OBJECTIVE: Vitamin K antagonists (VKA) are associated with increased vascular calcification which may lead to an elevated cardiovascular risk. If the direct anticoagulants (DOACs) have similar negative vascular effects is unknown. We evaluated the influence of different anticoagulation strategies on coronary artery disease (CAD) using coronary computed tomography angiography (CTA). METHODS: Overall 702 consecutive patients with non-valvular atrial fibrillation (AF) who underwent CTA for AF ablation planning were enrolled and stratified according to their anticoagulation into VKA, DOAC (all agents) and a control group without oral anticoagulation...

BACKGROUND: Recent studies demonstrated that calcification of arteries supplying the gastric tube is associated with anastomotic leakage after esophagectomy. However, it remains unclear whether this association only derives from local flow limitations, or generalized vascular disease as well. The purpose of this study was to determine whether calcification throughout the entire cardiovascular system is associated with anastomotic leakage. METHODS: Consecutive patients who underwent an esophagectomy with gastric tube reconstruction and cervical anastomosis for esophageal cancer were analyzed...

A 62-year-old Japanese man presented with chest pain indicating that acute myocardial infarction had occurred. Eleven years earlier, he underwent a splenectomy due to idiopathic portal hypertension. Coronary angiography revealed diffuse stenosis, with calcification in the left anterior descending coronary artery (LAD). We performed a primary percutaneous coronary intervention (PCI). We deployed two drug-eluting stents with sufficient minimal cross-sectional stent area by intravascular ultrasound and thrombolysis in myocardial infarction (TIMI) 3 flow...

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...

GOALS: Because of shared risk factors between clinically manifest cardiovascular disease and colorectal cancer, we hypothesized the coexistence of subclinical atherosclerosis measured by coronary artery calcium (CAC) and colorectal adenoma (CRA) and that these 2 processes would also share common risk factors. BACKGROUND: No study has directly compared the risk factors associated with subclinical coronary atherosclerosis and CRA. STUDY: This was a cross-sectional study using multinomial logistic regression analysis of 4859 adults who participated in a health screening examination (2010 to 2011; analysis 2014 to 2015)...

BACKGROUND: Aorto-ostial lesions as well as bifurcation lesions still provide challenges in percutaneous coronary intervention (PCI), as meticulous stent placement is needed. The Szabo-technique, which uses a second wire to anchor the stent at the osmium, may be helpful here. In this article, we will provide detailed information on the technique including video material as well as procedural and long-term follow-up data of a cohort of patients treated with this technique. METHODS AND RESULTS: A retrospective single-centre study was performed in patients undergoing Szabo-PCI from 2014 to 2016 (n=28)...

Gender differences exist in clinical outcomes after routine percutaneous coronary intervention (PCI), but studies reporting such outcomes after chronic total occlusion (CTO) PCI are limited. We assessed the characteristics and outcomes of female patients undergoing CTO PCI. We retrospectively analyzed a dedicated national (United Kingdom) prospective CTO database from 2011 to 2015 for outcomes and characteristics of female patients undergoing CTO PCI (unmatched and propensity matched). Female patients constituted 20...

Chronic kidney disease (CKD) mineral and bone disorders (CKD-MBD) may lead to low bone mineral density (BMD) and vascular calcification (VC), but links to the latter are unclear. Here we investigated associations between BMD, coronary artery calcium (CAC) scores, and histological signs of VC in end-stage renal disease (ESRD) patients undergoing living-donor kidney transplantation (LD-Rtx). In 66 ESRD patients (median age 45 years, 68% males), BMD (by dual-energy X-ray absorptiometry, DXA), CAC score (by computed tomography, CT; n = 54), and degree of VC score (graded by histological examination of epigastric artery specimens collected at LD-Rtx; n = 55) were assessed at the time of LD-Rtx...

Coronary artery calcification (CAC) is a known risk factor for adverse outcomes in the general population and in patients with coronary artery disease. We performed a survey of United States radiologists to evaluate the trends in reporting the presence or absence of CAC on NCCT examinations. An 11 multiple-choice questionnaire was distributed to members of the American College of Radiology, and 530 members participated in the study. Eighty-seven percent of the analyzed group report the presence of CAC on standard CT scans of the chest, and approximately half them (52 %) use a qualitative modifier...

BACKGROUND/OBJECTIVES: Carotid intimal media thickness (IMT) and coronary calcium scores (CCS) are thought to reflect atherosclerotic burden. The validity of this assumption for IMT is challenged by recent meta-analyses; for CCS by absence of a relationship between negative scores, and freedom of future events. As such, we considered evaluation of the relationship between tissue IMT and CCS, and extend of atherosclerotic disease relevant. METHODS: Analyses were performed on donor aortas obtained during renal graft procurement, and on coronary arteries collected during heart valve procurement for tissue donation...

BACKGROUND: Coronary artery calcification (CAC) is an independent predictor of cardiovascular morbidity and mortality in chronic kidney disease (CKD) patients. The aim of the present study was to evaluate the predictive value of CAC scores for the incidence of contrast-induced nephropathy (CIN) after cardiac catheterization in non-dialyzed CKD patients. METHODS: The present study evaluated a total of 140 CKD patients who underwent cardiac catheterization. Patients were stratified into two groups based on the optimal cut-off value of the CAC score, which was graded by a non-triggered, routine diagnostic chest computed tomography scan: CAC score ≥8 (high CAC group); and CAC score <8 (low CAC group)...
