OBJECTIVES: This study sought to identify whether impaired global longitudinal strain (GLS), diastolic dysfunction (DD), or left atrial enlargement (LAE) should be added to stage B heart failure (SBHF) criteria in asymptomatic patients with type 2 diabetes mellitus. BACKGROUND: SBHF is a precursor to clinical heart failure (HF), and its recognition justifies initiation of cardioprotective therapy. However, original definitions of SBHF were based on LV hypertrophy and impaired ejection fraction...

BACKGROUND: Oxidative stress has been linked to heart failure (HF) in humans. Antioxidant-based treatments are often ineffective. Therefore, we hypothesize that some of the HF patients might have a reductive stress (RS) condition. Investigating RS-related mechanisms will aid in personalized optimization of redox homeostasis for better outcomes among HF patients. METHODS: Blood samples were collected from HF patients (n = 54) and healthy controls (n = 42) and serum was immediately preserved in - 80 °C for redox analysis...

Diabetic cardiomyopathy refers to a unique set of heart-specific pathological variables induced by hyperglycemia and insulin resistance. Given that cardiovascular disease (CVD) is the leading cause of death in the world, and type 2 diabetes incidence continues to rise, understanding the complex interplay between these two morbidities and developing novel therapeutic strategies is vital. Two hallmark characteristics specific to diabetic cardiomyopathy are diastolic dysfunction and cardiac structural mal-adaptations, arising from cardiac cellular responses to the complex toxicity induced by hyperglycemia with or without hyperinsulinemia...

BACKGROUND: Major classes of medical therapy for heart failure with reduced ejection fraction (HFrEF) induce reverse remodeling. The revere remodeling response to sacubitril/valsartan remains unstudied. METHODS: We performed a single-center, prospective assessor-blinded study to determine the reverse remodeling response of sacubitril/valsartan-therapy in HFrEF-patients with a class I-indication (New York heart Association [NYHA]-class II-IV, Left ventricular ejection fraction [LVEF]<35%, optimal dose with Renin-Angiotensin-System-Blocker [RAS-blocker])...

OBJECTIVES: Prolonged activation of the β-1 adrenergic receptor (ADRB1) is associated with receptor desensitization. This process has been suggested to have important pathophysiological and clinical implications in conditions such as congestive heart failure. The contribution of genetic factors to this process is a patient of ongoing research. We have previously shown that the ADRB1 389 polymorphism affects the response to incremental dose infusion of the ADRB agonist dobutamine. The aim of the current study was to determine whether the ADRB1 389 polymorphism affects the hemodynamic response to constant dose infusion of dobutamine in healthy patients...

Cardiac involvement in muscular dystrophy (MD) is known to cause heart failure (HF). However, little is known about the differences in electrocardiographic and echocardiographic findings between MD patients with and without the experience of hospitalization for HF. We retrospectively identified 95 MD patients (mean age at diagnosis of MD 41.1 ± 18.7 years; males 64.2%), including nine (9.4%) patients who were hospitalized for HF (the HF group) and 86 (90.6%) patients who were not (the non-HF group) during the follow-up period (16...

The prognosis of patients with HFrEF remains poor despite the use of current medical and device therapies. Preclinical studies of HFrEF using IC delivery of RT-100, a replication deficient, E1/E3-deleted human adenovirus 5 encoding human AC6 was associated with favorable effects on LV function and remodeling. A recent multicenter, double-blind, placebo-controlled, phase 2 study demonstrated the safety of IC delivery of RT-100 in HFrEF patients and potential efficacy at the higher doses. This phase 2 dose finding study, which included doses not expected to be effective, identified a potential reduction in congestive heart failure admissions in the AC6-treated group one year after randomization...

OBJECTIVE: Acute heart failure (AHF) is one of the most commonly seen clinical cases, with a high rate of re-hospitalization and mortality. AHF can be divided into two categories based on the systolic function of the left ventricle, which are heart failure with reduced ejection fraction (HFREF) and heart failure with preserved ejection fraction (HFPEF). Pathogenesis and treatment of the two are quite different. In this article we attempted to explore the value of combined use of clinical and laboratory indicators in the differential diagnosis of AHFREF and AHFPEF...

Heat shock protein 20 (Hsp20) has been shown to be a critical regulator of cardiomyocyte survival upon cardiac stress. In this study, we investigated the functional significance of a novel human Hsp20 mutation (S10F) in peripartum cardiomyopathy. Previous findings showed that cardiac-specific overexpression of this mutant were associated with reduced autophagy, left ventricular dysfunction and early death in male mice. However, this study indicates that females have normal function with no alterations in autophagy but died within a week after 1-4 pregnancies...

<u>Rationale:</u> Increased titin-dependent cardiomyocyte tension is a hallmark of heart failure with preserved ejection fraction (HFpEF) associated with type-2 diabetes mellitus (T2DM). However, the insulin-related signaling pathways that modify titin-based cardiomyocyte tension, thereby contributing to modulation of diastolic function, are largely unknown. <u>Objective:</u> We aimed to determine how impaired insulin signaling affects titin expression and phosphorylation and thus increases passive cardiomyocyte tension, and whether metformin or neuregulin-1 can correct disturbed titin modifications and increased titin-based stiffness...

Background: Recent clinical studies have shown that skin autofluorescence (AF) levels are significantly associated with diabetic complications. In contrast, data regarding the relationships between skin AF and chronic heart failure (CHF) are limited. The aim of this study was to clarify the clinical significance of skin AF in patients with type 2 diabetes mellitus (DM) with CHF. Methods: This cross-sectional study enrolled 257 outpatients with type 2 DM with CHF who were treated medically (96 men and 161 women; mean age, 79 ± 7 years)...

BACKGROUND: Echocardiographic assessment of systolic and diastolic function during atrial fibrillation (AF) is challenging. This study evaluates the prognostic value of strain in patients with AF and suggests a novel approach on how to take into account the varying heart cycle lengths in AF. METHODS: Echocardiograms from 204 patients with AF during examination were analyzed offline. Patients with known heart failure (HF) were excluded. Peak global longitudinal strain (GLS) was averaged from 18 myocardial segments...

Ventricular restraint therapy is a non-transplant surgical option for the management of advanced heart failure (HF). To augment the therapeutic applications, it is hypothesized that ASD shows remarkable capabilities not only in delivering stem cells but also in dilated ventricles. Male SD rats were divided into four groups (n = 6): normal, HF, HF + ASD, and HF + ASD-BMSCs respectively. HF was developed by left anterior descending (LAD) coronary artery ligation in all groups except normal group. Post-infarcted electrocardiography (ECG) and brain natriuretic peptide (BNP) showed abnormal heart function in all model groups and HF + ASD-BMSCs group showed significant improvement as compared to other HF, HF + ASD groups on day 30...

BACKGROUND: Diabetes mellitus and pre-diabetes mellitus are associated with lower body mass indices and increased risk of cardiovascular events (including heart failure) at lower glucose thresholds in Chinese compared with Western cohorts. However, the extent of cardiac remodeling and regulation on cardiac mechanics in lean and nonlean dysglycemic Chinese adults is understudied. METHODS AND RESULTS: We studied 3950 asymptomatic Chinese (aged 49.7±10.7 years; 65% male; body mass index: 24...

Cancer therapies have resulted in increased survivorship in oncological patients. However, the benefits have been marred by the development of premature cardiovascular disease. The current definition outlines measurement of ejection fraction as a mean to diagnose cancer therapeutic-related cardiac dysfunction (CTRCD); however, up to 58% of the patients do not regain their cardiac function after the CTRCD diagnosis, despite therapeutic interventions. Therefore, there has been a growing interest in the markers for early myocardial changes (ie, changes with normal left ventricular ejection fraction [LVEF]) that may predict the development of subsequent left ventricular ejection fraction reduction or progression to heart failure...

BACKGROUND: The leg-positive pressure maneuver can safely and noninvasively apply preload stress without increase in total body fluid volume. The purpose of this study was to determine whether preload stress could be useful for risk stratification of patients with heart failure with reduced ejection fraction. METHODS AND RESULTS: For this study, 120 consecutive patients with heart failure with reduced ejection fraction were prospectively recruited. The stroke work index was estimated as product of stroke volume index and mean blood pressure, and the E/e' ratio was calculated to estimate ventricular filling pressure...
