Heart failure (HF) is a complex syndrome representing the clinical endpoint of many cardiovascular diseases of different etiology. Given its prevalence, incidence and social impact, a better understanding of HF pathophysiology is paramount to implement more effective anti-HF therapies. Based on left ventricle (LV) performance, HF is currently classified as follows: (1) with reduced ejection fraction (HFrEF); (2) with mid-range EF (HFmrEF); and (3) with preserved EF (HFpEF). A central tenet of HFrEF pathophysiology is adrenergic hyperactivity, featuring increased sympathetic nerve discharge and a progressive loss of rhythmical sympathetic oscillations...

Heart failure (HF) with preserved ejection fraction (EF) (HFpEF) accounts for approximately 50% of HF cases and its prevalence relative to HF with reduced EF is rising. Hypertension (HT) is the most common co-morbidity in HFpEF patients and it is implicated in both the pathogenesis and the prognosis of the disease. Therefore, HT is a modifiable risk factor of high yield in HFpEF. We reviewed the literature for epidemiologic data supporting the co-aggregation of the two entities as well as patho-physiologic mechanisms linking HT to HFpEF...

Heart failure with preserved ejection fraction (HFpEF) has similar prevalence and prognosis as HF with reduced EF, but there is no approved treatment for HFpEF. HFpEF is common in postmenopausal women, which suggests that the absence of estrogen (E2) plays a role in its pathophysiology. With the country's growing elderly population, the prevalence of HFpEF is rapidly increasing. This has triggered a renewed urgency in finding novel approaches to preventing and slowing the progression of HFpEF. In this review, we address the role of E2 in left ventricular diastolic function and how it impacts women with HFpEF as well as animal models...

OBJECTIVES: This study sought to investigate how right ventricular (RV) contractile function and its coupling with pulmonary circulation (PC) stratify clinical phenotypes and outcome in heart failure preserved ejection fraction (HFpEF) patients. BACKGROUND: Pulmonary hypertension and RV dysfunction are key hemodynamic abnormalities in HFpEF. METHODS: Three hundred eighty seven HFpEF patients (mean age 64 ± 12 years, 59% females, left ventricular ejection fraction 59 ± 7%) underwent RV and pulmonary hemodynamic evaluation by echocardiography (entire population) and right heart catheterization (219 patients)...

BACKGROUND: Patients with atrial fibrillation (AF) have an increased risk of diastolic dysfunction and heart failure. The purpose of this study was to identify independent predictors of early (i.e., only exercise-induced) heart failure with preserved ejection fraction (HFpEF) and to describe the prevalence of early HFpEF among the patients with paroxysmal AF. METHODS AND RESULTS: One hundred patients with paroxysmal AF and preserved left ventricular ejection fraction (LVEF) underwent catheterization with left atrial pressure (LAP) measurements at rest and at the peak of arm exercise (LAP-exe)...

Despite the high prevalence of the patients with heart failure with preserved ejection fraction (HFpEF), our knowledge about this entity, from diagnostic tools to therapeutic approach, is still not well established. The evaluation of patients with HFpEF is mainly based on echocardiography, as the most widely accepted tool in cardiac imaging. Identification of left ventricular (LV) diastolic dysfunction has long been considered as the only responsible for HFpEF, and its evaluation is still "sine qua non" of HFpEF diagnostics...

Aim: To address the mechanisms responsible for the increase in LV filling pressures induced by acute hypertension transients in patients with heart failure with preserved ejection fraction (HFpEF). Methods and results: Multiple-beat pressure-volume loops were recorded during inferior vena cava occlusion in 39 HFpEF patients and 20 controls during handgrip and atrial pacing. We measured the contribution of relaxation, elastic recoil, and stiffness to instantaneous diastolic pressure using a novel processing method...

The aim of personalized medicine is to offer a tailored approach to each patient in order to provide the most effective therapy, while reducing risks and side effects. The use of mineralocorticoid receptor antagonists (MRAs) has demonstrated major benefits in heart failure with reduced ejection fraction (HFrEF), results with challenging inconsistencies in heart failure with preserved ejection fraction (HFpEF), and 'neutral' preliminary results in acute heart failure. Data derived from landmark trials are generally applied in a 'one size fits all' manner and the development and implementation of more personalized MRA management would offer the potential to improve outcomes and reduce side effects...

Multiple phase III trials over the last few decades have failed to demonstrate a clear benefit of various pharmacologic interventions in heart failure with a preserved left ventricular (LV) ejection fraction (HFpEF). Therefore, a better understanding of its pathophysiology is important. An accompanying review describes key technical and physiologic aspects regarding the deep phenotyping of arterial hemodynamics in HFpEF. This review deals with the potential of this approach to enhance our clinical, translational, and therapeutic approach to HFpEF...

INTRODUCTION: According to 2015 ESC/ERS guidelines for the diagnosis and treatment of pulmonary hypertension(PH), no specific drug is currently indicated for PH related to left heart disease( PH-LDH), i.e., the one secondary to left chronic heart failure (CHF), which coincides with the group 2 of the PH classification endorsed by the above-mentioned guidelines. In fact, adoption of therapies that specifically apply for so-called pulmonary arterial hypertension (group 1 of the PH classification) has been regarded as substantially contraindicated in patients with PH- LHD, according to current ESC/ERS guidelines...

Atrial fibrillation (AF) is associated with an increased risk for adverse events in patients with heart failure with preserved ejection fraction (HFpEF), but it is currently unknown if gender differences in these outcomes exist. To explore this hypothesis, we examined gender differences in the associations of AF with adverse outcomes in 3,385 (mean age 69 ± 9.6 years, 49% male, 89% white) patients with HFpEF from the Treatment of Preserved Cardiac Function Heart Failure With an Aldosterone Antagonist Trial...

BACKGROUND/AIMS: Heart failure (HF) is a main cause of mortality of hemodialysis (HD) patients. While HF with reduced ejection fraction (HFrEF) is known to only affect a minority of patients, little is known about the prevalence, associations with clinical characteristics and prognosis of HF with preserved ejection fraction (HFpEF). METHODS: We included 105 maintenance HD patients from the Medical University of Vienna into this prospective single-center cohort study and determined the prevalence of HFpEF (per the 2013 criteria of the European Society of Cardiology) and HFrEF (EF <45%), using standardized post-HD transthoracic echocardiography...

Aims: Prolonged central circulation transit time (TT) has long been associated with heart failure (HF) and left ventricular (LV) dysfunction. In this study, we assessed the central circulation TT using cardiovascular magnetic resonance imaging (CMR) in patients with HF of preserved ejection fraction (HFpEF) and of reduced EF (HFrEF) and investigated its relation to haemodynamics. Methods and results: Fifty eight prospectively recruited volunteers underwent CMR. TT was taken as the time between the peaks of time-intensity curves from first pass perfusion images and normalized to cardiac cycle length intervals...

AIMS: Significant recovery of left ventricular ejection fraction (LVEF) occurs in a proportion of patients with heart failure (HF) and reduced ejection fraction (HFrEF). We analysed outcomes, including mortality [all-cause, cardiovascular (CV), HF-related, and sudden death], and HF-related hospitalizations in this HF-recovered group. The primary endpoint was a composite of CV death or HF hospitalization. METHODS AND RESULTS: LVEF was assessed at baseline and at 1 year in 1057 consecutive HF patients...

Importance: With improved survival, heart failure (HF) has become a major complication for individuals with human immunodeficiency virus (HIV) infection. It is unclear if this risk extends to different types of HF in the antiretroviral therapy (ART) era. Determining whether HIV infection is associated with HF with reduced ejection fraction (HFrEF), HF with preserved ejection fraction (HFpEF), or both is critical because HF types differ with respect to underlying mechanism, treatment, and prognosis...
