P852Frequency and prognosis of type 2 myocardial infarction vs non ischemic myocardial injury: large observational study from an emergency department
2019
Abstract Background Type 2 Myocardial Infarction (T2MI), due to myocardial oxygen supply-demand mismatch in the absence of atherothrombosis and non-ischemic myocardial injury (NIMI), corresponding to troponin elevation without overt ischemia, are emerging concepts which are suspected to be common in patients hospitalized. However, their respective frequencies, risk profiles and short term prognosis in current routine clinical practice of emergency unit remains to be investigated. Methods Among the medical records of all the patients admitted from January 2014 to December 2016 in a university hospital emergency unit (n=82 543), patients with elevated troponin Ic (≥0.10μg/L) (n=4568) were sys…

Temporal Profile of Gene Induction After Venous Ischemia and Effects of Spreading Depression
2004
Occlusion of two adjacent cortical veins is followed by a widespread reduction of rCBF and the occurrence of small infarcts, which become larger if spreading depression (SD) occurs. The infarct matures over time with TUNEL-positive cells seen in the penumbra up to 4 days after vein occlusion. Caspase inhibition with zVAD.fmk reduces infarct size. Here, the time course of gene expression in the penumbra is compared to that induced by SD alone.
Orthostatic Hypotension and Complications
2020
Orthostatic hypotension prevalence exponentially increases with age, and an early detection of it can prevent the severe complications it may lead to. Among those, we mention (orthostatic) syncope and falls, cardiovascular diseases, and neurological diseases. Increased blood pressure variability related to standing which can provoke brain hypoperfusion and ischemia, higher arterial stiffness, and activated systematic inflammation, which have both been strongly involved in the pathogenesis of atherosclerosis, finally leading to CVD.
Evaluation of postoperative myocardial injury by heart-type fatty acid-binding protein in off-pump coronary artery bypass grafting surgery
2015
Abstract Background and goal of study Postoperative myocardial infarction is a serious and frequent complication of cardiac surgery. Nonetheless, diagnosis in this context is occasionally challenging. We sought to evaluate the kinetics and diagnostic accuracy of the new biomarker “heart-type fatty acid-binding protein” (h-FABP) in the early detection of myocardial injury in patients undergoing off-pump coronary artery bypass grafting, compared with classical biomarkers. Materials and methods A prospective study was conducted on 17 consecutive patients who underwent off-pump coronary artery bypass grafting during a 2-month period. Blood samples were drawn for measurement of myocardial ischem…

Time-frequency analysis for early classification of persistent and long-standing persistent atrial fibrillation
2016
This study aimed to assess an early classification of persistent and long-standing persistent atrial fibrillation patients by means of the time-frequency analysis of the surface ECG, which would allow electrophysiologists to choose the most suitable therapeutic approach to treat this arrhythmia. 140 consecutive unselected patients suffering from atrial fibrillation conformed the study population (84 persistent and 56 long-standing persistent). After ventricular activity cancellation, time-frequency analysis of the atrial activity was performed. Then, the study of phase variations along time for those frequency bands where the average power of atrial activity is concentrated, together with t…
Endovascular Treatment of Giant Visceral Aneurysms: An Overview
2021
Giant visceral aneurysms (or pseudoaneurysms) are aneurysmal lesions of the splanchnic vessels that are larger than 5 cm in diameter. As with other visceral aneurysms, treatment may be either surgical or endovascular. Both treatments face challenges given the anatomical complexity of such lesions. However, in the era of novel tools and techniques that have been developed in this field, an increasing number of giant visceral aneurysms can now be treated using endovascular approaches. The purpose of this article is to offer an overview of the most current techniques and trends in the endovascular treatment of giant visceral artery aneurysms.
