Silent and symptomatic atrial fibrillation,during the acute phase of myocardial infarction : determinants and role of arginine methylated and oxidati…
2015
Atrial fibrillation (AF) is a frequent complication of acute myocardial infarction (AMI) with a poorer prognosis. Silent atrial fibrillation has been suggested to be frequent after AMI. However, most part of the studies has targeted only paroxysmal or persistent AF. Thus, Reduced Nitric Oxide availability and endothelial dysfunction has been recently recognized as a possible contributor to altered prognosis in AF. Asymmetric dimethylarginine (ADMA) can inhibit nitric oxide synthase and leads to endothelial dysfunction, inflammation and oxidative stress in multiple cardiovascular diseases. However, any study has addressed the relationship between ADMA levels and the occurrence of AF in AMI.W…
Iron metabolism markers and l-arginine derivatives in coronary artery disease : highlighting, assessment and role of oxidative stress in acute myocar…

Myocardial infarction (MI) is mostly caused by complications of atherosclerosis, whose the development would be initiated by a dysfunction of the vascular endothelium, characterized by an inflammatory condition and oxidative stress.In this pathogenesis, iron interacts at different levels and also has a major role in the development of endothelial dysfunction. Hepcidin and erythroferrone (discovered earlier as the myonectin/CTRP 15) participate in a major way in regulating certain stages of iron metabolism.Asymmetric dimethylarginine (ADMA), a marker of endothelial dysfunction is associated with most cardiovascular risk factors. Symmetrical dimethyl-arginine (SDMA), its stereoisomer, has an …
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…
