Semantic-aware Temporal Channel-wise Attention for Cardiac Function Assessment [PDF]

arXiv, 2023
Cardiac function assessment aims at predicting left ventricular ejection fraction (LVEF) given an echocardiogram video, which requests models to focus on the changes in the left ventricle during the cardiac cycle. How to assess cardiac function accurately and automatically from an echocardiogram video is a valuable topic in intelligent assisted ...

Prognosis of Adults With Borderline Left Ventricular Ejection Fraction [PDF]

JACC: Heart Failure, 2016
This study sought to examine the association of a borderline left ventricular ejection fraction (LVEF) of 50% to 55% with cardiovascular morbidity and mortality in a community-based cohort.Guidelines stipulate a LVEF >55% as normal, but the optimal threshold, if any, remains uncertain.

Lightweight and Interpretable Left Ventricular Ejection Fraction Estimation using Mobile U-Net [PDF]

arXiv, 2023
Accurate LVEF measurement is important in clinical practice as it identifies patients who may be in need of life-prolonging treatments. This paper presents a deep learning based framework to automatically estimate left ventricular ejection fraction from an entire 4-chamber apical echocardiogram video.

SERUM LEVEL OF ADVANCED OXIDATION PROTEIN PRODUCTS AND THE ACTIVITY OF SUPEROXIDE DISMUTASE AS THE MARKERS OF OXIDATIVE STRESS IN PATIENTS WITH CHRONIC HEART FAILURE

Кубанский научный медицинский вестник, 2019
Aim. The present work was aimed at studying and analysing the serum level of advanced oxidation protein products (AOPPs) and the total superoxide dismutase activity (total SOD) in patients with chronic heart failure (CHF) with a preserved and low left ...

The prognostic value of clinical frailty scale and outcomes in older patients undergoing left ventricular assist device implantation

AGING MEDICINE, Volume 5, Issue 4, Page 257-263, December 2022., 2022
The main finding in our study is that Clinical Frailty Scale‐defined frailty status was predictive of 1‐year post‐interventional mortality after left ventricular assist device implantation. Abstract Objectives Heart failure impacts patients’ functional capabilities, ultimately leading to frailty.

Expression of epicardial adipose tissue thermogenic genes in patients with reduced and preserved ejection fraction heart failure [PDF]

, 2017
[Abstract] Epicardial adipose tissue has been proposed to participate in the pathogenesis of heart failure. The aim of our study was to assess the expression of thermogenic genes (Uncoupling protein 1 (UCP1), peroxisome proliferator-activated receptor ...

Lovo‐cel gene therapy for sickle cell disease: Treatment process evolution and outcomes in the initial groups of the HGB‐206 study

American Journal of Hematology, Volume 98, Issue 1, Page 11-22, January 2023., 2023
Treatment process evolution. *The target TNC for BMH was ≥6 × 108/kg per patient. The Group B1 patient received lovo‐cel produced using both the original and refined manufacturing process, and the Group B2 patient received lovo‐cel produced using only the refined manufacturing process.

Autonomic regulation therapy to enhance myocardial function in heart failure patients: the ANTHEM-HFpEF study. [PDF]

, 2017
BackgroundApproximately half of the patients presenting with new-onset heart failure (HF) have HF with preserved left ventricular ejection fraction (HFpEF) and HF with mid-range left ventricular ejection fraction (HFmrEF).

A rare homozygous missense GDF2 (BMP9) mutation causing PAH in siblings: Does BMP10 status contribute?

American Journal of Medical Genetics Part A, Volume 191, Issue 1, Page 228-233, January 2023., 2023
Abstract Pulmonary arterial hypertension (PAH) is a disease characterized by pathological remodeling of the pulmonary vasculature causing elevated pulmonary artery pressures and ultimately, right ventricular failure from chronic pressure overload. Heterozygous pathogenic GDF2 (encoding bone morphogenetic protein 9 (BMP9)) variants account for some (>1%)

Progressive induction of left ventricular pressure overload in a large animal model elicits myocardial remodeling and a unique matrix signature [PDF]

, 2012
ObjectivePatients with severe left ventricular pressure overload secondary to aortic stenosis can present with signs and symptoms of heart failure despite normal left ventricular ejection fraction.
