Large-Scale Candidate Gene Analysis in Whites and African Americans Identifies IL6R Polymorphism in Relation to Atrial Fibrillation The National Hear…

2011

Background— The genetic background of atrial fibrillation (AF) in whites and African Americans is largely unknown. Genes in cardiovascular pathways have not been systematically investigated. Methods and Results— We examined a panel of approximately 50 000 common single-nucleotide polymorphisms (SNPs) in 2095 cardiovascular candidate genes and AF in 3 cohorts with participants of European (n=18 524; 2260 cases) or African American descent (n=3662; 263 cases) in the National Heart, Lung, and Blood Institute's Candidate Gene Association Resource. Results in whites were followed up in the German Competence Network for AF (n=906, 468 cases). The top result was assessed in relation to incident i…

Amulet or Watchman Device for Percutaneous Left Atrial Appendage Closure: Primary Results of the SWISS-APERO Randomized Clinical Trial.

2022

Background:No study has so far compared Amulet with the new Watchman FLX in terms of residual left atrial appendage (LAA) patency or clinical outcomes in patients undergoing percutaneous LAA closure.Methods:In the investigator-initiated SWISS APERO trial (Comparison of Amulet Versus Watchman/FLX Device in Patients Undergoing Left Atrial Appendage Closure), patients undergoing LAA closure were randomly assigned (1:1) open label to receive Amulet or Watchman 2.5 or FLX (Watchman) across 8 European centers. The primary end point was the composite of justified crossover to a nonrandomized device during LAA closure procedure or residual LAA patency detected by cardiac computed tomography angiogr…

Cancer Patients Requiring Interruption of Long-Term Anticoagulant Therapy: The Use of Fixed Sub-Therapeutic Doses of Low-Molecular Weight Heparin

2011

Abstract Abstract 1244 Introduction. We tested the efficacy and safety of fixed doses of Low-Molecular Weight Heparin (LMWH) in cancer patients requiring interruption of Vitamin-k Antagonist (VKA) because of invasive procedures (defined as major and non major surgery) or chemotherapy inducing platelets depletion. Methodology. Cancer patients were defined to be at high (atrial fibrillation [AF] with previous stroke, prosthetic mitralic valves and venous thromboembolism [VTE] lasting < 3months) or low risk of thrombosis (AF without previous stroke, VTE lasted > 3 months, and prosthetic aortic valves). They discontinued VKA 5 + 1days before surgery or chemotherapy; in those at low-risk f…

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…

A Multi-Variate Predictability Framework to Assess Invasive Cardiac Activity and Interactions during Atrial Fibrillation

2017

Objective: This study introduces a predictability framework based on the concept of Granger causality (GC), in order to analyze the activity and interactions between different intracardiac sites during atrial fibrillation (AF). Methods: GC-based interactions were studied using a three-electrode analysis scheme with multi-variate autoregressive models of the involved preprocessed intracardiac signals. The method was evaluated in different scenarios covering simulations of complex atrial activity as well as endocardial signals acquired from patients. Results: The results illustrate the ability of the method to determine atrial rhythm complexity and to track and map propagation during AF. Conc…

0057 : Preoperative Growth Differentiation Factor 15 (GDF15) as a novel biomarker of acute kidney injury after cardiac bypass surgery

2015

ObjectivePreviously, we demonstrated that preoperative plasma GDF15 levels significantly improved the prognostic value of the EuroSCORE for mortality after cardiac surgery. Despite the strong correlation between GDF15 and renal function, no data are available regarding the potential interest of preoperative GDF15 levels to improve the prediction of acute kidney injury (AKI) after coronary artery bypass grafting (CABG).Design134 patients operated on for CABG of whom 50 underwent offpump surgery at our university hospital were included in this prospective, observational study. Exclusion criteria were age 80 years, previous atrial fibrillation/flutter, previous severe renal failure (estimated …

Global public awareness about atrial fibrillation

2017

Essentials Early recognition of atrial fibrillation helps in stroke prevention. Survey in 10 countries to assess public awareness of atrial fibrillation. Overall global awareness of atrial fibrillation was 48%. Less than 46% of participants were aware atrial fibrillation leads to stroke. Background Atrial fibrillation (AF) is an important cause of ischemic stroke that often remains undetected until stroke occurs. Awareness of the risk factors and symptoms is important so that AF can be diagnosed and thromboprophylaxis given. However, the extent of public awareness of AF is uncertain. We assessed public awareness of AF across six continents and compared it with that of other thrombotic and n…

Introduction and objective. Atrial fibrillation is the most common arrhythmia seen in clinical practice. The objective of this study was to know the frequency of atrial fibrillation and the characteristics of patients with atrial fibrillation in the Cardiotens study. Material and method. A cross-section study with systematic selection of the study sample. All 32,051 outpatients seen on the same day by 1,159 physicians specialized in primary-care (79%) and cardiology (21%) were prospectively added to a database including history of cardiac disease (heart failure, coronary disease or atrial fibrillation), blood pressure, and ongoing treatment. Results. Atrial fibrillation was present in 25% o…

Digoxin-related leukocytoclastic vasculitis in a very elderly woman: A case report

2016

International audience; Even though digoxin causes many side effects, few cases of skin involvement are recorded in the French Pharmacovigilance Database. We report a case of leukocytoclastic vasculitis (LV) very probably due to digoxin. A 91-year-old woman, hospitalized following a fall, presented cardiac decompensation in a context of rapid atrial fibrillation requiring treatment with digoxin. Eight days later, a rash appeared on her back and trunk. It was neither itchy, nor painful and persisted despite local treatment. There were no other clinical anomalies. After a few days, the rash spread with appearance of bullous lesions, ulcerations and a necrosis on lymphedema of the two legs. Am…
