In 2012, the World Health Organization Global Status Report on noncommunicable diseases showed that 7.4 million deaths were due to ischemic heart disease. Consequently, cardiovascular disease is a significant health burden, especially when partnered with comorbidities such as obesity, metabolic syndrome, and type 2 diabetes mellitus. Of note, these diseases can all be induced or exacerbated by diet. Carbohydrates, in particular, fructose and glucose, generally form the largest part of the human diet. Accumulating evidence from animal studies suggests that if large amounts of fructose are consumed either in isolation or in combination with glucose (fructose-containing sugars), myocardial susceptibility to ischemia/reperfusion (I/R) injury increases...

BACKGROUND: Because of global aging, the prevalence of heart failure with preserved ejection fraction (HFpEF) continues to rise. Although HFpEF pathophysiology remains incompletely understood, endothelial inflammation is stated to play a central role. Cellular senescence is a process of cellular growth arrest linked with aging and inflammation. We used mice with accelerated aging to investigate the role of cellular senescence in HFpEF development. METHODS AND RESULTS: Senescence-accelerated mice (SAM, n=18) and control mice with normal senescence (n=15) were fed normal chow or a high-fat, high-salt diet (WD)...

OBJECTIVES: In established acute coronary syndrome (ACS) with major complications (i.e. heart failure), overweight/obese patients usually have a survival advantage. To what extent this is irrespective of other characteristics remains inconclusive. The role of body mass index (BMI) in ACS prognosis (fatal/recurrent non-fatal cardiac episodes) and background potential interactions were evaluated. STUDY DESIGN: In 2006-2009, 1000 consecutive patients, hospitalized at First Cardiology Clinic of Athens with a diagnosis of ACS were enrolled in the study...

BACKGROUND: Food insecurity, the uncertain ability to access adequate food, can limit adherence to dietary measures needed to prevent and manage cardiometabolic conditions. However, little is known about temporal trends in food insecurity among those with diet-sensitive cardiometabolic conditions. METHODS: We used data from the Continuous National Health and Nutrition Examination Survey (NHANES) 2005-2012, analyzed in 2015-2016, to calculate trends in age-standardized rates of food insecurity for those with and without the following diet-sensitive cardiometabolic conditions: diabetes mellitus, hypertension, coronary heart disease, congestive heart failure, and obesity...

BACKGROUND: Depression and health behavior engagement are a critical issue for recovery and secondary prevention in heart failure patients. No prior studies have examined these important clinical outcomes in young women diagnosed with Peripartum Cardiomyopathy (PPCM). We sought to characterize the prevalence of depression and health behaviors in PPCM patients and examine whether depression is associated with reduced engagement in health behaviors. METHODS: A nation-wide, cohort of 177 PPCM patients (mean age of 34...

Extracellular fluid volume overload and its inevitable consequence, hypertension, increases cardiovascular mortality in the long term by leading to left ventricular hypertrophy, heart failure, and ischemic heart disease in dialysis patients. Unlike antihypertensive medications, a strict volume control strategy provides optimal blood pressure control without need for antihypertensive drugs. However, utilization of this strategy has remained limited because of several factors, including the absence of a gold standard method to assess volume status, difficulties in reducing extracellular fluid volume, and safety concerns associated with reduction of extracellular volume...

We have previously reported that epoxyeicosatrienoic acid (EET) has multiple beneficial effects on vascular function, in addition to its anti-apoptotic action, it increases insulin sensitivity and inhibits inflammation. To uncover the signaling mechanisms by which EET reduces cardiomyopathy, we hypothesized that EET infusion might ameliorate obesity-induced cardiomyopathy by improving HO-1, Wnt1, thermogenic gene levels and mitochondrial integrity in cardiac tissues and improved pericardial fat phenotype. EET reduced levels of fasting blood glucose, and pro-inflammatory adipokines including NOV signaling while increasing echocardiographic fractional shortening and O2 consumption...

BACKGROUND: The kidney is always subjected to high metabolic demand. The aim of this study was to characterize metabolic profiles of a rat model of chronic kidney disease (CKD) with cardiorenal syndrome (CRS) induced by prolonged hypertension. METHODS: We used inbred male Dahl salt-sensitive (DS) rats fed an 8% NaCl diet from six weeks of age (high-salt; HS group) or a 0.3% NaCl diet as controls (low-salt; LS group). We analyzed function, pathology, metabolome, and the gene expression related to energy metabolism of the kidney...

Cardiovascular diseases are the main cause of mortality and morbidity in the world. Hypertension, ischemia/reperfusion, diabetes and anti-cancer drugs contribute to heart failure through oxidative and nitrosative stresses which cause cardiomyocytes nuclear and mitochondrial DNA damage, denaturation of intracellular proteins, lipid peroxidation and inflammation. Oxidative or nitrosative stress-mediated injury lead to cardiomyocytes apoptosis or necrosis. The reactive oxygen (ROS) and nitrogen species (RNS) concentration is dependent on their production and on the expression and activity of anti-oxidant enzymes...

Type 2- diabetes mellitus (T2DM) represents a major risk factor for cardiovascular complications and mortality. Strict glucose control in the early course of the disease prevents cardiovascular complications only in the long run. Non-medical therapies (diet, exercise, body weight reduction) bear little evidence for positive cardiovascular effects.Bariatric surgery is not number one choice in therapy of T2DM. Metformin seems to provide positive cardiovascular effects. Insulin seems to be cardiovascular neutral, as well as the DPP4-inhibitors Saxagliptin, Sitagliptin and Alogliptin...

DNA methylation is a major epigenetic mechanism to regulate gene expression. Epigenetic regulation, including DNA methylation, histone modifications and RNA interference, results in heritable changes in gene expression independent of alterations in DNA sequence. Epigenetic regulation often occurs in response to aging and environment stimuli, including exposures and diet. Studies have shown that DNA methylation is critical in the pathogenesis of fibrosis involving multiple organs sytems, contributing to significant morbidity and mortality...

Diabetic cardiomyopathy (DCM), a metabolic disorder, is one of the leading causes of mortality around the world and its pathogenesis involves cardiac inflammation and altered metabolic profile. Altered fatty acid metabolism during DCM can cause macrophage polarization in which inflammatory M1 phenotype dominates over the anti-inflammatory M2 phenotype. Hence, it is essential to identify a specific target, which could revert the metabolic profile and thereby reducing the M1 macrophage polarization. 14-3-3η protein has several cellular protective functions especially in the heart as plenty of reports available in various animal models of heart failure including diabetes mellitus...

BACKGROUND: Diastolic dysfunction (DD), a hallmark of obesity and primary defect in heart failure with preserved ejection fraction, is a predictor of future cardiovascular events. We previously reported that linagliptin, a dipeptidyl peptidase-4 inhibitor, improved DD in Zucker Obese rats, a genetic model of obesity and hypertension. Here we investigated the cardioprotective effects of linagliptin on development of DD in western diet (WD)-fed mice, a clinically relevant model of overnutrition and activation of the renin-angiotensin-aldosterone system...

BACKGROUND: Missing preadmission serum creatinine (SCr) values are a common obstacle to assess acute kidney injury (AKI) diagnosis and outcomes. The Kidney Disease Improving Global Outcomes (KDIGO) guidelines suggest using a SCr computed from the Modification of Diet in Renal Disease (MDRD) with an estimated glomerular filtration rate of 75 ml/min/1.73 m(2). We aimed to identify the best surrogate method for baseline SCr to assess AKI diagnosis and outcomes. METHODS: We compared the use of 1) first SCr at hospital admission 2) minimal SCr over 2 weeks after intensive care unit admission 3) MDRD computed SCr and 4) Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) computed SCr to assess AKI diagnosis and outcomes...

BACKGROUND: Hypertension is a major cause of heart failure. Excessive sympathoexcitation in patients with heart failure leads to poor prognosis. Since carotid body denervation (CBD) has been shown to reduce sympathetic nerve activity in animal models of hypertension and heart failure, we examined if bilateral CBD attenuates the progression of hypertensive heart failure and improves survival. METHODS: We randomly allocated Dahl salt-sensitive rats fed a high-salt diet from 6 weeks of age into CBD (n = 31) and sham-operation (SHAM; n = 50) groups, and conducted CBD or SHAM at 7 weeks of age...

BACKGROUND AND AIMS: Anthracyclines are effective anticancer drugs that have improved prognosis of hundred thousand cancer patients worldwide and are currently the most common chemotherapeutic agents used for the treatment of blood, breast, ovarian and lung cancers. However, their use is limited because of a cumulative dose-dependent and irreversible cardiotoxicity that can cause progressive cardiomyopathy and congestive heart failure. Aim of the present study was to determine the cardioprotective activity of a dietary source of cyanidin 3-glucoside (C3G), such as purple corn, against doxorubicin (DOX)-induced cardiotoxicity in mice...
