Coronary artery calcification is a part of atherosclerosis process associated with coronary heart disease. Recently, coronary artery calcification assessment using computed tomography (CT) is still the best noninvasive imaging with high sensitivity and specificity. Osteoprotegerin (OPG) is one of vascular calcification marker that through its role to bind receptor activator of nuclear factor-κβ ligand and inhibit osteoclastogenesis is suspected of playing a role for coronary calcification in atherosclerosis process...

Background -Computed tomography (CT) allows estimation of coronary artery calcium (CAC) progression. We evaluated several progression algorithms in our unselected, population-based cohort for risk prediction of coronary and cardiovascular (CV) events. Methods -In 3281 participants (45-74 years), free from CV disease until the 2(nd) visit, risk factors and CTs at baseline (b) and after a mean of 5.1 years (5y) were measured. Hard coronary and cardiovascular events as well as total CV events including revascularization were recorded during a follow-up time of 7...

REVIEW
Andrea Schampel, Stefanie Kuerten
Voltage-gated calcium channels (VGCCs) are widely distributed within the central nervous system (CNS) and presumed to play an important role in the pathophysiology of a broad spectrum of CNS disorders including Alzheimer's and Parkinson's disease as well as multiple sclerosis. Several calcium channel blockers have been in clinical practice for many years so that their toxicity and side effects are well studied. However, these drugs are primarily used for the treatment of cardiovascular diseases and most if not all effects on brain functions are secondary to peripheral effects on blood pressure and circulation...

Airflow obstruction is associated with increased cardiovascular morbidity and mortality. However, the causal mechanisms linking airflow obstruction with higher incidence of cardiovascular events remain elusive. We evaluated the relationship between airflow obstruction, a key feature of chronic obstructive pulmonary disease (COPD), and prevalence, extent, and severity of coronary atherosclerosis in a large cohort of asymptomatic subjects. Participants were recruited from those undergoing spirometry and coronary computed tomography angiography (CCTA) as part of a general health evaluation from March 2009 to February 2011...

Vascular calcification is a pathology characterized by the deposition of calcium-phosphate in cardiovascular structures, mainly in the form of hydroxyapatite crystals, resulting in ectopic calcification. It is correlated with increased risk of cardiovascular disease and myocardial infarction in diabetic patients and in those with chronic kidney disease (CKD). Vascular smooth muscle cells are sensitive to changes in inorganic phosphate (Pi) levels. They are able to adapt and modify some of their functions and promote changes which trigger calcification...

The association between ionising radiation (IR) exposure and risk of cardiovascular diseases (CVD) is well documented, but the underlying mechanism is still poorly understood. As atherosclerotic plaques are the most common cause of CVD, we investigated the effects of IR on one of the critical parameters for atherosclerotic plaque formation - endothelium permeability to macromolecules. We used endothelial cells from human coronary artery as a model of the endothelial layer. Our results show that exposure of this endothelial layer to IR increased its permeability to macromolecules of various sizes in a dose-dependent manner...

Vitamin D plays an important role in maintaining calcium and bone metabolism, a risk factor of osteoporosis, fall and fracture in old age. Reduction in D-vitamin levels associated with compensatory increased level of parathyroid hormone causes significant loss of bone matrix, so substitutions of vitamin D and calcium are very important. Many authors publish their recommended doses used for prevention of hip fracture during the last years. Some authors are satisfied only with vitamin D supplementation while others have better experiences with vitamin D and calcium substitution...

INTRODUCTION: Vascular calcification (VC) in hemodialysis (HD) patients is a sign of severe cardiovascular disease and can predict cardiovascular outcomes. Fetuin-A and osteopontin (OPN) inhibit VC. Serum fetuin-A levels are lower in patients with end-stage kidney disease (ESKD) and in those who are on chronic HD therapy. However, there are limited data concerning OPN in patients who are on dialysis. The aim of our study was to determine VC in HD patients, the relationship between VC and 25-OH-vitamin D, fetuin-A, and OPN levels, and independent predictors of VC...

Background: Epidemiologic and clinical data have suggested the existence of a biologic linkage between the bone system and the vascular system. Bisphosphonates (BPs) are effective inhibitors of bone resorption and are currently considered the drugs of choice for the prevention and treatment of osteoporosis and related fractures. Data from several publications have suggested that BPs may also be effective in reducing the atherosclerotic process and vascular calcification, but the results of these studies are contrasting...

Hyperproliferation of vascular smooth muscle cells (VSMC) is a major risk factor for cardiovascular diseases. Proper mitochondrial fission and fusion is involved with VSMC function. However, the role and mechanism of mitochondrial morphological changes in VSMC proliferation are not well understood. Here, we found that calcium sensing receptor (CaSR) was increased in the aortas from spontaneous hypertensive rats (SHRs) compared with age-matched Wistar Kyoto (WKY) rats. There was also an increase in mitochondrial fission and VSMC proliferation, which was attenuated by Calhex231...

Associations of calcium and dairy product intakes with cardiovascular disease risk and cancer mortality are controversial. We investigated associations of calcium and dairy product intakes with mortality in the prospective REasons for Geographic and Racial Differences in Stroke study (n = 30,239). Of 2,966 total deaths, 32.3% were from CVD and 28.8% from cancer. For those in the upper relative to the lowest quintile of intakes, from Cox proportional hazards regression models, the multivariable-adjusted hazard ratios (HRs) for all-cause mortality were 1...

C-reactive protein (CRP), a biomarker for cardiovascular disease, has been reported to have a strong affinity to zwitterionic phosphorylcholine (PC) groups in the presence of calcium ions. In addition, PC-immobilized surfaces have been used as a nonfouling coating to prevent nonspecific protein binding. By appropriately use the features of PC-immobilized surfaces, including specific recognition to CRP and non-fouling surface, it is reasonable to create an antibody-free biosensor for the specific capture of CRP...

Aims: Compared to the general population, mortality is significantly increased in renal transplant recipients. In the general population, coronary artery calcification (CAC) and its evolution over time are associated with cardiovascular and all-cause mortality, and the study of this biomarker could provide useful information for describing the long-term progression of coronary heart disease in renal transplant recipients. Methods: We followed up a cohort of 113 renal transplant patients by performing three multi-detector computed tomography studies over 83...

Importance: Current guidelines for atherosclerotic cardiovascular disease focus on high-intensity statins and targeting or using a threshold low-density lipoprotein cholesterol (LDL-C) level of less than 70 mg/dL for the highest-risk patients. Whether further reduction of LDL-C beyond these boundaries would be beneficial is unknown. Objective: To compare outcomes of evolocumab vs placebo in patients with stable atherosclerotic cardiovascular disease and a baseline LDL-C of less than 70 mg/dL and in those receiving background treatment with a maximal-potency statin...

Importance: Although the risk of type 2 diabetes is considered to be equivalent to coronary heart disease (CHD) risk, there is considerable heterogeneity among individuals for CHD and atherosclerotic cardiovascular disease (ASCVD) risk. It is not known whether coronary artery calcium (CAC) assessment at baseline in individuals with established metabolic syndrome (MetS) or diabetes identifies CHD and ASCVD prognostic indicators during a long follow-up period. Objective: To compare improvement in long-term prognostication of incident CHD and ASCVD using CAC scores among those with diabetes, MetS, or neither condition...

Andrographolide (ANDRO) is a diterpene lactone compound with extensive biological effects, such as antibacterial, antitumor and treatment of cardiovascular diseases. Until now, studies on the pharmacological functions of ANDRO are still in progress. However, little is known about the gene expression profile and calcium response of endothelial cells to ANDRO. In this study, we used a microarray technology to investigate the gene expression responses in primary rat myocardium microvascular endothelial cells (RMMECs) treated with 10μg/mL ANDRO...

Clinical guidelines for instituting pharmacotherapy for the primary prevention of atherosclerotic cardiovascular disease (ASCVD), specifically lipid management and aspirin, have long been based on absolute risk. However, lipid management in the current era remains challenging to both patients and clinicians in the setting of somewhat discordant recommendations from various organizations. All guidelines endorse the use of statins for primary prevention for those at sufficient absolute risk, and treatment recommendations are generally "risk-based" rather than exclusively targeting specific low-density lipoprotein cholesterol levels...

A high prevalence of mitral annular calcium (MAC) is expected in patients undergoing transcatheter aortic valve implantation (TAVI); however, data regarding the prevalence of MAC and impact on risk of cardiovascular events are lacking. To determine the prevalence of MAC and its association with clinical outcomes in patients undergoing TAVI, we retrospectively analyzed 424 patients who underwent transfemoral TAVI from 2007 to 2015 and whose preoperative computed tomography images were available for assessment of MAC...

Endothelial cell insulin resistance may be partially responsible for the higher risk of atherosclerosis and cardiovascular disease in populations with insulin resistance and type 2 diabetes mellitus (T2DM). A genome-wide association study revealed a significant association between the ATPase plasma membrane Ca(2+) transporting 1 (ATP2B1) gene and T2DM in two community-based cohorts from the Korea Association Resource Project. However, little is known about the implication of the ATP2B1 gene on T2DM. In the present study, we investigated the role of the ATP2B1 gene in endothelial cell insulin sensitivity...

Angiotensin 1-converting enzyme (ACE) levels in man are under strong genetic influence. Genetic variation in ACE has been linked to risk for, and progression of, cardiovascular and renal diseases. Causality has been documented in genetically modified mice but mechanisms underlying causality are not completely elucidated. To further document the vascular and renal consequences of a moderate genetic increase in ACE synthesis, we studied genetically modified mice carrying three copies of the ACE gene (3-copy mice) and littermate wild type animals (2-copy mice)...
