Abstract:

The left ventricular ejection fraction (LVEF) is an important clinical indicator of the cardiac function and long-term outcome for patients with coronary artery disease. A biomechanical model of the left ventricle was developed to quantitatively predict post-revascularization LVEF based on noninvasive magnetic resonance imaging. The myocardium was categorized into normal, hibernating, and infarcted regions from the ventricular short-axis images. Assuming that hibernating tissue would potentially regain contractility after revascularization, the expected maximum post-revascularization LVEF was

Abstract:

Echocardiography is one of the imaging systems most often utilized for assessing heart anatomy and function. Left ventricle ejection fraction (LVEF) is an important clinical variable assessed from echocardiography via the measurement of left ventricle (LV) parameters. Significant inter-observer and intra-observer variability is seen when LVEF is quantified by cardiologists using huge echocardiography data. Machine learning algorithms have the capability to analyze such extensive datasets and identify intricate patterns of structure and function of the heart that highly skilled observers might

INTRODUCTION: Peripartum cardiomyopathy (PPCM) incidence varies widely based on maternal health factors such as hypertension and advanced age, race, and access to routine obstetric care.

There is limited understanding of left ventricle ejection fraction (LVEF) recovery rates stratified according to Area Deprivation Index (ADI) residence quartile.

Background and Objectives: Assessment of left ventricle function is the singlemost common indication for transthoracic echocardiogram. Out of different indicators of LVfunction, ejection fraction is the most validated one. MAPSE has promised recently to be a reliableand easily obtainable indicator for LV function even in inexperienced hands but its value in caseof left ventricle hypertrophy (LVH) is questionable.

Abstract: Lower left ventricular ejection fraction (LVEF) is associated with greater mortality among patients with ST-elevation myocardial infarction (STEMI). Renal dysfunction is considered to worsen the prognosis of STEMI patients. This study aimed to determine the correlation between blood urea level and left ventricular ejection fraction in patients with STEMI. This was a descriptive and analytical study using the Spearman’s rho test. Correlation was significant at the 0.05 level.

Abstract:

Abstract Ischemic heart disease is a major causes of heart failure. Heart failure patients have predominantly left ventricular dysfunction (systolic or diastolic dysfunction, or both). Acute heart failure is most commonly caused by reduced myocardial contractility, and increased LV stiffness. We performed echocardiography and gated SPECT with Tc99m MIBI within 263 patients and 166 normal individuals. Left ventricular end systolic volume (LVESV), left ventricular end diastolic volume (LVEDV), and left ventricular ejection fraction (LVEF) were measured. For all degrees of ischemia, there was a s

Abstract:

Left ventricular ejection fraction (LVEF) plays as an essential role in the assessment of cardiac function, providing quantitative data support for the medical diagnosis of heart disease. Robust evaluation of the ejection fraction relies on accurate left ventricular (LV) segmentation of echocardiograms. Because human bias and expensive labor cost exist in manual echocardiographic analysis, computer algorithms of deep-learning have been developed to help human experts in segmentation tasks. Most of the previous work is based on the convolutional neural networks (CNN) structure and has achieved

Cardiac resynchronization therapy (CRT) improves functional classification among patients with left ventricle malfunction and ventricular electric conduction disorders. However, a high percentage of subjects under CRT (20%–30%) do not show any improvement. Nonetheless the presence of mechanical contraction dyssynchrony in ventricles has been proposed as an indicator of CRT response. This work proposes an automated classification model of severity in ventricular contraction dyssynchrony. The model includes clinical data such as left ventricular ejection fraction (LVEF), QRS and P-R intervals, a
