Left Ventricular Ejection Fraction (EF) of 55% as Cutoff for Late Transition From Heart Failure (HF) With Preserved EF to HF With Mildly Reduced EF.

BACKGROUND Heart failure (HF) with preserved (HFpEF) left ventricular ejection fraction (LVEF) is a syndrome with complex pathophysiology. Little is known about changes in LVEF that occur over time in HFpEF patients. A fundamental clinical question about HFpEF is whether HFpEF is an early manifestation of HF with reduced LVEF (HFrEF). If so, which patients with HFpEF are likely to show a declin...

Heart failure with preserved EF: a bird eye view.

The concept of ''diastolic'' heart failure grew out of the observation that many patients who have the symptoms and signs of heart failure had an apparently normal left ventricular (LV) ejection fraction. Thus it was assumed that since systolic function was ''pre- served'' the problem must lie in diastole, although it is not clear by whom or when this assumption was made. Nevertheless, many gui...

renin-angiotensin system antagonists might reduce mortality in heart failure with preserved ejection fraction For heart failure with preserved ejection fraction (HF-

For heart failure with preserved ejection fraction (HFPEF), there is yetno evidence available of therapies reducing mortality. Three randomized clinical trials (RCTs), CHARM preserved, PEP-CHF and I-Preserve, investigated the role of renin-angiotensin system antagonists (RASA) -angiotensin II receptor blockers (ACEIs) and angiotensin II receptor blockers (ARBs) in this settingand failed to show...

Calculation of the Ejection Fraction (EF) from MR Cardio-Images

This paper outlines an algorithm to segment images on the short-axis view of the heart, obtained from multislice and multi-phase MR (Magnetic Resonance). Using the data from the segmentation of the slices, the ejection fraction of the heart is calculated for the given sequence. Segmentation is achieved by first filtering the images using Adaptive Smoothing, which smoothes the image without shif...

Secondary Mitral Regurgitation in Heart Failure with Reduced or Preserved Left Ventricular Ejection Fraction

Secondary mitral regurgitation (MR) has been extensively studied in heart failure due to reduced ejection fraction. In contrast, the occurrence and the pathogenesis of secondary MR are much less known in heart failure with preserved ejection fraction (HFpEF). The present review aimed at describing this common but ignored feature of HFpEF. Copyright © 2013 S. Karger AG, Basel As in patients with...
