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...

Telomeres are repetitive nucleoprotein structures at chromosome ends and a decrease in the number of these repeats, known as a reduction in telomere length (TL), triggers cellular senescence and apoptosis. Heart disease, the worldwide leading cause of death, often results from the loss of cardiac cells which could be explained by decreases in TL. Due to the cell-specific regulation of TL, this review focuses on studies that have measured telomeres in heart cells and critically assesses the relationship between cardiac TL and heart function...

ETHNOPHARMACOLOGICAL RELEVANCE: Radix paeoniae rubra, also known as chishao (CS), is a frequently used traditional Chinese medicine that can promote blood circulation to remove blood stasis. It has been widely used for the prevention and treatment of cardiovascular diseases in China. Although terpene glycoside (TG), the major component in CS, has been shown to possess cardioprotective properties, the mechanism underlying CS-TG's preventive effect against myocardial ischemia injury is unknown...

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...

With new surgical techniques, more and more complex congenital heart defects are treated requiring sometimes right ventricle to pulmonary artery conduit implantation. In order to extend RV to PA conduit lifespan, 15 years ago a valved stent was developed. The implantation technique was progressively standardized to decrease risks of procedural complications. Medium and long-term hemodynamic results of the stent were so good that indications were broadened to native or complex right ventricular outflow tracts...

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...

Pediatric lung transplant is a viable option for treatment of end-stage lung disease in children, with > 100 pediatric lung transplants reported to the Registry of the International Society of Heart and Lung Transplantation each year. Long-term success is limited by availability of donor organs, debilitation as a result of chronic disease, impaired mucus clearance resulting from both surgical and pharmacologic interventions, increased risk for infection resulting from immunosuppression, and most importantly late complications, such as chronic lung allograft dysfunction...

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...

Women with a history of preeclampsia have increased risk of cardiovascular disease later in life. However, it is unclear if early gestational age at preeclampsia onset is associated with higher cardiovascular disease risk. This study aimed to test the association between gestational age at preeclampsia onset (including the early-onset/late-onset preeclampsia distinction) and subclinical atherosclerosis and arterial stiffness in age-matched women 12 years after index pregnancy MATERIAL AND METHODS: Eligible participants were identified in two Danish registries...

Understanding the cellular-molecular substrates of heart disease is key to the development of cardiac specific therapies and to the prevention of off-target effects by non-cardiac targeted drugs. One of the primary targets for therapeutic intervention has been the human ether a go-go (hERG) K+ channel that, together with the KCNQ channel, controls the rate and efficiency of repolarization in human myocardial cells. Neither of these channels plays a major role in adult mouse heart function; however, we show here that the hERG homolog seizure (sei), along with KCNQ, both contribute significantly to adult heart function as they do in humans...

Hypertension (HTN) is a common cardiovascular risk factor leading to heart failure (HF), coronary artery disease (CAD), stroke, peripheral artery disease and chronic renal failure. Hypertensive heart disease can manifest as many types of cardiac arrhythmias, most commonly being atrial fibrillation (AF). Both supraventricular and ventricular arrhythmias may occur in HTN patients, especially in those with left ventricular hypertrophy (LVH), CAD or HF. In addition, high doses of thiazide diuretics commonly used to treat hypertension, may result in electrolyte abnormalities (eg...

INTRODUCTION: Pulmonary embolism (PE) is a life threatening preventable medical condition involving sudden occlusion of arteries within the lungs. Systemic lupus erythematosus (SLE) is an inflammatory disorder and therefore independently poses a risk of PE. We aimed to determine the association of SLE and PE using National Hospital Discharge Survey data, a national representative sample of hospital discharges throughout the United States. METHODS: Retrospective population-based analysis was done using National Hospital Discharge Survey data for the period 2001 to 2010...

The optimal treatment approach to patients with coronary artery disease (CAD), including those with type 2 diabetes mellitus (T2DM), has been extensively evaluated. Several trials of stable ischemic heart disease including patients with T2DM have demonstrated that medical management is comparable to revascularization in terms of mortality and rates of major adverse cardiovascular events (MACE). There has been a growing appreciation for optimal medical therapy's (OMT) role in improving clinical outcomes. It is vital to target T2DM patients to prevent or delay MACE events through advanced OMT, ultimately delaying if not avoiding the need for revascularization...

Hypertension is among the leading risk factors for cardiovascular disease and accounts for 6% of adult deaths worldwide. It is estimated that in 2013, hypertension was responsible for at least 45% of deaths due to heart disease and 51% of deaths due to stroke. Accordingly, management of hypertension and its long-term complications in HIV-infected subjects is a significant component of routine care. The choice of an effective anti-hypertensive therapy in HIV-infected patients is important and must be made carefully in order to prevent cardiovascular mortality and morbidity in these patients...
