Left Atrial Remodeling and Brain Natriuretic Peptide Levels Variation after Left Atrial Appendage Occlusion
2021
Background: Few data are available about brain natriuretic peptide (BNP) variation and left atrial remodeling after the left atrial appendage occlusion (LAAO) technique. Methods: Prospective study included all consecutive patients successfully implanted with an LAAO device. Contrast-enhanced cardiac computed tomography (CT) was performed before and 6 weeks after the procedure with reverse left atrial remodeling defined by an increase in LA volume >
Incremental predictive value of mean platelet volume/platelet count ratio in in-hospital stroke after acute myocardial infarction.
2017
IF 2.558; International audience; Stroke is a serious complication after acute myocardial infarction (AMI) and is associated with an increased risk of death. Though the pathophysiological mechanisms are not exactly known, increased inflammation and platelet reactivity could play an important role in the occurrence of stroke during AMI. We aimed to investigate the relationship between both mean platelet volume (MPV), a parameter of platelet function, and C-reactive protein (CRP) and the occurrence of in-hospital ischemic stroke (IHS) after AMI. Data were obtained from a French regional survey for AMI that included 5976 patients admitted to an intensive care unit (ICU) between 2001 and 2010. …
Detection of Myocardial Infarction by Cardiac Magnetic Resonance in Embolic Stroke Related to First Diagnosed Atrial Fibrillation
2021
Elevated troponin levels are found in a significant number of patients who are diagnosed with acute embolic stroke (AES) after first diagnosed atrial fibrillation (AF). These myocardial injuries, which are known as cardiocerebral infarction (CCI), are potentially caused by coronary embolism and correspond to simultaneous cardiac and cerebral embolisms. However, this severe condition remains poorly understood. In this prospective study, we aimed to investigate the prevalence and the cardiac magnetic resonance (CMR) characteristics of CCI.Consecutive patients with first diagnosed AF hospitalized for AES in a neurovascular intensive care unit from 2019 to 2020 were included. Troponin Ic kineti…
High rate of cardiac thrombus diagnosed by adding cardiac imaging in acute stroke computed tomography protocol
2020
Background Detection of left atrial appendage thrombus (LAAt) in acute stroke patients can be improved by cardiac computed tomography using prospective electrocardiogram-gated volume acquisition, which was added to the acute stroke computed tomography protocol in our institution in 2018. Aims To evaluate the factors and clinical management associated with LAAt in patients with acute ischemic stroke. Methods We retrospectively included 324 consecutive patients with ischemic stroke from November 2018 to October 2019. Clinical data and post-stroke management were compared in LAAt and no-LAAt patients. Results Thirty-five patients (10.8%; 95%CI 7.4–14.2) had LAAt and 289 had no-LAAt. LAAt patie…

Myocardial Infarction Quantification from Late Gadolinium Enhancement MRI Using Top-Hat Transforms and Neural Networks
2019
Significance: Late gadolinium enhanced magnetic resonance imaging (LGE-MRI) is the gold standard technique for myocardial viability assessment. Although the technique accurately reflects the damaged tissue, there is no clinical standard for quantifying myocardial infarction (MI), demanding most algorithms to be expert dependent. Objectives and Methods: In this work a new automatic method for MI quantification from LGE-MRI is proposed. Our novel segmentation approach is devised for accurately detecting not only hyper-enhanced lesions, but also microvascular-obstructed areas. Moreover, it includes a myocardial disease detection step which extends the algorithm for working under healthy scans.…
