BACKGROUND: Recent observations have suggested a decline in vulnerable carotid artery and iliofemoral atherosclerotic plaque characteristics over the past decade. The aim of this study was to determine whether, in the presence of clinically manifest carotid or peripheral artery disease, secondary adverse cardiovascular events decreased over this period. METHODS: Patients included in the Athero-Express biobank between 2003 and 2012 were analysed. During 3-year follow-up, composite cardiovascular endpoints were documented yearly, including: myocardial infarction, coronary interventions, stroke, peripheral interventions and cardiovascular death...

BACKGROUND: The cause for discrepancy in the clinical presentation and outcome of coronary artery disease (CAD) between men and women is not established. Different prevalences of risk factors or specific sex-related atherosclerotic aspects have been advocated as possible explanations. We investigated coronary plaque morphology looking at possible differences in plaque vulnerability between men and women with stable CAD. PATIENTS AND METHODS: We retrospectively collected and analyzed clinical data and coronary plaque morphology by frequency-domain optical coherence tomography in men and women with stable CAD...

BACKGROUND: Atherosclerotic plaque rupture is the culprit event which underpins most acute vascular syndromes such as acute myocardial infarction. Novel biomarkers of plaque rupture could improve biological understanding and clinical management of patients presenting with possible acute vascular syndromes but such biomarker(s) remain elusive. Investigation of biomarkers in the context of de novo plaque rupture in humans is confounded by the inability to attribute the plaque rupture as the source of biomarker release, as plaque ruptures are typically associated with prompt down-stream events of myocardial necrosis and systemic inflammation...

BACKGROUND AND AIMS: Dynamic contrast-enhanced MR imaging (DCE-MRI) provides a noninvasive approach to the functional status of carotid adventitial vasa vasorum. Contrast extravasation rate, or K(trans), derived from kinetic modeling of adventitial enhancement, has been correlated with plaque neovascularization and inflammation. This study sought to clarify the clinical implications of K(trans) by evaluating its relationship with documented cardiovascular events (CVE). METHODS: Seventy patients with carotid plaque at clinical ultrasound examination were recruited and imaged with a previously-described bright-blood DCE-MRI protocol (spatial resolution: 0...

In this study, we verify the association between the rs1333049 single nucleotide polymorphism (9p21.3) within CDKN2A-CDKN2B and coronary artery disease (CAD) in an Italian population. We replicated rs1333049_G allele association with a significantly reduced risk of CAD (OR = 0.816; 95% confidence interval [0.705-0.945]; p = 0.0065) in 711 CAD patients and 755 normal healthy individuals. This effect is maintained even stratifying patients by gender and by risk factors. A significant association was found with age of CAD onset...

Increase of thrombus in the coronary arteries is positively correlated with the level of heat-shock protein 72 (HSP72) in the blood of patients with acute myocardial infarction (AMI). Platelet aggregation participates in thrombus formation on ruptured plaque in AMI. In this study, we aimed to clarify the role of HSP72 in thrombus formation by evaluating the effects of HSP72 on platelet aggregation. Platelet aggregation activities were measured in platelet-rich plasma obtained from male Sprague-Dawley rats with or without the platelet activators, such as adenosine diphosphate (ADP), collagen, thrombin receptor-activating peptide-6 (TRAP-6), ristocetin, and arachidonic acid...

Rationale: Inflammation is a key contributor to atherosclerosis. MicroRNA-146a (miR-146a) has been identified as a critical brake on pro-inflammatory NF-κB signalling in several cell types, including endothelial cells and bone marrow-derived cells. Importantly, miR-146a expression is elevated in human atherosclerotic plaques, and polymorphisms in the miR-146a pre-cursor have been associated with risk of coronary artery disease. Objective: To define the role of endogenous miR-146a during atherogenesis. Methods and Results: Paradoxically, Low-density lipoprotein receptor (Ldlr)(-/-) mice deficient in miR-146a develop less atherosclerosis, despite having highly elevated levels of circulating pro-inflammatory cytokines...

We report a case in which strict anticoagulant therapy management was useful for a recurrent in-stent thrombosis after carotid artery stenting (CAS). An 84-year-old man presented with cognitive decline that progressed rapidly over two months. Head magnetic resonance imaging showed an acute-stage infarct occurring frequently in the right cerebral hemisphere, and he underwent hospitalization and treatment. On neck magnetic resonance angiography (MRA), severe stenosis was found at the origin of the right internal carotid artery...

Coronary artery disease has a significant genetic predisposition, which mainly results from atherosclerosis. Miniature pig is an excellent model to investigate atherosclerosis. This study investigated whether the occurrence and development of atherosclerosis in the Wuzhishan miniature pigs (WZSPs) that were closely bred 12 generations had better consistency. The WZSPs (n = 9) were fed a high-cholesterol and high-fat diet (HCFD). After continuous feeding, 3 WZSPs each were sacrificed at 6, 8, and 12 months, respectively, and the general clinical manifestations and serological indexes were detected...

Personality traits are associated with major adverse coronary events (MACE) in patients with coronary artery disease (CAD). However, the link between personality traits and intravascular morphology in CAD patients is poorly understood. This study investigated the relationship between personality traits, specifically Type A behavior pattern and Type D personality, and plaque vulnerability. After adjustment for demographic and clinical factors, multivariable regression analysis showed no association between Type A and optical coherence tomography indices...

Introduction Studies conducted in the recent past have demonstrated the role of inflammation, obesity and dysfunctional insulin signaling as contributing factors in the pathogenesis of acute coronary syndrome (ACS). However, pharmacological interventions targeting a single pathway have not proven useful in the long run. This indicates that a synergism occurs between the various risk factors and hence calls for a combinatorial approach. This study was planned to study the interplay, if any, between pregnancy associated plasma protein-A (PAPP-A), inflammation and adiposity in patients with ACS...

BACKGROUND: Coronary artery calcification (CAC) is a predictor of cardiovascular events and plaque burden and is closely associated with chronic inflammation. Interleukin (IL)-37 is a newly discovered member of the IL-1 family and is considered an anti-inflammatory cytokine. Our recent study on mice indicated that IL-37 could attenuate atherosclerosis and vascular calcification, which suggests that IL-37 could be associated with the development of atherosclerosis and related diseases...

Coronary plaque rupture is the most common cause of acute coronary syndrome. However, the timely biomarker-based diagnosis of plaque rupture remains a major unmet clinical challenge. Balloon dilatation and stent implantation during percutaneous coronary intervention (PCI) could cause plaque injury and rupture. Here we aimed to assess the possibility of circulating microRNAs (miRNAs) as biomarkers of acute coronary plaque rupture by virtue of the natural model of PCI-induced plaque rupture. Stable coronary artery disease patients underwent PCI with single stent implantation were recruited and a three-phase approach was conducted in the present study: (i) profiling of plasma miRNAs in a group of patients before (0 h) and after balloon dilatation for 1 h (1 h vs...

OBJECTIVES: To report adverse event rates after rotational atherectomy (RA) with contemporary drug-eluting stent (DES) implantation and compare RA to cutting balloon (CB) angioplasty and balloon-only angioplasty (BA) in the all-comers ADAPT-DES trial. BACKGROUND: Percutaneous coronary intervention (PCI) of calcified lesions is increasingly common and is associated with a high risk of adverse events. RA can ablate calcified plaque and facilitate stent delivery; however, in conjunction with first-generation DES, RA was not superior to BA alone in regard to adverse events...

Several large-scale genome-wide association studies have identified single-nucleotide polymorphisms in the genomic region of A Disintegrin And Metalloproteinase with ThromboSpondin type 1 repeats (ADAMTS)-7 and associations to coronary artery disease. Experimental studies have provided evidence for a functional role of ADAMTS-7 in both injury-induced vascular neointima formation and development of atherosclerotic lesions. However, whether ADAMTS-7 is associated with a specific plaque phenotype in humans has not been investigated...
