Les anti-agrégants plaquettaires au cours du syndrome coronarien aigu. Données des grandes études
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…
Prise en charge au long cours par les anti-agrégants plaquettaires oraux après un syndrome coronaire aigu
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…
0432: Impact of admission hyperglycemia on one-year mortality in non-diabetic patients admitted for rescue PCI: Data from the “Observatoire des infarctus de Côte d’Or”
BackgroundRescue percutaneous coronary intervention (PCI) is associated with improved clinical outcomes for ST-segment myocardial infarction (STEMI) patients after failed fibrinolysis therapy. Hyperglycemia on admission has been shown to be a powerful predictor of mortality after acute myocardial infarction, particularly in non-diabetic patients. The aim of our study was to assess the predictive value of admission glucose levels on long-term mortality in patients with rescue PCI.Patients and MethodsFrom the “Observatoire des infarctus de Côte d’Or” (RICO) survey, 510 consecutive non-diabetic STEMI patients admitted to the intensive care unit for rescue PCI after failed fibrinolysis therapy …
The Free Oxygen Radicals Test (FORT) to assess circulating oxidative stress in patients with acute myocardial infarction

Several methods have been developed for the direct or indirect measurement of oxygen free radical and its by-products. The current study was designed to validate the new Free Oxygen Radicals Test (FORT) and to investigate the potential relationships between ROS and clinical or biological factors in male patients with acute myocardial infarction (AMI). Methods: We analysed FORT values in samples from 66 patients with AMI. Results: FORT values ranged from 324 to 1198 FORT units, with a median value of 581 (494-754) FORT units.…
SYNTAX score is associated with in-hospital mortality as assessed by GRACE risk score in patients with acute myocardial infarction
Relationship between fragmented QRS and no-reflow, infarct size, and peri-infarct zone assessed using cardiac magnetic resonance in patients with myocardial infarction.
International audience; BACKGROUND: The relation between fragmented QRS complex (fQRS) and cardiac magnetic resonance parameters is poorly documented in ischemic cardiopathy. METHODS: Among 209 consecutive patients, those with fQRS were compared with those without fQRS. Cardiac magnetic resonance studies with late gadolinium-enhanced sequences were done during the week after acute myocardial infarction. RESULTS: fQRS was present in 113 (54%) patients, and associated with a significantly lower left ventricular ejection fraction, increased left ventricular volumes, a larger infarct size (IS), and a larger peri-infarct zone. Microvascular obstruction was more frequent in patients with fQRS (62…

Incidence and prognostic significance of silent atrial fibrillation in acute myocardial infarction
article Background: Silent atrial fibrillation (AF) has been suggested to be frequent after acute myocardial infarction (MI). Continuous ECG monitoring (CEM) has been shown to improve AF screening in patients at risk of stroke. Objectives: We aimed to assess the incidence and prognosis of silent AF in patients with acute MI. Methods:All the consecutive patients with acute MI were prospectively analyzed by CEM ≥ 48 h after admission. Silent AF was defined as asymptomatic episodes lasting at least 30 s. The population was divided into three groups: no-AF, silent AF and symptomatic AF. Results:Among the 849 patients, 135(16%) developedsilentAF and45(5%)symptomatic AF.Comparedwith the no-AF gro…
Impact of admission hyperglycemia on one-year mortality in non-diabetic patients admitted for rescue PCI
New insights into symptomatic or silent atrial fibrillation complicating acute myocardial infarction
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…
015: Relation between platelet activation and inflammation indexes measured on admission and new onset atrial fibrillation in patients with acute myocardial infarction
ObjectivePlatelet activation is present in atrial fibrillation (AF), but there is some debate whether this is due to AF itself and/or to underlying cardiovascular diseases. We aim to determine the association between a marker of platelet reactivity (mean platelet volume (MPV)) and systemic inflammation (CRP) measured on admission, and new onset episode of AF in patients with MI.Patients and methodsProspective cohort of 4994 consecutive patients with AMI. Patients with paroxysmal or persistent AF were excluded.Results426 (8.5%) patients were diagnosed with a new onset of AF during the in-hospital-stay (mean stay 3±2 days). These patients were older (75 vs 65, p<0.001), predominantly male, an…

Prognosis of silent atrial fibrillation after acute myocardial infarction at 1-year follow-up
Silent atrial fibrillation (AF), assessed by continuous ECG monitoring (CEM), has recently been shown to be common in acute myocardial infarction (AMI), and associated with higher hospital mortality. However, the long-term prognosis is still unknown. We aimed to assess 1-year prognosis in patients experiencing silent AF in AMI.All consecutive patients with AMI who were prospectively analysed by CEM during the first 48 h after admission and who survived at hospital discharge were included. Silent AF was defined as asymptomatic episodes lasting at least 30 s. Patients were followed up at 1 year for cardiovascular (CV) outcomes.Among the 737 patients analysed, 106 (14%) developed silent AF and…
Incidence, Predictive Factors, and Prognostic Impact of Silent Atrial Fibrillation After Transcatheter Aortic Valve Implantation.
New onset atrial fibrillation post-transcatheter aortic valve implantation (TAVI) is common and is associated with adverse outcomes. However, silent atrial fibrillation (AF) is poorly documented in the context. This study sought to evaluate the incidence, predictive factors, and prognostic value of Silent AF post-TAVI. All the consecutive patients with TAVI were prospectively analyzed by continuous electrocardiogram monitoring≥48 hours after implantation. Silent AF was defined as asymptomatic episodes lasting at least 30 seconds. The population was divided into 3 groups: history of AF, no-AF, and silent AF. Among the 206 patients implanted with TAVI, 19 (16.1%) developed silent AF. Compared…
