Pulmonary hypertension (PH) is a rare, but life-threatening, adverse event in patients treated with tyrosine kinase inhibitors (TKIs), such as dasatinib, but has not been fully evaluated in patients treated with imatinib or nilotinib. We used echocardiography to noninvasively assess the incidence of PH in 105 patients with chronic myeloid leukaemia (CML) treated with imatinib (n = 37), nilotinib (n = 30) or dasatinib (n = 38). The mean triscupid regurgitation peak gradient (TRPG), which reflects pulmonary arterial pressure, was 22·7 mmHg in the imatinib group, 23·1 mmHg in the nilotinib group and 23·4 mmHg for dasatinib group...

In patients with end-stage renal disease (ESRD) treated with haemodialysis or peritoneal dialysis, hypertension is common and often poorly controlled. Blood pressure (BP) recordings obtained before or after haemodialysis display a J- or U-shaped association with cardiovascular events and survival, but this most likely reflects the low accuracy of these measurements and the peculiar haemodynamic setting related to dialysis treatment. Elevated BP detected by home or ambulatory BP monitoring is clearly associated with shorter survival...

Vascular remodeling during chronic hypertension may impair the supply of tissues with oxygen, glucose and other compounds, potentially unleashing deleterious effects. In this study, we used Spontaneously Hypertensive Rats and normotensive Wistar-Kyoto rats with or without pharmacological inhibition of poly(ADP-ribose)polymerase-1 by an experimental compound L-2286, to evaluate carotid artery remodeling and consequent damage of neuronal tissue during hypertension. We observed elevated oxidative stress and profound thickening of the vascular wall with fibrotic tissue accumulation induced by elevated blood pressure...

BACKGROUND: Arterial function is regulated by estrogen, but no consistent pattern of arterial mechanical remodeling in response to depleted estrogen levels is available. OBJECTIVE: To examine long-term effects of ovariectomy (OVX) on the mechanical properties, morphology, and histological structure of carotid artery in middle-aged rats and a potentially protective effect of Sideritis euboea extract (SID), commonly consumed as "mountain tea". METHODS: 10-month-old female Wistar rats were allocated into control (sham-operated), OVX, OVX+SID, and OVX+MALT (maltodextrin; excipient used for dilution of SID) groups...

Perivascular spaces that are visible on magnetic resonance imaging (MRI) are a neuroimaging marker of cerebral small vessel disease. Their location may relate to the type of underlying small vessel pathology: those in the white matter centrum semi-ovale have been associated with cerebral amyloid angiopathy, while those in the basal ganglia have been associated with deep perforating artery arteriolosclerosis. As cerebral amyloid angiopathy is an almost invariable pathological finding in Alzheimer's disease, we hypothesized that MRI-visible perivascular spaces in the centrum semi-ovale would be associated with a clinical diagnosis of Alzheimer's disease, whereas those in the basal ganglia would be associated with subcortical vascular cognitive impairment...

Vascular tone of resistance arteries and arterioles determines peripheral vascular resistance, contributing to the regulation of blood pressure and blood flow to, and within the body's tissues and organs. Ion channels in the plasma membrane and endoplasmic reticulum of vascular smooth muscle cells (SMCs) in these blood vessels importantly contribute to the regulation of intracellular Ca2+ concentration, the primary determinant of SMC contractile activity and vascular tone. Ion channels provide the main source of activator Ca2+ that determines vascular tone, and strongly contribute to setting and regulating membrane potential, which, in turn, regulates the open-state-probability of voltage gated Ca2+ channels (VGCCs), the primary source of Ca2+ in resistance artery and arteriolar SMCs...

The objective of this review is to provide an in-depth evaluation of how renal nerves regulate renal and cardiovascular function with a focus on long-term control of arterial pressure. We begin by reviewing the anatomy of renal nerves and then briefly discuss how the activity of renal nerves affects renal function. Current methods for measurement and quantification of efferent renal-nerve activity (ERNA) in animals and humans are discussed. Acute regulation of ERNA by classical neural reflexes as well and hormonal inputs to the brain is reviewed...

Postmenopausal women are at increased risk for progression of arteriosclerosis and hypertension. Recent cross-sectional evidence suggests that high normal circulating prolactin levels may accelerate vascular ageing in menopause. Postmenopausal women (n=201) were consecutively recruited from a Menopause Clinic and re-evaluated in at least one follow-up visit within the next 3 years. Baseline circulating prolactin levels were measured while both baseline and follow-up vascular and biochemical measurements were performed...

PURPOSE: Pulmonary arterial hypertension (PAH) is a fatal disease which is characterized by an increase in pulmonary arterial pressure leading to increases in right ventricular afterload. Human umbilical cord blood derived-mesenchymal stem cells (hUCB-MSCs) administered via the jugular vein have been previously shown to improve PAH by reversal treatment. However, the effect of low dosage and transfusion timing of hUCB-MSCs on PAH has not yet been clearly established. Obviously, low dosage treatment can lead to a reduction in costs...

Extracardiac arterial stenoses are not uncommon in Williams syndrome (WS); however, data on the utility of advanced cardiovascular imaging (CVI) to assess these stenoses are lacking. We retrospectively reviewed the frequency, indication, and diagnostic outcomes of CVI modalities performed in patients with WS evaluated at a single institution between 2001 and 2014. Data were collected and analyzed from 34 patients (56% female) who underwent CVI during the study period. The median age was 10 years (range 1.8-33 years)...

BACKGROUND: Elevated homocysteine (Hc) levels have a well-established and clear causal relationship to epithelial damage leading to coronary artery disease. Furthermore, it is strongly associated with other metabolic syndrome variables, such as hypertension, which is correlated with type II diabetes mellitus (T2DM). Studies on T2DM in relation to Hc levels have shown both positive and negative associations. The aim of the present study is to examine the relationship between Hc levels and risk of T2DM in the Lebanese population...

BACKGROUND: In cases of chronic thromboembolic pulmonary hypertension (CTEPH), referral for possible surgical intervention is important because surgery can be curative. Surgery necessitates cardiopulmonary bypass and deep circulatory arrest with pulmonary thrombectomy and bilateral endarterectomy (PTE). If surgery fails, lung transplant is the next best surgical option. Medical treatment is also an important adjunct. CASE REPORT: A 35-year-old female presented 3 months after a pulmonary embolus was found to be completely occluding her left pulmonary artery...

The main risk factors in ischemic heart diseases, including myocardial infarction, are hypertension, dyslipidemia, diabetes, obesity and smoking. The incidence of ischemic heart disease in Japan has been lower than that in Western countries because of differences in lifestyle and the anatomy of the coronary arteries, but the situation has been changing recently because of the westernization of lifestyle. Cardiovascular diseases have become the second most common cause of death in Japan, and 40% of those deaths are attributed to ischemic heart disease...

Background -Innate antigen-presenting cells and adaptive immune T cells have been implicated in the development of hypertension. However, the T-lymphocyte subsets involved in the pathophysiology of hypertension remain unclear. A small subset of "innate-like" T cells expressing the γδ T cell receptor (TCR) rather than the αβ TCR could play a role in the initiation of the immune response in hypertension. We aimed to determine whether angiotensin (Ang) II caused kinetic changes in γδ T cells, whether deficiency in γδ T cells blunted Ang II-induced hypertension, vascular injury and T-cell activation, and whether γδ T cells are associated with human hypertension...
