Heart failure (HF) is a clinical syndrome defined by specific symptoms and signs due to
structural and/or functional heart abnormalities, which lead to inadequate cardiac output …

Left ventricular ejection fraction (LVEF) is universally accepted as a cardiac systolic function
index and it provides intuitive interpretation of cardiac performance. Over the last two …

Background Assessment of cardiac output (CO) and stroke volume (SV) is essential to
understand cardiac function and hemodynamics. These parameters can be examined using …

Background Sacubitril/valsartan improves outcome in patients with heart failure (HF) with
reduced left ventricular (LV) ejection fraction (EF, HFrEF). However, little is known about …

Heart failure (HF) is a progressive condition with a clinical picture resulting from reduced
cardiac output (CO) and/or elevated left ventricular (LV) filling pressures (LVFP). The original …

Background Left ventricular (LV) output is a predictor of adverse outcome in patients with
heart failure. It can be evaluated using a per-beat approach, measuring stroke volume index …

Background: Although in clinical practice heart failure (HF) patients are classified using left
ventricular ejection fraction (LVEF), this categorization is insufficient for prognosis, especially …

Heart failure (HF) with preserved ejection fraction (HFpEF) is a heterogeneous syndrome
including several morphological phenotypes and varying pathophysiological mechanisms …

Background: Most of the factors and prediction models of sudden cardiac death (SCD) have
been developed without considering the Asia population. The purpose of this study is to …

Background In a significant proportion of patients with left-sided heart failure (HF), left
ventricular filling pressure (LVFP) may not be estimated using echocardiography, so filling …
