BACKGROUND AND AIMS: Disruption of atherosclerotic plaque and distal embolism often cause peri-procedural myocardial injury during percutaneous coronary intervention (PCI). In the present study, we evaluate the association between the characteristics of the target lesion and the amount of debris captured by the filter-type distal protection device. METHODS: We enrolled 120 consecutive patients with acute coronary syndrome, who underwent coronary stent implantation with a filter-type distal protection device after integrated backscatter intravascular ultrasound (IB-IVUS) analysis...

BACKGROUND: Thin-cap fibroatheroma (TCFA) is assumed to cause acute coronary syndromes. OBJECTIVE: To compare the accuracy of different models for diagnosing TCFA using parameters derived by CT, validated against optical coherence tomography (OCT). METHODS: One hundred twenty-nine plaques in 106 patients were analyzed using data acquired by 64-row CT with a reconstruction thickness of 0.67 mm and an increment of 0.33 mm. TCFA was defined by OCT as a plaque with lipid content in ≥2 quadrants and the thinnest part of the fibrous cap measuring ≤65 μm...

BACKGROUND: Psoriasis is an inflammatory skin disease that affects 2-3% of the worldwide population. The interleukin-17 cytokine family has been proven to play a central role in the pathogenesis of psoriasis. Brodalumab is a novel biologic agent that targets interleukin-17 molecules and their receptors. We aimed to evaluate the safety and efficacy of brodalumab as a therapeutic agent for moderate-to-severe psoriasis in a meta-analysis framework. METHODS: A computer literature search of PubMed, OVID, Cochrane Central, EMBASE, EBSCO, Scopus, and Web of Science was conducted using relevant keywords...

BACKGROUND: Inflammation is an important underlying mechanism in the pathogenesis of atherosclerosis, and an elevated resting heart rate underlies the process of atherosclerotic plaque formation. We hypothesized an association between resting heart rate and subclinical inflammation. METHODS: Resting heart rate was recorded at baseline in the KoGES-ARIRANG (Korean Genome and Epidemiology Study on Atherosclerosis Risk of Rural Areas in the Korean General Population) cohort study, and was then divided into quartiles...

BACKGROUND AND PURPOSE: Magnetic resonance imaging (MRI)-defined carotid plaque hemorrhage (MRIPH) can predict recurrent cerebrovascular ischemic events in severe symptomatic carotid stenosis. It is less clear whether MRIPH can improve risk stratification despite optimized medical secondary prevention in those with moderate risk. METHODS: One-hundred fifty-one symptomatic patients with 30% to 99% carotid artery stenosis (median age: 77, 60.5% men) clinically deemed to not benefit from endarterectomy were prospectively recruited to undergo MRI and clinical follow-up (mean, 22 months)...

Atherosclerosis is the primary cause of coronary heart disease (CHD), ischemic stroke, and peripheral arterial disease. Despite effective lipid-lowering therapies and prevention programs, atherosclerosis is still the leading cause of mortality in the United States. Moreover, the prevalence of CHD in developing countries worldwide is rapidly increasing at a rate expected to overtake those of cancer and diabetes. Prominent risk factors include the hardening of arteries and high levels of cholesterol, which lead to the initiation and progression of atherosclerosis...

BACKGROUND: Chromogranin A (CgA), a circulating protein released by the neuroendocrine system, can regulate vascular physiology and angiogenesis. Full-length CgA (CgA1-439) and its fragment CgA1-76 (called vasostatin-1, VS-1) preserve the physiological integrity of the endothelial barrier function and are antiangiogenic, whereas CgA1-373 is proangiogenic. We investigated whether these polypeptides are altered in patients with various degrees of carotid artery atherosclerosis. METHODS: We studied 81 patients with carotid artery atherosclerosis, asymptomatic for cerebrovascular diseases...

OBJECTIVES: Given the enhanced risk of ischemic stroke resulting from the direct effects of hyperuricemia on vascular plaque formation seen among older males with gout we sought to determine the prevalence of calcified carotid artery atheromas (CCAA) on their panoramic images. METHODS: Medical records librarians identified all male patients over age 45 who had a diagnosis of gout and a panoramic image incidentally obtained between 2000-2015. The prevalence rate of CCAA on technically appropriate images was determined as were these patients' atherogenic risk profiles including: age, BMI, hypertension, dyslipidemia...

BACKGROUND: The Health Action Process Approach (HAPA) model addresses health behaviours, but it has never been applied to model adolescents' oral hygiene behaviour during fixed orthodontic treatment. AIM: This study aimed to apply the HAPA model to explain adolescents' oral hygiene behaviour and dental plaque during orthodontic treatment with fixed appliances. METHODS: In this cross-sectional study, 116 adolescents with fixed appliances from an orthodontic clinic situated in Almere (the Netherlands) completed a questionnaire assessing oral health behaviours and the psychosocial factors of the HAPA model...

Non-obstructive angioscopy (NOA) is used to visualize the surface of the coronary artery, and a clear visual field is obtained by injecting transparent fluid into the gap between the probing catheter and the fiber. This study examines visual field expansion by a dual infusion method, which involves an infusion from the probing and guiding catheters, and the relationships between visual grade and vessel characteristics. Thirty-two patients and thirty patients performed coronary plaque analysis with NOA using the conventional method and the novel dual infusion method, respectively...

BACKGROUND AND AIMS: Coronary computed tomography angiography (CCTA) permits effective identification of diffuse CAD and atherosclerotic plaque characteristics (APCs). We sought to examine the usefulness of diffuse CAD beyond luminal narrowing and APCs by CCTA to detect vessel-specific ischemia. METHODS: 407 vessels (n = 252 patients) from the DeFACTO diagnostic accuracy study were retrospectively analyzed for percent plaque diffuseness (PD). Percent plaque diffuseness (PD) was obtained on per-vessel level by summation of all contiguous lesion lengths and divided by total vessel length, and was logarithmically transformed (log percent PD)...

BACKGROUND: High-density lipoprotein (HDL) is believed to have atheroprotective properties, but an effective HDL-based therapy remains elusive. Early studies have suggested that infusion of reconstituted HDL promotes reverse cholesterol transport and vascular reactivity. The CER-001 Atherosclerosis Regression Acute Coronary Syndrome Trial (CARAT) is investigating the impact of infusing an engineered pre-beta HDL mimetic containing sphingomyelin (SM) and dipalmitoyl phosphatidlyglycerol (CER-001) on coronary atheroma volume in patients with a recent acute coronary syndrome (ACS)...

BACKGROUND: Carotid intima-media thickness (CIMT) has been proposed as a surrogate marker of atherosclerotic disease. In addition, carotid flow velocity (FV) and muscle strength (MS) are reported to be associated with increased CIMT. As there remains insufficient evidence for a complex association of CIMT with FV and MS, the aim of this study was to examine this association in adults. METHODS: A total of 426 adults participated in this study. MS in all subjects was measured by hand grip strength...

Although experimental studies suggest that low and oscillatory wall shear stress (WSS) promotes plaque transformation to a more vulnerable phenotype, this relationship has not been examined in human atherosclerosis progression. Thus, the aim of this investigation was to examine the association between oscillatory WSS, in combination with WSS magnitude, and coronary atherosclerosis progression. We hypothesized that regions of low and oscillatory WSS will demonstrate progression towards more vulnerable lesions, while regions exposed to low and non-oscillatory WSS will exhibit progression towards more stable lesions...

Advanced glycation end-products (AGEs) are increased and predict mortality in patients with chronic kidney disease (CKD) who are undergoing hemodialysis, irrespective of the presence of type 2 diabetes. However, little information exits about the relationship between AGEs and subclinical atherosclerosis at the early stages of CKD. A case-control study was performed including 87 patients with mild-to-moderate stages of CKD (glomerular filtration rate from 89 to 30 ml/min/per 1.73m2) and 87 non-diabetic non-CKD subjects matched by age, gender, body mass index, and waist circumference...
