Despite celiprolol therapy, patients with vascular Ehlers-Danlos syndrome remain at risk of vascular events: A 12-year experience in an Italian referral center.

BACKGROUND: Vascular Ehlers-Danlos syndrome (vEDS) is an inherited connective tissue disorder characterized by arterial fragility. Celiprolol has been suggested to significantly reduce rates of vascular events in this setting, though real-world evidence is limited. The aim of this study was to report our experience with celiprolol therapy in vEDS management. METHODS: Patients with a genetically confirmed diagnosis of vEDS who were referred for outpatient consultation at the Brescia University Hospital between January 2011 and July 2023 were included. At each visit, patients' medical history, results of vascular imaging, and office blood pressure measurements were recorded. Celiprolol therapy was progressively titrated to the maximum tolerated dose of up to 400 mg daily, according to the patients' tolerance. RESULTS: Overall, 26 patients were included. Female sex was prevalent (62%). Mean (SD) age was 37 (16) years. Follow-up duration was 72 (41) months. At the last follow-up visit, all patients were on celiprolol therapy, 80% of whom were taking the maximum recommended dose. The yearly risk of symptomatic vascular events was 8.8%, the majority of which occurred after reaching the maximum recommended dose of celiprolol. No significant predictor of symptomatic vascular events was identified among patients' clinical characteristics. CONCLUSION: In our cohort, rates of celiprolol use were high and the drug was well tolerated overall. Nonetheless, the risk of symptomatic vascular events remained nonnegligible. Future studies should identify reliable predictors of major adverse events and explore additional therapeutic strategies that could further lower the risk of life-threatening events in this population.

Adverse reactions after intravascular iodinated contrast media administration and their management.

Endovascular interventions and diagnostic examinations using iodinated contrast media (ICM) are standard of care in current vascular medicine. Although ICM use is generally considered safe, it may be associated with adverse reactions, vary from minor disturbances to rare, but severe life-threatening complications. This position paper of European Society of Vascular Medicine integrates current knowledge and summarizes the key information related to the use of intravascular ICM, serving as recommendation on prevention and management of acute, late, and very late adverse reactions. It should help the health professionals in all fields of vascular medicine to make decisions in daily practice for safe use of contrast media.

Pulmonary Embolism in Patients with COVID-19: Comparison between Different Care Settings.

The clinical characteristics and outcomes of patients with coronavirus disease 2019 (COVID-19) who develop pulmonary embolism (PE) in the full spectrum of patient care settings need to be elucidated. The aim of this study was to compare the clinical characteristics, treatment, and 90-day outcomes in patients diagnosed with PE while recovering from COVID-19 in the outpatient setting versus those who were diagnosed with PE while being hospitalized with COVID-19. Data from the international Registro Informatizado de Enfermedad TromboEmbólica (RIETE) registry were used. The major study outcomes were all-cause death, major bleeding, and venous thromboembolism (VTE) recurrences during the first 90 days after PE. From March 2020 to March 2021, 737 patients with COVID-19 experienced acute PE. Of these, 340 (46%) were recovering from COVID-19 as outpatients (267 patients who had been treated at home for COVID-19 and 73 discharged after being hospitalized with COVID-19). Compared with inpatients with COVID-19, those recovering in the outpatient setting upon PE were less likely to be men (odds ratio [OR]: 0.54; 95% confidence interval [CI]: 0.40-0.72) and less likely to have hypertension (OR: 0.55; 95% CI: 0.41-0.74) or diabetes (OR: 0.51; 95% CI: 0.33-0.76). At 90-day follow-up, eight patients (none recovering from COVID-19 as outpatient vs. 2.4% of inpatients with COVID-19) developed recurrent VTE, 34 (1.9 vs. 7.9%) had major bleeding, and 128 (10 vs. 24%) died. On multivariable analysis, inpatients with COVID-19 were at a higher risk of major bleeding (adjusted hazard ratio [HR]: 6.80; 95% CI: 1.52-30.4) or death (adjusted HR: 2.24; 95% CI: 1.40-3.58). In conclusion, using a large multinational registry of patients with COVID-19 who experienced PE, thromboembolic episodes occurring in those recovering from COVID-19 as outpatients were associated with less ominous outcomes than inpatients with COVID-19.

Less sodium and more potassium to reduce cardiovascular risk.

An increase in the dietary consumption of salt is associated with a progressive increase in blood pressure (BP) values, and with an increase in the incidence of cardiovascular disease. Reducing the dietary intake of sodium in the population is a public health goal in many countries around the world. Numerous studies have described a linear relationship between high dietary salt intake and the development of arterial hypertension, as well as a negative association between high potassium intake and BP values. Furthermore, there is evidence that a reduction in salt consumption and an increase in potassium consumption can be associated with a decrease in BP values, improving the general state of health. Therefore, it would be desirable to further improve awareness of the risks associated with an excessive intake of salt and low potassium by maintaining public education campaigns and trying to overcome the numerous obstacles to a process of greater responsibility for people regarding nutrition.

The Role of Neutrophils in Lower Limb Peripheral Artery Disease: State of the Art and Future Perspectives.

In recent years, increasing attention has been paid to the role of neutrophils in cardiovascular (CV) disease (CVD) with evidence supporting their role in the initiation, progression, and rupture of atherosclerotic plaque. Although these cells have long been considered as terminally differentiated cells with a relatively limited spectrum of action, recent research has revealed intriguing novel cellular functions, including neutrophil extracellular trap (NET) generation and inflammasome activation, which have been linked to several human diseases, including CVD. While most research to date has focused on the role of neutrophils in coronary artery and cerebrovascular diseases, much less information is available on lower limb peripheral artery disease (PAD). PAD is a widespread condition associated with great morbidity and mortality, though physician and patient awareness of the disease remains low. To date, several studies have produced some evidence on the role of certain biomarkers of neutrophil activation in this clinical setting. However, the etiopathogenetic role of neutrophils, and in particular of some of the newly discovered mechanisms, has yet to be fully elucidated. In the future, complementary assessment of neutrophil activity should improve CV risk stratification and provide personalized treatments to patients with PAD. This review aims to summarize the basic principles and recent advances in the understanding of neutrophil biology, current knowledge about the role of neutrophils in atherosclerosis, as well as available evidence on their role of PAD.

Indocyanine green lymphography as novel tool to assess lymphatics in patients with lipedema.

OBJECTIVE: Lipedema is a chronic and progressive disease associated with lymphatic impairment at later stages. The aim of our study was to describe the functional status and anatomy of lower limb superficial lymphatic system using indocyanine green (ICG) lymphography in patients with lipedema. METHODS: Following ICG injection at the dorsum of the foot, distance (cm) covered by the dye at 10 (T10') and 25 min (T25') was measured and normalized for limb length. If the dye did not reach the groin within 25 min, patients were classified as "drainage-needing" group (DNG). Values of fat and lean distribution assessed by dual-energy X-ray absorptiometry were extracted, and correlation analysis was performed. Furthermore, anatomical patterns of superficial lymphatics were assessed. RESULTS: Overall, 45 women were included, 25 (56%) of whom were classified as DNG. Symptoms duration was significantly associated with DNG status at multivariate analysis (odds ratio 1.07; 95% CI 1.01-1.14; p = 0.047). Moreover, Spearman's analysis showed a negative correlation between symptoms duration and T25' dye migration (r = -0.469; p = 0.037). Overall, no major anatomical lymphatic changes were found. CONCLUSIONS: Present study suggests that lymphatic functioning in patients with lipedema correlates with symptoms duration. Further research on larger cohorts should verify our findings and clarify their potential therapeutic implications. Overall, ICG lymphography may be promising technique to assess both lymphatic anatomy and functioning in patients with lipedema.

The effects of COVID-19 pandemic on patients with lower extremity peripheral arterial disease: A near miss disaster.

BACKGROUND: The COVID-19 pandemic has led to widespread postponement and cancelation of elective vascular surgeries in Switzerland. The consequences of these decisions are poorly understood. PATIENTS AND METHODS: In this observational, retrospective, single-center cohort study, we describe the impact of COVID-19 pandemic containment strategies on patients with lower extremity peripheral arterial disease (PAD) referred during the period March 11, to May 11, 2020, compared to the same time frames in 2018 to 2019. Patients admitted for acute limb ischemia (ALI) or chronic PAD and undergoing urgent or elective vascular surgery or primary amputation were included. Patients' characteristics, indications for admission, and surgical features were analyzed. The occurrence of 30 day outcomes was assessed, including length of stay, rates of major adverse cardiovascular events (MACE) and major adverse limb events (MALE), and procedural and hemodynamic success. RESULTS: Overall, 166 patients were included. Fewer subjects per 10 day period were operated in 2020 compared to, 2018 to 2019 (6.7 vs. 10.5, respectively; P < 0.001). The former had higher rates of chronic obstructive pulmonary disease (COPD) (25% vs. 11.1%; P = 0.029), and ASA score (3.13 vs. 2.90; P = 0.015). The percentage of patients with ALI in 2020 was about double that of the same period in 2018 to 2019 (47.5% vs. 24.6%; P = 0.006). Overall, the types of surgery were similar between 2020 and 2018 to 2019, while palliative care and primary amputations occurred only in 2020 (5 out 40 cases). The rate of post-operative MACE was significantly higher in 2020 (10% vs. 2.4%; P = 0.037). CONCLUSIONS: During the first state of emergency for COVID-19 pandemic in 2020, less regular medical follow-up and hindered hospital access could have resulted in more acute and advanced clinical presentations of patients with PAD undergoing surgery. Guidelines are needed to provide appropriate care to this vulnerable population and avoid a large-scale disaster.

[Subclinical atherosclerosis in hypercholesterolemia - Towards a personalized, shared decision-making cardiovascular prevention]. / Dépistage de l'athérosclérose dans l'hypercholestérolémie - Vers une prévention cardiovasculaire personnalisée et partagée.

Identification of subjects at increased cardiovascular risk (CV) using traditional risk calculators is established. Nevertheless, up to 50% of CV events occur in people classified as intermediate risk. Non-invasive atherosclerosis (ATS) assessment with carotid/femoral US and coronary artery calcium score, offers the opportunity of a personalized prevention. ATS detection could be useful in improving CV risk stratification, in optimizing individual therapeutic management and in promoting a shared decision-making process. Is this the era of a paradigm shift in CV-risk prediction? The fascinating question is still open, but the increasing number of evidences shed new insights for our everyday clinical practice. Here we strive to provide an updated scenario on the use of ATS imaging in the CV risk evaluation and therapeutic decision.

L'identification des sujets avec un risque cardiovasculaire (CV) élevé en utilisant les calculateurs de risque traditionnels est établie, cependant près de 50 % des événements CV surviennent chez des personnes à risque intermédiaire. Le dépistage de l'athérosclérose (ATS) par ultrason des artères carotides et fémorales et par le score calcique coronarien offre la possibilité d'une prévention personnalisée. La détection de l'ATS subclinique permettrait d'améliorer la stratification du risque CV, optimiser la prise en charge individuelle et la décision partagée. Est-ce l'ère d'un changement de la prédiction du risque CV ? La question est encore ouverte mais il y a des nouveautés concernant notre pratique clinique. Nous proposons un panorama actualisé du dépistage de l'ATS, son impact sur la stratification du risque CV et la décision thérapeutique.

[Screening for peripheral arterial disease : role of the primary care physician]. / Dépistage de l'artériopathie oblitérante des membres inférieurs : rôle du médecin de premier recours.

Peripheral arterial disease (PAD) is a widespread disease with high impact on global health. While general population screening is not currently indicated, the primary care physician has the critical role of identifying asymptomatic patients who are particularly at risk for PAD and could therefore benefit from screening. In addition, he or she must recognize the typical and atypical clinical presentations of patients with symptomatic PAD to ensure proper diagnosis and care. After an adequate medical history and clinical examination, the first diagnostic test is the « Ankle-Brachial Index ¼ (ABI) calculation. In case of pathologic ABI (≤ 0.9, or > 1.4), or in case of normal or borderline ABI with symptoms, the patient should be referred to a vascular medicine physician for diagnostic confirmation and management.

L'artériopathie oblitérante des membres inférieurs est une maladie très répandue ayant un impact remarquable sur la santé mondiale. Bien que le dépistage dans la population générale ne soit pas indiqué, le médecin de premier recours a le rôle essentiel d'identifier les patients asymptomatiques qui pourraient bénéficier du dépistage. En outre, il·elle doit reconnaître les présentations cliniques typiques et atypiques chez les patients symptomatiques, afin d'assurer le diagnostic. Après l'anamnèse et l'examen clinique, le premier test de dépistage est le calcul de l'index cheville-bras. En cas de valeurs pathologiques (≤ 0,9 ou > 1,4), normales ou « borderline ¼ en présence de symptômes, le patient doit être adressé à un angiologue pour confirmation du diagnostic et prise en charge.

[Vascular passport : a tool for secondary prevention among patients with peripheral artery disease]. / Passeport vasculaire : un outil pour la prévention secondaire des patients avec maladie artérielle périphérique.

Peripheral arterial disease (PAD) is a major health problem in Switzerland, as myocardial infarction or stroke, all three sharing common cardiovascular (CV) risk factors and similar pathophysiological mechanisms (atherosclerosis). Unfortunately, PAD is still often overlooked, despite being fraught with significant morbidity/mortality and increasing the patient's overall CV risk. It is therefore essential to improve secondary prevention in order to decrease this burden and the overall CV risk of the patient. We will review the treatment targets for CV risk factors as secondary prevention in patients with PAD and see how the use of a vascular passport may improve management.

La maladie artérielle périphérique (MAP) est une problématique de santé majeure en Suisse, au même titre que l'infarctus du myocarde ou l'AVC, tous les trois partageant des facteurs de risque cardiovasculaire (FRCV) communs et des mécanismes physiopathologiques similaires (athérosclérose). Malheureusement, l'importance de la MAP est encore souvent sous-estimée, alors qu'elle est grevée d'une morbidité et d'une mortalité importantes et augmente le risque cardiovasculaire (CV) global du patient. Il est capital d'améliorer la prévention secondaire afin de diminuer ce fardeau et le risque CV global du patient. Nous allons passer en revue les cibles de traitement des FRCV en prévention secondaire chez les patients avec MAP et voir comment l'utilisation d'un passeport vasculaire permet d'améliorer la prise en charge.

[Intima-media thickness and carotidofemoral plaques for cardiovascular risk stratification]. / Épaisseur intima-média et plaques carotido-fémorales pour stratifier le risque cardiovasculaire.

Cardiovascular (CV) diseases are still one of the most important -killers in developed countries. In the last 40 years, great progresses have been achieved in recognizing and treating these diseases and their underlying risk factors. Risk assessment models using tradi-tional risk factors estimate the probability of a cardiovascular event in most cases and drive preventive treatment. However, these risk assessment models have weaknesses, and it is estimated that about 30 % of cardiovascular events are related to undetected risks. Many surrogate parameters have been investigated and have the potential to better predict CV risk beyond classical risk factors. The aim of this article is to assess the value of measuring the intima-media thickness and the detection of atheroma of the carotid and femoral bifurcation by ultrasound.

Dans les pays industrialisés, les maladies cardiovasculaires (CV) sont toujours une cause majeure de mortalité. Au cours des 40 ­dernières années, d'importants progrès ont permis de mieux ­reconnaître et traiter ces maladies et leurs causes. Les scores utilisant des facteurs de risque permettent d'estimer la probabilité d'un événement CV et de gérer la prévention primaire. Cependant, environ 30 % des événements CV échappent aux modèles de prédiction, raison pour laquelle de nombreux paramètres ont été étudiés afin de mieux identifier le risque au-delà des facteurs de risque CV traditionnels. L'objectif de cet article est de décrire la valeur ajoutée de la mesure de l'épaisseur intima-média (EIM) et du dépistage de plaques des bifurcations carotido-fémorales par échographie.

[Should patients with type 2 diabetes be screened for lower extremity arterial disease?] / Faut-il dépister l'artériopathie oblitérante des membres inférieurs chez les patients avec diabète de type.

Lower extremity arterial disease (LEAD) is a serious and invalidating disease with a relatively high prevalence in the diabetic population. Patients suffering from both conditions have a less favourable prognosis of affected limbs compared to non-diabetic patients, with more frequent adverse limb events such as amputations. Nevertheless, awareness of LEAD remains sub-optimal in the diabetic population. Regular and appropriate screening for this condition is therefore recommended. Affected individuals should receive optimal medical treatment, including intensive management of the various cardiovascular risk factors and strict blood glucose control.

L'artériopathie oblitérante des membres inférieurs (AOMI) est une pathologie souvent sévère et invalidante, relativement fréquente dans la population diabétique. Les patients atteints des deux maladies ont un pronostic moins favorable au niveau des membres inférieurs par rapport aux patients non diabétiques, et souffrent plus fréquemment de complications graves comme des amputations. Néanmoins, la sensibilisation à l'AOMI chez les médecins prenant en charge les patients diabétiques reste sous-optimale. Un dépistage régulier et approprié de cette condition est donc recommandé. Les patients affectés doivent recevoir un traitement médical optimal, incluant une prise en charge intensive des différents facteurs de risque cardiovasculaire et un contrôle strict des glycémies.

[Best medical treatment of lower extremity arterial disease in 2018]. / Traitement médical optimal de l'artériopathie oblitérante des membres inférieurs en 2018.

Lower extremity artery disease is a very common disease, which is frequently associated with consistent disability in terms of both clinical symptoms and functioning. It is also associated with important morbidity and mortality, because of a significant increase in overall cardiovascular risk in affected patients. The establishment of an optimal medical treatment, including a careful management of the different cardiovascular risk factors through a healthy lifestyle, a regular and structured physical activity and the administration (if indicated) of antihypertensive, lipid-lowering, antidiabetic and antithrombotic drugs is a fundamental component in the clinical management of these patients and should always be considered by the clinicians facing the disease.

L'artériopathie oblitérante des membres inférieurs est une pathologie très fréquente, souvent invalidante autant sur le plan symptomatologique que fonctionnel. Elle est associée par ailleurs à une morbidité et une mortalité considérables, en raison d'une augmentation significative du risque cardiovasculaire global chez les patients atteints. L'instauration d'un traitement médical optimal, incluant une gestion attentive des différents facteurs de risque cardiovasculaire au travers d'un mode de vie sain, d'une activité physique régulière et structurée et de l'administration (si indiquée) de médicaments antihypertenseurs, hypolipémiants, antidiabétiques et antithrombotiques, représente le pilier du traitement des patients artériopathes et doit être encouragée et gérée par les médecins en charge de ces patients.

The Global Burden of Resistant Hypertension and Potential Treatment Options.

Resistant hypertension (RH) is defined as systolic blood pressure (SBP) or diastolic blood pressure (DBP) that remains .140 mmHg or .90 mmHg, respectively, despite an appropriate lifestyle and the use of optimal or maximally tolerated doses of a three-drug combination, including a diuretic. This definition encompasses the category of controlled RH, defined as the presence of blood pressure (BP) effectively controlled by four or more antihypertensive agents, as well as refractory hypertension, referred to as uncontrolled BP despite five or more drugs of different classes, including a diuretic. To confirm RH presence, various causes of pseudo-resistant hypertension (such as improper BP measurement techniques and poor medication adherence) and secondary hypertension must be ruled out. Inadequate BP control should be confirmed by out-of-office BP measurement. RH affects about 5% of the hypertensive population and is associated with increased cardiovascular morbidity and mortality. Once RH presence is confirmed, patient evaluation includes identification of contributing factors such as lifestyle issues or interfering drugs/substances and assessment of hypertension-mediated organ damage. Management of RH comprises lifestyle interventions and optimisation of current medication therapy. Additional drugs should be introduced sequentially if BP remains uncontrolled and renal denervation can be considered as an additional treatment option. However, achieving optimal BP control remains challenging in this setting. This review aims to provide an overview of RH, including its epidemiology, pathophysiology, diagnostic work-up, as well as the latest therapeutic developments.

Tortuosity in non-atherosclerotic vascular diseases is associated with age, arterial aneurysms, and hypertension.

BACKGROUND: Increased arterial tortuosity has been associated with various cardiovascular complications. However, the extent and role of arterial tortuosity in non-atherosclerotic vascular diseases remain to be fully elucidated. This study aimed to assess arterial tortuosity index (ATI) in patients with non-atherosclerotic vascular diseases and the associated factors. METHODS: This is a retrospective analysis of patients with non-atherosclerotic vascular diseases referred to the Malformation and Rare Vascular Disease Center at the University Hospital in Lausanne (Switzerland). Computed tomography angiography (CTA) images performed between October 2010 and April 2022 were retrieved and the aortic tortuosity index (ATI) was calculated. Patients were classified based on diagnosis into the following groups: arterial dissection & aneurysm, arteritis & autoimmune disease, hereditary connective tissue diseases, and fibromuscular dysplasia (FMD). Univariate and multivariate logistic regression analysis was used to determine potentially relevant predictors of aortic tortuosity. RESULTS: The mean age upon computed tomography angiography (CTA) was 46.8 (standard deviation [SD] 14.6) years and 59.1% of the patients were female. Mean ATI was higher in patients over 60 years old (1.27), in those with arterial aneurysms (mean: 1.11), and in those diagnosed with hypertension (mean: 1.13). When only patients over 60 years old were considered, those diagnosed with connective tissue diseases had the highest ATI. At multivariate regression analysis, increasing age (p < 0.05), presence of arterial aneurysms (p < 0.05), and hypertension (p < 0.05) were independently associated with ATI. CONCLUSIONS: The ATI may be a promising tool in diagnostic evaluation, cardiovascular risk stratification, medical or surgical management, and prognostic assessment in several non-atherosclerotic vascular conditions. Further studies with longitudinal design and larger cohorts are needed to validate the role of ATI in the full spectrum of vascular diseases.

Serum Uric Acid, Hypertriglyceridemia, and Carotid Plaques: A Sub-Analysis of the URic Acid Right for Heart Health (URRAH) Study.

High levels of serum uric acid (SUA) and triglycerides (TG) might promote high-cardiovascular-risk phenotypes, including subclinical atherosclerosis. An interaction between plaques xanthine oxidase (XO) expression, SUA, and HDL-C has been recently postulated. Subjects from the URic acid Right for heArt Health (URRAH) study with carotid ultrasound and without previous cardiovascular diseases (CVD) (n = 6209), followed over 20 years, were included in the analysis. Hypertriglyceridemia (hTG) was defined as TG ≥ 150 mg/dL. Higher levels of SUA (hSUA) were defined as ≥5.6 mg/dL in men and 5.1 mg/dL in women. A carotid plaque was identified in 1742 subjects (28%). SUA and TG predicted carotid plaque (HR 1.09 [1.04-1.27], p < 0.001 and HR 1.25 [1.09-1.45], p < 0.001) in the whole population, independently of age, sex, diabetes, systolic blood pressure, HDL and LDL cholesterol and treatment. Four different groups were identified (normal SUA and TG, hSUA and normal TG, normal SUA and hTG, hSUA and hTG). The prevalence of plaque was progressively greater in subjects with normal SUA and TG (23%), hSUA and normal TG (31%), normal SUA and hTG (34%), and hSUA and hTG (38%) (Chi-square, 0.0001). Logistic regression analysis showed that hSUA and normal TG [HR 1.159 (1.002 to 1.341); p = 0.001], normal SUA and hTG [HR 1.305 (1.057 to 1.611); p = 0.001], and the combination of hUA and hTG [HR 1.539 (1.274 to 1.859); p = 0.001] were associated with a higher risk of plaque. Our findings demonstrate that SUA is independently associated with the presence of carotid plaque and suggest that the combination of hyperuricemia and hypertriglyceridemia is a stronger determinant of carotid plaque than hSUA or hTG taken as single risk factors. The association between SUA and CVD events may be explained in part by a direct association of UA with carotid plaques.

Biomarkers of Neutrophil Activation in Patients with Symptomatic Chronic Peripheral Artery Disease Predict Worse Cardiovascular Outcome.

Neutrophils play a role in cardiovascular (CV) disease. However, relatively scant evidence exists in the setting of peripheral artery disease (PAD). The aims of this study were to measure biomarkers of neutrophil activation in patients with symptomatic chronic PAD compared with healthy controls, to assess their association with PAD severity, and to evaluate their prognostic value in patients with PAD. The following circulating markers of neutrophil degranulation were tested: polymorphonuclear neutrophil (PMN) elastase, neutrophil gelatinase-associated lipocalin (NGAL), and myeloperoxidase (MPO). Neutrophil extracellular traps (NETs) were quantified by measuring circulating MPO-DNA complexes. Patients with PAD underwent a comprehensive series of vascular tests. The occurrence of 6-month major adverse CV (MACE) and limb events (MALE) was assessed. Overall, 110 participants were included, 66 of which had PAD. After adjustment for conventional CV risk factors, PMN-elastase (adjusted odds ratio [OR]: 1.008; 95% confidence interval [CI]: 1.002-1.015; p = 0.006), NGAL (adjusted OR: 1.045; 95%CI: 1.024-1.066; p < 0.001), and MPO (adjusted OR: 1.013; 95%CI: 1.001-1.024; p = 0.028) were significantly associated with PAD presence. PMN-elastase (adjusted hazard ratio [HR]: 1.010; 95%CI: 1.000-1.020; p = 0.040) and MPO (adjusted HR: 1.027; 95%CI: 1.004-1.051; p = 0.019) were predictive of 6-month MACE and/or MALE. MPO displayed fair prognostic performance on receiver operating characteristic (ROC) curve analyses, with an area under the curve (AUC) of 0.74 (95%CI: 0.56-0.91) and a sensitivity and specificity of 0.80 and 0.65, respectively, for a cut-off of 108.37 ng/mL. MPO-DNA showed a weak inverse correlation with transcutaneous oximetry (TcPO2) on proximal foot (adjusted ρ -0.287; p = 0.032). In conclusion, in patients with symptomatic chronic PAD, enhanced neutrophil activity may be associated with an increased risk of acute CV events, rather than correlate with disease severity. Further research is needed to clarify the role of neutrophils in PAD natural history.

In postmenopausal women, lower limb peripheral arterial disease, assessed by ankle-brachial index, may be a strong predictor of cardiovascular risk.

BACKGROUND: Lower limb peripheral arterial disease (PAD) is a leading atherosclerotic disease in the elderly. However, awareness of the disease is poor, particularly in women. METHODS: In this retrospective, cross-sectional study, postmenopausal women referred to our Angiology Division were tested for PAD, defined as an "ankle-brachial index" (ABI) ≤0.9 or ≥1.4 (in the latter case with a "toe-brachial index" <0.7), or a history of lower limb arterial revascularization. Aim of our study was to assess cardiovascular (CV) risk profile in postmenopausal women with and without PAD, and to evaluate the role of PAD and six classic CV risk factors (CVRFs), namely age, current smoking, hypertension, dyslipidaemia, severe chronic renal failure, and diabetes in predicting CV disease (CVD), defined as coronary artery disease and/or cerebrovascular disease. RESULTS: Overall, 850 patients were included, 39.4% of whom with PAD. Compared with women without PAD, those with PAD were older (75.2 vs 66 years, respectively; p <0.001), and displayed higher rates of other CVRFs (p <0.001 for each). A personal history of CVD was reported in 18.8% of women with PAD and in 6.1% of those without PAD (p <0.001). At multivariate regression analysis, PAD (odds ratio [OR]: 2.15; 95% confidence interval [CI]: 1.33-3.47), and hypertension (OR: 2.20; 95%CI: 1.24-3.88) were the strongest factors associated with CVD presence. CONCLUSIONS: PAD is a strong marker of CVD in this selected series of postmenopausal women. If confirmed in the general population, PAD screening through ABI calculation may be considered for CV risk assessment in postmenopausal women.

Subclinical HMOD in Hypertension: Left Ventricular Diastolic Dysfunction.

Arterial hypertension represents an important risk factor for the development of cardiac, vascular and renal events, predisposing to heart failure, acute coronary syndromes, peripheral artery disease, stroke, and chronic renal disease. Arterial hypertension leads to the development of subclinical hypertension mediated organ damage (HMOD) which has prognostic relevance and may influence the choice of treatment options. Alterations of cardiac structure and function represent the more widely assessed form of HMOD. This manuscript will focus on the diagnostic opportunities, prognostic significance and treatment of diastolic dysfunction alterations.
