Filter by:Active parathyroid glands among renal dialysis patients contribute to calcified and hardened blood vessels. Such damage to the blood vessels, in turn, takes a significant toll in terms of cardiovascular disease. Calcimimetics has been suggested to lower the risk of vascular calcification. Role of cinacalcet was demonstrated in animal model but human data are lacking. The investigators designed an open label pilot study to evaluate the effect of cinacalcet in 20 peritoneal dialysis patients with inadequately controlled secondary hyperparathyroidism despite standard treatment. The primary outcome is the aortic pulse wave velocity at 26 and 52 months after cinacalcet treatment.
The present study investigated the long-term (12 months) effect of spironolactone treatment on glucose homeostasis, metabolic parameters and vascular properties.
The overall objectives of this study are to examine the relationships between circulating vitamin D, insulin sensitivity, and multiple indices of vascular function and to examine whether vitamin D deficiency in African Americans (AA) and White Hispanics (WH) is responsible for ethnic differences in insulin sensitivity and hypertension in AA, WH and European Americans (EA), as well as mechanisms underlying the association between insulin resistance and blood pressure. We hypothesize that 1) serum 25(OH)D is associated with insulin sensitivity and vascular functioning, independent of adiposity, 2) lower insulin sensitivity and vascular functioning in AA and WH relative to EA is due to lower circulating 25(OH)D in AA, and 3) the relationship between insulin resistance and vascular dysfunction is mediated by 25(OH)D.

To determine if arterial stiffness as measured by non-invasive pulse wave velocity can predict the response to resynchronization therapy in heart failure.
Recently a new category of antihyperglycemic therapy aiming to modulate the incretin system has emerged. These drugs induce insulin secretion without inducing hypoglycemia. The effect of the incretin modulators drugs on hypertension, arterial stiffness, inflammation and oxidative stress parameters have not been fully investigated yet.GLP-1 analogue has been suggested to have an effect on endothelium and the development of hypertension. Nystrom et al have demonstrated that GLP-1 improves endothelial dysfunction in a small group of type 2 diabetes subjects, with coronary heart disease. We hypothesize that DPP-4 inhibitor will have an effect on hypertension and arterial stiffness by effect on the NO pathway.The aim of this study is to investigate the effect of two insulin inducers drugs, sulfonyl urea and DPP-4 inhibitor on 24 hours blood pressure monitoring, arterial stiffness, oxidative stress and inflammation.
Arterial stiffness refers to the accumulation of extracellular deposits of matrix and calcium which reduce blood vessel compliance. Although there is growing evidence that increased arterial stiffness is associated with chronic kidney disease (CKD), its pathogenesis is unclear. Pulse wave velocity (PWV) and augmentation index (AIx) provide tools for estimating arterial stiffness, and therefore predicting cardiovascular morbidity and mortality. The aims of the study are: (1) compare the effects of nocturnal and conventional haemodialysis on arterial stiffness, and (2) examine the relationship between arterial stiffness and clinical and biochemical parameters.
The purpose of this study is to determine the: - Natural history of calcification posttransplantation - Natural history of BMC following renal transplantation - Reverse correlation between calcification score and aortic calcifications following renal transplantation - Correlation of IMT, BMC, PWV and biochemical variables - Correlation of IMT, BMC, PWV, biochemical variables and outcome - Predictors of CV disease after transplantation - Predictors of IMT progression, BMC loss and PWV progression after renal transplantation
1. Cardiovascular risk is high in patients with renal failure. 2. Cross-sectional studies have indicated a relationship between arterial stiffness and renal function. However, there are no prospective longitudinal studies in the literature. 3. In dialysis patients, arterial stiffness as well as wave reflections, predict mortality. However, there are no data on patients with mild-to-moderate renal impairment available. 4. Therefore, we designed a study to test the hypothesis that: a) measures of arterial stiffness and wave reflections predict the progression of renal impairment in patients with mild-to-moderate renal failure; and b) measures of arterial stiffness and wave reflections predict cardiovascular events in patients with mild-to-moderate renal failure
