Urinary vanin-1 as a novel biomarker for survival in peripheral artery disease.

Background: Chronic kidney disease is associated with increased rates of incidence, morbidity, and mortality in lower-extremity peripheral artery disease (PAD). No specific marker for a functional risk assessment of kidney disease in PAD is known, especially at the early stages. Thus, we speculated that urinary vanin-1 (uVNN1), a marker of oxidative stress even in early kidney injury, could further stratify outcome assessment in patients with PAD.

A RAND/UCLA-Modified VAS Study on Telemedicine, Telehealth, and Virtual Care in Daily Clinical Practice of Vascular Medicine.

Telemedicine is increasingly used in several fields of healthcare, including vascular medicine. This study aimed to investigate the views of experts and propose clinical practice recommendations on the possible applications of telemedicine in vascular medicine. A clinical guidance group proposed a set of 67 clinical practice recommendations based on the synthesis of current evidence and expert opinion.

Serum Trefoil Factor-3 Predicts Survival in Peripheral Artery Disease.

Trefoil factor 3 (TFF3) has been studied in processes leading to atherosclerosis. Data are scarce in manifest disease and missing in peripheral artery disease (PAD). This study aims to elucidate TFF3 with disease stages, degrees of atherosclerosis, and outcomes.

Hyperparathyroidism and Peripheral Arterial Disease.

Primary hyperparathyroidism (PHPT) is presented in various forms, including classic PHPT, characterised by increased parathyroid hormone (PTH) secretion, normohormonal PHPT, and normocalcaemic PHPT. Secondary hyperparathyroidism is characterised by increased PTH secretion triggered by factors such as vitamin D deficiency and kidney failure. This review aims to discuss the involvement of hyperparathyroidism (HPT) in atherosclerosis, including peripheral arterial disease (PAD).

Thyroid Disorders and Peripheral Arterial Disease.

Hypothyroidism and hyperthyroidism, both overt and subclinical, are associated with increased risk of cardiovascular morbidity and mortality. The association between thyroid-stimulating hormone levels and cardiovascular risk has been demonstrated in large epidemiological studies and meta-analyses and is now considered a U-shaped curve. Several pathophysiological mechanisms linking thyroid and cardiovascular disease are known; however, specific clinical complications of peripheral arterial disease as endpoints of clinical trials have not been adequately investigated.

Cardiometabolic Risk, Peripheral Arterial Disease and Cardiovascular Events in Polycystic Ovary Syndrome: Time to Implement Systematic Screening and Update the Management.

Polycystic ovary syndrome (PCOS) is a highly prevalent endocrine disorder in women of reproductive age. It presents with gynaecologic, metabolic, and psychologic manifestations. The dominant drivers of pathophysiology are hyperandrogenism and insulin resistance.

The Effect of Menopause and Menopausal Hormone Therapy on the Risk of Peripheral Artery Disease.

Peripheral artery disease (PAD), defined as lower extremity arterial disease, constitutes an underestimated aspect of the menopause-associated risk of atherosclerotic cardiovascular disease (ASCVD). Accumulation of ASCVD risk factors, such as atherogenic dyslipidaemia, diabetes, and arterial hypertension, after the transition to menopause may contribute to atherosclerotic plaque formation in peripheral arteries. However, inconsistency exists among studies as to whether transition to menopause increases the risk of PAD, although early menopause (<45 years) or premature ovarian insufficiency may accelerate peripheral atherosclerotic plaque formation.

Involvement of APOE in Incidence of Revascularization in Patients Affected by Peripheral Arterial Disease: A Prospective Study from Southern Italy.

Introduction: Atherosclerosis is a complex multifactorial disease and apolipoprotein E (APOE) polymorphism has been associated with cardiovascular events. The APOE gene, located on chromosome 19q13.2, has an important role in lipid metabolism, in particular on circulating cholesterol levels, implying further pleiotropic effects; from its polymorphism are derived three alleles (ε2, ε3 and ε4), which induce different phenotypes, while its impact on carotid and femoral atherosclerosis is still controversial.

Testosterone and Peripheral Arterial Disease.

Testosterone levels in men begin declining in the early years of adulthood, with a 1-2% reduction/year. Low testosterone levels in men are associated with obesity, metabolic syndrome, diabetes mellitus, dyslipidaemia, hypertension and increased cardiovascular mortality. However, observational studies of testosterone levels in males and their relationship with peripheral arterial disease (PAD) have yielded mixed results; only some cohorts show a clear association with low free testosterone levels.

NT-proBNP as a surrogate for unknown heart failure and its predictive power for peripheral artery disease outcome and phenotype.

Patients with peripheral artery disease (PAD) are at high risk of excess mortality despite major improvements in multimodal pharmacotherapy for cardiovascular disease. However, little is known about co-prevalences and implications for the combination of heart failure (HF) and PAD. Thus, NT-proBNP as a suggested surrogate for HF was evaluated in symptomatic PAD regarding long-term mortality.

The importance of socio-economic determinants of health in the care of patients with peripheral artery disease: A narrative review from VAS.

Socio-economic determinants of health (SDoH) include various nonmedical factors in the socio-economic sphere with a potentially significant impact on health outcomes. Their effects manifest through several mediators/moderators (behavioral characteristics, physical environment, psychosocial circumstances, access to care, and biological factors). Various critical covariates (age, gender/sex, race/ethnicity, culture/acculturation, and disability status) also interact.

[Individualising antihypertensive therapy in patients with diabetes. A guideline by the Austrian Diabetes Association (update 2023)].

Hypertension is one of the most important comorbidities of diabetes, contributing significantly to death and leading to macrovascular and microvascular complications. When assessing the medical priorities for patients with diabetes, treating hypertension should be a primary consideration. In the present review practical approaches to hypertension in diabetes, including individualized targets for preventing specific complications are discussed according to current evidence and guidelines.

Secondary calciprotein particle size is associated with patient mortality in peripheral artery disease.

Background And Aims: Secondary calciprotein particles (CPP-II) induce inflammation and contribute to vascular calcification. CPP-II size is associated with vascular calcification in patients with chronic kidney disease (CKD) and all-cause mortality in hemodialysis patients. Here, we investigate for the first time a possible role of CPP-II size in patients with peripheral artery disease (PAD) without severe CKD.

Lipoprotein (a) and long-term outcome in patients with peripheral artery disease undergoing revascularization.

Background And Aims: Despite low LDL-C goals, the residual risk for further cardiovascular (CV) events in patients with peripheral artery disease (PAD) remains high. Lipoprotein (a) (Lp(a)) is a known risk factor for PAD incidence, but little is known regarding the outcome in patients with symptomatic PAD. Thus, this study investigates Lp(a) and CV mortality in PAD after endovascular repair.

High-Density Lipoprotein Particle Subclasses in Statin-Treated Patients with Peripheral Artery Disease Predict Long-Term Survival.

Low-density lipoprotein-cholesterol reduction showed a strong reduction of cardiovascular (CV) event rates in CV disease. However, the residual risk of future CV events remains high, which especially extends to peripheral arterial disease (PAD). Nuclear magnetic resonance (NMR) spectroscopy offers a novel method for analysis of the lipoprotein spectrum.

Galectin-3 is linked to peripheral artery disease severity, and urinary excretion is associated with long-term mortality.

Background And Aims: Galectin-3 (Gal-3) is a biomarker involved in fibrosis and vascular inflammation. Gal-3 has been linked to chronic kidney disease (CKD) and patients with peripheral artery disease (PAD). Conflicting reports exist about the relevance of Gal-3 in PAD.

Calcification Propensity in Serum and Cardiovascular Outcome in Peripheral Artery Disease.

Peripheral artery disease (PAD) has been shown to be linked to elevated cardiovascular risk. The novel T test quantifies calcification propensity of serum and has been associated with cardiovascular events and mortality in patients with chronic kidney disease (CKD) and in the general population. This study investigated the association of calcification propensity measured by the T test in 287 patients with PAD without severe CKD.
