OBJECTIVES: This study evaluated the prevalence, profile, and prognosis of severe obesity in a large contemporary acute heart failure (AHF) population. BACKGROUND: Better prognosis has been reported for obese heart failure (HF) patients than nonobese HF patients, but in other cardiovascular populations, this effect has not been demonstrated for severely obese patients. METHODS: A cohort of 795 participants with body mass index (BMI) measured at time of admission and complete follow-up were identified from enrollment in 3 contemporary AHF trials (DOSE [Diuretic Strategies Optimization Evaluation], CARRESS-HF [Cardiorenal Rescue Study in Acute Decompensated Heart Failure], and ROSE [Renal Optimization Strategies Evaluation in Acute Heart Failure])...

: 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...

PURPOSE: To investigate the cardiac safety of adjuvant Non-Pegylated Liposomal Doxorubicin (NPL-DOX) combined to Cyclophosphamide (CTX) and followed by weekly Paclitaxel, in older patients (≥65 years) with diagnosis of high risk breast cancer. The main end point of this prospective study was the detection of early episodes of symptomatic congestive heart failure (CHF). METHODS: The cardiac function was evaluated by left ventricular ejection fraction (LVEF) measurements with repeated echocardiograms, performed 2 weeks before the beginning of chemotherapy and every 6 months, until 30 months after the study entry; then yearly for at least 5 years...

BACKGROUND: N-terminal pro-brain natriuretic peptide (NT-proBNP) is seen to be mostly elevated in patients with acute heart failure (AHF). However, cases of AHF presenting with low NT-proBNP levels have been reported. In this study designed to investigate the factors associated with low NT-proBNP levels in AHF patients, we discovered that etiology and related factors have an influence on NT-proBNP levels. METHODS: In this study, 154 AHF patients met the study criteria (117 men, median age 74years; left ventricular ejection fraction [LVEF] 46±13%; New York Heart Association [NYHA] classes II-IV)...

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...

The new percutaneous Impella CP (Cardiac Power; Abiomed, Inc., Danvers, MA) was designed to provide a higher level of support than Impella 2.5 (Abiomed, Inc.). We present the first documented case of a patient that was transitioned from the Impella 2.5 to Impella CP. A 48-year-old male patient with no medical history was transferred to our institution with a one day history of worsening shortness of breath. The patient was unstable and found to have monomorphic ventricular tachycardia at 220 beats/min that was cardioverted to normal sinus rhythm...

AIMS: To evaluate whether the clinical and echocardiographic correlates and the prognostic significance of right ventricular (RV) dysfunction are different in heart failure patients with reduced (HFrEF), mid-range (HFmrEF), or preserved (HFpEF) left ventricular ejection fraction. METHODS AND RESULTS: The study included 1663 patients with heart failure caused by ischaemic or hypertensive heart disease or by idiopathic cardiomyopathy. Left ventricular ejection fraction was <40% in 1123 patients (HFrEF), 40-49% in 156 patients (HFmrEF) and ≥50% in 384 patients (HFpEF)...

The new guidelines for the diagnosis and treatment of acute and chronic heart failure (HF) were presented in May 2016 during the congress of the Heart Failure Association (HFA) of the European Society of Cardiology (ESC) in Florence. An important amendment affects the classification of HF which now differentiates between HF with preserved ejection fraction (HFpEF) and left ventricular EF (LVEF) > 50%, HF with reduced ejection fraction (HFrEF, LVEF < 40%) and the new entity HF with mid-range ejection fraction (HFmrEF, LVEF 40-49%)...

BACKGROUND: Left ventricular diastolic dysfunction (LVDD) is closely related to heart failure with preserved ejection fraction (HFpEF), while the prevalence and correlates of either LVDD or HFpEF in elderly population remain largely unknown. METHODS: The study was performed in 1274 community residents (769 women, aged ≥65years) who participated in the Shanghai Heart Health Study. Demographic, laboratory and echocardiographic data were obtained to analyze correlates of LVDD and HFpEF using univariate and multivariate Logistic analysis...

Heart failure (HF) progression has not been studied in pediatric patients as well as HF in patients with a normal ejection fraction (HFNEF). We aimed to evaluate galactin-3 in children with HFNEF and reduced ejection fraction (HFREF) and its correlation to disease severity and progression. This cross-sectional study involved 45 chronic HF patients taking G1a (23 HFNEF children) and G1b (22 HFREF children) compared to 45 age- and sex-matched controls (G2) subjected to history taking, Ross functional HF classification, conventional and tissue Doppler echocardiographic systolic and diastolic function assessment (FS%, E/A, S m, E m/A m, E/E m) and laboratory investigations [glomerular filtration rate, serum galactin-3 level (ELISA)]...

Background. Inflammation plays a crucial role in the progression of chronic heart failure (CHF). Ivabradine is known to reduce the morbidity and mortality of patients with CHF under certain conditions. Beyond the reduction of heart rate, only limited knowledge exists about potential anti-inflammatory effects of ivabradine that might contribute to its benefit in CHF. Thus, the present study aimed to investigate the effect of ivabradine on systemic inflammation. Methods. In the present study, 33 patients with CHF due to dilated, ischemic, and hypertensive cardiomyopathy were treated with ivabradine according to the guidelines of the European Society of Cardiology (ESC)...

The failing heart has an increased metabolic demand and at the same time suffers from impaired energy efficiency, which is a detrimental combination. Therefore, therapies targeting the energy-deprived failing heart and rewiring cardiac metabolism are of great potential, but are lacking in daily clinical practice. Metabolic impairment in heart failure patients has been well characterized for patients with reduced ejection fraction, and is coming of age in patients with 'preserved' ejection fraction. Targeting cardiomyocyte metabolism in heart failure could complement current heart failure treatments that do improve cardiovascular haemodynamics, but not the energetic status of the heart...

Patients with asymptomatic heart failure (HF; stage A and B) are characterized by maladaptive left ventricular (LV) remodeling. Classic 4-group classification of remodeling considers only LV mass index and relative wall thickness as variables. Complex remodeling classification (CRC) includes also LV end-diastolic volume index. Main aim was to assess the prognostic impact of CRC in stage A and B HF. A total of 1,750 asymptomatic subjects underwent echocardiographic examination as a screening evaluation in the presence of cardiovascular risk factors...

AIMS: Iron deficiency (ID) is highly prevalent in patients with heart failure (HF) worldwide regardless of haemoglobin levels. Results from therapeutic trials of intermittently dosed intravenous (i.v.) iron are promising in the ambulatory Caucasian population with HF with reduced left ventricular ejection fraction, although evidence is scarce in Asia. The Pilot Randomized Controlled Trial to Assess the Role of Intravenous Ferric Carboxymaltose in Asian Patients with Heart Failure aims to assess the effect of single-dose i...

AIMS: Data on the prognostic role of left and right bundle branch blocks (LBBB and RBBB), and nonspecific intraventricular conduction delay (IVCD; QRS ≥ 110 ms, no BBB) in acute heart failure (AHF) are controversial. Our aim was to investigate electrocardiographic predictors of long-term survival in patients with de novo AHF and acutely decompensated chronic heart failure (ADCHF). METHODS AND RESULTS: We analysed the admission electrocardiogram of 982 patients from a multicenter European cohort of AHF with 3...

BACKGROUND: Acute heart failure (AHF) is a leading cause of death in critically ill patients and is often accompanied by significant renal dysfunction. Few data exist on the predictive value of measures of renal dysfunction in large cohorts of patients hospitalized for AHF. METHODS: Six hundred and eighteen patients hospitalized for AHF (300 male, aged 73.3 ± 10.3 years, 73% New York Heart Association Class 4, mean hospital length of stay 12.9 ± 7.7 days, 97% non-ischaemic AHF) were included in a retrospective single-centre data analysis...

BACKGROUND: Insulin-like growth factor binding protein-7 (IGFBP-7) modulates the biological activities of insulin-like growth factor-1 (IGF-1). Previous studies demonstrated the prognostic value of IGFBP-7 and IGF-1 among patients with systolic heart failure (HF). This study aimed to evaluate the IGF1/IGFBP-7 axis in HF patients with preserved ejection fraction (HFpEF). METHODS: Serum IGF-1 and IGFBP-7 levels were measured in 300 eligible consecutive patients who underwent comprehensive cardiac assessment...

BACKGROUND: Junctophilin-2 (JPH2) is the primary structural protein for the coupling of transverse (T)-tubule associated cardiac L-type Ca channels and type-2 ryanodine receptors on the sarcoplasmic reticulum within junctional membrane complexes (JMCs) in cardiomyocytes. Effective signaling between these channels ensures adequate Ca-induced Ca release required for normal cardiac contractility. Disruption of JMC subcellular domains, a common feature of failing hearts, has been attributed to JPH2 downregulation...

Current Hypertension Guidelines emphasize the importance of assessing the presence of preclinical organ damage. In fact, an extensive evaluation of organ damage may increase the number of patients classified at high CV risk and therefore strongly influence the clinical management of patients. Hypertensive heart disease remains to date the form of organ damage for which there is the greatest amount of evidence of a strong independent prognostic significance. In the presence of a chronic pressure overload, a parallel addition of sarcomers takes place with an increase in myocyte width, which in turn increases left ventricular wall thickness; myocyte hypertrophy is also associated with apoptosis, collagen deposition and ventricular fibrosis with an impairment of coronary hemodynamics as well, thus profoundly influencing functional properties of the left (and right) ventricle...
