A routine of light or moderate alcohol consumption (≤1 drink/day for women and 1 to 2 drinks/day for men) were associated with a lower risk for all-cause mortality, coronary artery disease (CAD), type 2 diabetes mellitus (T2D), heart failure (HF), and stroke. Conversely, heavy drinking, (>4 drinks/day) is associated with an increased risk for death and cardiovascular (CV) disease (CVD). Excessive alcohol intake trails behind only smoking and obesity among the 3 leading causes of premature deaths in the United States (US)...

The aim was to explore the effects of non-polar and polar protic solvents composed of dichloromethane (DCM) and ethanol (EtOH) on the properties of felodipine (FLDP) and Soluplus in solutions, casting films and spray dried drug-rich or polymer-rich solid dispersions (SDs). Measurement of intrinsic viscosity and solubility indicated that FLDP and Soluplus were miscible. EtOH-DCM ranging from 20:80 to 50:50 induced the strongest molecular interactions for FLDP-Soluplus-solvents systems. Accordingly, the casting films and spray dried powders of FLDP and Soluplus were prepared using pure EtOH or DCM and their mixtures as solvents...

Ghrelin and its receptor, the growth hormone secretagogue receptor 1a (GHSR1a), are present in cardiac tissue. Activation of GHSR1a by ghrelin promotes cardiomyocyte contractility and survival, and changes in myocardial GHSR1a and circulating ghrelin track with end-stage heart failure, leading to the hypothesis that GHSR1a is a biomarker for heart failure. We hypothesized that GHSR1a could also be a biomarker for diabetic cardiomyopathy (DCM). We used two models of streptozotocin (STZ)-induced DCM: group 1, adult mice treated with 35 mg/kg STZ for 3 days; and group 2, neonatal mice treated with 70 mg/kg STZ at days 2 and 5 after birth...

Type 2 diabetes is the most prominent of all diabetes types, contributing to global morbidity and mortality. Availability and cost of treatment with little or no side effect especially in developing countries, remains a huge burden. This has led to the search of affordable alternative therapies especially from medicinal plants. In this study, the antidiabetic effect of the methanolic extract, dichloromethane (DCM), butanol (BuOH) and aqueous fractions of Clerodendrum volubile leaves were investigated in type 2 diabetic rats for their effect on glucose homeostasis, serum insulin level and hepatic biomarkers, lipid profile, pancreatic redox balance and Ca 2+ levels, and β-cell distribution and function...

Dilated cardiomyopathy (DCM) is a common primary myocardial disease leading to congestive heart failure, arrhythmia and sudden cardiac death. Increasing studies demonstrate substantial genetic determinants for DCM. Nevertheless, DCM is of substantial genetic heterogeneity, and the genetic basis for DCM in most patients remains unclear. The present study was sought to investigate the association of a genetic variant in the ZBTB17 gene with DCM. A cohort of 158 unrelated patients with idiopathic DCM and a total of 230 unrelated, ethnically matched healthy individuals used as controls were recruited...

Our previous studies showed that both exogenous and endogenous FGF21 inhibited cardiac apoptosis at the early stage of type 1 diabetes. Whether FGF21 induces preventive effect on type 2 diabetes-induced cardiomyopathy was investigated in the present study. High-fat-diet/streptozotocin-induced type 2 diabetes was established in both wild-type (WT) and FGF21-knockout (FGF21-KO) mice followed by treating with FGF21 for 4 months. Diabetic cardiomyopathy (DCM) was diagnosed by significant cardiac dysfunction, remodeling, and cardiac lipid accumulation associated with increased apoptosis, inflammation, and oxidative stress, which was aggravated in FGF21-KO mice...

BACKGROUND: Mutations of α-actin gene (ACTC1) have been phenotypically related to various cardiac anomalies, including hypertrophic cardiomyopathy and dilated cardiomyopathy and left ventricular (LV) myocardial noncompaction. A novel ACTC mutation is reported as cosegregating for familial hypertrophic cardiomyopathy and LV myocardial noncompaction with transmural crypts. METHODS AND RESULTS: In an Italian family of 7 subjects, 4 aged 10 (II-1), 14 (II-2), 43 (I-4) and 46 years (I-5), presenting abnormal ECG changes, dyspnea and palpitation (II-2, I-4, and I-5), and recurrent cerebral ischemic attack (I-5), underwent 2-dimensional echo, cardiac magnetic resonance, Holter monitoring, and next-generation sequencing gene analysis...

Background: Chronic heart failure (CHF) is life-threatening without timely or effective intervention. In this study, we investigated the association between QT dispersion corrected for heart rate (cQTd) and heart function in patients with CHF. Methods: From January 2013 to December 2015, we continuously enrolled 240 patients categorized as New York Heart Association functional class (NYHA) III-IV with a left ventricular ejection fraction (LVEF) < 40%. Based on the etiology, the patients were divided into a dilated cardiomyopathy (DCM) group ( n = 120) and an ischemic cardiomyopathy (ICM) group ( n = 120)...

Heart disease is a major health threat for Duchenne/Becker muscular dystrophy patients and carriers. Expression of a 6 to 8-kb mini-dystrophin gene in the heart holds promise to dramatically change the disease course. However the mini-dystrophin gene cannot be easily studied with adeno-associated virus (AAV) gene delivery because the size of the minigene exceeds AAV packaging capacity. We previously studied cardiac protection of the ∆H2-R19 minigene using the cardiac specific transgenic approach. Although this minigene fully normalized skeletal muscle force, it only partially corrected ECG and heart hemodynamics in dystrophin-null mdx mice that had moderate cardiomyopathy...

The definition and classification of cardiomyopathy have evolved considerably in recent years. Cardiomyopathy can be separated into primary (genetic, mixed, or acquired) and secondary categories, which result in varied phenotypes including dilated, hypertrophic, and restrictive patterns. Hypertrophic cardiomyopathy is the most common primary cardiomyopathy and can cause exertional dyspnea, presyncope, atypical chest pain, heart failure, and sudden cardiac death. Dilated cardiomyopathy can be genetic or acquired and typically presents with classic symptoms of heart failure with reduced ejection fraction...

BACKGROUND: Genetic causes of dilated cardiomyopathy (DCM) are incompletely understood. LRRC10 (leucine-rich repeat-containing 10) is a cardiac-specific protein of unknown function. Heterozygous mutations in LRRC10 have been suggested to cause DCM, and deletion of Lrrc10 in mice results in DCM. METHODS AND RESULTS: Whole-exome sequencing was carried out on a patient who presented at 6 weeks of age with DCM and her unaffected parents, filtering for rare, deleterious, recessive, and de novo variants...

Purpose: Ischemic cardiomyopathy (ICM) and non-ICM (NICM) causes of dilated cardiomyopathy with similar clinical presentation have different management and prognosis. This study employed myocardial perfusion imaging (MPI) to differentiate between the two using quantitative parameters in Indian population. Methods and Materials: Fifty patients prospectively underwent MPI and 18F-fluorodeoxyglucose metabolism studies. P values (0.05 as significant) were calculated for the left ventricular ejection fraction (EF), end diastolic volume (EDV) at rest and stress, end systolic volume (ESV) at rest and stress, summed rest score (SRS), summed difference score (SDS), and eccentricity...

OBJECTIVES: This study aimed to examine the role of nutrition in pediatric dilated cardiomyopathy (DCM). BACKGROUND: In adults with DCM, malnutrition is associated with mortality, whereas obesity is associated with survival. METHODS: The National Heart, Lung, and Blood Institute-funded Pediatric Cardiomyopathy Registry was used to identify patients with DCM and categorized by anthropometric measurements: malnourished (MN) (body mass index [BMI] <5% for ≥2 years or weight-for-length <5% for <2 years), obesity (BMI >95% for age ≥2 years or weight-for-length >95% for <2 years), or normal bodyweight (NB)...

Chronic excessive drinking leads to myocardial contractile dysfunction and dilated cardiomyopathy, where ethanol toxicity plays an essential role. Cytochrome P450 (CYP) epoxygenases metabolize arachidonic acids to form epoxyeicosatrienoic acids (EETs), which exert beneficial roles in the cardiovascular system, but their role in alcoholic cardiomyopathy is elusive. This study was designed to evaluate the effects and mechanisms of CYP2J2 gene delivery on ethanol-induced myocardial dysfunction with focus on autophagy and apoptosis...
