BACKGROUND: Non-Hispanic Black and Hispanic patients with symptomatic PAD may receive different treatments than White patients with symptomatic PAD. The delivery of guideline-directed medical treatment may be a modifiable upstream driver of race and ethnicity-related disparities in outcomes such as limb amputation. The purpose of our study was to investigate the prescription of preoperative antiplatelets and statins in producing disparities in the risk of amputation following revascularization for symptomatic peripheral artery disease (PAD)...

BACKGROUND: Controversy regarding the definition of the upper limit of normal (ULN) for dilated mid-ascending aorta (mAA) stems from variation in criteria, based on several small-sized studies with small datasets of normal subjects (DONS). The present study was carried out to demonstrate this variation in the prevalence of mAA dilation and to identify the optimal definition by creating the largest DONS. METHODS: Echocardiographic studies of patients ≥ 15 years of age performed at a large tertiary care center over 4 years ( n = 49,330) were retrospectively evaluated...

INTRODUCTION: Functional performance is impaired in patients with peripheral artery disease (PAD). The effects of a supervised exercise training (SET) program on functional performance have yet to be clearly determined. The aim was to investigate the time-course evolution of functional performance during a 3-month SET program. METHODS: Patients with chronic symptomatic PAD participating in a 3-month SET program were investigated. Six-minute walking distance (6MWD), the stair climbing test (SCT), and the Short Physical Performance Battery (SPPB) were assessed before SET, after the first and second months of SET, and following the SET program...

INTRODUCTION: This study investigated disparities in health care access for Hispanic adults with diabetes and peripheral artery disease (PAD) who are at risk of lower-extremity amputation and other cardiovascular morbidities and mortalities. METHODS: We utilized the health care access survey data from the All of US research program to examine adults (⩾ 18 years) with either diabetes and/or PAD. The primary associations evaluated were: could not afford medical care and delayed getting medical care in the past 12 months...

BACKGROUND: Shared medical decision making requires patients' understanding of their disease and its treatment options. Peripheral artery disease (PAD) is a condition for which preference-sensitive treatments are available, but for which little is known about patients' knowledge and treatment preferences as it relates to specific treatment goals. METHODS: In a prospective, multicenter registry that involved patients with PAD experiencing claudication, the PORTRAIT Knowledge and Preferences Survey was administered at 1 year...

BACKGROUND: Persons living with human immunodeficiency virus (HIV, PLWH) have an increased risk of peripheral artery disease (PAD) in comparison to the general population. However, a gap remains in understanding optimal management for this condition. This study assesses longitudinal outcomes associated with peripheral endovascular intervention (PVI) for PAD among PLWH. METHODS: All Medicare fee-for-service patients undergoing femoropopliteal artery PVI between April 1, 2015 and December 31, 2018 were identified and stratified by HIV serostatus...

BACKGROUND: Medial arterial calcification (MAC) is a vascular disease distinct from atherosclerosis. Recently, several studies have demonstrated that MAC is an important marker of cardiovascular events. We aim to assess the presence of MAC during ultrasound screening of lower-limb vasculature and its association with both cardiovascular (CV) and lower-limb events in patients with type-2 diabetes. METHODS: A retrospective cohort study was conducted on 1119 patients with type-2 diabetes free from CV disease...

BACKGROUND: Underweight patients may be at an increased risk of bleeding while receiving venous thromboembolism (VTE) prophylaxis. Additional evidence is needed to identify patient-specific factors associated with bleeding. The objective of the study was to describe the incidence and identify risk factors associated with bleeding in low-weight (⩽ 60 kg) adult patients receiving subcutaneous unfractionated heparin (SQH) for VTE prophylaxis. METHODS: This was a single-center, retrospective, nested case-control study of low-weight patients receiving SQH for VTE prophylaxis for ⩾ 48 hours...

INTRODUCTION: Although favorable results of fluoropolymer-based drug-eluting stent (FP-DES) treatment for femoropopliteal lesions have been reported, it is unclear whether minimal lumen area (MLA) after FP-DES implantation affects clinical outcomes. This study aimed to reveal the association between intravascular ultrasound (IVUS)-evaluated MLA and the 1-year risk of restenosis and aneurysmal degeneration after FP-DES implantation for femoropopliteal lesions. METHODS: A subanalysis of the CAPSICUM (Contemporary outcomes After Paclitaxel-eluting peripheral Stent implantation for symptomatic lower limb IsChemia with sUperficial feMoral or proximal popliteal lesion) study analyzed 718 limbs in 686 patients with available IVUS-evaluated MLA data...

BACKGROUND: We sought to assess the safety and efficacy of endovenous thermal ablation (EVTA) in treating large great saphenous veins (GSV) > 12 mm in diameter. METHODS: We performed a systematic review according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) 2020 for comparative and noncomparative studies depicting EVTA in the treatment of GSV > 12 mm. Primary endpoints included GSV occlusion, technical success, deep vein thrombosis (DVT), and endovenous heat-induced thrombosis (EHIT)...
