Serum brain-derived neurotrophic factor and platelet activation evaluated by soluble P-selectin and soluble CD-40-ligand in patients with acute myoca…

2009

Little is known about the role of neurotrophins (NT) under adult vascular homeostasis in normal and pathological conditions. The NT family, including nerve growth factor and brain-derived neurotrophic factor (BDNF) are expressed in atherosclerotic vessels. Previous studies demonstrated that plasma BDNF levels were increased in the coronary circulation in patients with unstable angina. However, the role of BDNF during the onset and evolution of unstable angina remains to be elucidated. The objective of this study was to evaluate the relationship between BDNF, functional parameters and biological markers associated with inflammatory processes and platelet activation. BDNF serum levels were as…

Les anti-agrégants plaquettaires au cours du syndrome coronarien aigu. Données des grandes études

2010

Cardiovascular disease is the leading cause of early death and morbidity in developed countries and is becoming a growing problem in many developing countries. Currently, anti-coagulants play a major role in the management of the acute phase in association or not with reperfusion strategies. The combination of clopidogrel and aspirin, in accordance with the results of large randomized trials, is the treatment of reference. However two new drugs, a thienopyridine (prasugrel), and a cyclo-pentyl-triazolo-pyridine (ticagrelor) have shown their interest in major studies in comparison with clopidogrel. As a result, several effective P2Y12 receptor antagonist anti-platelet agents are now availabl…

Psychosocial factors burden in workers with acute cerebro- or cardiovascular events: A multidisciplinary prospective pilot study

2018

Introduction Psychosocial stress at work has been proposed as a risk factor for cerebro- and cardiovascular event (CVE) such as stroke or acute myocardial infarction (MI). However, data on psychosocial factors (PSF) profile in patients with CVE are scarce. In a multidisciplinary approach, we aimed to characterize PSF burden in patients with acute stroke or MI. Patients In a prospective pilot study, 45 patients aged  Results Among the 44 patients included, 77% had acute MI and 23% stroke. Mean age was 50 years, 77% were male, 43% were current smokers, 39% had hypertension, 41% hypercholesterolemia and 36% obesity. Education level was at 4,65 (secondary education), and most (41%) had low soci…

Nitric oxide synthase inhibition and oxidative stress in cardiovascular diseases: Possible therapeutic targets?

2013

International audience; Nitric oxide (• NO) is synthetized enzymatically from L-arginine (L-Arg) by three NO synthase isoforms, iNOS, eNOS and nNOS. The synthesis of NO is selectively inhibited by guanidino-substituted analogs of L-Arg or methylarginines such as asymmetric dimethylarginine (ADMA), which results from protein degradation in cells. Many disease states, including cardiovascular diseases and diabetes, are associated with increased plasma levels of ADMA. The N-terminal catalytic domain of these NOS isoforms binds the heme prosthetic group as well as the redox cofactor, tetrahydrobiopterin (BH 4) associated with a regulatory protein, calmodulin (CaM). The enzymatic activity of NOS…

Involvement of Autonomic Nervous System in New-Onset Atrial Fibrillation during Acute Myocardial Infarction

2020

Background: Atrial fibrillation (AF) is common after acute myocardial infarction (AMI) and associated with in-hospital and long-term mortality. However, the pathophysiology of AF in AMI is poorly understood. Heart rate variability (HRV), measured by Holter-ECG, reflects cardiovascular response to the autonomic nervous system and altered (reduced or enhanced) HRV may have a major role in the onset of AF in AMI patients. Objective: We investigated the relationship between autonomic dysregulation and new-onset AF during AMI. Methods: As part of the RICO survey, all consecutive patients hospitalized for AMI at Dijon (France) university hospital between June 2001 and November 2014 were analyzed …

Prise en charge au long cours par les anti-agrégants plaquettaires oraux après un syndrome coronaire aigu

2007

Cardiovascular disease is the primary cause of early death and morbidity in the industrialized world and is becoming a growing problem in many developing countries. Coagulation inhibitors play a major role in the management of the acute phase of ACS whether in association with reperfusion strategies or not. Currently, and in accordance with the results of major randomised studies, for medium and long-term management, the association of Clopidogrel and aspirin is the treatment of choice. However, despite the recognised benefits of this therapeutic strategy and above all the recommendations of learned societies, which have placed this bi-therapy in class I, according to national and internati…

Combining Body Mass Index With Measures of Central Obesity in the Assessment of Mortality in Subjects With Coronary Disease

2013

Objectives This study sought to assess the mortality risk of patients with coronary artery disease (CAD) based on a combination of body mass index (BMI) and measures of central obesity. Background In CAD patients, mortality has been reported to vary inversely with BMI (“obesity paradox”). In contrast, central obesity is directly associated with mortality. Because of this bi-directional relationship, we hypothesized that CAD patients with normal BMI but with central obesity would have worse survival compared with subjects with other combinations of BMI and central adiposity. Methods We included 15,547 participants with CAD who took part in 5 studies from 3 continents. Multivariate stratified…

0197: Angiographically visible distal embolization is not linked with culprit lesion but with clinical characteristics

2016

Despite the recent improvements in percutaneous coronary intervention (PCI), angiographically visible distal embolization (AVDE) complicates 6 to 18% of ST elevation myocardial infarction (STEMI) treated with PCI, and is associated with poor clinical outcomes. Culprit lesion characteristics have been proved to be the main predictive factor of AVDE. But data regarding clinical characteristics predicting AVDE are lacking. We aimed to identify predictors of AVDE complicating PCI in STEMI management. 769 consecutive patients admitted for STEMI who underwent PCI were included. Clinical, angiographic and therapeutics characteristics were assessed for each patien. AVDE was defined as an abrupt ves…

Telomere length and cardiovascular disease

2010

SummaryTelomeres are structures composed of deoxyribonucleic acid repeats that protect the end of chromosomes, but shorten with each cell division. They have been the subject of many studies, particularly in the field of oncology, and more recently their role in the onset, development and prognosis of cardiovascular disease has generated considerable interest. It has already been shown that these structures may deteriorate at the beginning of the atherosclerotic process, in the onset and development of arterial hypertension or during myocardial infarction, in which their length may be a predictor of outcome. As telomere length by its nature is a marker of cell senescence, it is of particula…

0131 : Impact of overweight on anthracycline and trastuzumab-induced cardiotoxicity: experimental study in mice

2015

Trastuzumab (TRZ), a humanized monoclonal antibody against Human Epidermal Growth Factor Receptor 2 (HER2) oncogene, is believed to potentiate doxorubicin (DOX) cardiotoxicity, resulting in left ventricular dysfunction. Few data indicate that overweight could influence DOX-induced cardiotoxicity, and no study has already evaluated the impact of moderate overweight on the cardiotoxic effect of DOX alone or in combination with TRZ. Immediately after birth, litters of C57BL/6 mice were either maintained at 10 (normal litter, NL), or reduced to 3 (small litter, SL) in order to induce programming of ~15% overweight through postnatal overfeeding. At 4 months, in order to evaluate the potentiation…

New insights into symptomatic or silent atrial fibrillation complicating acute myocardial infarction

2015

International audience; Atrial fibrillation (AF) is the most frequent heart rhythm disorder in the general population and contributes not only to a major deterioration in quality of life but also to an increase in cardiovascular morbimortality. The onset of AF in the acute phase of myocardial infarction (MI) is a major event that can jeopardize the prognosis of patients in the short-, medium- and long-term, and is a powerful predictor of a poor prognosis after MI. The suspected mechanism underlying the excess mortality is the drop in coronary flow linked to the acceleration and arrhythmic nature of the left ventricular contractions, which reduce the left ventricular ejection fraction. The p…

Incremental predictive value of mean platelet volume/platelet count ratio in in-hospital stroke after acute myocardial infarction.

2017

IF 2.558; International audience; Stroke is a serious complication after acute myocardial infarction (AMI) and is associated with an increased risk of death. Though the pathophysiological mechanisms are not exactly known, increased inflammation and platelet reactivity could play an important role in the occurrence of stroke during AMI. We aimed to investigate the relationship between both mean platelet volume (MPV), a parameter of platelet function, and C-reactive protein (CRP) and the occurrence of in-hospital ischemic stroke (IHS) after AMI. Data were obtained from a French regional survey for AMI that included 5976 patients admitted to an intensive care unit (ICU) between 2001 and 2010. …

2011

Background After more than two decades of the AIDS epidemic, the spectrum of HIV-associated vascular diseases has considerably evolved from infectious disease with improved survival, to premature atherosclerosis. As a consequence, acute atherosclerosis complications, such as acute coronary and cerebrovascular syndromes (ACS and CVS) are currently growing. However, only few data are available on HIV-infected patients in the setting of ACS/CVS. The aim of the present study was to determine the prevalence of HIV, as well as the characteristics and hospital case fatality of HIV-infected patients with CVS and ACS. Methods From the French nationwide hospital medical information database, data fro…

0200: Predictors of angiographically visible distal embolization in ST elevation myocardial infarction patients treated by primary percutaneous coron…

2016

Aspiration thrombectomy during primary percutaneous coronary intervention (p-PCI) in ST elevation myocardial infarction (STEMI) has been proposed to restore myocardial reperfusion. But important controversies remain concerning the usefulness of thrombectomy to improve this perfusion. Our objective was to evaluate the impact of manual thrombectomy on the occur-rence of angiographically visible distal embolization (AVDE) during p-PCI in STEMI. 346 consecutive patients admitted for STEMI who underwent p-PCI and thrombectomy were included. Clinical, angiographic and therapeutics characteristics were assessed. AVDE was defined as an abrupt vessel closure occurring at any point during the PCI pro…

Reduced Rivaroxaban Dose Versus Dual Antiplatelet Therapy After Left Atrial Appendage Closure: ADRIFT a Randomized Pilot Study.

2020

Background: Percutaneous left atrial appendage closure (LAAC) exposes to the risk of device thrombosis in patients with atrial fibrillation who frequently have a contraindication to full anticoagulation. Thereby, dual antiplatelet therapy (DAPT) is usually preferred. No randomized study has evaluated nonvitamin K antagonist oral anticoagulant after LAAC, and we decided to evaluate the efficacy and safety of reduced doses of rivaroxaban after LAAC. Methods: ADRIFT (Assessment of Dual Antiplatelet Therapy Versus Rivaroxaban in Atrial Fibrillation Patients Treated With Left Atrial Appendage Closure) is a multicenter, phase IIb study, which randomized 105 patients after successful LAAC to eith…

Les admissions pour iatrogénie sévère en unité de soins intensifs de cardiologie : étude prospective sur 7244 patients

2013

Resume Introduction Les complications iatrogeniques sont definies comme des reactions nocives induites par l’utilisation d’un medicament, mais aussi comme complications suite aux techniques invasives ou a l’implantation de materiel. Les complications iatrogenes survenant durant un sejour hospitalier sont bien connues et associees a une augmentation de la duree du sejour hospitalier et de la mortalite. En revanche, il existe peu de donnees concernant la iatrogenie comme motif d’admission a l’hopital ; particulierement en soins intensifs cardiologiques. Les objectifs de cette etude sont : (a) d’analyser la prevalence de la iatrogenie et ses caracterisques ; (b) de connaitre le retentissement …

Pre-Infarction Angina and Outcomes in Non-ST-Segment Elevation Myocardial Infarction: Data from the RICO Survey

2012

BACKGROUND: The presence of pre-infarction angina (PIA) has been shown to confer cardioprotection after ST-segment elevation myocardial infarction (STEMI). However, the clinical impact of PIA in non-ST-segment elevation myocardial infarction (NSTEMI) remains to be determined. METHODS AND RESULTS: From the obseRvatoire des Infarctus de Côte d'Or (RICO) survey, 1541 consecutive patients admitted in intensive care unit with a first NSTEMI were included. Patients who experienced chest pain <7 days before the episode leading to admission were defined as having PIA and were compared with patients without PIA. Incidence of in-hospital ventricular arrhythmias (VAs), heart failure and 30-day mortali…

Smoking and FOS expression from blood leukocyte transcripts in patients with coronary artery disease.

2011

International audience; OBJECTIVE: Analysis of the leukocyte transriptome, in particular the Finkel-Biskis-Jinkins Osteosarcoma (c-Fos) gene, which has a prominent role in inflammation, provides new insights into atherosclerosis mechanisms. Although smoking is a major risk factor, the links between smoking status and coronary artery disease (CAD) remains unclear. We aimed to analyze the relationship between smoking status and c-Fos expression in circulating leukocytes of patients with CAD. METHODS: c-Fos expression was measured by RT-Q-PCR, from blood leukocytes of 239 consecutive patients after acute myocardial infarction (MI). The patients were asked about their smoking status and stratif…
