Given the emerging recognition of left atrial structure and function as an important marker of disease in heart failure with preserved ejection fraction (HF-pEF), we investigated the association between left atrial volume and function with markers of disease severity and cardiac structure in HF-pEF. We studied 100 patients enrolled in the PhosphdiesteRasE-5 Inhibition to Improve CLinical Status and EXercise Capacity in Diastolic Heart Failure (RELAX) trial who underwent cardiac magnetic resonance (CMR), cardiopulmonary exercise testing, and blood collection before randomization...

The search for a parameter representing left ventricular relaxation from non-invasive and invasive diagnostic tools has been extensive, since heart failure (HF) with preserved ejection fraction (HF-pEF) is a global health problem. We explore here the feasibility using patient-specific cardiac computer modeling to capture diastolic parameters in patients suffering from different degrees of systolic HF. Fifty eight patients with idiopathic dilated cardiomyopathy have undergone thorough clinical evaluation, including cardiac magnetic resonance imaging (MRI), heart catheterization, echocardiography, and cardiac biomarker assessment...

OBJECTIVE: The aim of this study was to determine whether patients with heart failure (HF) who recover left ventricular ejection fraction (LVEF), termed here as 'Rec-HF', have a distinct clinical profile and prognosis compared with patients with HF and reduced LVEF (HF-REF) or HF and preserved LVEF (HF-PEF). METHODS: We evaluated and classified patients from the Spanish Heart Failure Registry into three categories based on enrollment/follow-up echocardiograms: HF-PEF (LVEF ≥50%), HF-REF (LVEF persistently <50%) and Rec-HF (LVEF on enrollment <50% but normalized during follow-up)...

Compared with heart failure (HF) with reduced ejection fraction (HF-REF), the diagnosis of HF with preserved EF (HF-PEF) is more challenging. The aim of the study was to assess the prevalence of HF-PEF among patients hospitalized for HF, to evaluate the pertinence of HF-PEF diagnosis and to compare HF-PEF and HF-REF patients with respect to outcomes. The analysis included 661 Polish patients hospitalized for HF, selected from the European Society of Cardiology (ESC)-HF Long-Term Registry. Patients with an EF of ≥50% were included in the HF-PEF group and patients with an EF of <50% - in the HF-REF group...

The most common cause of pulmonary hypertension (PH) due to left heart disease (LHD) was previously rheumatic mitral valve disease. However, with the disappearance of rheumatic fever and an aging population, nonvalvular LHD is now the most common cause of group 2 PH in the developed world. In this review, we examine the challenge of investigating patients who have PH and heart failure with preserved ejection fraction (HF-pEF), where differentiating between pulmonary arterial hypertension (PAH) and PH-LHD can be difficult, and also discuss the entity of combined precapillary and postcapillary PH...

Although patients with heart failure and preserved ejection fraction (HF-PEF) represent nearly half of the population with chronic heart failure, few evidence-based medical therapies are available. The neutral overall results of the TOPCAT trial of spironolactone in HF-PEF leave clinicians who treat heart failure with an ongoing clinical dilemma. In this review, we outline an approach to the clinical management of the patient with HF-PEF synthesizing data from available clinical trials and expert consensus.

OBJECTIVE: To explore the diagnostic values of ratios of early diastolic peak transmitral velocity(E) to late velocity(A) (E/A) and E to early diastolic peak mitral annulus velocity (E/E') for heart failure patients with preserved ejection fraction (HF-PEF). METHODS: Two hundred and sixteen healthy people were divided into <50 years, 50-59 years, 60-69 years, and ≥70 years groups to clarify the impact of aging on E/A and E/E'. Two hundred and two newly diagnosed consecutive in-patients with HF-PEF and 221 age- and sex-matched non-heart-failure subjects with risk factors of HF-PEF (negative controls) were enrolled...

AIMS: Pulmonary oedema is a common and important finding in acute heart failure (AHF). We conducted a systematic review to describe the methods used to assess pulmonary oedema in recent randomized AHF trials and report its prevalence in these trials. METHODS AND RESULTS: Of 23 AHF trials published between 2002 and 2013, six were excluded because they were very small or not randomized, or missing full-length publications. Of the remaining 17 (n = 200-7141) trials, six enrolled patients with HF and reduced ejection fraction (HF-REF) and 11, patients with both HF-REF and HF with preserved ejection fraction (HF-PEF)...

Randomized controlled trials (RCTs) are essential to develop advances in heart failure (HF). The need for increasing numbers of patients (without substantial cost increase) and generalization of results led to the disappearance of international boundaries in large RCTs. The significant geographic differences in patients' characteristics, outcomes, and, most importantly, treatment effect observed in HF trials have recently been highlighted. Whether the observed regional discrepancies in HF trials are due to trial-specific issues, patient heterogeneity, structural differences in countries, or a complex interaction between factors are the questions we propose to debate in this review...

OBJECTIVES: The aim of this study was to investigate N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels and recent heart failure (HF) hospitalization as predictors of future events in heart failure - preserved ejection fraction (HF-PEF). BACKGROUND: Recently, doubt has been expressed about the value of a history of HF hospitalization as a predictor of adverse cardiovascular outcomes in patients with HF and HF-PEF. METHODS: We estimated rates and adjusted hazard ratios (HRs) for the composite endpoint of cardiovascular death or HF hospitalization, according to history of recent HF hospitalization and baseline NT-proBNP level in the I-PRESERVE (Irbesartan in Heart Failure with Preserved systolic function) trial...

Heart failure with preserved ejection fraction (HF-PEF) represents half of all heart failure. Morbi-mortality for HF-PEF is similar to that of reduced ejection fraction HF (HF-REF). Diagnosis of HF-REF is difficult because of the lack of highly specific criteria. It is based on the presence of signs and symptoms of heart failure, associated with a preserved or moderately decreased left ventricular function, the absence of left ventricular dilatation, and the presence of relevant structural disease such as left ventricular hypertrophy...
