OBJECTIVES: We assessed the safety and efficacy of orbital atherectomy to modify severely calcified coronary plaque prior to stent implantation in patients with small vessel (2.5mm) disease. BACKGROUND: Severe coronary artery calcification increases the risk of adverse clinical events during percutaneous coronary intervention (PCI). Patients who undergo PCI of small vessels have worse clinical outcomes including higher rates of perforation and dissection. The outcomes of orbital atherectomy of small diameter vessels (2...

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...

OBJECTIVES: To assess pre-procedural plaque characteristics as determined by coronary CT angiography (CCTA) and their associations with late revascularization in symptomatic post-procedural patients. METHODS: Symptomatic patients with pre-procedural CCTA were prospectively enrolled and referred for invasive coronary angiography (ICA). Plaque characterization was performed on the basis of baseline CCTA data. Multivariate logistic regression analysis with a stepwise selection method was performed to identify independent predictors of late revascularization...

Differences in thyroid function status within the euthyroid range have been proposed to affect the development of (subclinical) atherosclerosis [1], as evidenced by a greater carotid artery intima media thickness and progression of coronary artery calcification in the context of low normal thyroid function, i.e. a higher thyroid stimulating hormone (TSH) or a lower free thyroxine (FT4) thyroid hormone in the euthyroid range [2,3]. Importantly, with respect to high density lipoproteins (HDL) the concept is emerging that abnormalities in function rather than low concentrations of HDL cholesterol per se may give rise to impaired atheroprotective potential of this lipoprotein fraction...

INTRODUCTION: Coronary artery disease (CAD) not amenable to revascularisation indicates that the coronary arteries have severe diffuse lesions or calcifications, or that CAD is complicated with severe multiple-organ disease. Currently, Western medicines available for the treatment of CAD not amenable to revascularisation are limited. Shexiang Baoxin Pill (SBP), a type of Chinese patent medicine, has been widely used to treat CAD in China for many years. Previous studies have shown that long-term administration of SBP (1-2 pills three times daily, for at least 6 months) for treatment of CAD is effective and safe, with a significant, long-term effect...

BACKGROUND: Incidence and prevalence of cardiovascular disease (CVD) differ between sexes, and women experience CVD later than men. Changes in fibrin clot lysability are associated with CVD, and the present study addresses sex differences in fibrin clot lysability in asymptomatic middle-aged individuals and the relation to coronary artery calcification (CAC). METHODS: Participants free of morbidities and medication, N = 163, were randomly chosen from a national registry among citizens, 50 or 60 years of age, and were followed for 5 years...

Several studies revealed that traditional risk factors are less effective in predicting CVD risk in the elderly, suggesting the need to identify new biomarkers. Here we evaluated the association between serum cholesterol efflux capacity (CEC), an atheroprotective property of HDL recently identified as a novel marker of CVD risk, and atherosclerotic burden in a cohort of very old, healthy individuals. Serum CEC values were not significantly correlated neither with calcium score nor with markers of vulnerable plaque, such as positive remodeling, hypodensity, spotty calcification or napking-ring sign...

AIMS: Drug-coated balloons (DCBs) are a recognized alternative to stents for the treatment of in-stent restenosis (ISR), and there is some initial clinical evidence about their efficacy for the treatment of small coronary vessels. Newer-generation DCBs were developed to overcome the reduced deliverability of the previous generation, also warranting a more effective drug delivery to vessel wall. However, the vast majority of new-generation DCBs still lack of reliability due to paucity of clinical data...

Heavy smokers undergoing screening with low-dose chest CT are affected by cardiovascular disease as much as by lung cancer. Low-dose chest CT scans acquired in screening enable quantification of atherosclerotic calcifications and thus enable identification of subjects at increased cardiovascular risk. This paper presents a method for automatic detection of coronary artery, thoracic aorta, and cardiac valve calcifications in low-dose chest CT using two consecutive convolutional neural networks. The first network identifies and labels potential calcifications according to their anatomical location and the second network identifies true calcifications among the detected candidates...

BACKGROUND AND AIMS: Inflammatory biomarkers and adipocytokines (IBA) may contribute to atherosclerosis by promoting vascular inflammation. The association between IBA and coronary artery calcium (CAC), a marker of subclinical atherosclerosis, is not well defined in South Asians (SA). We hypothesized that IBA (high sensitivity C-reactive protein [hsCRP], tumor necrosis factor alpha [TNF-α], adiponectin, and leptin) were independently associated with and improved discrimination of CAC among SA...

BACKGROUND: Abdominal aortic calcification (AAC) score in dialysis patients was associated with coronary artery disease (CAD) in cross-sectional study, but the use of AAC score in the CAD occurrence prediction was not clear. We aimed to use AAC score in the estimation of CAD occurrence in middle-aged peritoneal dialysis (PD) patients. METHODS: Middle-aged (45-65 years old) PD patients were recruited and followed up until CAD occurrence, patient mortality, or PD failure...

OBJECTIVES: To investigate diagnostic accuracy and radiation dose of high-pitch CT coronary artery calcium scoring (CACS) with tin filtration (Sn100kVp) versus standard 120kVp high-pitch acquisition. METHODS: 78 patients (58% male, 61.5±9.1 years) were prospectively enrolled. Subjects underwent clinical 120kVp high-pitch CACS using third-generation dual-source CT followed by additional high-pitch Sn100kVp acquisition. Agatston scores, calcium volume scores, Agatston score categories, percentile-based risk categorization and radiation metrics were compared...

BACKGROUND AND AIMS: Studies have shown that soluble urokinase Plasminogen Activator Receptor (suPAR) and CRP (both inflammatory markers) and coronary artery calcification (CAC) are independent risk predictors for cardiovascular (CV) disease. The aim of this study is to assess whether suPAR and CRP have an increased predictive prognostic value beyond the traditional CV risk factors and the CAC score. METHODS: A population sample of 1179 subjects, free of CV disease was included...

We have developed a technique to image coronary calcium, an excellent biomarker for atherosclerotic disease, using low cost, low radiation dual energy (DE) chest radiography, with potential for widespread screening from an already ordered exam. Our dual energy coronary calcium (DECC) processing method included automatic heart silhouette segmentation, sliding organ registration and scatter removal to create a bone-image-like, coronary calcium image with significant reduction in motion artifacts and improved calcium conspicuity compared to standard, clinically available DE processing...

Recent epidemiological studies have revealed that the risk factors associated with coronary artery calcification (CAC), including male gender, smoking, hypertension, and elevated serum cholesterol, are similar to the risk factors associated with the development of calcific aortic valve disease (CAVD). The results of the experimental and clinical studies demonstrate that traditional risk factors initiate early atherosclerosis which over time differentiates to form bone in the heart causing clinical CAC and CAVD...

Cardiovascular disease (CVD) is a common cause of death in patients with chronic kidney disease (CKD). Aortic and mitral valve calcification (AVC and MVC, respectively) are critical indicators of CVD and all-cause mortality in CKD patients.We conducted a single center retrospective study of Chinese inpatients with CKD to identify risk factors associated with valve calcification (VC).Of 288 enrolled CKD patients, 22.9% had VC, all of which exhibited AVC, while 21.2% exhibited MVC. The VC group were significantly older than the non-VC group (70...

REVIEW
Daniel Bos, Maarten J G Leening
Non-contrast cardiac computed tomography in order to obtain the coronary artery calcium score has become an established diagnostic procedure in the clinical setting, and is commonly employed in clinical and population-based research. This state-of-the-art review paper highlights the potential gain in information that can be obtained from the non-contrast coronary calcium scans without any necessary modifications to the scan protocol. This includes markers of cardio-metabolic health, such as the amount of epicardial fat and liver fat, but also markers of general health including bone density and lung density...

OBJECTIVES: We assessed the impact of intravascular ultrasound (IVUS)/optical coherence tomography (OCT) on outcomes of patients who underwent orbital atherectomy. BACKGROUND: Intravascular imaging provides enhanced lesion morphology assessment and optimization of percutaneous coronary intervention (PCI) outcomes. Severe coronary artery calcification increases the complexity of PCI and is associated with worse clinical outcomes. Orbital atherectomy modifies calcified plaque, facilitating stent delivery and optimizing stent expansion...
