We investigated the influence of genetic variants on atherosclerosis using whole exome sequencing in cases and controls from the autopsy study "Pathobiological Determinants of Atherosclerosis in Youth (PDAY)". We identified a PDAY case group with the highest total amounts of raised lesions (n = 359) for comparisons with a control group with no detectable raised lesions (n = 626). In addition to the standard exome capture, we included genome-wide proximal promoter regions that contain sequences that regulate gene expression...

BACKGROUND: Enlargement of the proximal aorta is associated with aortic wall tissue remodeling, including fragmentation of the elastin fibers, increased synthesis of collagen, and calcification, all of which are associated with aortic wall stiffening. We hypothesized that the proximal aortic diameter (AoD) is associated with cardiovascular events in a community-based cohort of blacks. METHODS AND RESULTS: We investigated the associations between AoD and cardiovascular events among 3018 black participants (mean age, 55...

BACKGROUND AND AIMS: Despite statin treatment, a high prevalence of severe vascular calcification is found in patients with familial hypercholesterolemia (FH). We assessed the relation between the circulating soluble form of low-density lipoprotein receptor relative with 11 ligand-binding repeats (sLR11), a risk factor for cardiovascular disease, and vascular calcification in asymptomatic statin-treated heterozygous FH patients. METHODS: In 123 asymptomatic heterozygous FH patients (age 40-69 years), aortic root (ARC), aortic valve (AVC) and coronary artery calcification (CAC) were determined with CT-based calcium scoring expressed in Agatston units...

Background Clonal hematopoiesis of indeterminate potential (CHIP), which is defined as the presence of an expanded somatic blood-cell clone in persons without other hematologic abnormalities, is common among older persons and is associated with an increased risk of hematologic cancer. We previously found preliminary evidence for an association between CHIP and atherosclerotic cardiovascular disease, but the nature of this association was unclear. Methods We used whole-exome sequencing to detect the presence of CHIP in peripheral-blood cells and associated such presence with coronary heart disease using samples from four case-control studies that together enrolled 4726 participants with coronary heart disease and 3529 controls...

BACKGROUND: Coronary artery calcification (CAC) is a predictor of cardiovascular events and plaque burden and is closely associated with chronic inflammation. Interleukin (IL)-37 is a newly discovered member of the IL-1 family and is considered an anti-inflammatory cytokine. Our recent study on mice indicated that IL-37 could attenuate atherosclerosis and vascular calcification, which suggests that IL-37 could be associated with the development of atherosclerosis and related diseases...

OBJECTIVES: This study sought to determine whether coronary artery calcium (CAC) could be used to optimize statin allocation among individuals for whom trial-based evidence supports efficacy of statin therapy. BACKGROUND: Recently, allocation of statins was proposed for primary prevention of atherosclerotic cardiovascular disease (ASCVD) based on proven efficacy from randomized controlled trials (RCTs) of statin therapy, a so-called trial-based approach. METHODS: The study used data from MESA (Multi-Ethnic Study of Atherosclerosis) with 5,600 men and women, 45 to 84 years of age, and free of clinical ASCVD, lipid-lowering therapy, or missing information for risk factors at baseline examination...

Arterial calcification is a major complication of cardiovascular disease. Oestrogen replacement therapy in postmenopausal women is associated with lower levels of coronary artery calcification, but its mechanism of action remains unclear. Here, we show that oestrogen inhibits the osteoblastic differentiation of vascular smooth muscle cells (VSMCs) in vitro and arterial calcification in vivo by promoting autophagy. Through electron microscopy, GFP-LC3 redistribution, and immunofluorescence analyses as well as measurement of the expression of the autophagosome marker light-chain I/II (LC3I/II) and autophagy protein 5 (Atg5), we show that autophagy is increased in VSMCs by oestrogen in vitro and in vivo...

We present cardiac computed tomography (CT) findings demonstrating apical hypertrophic cardiomyopathy with dystrophic calcification of the left ventricular apex. The absence of significant epicardial coronary artery disease demonstrated by coronary CT angiography suggests that increased wall tension and decreased microvascular perfusion over time account for the dyskinetic apical myocardium, rather than myocardial infarction secondary to atherosclerotic plaque rupture. These observations support CT as the imaging modality of choice to visualize the deposition of calcium in injured myocardial tissue, a recognized occurrence in chronically infarcted myocardium...

Objective We aimed to determine the capacity of drug-eluting stent (DES) over-expansion in left main coronary artery disease. Methods Left main interventions with the largest available DES platforms (4.0 mm) and post-dilation performed with large non-compliant balloons (≥ 4.5 mm) were included. Maximal stent diameter (mm) and area (mm(2)) were measured using post-intervention intravascular ultrasound (IVUS). Stent diameter and area were calculated with the balloon diameter and inflation pressure. The diameter and area expansion indices were defined as follows: maximal/calculated stent diameter and maximal/calculated stent area, respectively...

OBJECTIVE: Vascular calcifications are associated with nephrolithiasis. While studies have demonstrated correlations with vascular disease and calcium stones in kidney stone formers (KSF), an etiologic link has remained elusive. As a non-contrast CT scan (NCCT) is typically part of a stone evaluation, our objective was to evaluate the association of NCCT-based assessment of abdominal aortic calcifications (AAC) with 24-hour urine parameters and stone composition. MATERIALS AND METHODS: 97 KSF were included with CT imaging and 24-hour urine studies...

BACKGROUND: Vascular calcification has been found to be associated with increased risk of cardiovascular (CV) morbidity and mortality. Various bone-associated proteins have been suggested to be related with this process. In this study, we aimed to evaluate whether serum levels of bone morphogenic protein-4 (BMP-4) and matrix Gla protein (MGP) differed in patients who were found to have normal epicardial coronary arteries or a culprit lesion in the coronary angiography leading to acute coronary syndrome (ACS)...

Frailty is a risk factor for cardiovascular diseases (CVD), but the studies available have not considered the presence of sub-clinical atherosclerotic disease as potential confounders. We investigated the association between frailty and the onset of CVD independently of sub-clinical atherosclerotic disease. For this reason, a sample of 3818 older participants participating in the Age, Gene/Environment SusceptibilityReykjavik Study (AGESReykjavik) without CVD at baseline was followed for a median of 8...

M Meyer, T Henzler
The quantification of coronary calcifications using noncontrast-enhanced computed tomography (CT) as well as coronary CT angiography (cCTA) have rapidly evolved in the recent years. Nowadays, both techniques are increasingly clinically accepted regarding risk stratification and accurate exclusion of significant coronary artery disease (CAD). The higher acceptance of cCTA is mainly based on the higher robustness, lower radiation exposure through continuous technical innovations as well as by the growing scientific evidence...
