Ductus arteriosus (DA) is a crucial element in the fetal circulation. Therefore, premature constriction of DA during the third trimester can have hazardous complications such as right ventricular dysfunction, fetal heart failure, hydrops, and even in utero demise. Normally, premature constriction is prevented by a balance between prostaglandin E2 and fetal oxygenation. Thus, drugs with antiprostaglandin effects are well-known causes for fetal DA constriction. A similar effect was discovered in eating polyphenol-rich food...

Diabetic patients are at an increased risk of developing heart failure when compared to their non-diabetic counter parts. Accumulative evidence suggests chronic hyperglycemia to be central in the development of myocardial infarction in these patients. At present, there are limited therapies aimed at specifically protecting the diabetic heart at risk from hyperglycemia-induced injury. Oxidative stress, through over production of free radical species, has been hypothesized to alter mitochondrial function and abnormally augment the activity of the NADPH oxidase enzyme system resulting in accelerated myocardial injury within a diabetic state...

BACKGROUND: Protein kinase G (PKG) Iα is the end-effector kinase that mediates nitric oxide (NO)-dependent and oxidant-dependent vasorelaxation to maintain blood pressure during health. A hallmark of cardiovascular disease is attenuated NO production, which in part is caused by NO Synthase (NOS) uncoupling, which in turn increases oxidative stress because of superoxide generation. NOS uncoupling promotes PKG Iα oxidation to the interprotein disulfide state, likely mediated by superoxide-derived hydrogen peroxide, and because the NO-cyclic guanosine monophosphate (cGMP) pathway otherwise negatively regulates oxidation of the kinase to its active disulfide dimeric state...

BACKGROUND: Pulmonary hypertension (PH), caused by elevated pulmonary vascular resistance, leads to right heart failure and ultimately death. Vitamin D deficiency can predispose individuals to hypertension and left ventricular dysfunction; however, it remains unknown how serum vitamin D level is related to PH and right ventricular (RV) dysfunction. METHODS: Serum 25-hydroxyvitamin D [25(OH)D] levels were assessed in PH patients for an association with disease severity...

OBJECTIVE: Calcific aortic valve disease (CAVD) is currently the most common heart valve disease worldwide and is known to be an active process. Both renal failure and dyslipidaemia are considered to be promoting factors for the development of valvular calcifications. The aim of this study is to prospectively evaluate the respective contribution and interaction of renal failure and dyslipidaemia on CAVD in a rat model, using echocardiography and compared with histology. METHODS AND RESULTS: Sixty-eight male Wistar rats were prospectively divided in eight groups, each fed a different diet to induce renal failure alone and combined with hyperlipidaemia or hypercholesterolemia...

BACKGROUND: The American Heart Association introduced the Life's Simple 7 (LS7) metrics to assess and promote cardiovascular health. We sought to examine the association between the LS7 metrics and incident heart failure (HF) in a multiethnic cohort. METHODS AND RESULTS: We analyzed data from 6506 participants of the Multi-Ethnic Study of Atherosclerosis free of cardiovascular disease at baseline. The LS7 metrics (smoking, physical activity, body mass index, diet, blood pressure, total cholesterol, and blood glucose) were graded on a scale of 0 to 2, with 2 indicating "ideal" status, 1 "intermediate" status, and 0 "poor" status...

BACKGROUND: Heart failure (HF) is associated with chronic sympathetic activation. Renal denervation (RDN) aims to reduce sympathetic activity by ablating the renal sympathetic nerves. We investigated the effect of RDN in patients with chronic HF and concurrent renal dysfunction, in a prospective, multicenter, single-arm feasibility study. METHODS AND RESULTS: Thirty-nine patients with chronic systolic HF (left ventricular ejection fraction [LVEF] <40%, New York Heart Association class II-III,) and renal impairment (estimated glomerular filtration rate [eGFR; assessed with Modification of Diet in Renal Disease equation] <75 mL/min/1...

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: Estrogen loss has been implicated to increase the risk of alcoholic cardiomyopathy in postmenopausal women. The purpose of this study was to identify novel mitochondrial protein targets for the treatment of alcoholic cardiomyopathy in aged women using a state-of-the-art proteomic approach. We hypothesized that chronic ethanol (EtOH) ingestion exacerbates maladaptive mitochondrial protein expression in the aged female heart. METHODS: Adult (3 months) and aged (18 months) F344 ovary-intact or ovariectomized (OVX) rats were randomly assigned an EtOH or control Lieber-DeCarli "all-liquid" diet for 20 weeks...

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...
