Abstract:
Peripheral artery disease (PAD) is a manifestation of systemic atherosclerosis. Modifiable risk factors including cigarette smoking, dyslipidemia, diabetes, poor diet quality, obesity, and physical inactivity, along with underlying genetic factors contribute to lower extremity atherosclerosis. Patients with PAD often have coexistent coronary or cerebrovascular disease, and increased likelihood of major adverse cardiovascular events, including myocardial infarction, stroke and cardiovascular death. Patients with PAD often have reduced walking capacity and are at risk of acute and chronic critical limb ischemia leading to major adverse limb events, such as peripheral revascularization or amputation. The presence of polyvascular disease identifies the highest risk patient group for major adverse cardiovascular events, and patients with prior critical limb ischemia, prior lower extremity revascularization, or amputation have a heightened risk of major adverse limb events. Medical therapies have demonstrated efficacy in reducing the risk of major adverse cardiovascular events and major adverse limb events, and improving function in patients with PAD by modulating key disease determining pathways including inflammation, vascular dysfunction, and metabolic disturbances. Treatment with guideline-recommended therapies, including smoking cessation, lipid lowering drugs, optimal glucose control, and antithrombotic medications lowers the incidence of major adverse cardiovascular events and major adverse limb events. Exercise training and cilostazol improve walking capacity. The heterogeneity of risk profile in patients with PAD supports a personalized approach, with consideration of treatment intensification in those at high risk of adverse events. This review highlights the medical therapies currently available to improve outcomes in patients with PAD.

Abstract:
The purpose of our study was to determine outcome differences as a function of baseline high-sensitivity C-reactive protein (hsCRP) and B-type natriuretic peptide (BNP) levels in patients receiving lower extremity open reconstructions for the treatment of peripheral arterial occlusive disease. We retrospectively examined patients who underwent surgical reconstructions performed by a single operator during a seven-year time span who received preoperative hsCRP and BNP testing and post-procedure imaging. Outcomes of interest included major adverse limb events, a composite end point of target vessel revascularization, limb amputation, and disease progression, and major adverse cardiovascular events comprised of stroke, myocardial infarction, and death. A total of 89 limbs in 82 patients were included in analysis. Multivariate analysis demonstrated that higher hsCRP levels (>3.0 mg/L) trended toward, but failed to significantly associate with major adverse limb events at 24 months (hazard ratio: 2.2 [1.0–5.2], p = 0.06), however the use of a vein bypass conduit (vs. prosthetic reconstruction) significantly predicted major adverse limb events (hazard ratio: 3.2 [1.5–6.9], p < 0.01). Elevated BNP levels (>100 pg/ml), but not hsCRP, associated with major adverse cardiovascular events (hazard ratio: 3.5 [1.2–10.3], p = 0.03). Preoperative biochemical markers may assist in clinical decision making and stratifying patients regarding adverse events following open reconstructions.

Abstract:
ImportanceHigh lipoprotein(a) (Lp[a]) levels are involved in the development of cardiovascular events, particularly in myocardial infarction, stroke, and peripheral artery disease. Studies assessing the Lp(a) levels associated with adverse lower-limb events are lacking.ObjectiveTo assess the association between Lp(a) levels and incidence of major adverse limb events in unselected hospitalized patients.Design, Setting, and ParticipantsThis large retrospective monocentric cohort study was conducted from January 1, 2000, to December 31, 2020. Data were derived from the clinical information system of the Hôpital Européen Georges-Pompidou, a Paris-based university hospital. Patients who underwent at least 1 Lp(a) measurement at the center during the study period were included. Patients who had no follow-up data or who had the first Lp(a) measurement after the study outcome had occurred were excluded. Data analyses were performed from May 2021 to January 2022.Main Outcomes and MeasuresThe primary outcome was the first inpatient major adverse limb event, defined as a major amputation, peripheral endovascular revascularization, or peripheral surgical revascularization, during follow-up. Secondary outcomes included individual components of the primary outcome. Lipoprotein(a) levels were categorized as follows: normal (<50 mg/dL), high (50 to <134 mg/dL), and very high (≥134 mg/dL); to convert Lp(a) values to milligrams per liter, multiply by 0.1.ResultsA total of 16 513 patients (median [IQR] age, 58.2 [49.0-66.7] years; 9774 men [59.2%]) were included in the cohort. The median (IQR) Lp(a) level was 24 (10.0-60.0) mg/dL. The 1-year incidence of major adverse limb event was 2.44% in the overall population and 4.54% among patients with very high Lp(a) levels. High (adjusted accelerated failure time [AFT] exponential estimate: 0.43; 95% CI, 0.24-0.78; Benjamini-Hochberg–corrected P = .01) and very high (adjusted AFT exponential estimate: 0.17; 95% CI, 0.07-0.40; Benjamini-Hochberg–corrected P < .001) Lp(a) levels were independently associated with an increased risk of major adverse limb event.Conclusions and RelevanceResults of this study showed that higher Lp(a) levels were independently associated with an increased risk of a major adverse limb event in hospitalized patients. The Lp(a) measurement needs to be taken into account to improve lower-limb vascular risk assessment.

Abstract:
Objective: Cadaveric saphenous vein (CV) conduits are used in rare instances for limb salvage in patients without autogenous veins although long-term outcome data are scarce. This study was designed to evaluate the outcomes of CV bypass in patients with threatened limbs. Methods: We retrospectively reviewed the charts from 2010 to 2017 of 25 patients who underwent 30 CV allografts for critical limb ischemia and acute limb ischemia. Patient charts were reviewed for demographics, comorbidities, smoking status, indications for bypass, and outcomes. Primary outcomes included graft patency, major amputation rates, and mortality. Secondary outcomes measured included infection rates, 30-day major adverse cardiac events (MACE) and major adverse limb events (MALE). Statistical analysis was performed using time series and Kaplan-Meier survival curves. Results: A total of 30 limbs received CV lower extremity bypasses (20 males, 10 female), and the average age was 68 ± 4 years. Primary patency rates were 71%, 42%, and 28% at 3, 6, and 12 months, respectively. Assisted primary patency rates were 78%, 56%, and 37% at 3, 6, and 12 months, respectively. Secondary patency rates were 77%, 59%, and 28% at 3, 6, and 12 months, respectively. Minor amputations, defined as amputations below the transmetatarsal level occurred in 5 (20%) patients. Wound infection occurred in 8 (32%) patients which was managed with local wound care and no patients required an extraanatomic bypass for limb salvage. Thirty-day MALE occurred in 7 (23.3%) patients. We had no 30-day mortality or MACE. The average graft length was 64.2 ± 8 cm with an average graft diameter of 3.9 ± 2 mm. Amputation-free survival and overall survival at 12 months were 20 (68%) and 21 (84%), respectively. Conclusions: Cadaveric saphenous vein allograft may be used as a bypass conduit as a viable surgical option before limb amputation. Despite the poor patency rates, the limb salvage rates of cadaveric vein grafts demonstrate that this alternate conduit may be considered when no autogenous vein is available.

Abstract:
Objective: The aim of the present study was to investigate the possible relationship between the segmental burden of lower limb atherosclerosis and Major Adverse Cardiovascular Events (MACEs). Methods: All the consecutive symptomatic peripheral artery disease (PAD) patients admitted for digital subtraction angiography (DSA) at Turku University Hospital department of Vascular Surgery between 1 January 2009 and 30 July 2011 were retrospectively analyzed. Angiography due to symptomatic PAD was used as the index date for the inclusion in the study. The segmental burden of atherosclerosis based on DSA was divided into three categories according to the highest disease burden of the defined artery segment: aorto-iliac, femoropopliteal, or tibial segments. The major association for the study was MACEs (defined as a cerebrovascular event, heart failure (HF) and myocardial infarction requiring hospital admission). Demographic data and MACEs were obtained from the hospital electronic medical records system. Results. The lower limb atherosclerosis burden of tibial vessels was related to an increased probability for HF (OR 3.9; 95%CI 2.4–6.5) and for MACEs overall (OR 2.3; 95%CI 1.4–3.6). The probability of both HF and MACEs overall rose with the increasing severity of the atherosclerosis burden. Moreover, the more severe the tibial vessel atherosclerosis, the higher the risk of HF and MACEs. The most extensive tibial atherosclerosis patients had an OR 4.5; 95%CI 2.6–8.0 for HF and an OR 3.1; and 95%CI 1.7–5.6 for MACEs overall. The femoropopliteal disease burden was also associated with an increased risk of HF (OR 2.3; 95%CI 1.6–3.2) and MACE (OR 1.9; 95%CI 1.3–2.7). However, the increasing extent of atherosclerosis of the femoropopliteal segment solely increased the risk of MACEs. Conclusions: PAD patients with severe tibial atherosclerosis are likely to present with MACEs. The risk is further enhanced as the extent of tibial vessel atherosclerosis is increased. An association between MACE and severe atherosclerosis on the aortoiliac segment was not detected. However, when the femoropopliteal segment was the most affected artery segment, the risk of MACEs was increased.

Abstract:
Lower-extremity arterial disease (LEAD) is a major endemic disease with an alarming increased prevalence worldwide. It is a common and severe condition with excess risk of major cardiovascular events and death. It also leads to a high rate of lower-limb adverse events and non-traumatic amputation. The American Diabetes Association recommends a widespread medical history and clinical examination to screen for LEAD. The ankle brachial index (ABI) is the first non-invasive tool recommended to diagnose LEAD although its variable performance in patients with diabetes. The performance of ABI is particularly affected by the presence of peripheral neuropathy, medial arterial calcification, and incompressible arteries. There is no strong evidence today to support an alternative test for LEAD diagnosis in these conditions. The management of LEAD requires a strict control of cardiovascular risk factors including diabetes, hypertension, and dyslipidaemia. The benefit of intensive versus standard glucose control on the risk of LEAD has not been clearly established. Antihypertensive, lipid-lowering, and antiplatelet agents are obviously worthful to reduce major cardiovascular adverse events, but few randomised controlled trials (RCTs) have evaluated the benefits of these treatments in terms of LEAD and its related adverse events. Smoking cessation, physical activity, supervised walking rehabilitation and healthy diet are also crucial in LEAD management. Several advances have been achieved in endovascular and surgical revascularization procedures, with obvious improvement in LEAD management. The revascularization strategy should take into account several factors including anatomical localizations of lesions, medical history of each patient and operator experience. Further studies, especially RCTs, are needed to evaluate the interest of different therapeutic strategies on the occurrence and progression of LEAD and its related adverse events in patients with diabetes.
