascular causes, target lesion revascularization, myocardial infarction, ischemic stroke, and cardiovascular death. The primary safety outcome was major bleeding, as defined by the Thrombolysis in Myocardial Infarction (TIMI) criteria; meanwhile, major bleeding as categorized by the International Society on Thrombosis and Haemostasis (ISTH) served as a secondary safety outcome. The study differentiated between two subgroups: patients with only above-the-knee and below-the-knee arterial lesions. Results From January 2016 to December 2021, 455 patients received either clopidogrel plus aspirin or rivaroxaban plus aspirin following endovascular treatment (EVT). The rivaroxaban group (n = 220) exhibited a lower incidence of primary efficacy outcomes [49.1% vs. 60.4%, hazard ratio (HR) 0.77, P = 0.006] but had more TIMI major bleeding events (5.9% vs. 2.1%, HR 2.6, P = 0.04). ISTH major bleeding events did not show a significant difference, though a higher percentage of rivaroxaban patients discontinued medication due to bleeding (10% vs. 4.7%, HR 2.2, P = 0.03). In the above-the-knee arterial disease subgroup, the rivaroxaban group demonstrated a lower incidence of primary efficacy outcomes (28.2% vs. 45.2%, HR 0.55, P = 0.02). In the below-the-knee arterial disease subgroup, no significant difference was observed in the occurrence of primary efficacy events between the two groups (58.7% vs. 64.8%, HR 0.76, P = 0.14). Conclusion Rivaroxaban plus aspirin improved outcomes compared to DAPT in patients with lower extremity artery disease. Similar findings were observed in the above-the-knee artery lesion-only group. However, in the below-the-knee artery lesion-only group, rivaroxaban plus aspirin did not surpass DAPT in efficacy. Regarding safety, rivaroxaban plus aspirin exhibited higher bleeding risks and more frequent treatment discontinuation than aspirin combined with clopidogrel.

Abstract
BACKGROUND The role of thrombin in vascular pathology is a focus of investigation. The incorporation of direct Factor Xa inhibition into practice patterns is based on its theoretical dual-pathway attenuation of both thrombin generation and platelet aggregation. However, quantification of the effect of direct anti-Xa medications on platelet function is not established. Thromboelastography with platelet mapping (TEG-PM) leverages dual-pathway metrics to provide comprehensive coagulation profiles. We evaluated the effects of direct oral anticoagulants (DOACs) on coagulation and platelet function profiles and correlate these data with postoperative major adverse limb events (MALEs) in patients with PAD. METHODS We conducted a prospective study of patients undergoing lower extremity revascularization with serial perioperative TEG-PM analysis. Patients on DOACs were compared to those not on DOACs, and stratified by concurrent mono-antiplatelet or dual-antiplatelet regimens (MAPT/DAPT). Postoperative MALE was recorded and difference in antithrombotic regimens and TEG-PM analysis compared between groups. RESULTS Four hundred seventy-one samples from 141 patients were analyzed. Twenty-nine point five percent were reflective of circulating DOAC therapy. Compared to MAPT alone, patients on DOAC + MAPT exhibited longer time to clot formation (R-time) [7.4 (±2.4) vs. 6.7 (±2.7); P < 0.02], but less platelet inhibition. Patients on DAPT exhibited greater platelet inhibition compared to either group [23.7 (±26.9) vs. 31.0 (±28.3) vs. 42.2 (±31.2); P < 0.01]. Patients who experienced MALE were more likely to be on DOAC therapy [43.8% vs. 22.0% P = 0.02]. Thromboelastography with platelet mapping analysis from patients who experienced MALE also demonstrated longer R-time [8.6 (±3.9 vs. 7.3 (±3.0); P = 0.05] and increased maximum clot amplitude (MA) [66.7 (±4.2) vs. 61.8 (±8.2); P = 0.001]. CONCLUSIONS Direct oral anticoagulant therapy resulted in a prolonged R-time but had no impact on platelet inhibition. Patients who experienced MALE were more often on DOACs and demonstrated an increased R-time, but also showed greater platelet reactivity evident by increased MA, suggesting DOACs may not be effective at protecting against MALE. Further research comparing DOAC therapy to a DAPT approach may add clarity to emerging multimodal antithrombotic recommendations.

Abstract
Peripheral artery disease (PAD) is a major health problem with increased cardiovascular mortality, morbidity and disabling critical limb threatening ischemia (CLTI) and amputation. Diabetes mellitus (DM) and cigarette smoke are the main risk factors for the development of PAD. Although diabetes related PAD shows an accelerated course with worse outcome regarding complications, mortality and amputations compared with non-diabetic patients, current medical treatment does not make this distinction and includes standard antiplatelet and lipid lowering drugs for all patients with PAD. In this review we discuss the pathophysiologic mechanisms of PAD, with focus on differences in thrombo-inflammatory processes between diabetes-related and smoking-related PAD, and hypothesize on possible mechanisms for the progressive course of PAD in DM. Furthermore, we comment on current medical treatment and speculate on alternative medical drug options for patients with PAD and DM.

Abstract
Despite evidence-based therapies, patients presenting with atherosclerosis involving more than one vascular bed, such as those with peripheral artery disease (PAD) and concomitant coronary artery disease (CAD), constitute a particularly vulnerable group characterized by enhanced residual long-term risk for major adverse cardiac events (MACE), as well as major adverse limb events (MALE). The latter are progressively emerging as a difficult outcome to target, being correlated with increased mortality. Antithrombotic therapy is the mainstay of secondary prevention in both patients with PAD or CAD; however, the optimal intensity of such therapy is still a topic of debate, particularly in the post-acute and long-term setting. Recent well-powered randomized clinical trials (RCTs) have provided data in favor of a more intense antithrombotic therapy, such as prolonged dual antiplatelet therapy (DAPT) with aspirin and a P2Y12 inhibitor or a therapy with aspirin combined with an anticoagulant drug. Both approaches increase bleeding and selection of patients is a key issue. The aim of this review is, therefore, to discuss and summarize the most up-to-date available evidence for different strategies of anti-thrombotic therapies in patients with chronic PAD and CAD, particularly focusing on studies enrolling patients with both types of atherosclerotic disease and comparing a higher- versus a lower-intensity antithrombotic strategy. The final objective is to identify the optimal tailored approach in this setting, to achieve the greatest cardiovascular benefit and improve precision medicine.

Abstract
Patients with peripheral artery disease (PAD) are at an increased risk of major adverse cardiovascular events, and those with disease in the lower extremities are at risk of major adverse limb events primarily driven by atherothrombosis. Traditionally, PAD refers to diseases of the arteries outside of the coronary circulation, including carotid, visceral and lower extremity peripheral artery disease, and the heterogeneity of PAD patients is represented by different atherothrombotic pathophysiology, clinical features and related antithrombotic strategies. The risk in this diverse population includes systemic risk of cardiovascular events as well as risk related to the diseased territory (e.g., artery to artery embolic stroke for patients with carotid disease, lower extremity artery to artery embolism and atherothrombosis in patients with lower extremity disease). Moreover, until the last decade, clinical data on antithrombotic management of PAD patients have been drawn from subanalyses of randomized clinical trials addressing patients affected by coronary artery disease. The high prevalence and related poor prognosis in PAD patients highlight the pivotal role of tailored antithrombotic therapy in patients affected by cerebrovascular, aortic and lower extremity peripheral artery disease. Thus, the proper assessment of thrombotic and hemorrhagic risk in patients with PAD represents a key clinical challenge that must be met to permit the optimal antithrombotic prescription for the various clinical settings in daily practice. The aim of this updated review is to analyze different features of atherothrombotic disease as well as current evidence of antithrombotic management in asymptomatic and secondary prevention in PAD patients according to each arterial bed.

Abstract
Dual-antiplatelet therapy is commonly prescribed after endovascular intervention for peripheral artery disease. However, it is not known whether therapeutic anticoagulation affects outcomes after peripheral endovascular intervention. We sought to investigate whether therapeutic anticoagulation after peripheral endovascular intervention is associated with lower risk of major adverse limb events (MALEs) and all-cause mortality. We studied patients who underwent index endovascular intervention for peripheral artery disease in the Vascular Study Group of New England (2010 to 2018). The main exposure was anticoagulation at the time of discharge. Outcomes included patency loss (occlusion or target lesion reintervention), MALE (any major amputation or reintervention), and all-cause mortality. We compared outcomes between patients who received anticoagulation on discharge versus those who did not receive anticoagulation using Kaplan-Meier survival analysis and Cox regression. In the cohort of 6,809 patients, 15% were discharged on an anticoagulant (mostly warfarin). These patients had a higher prevalence of acute or chronic limb ischemia than those not receiving an anticoagulant (74% vs 47%, p < 0.001) and were less likely to receive any antiplatelet agent after peripheral endovascular intervention (5% vs 14%, p < 0.001). After risk adjustment, compared with patients not on an anticoagulant, patients receiving therapeutic anticoagulation had a higher risk of 2-year patency loss (hazard ratio [HR] 1.41, 95% confidence interval [CI] 1.05 to 1.89), MALE (HR 1.39, 95% CI 1.09 to 1.76), and all-cause mortality (HR 1.24, 95% CI 1.05 to 1.47). In conclusion, anticoagulation after peripheral endovascular intervention was associated with higher risk of adverse events, including patency loss, MALE, and all-cause mortality.

Abstract
BACKGROUND Clopidogrel is a cornerstone antiplatelet drug used in cardiovascular, cerebrovascular, and peripheral artery diseases. The sulfhydryl group of clopidogrel metabolite could induce insulin autoimmune syndrome (IAS) with hypoglycemia as the major symptom. Discontinuing clopidogrel and substituting it with ticagrelor has been revealed as an effective treatment in previous studies. Since hypoglycemia serves as a risk factor for cardiovascular and cerebrovascular events, we aimed to determine the association between hypoglycemia/IAS and clopidogrel and to investigate whether clopidogrel is a modifiable and causal risk factor of hypoglycemia/IAS. METHODS MEDLINE, Embase, Cochrane databases, and clinical trial registries were searched for randomized controlled trials (RCTs) of clopidogrel from inception to 28 February 2022. RCTs comparing clopidogrel with placebo or other antiplatelet drugs were eligible if meeting the inclusion criteria: 1) clopidogrel was administrated 75 mg qd orally as a long-term antiplatelet prescription at least for months, and 2) hypoglycemia-inducible drugs were not used in the control arm. One investigator abstracted articles and performed a quality assessment. Uncertainties were resolved by discussions with two investigators independently. Odds ratio (OR) and risk difference (RD) were calculated and performed with subgroup analyses. The pre-specified protocol was registered in PROSPERO (CRD42022299622). RESULTS Six trials with 61,399 participants in total fulfilled the criteria and were included in the meta-analysis. Clopidogrel might not be associated with higher hypoglycemia odds (OR 0.95, 95% CI 0.65 to 1.40). However, Asian participants (p = 0.0437) seemed more likely to develop clopidogrel-associated hypoglycemia. Clopidogrel-associated hypoglycemia occurred at the highest rate of 0.03% (RD -0.00023, 95% CI -0.00077 to 0.00031), and this increased to 0.91% (RD 0.00210, 95% CI -0.00494 to 0.00914) in an aging population and to 0.18% (RD 0.00040, 95% CI -0.00096 to 0.00177) when Asian ratio of the population was elevated. CONCLUSIONS We raise the concern that clopidogrel might be a modifiable and causal risk factor of hypoglycemia. The Asian population might be more vulnerable and need additional care.

Abstract
ZusammenfassungPatienten mit peripherer arterieller Verschlusskrankheit (pAVK) oder Aortenerkrankungen haben ein hohes Risiko für kardiovaskuläre Ereignisse. Gerinnungshemmende Medikamente verbessern die
Prognose und haben daher einen hohen Stellenwert. Bei jeder gerinnungshemmenden Therapie sollte das individuelle Blutungsrisiko berücksichtigt werden und eine individuelle
Nutzen-Risiko-Abwägung durchgeführt werden. Patienten mit symptomatischer pAVK sollten einen Thrombozytenaggregationshemmer (TZAH) erhalten. Bei hohem Risiko für kardiovaskuläre Ereignisse
und niedrigem Blutungsrisiko wird die Kombination von Acetylsalicylsäure (ASS) 100 mg und Rivaroxaban 2 × 2,5 mg empfohlen. Liegt ein hohes Blutungsrisiko vor, ist Clopidogrel ASS
vorzuziehen. Bei Patienten mit Aortenerkrankungen (z. B. komplexe Plaques, Aortenaneurysma) ist die Gabe eines TZAH indiziert. Patienten mit einer atherosklerotischen Gefäßerkrankung und
Indikation für eine orale Antikoagulation wegen Vorhofflimmern oder venöser Thromboembolie sollten keinen zusätzlichen TZAH erhalten. Denn dieser erhöht das Blutungsrisiko, ohne die Prognose
zu verbessern.

Abstract
Peripheral artery disease (PAD) is a clinical manifestation of atherosclerotic disease with a large-scale impact on the economy and global health. Despite the role played by platelets in the process of atherogenesis being well recognized, evidence has been increasing on the contribution of the coagulation system to the atherosclerosis formation and PAD development, with important repercussions for the therapeutic approach. Histopathological analysis and some clinical studies conducted on atherosclerotic plaques testify to the existence of different types of plaques. Likely, the role of coagulation in each specific type of plaque can be an important determinant in the histopathological composition of atherosclerosis and in its future stability. In this review, we analyze the molecular contribution of inflammation and the coagulation system on PAD pathogenesis, focusing on molecular similarities and differences between atherogenesis in PAD and coronary artery disease (CAD) and discussing the possible implications for current therapeutic strategies and future perspectives accounting for molecular inflammatory and coagulation targets. Understanding the role of cross-talking between coagulation and inflammation in atherosclerosis genesis and progression could help in choosing the right patients for future dual pathway inhibition strategies, where an antiplatelet agent is combined with an anticoagulant, whose role, despite pathophysiological premises and trials' results, is still under debate.

Abstract
Peripheral artery disease (PAD) commonly refers to atherosclerotic narrowing of noncoronary arteries, primarily those supplying the lower extremities. The risk factors for PAD include smoking, hyperlipidemia, hypertension, and diabetes mellitus. Patients with PAD are at a heightened risk of major adverse cardiovascular events (including myocardial infarction, stroke, and cardiovascular death) and major adverse limb events (including progressive symptoms or limb ischemia requiring peripheral revascularization, amputation, and acute limb ischemia), highlighting the need for guideline-directed therapies. Lifestyle modifications and medical therapies are utilized to improve function and outcomes in this patient population. Adherence to a healthy diet and smoking cessation are both associated with better outcomes in patients with PAD. Medical therapies targeting axes of risk, including lipid-modifying therapies, antithrombotic therapies, and targeted diabetes therapies, are available to reduce this risk in patients with PAD; however, significant residual risk remains. Unfortunately, despite guideline recommendations and efforts at education, even available medical therapies remain underutilized in patients with PAD. Continued development of novel therapies and efforts to improve the provision of care in patients with PAD are needed.

Espinola-Klein C, Weißer G, Schmitt V, Schwaderlapp M, Munzel T. Antithrombotic therapy in peripheral arterial disease. Front Cardiovasc Med 2022; 9:927645. [PMID: 36312276 PMCID: PMC9606411 DOI: 10.3389/fcvm.2022.927645] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2022] [Accepted: 08/19/2022] [Indexed: 12/24/2022] Open
Abstract
Background Patients with peripheral arterial disease (PAD) are at increased risk for major adverse cardiovascular events (MACE) such as cardiovascular death, myocardial infarction, and stroke as well as major adverse limb events (MALE) such as amputation and acute limb ischemia. Therefore, prevention of thrombotic events is crucial to improve the prognosis of PAD patients. This review article concludes current evidence and guideline recommendations about antithrombotic therapy in PAD patients.Antithrombotic therapy is highly effective to reduce MACE and MALE events in PAD patients. Recently, the concept of dual pathway inhibition (low-dose rivaroxaban plus acetylic salicylic acid (ASA) has been tested in the COMPASS and VOYAGER-PAD trial. Compared to ASA alone dual pathway inhibition was superior to prevent MACE and MALE. After peripheral revascularization, in particular the risk for acute limb ischemia was reduced. In contrast, the risk for major bleeding is increased. Therefore, current guidelines recommend the combination of low-dose rivaroxaban and ASA in PAD patients with low bleeding risk. In patients with high bleeding risk, a single antiplatelet drug (preferable clopidogrel) is indicated. In patients with atherosclerotic vascular disease and indication for oral anticoagulation, no additional antiplatelet drug is necessary, as this would increase the risk of bleeding without improving the prognosis. Conclusion Antithrombotic treatment reduces MACE and MALE and is recommended in all patients with PAD. Individual bleeding risk should always be considered based on the current data situation and an individual benefit-risk assessment must be carried out.

Antithrombotic Therapy for Symptomatic Peripheral Arterial Disease: A Systematic Review and Network Meta-Analysis. Drugs 2022; 82:1287-1302. [PMID: 35997941 PMCID: PMC9499921 DOI: 10.1007/s40265-022-01756-6] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 07/24/2022] [Indexed: 12/24/2022]
Abstract
BACKGROUND High-quality evidence from trials directly comparing single antiplatelet therapies in symptomatic peripheral arterial disease (PAD) to dual antiplatelet therapies or acetylsalicylic acid (ASA) plus low-dose rivaroxaban is lacking. Therefore, we conducted a network meta-analysis on the effectiveness of all antithrombotic regimens studied in PAD. METHODS A systematic search was conducted to identify randomized controlled trials. The primary endpoints were major adverse cardiovascular events (MACE) and major bleedings. Secondary endpoints were major adverse limb events (MALE) and acute limb ischaemia (ALI). For each outcome, a frequentist network meta-analysis was used to compare relative risks (RRs) between medication and ASA. ASA was the universal comparator since a majority of studies used ASA as in the reference group. RESULTS Twenty-four randomized controlled trials were identified including 48,759 patients. With regard to reducing MACE, clopidogrel [RR 0.78, 95% confidence interval (CI) 0.66-0.93], ticagrelor (RR 0.79, 95% CI 0.65-0.97), ASA plus ticagrelor (RR 0.79, 95% CI 0.64-0.97), and ASA plus low-dose rivaroxaban (RR 0.84, 95% CI 0.76-0.93) were more effective than ASA, and equally effective to one another. As compared to ASA, major bleedings occurred more frequently with vitamin K antagonists, rivaroxaban, ASA plus vitamin K antagonists, and ASA plus low-dose rivaroxaban. All regimens were similar to ASA concerning MALE, while ASA plus low-dose rivaroxaban was more effective in preventing ALI (RR 0.67, 95% CI 0.55-0.80). Subgroup analysis in patients undergoing peripheral revascularization revealed that ≥ 3 months after intervention, evidence of benefit regarding clopidogrel, ticagrelor, and ASA plus ticagrelor was lacking, while ASA plus low-dose rivaroxaban was more effective in preventing MACE (RR 0.87, 95% CI 0.78-0.97) and MALE (RR 0.89, 95% CI 0.81-0.97) compared to ASA. ASA plus clopidogrel was not superior to ASA in preventing MACE ≥ 3 months after revascularization. Evidence regarding antithrombotic treatment strategies within 3 months after a peripheral intervention was lacking. CONCLUSION Clopidogrel, ticagrelor, ASA plus ticagrelor, and ASA plus low-dose rivaroxaban are superior to ASA monotherapy and equally effective to one another in preventing MACE in PAD. Of these four therapies, only ASA plus low-dose rivaroxaban provides a higher risk of major bleedings. More than 3 months after peripheral vascular intervention, ASA plus low-dose rivaroxaban is superior in preventing MACE and MALE compared to ASA but again at the cost of a higher risk of bleeding, while other treatment regimens show non-superiority. Based on the current evidence, clopidogrel may be considered the antithrombotic therapy of choice for most PAD patients, while in patients who underwent a peripheral vascular intervention, ASA plus low-dose rivaroxaban could be considered for the long-term (> 3 months) prevention of MACE and MALE.

Abstract
Effective revascularization of peripheral artery disease relies on periprocedural pharmacological regulation of the clotting cascade. Patient-specific factors such as cardiovascular risk factors, contraindications, and individual psychosocial factors must be considered when initiating post revascularization management. Management with anticoagulant and antiplatelet agents is discussed to guide the interventionalist on which therapy may be appropriate for their patient. While exact treatment may be institution and provider dependent, the interventionist must be familiar with the available classes of medications and how they can be prescribed in the postprocedural setting to improve cardiovascular outcomes.

Abstract
To prevent atherothrombotic events, patients with peripheral arterial disease are typically prescribed antiplatelet therapy (APT). However, some of them receive anticoagulant therapy (ACT) due to comorbidities. Our aim was to determine possible differences in the effectiveness and safety of both treatments in patients after endovascular femoropopliteal revascularisation. We retrospectively analysed 1247 patients after successful femoropopliteal revascularisation performed in a single tertiary medical centre and classified them into the ACT or APT group, based on their prescribed treatment. The groups were characterised by descriptive statistics, and their characteristics were adjusted for confounders by propensity score matching. Effectiveness and safety outcomes were assessed within one year after revascularisation. The odds ratio for the composite outcome of all-cause death, PAD exacerbation, and major amputation due to vascular causes with ACT versus APT was 1.21 (95% CI 0.53–2.21; p = 0.484). The odds ratio for major bleeding as defined by the International Society on Thrombosis and Haemostasis with ACT versus APT was 0.77 (95% CI 0.13–3.84; p = 0.251). We found no statistically significant difference in the effectiveness and safety of ACT, when compared to APT in patients with similar cardiovascular risk factors and other baseline characteristics. Further prospective research is warranted.

Mono or Dual Antiplatelet Therapy for Treating Patients with Peripheral Artery Disease after Lower Extremity Revascularization: A Systematic Review and Meta-Analysis. Pharmaceuticals (Basel) 2022; 15:ph15050596. [PMID: 35631422 PMCID: PMC9144146 DOI: 10.3390/ph15050596] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2022] [Revised: 05/02/2022] [Accepted: 05/09/2022] [Indexed: 12/24/2022] Open
Abstract
The efficacy of dual antiplatelet therapy (DAPT) for patients with peripheral artery disease (PAD) after lower-limb intervention remains controversial. Currently, the prescription of DAPT after an intervention is not fully recommended in guidelines due to limited evidence. This study compares and analyzes the prognosis for symptomatic PAD patients receiving DAPT versus monotherapy after lower-limb revascularization. Up to November 2021, PubMed/MEDLINE, Embase, and Cochrane databases were searched to identify studies reporting the efficacy, duration, and bleeding complications when either DAPT or monotherapy were used to treat PAD patients after revascularization. Three randomized controlled trials and seven nonrandomized controlled trials were included in our study. In total, 74,651 patients made up these ten studies. DAPT in PAD patients after intervention was associated with lower rates of all-cause mortality (HR = 0.86; 95% CI, 0.79−0.94; p < 0.01), major adverse limb events (HR = 0.60; 95% CI, 0.47−0.78; p < 0.01), and major amputation (HR = 0.78; 95% CI, 0.64−0.96) when follow-up was for more than 1-year. DAPT was not associated with major bleeding events when compared with monotherapy (OR = 1.22; 95% CI, 0.69−2.18; p = 0.50) but was associated with a higher rate of minor bleeding as a complication (OR = 2.54; 95% CI, 1.59−4.08; p < 0.01). More prospective randomized studies are needed to provide further solid evidence regarding the important issue of prescribing DAPT.

Edoxaban versus Warfarin in high-risk patients with atrial fibrillation: A comprehensive analysis of high-risk subgroups. Am Heart J 2022; 247:24-32.

Abstract
BACKGROUND To compare the efficacy and safety of edoxaban vs warfarin in high-risk subgroups. METHODS ENGAGE AF-TIMI 48 was a multicenter randomized, double-blind, controlled trial in 21,105 patients with atrial fibrillation (AF) within 12 months and CHADS2 score >2 randomized to higher-dose edoxaban regimen (HDER) 60 mg/reduced 30 mg, lower-dose edoxaban regimen (LDER) 30 mg/reduced 15 mg, or warfarin, and followed for 2.8 years (median). The primary outcome for this analysis was the net clinical outcome (NCO), a composite of stroke/systemic embolism events, major bleeding, or death. Multivariable risk-stratification analysis was used to categorize patients by the number of high-risk features. RESULTS The annualized NCO rates in the warfarin arm were highest in patients with malignancy (19.2%), increased fall risk (14.0%), and very-low body weight (13.5%). The NCO rates increased with the numbers of high-risk factors in the warfarin arm: 4.5%, 7.2%, 9.9% and 14.6% in patients with 0 to 1, 2, 3, and >4 risk factors, respectively (Ptrend <0.001). Versus warfarin, HDER was associated with significant reductions of NCO in most of the subgroups: elderly, patients with moderate renal dysfunction, prior stroke/TIA, of Asian race, very-low body weight, concomitant single antiplatelet therapy, and VKA-naïve. With more high-risk features (0->4+), the absolute risk reductions favoring edoxaban over warfarin increased: 0.3%->2.0% for HDER; 0.4%->3.4% for LDER vs warfarin (P = .065 and P < .001, respectively). CONCLUSIONS While underuse of anticoagulation in high-risk patients with AF remains common, substitution of effective and safer alternatives to warfarin, such as edoxaban, represents an opportunity to improve clinical outcomes.

Abstract
Patients with widespread atherosclerosis such as peripheral artery disease (PAD) have a high risk of cardiovascular and limb symptoms and complications, which affects their quality of life and longevity. Over the past 2 decades there have been substantial advances in diagnostics, pharmacotherapy, and interventions including endovascular and open surgical to aid in the management of PAD patients. To summarize the evidence regarding approaches to diagnosis, risk stratification, medical and intervention treatments for patients with PAD, guided by the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) framework, evidence was synthesized, and assessed for quality, and recommendations provided-categorized as weak or strong for each prespecified research question. Fifty-six recommendations were made, with 27% (15/56) graded as strong recommendations with high-quality evidence, 14% (8/56) were designated as strong recommendations with moderate-quality evidence, and 20% (11/56) were strong recommendations with low quality of evidence. Conversely 39% (22/56) were classified as weak recommendations. For PAD patients, strong recommendations on the basis of high-quality evidence, include smoking cessation interventions, structured exercise programs for claudication, lipid-modifying therapy, antithrombotic therapy with a single antiplatelet agent or dual pathway inhibition with low-dose rivaroxaban and aspirin; treatment of hypertension with an angiotensin converting enzyme or angiotensin receptor blocker; and for those with diabetes, a sodium-glucose cotransporter 2 inhibitor should be considered. Furthermore, autogenous grafts are more effective than prosthetic grafts for surgical bypasses for claudication or chronic limb-threatening ischemia involving the popliteal or distal arteries. Other recommendations indicated that new endovascular techniques and hybrid procedures be considered in patients with favourable anatomy and patient factors, and finally, the evidence for perioperative risk stratification for PAD patients who undergo surgery remains weak.

Abstract
Peripheral arterial disease (PAD) represents a major health issue that significantly impacts patient's survival and quality of life. In addition to limb-related events, patients with PAD have an increased risk of myocardial infarction, stroke, and death. However, compared with coronary and cerebrovascular disease, studies addressing optimal risk reduction modalities including antithrombotic therapies in patients with PAD have been underrepresented in the literature. This publication serves as a narrative review of existing evidence on the effectiveness of antithrombotic therapy in patients with PAD. In patients with chronic stable PAD or post-revascularization, antithrombotic therapies including single or dual antiplatelet agents, anticoagulation, or a combination of these treatments have been shown to reduce cardiovascular and limb events. This narrative review provides a summary of the available literature on the management of patients with PAD, categorized into treatment strategies for chronic, post-endovascular treatment, and post-open surgical revascularization and to discuss the antithrombotic protocol utilized at our institution while providing a rational for our treatment algorithm.

Latest outcomes of transcatheter left atrial appendage closure devices and direct oral anticoagulant therapy in patients with atrial fibrillation over the past 5 years: a systematic review and meta-analysis. Cardiovasc Interv Ther 2022; 37:725-738.

Abstract
Left atrial appendage closure (LAAC) are emerging treatment for patients with atrial fibrillation (AF). However, data on the safety, efficacy, and medications for LAAC devices in patients with AF are lacking. We aimed to investigate the incidence of all-cause mortality, stroke, and major bleeding in AF patients with LAAC devices and DOACs. Moreover, we aimed to investigate the incidence rate of device-related thrombus (DRT) and the medications used in the management of AF patients with LAAC devices to gain insights into achieving better outcome. Based on a literature search using PubMed, EMBASE, Cochrane Library, and Web of Science databases between January 2015 and December 2020, eight LAAC device studies that used WATCHMAN and Amulet, and three DOAC studies that used rivaroxaban, with a total of 24,055 AF patients (LAAC devices, n = 2855; DOAC, n = 21,200), were included. A random-effects model was used to incorporate heterogeneity among studies. The pooled incidence of events per person-years were as follows: all-cause mortality, 0.06 (95% confidence interval [CI] 0.02-0.10) for WATCHMAN, 0.04 (95% CI 0.00-0.14) for Amulet, and 0.03 (95% CI 0.01-0.04) for rivaroxaban; stroke; 0.02 (95% CI 0.00-0.04) for WATCHMAN, 0 for Amulet, and 0.01 (95% CI 0.01-0.02) for rivaroxaban; major bleeding, 0.04 (95% CI 0.02-0.06) for WATCHMAN, 0.02 (95% CI 0.00-0.06) for Amulet, and 0.02 (95% CI 0.01-0.03) for rivaroxaban. The incidence rate of DRT was 2.3%, and complications were reported in 9%. The incidence of all-cause mortality, stroke, and major bleeding were similar between LAAC devices and DOACs. The rate of complications was acceptable, and those of DRT were lower than the average incidence reported in previous studies. However, further follow-up is needed. Concomitant anticoagulant and antiplatelet therapies should be further evaluated to find the optimal regimen for AF patients with LAAC devices.

Abstract
PURPOSE OF REVIEW To provide an overview of new concepts in the pharmacotherapy of patients with peripheral artery disease (PAD). RECENT FINDINGS Modern therapeutic strategies for patients with PAD include specific symptom management and multidisciplinary prevention of cardiovascular events. Low-dose rivaroxaban in combination with aspirin improves outcomes compared with aspirin monotherapy among patients with PAD. Other novel concepts include the use of bosentan, vorapaxar or sildenafil among symptomatic patients with PAD. Likewise, lipid-lowering therapy reduces the risk of major cardiovascular and limb events. SUMMARY Personalized management, identification of risk factors and shared-decision making are crucial in improving the best medical therapy for patients with PAD. Further studies are needed to assess the long-term safety and efficacy of novel strategies in real-world patients.

Chen X, Huang W, Sun A, Wang L, Mo F, Guo W. Bleeding risks with novel oral anticoagulants especially rivaroxaban versus aspirin: a meta-analysis. Thromb J 2021; 19:69. [PMID: 34600549 PMCID: PMC8487538 DOI: 10.1186/s12959-021-00322-6] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2021] [Accepted: 09/19/2021] [Indexed: 11/23/2022] Open
Abstract
Background This pairwise meta-analysis determines the difference in bleeding risks associated with the use of novel oral anticoagulants (NOACs) and aspirin. Methods PubMed, the Cochrane Library database, clinicaltrial.gov, and related studies were searched for randomized control trials (RCTs) comparing NOAC and aspirin published between January 1, 2000 and May 10, 2021. The primary endpoint was intracranial hemorrhage (ICH). Results Eleven studies involving 57,645 patients were included. Compared to aspirin, rivaroxaban (5 mg/day) had a similar risk of ICH, major bleeding, and fatal bleeding; rivaroxaban (10 mg/day) had higher risks of gastrointestinal hemorrhage (OR: 1.41; 95% CI: 1.03–1.94; P = 0.032; I2 = 0%) and a similar risk of ICH, major bleeding, and fatal bleeding; and rivaroxaban (15–20 mg/day) had higher risks of ICH (OR: 3.21; 95% CI: 1.36–7.60; P = 0.008; I2 = 0%), major bleeding (OR: 2.64; 95% CI: 1.68–4.16; P < 0.001; I2 = 0%), and fatal bleeding (OR: 2.26; 95% CI: 1.25–4.08; P = 0.007; I2 = 0%) and a similar risk of gastrointestinal hemorrhage. Bleeding outcomes between other NOACs (apixaban and dabigatran etexilate) and aspirin were not different. Conclusions The bleeding risks associated with NOACs depend on drug type and dosage. For ≥15 mg/day of rivaroxaban, the risk of ICH was significantly higher than that with aspirin. However, further studies comparing dabigatran etexilate and apixaban versus aspirin are warranted to draw a definite conclusion.

Antithrombotic Therapy in Peripheral Artery Disease: Stepping in the Right Direction. Am J Cardiovasc Drugs 2021; 21:523-534.

Abstract
We reviewed the various antithrombotic therapies available to treat peripheral artery disease (PAD). A literature review using the PubMed and MEDLINE databases used the following keywords: antithrombotic therapy, anticoagulation, peripheral artery disease, and peripheral vascular disease. Randomized studies written in English that assessed the use of antithrombotic therapy in patients with PAD were evaluated. PAD is a worldwide condition that limits blood flow in the lower extremities, leading to a risk of major adverse cardiovascular events and major adverse limb events. Antithrombotic therapy is necessary to prevent these complications, and the choice of therapy depends upon the stage of disease progression. For symptomatic patients in the beginning stage, single antiplatelet therapy (SAPT) is the preferred therapy, specifically, aspirin. For patients undergoing endovascular revascularization, the preferred therapy is dual antiplatelet therapy using aspirin and clopidogrel combined for at least the first month followed by long-term SAPT. For patients undergoing surgical revascularization, the preferred choice of therapy depends upon the type of graft used, with better results obtained with antiplatelet therapy for prosthetic grafts and anticoagulation for venous grafts. New studies have shown that therapy using both antiplatelets and anticoagulation in the form of aspirin plus low-dose rivaroxaban can reduce complications in all three patient populations, which has paved the way for future studies featuring direct oral anticoagulants with the potential to change current guideline recommendations.

Abstract
In the past decade, direct oral anticoagulants (DOACs) have transformed the world of anti-thrombotic therapy. Edoxaban is the most recently approved DOAC. Though intended for use primarily in stroke prevention, it has found applications in various other conditions including thromboembolic and peripheral arterial disease. This review aims to provide a detailed outline of the growing indications, evidence for use in special populations, pharmacogenetics, and side effect profile of edoxaban.

Abstract
The aim of this collaborative document is to provide an update for clinicians on best antithrombotic strategies in patients with aortic and/or peripheral arterial diseases. Antithrombotic therapy is a pillar of optimal medical treatment for these patients at very high cardiovascular risk. While the number of trials on antithrombotic therapies in patients with aortic or peripheral arterial diseases is substantially smaller than for those with coronary artery disease, recent evidence deserves to be incorporated into clinical practice. In the absence of specific indications for chronic oral anticoagulation due to concomitant cardiovascular disease, a single antiplatelet agent is the basis for long-term antithrombotic treatment in patients with aortic or peripheral arterial diseases. Its association with another antiplatelet agent or low-dose anticoagulants will be discussed, based on patient's ischaemic and bleeding risk as well therapeutic paths (e.g. endovascular therapy). This consensus document aims to provide a guidance for antithrombotic therapy according to arterial disease localizations and clinical presentation. However, it cannot substitute multidisciplinary team discussions, which are particularly important in patients with uncertain ischaemic/bleeding balance. Importantly, since this balance evolves over time in an individual patient, a regular reassessment of the antithrombotic therapy is of paramount importance.

Abstract
Peripheral artery disease (PAD) is a major cause of morbidity and mortality but it is usually underdiagnosed and undertreated. Patients with PAD present dysregulated procoagulant, anticoagulant, and fibrinolytic pathways leading to arterial and venous thrombosis. The risk of several ischemic-related complications could be mitigated with appropriate antithrombotic therapy, which plays a central role in all types of PAD. For years, antiplatelets have been indicated in patients with symptomatic PAD or those who have undergone revascularization. Unfortunately, a non-negligible proportion of patients with PAD will suffer from adverse events during the follow-up, even despite proper medical therapies for the prevention of PAD complications. Thus, there is room for improving clinical outcomes in these patients. Given the implication of both, primary and secondary hemostasis in arterial thrombosis and the pathophysiology of PAD, the combination of antiplatelets and anticoagulants has emerged as a potential antithrombotic alternative to antiplatelets alone. In this narrative review article, we have highlighted the most recent evidence about antithrombotic therapy in PAD patients, with a special focus on oral anticoagulation. Certainly, COMPASS and VOYAGER PAD trials have shown promising results. Thus, rivaroxaban in combination with aspirin seem to reduce cardiovascular outcomes with a similar bleeding risk compared to aspirin alone. Nevertheless, results from real-world studies are needed to confirm these observations, and other trials will provide novel evidence about the safety and efficacy of emerging anticoagulant agents.

Abstract
Peripheral artery disease (PAD) remains a major cause of morbidity and future cardiovascular events despite advancement in the surgical interventions and optimal medical therapy. The aim of our study is to evaluate the efficacy and safety of anticoagulation (AC) therapy for reducing cardiovascular and limb events in patients with PAD. PUBMED, Medline, and Cochrane Library were searched through 2020 for randomized clinical trials comparing major adverse cardiovascular events (MACE) and risk of major bleeding (MB), between AC and standard of care (SOC) therapy, among patients with PAD. Meta-analysis was performed using weighted pooled absolute risk difference (RD) with 95% confidence interval (CI) and fixed effects model for overall and sub-groups of full dose (FD) and low dose (LD) AC therapies. Amongst 17,684 patients from 7 different studies, the addition of AC to SOC therapy was associated with MACE reduction (RD -0.022, 95% CI -0.033 to -0.012, p <0.001) and increased MB (RD 0.02, 95% CI 0.014 to 0.025, p <0.001). For FD, MACE reduction was (RD -0.021, 95% CI -0.042 to 0.001, p = 0.061) and MB (RD 0.036, 95% CI 0.025 to 0.047, p <0.001). For LD, MACE reduction was (RD -0.023, 95% CI -0.035 to -0.011, p <0.001) and MB (RD 0.011, 95% CI 0.005 to 0.017, p <0.001). In conclusion, addition of AC to the current SOC therapy can mitigate future MACE events in patients with PAD albeit at risk of increased bleeding. LD AC is associated with an efficacy/safety net benefit compared to FD AC therapy.

Abstract
AIMS To evaluate the safety and effectiveness of fondaparinux in addition to dual antiplatelet therapy (DAPT) in patients with critical limb-threatening ischaemia (CLTI). METHODS Fondaparinux (2.5 mg/d) was administered for 1-4 weeks after endovascular procedures together with DAPT (fondaparinux arm). Patients who received standard DAPT were retrospectively matched and generated the control arm. Demographic, angiographic and follow-up data, including (i) clinically relevant bleeding and (ii) target vessel revascularisation or major amputation after 12 months was analysed. RESULTS Twenty-four patients (78.7 ± 6.9 years, 14 [58%] female, 4 TASC B, 10 TASC C and 10 TASC D lesions, total lesion length = 210 ± 98 mm, mean Rutherford class = 4.7 ± 0.6) received fondaparinux (over a period of 22 ± 9 d, range 7-28 d) and DAPT versus 24 control patients who received standard DAPT (78.3 ± 8.4 years, 14 [58%] female, 4 TASC B, 8 TASC C and 12 TASC D lesions, total lesion length = 204 ± 73 mm, mean Rutherford class = 4.6 ± 0.6). During follow-up, 3(13%) patients in the fondaparinux arm exhibited significant bleeding versus 5 (21%) in the control arm (p = ns). Four (17%) patients of the fondaparinux arm underwent target vessel revascularisation or major amputation versus 6 (25%) in the control group (p = ns). CONCLUSIONS Adding fondaparinux to DAPT does not seem to result in excess of clinically relevant bleeding. Our preliminary data suggest that prospective studies are now warranted in larger patient cohorts. GERMAN CLINICAL TRIALS REGISTER DRKS00015856.

Abstract
Cardiovascular diseases including coronary heart disease, stroke, and peripheral arterial disease were responsible for an estimated 18 million deaths in 2017. Despite advances in management over the past several decades, these patients continue to have substantial risk of subsequent cardiovascular events. We provide a narrative review of randomized clinical trials evaluating direct oral anticoagulants (DOACs) for the treatment of acute coronary syndromes, noncardioembolic ischemic stroke, embolic stroke of undetermined source, and peripheral arterial disease. In these conditions, considerations for use of single antiplatelet therapy, dual antiplatelet therapy, or low-dose DOACs used together with antiplatelet therapy are presented.

Abstract
Evidence for antithrombotic treatment following lower extremity revascularization (LER) for peripheral artery disease (PAD) is limited, leading to weak and conflicting guideline recommendations and heterogeneous practice patterns. This variability in post-LER antithrombotic treatment raises quality-of-care issues that have long been under-studied. This Viewpoint reviews the most updated guidelines, currently-available evidence, and contemporary data about practice patterns and practitioner opinions in this area. Particular attention is paid to distinctions between antiplatelet therapy, anticoagulant therapy, and combination therapy in light of the recent VOYAGER-PAD (Vascular Outcomes Study of ASA [acetylsalicylic acid] Along with Rivaroxaban in Endovascular or Surgical Limb Revascularization for PAD) trial. The implications of VOYAGER-PAD pertaining to various subgroups of patients undergoing LER are explored. Overall, this Viewpoint argues for consideration of post-LER therapy targeted at both platelet function and the coagulation cascade, though further LER-specific analyses, including expected VOYAGER-PAD sub-analyses, are needed.

Abstract
BACKGROUND The efficacy and safety of non-vitamin K antagonist oral anticoagulants (NOACs) combined with antiplatelet drugs in patients with peripheral artery disease remain largely unknown. OBJECTIVE The aim of this meta-analysis was to explore the effects of NOACs combined with antiplatelet drugs versus antiplatelet drugs alone in this population. METHODS A comprehensive search of randomized controlled trials published in PubMed, EMBASE, Web of Science, and the Cochrane Library in 30 September 2020 and before. According to the I2 statistic, a random or fixed-effect model was used to analyze the safety and effectiveness of NOACs combined with antiplatelet drugs in peripheral artery disease patients. RESULTS Three RCTs met the inclusion criteria, with a total sample size of 11,761 participants. Compared with antiplatelet drugs alone, NOACs combined with antiplatelet drugs resulted in lower risk of ischemic stroke events (OR = 0.75, 95%CI 0.57-0.98, p = 0.03), while other treatment effects were not worse than those of single antiplatelet drugs (p ≥ 0.05). In addition, although compared with single antiplatelet drugs alone, NOACs combined with antiplatelet drugs had a higher risk of major bleeding and clinically related nonmajor bleeding, their risk was not higher for intracranial hemorrhage, which may endanger the life of patients, or for fatal bleeding. CONCLUSIONS In summary, for peripheral artery disease patients, a combination of NOACs plus antiplatelet drugs may offer additional benefit in reducing ischemic stroke outcome, yet it may increase the risk of bleeding.

Abstract
Patients with lower extremity peripheral artery disease (PAD) are at increased risk of major adverse limb events (MALE). The efficacy and safety of direct oral anticoagulants (DOACs) in this context is evolving. To assess the efficacy and safety of DOAC combined with aspirin compared to the use of antiplatelet agents in patients with symptomatic lower extremity (LE) PAD. We systematically searched PubMed, Embase and Cochrane databases, in September 2020, for randomized controlled trials (RCTs) that were designed to investigate the effect of DOACs in the treatment of PAD. A random-effects meta-analysis was performed targeting ischemic and bleeding events. Three randomized clinical trials were included, providing a total of 9533 patients, and 744 pooled MALE events (316 in DOAC plus aspirin and 428 in control). Only data on rivaroxaban and edoxaban were available. The use of DOAC plus aspirin in PAD patients significantly decreased the rate of MALE (pooled OR 0.70 [0.61-0.83], P < 0.001; I2 = 0%). In terms of safety, there was a significantly higher rate of major bleeding events (pooled OR 1.46 [1.16-1.84], P = 0.001; I2 = 52%). In rivaroxaban-RCTs, the addition of low-dose rivaroxaban to aspirin was still associated with a lower MALE compared to aspirin alone (pooled OR 0.68 [0.53-0.88], P = 0.003; I2 = 28%), but also conferred higher major bleeding rate (pooled OR 1.48 [1.18-1.86], P < 0.001; I2 = 0%). In conclusion, our pooled data suggests that for patients with symptomatic LE-PAD, the use of DOAC combined with aspirin reduced the risk of major ischemic limb events at the expense of an increased risk of major bleeding.

Abstract
Critical limb ischemia (CLI) constitutes the most advanced form of peripheral artery disease (PAD) and is characterized by ischemic rest pain, tissue loss and/or gangrene. Optimized medical care and risk factor modification in addition to revascularization could reduce the incidence of cardiovascular events and major adverse limb events, improving patients' quality of life and promising higher survival rates. Adequate adherence to cardioprotective medications, including antithrombotic therapy (e.g., antiplatelets, anticoagulants), cholesterol-lowering agents (e.g., statins, proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors), angiotensin-converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARBs), and smoking cessation should be strongly encouraged for patients with CLI. This review examines these guideline-recommended therapies in terms of cardiovascular and limb-related risk reduction in patients with CLI.

Abstract
Background: This study aims to explore the role of low-dose rivaroxaban (≤10 mg daily) for the treatment of atherosclerotic cardiovascular disease (ASCVD). Methods: PubMed, Embase and the Cochrane Library were searched for randomized controlled trials (RCTs) of low-dose rivaroxaban in patients with ASCVD including coronary artery disease (CAD) and peripheral artery disease (PAD). Literature screening, data extraction, and risk of bias assessment were carried out independently by two researchers. Hazard ratio (HR) and 95% confidence interval (CI) were calculated using random-effect models to determine risks of outcomes in ASCVD patients treated with rivaroxaban and comparators, and meta-analysis was conducted via Review Manager 5.3.5 software. Results: 3,768 records were obtained through literature search, and 9 articles representing 6 RCTs ultimately qualified for this study. The meta-analysis indicated that for patients with CAD, the addition of rivaroxaban (5 mg daily) to aspirin could significantly reduce the risk of major adverse cardiovascular events (MACEs) compared with aspirin alone (HR 0.81, 95% CI, 0.72 to 0.91, p = 0.0004, I2 = 60%, 4 studies). For PAD patients receiving rivaroxaban (5 mg daily) plus aspirin, there was no significant reduction in the risk of MACEs (HR 0.84, 95% CI, 0.63 to 1.13, p = 0.25, I2 = 74%, 2 studies); however, there was significant reduction in major adverse limb events (MALEs) (HR 0.54, 95% CI, 0.35 to 0.83, p = 0.005, one studies) and in the composite of MACEs or MALEs (HR 0.78, 95% CI, 0.64 to 0.95, p = 0.02, I2 = 66%, 2 studies) when compared with patients receiving aspirin alone. Meanwhile, rivaroxaban combined with aspirin significantly increased the risk of International Society on Thrombosis and Haemostasis (ISTH) major bleeding compared with aspirin alone in patients with CAD (HR 1.74, 95% CI, 1.43 to 2.13, p < 0.00001, I2 = 0%, 2 studies) and PAD (HR 1.47, 95% CI, 1.19 to 1.83, p = 0.0004, I2 = 0%, 2 studies). Conclusions: Compared with standard antiplatelet therapy, the addition of a 5 mg daily dose of rivaroxaban to standard antiplatelet therapy may improve cardiovascular or limb outcomes of patients with ASCVD, with an increase in major bleeding. Patients who would benefit from the addition of low-dose rivaroxaban to antiplatelet agents and appropriate dual-pathway antithrombotic strategies should be identified in clinical practice to individualize antithrombotic therapy.

Abstract
Patients with lower extremity arterial disease are at increased risk for cardiovascular events. Antithrombotic therapy improves prognosis in these patients especially after peripheral revascularization. After endovascular revascularization duale anti-platelet therapy with Aspirin and Clopidogrel is used for up to 3 months in most cases, although there is only little evidence for this practice. Following peripheral bypass grafting most guidelines recommend single anti-platelet therapy. In some patients, anticoagulation with Vitamin K antagonists or dual anti-platelet therapy is indicated. But this practice is also based on small studies. The Vascular Outcomes Study of ASA Along With Rivaroxaban in Endovascular or Surgical Limb Revascularization for Peripheral Artery Disease (VOYAGER PAD) study is the largest randomized trial concerning antithrombotic therapy after peripheral revascularization. In total 6564 patients were included after successful surgical or endovascular lower-extremity revascularization. Rivaroxaban 2.5 mg twice daily plus Aspirin 100 mg reduced cardiac and peripheral events compared with Aspirin 100 mg alone with increased risk for relevant but not for critical bleeding complications. In addition to antithrombotic medication risk factor management and regular follow-up examinations are important improve long-term prognosis after peripheral revascularization.

Abstract
BACKGROUND The efficacy and safety of direct oral anticoagulants (DOACs) in patients with peripheral arterial disease are not completely understood. Therefore, we conducted a meta-analysis to explore the effects of DOACs in this population. METHODS We systematically searched the PubMed, Cochrane Library, and Web of Science till April 2020 for relevant randomized controlled trials and observational studies, with no linguistic restrictions. The efficacy outcomes were cardiovascular death, stroke, myocardial infraction, major adverse cardiovascular events (MACE), acute limb ischemia, amputation, and target lesion revascularization. The safety outcome was major bleeding events. Random effects risk ratios with 95% confidence intervals were calculated. RESULTS A total four randomized controlled trials were included in this meta-analysis. Among peripheral arterial disease patients, DOACs did not reduce the risk of cardiovascular death (RR = 1.02 95%CI 0.75-1.37, P = 0.92), stroke (RR = 0.73 95%CI 0.46-1.14, P = 0.16), myocardial infraction (RR = 0.85 95%CI 0.70-1.03, P = 0.10), MACE (RR = 0.73 95%CI 0.46-1.14, P = 0.16), or amputation (RR = 0.73 95%CI 0.46-1.14, P = 0.16) compared with control. However, DOACs were associated with reduction in acute limb ischemia (RR = 0.67 95%CI 0.55-0.80, P < 0.01) and target lesion revascularization (RR = 0.89 95%CI 0.81-0.99, P = 0.02) at the expense of major bleeding events (RR = 1.43 95%CI 1.16-1.77, P < 0.01) compared with control. CONCLUSIONS Based on current evidence, no significant difference in cardiovascular death, stroke, myocardial infraction, MACE, and amputation was found when DOACs were compared to antiplatelet monotherapy. The benefits of preventing target lesion revascularization and acute limb ischemia were balanced by amplified risk of major bleeding. Larger randomized controlled trials are needed to figure out the uncertainty around efficacy and safety of medications for peripheral arterial disease.

Abstract
Пациенты с заболеваниями периферических артерий (ЗПА), перенесшие открытые реконструктивные или эндоваскулярные вмешательства, входят в группу повышенного риска ишемических осложнений. В то время как очевидные преимущества интенсификации антитромботической терапии были продемонстрированы после реваскуляризации коронарных артерий при ишемической болезни сердца, указанный подход до недавнего времени не находил достаточных подтверждений у пациентов с ЗПА. Однако результаты исследований ATLAS ACS-TIMI 51 и COMPASS доказали целесообразность применения новой антитромботической стратегии – добавление «сосудистой» дозы ривароксабана к стандартной антитромбоцитарной терапии, что позволило снизить риск ишемических осложнений у пациентов, перенесших острый коронарный синдром, а также в случаях стабильного течения атеросклеротической болезни, в том числе ЗПА. Вместе с тем неизученным оставался вопрос относительно преимуществ такой терапии в популяции пациентов с ЗПА, которые перенесли открытую или эндоваскулярную реваскуляризацию нижних конечностей. В настоящей статье отражены ключевые положения исследования VOYAGER PAD, касающиеся высокой эффективности и приемлемой безопасности ривароксабана в сочетании с аспирином после периферических артериальных реконструктивных вмешательств.
Patients with peripheral artery disease (PAD), who underwent lower extremity revascularization, are at high risk of ischemic events. While intensification of antithrombotic therapy after revascularization has demonstrated the benefit in coronary disease population, this approach has not been well- studied or proven in PAD. Recent ATLAS ACS-TIMI 51 and COMPASS trials proved that the treatment strategy of rivaroxaban added to the background antiplatelet therapy reduced ischemic risk in patients, who had acute coronary syndromes, as well as in patients with stable atherosclerotic vascular disease, including PAD. Whether these benefits extend to the population of patients with symptomatic lower extremity PAD, who undergo revascularization, was the objective of the VOYAGER PAD trial. The final results of the VOYAGER PAD study revealed the effectiveness and acceptable safety of combined antithrombotic therapy after revascularization of peripheral arteries.

Abstract
BACKGROUND Clopidogrel monotherapy is guideline-recommended in symptomatic peripheral artery disease (PAD). The advent of new antithrombotic strategies prompts an updated analysis of available evidence on antiplatelet therapy for PAD. METHODS We searched MEDLINE, Embase and CENTRAL through January 2019 for randomised controlled trials and observational studies comparing antiplatelet therapies as monotherapy, dual therapy, or combination with anticoagulants. Efficacy (major adverse cardiovascular events, acute or chronic limb ischaemia, vascular amputation, peripheral revascularisation) and safety (all-cause mortality and overall bleeding) outcomes were evaluated via Bayesian network meta-analyses. RESULTS We analysed 26 randomised controlled trials. Clopidogrel (hazard ratio, HR, 0.78; 95% credible interval [CrI] 0.65-0.93) and ticagrelor (HR 0.80; 95% CrI 0.65-0.98) significantly reduced major adverse cardiovascular events risk compared with aspirin. No significant difference was observed for dual antiplatelet therapy with clopidogrel and aspirin. Vorapaxar significantly reduced limb ischaemia and revascularisation compared with placebo, while dual antiplatelet therapy with clopidogrel and aspirin showed a trend for reduced risk of amputation compared with aspirin (risk ratio 0.68; 95% CrI 0.43-1.04). For all-cause mortality, picotamide, vorapaxar, dipyridamole with aspirin, and ticlopidine showed a significantly lower risk of all-cause mortality vs aspirin. Clopidogrel and ticagrelor showed similar overall bleeding risk vs aspirin, while dual antiplatelet therapy with clopidogrel and aspirin significantly increased bleeding risk. CONCLUSION This updated network meta-analysis confirms that clopidogrel significantly decreases the risk of major adverse cardiovascular events compared with aspirin, without increasing bleeding risk. Clopidogrel should remain a mainstay of PAD treatment, at least in patients at higher bleeding risk.

Abstract
Background:
The VOYAGER PAD trial (Vascular Outcomes Study of ASA Along With Rivaroxaban in Endovascular or Surgical Limb Revascularization for Peripheral Artery Disease) demonstrated superiority of rivaroxaban plus aspirin versus aspirin to reduce major cardiac and ischemic limb events after lower extremity revascularization. Clopidogrel is commonly used as a short-term adjunct to aspirin after endovascular revascularization. Whether clopidogrel modifies the efficacy and safety of rivaroxaban has not been described.
Methods:
VOYAGER PAD was a phase 3, international, double-blind, placebo-controlled trial in patients with symptomatic PAD undergoing lower extremity revascularization randomized to rivaroxaban 2.5 mg twice daily plus 100 mg aspirin daily or rivaroxaban placebo plus aspirin. The primary efficacy outcome was a composite of acute limb ischemia, major amputation of a vascular cause, myocardial infarction, ischemic stroke, or cardiovascular death. The principal safety end point was TIMI (Thrombolysis in Myocardial Infarction) major bleeding, with International Society on Thrombosis and Haemostasis major bleeding a secondary safety outcome. Clopidogrel use was allowed at the discretion of the investigator for up to 6 months after the qualifying revascularization.
Results:
Of the randomized patients, 3313 (50.6%) received clopidogrel for a median duration of 29.0 days. Over 3 years, the hazard ratio for the primary outcome of rivaroxaban versus placebo was 0.85 (95% CI, 0.71–1.01) with clopidogrel and 0.86 (95% CI, 0.73–1.01) without clopidogrel without statistical heterogeneity (
P
for interaction=0.92). Rivaroxaban resulted in an early apparent reduction in acute limb ischemia within 30 days (hazard ratio, 0.45 [95% CI, 0.14–1.46] with clopidogrel; hazard ratio, 0.48 [95% CI, 0.22–1.01] without clopidogrel;
P
for interaction=0.93). Compared with aspirin, rivaroxaban increased TIMI major bleeding similarly regardless of clopidogrel use (
P
for interaction=0.71). With clopidogrel use >30 days, rivaroxaban was associated with more International Society on Thrombosis and Haemostasis major bleeding within 365 days (hazard ratio, 3.20 [95% CI, 1.44–7.13]) compared with shorter durations of clopidogrel (
P
for trend=0.06).
Conclusions:
In the VOYAGER PAD trial, rivaroxaban plus aspirin reduced the risk of adverse cardiovascular and limb events with an early benefit for acute limb ischemia regardless of clopidogrel use. The safety of rivaroxaban was consistent regardless of clopidogrel use but with a trend for more International Society on Thrombosis and Haemostasis major bleeding with clopidogrel use >30 days than with a shorter duration. These data support the addition of rivaroxaban to aspirin after lower extremity revascularization regardless of concomitant clopidogrel, with a short course (≤30 days) associated with less bleeding.
