Dynamic trajectories of left ventricular ejection fraction in heart failure with improved ejection fraction [PDF]

BMC Cardiovascular Disorders
BACKGROUND: Heart failure with improved ejection fraction (HFimpEF) has been regarded as a new heart failure (HF) type in 2022. However, studies on the impact of left ventricular ejection fraction (LVEF) trajectories on the prognosis of patients with HFimpEF are scarce.

Hierarchical Vision Transformers for Cardiac Ejection Fraction Estimation [PDF]

IWBIS 2022 International Workshop on Big Data and Information Security (IWBIS) 2022, 2023
The left ventricular of ejection fraction is one of the most important metric of cardiac function. It is used by cardiologist to identify patients who are eligible for lifeprolonging therapies. However, the assessment of ejection fraction suffers from inter-observer variability.

One-year outcomes after transcatheter insertion of an interatrial shunt device for the management of heart failure with preserved ejection fraction [PDF]

, 2016
Background—Heart failure with preserved ejection fraction has a complex pathophysiology and remains a therapeutic challenge. Elevated left atrial pressure, particularly during exercise, is a key contributor to morbidity and mortality.

Therapeutic Stalemate in Heart Failure With Preserved Ejection Fraction

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2021
The findings of randomized trials of neurohormonal modulation have been neutral in heart failure with preserved ejection fraction and consistently positive in heart failure with reduced ejection.

Left Ventricular Remodeling Shortly after Open Mitral Valve Replacement for Rheumatic Mitral Stenosis

Brazilian Journal of Cardiovascular Surgery, 2021
Introduction: Left ventricular dysfunction after surgical treatment of mitral stenosis is uncommon. We intend to determine the pattern of left ventricular remodeling, shortly after open mitral valve replacement for rheumatic mitral stenosis, with in ...

Left Ventricular Volumes and Ejection Fraction by Echocardiography [PDF]

Circulation, 1971
Left ventricular end-diastolic and end-systolic volume, stroke volume, and ejection fraction were determined by biplane angiocardiography and echocardiography in 27 patients suspected of having heart disease. Angiographic volumes were calculated by the area-length method and echocardiographic volumes, from the left ventricular dimension of

Factors influencing left ventricular ejection fraction in patients with coronary microvascular disease and obstructive coronary artery disease

BMC Research Notes, 2020
Objective The aim of our research was to evaluate the relationship involving left ventricular ejection fraction, low density lipoprotein, B-type natriuretic peptide, Troponin I and coronary flow reserve, and to determine the predictors of left ...

Heart Failure With Midrange Ejection Fraction: Prior Left Ventricular Ejection Fraction and Prognosis [PDF]

Frontiers in Cardiovascular Medicine, 2021
Aims: Evidence-based guidelines for heart failure management depend mainly on current left ventricular ejection fraction (LVEF). However, fewer studies have examined the impact of prior LVEF. Patients may enter the heart failure with midrange ejection fraction (HFmrEF) category when heart failure with preserved ejection fraction (HFpEF) deteriorates or

Relation between three-dimensional and two-dimensional echocardiography and biochemical analysis in patients with ST-segment elevation myocardial infarction percutaneously treated [PDF]

Einstein (São Paulo), 2010
Objective: The prognosis of patients with acute myocardial infarction depends on multiple features that can demonstrate myocardial injury degree (such as serum markers of cardiac necrosis), and also on adaptive mechanisms relative to the acute event. The

Association of Left Ventricular Ejection Fraction with Mortality and Hospitalizations [PDF]

Journal of the American Society of Echocardiography, 2020
Although echocardiography is widely used to measure left ventricular ejection fraction (LVEF), its prognostic value has not been demonstrated in a broad range of patients including those acutely hospitalized for cardiac or noncardiac causes.
