Estimation of Left and Right Ventricular Ejection Fractions from cine-MRI Using 3D-CNN

Sensors, 2023
Cardiac function indices must be calculated using tracing from short-axis images in cine-MRI. A 3D-CNN (convolutional neural network) that adds time series information to images can estimate cardiac function indices without tracing using images with ...

Echocardiographic Features of Patients With Heart Failure and Preserved Left Ventricular Ejection Fraction.

Journal of the American College of Cardiology, 2019
BACKGROUND The PARAGON-HF (Prospective Comparison of ARNI With ARB Global Outcomes in HF With Preserved Ejection Fraction) trial tested the efficacy of sacubitril-valsartan in patients with heart failure with preserved ejection fraction (HFpEF). Existing

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 ...

Coronary Artery Disease and Heart Failure With Preserved Ejection Fraction: The ARIC Study

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2022
Background Whether coronary artery disease (CAD) is a significant risk factor for heart failure (HF) with preserved ejection fraction (HFpEF) is unclear. Methods and Results Among 9902 participants in the ARIC (Atherosclerosis Risk in Communities) study,

Early assessment of percutaneous coronary interventions for chronic total occlusions analyzed by novel echocardiographic techniques

Clinics, 2013
OBJECTIVE: Successful revascularization of chronic total occlusions has been associated with improved left ventricular systolic function, reduced anginal symptoms, increased exercise capacity, and increased survival. This study was conducted to determine

Association of Left Ventricular Ejection Fraction and Symptoms With Mortality After Elective Noncardiac Surgery Among Patients With Heart Failure

Journal of the American Medical Association (JAMA), 2019
Importance Heart failure is an established risk factor for postoperative mortality, but how left ventricular ejection fraction and heart failure symptoms affect surgical outcomes is not fully described.

Heart Failure With Normal Left Ventricular Ejection Fraction

Journal of the American College of Cardiology, 2009
It is estimated that approximately 50% of the heart failure population has a normal left ventricular ejection fraction, a complex broadly referred to as heart failure with normal left ventricular ejection fraction (HFNEF). While these patients have been considered in epidemiologic studies and clinical trials to represent a single pool of patients ...

A Personalized, 3D Printed Polymeric Device for the Prevention of Post‐Myocardial Infarction Cardiac Remodeling

Advanced Healthcare Materials, EarlyView.
Myocardial infarction often leads to pathological remodelling and ventricular dilatation, key features of HFrEF. This study introduces a personalized, 3D‐printed cardiac restraint device (CARD) printed using rationally designed inks displaying the requested printability and mechanical properties.

Dynamic Trajectories of Left Ventricular Ejection Fraction in Heart Failure.

Journal of the American College of Cardiology, 2018
BACKGROUND Long-term trajectories of left ventricular ejection fraction (LVEF) in heart failure (HF) are incompletely characterized. OBJECTIVES This study sought to examine LVEF trajectories in HF with reduced LVEF (

Extracellular Vesicles Modulation by an Adiponectin Receptor Agonist Provides Cardioprotection for Myocardial Ischemic Injury

Advanced Healthcare Materials, EarlyView.
This study demonstrates that ALY688, a drug mimicking the heart‐protective hormone adiponectin, reduces myocardial ischemia injury. ALY688 increases the production of extracellular vesicles, which carry protective cargo including adiponectin itself.
