This retrospective study determined the duplex ultrasound scanning criteria for detecting 50%-69% and 70%-99% stenosis of the superficial femoral artery (SFA). Examinations of 278 limbs in 185 patients with peripheral arterial disease were performed. Duplex ultrasound scanning was used to measure the diameter of the vascular lumen, the peak systolic velocity (PSV) at the stenotic segment of the SFA (PSVst), the segment proximal to the stenosis (PSVpro) and the popliteal artery (PSVpop, distal to the stenosis)...

Peripheral arterial disease (PAD) affects 15% of the Australian population and is a powerful and serious predictor of cardiovascular mortality yet continues to be under-recognised and undertreated. Diagnosis is simple and management is centred upon symptom relief and risk minimisation. While novel and specialised therapies play a role, the bulk of management is approachable and feasible. In this review, we cover the epidemiology, risk factors, associated conditions, classification, and natural history of PAD...

Cardiovascular disease (CVD) is frequent after kidney transplantation (KT). This study investigated CVD prediction in KT by information available before KT or within 6 months after KT. The study cohort consisted of 629 patients with KT in 2005-10 and with adult age at KT. The end point was incidence up to 2015 of CVD (coronary heart disease, cerebrovascular disease, peripheral artery disease). Graft failure, non-CVD death with functioning graft, and loss to follow-up were considered competing events. CVD prediction was investigated for 34 variables by means of competing-risks regression...

The diagnosis, surveillance, and management of infrapopliteal critical limb ischemia remain inconsistent among clinicians. This study demonstrates that using an absolute ankle pressure of >73 mm Hg or an absolute toe pressure increase of 1 mm Hg or greater post endovascular intervention in patients with infrapopliteal critical limb ischemia may be predictive of a reduction in target limb revascularization, amputation, and death. This study highlights the need for vascular societies to come together to promote standardized screening, surveillance, and treatment paradigms for this complex population...

OBJECTIVES: The endocannabinoid (eCB) system centrally and peripherally regulates cardiovascular parameters, including blood pressure, in health and disease. The relationship between Gq/11 protein-coupled receptor activation, regulation of eCBs release (mainly 2-arachidonoylglycerol) and subsequent CB1 receptor activation was initially observed in the central nervous system. Here, we review the latest findings from systemic physiological studies which include for the first time data from pulmonary arteries...

BACKGROUND: Coronary slow flow (CSF), an angiographic phenomenon that is characterized by a delayed coronary blood flow in the absence of obstructive coronary artery stenosis, is known as a disorder of the coronary microcirculation. Inflammation has an important role in the vascular hemostasis and endothelial dysfunction especially regarding monocyte adhesion and infiltration. Pro-inflammatory cytokines released by inflammatory cells result in endothelial cell dysfunction and cardiovascular diseases...

BACKGROUND: Supervised walking is a first line therapy in peripheral arterial disease (PAD) with complaints of intermittent claudication. However, uptake of supervised programmes is low. Home-based exercise seems an appealing alternative; especially since technological advances, such as tele-coaching and tele-monitoring, may facilitate the process and support patients when adopting a physically active lifestyle. To guide the development of such an intervention, it is important to identify barriers of physical activity and the needs and interests for technology-enabled exercise in this patient group...

The current European Society of Cardiology (ESC) guidelines on peripheral arterial diseases include recommendations on diagnostics and treatment of atherosclerotic manifestations in peripheral arteries. Because of the high coincidence of atherosclerosis in different arterial territories, screening for other atherosclerotic lesions is necessary in patients with clinical symptoms in one vascular bed. Consistent treatment of cardiovascular risk factors is important in all patients with peripheral atherosclerosis...

Importance: Benefits of granulocyte-macrophage colony-stimulating factor (GM-CSF) for improving walking ability in people with lower extremity peripheral artery disease (PAD) are unclear. Walking exercise may augment the effects of GM-CSF in PAD, since exercise-induced ischemia enhances progenitor cell release and may promote progenitor cell homing to ischemic calf muscle. Objectives: To determine whether GM-CSF combined with supervised treadmill exercise improves 6-minute walk distance, compared with exercise alone and compared with GM-CSF alone; to determine whether GM-CSF alone improves 6-minute walk more than placebo and whether exercise improves 6-minute walk more than an attention control intervention...

A 81-year-old man was admitted to our university for a second opinion after diagnosis of bladder melanoma in December 2014. His medical history included arterial hypertension, hypothyroidism, peripheral arterial disease treated with a bypass, and corneal transplantation. His medical history was negative for malignant melanoma. He experienced gross hematuria in the absence of any other clinical manifestations, and urine cytology identified atypical cells. The patient underwent transurethral resection of the bladder with diagnosis of melanoma...

OBJECTIVE: The numbers of lower extremity revascularisations and amputations are insufficiently reported in Norway. To support future policy decisions regarding the provision of vascular treatment, knowledge of such trends is important. METHODS: This retrospective cross-sectional study from 2001 to 2014 used data from the Norwegian Patient Registry. The revascularisation treatments were categorised in multilevel, aortoiliac, femoral to popliteal and popliteal to foot levels and sorted as open, endovascular and hybrid...

Peripheral artery disease (PAD) is one of the most common cardiovascular complications in patients with type 2 diabetes mellitus (T2DM)(1) and is a predictor of cardiovascular death.(2) Interventions that reduce cardiovascular complications in this patient population are urgently required. In the EMPA-REG OUTCOME trial, the sodium glucose cotransporter 2 inhibitor empagliflozin reduced the risk of cardiovascular death by 38% (hazard ratio [HR], 0.62; 95% confidence interval [CI] 0.49-0.77]) and hospitalization for heart failure (HHF) by 35% (HR, 0...

BACKGROUND: Patients with peripheral artery disease have an increased risk of cardiovascular morbidity and mortality. Antiplatelet agents are widely used to reduce these complications. METHODS: This was a multicentre, double-blind, randomised placebo-controlled trial for which patients were recruited at 602 hospitals, clinics, or community practices from 33 countries across six continents. Eligible patients had a history of peripheral artery disease of the lower extremities (previous peripheral bypass surgery or angioplasty, limb or foot amputation, intermittent claudication with objective evidence of peripheral artery disease), of the carotid arteries (previous carotid artery revascularisation or asymptomatic carotid artery stenosis of at least 50%), or coronary artery disease with an ankle-brachial index of less than 0·90...
