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…
Blood transfusion and ischaemic outcomes according to anemia and bleeding in patients with non-ST-segment elevation acute coronary syndromes: Insight…
2020
Background: The benefits and risks of blood transfusion in patients with acute myocardial infarction who are anemic or who experience bleeding are debated. We sought to study the association between blood transfusion and ischemic outcomes according to haemoglobin nadir and bleeding status in patients with NST-elevation myocardial infarction (NSTEMI).Methods: The TAO trial randomized patients with NSTEMI and coronary angiogram scheduled within 72h to heparin plus eptifibatide versus otamixaban. After exclusion of patients who underwent coronary artery bypass surgery, patients were categorized according to transfusion status considering transfusion as a timevarying covariate. The primary isch…
Transient focal cerebral ischemia significantly alters not only EAATs but also VGLUTs expression in rats: relevance of changes in reactive astroglia
2010
The involvement of plasma membrane glutamate transporters (EAATs - excitatory aminoacid transporters) in the pathophysiology of ischemia has been widely studied, but little is known about the role of vesicular glutamate transporters (VGLUTs) in the ischemic process. We analyzed the expression of VGLUT1-3 in the cortex and caudate-putamen of rats subjected to transient middle cerebral artery occlusion. Western blot and immunohistochemistry revealed an increase of VGLUT1 signal in cortex and caudate-putamen until 3 days of reperfusion followed by a reduction 7 days after the ischemic insult. By contrast, VGLUT2 and 3 were drastically reduced. Confocal microscopy revealed an increase in VGLUT2…
The effectiveness of the Feldenkrais method: a systematic review of the evidence
2014
The Feldenkrais Method (FM) has broad application in populations interested in improving awareness, health, and ease of function.This review aimed to update the evidence for the benefits of FM, and for which populations. A best practice systematic review protocol was devised. Included studies were appraised using the Cochrane risk of bias approach and trial findings analysed individually and collectively where possible. Twenty RCTs were included (an additional 14 to an earlier systematic review). The population, outcome, and findings were highly heterogeneous. However, meta-analyses were able to be performed with 7 studies,finding in favour of the FM for improving balance in ageing populati…
Natural History of Mesenteric Venous Thrombosis: A Large Multicentre Study
2008
Abstract Introduction: Mesenteric venous thrombosis (MVT) is an uncommon but potentially life-threatening disease, accounting for 5–15% of mesenteric ischemic events. Most cases of MVT are either identified at laparotomy or at autopsy, with a mortality rate of approximately 50% in old series. Advances in imaging techniques have facilitated the early diagnosis of MVT and, thus, have contributed to a decrease in mortality in the more recent series. The treatment of MVT involves anticoagulation alone or in combination with surgery. Experts suggest that MVT can safely be managed without surgery if there is no evidence of bowel infarction. However, information on the natural history of MVT and o…
Decrease of CD4+ T Lymphocytes after myocardial infarction is related with extensive myocardial fibrosis
2013
Purpose: Myocardial fibrosis plays a potential role in left ventricular remodeling and patients' outcome. After myocardial infarction innate immune cells infiltrate infarcted area and replace necrotic tissue by fibrotic tissue. However the role of adaptive immunity, especially T cells, has not yet been investigated in this scenario. Methods: We studied 94 patients with a first STEMI treated with percutaneous revascularization. Leucocyte subsets and a wide variety of lymphocyte subtypes were determined in peripheral blood 24 h after reperfusion by means of flow cytometry. Infarct size and cardiac fibrosis were measured by late enhancement Cardiac Magnetic Resonance (CRM) 1 week and 6 months …
The Role of Cardiac Pacing in Heart Block Complicating Acute Myocardial Infarction
1983
The organization of the Coronary Care Unit and the use of electrocardiographic monitoring have allowed a re-evaluation of the incidence of the atrioventricular conduction disturbances in acute myocardial infarction.
Routine cardiac troponin assessment after percutaneous coronary intervention
2019
: Although the angiographic and procedural success of percutaneous coronary intervention (PCI) is now very high, some severe complications may still develop, including periprocedural myocardial infarction (MI). An accurate diagnosis of this condition is essential for guiding the clinical management, as these patients may need a tailored management. The current recommendations for diagnosing periprocedural myocardial infarction based on the fourth universal definition appear at first sight straightforward, but the clinical and prognostic significance of routine periprocedural cardiac troponin (cTn) assessment remains uncertain. The current scientific evidence suggests that the likelihood of …
Surgical management of moderate ischemic mitral valve regurgitation: Where do we stand?
2014
Ischemic mitral regurgitation (IMR) represents a common complication after myocardial infarction. The valve is anatomically normal and the incompetence is the result of papillary muscles displacement and annular dilatation, causing leaflets tethering. Functionally the leaflets present a restricted systolic motion due to tethering forces that displaces the coaptation surface toward the left ventricle apex. The patients present poor left ventricular function at the time of surgery and the severity of the mitral regurgitation increases the risk of mortality. Currently there is general agreement to treat surgically severe IMR nevertheless strong evidences for patient with moderate insufficiency…
A case of combined Farber and Sandhoff disease
1989
We describe a patient with the biochemically established combination of Farber and Sandhoff disease. A 6-month-old girl of consanguineous Turkish parents presented with hoarseness, stridor, scattered skin nodules, painful swelling of hand joints and ankles, and cherry-red macular spots. Until the age of 2 years her motor and physical condition deteriorated distinctly, however her mental state remained unchanged. A biopsied skin nodule disclosed lysosomal inclusions within storage cells that were typical of Farber disease (curved tubular structures). However, other inclusions (e.g. zebra bodies) were also found. Biochemical findings included ceramide accumulation in skin nodules and cultured…
