Osteopontin (OPN) is a phosphorylated glycoprotein secreted into body fluids by various cell types. OPN contains arginine-glycine-aspartate (RGD) and serine-leucine-alanine-tyrosine (SLAY) motifs that bind to several integrins and mediate a wide range of cellular processes. In the present study, the proangiogenic effects of a 20-amino-acid OPN peptide (OPNpt20) containing RGD and SLAY motifs were examined in human umbilical vein endothelial cells (HUVECs) and in a rat focal cerebral ischemia model. OPNpt20 exerted robust proangiogenic effects in HUVECs by promoting proliferation, migration and tube formation...

We present a case of a 70-year-old man who was admitted with rupture of an abdominal aneurysm 4 years after endovascular aneurysm repair. He was compliant with yearly follow-up computed tomography angiography. One month earlier, his computed tomography angiogram showed perfect exclusion of the aneurysm and no endoleak. We explanted the stent graft and confirmed effective sealing, and the graft was intact. We found no signs of infection during 2 years of follow-up. This rupture is nonpredictable and unexplained and illustrates that unremarkable imaging does not guarantee prevention of rupture...

AIMS: Variability in response to Renin-Angiotensin-Aldosterone System (RAAS) inhibition has been shown in clinical trials but its occurrence and impact in clinical practice are unknown. We assessed variability in systolic blood pressure (SBP) and albuminuria (UACR) responses in patients with type 2 diabetes mellitus initiating RAAS inhibition, and assessed the association of response variability with cardiovascular outcomes. METHODS: We performed an observational cohort study in patients with type 2 diabetes who started RAAS inhibition between 2007 and 2013 (n=1600) were identified from general practices in the Netherlands...

Vascular procedures in general, and specifically abdominal aortic aneurysm (AAA) repair, are associated with worse outcomes in female patients. However, how female gender influences outcomes in the setting of aneurysm-rupture remains unclear and may be even more pronounced when compared to elective operations. In this report, the authors aim to review the literature regarding ruptured AAA repair in women. Using the traditional threshold for AAA of 30mm of maximum diameter, the prevalence in women is lesser than in men...

BACKGROUND: In type 1 diabetes (T1D), adjuvant treatment with inhibitors of the renin-angiotensin-aldosterone system (RAAS), which dilate the efferent arteriole, is associated with prevention of progressive albuminuria and renal dysfunction. Uncertainty still exists as to why some individuals with long-standing T1D develop diabetic kidney disease (DKD) while others do not (DKD resistors). We hypothesized that those with DKD would be distinguished from DKD resistors by the presence of RAAS activation...

Chronic thromboembolic pulmonary hypertension (CTEPH) has a poor prognosis because of the associated progressive right heart failure. Accurate evaluation of right ventricular (RV) function would thus be useful to predict prognosis. However, the significance of RV diastolic function remains unclear. We aimed to identify which echocardiographic measures are most accurate, and potentially useful, in assessing RV diastolic function in patients with CTEPH, and to study the effects of balloon pulmonary angioplasty (BPA) on them...

Previous studies have demonstrated that connexin40 (Cx40) remolding is involved in atrial fibrillation (AF). GJA5 encoding Cx40 is a potential target mRNA of microRNA-208a-3p (miR-208a-3p), as indicated by preliminary bioinformatics analyses. However, the exact effect of miR-208a-3p on Cx40 in human chronic AF has remained elusive. The present study demonstrated the role of miR-208a-3p in human chronic AF and further investigated the effect of miR-208a-3p on Cx40 expression. A total of 19 patients with AF and 18 patients with sinus rhythm (SR) were enrolled...

The renin angiotensin aldosterone system (RAAS) plays a central role in the pathophysiology of hypertension and vascular disease. Angiotensin-converting enzyme inhibitors (ACEi's) suppress angiotensin II (ANG II) concentrations, whereas angiotensin II type 1 (AT1) receptor blockers (ARBs) block the binding of ANG II to AT1 receptors. ACEi's and ARBs are both effective antihypertensive agents and produce similar risk reductions for stroke, a blood pressure-dependent phenomenon. ACEi's also reduce the risk for myocardial infarction (MI) and all-cause mortality in high-risk hypertensive patients as well as in people with diabetes, vascular disease and congestive heart failure...

Among patients with proteinuric chronic kidney disease (CKD), current guideline recommendations mandate the use of agents blocking the renin angiotensin aldosterone system (RAAS) as first-line antihypertensive therapy based on randomized trials demonstrating that RAAS inhibitors are superior to other antihypertensive drug classes in slowing nephropathy progression to end-stage renal disease. However, the opportunities for adequate RAAS blockade in CKD are often limited, and an important impediment is the risk of hyperkalemia, especially when RAAS inhibitors are used in maximal doses or are combined...

Cardiovascular diseases are the leading cause of death. The underlying pathophysiology is largely contributed by an overactivation of the renin-angiotensin-aldosterone-system (RAAS). Herein, angiotensin II (AngII) is a key mediator not only in blood pressure control and vascular tone regulation, but also involved in inflammation, endothelial dysfunction, atherosclerosis, hypertension and congestive heart failure. Since more than three decades suppression of AngII generation by inhibition of the angiotensin-converting enzyme (ACE) or blockade of the AngII-receptor has shown clinical benefit by reducing hypertension, atherosclerosis and other inflammation-associated cardiovascular diseases...
