Cardiovascular complications induced by high fat are one of the most challenging health problems presently. Oxidative stress, inflammation and fibrosis are major components included in the pathology of diabetic cardiomyopathy. Nuclear factor erythroid 2-related factor 2 (Nrf2) has been reported as an essential therapeutic target in various diseases for its induction of anti-oxidant enzymes, and other protective enzymes. Additionally, a number of Nrf2 activators showed strong anti-inflammatory properties. In the study, we calculated the Nrf2-dependent anti-oxidant, anti-inflammatory and anti-fibrosis effects of chrysophanol in high fat diet-induced diabetic heart injury...

Methods: Data from 471 elderly patients (aged from 60 to 100 years old) with CAD confirmed by autopsy hospitalized in our hospital from April 1969 to October 2013 were retrospectively reviewed. Patients were divided into 2 groups: AMI group(n=128) with AMI as the primary cause of death and the rest served as control group(n=343)...

Diabetic cardiomyopathy has been systematically associated with compromised mitochondrial energetics and increased generation of reactive oxygen species (ROS) that underlie its progression to heart failure. Methylene blue is a redox-drug with reported protective effects mainly on brain mitochondria. The present study was purported to characterize the effects of acute administration of methylene blue on mitochondrial respiration, H2O2 production, and calcium sensitivity in rat heart mitochondria isolated from healthy and 2 months (streptozotocin-induced) diabetic rats...

Hyperhomocysteinemia is a risk factor for adverse cardiovascular events; however, the mechanism for development of this disease is still unknown. Toll-like receptor 4 is a molecule involved in the immune response pathway and is quickly becoming a receptor of interest in the field of hypertension. In this study, we hypothesized that ablation of TLR4 mitigates cardiac mitochondrial dysfunction in a model of hyperhomocysteinemia. Five strains of mice (C57BL/6J, CBS+/-, C3H, CBS+/-/C3H and C3H/HeOuJ) 10-12 weeks old were utilized...

Machine learning is becoming a popular and important approach in the field of medical research. In this study, we investigate the relative performance of various machine learning methods such as Decision Tree, Naïve Bayes, Logistic Regression, Logistic Model Tree and Random Forests for predicting incident diabetes using medical records of cardiorespiratory fitness. In addition, we apply different techniques to uncover potential predictors of diabetes. This FIT project study used data of 32,555 patients who are free of any known coronary artery disease or heart failure who underwent clinician-referred exercise treadmill stress testing at Henry Ford Health Systems between 1991 and 2009 and had a complete 5-year follow-up...

BACKGROUND: Number of stromal cells injected in patients with ischaemic heart disease (IHD) may be of importance for the treatment efficacy, which in turn may be influenced by various patient-related factors. In this study, we investigate whether patient-related factors influence the number of autologous stromal cells reached after in vitro culture expansion for clinical therapy. METHODS: Culture expansion data from 111 patients with IHD treated with autologous stromal cells in three clinical trials were used...

INTRODUCTION: The 2010 Affordable Care Act introduced the Hospital Readmissions Reduction Program to reduce health care utilization. Diverticular disease and its complications remain a leading cause of hospitalization among gastrointestinal disease. We sought to determine risk factors for 30-day hospital readmissions after hospitalization for diverticular bleeding. MATERIALS AND METHODS: We utilized the 2013 National Readmission Database sponsored by the Agency for Healthcare Research and Quality focusing on hospitalizations with the primary or secondary discharge diagnosis of diverticular hemorrhage or diverticulitis with hemorrhage...

: Chronic heart failure is a common clinical condition characterized by persistent excessive sympathetic nervous system activation. The derangement of the sympathetic activity has relevant implications for disease progression and patient survival. Aiming to positively impact patient outcome, autonomic nervous system modulatory therapies have been developed and tested in animal and clinical studies. As a general gross assumption, direct vagal stimulation and baroreflex activation are considered equivalent. This assumption does not take into account the fact that direct cervical vagal nerve stimulation involves activation of both afferent and efferent fibers innervating not only the heart, but the entire visceral system, leading to undesired responses to and from this compartment...

OBJECTIVES: In-hospital cardiac arrest occurs in 2.6-6% of children with cardiac disease and is associated with significant morbidity and mortality. Much remains unknown about cardiac arrest in pediatric cardiac ICUs; therefore, we aimed to describe cardiac arrest epidemiology in a contemporary multicenter cardiac ICU cohort. DESIGN: Retrospective analysis within the Pediatric Cardiac Critical Care Consortium clinical registry. SETTING: Cardiac ICUs within 23 North American hospitals...

Proteinopathies are characterized by the accumulation of misfolded proteins, which ultimately interfere with normal cell function. While neurological diseases, such as Huntington disease and Alzheimer disease, are well-characterized proteinopathies, cardiac diseases have recently been associated with alterations in proteostasis. In this issue of the JCI, Fang and colleagues demonstrate that mice with cardiac-specific deficiency of the co-chaperone protein BCL2-associated athanogene 3 (BAG3) develop dilated cardiomyopathy that is associated with a destabilization of small HSPs as the result of a disrupted interaction between BAG3 and HSP70...

Defective protein quality control (PQC) systems are implicated in multiple diseases. Molecular chaperones and co-chaperones play a central role in functioning PQC. Constant mechanical and metabolic stress in cardiomyocytes places great demand on the PQC system. Mutation and downregulation of the co-chaperone protein BCL-2-associated athanogene 3 (BAG3) are associated with cardiac myopathy and heart failure, and a BAG3 E455K mutation leads to dilated cardiomyopathy (DCM). However, the role of BAG3 in the heart and the mechanisms by which the E455K mutation leads to DCM remain obscure...

PURPOSE: The purpose of this study was to compare (i) the exercise capacity and (ii) lung function prior to and immediately post cardiopulmonary exercise tests (CPET) of children who underwent early life lung resection for Congenital Pulmonary Airway Malformations (CPAM) to healthy control children. METHOD: Eight children with CPAM (four males, age 9.6 ± 1.8 years) and eight control children without respiratory disease (three males, age 9.4 ± 1.4 years) performed a CPET on a cycle ergometer, during which maximal oxygen consumption (V̇O2max ) and heart rate were measured...

AIMS: Previous studies have examined risk factors for the development of heart failure (HF) subsequent to acute coronary syndrome (ACS). Our study seeks to clarify the clinical variables that best characterize patients who remain free from HF after coronary artery bypass grafting (CABG) surgery for ACS to determine novel biological factors favouring freedom from HF in prospective translational studies. METHODS AND RESULTS: Nova Scotia residents (1995-2012) undergoing CABG within 3 weeks of ACS were included...

OBJECTIVE: Metabolic syndrome (MetS) can lead to myocardial fibrosis, diastolic dysfunction, and eventual heart failure. This study evaluated alterations in myocardial microstructure in people with MetS by using a novel algorithm to characterize ultrasonic signal intensity variation. METHODS: Among 254 participants without existing cardiovascular disease (mean age 42 ± 11 years, 75% women), there were 162 with MetS, 47 with obesity without MetS, and 45 nonobese controls...

Epicardium-derived cells (EPDCs) contribute cardiovascular cell types during development and in adulthood respond to Thymosin β4 (Tβ4) and myocardial infarction (MI) by reactivating a fetal gene programme to promote neovascularization and cardiomyogenesis. The mechanism for epicardial gene (re-)activation remains elusive. Here we reveal that BRG1, the essential ATPase subunit of the SWI/SNF chromatin-remodelling complex, is required for expression of Wilms' tumour 1 (Wt1), fetal EPDC activation and subsequent differentiation into coronary smooth muscle, and restores Wt1 activity upon MI...
