In recent years great emphasis has been placed on the role of central aortic blood pressure as measured non invasively using pulse wave analysis in pathophysiology of cardiovascular diseases and clinical aspects of hypertension. The difference of blood pressure between the central aorta and the brachial artery (amplification) is not constant but varies according to physiological, pathological and pharmacological mechanisms. Central aortic blood pressure is more strongly related to cardiovascular organ damages than does brachial pressure...

Cardiovascular diseases (CVDs) have a high prevalence and annually increasing incidence with high mortality and morbidity. Identification of biomarkers with high sensitivity and specificity for assessing the prognosis of CVDs is necessary for optimizing personalized treatment and reducing mortality. Exosomes have been proved to be accessible in nearly all body fluids and they can reflect disease stage or progression. Here we summarized exosomes-based biomarkers for the prognosis of coronary artery diseases, heart failure, stroke, hypertension, cardiac arrhythmia, cardiomyopathy, valvular heart diseases and pulmonary arterial hypertension...

Pulmonary arterio-venous malformations (PAVMs) are abnormal pulmonary arteries and pulmonary veins communicating directly without interposition of a capillary bed and about 80-90% of patients with PAVMs eventually may present with hereditary hemorrhagic telangiectasia (HHT), remaining ones are sporadic cases. On the other hand, about 15-35% of HHT patients may present with PAVMs. The PAVMs have a tendency to grow and increase in size over time and various factors like puberty, pregnancy and pulmonary arterial hypertension (PAH) affect growth...

A non-dipper pattern of high blood pressure is associated with increased risk of organ damage and cardiovascular disease in patients with hypertension. The aim of the study was to evaluate the left ventricular (LV) remodeling and function and arterial stiffness in a dipper/non-dipper pattern of high blood pressure in patients with hypertension. A total of 183 hypertensive patients with no history of adverse cardiovascular events were divided into two groups based on 24 hours ambulatory blood pressure monitoring (ABPM): 66 patients with a dipper pattern and 117 patients with non-dipper pattern...

Pulmonary hypertension in left heart disease (PH-LHD) commonly complicates prolonged heart failure (HF). When advanced, the PH becomes fixed or out of proportion and is associated with increased morbidity and mortality in patients undergoing orthotopic heart transplant (OHT). To date, the only recommended treatment of out of proportion PH is the treatment of the underlying HF by reducing the pulmonary capillary wedge pressure (PCWP) with medications and often along with use of mechanical circulatory support...

Recent studies have demonstrated that stromal derived factor-1α (SDF-1α) is a substrate of dipeptidyl-peptidase-4 (DPP-4) inhibitors. It has also been shown that SDF-1α shares anti-apoptotic as well as nephroprotective properties and exerts a beneficial effect in the cardiovascular system. Therefore, the aim of this study was to estimate the effect of treatment with the DDP-4 inhibitor sitagliptin on SDF-1α levels in subjects with type 2 diabetes mellitus (T2D). Overall, 32 patients (16 males) with T2D, mean age (±SD) 67...

BACKGROUND: The early impact of renal transplantation on subclinical cardiovascular measures in pediatric patients has not been widely investigated. This analysis is performed for pediatric patients participating in the prospective 4C study and focuses on the early effects of RRT modality on cardiovascular comorbidity in patients receiving a preemptive transplant or started on dialysis. METHODS: We compared measures indicating subclinical cardiovascular organ damage (aortal pulse wave velocity, carotid intima media thickness, left ventricular mass index) and evaluated cardiovascular risk factors in 166 pediatric patients before and 6 to 18 months after start of RRT (n=76 transplantation, n=90 dialysis)...

Pulmonary artery hypertension (PAH) is characterized by structural changes in pulmonary arteries. Increased numbers of cells expressing α-smooth muscle actin (α-SMA) is a nearly universal finding in the remodeled artery. It has been confirmed endothelial-to-mesenchymal transition (EndoMT) may be a source of those α-SMA-expressing cells. In addition, the EndoMT is reversible. Here, we show that under hypoxia, the expression of bone morphogenetic protein 7 (BMP-7) was decreased both in vivo and in vitro. We also found that under normoxia, BMP-7 deficiency induced spontaneous EndoMT and cell migration...

Atrial fibrillation (AF) is the most common cardiac arrhythmia that occurs because of several different risk factors, e.g., valvular heart disease, coronary artery disease, age ≥75 years, hypertension and diabetes mellitus. One key risk factor that results in AF, is oxidative stress. Evidence suggests that there is a correlation between oxidative processes and the genesis of AF. Oxidative stress occurs when the generation of reactive oxygen species (ROS) increase due to excessive activity of enzymes including NADPH oxidase (NOX) and xanthine oxidase; or its degradation decrease by dysfunctional antioxidant enzyme systems, such as superoxide dismutase (SOD), catalase and glutathione peroxidase (GPx)...

INTRODUCTION:  The over-the-scope-clip (OTSC) can potentially overcome limitations of standard clips and achieve more efficient and reliable hemostasis. Data on OTSC use for non-variceal upper gastrointestinal bleeding (NVUGIB) in patients with cardiovascular comorbidities are currently limited. PATIENTS AND METHODS:  We prospectively collected and retrospectively analyzed our database from February 2009 to September 2015 from all patients who underwent emergency endoscopy for high-risk NVUGIB in 2 academic centers and were treated with OTSC as first-line (n = 81) or second-line therapy (n = 19)...

The endothelial-to-mesenchymal transition (EndMT) has been demonstrated to be involved in pulmonary vascular remodeling. It is partly attributed to oxidative and inflammatory stresses in endothelial cells. In current study, we conducted a series of experiments to clarify the effect of salvianolic acid A (SAA), a kind of polyphenol compound, in the process of EndMT in human pulmonary arterial endothelial cells and in vivo therapeutic efficacy on vascular remodeling in monocrotaline (MCT)-induced EndMT. EndMT was induced by TGFβ1 in human pulmonary arterial endothelial cells (HPAECs)...

Pulmonary arterial hypertension (PAH) is a rare disease resulting in progressive remodeling of the pulmonary vasculature and eventual right ventricular failure. Despite the development of 13 therapies for PAH since 2000, the use of continuously infused prostanoids retains a special role. Infused medications present unique challenges, and the search for an efficacious oral prostanoid culminated in the FDA approval of oral treprostinil - a first in class oral prostanoid medication approved to treat pulmonary arterial hypertension (PAH)...

BACKGROUND: Macitentan is beneficial for long-term treatment of pulmonary arterial hypertension. The microvasculopathy of chronic thromboembolic pulmonary hypertension (CTEPH) and pulmonary arterial hypertension are similar. METHODS: The phase 2, double-blind, randomised, placebo-controlled MERIT-1 trial assessed macitentan in 80 patients with CTEPH adjudicated as inoperable. Patients identified as WHO functional class II-IV with a pulmonary vascular resistance (PVR) of at least 400 dyn·s/cm(5) and a walk distance of 150-450 m in 6 min were randomly assigned (1:1), via an interactive voice/web response system, to receive oral macitentan (10 mg once a day) or placebo...

In the United States, up to 450,000 people per year die suddenly; an average of 1 sudden death every 70s. Strategies for preventing sudden cardiac death are urgently needed. Systemic arterial hypertension is a major risk factor for sudden cardiac death and the increasing burden of hypertension is a worldwide problem. The lifetime risk of sudden cardiac death at 30years of age is higher by 30% in individuals with hypertension. Each 20/10mmHg increase in systolic/diastolic blood pressure, is associated with a 20% additional increase in sudden cardiac death risk...

Retinal venous occlusions comprise central retinal vein occlusion, hemiretinal vein occlusions, and branch retinal vein occlusions. They are associated with arterial hypertension and glaucoma. Retinal vein occlusions occur more frequently in males, at a median age of 55. The pathogenesis of retinal venous occlusions remains obscure. The clinical presentation of the disease is variable. In most cases, there is a unilateral visual loss over days with a painless, white and quiet eye. However, retinal venous occlusions may also present as an abrupt and profound loss of vision, or be asymptomatic...

The potential protective role of the standardized leaf extract of ginkgo biloba (EGb761) on hypertension with hypercholesterolemia-induced renal injury was investigated in rats. Hypertension was induced by L-N(G)-nitroarginine methyl ester (L-NAME) and hypercholesterolemia was induced by feeding rats with a diet containing 1% cholesterol. In these animals repeated treatment with EGb761 produced a progressive reduction in the systolic, diastolic and mean arterial blood pressure (BP). EGb761 increased the progressive reduction in the systolic, diastolic and mean arterial BP induced by repeated administration of losartan with simvastatin...
