Endovascular management of carotid and vertebral artery dissections with new generation double-mesh stent and protection systems – single-center earl…

2019

Introduction Symptomatic dissections (SD) of cervical arteries are still a therapeutic problem. Although endovascular management (EM) is currently a preferred method of treatment of SD, complications associated with this method of treatment in published reports are quite frequent (3-16%). Aim In this retrospective study we analyzed the results of EM with novel, double-mesh stent and protection systems (PS) for SD of the internal carotid (IC) or vertebral arteries (VA) that coexisted with hemodynamically significant stenosis or aneurysmatic dilatation of the dissected artery. Material and methods We evaluated the results of EM in 19 patients (men 15, median age: 55, range: 25-83), presenting…

Tumor Oxygenation Under Normobaric and Hyperbaric Hyperoxia

1997

Tumor hypoxia is an important factor limiting the efficiency of sparsely ionizing ra-diation and O2-dependent chemotherapy. Since the tumor pO2 is the result of a dynamic steady state between oxygen supply and O2 consumption of the tumor tissue, hypoxia could be reduced either by increasing the O2-supply or by reducing the O2 demand of the tumor cells. The O2 supply can be improved for instance by (i) increasing the arterial oxy-gen partial pressure, (ii) improving (and homogenizing) the tumor perfusion, or (iii) en-hancing the O2 release from blood into the tissue by right-shifting the HbO2 dissociation curve. Theoretically, it should also be possible to improve tumor oxygenation by a rela…

3104Associations between cardiovascular disease, cancer and very low hdl cholesterol in the reasons for geographical and racial differences in stroke…

2017

AIMS: Relatively little is known about the health outcomes associated with very low plasma concentrations of high density lipoprotein cholesterol (HDL-C) mainly because of the small numbers of individuals with such extreme values included in clinical trials. We therefore investigated the association between low and very low HDL-C concentration at baseline and incident all-cause-mortality, death from malignant disease (i.e. cancer), and with fatal or non-fatal incident coronary heart disease (CHD) in individuals from the Reasons for Geographical And Racial Differences in Stroke (REGARDS) study. METHODS AND RESULTS: Analysis was based on 21,751 participants from the REGARDS study who were fre…

Atherogenic lipoprotein phenotype and LDL size and subclasses in drug-naïve patients with early rheumatoid arthritis.

2009

Abstract Objective : Subjects with rheumatoid arthritis (RA) have increased cardiovascular risk and may show atherogenic forms of dyslipidemia. The present study investigated whether patients with early RA, beyond alterations in plasma lipids, also show lower LDL size and altered LDL subclass distribution. Design and Methods We identified 25 subjects with RA (47±8 years, body mass index (BMI) 25±4kg/m 2 ) by the American College of Rheumatology diagnostic criteria, with a disease durations Results As compared to controls RA patients had higher plasma triglycerides (1.8±0.5 vs. 1.0±0.5mmol/L, p p =0.0027), while total- and LDL-cholesterol concentrations were similar. LDL particle size was lo…

Familial Combined Hyperlipidemia, Metabolic Syndrome and Cardiovascular Disease

2006

Our aim was to investigate the relationship between metabolic syndrome and cardiovascular disease (i.e., survivors of myocardial infarction) in patients with familial combined hyperlipidemia (FCH). We compared a group of 20 male patients with FCH who had survived a myocardial infarction with two other groups matched for age and body mass index, comprising 20 individuals with FCH who had not had a myocardial infraction and 20 control subjects. Plasma lipid, glucose, and insulin levels were determined. Metabolic syndrome was judged to present on the basis of World Health Organization (WHO) and National Cholesterol Education Program-Adult treatment panel (NCEP-ATPIII) criteria. Differences bet…

Should we measure routinely oxidised and atherogenic dense low-density lipoproteins in subjects with type 2 diabetes?

2010

Beyond low-density lipoprotein (LDL)-cholesterol concentrations, in recent years, several clinical studies have shown that both oxidised and small, dense LDL have a strong predictive role for the presence of vascular atherosclerosis. These two lipid parameters seem to have a synergistic impact on cardiovascular risk, with a greater importance in patients at higher-risk, such as those with type-2 diabetes. Increased levels of oxidised and small, dense LDL levels are a feature of diabetic dyslipidaemia, and small, dense LDL have been shown to be a good predictor of future cardiovascular events, at both univariate and multivariate analyses. On the other hand, although the association of oxidis…

Do We Still Need Organic Nitrates?⁎⁎Editorials published in the Journal of the American College of Cardiologyreflect the views of the authors and do …

2007

Organic nitrates are still quite frequently used for the treatment of acute and chronic angina, and acute and chronic congestive heart failure. When given acutely, their effectiveness is undisputable; however, their long-term efficacy is substantially limited due to the development of tolerance ([1

Dual lumen microcatheters for recanalisation of chronic total occlusions: A EuroCTO Club expert panel report

2021

Dual lumen microcatheters (DLMC) have become indispensable tools in the setting of percutaneous coronary intervention (PCI) of chronic total occlusion (CTO). Other than allowing preservation and treatment of bifurcated coronary branches within or in the proximity of the CTO-body, they enable the use of modified parallel wiring, antegrade dissection and re-entry, collateral selection and retrograde negotiation of the distal CTO-cap. This Euro-CTO consensus document describes current DLMCs and suggests a practical guide to anatomies and techniques in which these devices are applicable.
