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…

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…

2014

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…

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…

015: Relation between platelet activation and inflammation indexes measured on admission and new onset atrial fibrillation in patients with acute myo…

2013

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…
