OBJECTIVES: Readmission is a common and serious problem associated with heart failure (HF). Unfortunately, conventional risk models have limited predictive value for predicting readmission. The recipients of long-term care insurance (LTCI) are frail and have mental and physical impairments. We hypothesised that adjustment of the conventional risk score with an LTCI certificate enables a more accurate appreciation of readmission for HF. METHODS: We investigated 452 patients with HF who were followed up for 1 year to determine all-cause readmission...

RATIONALE: Nitrate-rich beetroot juice has been shown to improve exercise capacity in Heart Failure with Preserved Ejection Fraction (HFpEF), but studies using pharmacologic preparations of inorganic nitrate are lacking. OBJECTIVE: To determine: (1) the dose-response effect of potassium nitrate (KNO3) on exercise capacity; (2) the population-specific pharmacokinetic and safety profile of KNO3 in HFpEF. METHODS AND RESULTS: We randomized 12 subjects with HFpEF to oral KNO3 (n=9) or potassium chloride (KCl, n=3)...

BACKGROUND AND PURPOSE: Heart failure with preserved ejection fraction (HFpEF) is a systemic syndrome driven by co-morbidities and its pathophysiology is poorly understood. Several studies suggesting that dipeptidyl peptidase 4 (DPP4) might be involved in the pathophysiology of heart failure prompted experimental and clinical investigations of DPP4 inhibitors on cardiovascular system. The aim of our study was to determine whether DPP4 inhibitor sitagliptin (SITA) affects the progression of HFpEF independently from the effects on glycaemia...

BACKGROUND: The contribution of diabetes to the burden of heart failure (HF) remains largely undescribed. Assessing diabetes temporal trends among US patients hospitalized with HF and their relation with quality measures in real-world practice can help to define this burden. METHODS: Using data from the Get With the Guidelines-Heart Failure registry, we assessed temporal trends in diabetes prevalence among patients with HF and in subgroups with reduced ejection fraction (HFrEF; EF < 40%), borderline EF (HFbEF; 40%≤EF <50%), or preserved EF (HFpEF; EF ≥ 50%), hospitalized between 2005 and 2015...

BACKGROUND: Mineralocorticoid receptor antagonists (MRAs) have been associated with improved patient outcomes in patients with heart failure with reduced ejection fraction (HFrEF) but not preserved ejection fraction (HFpEF). We conducted a systematic review and meta-analysis of selective and nonselective MRAs in HFrEF and HFpEF. METHODS: We searched Cochrane Central Register of Controlled Trials, MEDLINE and EMBASE. We included randomized controlled trials (RCT) of MRAs in adults with HFpEF or HFrEF if they reported data on major adverse cardiac events or drug safety...

BACKGROUND: Kynurenine is a circulating metabolite from the essential amino acid tryptophan. Accelerated degradation of kynurenine in skeletal muscle has been reported to provide an anti-inflammatory effect. The aim of this study was to investigate the association between blood kynurenine and muscle mass/function in patients with heart failure (HF), in whom diseased muscle mass/function plays a pathophysiological role.Methods and Results:Plasma kynurenine was assessed in 249 patients with HF (67±11 years, 21% women) and in 45 controls from the SICA-HF study...

Systemic amyloidoses are rare and proteiform diseases, caused by extracellular accumulation of insoluble misfolded fibrillar proteins. Prognosis is dictated by cardiac involvement, which is especially frequent in light chain (AL) and in transthyretin variants (ATTR, both mutated, (ATTRm), and wild-type, (ATTRwt)). Recently, ATTRwt has emerged as a potentially relevant cause of a heart failure with preserved ejection fraction (HFpEF). Cardiac amyloidosis is an archetypal example of restrictive cardiomyopathy, with signs and symptoms of global heart failure and diastolic dysfunction...

The burden of heart failure (HF) increases worldwide with an aging population, and there is a high unmet medical need in both, heart failure with reduced ejection fraction (HFrEF) and with preserved ejection fraction (HFpEF). The nitric oxide (NO) pathway is a key regulator in the cardiovascular system and modulates vascular tone and myocardial performance. Disruption of the NO-cyclic guanosine monophosphate (cGMP) signaling axis and impaired cGMP formation by endothelial dysfunction could lead to vasotone dysregulation, vascular and ventricular stiffening, fibrosis, and hypertrophy resulting in a decline of heart as well as kidney function...

Heart failure (HF) is a rapidly growing public health problem and the leading cause of morbidity, mortality, and hospitalization in populations > 65 years. The elderly HF patients have an increased prevalence of HF with preserved ejection fraction and comorbidities, may present with atypical symptoms and signs, have a higher risk for adverse drug reactions, and worse prognosis as compared with younger patients. Moreover, there is a lack of evidence-based therapies for this population because they are underrepresented in the clinical trials...

A high resting heart rate (≥70-75 b.p.m.) is a risk factor for patients with heart failure (HF) with reduced ejection fraction (EF), probably in the sense of accelerated atherosclerosis, with an increased morbidity and mortality. Beta-blockers not only reduce heart rate but also have negative inotropic and blood pressure-lowering effects, and therefore, in many patients, they cannot be given in the recommended dose. Ivabradine specifically inhibits the pacemaker current (funny current, If) of the sinoatrial node cells, resulting in therapeutic heart rate lowering without any negative inotropic and blood pressure-lowering effect...

AIMS: Accumulation of extracellular matrix (ECM) is known to play a crucial role in the pathophysiology of heart failure (HF). However, its prognostic relevance is poorly investigated. METHODS AND RESULTS: A total of 73 HF patients who underwent LV endomyocardial biopsy were enrolled in our study. ECM area was quantified by TissueFAXS and ImageJ software. Patients were followed-up at 6-month intervals. The study endpoint was defined as hospitalization for a cardiac reason and/or cardiac death...

: Impaired diastolic filling is a main contributor to heart failure with preserved ejection fraction (HFpEF), a syndrome with increasing prevalence and no treatment. Both collagen and the giant sarcomeric protein titin determine diastolic function. Since titin's elastic properties can be adjusted physiologically, we evaluated titin-based stiffness as a therapeutic target. We adjusted RBM20-dependent cardiac isoform expression in the titin N2B knockout mouse with increased ventricular stiffness...

Combining echocardiography and cardiopulmonary stress testing allows noninvasive assessment of hemodynamics, and oxygen extraction (A-VO2 difference). We evaluated mechanisms of effort intolerance in patients with heart failure with borderline (40% to 49%) left ventricular ejection fraction (EF) (HF and Borderline Ejection fraction). We included 89 consecutive patients with HF and Borderline Ejection fraction (n = 25; 63.6 ± 14 years, 64% men), control subjects (n = 22), patients with HF with preserved EF (n = 26; EF ≥50%), and patients with HF with reduced EF (n = 16; <40%)...

BACKGROUND: Heart failure with reduced ejection fraction (HFrEF) exhibits a "reverse metabolic profile". Whether this profile exists in HF with preserved ejection fraction (HFpEF) is unknown. We tested the hypothesis that HFpEF and HFrEF are similar regarding concentrations of and prognostic impact of leptin and adiponectin. METHODS: In patients with HFpEF(n=79), HFrEF(n=84), and controls(n=71), we analyzed serum leptin and adiponectin concentrations, their correlations, and associations with outcome...

AIMS: Impaired left ventricular (LV) deformation despite preserved LV ejection fraction (LVEF) is common and predicts outcomes in heart failure with preserved LVEF. We hypothesized that impaired LV deformation at rest is a marker of impaired cardiac systolic and diastolic reserve, and aimed to determine whether resting longitudinal (LS) and circumferential strain (CS) are associated with invasively measured haemodynamic response to exercise in patients with dyspnoea and a normal LVEF...

PGC-1α, a key regulator of energy metabolism, seems to be a relevant therapeutic target to rectify the energy deficit observed in heart failure (HF). Since our previous work has shown positive effects of cobalamin (Cb) on PGC-1α cascade, we investigate the protective role of Cb in pressure overload-induced myocardial dysfunction. Mice were fed with normal diet (ND) or with Cb and folate supplemented diet (SD) 3weeks before and 4weeks after transverse aortic constriction (TAC). At the end, left ventricle hypertrophy and drop of ejection fraction were significantly lower in SD mice than in ND mice...

PURPOSE: Urapidil is putatively effective for patients with hypertension and acute heart failure, although randomized controlled trials thereon are lacking. We investigated the efficacy and safety of intravenous urapidil relative to that of nitroglycerin in older patients with hypertension and heart failure in a randomized controlled trial. MATERIALS AND METHODS: Patients (>60 y) with hypertension and heart failure were randomly assigned to receive intravenous urapidil (n=89) or nitroglycerin (n=91) for 7 days...

AIMS: We recently showed that sildenafil did not improve pulmonary pressures and exercise capacity in a cohort of patients with heart failure and preserved ejection fraction (HFpEF) and predominantly postcapillary pulmonary hypertension. Here, we present the effects of sildenafil on cardiac structure and function, cardiopulmonary exercise testing, laboratory parameters and health-related quality of life measures. METHODS AND RESULTS: Fifty-two HFpEF patients with pulmonary hypertension (mean pulmonary artery pressure >25 mmHg; pulmonary artery wedge pressure >15 mmHg) were randomized to sildenafil 60 mg three times a day or placebo and treated for 12 weeks...
