BACKGROUND: Riociguat, the first approved drug for patients with chronic thromboembolic pulmonary hypertension (CTEPH), is a soluble guanylate cyclase (sGC) Stimulator. It directly stimulates sGC independently of nitric oxide (NO) and increases sGC sensitivity for NO. The safety and efficacy of transitioning from a phosphodiesterase 5 inhibitor (PDE5i) to riociguat is unknown. METHODS AND RESULTS: Twenty-three patients were prospectively enrolled: 8 symptomatic patients with inadequate clinical responses to PDE5i were changed to riociguat (transitioned group); 15 started riociguat anew (new or add-on group)...

BACKGROUND: Aortic stiffening and reduced nitric oxide (NO) availability may contribute to the pathophysiology of heart failure with preserved ejection fraction (HFpEF). OBJECTIVES: This study compared indices of arterial stiffness at rest and during exercise in subjects with HFpEF and hypertensive control subjects to examine their relationships to cardiac hemodynamics and determine whether exertional arterial stiffening can be mitigated by inorganic nitrite. METHODS: A total of 22 hypertensive control subjects and 98 HFpEF subjects underwent hemodynamic exercise testing with simultaneous expired gas analysis to measure oxygen consumption...

OBJECTIVE: Inhaled nitric oxide (iNO) is commonly used as a treatment of pulmonary hypertension. Its action is purported to be specific to the lung, but extrapulmonary effects have been reported. The objective of this study was to evaluate if iNO could compensate the renal impairment induced by ketoprofen, a conventional non-steroidal anti-inflammatory drug (NSAID), during general anaesthesia. METHODS: Under pseudo-normovolaemic condition, thirty piglets were randomly assigned into 5 equal groups and equipped for renal and systemic parameters measurements...

Leticia Figueira, Anita Israel
Adrenomedullin (AM) is a peptide involved in blood pressure regulation. AM activates three different receptors, the AM type 1 (AM1), type 2 (AM2), and calcitonin gene-related peptide 1 (CGRP1) receptors. AM triggers several signaling pathways such as adenylyl cyclase (AC), guanylyl cyclase (GC), and extracellular signal-regulated kinases (ERK) and modulates reactive oxygen species (ROS) metabolism. Cerebellar AM, AM-binding sites, and its receptor components are altered during hypertension, although it is unknown if these alterations are associated with changes in AM signaling...

Hypertension is associated with enhanced vascular oxidative stress and impaired endothelial function, which is related to an imbalance between reactive oxygen species and nitric oxide bioavailability. Short-term supplementation with a polyphenol-rich powdered red wine pomace seasoning (RWPS) was investigated for its effects on blood pressure and biomarkers of endothelial dysfunction and oxidative status in a model of essential hypertension. Male spontaneously hypertensive rats (SHRs) and normotensive Wistar-Kyoto rats (12-week-old, 5 rats per group) were administered RWPS (300 mg kg(-1) day(-1); equivalent to 7...

Polychlorinated biphenyls (PCBs) have been reported to be associated with increased risk to hypertension, atherosclerosis, cardiovascular disease, etc. 2,3',4,4',5-Pentachlorobiphenyl, known as PCB-118, is a member of coplanar PCBs which renders their structure similar to polychlorinated dibenzo-p-dioxins (PCDDs) and has dioxin-like activity. In our current study, we investigated the effect of PCB-118 exposure on nitric oxide (NO) production and the underlying mechanisms in vitro. Exposure of PCB-118 impaired insulin-induced NO production and endothelial nitric oxide synthase (eNOS) activity in human umbilical vein endothelial cells (HUVECs) with no significant effect on cell viability...

Chronic inflammatory state in obesity causes dysregulation of the endocrine and paracrine actions of adipocyte-derived factors, which disrupt vascular homeostasis and contribute to endothelial vasodilator dysfunction and subsequent hypertension. While normal healthy perivascular adipose tissue (PVAT) ensures the dilation of blood vessels, obesity-associated PVAT leads to a change in profile of the released adipo-cytokines, resulting in a decreased vasorelaxing effect. Adipose tissue inflammation, nitric oxide (NO)-bioavailability, insulin resistance and oxidized low-density lipoprotein (oxLDL) are main participating factors in endothelial dysfunction of obesity...

Reactive oxygen species (ROS) are reactive intermediates of molecular oxygen that act as important second messengers within the cells; however, an imbalance between generation of reactive ROS and antioxidant defense systems represents the primary cause of endothelial dysfunction, leading to vascular damage in both metabolic and atherosclerotic diseases. Endothelial activation is the first alteration observed, and is characterized by an abnormal pro-inflammatory and pro-thrombotic phenotype of the endothelial cells lining the lumen of blood vessels...

Obesity-associated hypertension is accompanied by a number of cardiovascular risk factors including vascular insulin resistance (IR) and higher sympathetic nervous activity. Therefore, autonomic blockade was demonstrated to reverse hypertension, endothelial dysfunction and IR in obese individuals. We hypothesized that β-AR blockade with propranolol would restore endothelial function and vascular insulin signaling in obesity, associated with an anti-inflammatory effect. Body weight, systolic blood pressure (SBP), plasma biochemical parameters and aortic endothelial function were analyzed in mice fed standard diet (control group) or a high fat diet (HFD) that were treated with vehicle (water) or propranolol (10mg/kg/day) for 8weeks...

Cardiac neuronal nitric oxide synthase (nNOS) is an important molecule that regulates intracellular Ca(2+) homeostasis and contractility of healthy and diseased hearts. Here, we examined the effects of nNOS on fatty acid (FA) regulation of left ventricular (LV) myocyte contraction in sham and angiotensin II (Ang II)-induced hypertensive (HTN) rats. Our results showed that palmitic acid (PA, 100 μM) increased the amplitudes of sarcomere shortening and intracellular ATP in sham but not in HTN despite oxygen consumption rate (OCR) was increased by PA in both groups...

Persistent pulmonary hypertension of the newborn (PPHN) represents a challenging condition associated with significant morbidity. A successful transition from intrauterine to extrauterine life is contingent on adequate pulmonary vasodilation. Several pathophysiologies contribute to the failure of this cascade and may result in life-threatening hypoxia and acidosis in the newborn. Management includes optimal respiratory support, adequate sedation and analgesia, and support of vascular tone and cardiac function...

S-palmitoylation is an important post-translational modification that affects the translocation and the activity of target proteins in a variety of cell types including cardiomyocytes. Since endothelial nitric oxide synthase (eNOS) is known to be palmitoylated and the activity of eNOS is essential in fatty acid-dependent β-oxidation in muscle, we aimed to test whether palmitoylation of eNOS is involved in palmitic acid (PA) regulation of left ventricular (LV) myocyte contraction from healthy (sham) and hypertensive (HTN) rats...

Reactive oxygen and nitrogen species (ROS and RNS, e.g. H2O2, nitric oxide) confer redox regulation of essential cellular signaling pathways such as cell differentiation, proliferation, migration and apoptosis. At higher concentrations, ROS and RNS lead to oxidative stress and oxidative damage of biomolecules (e.g. via formation of peroxynitrite, fenton chemistry). Peripheral artery disease (PAD) is characterized by severe ischemic conditions in the periphery leading to intermittent claudication and critical limb ischemia (end stage)...
