OBJECTIVES: The purpose of this study was to describe the temporal trends in prevalence of left ventricular systolic dysfunction (LVSD) in individuals without and with heart failure (HF) in the community over a 3-decade period of observation. BACKGROUND: Temporal trends in the prevalence and management of major risk factors may affect the epidemiology of HF. METHODS: We compared the frequency, correlates, and prognosis of LVSD (left ventricular ejection fraction [LVEF] <50%) among Framingham Study participants without and with clinical HF in 3 decades (1985 to 1994, 1995 to 2004, and 2005 to 2014)...

Rationale: Cortical bone stem cells (CBSCs) have been shown to reduce ventricular remodeling and improve cardiac function in a murine myocardial infarction (MI) model. These effects were superior to other stem cell types that have been used in recent early stage clinical trials. However, CBSC efficacy has not been tested in a preclinical large animal model using approaches that could be applied to patients. Objective: To determine if post-MI transendocardial injection of allogeneic CBSCs reduces pathological structural and functional remodeling and prevents the development of heart failure in a swine MI model...

Noonan Syndrome with Multiple Lentigines (NSML) is associated with congenital heart disease in form of pulmonary valve stenosis and hypertrophic cardiomyopathy (HCM). Genetically, NSML is primarily caused by mutations in the non-receptor protein tyrosine phosphatase SHP2. Importantly, certain SHP2 mutations such as Q510E can cause a particularly severe form of HCM with heart failure in infancy. Due to lack of insight into the underlying pathomechanisms, an effective custom-tailored therapy to prevent heart failure in these patients has not yet been found...

Pulmonary hypertension (PH) related to left heart disease (LHD) is the most common form of PH, accounting for more than two third of all PH cases. The hemodynamic abnormalities seen in PH-LHD are complex, and there are currently minimal evidence-based recommendations for the management of PH-LHD. While it is accepted that PH in the context of left heart disease is a marker of worse prognosis, it remains unclear whether its primary treatment is beneficial or harmful. In this article, we discuss the prevalence and significance of PH in patients with heart failure (HF) with reduced ejection fraction (HFrEF) as well as HF with preserved ejection fraction (HFpEF), and those with valvular heart disease and provide insights into the complex pathophysiology of cardiopulmonary interrelationship in individuals with PH due to left heart disease...

BACKGROUND: In human heart failure, Ser199 (equivalent to Ser200 in mouse) of cTnI (cardiac troponin I) is significantly hyperphosphorylated, and in vitro studies suggest that it enhances myofilament calcium sensitivity and alters calpain-mediated cTnI proteolysis. However, how its hyperphosphorylation affects cardiac function in vivo remains unknown. METHODS AND RESULTS: To address the question, 2 transgenic mouse models were generated: a phospho-mimetic cTnIS200D and a phospho-silenced cTnIS200A, each driven by the cardiomyocyte-specific α-myosin heavy chain promoter...

BACKGROUND: The relationship between left ventricular (LV) function and longitudinal or radial contraction has not yet been elucidated in patients with acute Kawasaki disease (KD), especially before and after intravenous immunoglobulin (IVIG) administration. METHODS: We studied 28 KD patients without coronary aneurysms (average 3.2 years). The LV end-diastolic volume (LVEDV), end-systolic volume (LVESV), stroke volume (LVSV), and ejection fraction (LVEF) were assessed using three-dimensional echocardiography before IVIG, after IVIG administration, and in the convalescent phase...

AIM: Heart failure with preserved ejection fraction (HFpEF) is associated with myocardial remodelling including severe pro-fibrotic changes contributing to an increase in left ventricular stiffness and diastolic dysfunction. Serum C-terminal propeptide of procollagen type I (PIP) strongly correlates with the turnover of extracellular cardiac matrix proteins and fibrosis. Torasemide, but not furosemide, was described to reduce collagen type I synthesis in clinically unstable patients with heart failure with reduced ejection fraction...

BACKGROUND: Cardiac troponin (cTn) has been established as an effective prognostic marker in acute heart failure (HF) with predominantly reduced ejection fraction. However, it's prognostic value in heart failure with preserved ejection fraction (HFpEF) is unclear. The aim of this study is to describe the prognostic role of troponin I in patients hospitalized for HFpEF decompensation. METHODS: We included 363 consecutive patients admitted for HFpEF decompensation that was not associated with acute coronary syndrome (ACS)...

REVIEW
Martin R Cowie, Angela M Gallagher
Most patients with heart failure (HF) have sleep-disordered breathing (SDB), with central (rather than obstructive) sleep apnea becoming the predominant form in patients with more severe disease. Cyclical apnea and hypopneas are associated with sleep disturbance, hypoxemia, hemodynamic changes, and sympathetic activation. These patients have a worse prognosis than those without SDB. Mask-based therapies of positive airway pressure targeted at SDB can improve measures of sleep quality and can partially normalize the sleep and respiratory physiology...

Heart failure is associated with mitochondrial dysfunction so that restoring or improving mitochondrial health is of therapeutic importance. Recently, reduction in NAD(+) levels and NAD(+)-mediated deacetylase activity has been recognized as negative regulators of mitochondrial function. Using a cardiac specific KLF4 deficient mouse line that is sensitive to stress, we found mitochondrial protein hyperacetylation coupled with reduced Sirt3 and NAD(+) levels in the heart before stress, suggesting that the KLF4-deficient heart is predisposed to NAD(+)-associated defects...

The need for noninvasive assessment of cardiac volumes and ejection fraction (EF) ushered in the use of cardiac imaging techniques in heart failure (HF) trials that investigated the roles of pharmacological and device-based therapies. However, in contrast to HF with reduced EF (HFrEF), modern HF pharmacotherapy has not improved outcomes in HF with preserved EF (HFpEF), largely attributed to patient heterogeneity and incomplete understanding of pathophysiological insights underlying the clinical presentations of HFpEF...

BACKGROUND: In acute decompensated heart failure patients with a preserved or reduced ejection fraction, the association of admission and discharge anemia status with outcomes remains unclear. METHODS AND RESULTS: Of the 4842 patients enrolled in the Acute Decompensated Heart Failure Syndromes (ATTEND) registry, 4433 patients (2017 with a preserved and 2416 with a reduced ejection fraction) were examined to investigate associations among the anemia status at admission and discharge (no anemia, developed anemia, resolved anemia, or persistent anemia), a preserved or reduced ejection fraction and the primary endpoint (all-cause death and readmission for heart failure)...

Surgical stress, liberation of cytokines associated with re-perfusion injury, and long standing use of immune suppressive medications in children recipients of orthotopic living related liver transplantation (OLRLT) pose cardiovascular risk. Reported cardiovascular adverse effects vary from left ventricular wall thickening, hypertrophic cardiomyopathy to resting ECG abnormalities, asymptomatic ST depression following increased heart rate and ventricular arrhythmias. Twenty-five consecutive children recipients of OLRLT were assessed by conventional 2-D, M-mode echocardiography and Doppler...

Rationale: Downregulation of connexin 43 (Cx43), the major cardiac gap junction protein, is often associated with arrhythmia, dilated cardiomyopathy (DCM) and heart failure. However, the cause of the reduced expression remains elusive. Re-induction of a nuclear RNA-binding protein CUGBP, Elav-like family member 1 (CELF1) in the adult heart has been implicated in the cardiac pathogenesis of myotonic dystrophy type 1 (DM1). However, how elevated CELF1 level leads to cardiac dysfunction, such as conduction defect, DCM and heart failure, remains unclear...

AIMS: Hospitalizations for heart failure (HF) are common and are associated with significant morbidity, mortality and cost. However, precipitating factors leading to HF hospitalization and their importance with respect to subsequent outcomes are not well understood. METHODS AND RESULTS: The symptoms and signs present at admission and investigator-identified factors thought to have contributed to the first adjudicated HF hospitalization in the Candesartan in Heart Failure: Assessment of Reduction in Mortality and Morbidity (CHARM) programme were prospectively collected and stratified by ejection fraction (EF)...
