Heart failure with a normal ejection fraction.
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, heart failure with preserved LV function or heart failure with a normal ejection fraction (HFNEF). As recent studies have shown that systolic function is not entirely normal in these patients, HFNEF is the preferr...
متن کاملRole of Left Ventricular Stiffness in Heart Failure With Normal Ejection Fraction
Background—Increased left ventricular stiffness is a distinct finding in patients who have heart failure with normal ejection fraction (HFNEF). To elucidate how diastolic dysfunction contributes to heart failure symptomatology during exercise, we conducted a study using an invasive pressure-volume loop approach and measured cardiac function at rest and during atrial pacing and handgrip exercise...
متن کاملMolecular determinants of heart failure with normal left ventricular ejection fraction.
In population-based studies, heart failure with normal left ventricular (LV) ejection fraction (HFNEF) is now increasingly recognized and referred to as diastolic heart failure. However, the pathogenic mechanisms underlying HFNEF are incompletely understood, mainly because of limited availability of human myocardial biopsy material. Nevertheless, recent studies have examined in vivo hemodynamic...
متن کاملNormal left ventricular ejection fraction in older persons with congestive heart failure.
STUDY OBJECTIVES To investigate in older patients with congestive heart failure (CHF) associated with prior myocardial infarction or hypertension the relationship between normal left ventricular (LV) ejection fraction and age, gender, hypertension, prior myocardial infarction, and atrial fibrillation. DESIGN A prospective study was performed in 572 older patients (age >60 years) with CHF asso...
متن کاملHeart failure with normal left ventricular ejection fraction: what is the evidence?
Heart failure with a normal ejection fraction (HFNEF) is a common clinical problem with many unsolved questions regarding pathophysiology, diagnosis, and therapy. Although the term diastolic heart failure has been abandoned, diastolic left ventricular (LV) dysfunction together with combined systolic ventricular and arterial stiffening are considered to be the main pathophysiologic mechanisms in...
