BACKGROUND: Hyponatremia is a well-known risk factor for worse outcomes in heart failure (HF) patients. The impact of hyponatremia according to the ejection fraction (EF) is unclear. We evaluated the prognostic value of hyponatremia according to HF type. METHODS AND RESULTS: The Korea Acute Heart Failure (KorAHF) registry consecutively enrolled 5625 patients. Hyponatremia was defined as serum sodium level<135mmol/L at hospital admission. HF with preserved and reduced ejection fraction were defined as an LVEF ≥50% and LVEF ≤40%, respectively...

Heart failure, with reduced ejection fraction (HFrEF) or preserved ejection fraction (HFpEF), is associated with high morbidity and mortality. Although many established pharmacological interventions exist for those patients with HFrEF, hospitalization and death rates remain high, and in those with HFpEF (over half of all heart failure patients), there are no effective therapies. Recently, the role of impaired cardiac energetic status in heart failure has gained increasing recognition with the identification of reduced metabolic capacity for carbohydrates and fatty acids, impaired function of the electron transport chain, reduced capacity to transfer ATP to the cytosol, and inefficient utilization of the energy produced...

Heart failure with preserved ejection fraction (HFpEF) is a serious clinical disease. The pathophysiology of HFpEF is complex, and specific diagnostic criteria have evolved over time. Limited data are available on the quantification of diastolic function using two-dimensional real-time echocardiography, and a simple parameter has not yet been established. The aim of this work is to evaluate new echocardiographic parameters-the diastolic wall strain of the posterior wall (DWS PW) and the vortex formation time (VFT)...

Intraventricular pressure differences (IVPDs) govern left ventricular (LV) efficient filling and are a significant determinant of LV diastolic function. Our primary aim is to assess the performance of available methods (color M-mode (CMM) and 1D/2D MRI-based methods) to determine IVPDs from intracardiac flow measurements. Performance of three methods to calculate IVPDs was first investigated via an LV computational fluid dynamics (CFD) model. CFD velocity data were derived along a modifiable scan line, mimicking ultrasound/MRI acquisition of 1D (IVPDCMM/IVPD1D MRI) and 2D (IVPD2D MRI) velocity-based IVPD information...

The relation between uric acid (UA) and heart failure has been described; however, there is little detail concerning acute heart failure (AHF) in patients with reduced versus preserved ejection fraction heart failure (HFrEF, HFpEF). We studied 324 consecutive AHF patients screened from interventional Diur-HF Trial (NCT01441245) from January 2011 to February 2016, and divided into HFrEF (EF <50%) and HFpEF (EF ≥50%). We defined hyperuricemia as serum UA ≥7.0 mg/dL in men and ≥6 mg/dL in women. Patients were followed up for 6 months after discharge...

PURPOSE OF REVIEW: The use of biomarkers in heart failure (HF) is a rapidly changing field. The purpose of this review is to assess the current evidence of the use of biomarkers for risk stratification in patients with HF with preserved ejection fraction (HFpEF). RECENT FINDINGS: Despite differences in pathophysiology between HF with reduced ejection fraction and HFpEF, traditional HF biomarkers such as brain natriuretic peptide and troponin retain prognostic value in most HFpEF-specific populations...

Obesity is defined as an excess body fat that impairs health and is associated with increased risk of heart failure (HF), particularly HF with preserved ejection fraction (HFpEF), evolving into a 'HFpEF obesity phenotype'. The interplay between obesity and cardiorespiratory fitness, primary clinical parameters in HF, requires further exploration. The contribution of body composition compartments in the development and progress of HF has been the object of numerous studies. Here we focus on how fat mass and lean tissues affect cardiorespiratory fitness, with emphasis on their effects on peak oxygen consumption...

Ischemic Heart Disease, in the absence of obstructive coronary artery disease, is prevalent in women, and constitutes a major risk factor for developing major adverse cardiovascular events, including myocardial infarction, stroke, and heart failure. For decades, diagnosis was considered benign and often minimized; however, it is now known that this etiology caries much risk and is a significant burden to the health care system. This review summarizes the current state-of-knowledge on non-obstructive ischemic heart disease (NOIHD), the association between NOIHD and left ventricular diastolic dysfunction, potential links between NOIHD and the development of heart failure with preserved ejection fraction (HFpEF), and therapeutic options and knowledge gaps for patients living with NOIHD...

AIMS: High-intensity interval training (HIIT) improves peak oxygen uptake and left ventricular diastology in patients with heart failure with preserved ejection fraction (HFpEF). However, its effects on myocardial strain in HFpEF remain unknown. We explored the effects of HIIT and moderate-intensity aerobic continuous training (MI-ACT) on left and right ventricular strain parameters in patients with HFpEF. Furthermore, we explored their relationship with peak oxygen uptake (VO2peak )...

AIMS: The failing heart is accompanied by disturbed energy metabolism with mitochondrial dysfunction. Carnitine transports fatty acids into mitochondria for β-oxidation. Decreased myocardial carnitine levels accompanied by increased plasma carnitine levels in heart failure (HF) have been reported. The plasma acylcarnitine to free carnitine ratio (AC/FC) is recognized as a marker of carnitine deficiency. We aimed to investigate the impact of the AC/FC on HF prognosis, taking into consideration differences between HF patients with preserved ejection fraction (HFpEF) and those with reduced ejection fraction (HFrEF)...

AIMS: Heart failure with preserved ejection fraction (HFpEF) accounts for 30-50% of patients with heart failure (HF). A major obstacle in HF management is the difficulty in differentiating between HFpEF and heart failure with reduced ejection fraction (HFrEF) using conventional clinical and laboratory investigations. The aim of this study is to develop robust transcriptomic and proteomic biomarker signatures that can differentiate HFpEF from HFrEF. METHODS AND RESULTS: A total of 210 HF patients were recruited in participating institutions from the Alberta HEART study...

Heart failure with preserved ejection fraction (HFpEF) is a major unmet medical need that is characterized by the presence of multiple cardiovascular and non-cardiovascular comorbidities. Foremost among these comorbidities are obesity and diabetes, which are not only risk factors for the development of HFpEF, but worsen symptoms and outcome. Coronary microvascular inflammation with endothelial dysfunction is a common denominator among HFpEF, obesity, and diabetes that likely explains at least in part the etiology of HFpEF and its synergistic relationship with obesity and diabetes...

BACKGROUND: Left ventricular ejection fraction (LVEF) is the most widely used parameter to evaluate the cardiac function in patients with heart failure (HF). However, the association between LVEF and contrast-induced nephropathy (CIN) is still controversial. Therefore, the aim of this study is to evaluate the association of LVEF with CIN and long-term mortality following coronary angiography (CAG) or intervention in patients with HF. METHODS: We analyzed 1,647 patients with HF (New York Heart Association [NYHA] or Killip class >1) undergoing CAG or intervention, including 207 (12...
