Continuous cardiac afterload evaluation could represent a useful tool during general anesthesia (GA) to titrate vasopressor effect. Using beat to beat descending aortic pressure(P)/flow velocity(U) loop obtained from esophageal Doppler and femoral pressure signals might allow to track afterload changes. Methods We defined three angles characterizing the PU loop (alpha, beta and Global After-Load Angle (GALA)). Augmentation index (AIx) and total arterial compliance (Ctot) were measured via radial tonometry. Peripheral Vascular Resistances (PVR) were also calculated...

AIMS: Renal dysfunction is a risk factor for cardiovascular disease, including atrial fibrillation (AF) and mortality. However, the exact pathobiology linking different renal dysfunction measures, such as albumin excretion or glomerular filtration rate (GFR), to cardiovascular- and AF risk are unclear. In this study, we investigated the association of several renal function measures and incident AF, and whether the relation between renal measures and outcomes is modified by AF. METHODS AND RESULTS: We examined 8265 individuals (age 49 ± 13 years, 50% women) included in the PREVEND study...

Small, isolated, and/or peripheral populations are expected to harbour low levels of genetic variation and may therefore have reduced adaptability to environmental change, including climate warming. In the Arctic, global warming has already caused vegetation change across the region and is acting as a significant stressor on Arctic biodiversity. Many of the rare plants in the Arctic are relicts from early Holocene warm periods, but their ability to benefit from the current warming is dependent on the viability of their populations...

Bioresorbable scaffolds have the potential to overcome several problems associated with metallic stents. Bioresorbable poly-L-lactic acid (PLLA) scaffold implantation for the treatment of peripheral artery disease has already been reported in animal models and clinical trials; however, no studies comparing PLLA scaffolds and bare metal stents (BMSs) with regard to early vascular morphological changes, identified using intravascular ultrasound (IVUS) analysis, have been reported. In this study, PLLA scaffolds and BMSs were implanted bilaterally in iliac arteries of five miniature pigs...

BACKGROUND: Elevated levels of C-reactive protein (CRP) are known to be associated with cardiovascular (CV) morbidity and mortality in older adults, however, there seems to be heterogeneity of this association across subsets of individuals. We aim to assess the effects of interactions between CRP and one of the following traditional CV risk factors regarding all-cause mortality in unselected elderly men and women: age, sex, body mass index, diabetes, and hypertension. PATIENTS AND METHODS: Three hundred and forty-four general practitioners all over Germany enrolled 6,817 unselected participants, aged 65 years or older, and performed thorough examinations, including CRP measurement at baseline (getABI study)...

BACKGROUND: Cardiovascular risk in type 1 diabetes mellitus (T1DM) is associated with endothelial dysfunction, inflammation, and altered immunity. CD4(+) CD28(null) T-cells are a subset of long-lived cytotoxic CD4(+) T-lymphocytes with proatherogenic and plaque-destabilizing properties. We hypothesized that the frequency of CD4(+) CD28(null) T-cells may be altered in T1DM and related to vascular complications. AIM: To assess the percentage of CD4(+) CD28(null) T-lymphocytes in children and adolescents with T1DM and their relation to vascular structure and glycemic control...

INTRODUCTION: The 2015 advanced cardiac life support update continues to advocate administering epinephrine during cardiac arrest. The goal of our study is to determine if prehospital intraosseous (IO) access results in shorter time to epinephrine than prehospital peripheral intravenous (PIV) access. METHODS: The out-of-hospital cardiac arrest (OHCA) database of a large, urban, fire-based emergency medical services system was searched for consecutive cases of OHCA between January 2013 and December 2015...

The increasing prevalence of hypertension, a significant cause of disability and premature death throughout the world, is a major public health concern. This is especially true for the subset of patients who suffer from resistant hypertension, which is associated with a fourfold greater risk of cardiovascular events as compared to those hypertensive patients able to achieve target blood pressure. Though quite daunting in number and ill effect, hypertension remains the most common and the most important modifiable risk factor for coronary heart disease, congestive heart failure, peripheral vascular disease, stroke, and chronic kidney disease...

INTRODUCTION: In adults, central blood pressure (cBP) is reported to associate target organ damages (TODs) rather than peripheral blood pressure (pBP). However, data regarding the association of pre-clinical TODs with cBP and pBP in pediatric populations are scarce. AIM: To evaluate in children and adolescents the importance of cBP and pBP levels, in terms of their association with hemodynamic and vascular changes. METHODS: 315 subjects [age (mean/range) 12/8-18 years] were included...

A 55-year-old male with peripheral arterial disease underwent angioplasty of the right lower limb arteries via antegrade femoral access. Angio-Seal(®) closure device was used to treat the puncture site, whereby the intravascular sealing anchor accidentally embolized into the malleolar region of the right posterior tibial artery. Successful retrieval of the anchor was accomplished by a SpiderFX embolic protection device. This technique may be a useful approach to retrieve embolized foreign bodies via endovascular access...

Antiplatelet therapy reduces the risk of myocardial infarction, stroke, and vascular death in patients who have symptomatic peripheral artery disease. However, a subset of patients who take aspirin continues to have recurrent cardiovascular events. There are few data on cardiovascular outcomes in patients with peripheral artery disease who manifest aspirin resistance. Patients with peripheral artery disease on long-term aspirin therapy (≥4 wk) were tested for aspirin responsiveness by means of the VerifyNow Aspirin Assay...

BACKGROUND: Computed tomography angiography (CTA) is the test of choice for pre-procedure imaging of transcatheter aortic valve replacement (TAVR) candidates. The iodinated contrast required, however, increases the risk of renal dysfunction in patients with pre-existing renal failure. Ferumoxytol is a magnetic resonance imaging (MRI) contrast agent that can be used with renal failure. Its long vascular resonance time allows gated MRA sequences that approach CTA in image quality. We present respiratory and cardiac gated MRA enabled by ferumoxytol that can be post-processed in an analogous fashion to CTA...

Candida auris and C. haemulonii are closely related, multidrug-resistant emerging fungal pathogens that are not readily distinguishable with phenotypic assays. We studied C. auris and C. haemulonii clinical isolates from 2 hospitals in central Israel. C. auris was isolated in 5 patients with nosocomial bloodstream infection, and C. haemulonii was found as a colonizer of leg wounds at a peripheral vascular disease clinic. Liberal use of topical miconazole and close contact among patients were implicated in C...

More than half of deaths in end-stage kidney disease (ESKD) patients are due to cardiovascular disease. Elevated fibroblast growth factor 23 (FGF-23) was found to be associated with mortality in hemodialysis (HD) patients and correlates with peripheral calcification. Aortic calcification is associated with coronary artery calcification. Both aortic and peripheral vascular calcifications were associated with mortality in chronic kidney disease. We aimed to investigate the relation between intact FGF-23 and cardiovascular calcification in patients with ESKD who were maintained on regular HD...
