Abstract:

Ejection fraction (EF) is an important indicator of cardiac function, especially in clinical conditions. Unlike imaging technology such as echocardiography, impedance cardiography (ICG) is a low-cost, non-invasive and continuous method of monitoring EF. However, the accuracy of the ICG method to evaluate the EF value needs to be further improved. This paper uses a simplified ventricular model to simplify the complex relationship between the EF value and the relevant ICG parameters, and proposes a method for calculating the EF value through these relevant ICG parameters. We tested this method w

Abstract:

Ventricular volumetric ejection fraction (VV EF) is often normal in patients with single ventricle circulations despite them experiencing symptoms related to circulatory failure. We sought to determine if kinetic energy (KE) could be a better marker of ventricular performance. KE was prospectively quantified using four-dimensional flow MRI in 41 patients with a single ventricle circulation (aged 0.5–28 yr) and compared with 43 healthy volunteers (aged 1.5–62 yr) and 14 patients with left ventricular (LV) dysfunction (aged 28–79 yr).

Abstract:

The newly defined category of heart failure (HF) with mid-range ejection fraction (HFmrEF; EF 40–49 %) is beginning to be characterised but little is known about the potential for treating it. Trials and observational studies suggest that standard therapy for HF with reduced ejection fraction (HFrEF; EF <40 %) may also offer some benefit to patients with EF ≥40 %; however, any difference between its effects on HFmrEF and true HF with preserved ejection fraction (HFpEF) have until now not been explored.

Abstract:

Ejection fraction (EF) is the percentage of the difference between the end-diastolic volume and the end-systolic volume divided by the end-diastolic volume. This measurement is important in determining how well the heart is pumping out blood and in diagnosing heart failure (HF). Normally the percentage of EF is above 50%. A decrease in EF will make it difficult to perform anesthesia during surgery due to life-threatening irregular heartbeats, leading to sudden cardiac arrest and sudden death.

While both types share several risk factors and features of adverse cardiac remodeling, unique hallmarks beyond ejection fraction that distinguish these etiologies also exist.

As an alternative, the ESV–EDV graph is advocated. This study identifies the dependence of the EF and the EDV–ESV graph on the major determinants of ventricular performance.

Abstract:

BACKGROUND: Exercise-induced cardiac remodeling can be profound, resulting in clinical overlap with dilated cardiomyopathy, yet the significance of reduced ejection fraction (EF) in athletes is unclear. The aim is to assess the prevalence, clinical consequences, and genetic predisposition of reduced EF in athletes. METHODS: Young endurance athletes were recruited from elite training programs and underwent comprehensive cardiac phenotyping and genetic testing. Those with reduced EF using cardiac magnetic resonance imaging (defined as left ventricular EF <50%, or right ventricular EF <45%,

Introduction: The incidence of patients posted for coronary artery bypass graft (CABG) with low ejection fraction (EF) is on the rise. These patients present a challenge for the attending anesthesiologist in the perioperative period as they have a poor tolerance to the stress of anesthesia as well as surgery. Maintaining forward flow with avoidance of arrhythmias and hypotension is the primary goals of balanced anesthesia.

Abstract:

Heart failure, a leading global cause of death, poses challenges for early prediction of cardiac dysfunction, especially ejection fraction (EF). This study employs Convolutional Neural Networks (CNNs), utilizing ResNet and MobileNet architectures, on the CAMUS dataset with 500 patient records (2CH and 4CH). The goal is to aid healthcare professionals in accurately measuring EF. The CAMUS dataset, comprising multi-modality cardiac imaging and segmentation data, serves as the foundation. The CNN, ResNet, and MobileNet models are fine-tuned through transfer learning and their performance is evalu

Background: Heart failure with improved ejection fraction (HFimpEF) is defined by prior HF with reduced EF (HFrEF) and evidence of systolic improvement and is associated with improved outcomes. Despite this, HFimpEF patients remain at risk of future adverse events, including EF decline. However, little is known about factors associated with EF trajectory in this population. Question: Are baseline clinical characteristics associated with future EF decline in HFimpEF?

Abstract:

Heart failure (HF) remains a major problem in the modern healthcare system, which is a significant cause of hospitalizations, disability and mortality among the population. Left ventricular (LV) ejection fraction (EF) remains one of the main criteria for distribution HF patients into groups and on which the tactics of observation and treatment depend. The European Society of Cardiology distinguishes HF with preserved EF, HF with mid‑range EF, and HF with a reduced EF. Recently, to assess the risks, scientists have divided patients with HF into the following phenotypes according to the left ven

Abstract:

Hypothesis: Venous occlusion impairs cardiac ventricle filling to end-diastolic volume (EDV). As EDV preload is reduced, ejected stroke volume (SV) is simultaneously lowered. The EDV mediation of SV output reflects the Frank-Starling Mechanism and compels a presented hypothesis that ejection fraction ratio EF=SV/EDV might remain constant during preload adjustment. Methods: Pressure volume (PV) loop datasets (n=34) recorded from female swine left ventricles 1 were provided for studied post-processing. Each dataset was analyzed to compute EF in the natural steady-state. Following EF measurement,
