Calciprotein particles (CPPs) are a new biological marker of chronic kidney disease-mineral and bone disorder (CKD-MBD). CPPs consist of phosphate, calcium, and some proteins, with phosphate being the major contributor to the level and biological activity of CPPs. Recent studies have shown the physiological and pathological significance of CPPs, including contributions to bone and mineral metabolism, and to tissue and organ impairments such as cardiovascular damage and inflammatory responses. These actions are well known as important aspects of CKD-MBD...

Medial vascular calcification, a major pathophysiological process associated with cardiovascular disease and mortality, involves osteo-/chondrogenic transdifferentiation of vascular smooth muscle cells (VSMCs). In chronic kidney disease (CKD), osteo-/chondrogenic transdifferentiation of VSMCs and, thus, vascular calcification is mainly driven by hyperphosphatemia, resulting from impaired elimination of phosphate by the diseased kidneys. Hyperphosphatemia with subsequent vascular calcification is a hallmark of klotho-hypomorphic mice, which are characterized by rapid development of multiple age-related disorders and early death...

Studies in adult patients suggest that copeptin (C-terminal fragment of antidiuretin propeptide) is related to kidney and cardiovascular diseases. AIM: The aim was to assess copeptin concentration in children with chronic kidney disease (CKD). MATERIALS AND METHODS: In a group of 38 children with CKD (age: from 4.70 to 18.00 mean 12.23±4.19 years) we evaluated: serum copeptin concentration [ng/mL], age, sex, etiology of CKD, presence of arterial hypertension (AH), medications, glomerular filtration rate (GFR), hemoglobin, calcium-phosphorus metabolism parameters, and lipids...

Hard drinking water seems protective against cardiovascular disease compared to soft water. Published data on calcium and magnesium in bottled water products were evaluated to determine water hardness. Data on water chemistry of thirty-three products were obtained from the internet and hardness, as calcium carbonate, was calculated. Approximately two thirds of the products were soft according to criteria of the US Geological Survey; only one fifth were very hard. Beer and wine also were found to be very hard...

Copper is an essential metal for homeostasis and the functioning of living organisms. We investigated the effects of a high copper concentration on the myocardial mechanics, investigating the reactive oxygen species (ROS) mediated effects. The developed force of papillary muscles was reduced after acute exposure to a high copper concentration and was prevented by co-incubation with tempol, DMSO and catalase. The reuptake of calcium by the sarcoplasmic reticulum was reduced by copper and restored by tempol. The contractile response to Ca2+ was reduced and reversed by antioxidants...

Innate immune cells express danger-associated molecular pattern (DAMP) receptors, T-cell co-stimulation/co-inhibition receptors, and the major histocompatibility complex II (MHC-II). We have recently proposed that endothelial cells can serve as innate immune cells, but the molecular mechanisms involved still await discovery. Here, we investigated whether human aortic endothelial cells (HAECs) could be transdifferentiated into innate immune cells by exposing them to hyperlipidemia-upregulated DAMP molecules, i...

BACKGROUND: The calcimimetic agent cinacalcet is effective for the management of secondary hyperparathyroidism (SHPT) in dialysis patients. Changes to reimbursement of cinacalcet in Australia provided an opportunity to assess effects of medication cessation on biochemical and clinical outcomes in dialysis patients, including changes to novel biomarkers such as calciprotein particles (CPP). CPP are nanoparticles of mineral and protein in the circulation associated with increased vascular calcification in patients with chronic kidney disease...

BACKGROUND: Familial hypercholesterolemia (FH) confers an increased risk of premature atherosclerotic disease. Coronary computed tomographic angiography (CTA) can assess preclinical coronary atherosclerosis. OBJECTIVES: To describe coronary CTA findings in asymptomatic molecularly defined FH individuals, to identify those factors related to its presence and extension, and to assess the impact of these results in patients' care and estimated risk. METHODS: Four hundred and forty individuals with FH, without clinical cardiovascular disease, were consecutively enrolled and underwent a coronary CTA that was used to analyze coronary atherosclerosis based on coronary calcium score (CCS), sum of stenosis severity, and plaque composition sum (PCS)...

In chronic kidney disease (CKD), the progressive decrease in renal function leads to disturbances of mineral metabolism that generally cause secondary hyperparathyroidism. The increase in serum parathyroid hormone is associated with reduced serum calcium and calcitriol levels and/or increased serum fibroblast growth factor-23 and phosphate levels. The resulting CKD-associated disorder of mineral and bone metabolism is associated with various other metabolic dysregulations such as acidosis, malnutrition, inflammation, and accumulation of uremic toxins...

Cardiovascular disease is an important complication for patients with chronic kidney disease (CKD), warranting accurate risk prediction, but clinical guidelines are inconsistent regarding whether or how to use information on measures of CKD for predicting risk. Recent large meta-analyses have shown that key CKD measures (estimated glomerular filtration rate and albuminuria) improve cardiovascular risk prediction beyond traditional risk factors, especially when albuminuria is added to prediction models. In addition, several recent studies have shown that the use of filtration markers other than serum creatinine, cystatin C, and β2 -microglobulin can improve cardiovascular risk prediction...

Dilated cardiomyopathy (DCM) can be caused by mutations in the cardiac protein phospholamban (PLN). We used CRISPR/Cas9 to insert the R9C PLN mutation at its endogenous locus into a human induced pluripotent stem cell (hiPSC) line from an individual with no cardiovascular disease. R9C PLN hiPSC-CMs display a blunted β-agonist response and defective calcium handling. In 3D human engineered cardiac tissues (hECTs), a blunted lusitropic response to β-adrenergic stimulation was observed with R9C PLN. hiPSC-CMs harboring the R9C PLN mutation showed activation of a hypertrophic phenotype, as evidenced by expression of hypertrophic markers and increased cell size and capacitance of cardiomyocytes...

PURPOSE: Cardiovascular disease is the leading cause of mortality globally. Epicatechin has previously been shown to improve vascular responses and possess cardioprotective properties. However, the mechanisms underpinning these cardiotropic outcomes remain unknown. The aim of this study was to further identify epicatechin's mechanism of action in the cardiovasculature. METHODS: The effects of epicatechin on isolated rat conduit arteries, resistance vessels and cardiac electrophysiology were investigated on resting tension and precontracted vessels and cardiac action potential parameters, both in the presence and in the absence of various antagonists...

BACKGROUND: Resveratrol is a polyphenolic compound that can be isolated from plants and also is a constituent of red wine. Resveratrol induces relaxation of vascular smooth muscle and may prevent cardiovascular diseases. PURPOSE: Impaired gastric accommodation plays an important role in functional dyspepsia and fundic relaxation and is a therapeutic target of functional dyspepsia. Although drugs for fundic relaxation have been developed, these types of drugs are still rare...

Serum indoxyl sulfate (IS; a uremic toxin) levels, which are significantly higher in patients with chronic kidney disease, including those undergoing hemodialysis, than in the robust, are associated with both cardiovascular disease (CVD) and CVD-related mortality. Furthermore, coronary artery calcium (CAC) is an independent predictor of cardiovascular events in patients undergoing hemodialysis. This study aimed to interpret the association between serum IS levels and coronary plaque burden (CPB) or CAC.A total of 30 consecutive patients on hemodialysis, who underwent 320-row coronary multidetector computed tomography (MDCT) angiography for suspected coronary artery disease, were enrolled in this prospective study...

Endothelin-1 (ET-1) is one of the key factors regulating tension of smooth muscles in blood vessels. It is believed that ET-1 plays an important role in pathogenesis of hypertension, and cardiovascular diseases; therefore, research in order to limit ET-1-mediated action is still in progress. The main objective of this paper was to evaluate the role of Rho-kinase in the ET-1-induced constriction of arteries. The analysis also included significance of intra- and extracellular pool of calcium ions in constriction triggered by ET-1...

BACKGROUND: Hypomagnemia was identified as a strong risk factor for cardiovascular disease in patients with chronic renal failure (CRF). However, the effects of magnesium (Mg) on vascular calcification (VC) have not been fully elucidated. Thus we aim to determine the effects of Mg citrate (MgCit) on VC in CRF rats. METHODS: Rats were divided into 5 groups: group 1 (normal diet); group 2 (normal diet with MgCit); group 3 (VC model of CRF induced by 0.75% adenine and 0...

Patients with CKD have accelerated vascular stiffening contributing significantly to excess cardiovascular morbidity and mortality. Much of the arterial stiffening is thought to involve vascular calcification (VC), but the pathogenesis of this phenomenon is complex, resulting from a disruption of the balance between promoters and inhibitors of calcification in a uremic milieu, along with derangements in calcium and phosphate metabolic pathways. Management of traditional cardiovascular risk factors to reduce VC may be influential but has not been shown to significantly improve mortality...

BACKGROUND: Coronary artery calcification (CAC) is commonly assessed with Agatston score (AS). A higher sensitivity and precision for the detection of CAC has been demonstrated with calibrated mass score (cMS). We hypothesized that cMS would detect low-level CAC not detectable with AS in a large asymptomatic background population. METHODS: Participants (N = 2985) from the Copenhagen General Population Study were evaluated for CAC using both conventional AS and cMS...
