Right ventricular volumes and function in thalassemia major patients in the absence of myocardial iron overload [PDF]

, 2010
Aim: We aimed to define reference ranges for right ventricular (RV) volumes, ejection fraction (EF) in thalassemia major patients (TM) without myocardial iron overload.Methods and results: RV volumes, EF and mass were measured in 80 TM patients who had ...

Left ventricular ejection fraction is determined by both global myocardial strain and wall thickness

International Journal of Cardiology: Heart & Vasculature, 2015
Objectives: The purpose of this study was to determine the mathematical relationship between left ventricular ejection fraction and global myocardial strain. A reduction in myocardial strain would be expected to cause a fall in ejection fraction. However,

Plasma levels of free fatty acid differ in patients with left ventricular preserved, mid-range, and reduced ejection fraction

BMC Cardiovascular Disorders, 2018
Background Free fatty acids (FFAs) predicted the risk of heart failure (HF) and were elevated in HF with very low left ventricular ejection fraction (LVEF) compared to healthy subjects. The aim of this study was to investigate whether total levels of FFA

The DNA Ejection Process in Bacteriophage λ [PDF]

, 2007
Bacteriophages have long served as model systems through which the nature of life may be explored. From a physical or mechanical point of view, phages are excellent examples of natural nanotechnology: they are nanometer-scale systems which depend ...

Ejection Fraction. [PDF]

, 2016
Echocardiography was used to obtain levels of ejection fraction for pVEGF injection only, sham and pVEGF +GET groups. A) Ejection fraction levels before MI, after the left anterior descending artery (LAD) was occluded and 14 days post MI.

Obesity, Preserved Ejection Fraction Heart Failure, and Left Ventricular Remodeling [PDF]

, 2023
Owing to the overwhelming obesity epidemic, preserved ejection fraction heart failure commonly ensues in patients with severe obesity and the obese phenotype of preserved ejection fraction heart failure is now commonplace in clinical practice.

Comparing the Diagnostic Performance of HFA-PEFF and H2FPEF Scoring Systems in Heart Failure with Preserved Ejection Fraction Patients: Insights from the APOLLON Registry

Anatolian Journal of Cardiology, 2023
Background: Heart failure with preserved ejection fraction is a complex and heterogeneous clinical syndrome, poses significant diagnostic challenges.

Combination of SVI/S′ and diagnostic scores for heart failure with preserved ejection fraction [PDF]

, 2023
The diagnosis of heart failure with preserved ejection fraction (HFpEF) remains a challenge. There are three methods proposed as diagnostic tools. H2FPEF score was determined by six weighted clinical characteristics and echocardiographic variables. Heart

Phenotyping Heart Failure According to the Longitudinal Ejection Fraction Change: Myocardial Strain, Predictors, and Outcomes

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2020
Background Many patients with heart failure (HF) experience changes in left ventricular ejection fraction (LVEF) during follow‐up. We sought to evaluate the predictors and outcomes of different HF phenotypes according to longitudinal changes in EF ...
