An important challenge in the management of patients with type 2 diabetes is cardiovascular disease (CVD) prevention. While it is well established that intensive glycemic control prevents the onset and slows the progression of certain microvascular complications, such a strategy utilized in multiple clinical trials over the past few decades has failed to show a similar benefit with regard to cardiovascular events, including mortality. Despite this, a major hope has been the discovery of glucose-lowering medications that simultaneously improve cardiovascular outcomes...

High dietary salt intake may lead to vascular stiffness, which predicts cardiovascular diseases such as heart failure, and myocardial and cerebral infarctions as well as renal impairment. The vascular endothelium is a primary target for deleterious salt effects leading to dysfunction and endothelial stiffness. We hypothesize that the Ca(2+)- and bicarbonate-activated soluble adenylyl cyclase (sAC) contributes to Na(+)/K(+)-ATPase expression regulation in vascular endothelial cells and is an important regulator of endothelial stiffness...

BACKGROUND: Patients having coronary artery disease treated by coronary bypass or PCI procedure are exposed to tissue damage because of the phenomenon called reperfusion injury. Reperfusion injury can be characterized/monitored by oxidative stress parameters, inflammatory markers and by post-operative complication rate. OBJECTIVE: Beyond the obvious factors determining its severity (affected myocardial mass, ischaemic time, collateral circulation etc.) we examined the GST enzyme group's most cardio selective member, GSTP1 and its genetic polymorphism if there is any genetically determined preventive effect on the above-mentioned parameters...

Dietary phenolic compounds (PCs) have been receiving interest for their presumed roles in disease prevention. However, there is a lack of studies on the underlying molecular mechanisms. In this regard, in vitro metabolomic approaches are suitable for the investigation of the molecular changes in response to PC exposure. Up to date, the biological effects of PCs have only been examined for PCs from rosemary (Rosmarinus officinalis), olive oil, and resveratrol using cell-based metabolomic approach, although transcriptomic and/or proteomic studies have also been conducted in the same in vitro cell experiment in some cases...

Increased sympathetic nerve activity and the activation of the central renin-angiotensin system are commonly associated with cardiovascular disease states such as hypertension and heart failure, yet the precise mechanisms contributing to the long-term maintenance of this sympatho-excitation are incompletely understood. Due to the established physiological role of neurotrophins contributing toward neuroplasticity and neuronal excitability along with recent evidence linking the renin-angiotensin system and brain-derived neurotrophic factor (BDNF) along with its receptor (TrkB), it is likely the two systems interact to promote sympatho-excitation during cardiovascular disease...

INTRODUCTION: Proprotein convertase subtilisin/kexin type 9 (PCSK9) plays an important role in the modulation of plasma levels of low density lipoprotein cholesterol (LDLC). PCSK9 binds to the LDL receptor (LDLR), disrupts its endocytic recycling itinerary and directs it to lysosomal degradation. Activation of PCSK9 can thus decrease the expression of LDLR in the liver and inhibit LDL uptake, which leads to hypercholesterolaemia. DEVELOPMENT: Currently we now know that different polymorphisms of PCSK9 are associated with the occurrence of ischaemic stroke...

Obesity has become a worldwide epidemic, and its prevalence has been projected to grow by 40% in the next decade. This increasing prevalence has implications for the risk of diabetes, cardiovascular disease and also for Chronic kidney disease. A high body mass index is one of the strongest risk factors for new-onset Chronic kidney disease. In individuals affected by obesity, a compensatory hyperfiltration occurs to meet the heightened metabolic demands of the increased body weight. The increase in intraglomerular pressure can damage the kidneys and raise the risk of developing Chronic kidney disease in the long-term...

Reactive oxygen species (ROS) are produced under normal physiological conditions and involved in several cellular biochemical processes. Their external or endogenous overproduction induces a disruption of redox signaling and control known as oxidative stress. Under oxidative stress, the cell membrane structures, enzyme functions and gene expression are compromised leading to the pathogenesis of several chronic inflammatory diseases including the cardiovascular pathologies. Attempts to find new therapeutic molecules capable of blocking the oxidative stress are of crucial importance...

The advances in healthcare over the past several decades have resulted in populations now living longer. With this increase in longevity, a wider prevalence of cardiovascular diseases is more common and known to be a major factor in rising healthcare costs. A wealth of scientific evidence has implicated cell senescence as an important component in the etiology of these age-dependent pathologies. A number of studies indicate that an excess of reactive oxygen species (ROS) contributes to trigger and accelerate the cardiac senescence processes, and a new role of monoamine oxidases, MAO-A and MAO-B, is emerging in this context...

Aging is associated with significant changes in both cardiac and vascular structure and function that lower the threshold for clinical signs and symptoms, making older people more susceptible to cardiovascular diseases, morbidity and mortality. Understanding of age-related cardiovascular changes is necessary for effective and efficient prevention and treatment of cardiovascular disease in older people. Cardiac aging is associated with left ventricular remodelling marked by increased mass-to-volume ratio and accompanied by systolic and diastolic myocardial dysfunction, and reduced sensitivity to sympathetic stimuli that compromises myocardial contractility and pumping ability in older people...

BACKGROUND: Recent clinical trials highlight the need for better models to identify patients at higher risk of sudden death. OBJECTIVES: The authors hypothesized that the Seattle Heart Failure Model (SHFM) for overall survival and the Seattle Proportional Risk Model (SPRM) for proportional risk of sudden death, including death from ventricular arrhythmias, would predict the survival benefit with an implantable cardioverter-defibrillator (ICD). METHODS: Patients with primary prevention ICDs from the National Cardiovascular Data Registry (NCDR) were compared with control patients with heart failure (HF) without ICDs with respect to 5-year survival using multivariable Cox proportional hazards regression...

Sleep-disordered breathing (SDB) is a highly prevalent condition, and is associated with many debilitating chronic diseases. The role of untreated obstructive sleep apnea (OSA) in arterial hypertension has been recognized in international guidelines. Treatment with continuous positive airway pressure (CPAP) is associated with clinically-relevant reductions in blood pressure. In heart failure (HF), SDB is associated with worse prognosis and increased mortality. Major HF guidelines recommend that patients should be treated for sleep apnea to improve their HF status...
