OBJECTIVES: This study analyzed the outcomes of patients who presented with non-ST-elevation myocardial infarction (NSTEMI) and subsequently underwent orbital atherectomy for severe coronary artery calcification (CAC). BACKGROUND: Patients who present with NSTEMI have increased risk for death and recurrent MI after percutaneous coronary intervention (PCI). Patients with severe CAC have worse outcomes after PCI.Orbital atherectomy modifies calcified plaque, facilitating stent delivery and optimizing stent expansion...

PURPOSE: Hemodialysis patients have extremely increased cardiovascular mortality. The coronary artery calcification score (CACS) in uremic patients receiving hemodialysis reflects the severity of atherosclerotic vascular disease and predicts the cardiovascular events. In cardiac conditions, left atrial (LA) size has a prognostic importance. In this study, relationship between coronary artery calcification and left atrial size was investigated. METHODS: This was a cross-sectional study involving 32 hemodialysis patients (16 females, 16 males; mean age, 52...

INTRODUCTION: Epiaortic ultrasound scanning (EAS) extended the use of ultrasound to the intraoperative diagnosis of aortic pathology. Surgical palpation of the ascending aorta underestimates the presence and severity of atherosclerotic plaques. Epiaortic ultrasound scanning has been used as an adjunct to transesophageal echocardiography (TEE) or as a primary direct diagnostic tool for imaging the ascending aorta as well as the aortic arch, which gained prominence as part of a multipronged intraoperative strategy to reduce atherosclerotic emboli...

BACKGROUND: The association between the dialysate calcium level and coronary artery calcification (CAC) has not yet been evaluated in hemodialysis patients. The objective of this study was to determine whether lowering the dialysate calcium levels would decrease the progression of coronary artery calcification (CAC) compared to using standard calcium dialysate. METHODS: We conducted an open-label randomized trial with parallel groups. The patients were randomly assigned to either 12-month treatment with low calcium dialysate (LCD; 1...

Nonalcoholic fatty liver disease may range from simple steatosis to fibrosis and cirrhosis. It is associated with the development of coronary artery calcification and appears to be an independent predictor of future adverse cardiovascular events. As the presence of a fatty liver appears to portray an independent increased risk, it may be beneficial to note this on coronary artery calcium scoring reports. Determination of fatty liver is relatively easy to perform. We discuss the method used by the Multi-Ethnic Study of Atherosclerosis (MESA) study for determination of fatty liver from CT coronary artery calcium scoring acquisitions, which may be implemented in clinical analysis...

BACKGROUND: Cartilage oligomeric matrix protein (COMP) is mainly found in the skeletal system and vascular smooth muscle cells. Recent researches showed that it had a protective function on blood vessels and could also inhibit vascular calcification. We investigated the serum COMPs in coronary heart disease (CHD) patients, and the relationship between serum COMP and the calcification of coronary artery. METHODS: A total of 233 consecutive chest pain patients who first underwent coronary angiography followed by multi-slice computed tomography (MSCT) within six months were recruited and divided into two groups according to the coronary angiography luminal diameter narrowing percentages: CHD group (diameter narrowing ≥ 50%, n = 194) and control group (diameter narrowing < 50%, n = 39)...

Background -Psoriasis, a chronic inflammatory disease associated with an accelerated risk of MI, provides an ideal human model to study inflammatory atherogenesis in vivo We hypothesized that the increased cardiovascular risk observed in psoriasis would be partially attributable to an elevated subclinical coronary artery disease (CAD) burden composed of non-calcified plaques with high-risk features. However, inadequate efforts have been made to directly measure CAD in this vulnerable population. As such, we sought to compare total (TB) and non-calcified (NCB) coronary plaque burden, and high-risk plaque (HRP) prevalence, between psoriasis patients (n=105), hyperlipidemic patients eligible for statin therapy under NCEP-ATP III guidelines (n=100) who were ~10 years older, and non-psoriasis healthy volunteers (HV) (n=25)...

BACKGROUND: Bioprosthetic heart valves (BHVs), fabricated from glutaraldehyde-pretreated bovine pericardium or porcine aortic valves, are widely used for the surgical or interventional treatment of heart valve disease. Reoperation becomes increasingly necessary over time because of BHV dysfunction. METHODS AND RESULTS: Forty-seven explanted BHV aortic valve replacements were retrieved at reoperation for clinically severe BHV dysfunction over the period 2010-2016...

OBJECTIVE: Pulmonary arterial hypertension (PAH) is a vascular disease not restricted to the lungs. Many signaling pathways described in PAH are also of importance in other vascular remodeling diseases, such as coronary artery disease (CAD). Intriguingly, CAD is 4× more prevalent in PAH compared with the global population, suggesting a link between these 2 diseases. Both PAH and CAD are associated with sustained inflammation and smooth muscle cell proliferation/apoptosis imbalance and we demonstrated in PAH that this phenotype is, in part, because of the miR-223/DNA damage/Poly[ADP-ribose] polymerase 1/miR-204 axis activation and subsequent bromodomain-containing protein 4 (BRD4) overexpression...

Vascular calcification is a hallmark of atherosclerosis. The location, density, and confluence of calcification may change portions of the arterial conduit to a noncompliant structure. Calcifications may also seed the cap of a thin cap fibroatheroma, altering tensile forces on the cap and rendering the lesion prone to rupture. Many local and systemic factors participate in this process, including hyperlipidemia, ongoing inflammation, large necrotic cores, and diabetes. Vascular cells can undergo chondrogenic or osteogenic differentiation, causing mineralization of membranous bone and formation of endochondral bone...

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)...

Psoriasis is a multifactorial inflammatory disorder, in which the inflammation affects not only the skin but also the other internal organs, and can induce cardiovascular and cerebrovascular involvements. However, few predictive factors of cardiovascular diseases have been clarified in patients with psoriasis. This study was performed to verify whether diagonal earlobe creases (ELC) can reflect the hidden comorbidities in Japanese psoriatic patients. Prevalence and subtypes of ELC were analyzed in patients with psoriatic and with non-psoriatic skin diseases, and the correlation with coronary artery calcification (CAC) or fatty liver (FL) detected by computed tomography...
