Cardiovascular mortality is markedly increased in chronic kidney disease (CKD) and may be explained in part by sympathetic hyperactivity. Impaired hyperoxic chemoreflex sensitivity (CHRS) has been attributed to an increased sympathetic tone. The aim of the present study was to examine whether chemosensor function is altered in patients with CKD. ...

Cardiovascular disease (CVD) is the leading cause of death among chronic kidney disease (CKD) patients. Vascular calcification is highly prevalent in this population and is an independent predictor of cardiovascular mortality. Vascular calcification in uraemic patients is known to be an active and regulated process subject to the action of ...

Recently, a chronic total occlusion (CTO) in a non-infarct-related artery (non-IRA) and not multivessel disease (MVD) alone was identified as an independent predictor of mortality after ST elevation myocardial infarction (STEMI). Patients with diabetes mellitus (DM) constitute a patient group with a high prevalence of MVD and high mortality after ...

Autoimmunity to heat shock protein 60 (HSP60) has been related to atherosclerosis. Chlamydia pneumoniae (CP), the most studied infectious agent implicated in promoting atherosclerosis, produces a form of HSP60, which can induce an autoimmune response, due to high antigenic homology with human HSP60 (hHSP60). In this study, we evaluated the ...

The soluble receptor of advanced glycation end products (sRAGE) may exert anti-inflammatory protective roles on the vasculature. In contrast, the RAGE ligand S100A12 (also known as EN-RAGE) contributes to inflammation and the development of atherosclerosis in animal models. Whether alterations at this level contribute to the increased mortality observed in ...

Heart failure (HF) is associated with endothelial dysfunction. Endothelium-derived microparticles (EMPs) are a novel quantitative plasma marker of endothelial dysfunction. We investigated whether plasma levels of EMPs can predict future cardiovascular events in patients with HF. We enrolled 169 consecutive HF patients (70 ischaemic, 99 non-ischaemic HF) with New York ...

A high circulating osteoprotegerin (OPG) level may be a risk factor for vascular calcification and mortality in hemodialysis patients. OPG and pulse wave velocity (PWV) were measured at baseline in 151 normoalbuminemic, long-term (>3 years) Japanese hemodialysis patients who were prospectively followed for 6 years. In long-term normoalbuminemic Japanese hemodialysis patients, OPG ...

BACKGROUND: Several reports have found that chronic kidney disease (CKD) is an independent risk factor for stroke. However, little is known about whether cerebrovascular disease conversely predicts the outcome of kidney function. In view of the similarities between vascular beds of the kidney and brain, we hypothesized that silent brain ...

Endothelium-dependent flow-mediated dilation (FMD) is measured as the increase in diameter of a conduit artery in response to reactive hyperemia, assessed either at a fixed time point [usually 60-s post-cuff deflation (FMD(60))] or as the maximal dilation during a 5-min continuous, ECG-gated, measurement (FMD(max-cont)). Preliminary evidence suggests that the time ...
