Adaptive Contrast for Image Regression in Computer-Aided Disease Assessment [PDF]

arXiv, 2021
Image regression tasks for medical applications, such as bone mineral density (BMD) estimation and left-ventricular ejection fraction (LVEF) prediction, play an important role in computer-aided disease assessment. Most deep regression methods train the neural network with a single regression loss function like MSE or L1 loss.

Left ventricular systolic function evaluated by strain echocardiography and relationship with mortality in patients with severe sepsis or septic shock. a systematic review and meta-analysis [PDF]

, 2018
Sepsis-induced myocardial dysfunction is associated with poor outcomes, but traditional measurements of systolic function such as left ventricular ejection fraction (LVEF) do not directly correlate with prognosis.

Can NT-proBNP Levels Be an Early Biomarker of Reduced Left Ventricular Ejection Fraction in Preterm Infants?

Children, 2022
Background/Objective: N-terminal pro-B-type natriuretic peptide (NT-proBNP) is a cardiac natriuretic hormone that cardiomyocytes release in response to ventricular stretch.

EchoCoTr: Estimation of the Left Ventricular Ejection Fraction from Spatiotemporal Echocardiography [PDF]

arXiv, 2022
Learning spatiotemporal features is an important task for efficient video understanding especially in medical images such as echocardiograms. Convolutional neural networks (CNNs) and more recent vision transformers (ViTs) are the most commonly used methods with limitations per each.

Light-weight spatio-temporal graphs for segmentation and ejection fraction prediction in cardiac ultrasound [PDF]

arXiv, 2022
Accurate and consistent predictions of echocardiography parameters are important for cardiovascular diagnosis and treatment. In particular, segmentations of the left ventricle can be used to derive ventricular volume, ejection fraction (EF) and other relevant measurements. In this paper we propose a new automated method called EchoGraphs for predicting

Third Trimester Fetal Cardiac Blood Flow and Cardiac Outcomes in School‐Age Children Assessed By Magnetic Resonance Imaging

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2019
Background An adverse fetal environment leads to fetal hemodynamic adaptations with cardiac flow alterations that may subsequently affect cardiac development.

Ultrasound Video Transformers for Cardiac Ejection Fraction Estimation [PDF]

arXiv, 2021
Cardiac ultrasound imaging is used to diagnose various heart diseases. Common analysis pipelines involve manual processing of the video frames by expert clinicians. This suffers from intra- and inter-observer variability. We propose a novel approach to ultrasound video analysis using a transformer architecture based on a Residual Auto-Encoder Network ...

Rate Control Management of Atrial Fibrillation: May a Mathematical Model Suggest an Ideal Heart Rate? [PDF]

PLoS ONE 10(3): e0119868, 2015, 2015
Background. Despite the routine prescription of rate control therapy for atrial fibrillation (AF), clinical evidence demonstrating a heart rate target is lacking. Aim of the present study was to run a mathematical model simulating AF episodes with a different heart rate (HR) to predict hemodynamic parameters for each situation. Methods.

Evaluation of factors associated with selection for coronary angiography and in‐hospital mortality among patients presenting with out‐of‐hospital cardiac arrest without ST‐segment elevation

Catheterization and Cardiovascular Interventions, Volume 100, Issue 7, Page 1159-1170, December 1, 2022., 2022
Abstract Background Clinical factors favouring coronary angiography (CA) selection and variables associated with in‐hospital mortality among patients presenting with out‐of‐hospital cardiac arrest (OHCA) without ST‐segment elevation (STE) remain unclear.
