Nearly half of patients with symptoms of heart failure are found to have a normal left
ventricular (LV) ejection fraction. This has variously been labelled as diastolic heart failure …

HFprEF constitutes a heterogenous group of different phenotypes within one continuous
spectrum reflecting heart failure as one disease entity. No pathophysiological basis currently …

Background—Heart failure (HF) can occur in patients with preserved (HFpEF, EF≥ 50%) or
reduced (HFrEF, EF< 50%) ejection fraction (EF), but changes in EF after HF diagnosis are …

Background—Various conventional and tissue Doppler echocardiographic indexes were
compared with pressure–volume loop analysis to assess their accuracy in detecting left …

Background: Conventional transthoracic echocardiography (TTE) and tissue Doppler
imaging (TDI) are usually unable to reveal very early subtle abnormalities in left ventricular …

Background: Although heart failure with a preserved or normal ejection fraction (HFNEF or
diastolic heart failure) is common, treatment outcomes on quality of life and cardiac function …

Background: Patients with heart failure and a normal left ventricular ejection fraction have
significantly reduced left ventricular long-axis function. This paper proposes an explanation …

In vivo data have been unable to provide conclusive results with regard to the relative impact
of circumferential and longitudinal shortening on stroke volume. The objective of the present …

Background—Congestive heart failure in the setting of a preserved left ventricular (LV)
ejection fraction is increasing in prevalence among the senior population. The underlying …

Pathophysiology of heart failure has been considered to be a damaged state of systolic
function of the heart followed by a state of low cardiac output that is, systolic heart failure …
