Pulmonary fat embolism of neoplastic origin
ABSTRACT Obstructive sleep apnea (OSA) is a common clinical condition, with a variable and underestimated prevalence. OSA is the main condition associated with secondary systemic arterial hypertension, as well as with atrial fibrillation, stroke, and coronary artery disease, greatly increasing cardiovascular morbidity and mortality. Treatment with continuous positive airway pressure is not tolerated by all OSA patients and is often not suitable in cases of mild OSA. Hence, alternative methods to treat OSA and its cardiovascular consequences are needed. In OSA patients, regular physical exercise has beneficial effects other...

Cardiologs wins FDA 510(k) for ECG analysis platform
Cardiologs Technologies said today it won FDA 510(k) clearance for its Cardiologs ECG analysis platform designed to aid in the screening for atrial fibrillation and other arrhythmias. The platform is a cloud-based cardiac monitoring and analysis web service which uses artificial intelligence to analyze long-term ambulatory ECG monitoring recordings, the Paris-based company said. The system already has CE Mark approval in the European Union, the company added. “It is intuitive that screening for AFib and subsequent anticoagulant treatment should reduce the stroke burden, which is the basis of guideline recommendations...

The Benefits of Exercise Training on Aerobic Capacity in Patients with Heart Failure and Preserved Ejection Fraction.
Authors: do Prado DML, Rocco EA Abstract Heart failure with preserved ejection fraction (HFpEF) is defined as an inability of the ventricles to optimally accept blood from atria with blunted end- diastolic volume response by limiting the stroke volume and cardiac output. The HEpEF prevalence is higher in elderly and women and may be associated to hypertension, diabetes mellitus and atrial fibrillation. Severe exercise intolerance, manifested by dyspnea and fatigue during physical effort is the important chronic symptom in HFpEF patients, in which is the major determinant of their reduced quality of life. In this se...

The impact of lifestyle intervention on atrial fibrillation
Purpose of review Atrial fibrillation is the most common sustained cardiac arrhythmia, attributable to several factors that may be amenable through lifestyle modification. There is emerging evidence to suggest that the successful management of several cardiovascular risk factors [obesity, hypertension (HTN), diabetes mellitus, and obstructive sleep apnea (OSA)] can lead to fewer complications and atrial fibrillation prevention. However, the long-term sustainability and reproducibility of these effects have yet to be explored in larger studies. This review explores recent findings for exercise and lifestyle modifications ...

Role of cardiac imaging and three-dimensional printing in percutaneous appendage closure.
Abstract Atrial fibrillation is the most frequent cardiac arrhythmia, affecting up to 13% of people aged>80 years, and is responsible for 15-20% of all ischaemic strokes. Left atrial appendage occlusion devices have been developed as an alternative approach to reduce the risk of stroke in patients for whom oral anticoagulation is contraindicated. The procedure can be technically demanding, and obtaining a complete left atrial appendage occlusion can be challenging. These observations have emphasized the importance of preprocedural planning, to optimize the accuracy and safety of the procedure. In this setting, ...

HRS: Ear Clip Uses Neurostimulation to Effectively Reduce AFib Burden
A trial evaluating Parasym’s neurostimulation technology shows the ear-clip like device can help reduce the atrial fibrillation burden. The results were presented at the Heart Rhythm Society’s 40th Annual Scientific Sessions held in San Francisco. The TREAT AF trial is a sham-controlled, double-blind, randomized clinical trial designed to examine the effect of low-level transcutaneous electrical stimulation of the auricular branch of the vagus nerve at the tragus (LLTS) on AFib burden over a six-month period. LLTS was delivered using an ear clip attached to either tragus (active; n=26) o...

An artificial intelligence-enabled ECG algorithm for the identification of patients with atrial fibrillation during sinus rhythm: a retrospective analysis of outcome prediction
Publication date: Available online 1 August 2019Source: The LancetAuthor(s): Zachi I Attia, Peter A Noseworthy, Francisco Lopez-Jimenez, Samuel J Asirvatham, Abhishek J Deshmukh, Bernard J Gersh, Rickey E Carter, Xiaoxi Yao, Alejandro A Rabinstein, Brad J Erickson, Suraj Kapa, Paul A FriedmanSummaryBackgroundAtrial fibrillation is frequently asymptomatic and thus underdetected but is associated with stroke, heart failure, and death. Existing screening methods require prolonged monitoring and are limited by cost and low yield. We aimed to develop a rapid, inexpensive, point-of-care means of identifying patients with atrial ...

Monitoring of atrial fibrillation in primary care patients prescribed direct oral anticoagulants for stroke prevention
ConclusionsResults show that there was incomplete adherence to the 2013 EHRA prescribing guidelines with only 24% adhering to all seven guidelines, and patient follow-up was less frequent than has been suggested.

Sensors, Vol. 20, Pages 765: Detection of Atrial Fibrillation Episodes in Long-Term Heart Rhythm Signals Using a Support Vector Machine
Jezewski Leski Atrial fibrillation (AF) is a serious heart arrhythmia leading to a significant increase of the risk for occurrence of ischemic stroke. Clinically, the AF episode is recognized in an electrocardiogram. However, detection of asymptomatic AF, which requires a long-term monitoring, is more efficient when based on irregularity of beat-to-beat intervals estimated by the heart rate (HR) features. Automated classification of heartbeats into AF and non-AF by means of the Lagrangian Support Vector Machine has been proposed. The classifier input vector consisted of sixteen features, including four coefficien...

Sensors, Vol. 20, Pages 2136: Detection of Atrial Fibrillation Using 1D Convolutional Neural Network
a Hsiao The automatic detection of atrial fibrillation (AF) is crucial for its association with the risk of embolic stroke. Most of the existing AF detection methods usually convert 1D time-series electrocardiogram (ECG) signal into 2D spectrogram to train a complex AF detection system, which results in heavy training computation and high implementation cost. This paper proposes an AF detection method based on an end-to-end 1D convolutional neural network (CNN) architecture to raise the detection accuracy and reduce network complexity. By investigating the impact of major components of a convolutional block on detectio...
