Abstract
BACKGROUND Atherosclerosis (AS) is a multifocal, smoldering immune inflammatory disease of medium and large arteries driven by lipids. The aim of this study is to discuss the mechanism of microRNA-146a-3p (miR-146a-3p)/histone deacetylase 1 (HDAC1)/Krüppel-like factor 5 (KLF5)/inhibitors of kappa B α (IKBα) signal axis in plaque formation of AS mice. METHODS ApoE-/- mice were fed with high-fat feed for 12 weeks to establish AS mice model. The expression of miR-146a-3p, KLF5, HDAC1 and IKBα in aortic wall tissues of AS mice was tested. The targeting relationship between miR-146a-3p and HDAC1 was verified. AS mice were injected with miR-146a-3p antagomir or HDAC1 overexpression to verify the impacts of miR-146a-3p and HDAC1 on blood lipids and inflammatory factors in serum, aortic wall apoptotic cells, antioxidant stress capacity and the plaque area in AS mice. VECs proliferation and apoptosis were also measured in vitro. RESULTS miR-146a-3p and KLF5 were increased while HDAC1 and IKBα were reduced in aortic wall tissues of AS mice. miR-146a-3p directly targeted to HDAC1. Depletion of miR-146a-3p or restoration of HDAC1 was correlated to lower plasma lipid level, reduced inflammatory factors in serum, attenuated aortic wall apoptosis, increased antioxidant stress capacity and improved the stability of pathological plaque of AS mice. miR-146a-3p down-regulation or HDAC1 up-regulation promoted VECs proliferation and inhibited apoptosis. CONCLUSION Functional studies show that depleted miR-146a-3p advances HDAC1 and IKBα expression as well as inhibits KLF5 expression to facilitate the stability of pathological plaques in AS mice.

Abstract
BACKGROUND Drug eluting stent (DES) remain several problems, including stent thrombosis, stent fracture and neoatherosclerosis. Stent-less Percutaneous coronary intervention (PCI) using a drug coated balloon (DCB) is a stent-less strategy, and several trials have supported the efficacy of DCB. However, the optimal preparation before using DCB was uncertain. The aim of this study was to investigate the optimal preparation for plaque oppression/debulking before DCB dilatation for de novo coronary artery lesion. METHODS A total 936 patients were treated using DCB from 2014 to 2017 at our institution. Among them, we analyzed 247 patients who underwent PCI using DCB alone for de novo lesion. The primary end point of this study was target lesion failure (TLF). RESULTS The area under the receiver operating characteristic (ROC) curve (AUC) was used to determine the optimal cutoff value of % plaque area to predict TLF. ROC curve analysis revealed plaque area ≥ 58.5% (AUC, 0.81) were associated with TLF. Eligible 188 patients were divided into 2 groups (plaque area ≥ 58.5% [n = 38] and <58.5% [n = 150]) according to IVUS data before using DCB. TLF was significantly higher in plaque area ≥ 58.5% group than in <58.5% group (P < 0.01). Multivariable analysis selected plaque area ≥ 58.5% as an independent predictor of TLF (hazard ratio 7.59, P < 0.01). CONCLUSIONS Lesion preparation achieving plaque area < 58.5% was important in stent-less PCI using DCB.

Abstract
INTRODUCTION AND OBJECTIVES There is a discrepancy between risk assessment based on cardiovascular risk factors (CVRF) and atheromatosis burden. The objective was to identify the prevalence of subclinical diseases with common risk factors, such as atheromatosis, occult kidney disease, prediabetes, and diabetes in a middle-aged population with low-to-moderate cardiovascular risk; to assess the vascular distribution, and severity of subclinical atheromatosis. METHODS Randomized, interventional, longitudinal clinical trial. The intervention consisted of vascular ultrasound examination in the carotid and femoral arteries assessing 12 territories, combined with clinical, anthropometric, lifestyle, and biochemical parameters. Inclusion criteria consisted of women (aged 50-70 years) and men (aged 45-65 years) with at least 1 CVRF. Exclusion criteria consisted of a clinical history of diabetes, chronic kidney disease, or a prior CV event. Here, baseline characteristics of the ILERVAS cohort are shown. RESULTS A total of 8330 middle-aged asymptomatic participants, 50.7% women, were enrolled. The presence of 1-2 CVRF was found in 74.8% and adherence to the Mediterranean diet was low in 52.8%. Several previously unknown chronic diseases were diagnosed, such as dyslipidemia (21.1%), hypertension (15.3%), kidney disease (15.4%), obesity (10.6%), and diabetes (2.3%). Subclinical atheromatosis was found in 71.4% of participants, localized in common femoral (54.5%), carotid bifurcation (41.1%) and internal carotid (22%). Intermediate atheromatosis (2-3 territories with atheroma plaque) was found in 32.6%, and generalized atheromatosis (>3 territories) in 19.7. Total plaque area was higher in men (0.97 cm2 vs 0.58 cm2, P<.001). Total plaque area was also higher in the femoral artery, and increased with the number of CVRF. CONCLUSIONS Subclinical atheromatosis was highly prevalent in a middle-aged population with low-to moderate cardiovascular risk, with 1 in 5 participants having generalized atheromatosis. ClinicalTrials.gov Identifier: NCT03228459.

Abstract
MOTIVATION The early screening of cardiovascular diseases (CVD) can lead to effective treatment. Thus, accurate and reliable atherosclerotic carotid wall detection and plaque measurements are crucial. Current measurement methods are time-consuming and do not utilize the power of knowledge-based paradigms such as artificial intelligence (AI). We present an AI-based methodology for the joint automated detection and measurement of wall thickness and carotid plaque (CP) in the form of carotid intima-media thickness (cIMT) and total plaque area (TPA), a class of AtheroEdge™ system (AtheroPoint™, CA, USA). METHOD The novel system consists of two stages, and each stage comprises an independent deep learning (DL) model. In Stage I, the first DL model segregates the common carotid artery (CCA) patches from ultrasound (US) images into the rectangular wall and non-wall patches. The characterized wall patches are integrated to form the region of interest (ROI), which is then fed into Stage II. In Stage II, the second DL model segments the far wall region. Lumen-intima (LI) and media-adventitial (MA) boundaries are then extracted from the wall region, which is then used for cIMT and PA measurement. RESULTS Using the database of 250 carotid scans, the cIMT error using the AI model is 0.0935±0.0637 mm, which is lower than those of all previous methods. The PA error is found to be 2.7939±2.3702 mm2. The system's correlation coefficient (CC) between AI and ground truth (GT) values for cIMT is 0.99 (p < 0.0001), which is higher compared with the CC of 0.96 (p < 0.0001) shown by the earlier DL method. The CC for PA between AI and GT values is 0.89 (p < 0.0001). CONCLUSION A novel AI-based strategy was applied to carotid US images for the joint detection of carotid wall thickness (cWT) and plaque area (PA), followed by cIMT and PA measurement. This AI-based strategy shows improved performance using the patch technique compared with previous methods using full carotid scans.

Abstract
Approximately, 70 % of acute myocardial infarctions are known to develop from mild atherosclerotic lesions. Therefore, it is important to evaluate mild coronary plaques to prevent acute coronary syndrome (ACS). The aim of the present study was to investigate the effects of exercise-based cardiac rehabilitation (CR) on mild coronary atherosclerosis in non-culprit lesions in patients with ACS. Forty-one men with ACS who underwent emergency percutaneous coronary interventions and completed a 6-month follow-up were divided into CR and non-CR groups. Quantitative coronary angiography (QCA) was performed using the automatic edge detection program. The target lesion was a mild stenotic segment (10-50 % stenosis) at the distal site of the culprit lesion, and the segment to be analyzed was determined at a segment length ranging from 10 to 15 mm. The plaque area was significantly decreased in the CR group after 6 months, but was significantly increased in the non-CR group (P < 0.05). The low-density lipoprotein (LDL) cholesterol, LDL/high-density lipoprotein (HDL) ratio and high-sensitivity C-reactive protein (Hs-CRP) levels were significantly reduced in both groups (P < 0.01). Peak VO2 in the CR group was significantly increased (P < 0.01). Changes in the plaque area correlated with those in Hs-CRP in both groups, while that association with those in HDL-C was observed in only CR group. Stepwise regression analysis revealed the decrease in Hs-CRP as an independent predictor of plaque area regression in the CR group. CR prevented the progression of mild coronary atherosclerosis in patients with ACS.

Abstract
BACKGROUND We aimed to explore the association between presence and number of components of the Metabolic Syndrome (MetS) and subclinical atherosclerosis outcomes (common carotid intima media thickness, plaque presence and sum of plaque area) in both the carotid and femoral bifurcations. METHODS Cross-sectional analysis of 771 volunteers from the ongoing epidemiological Cyprus Study (46% male; mean age = 60.1 ± 9.8). (a) Carotid intima-media thickness (IMTcc), (b) sum of plaque area in the carotid bifurcations (sum of the largest plaques in each carotid bifurcation-SPAcar), (c) sum of plaque area in the femoral bifurcations (sum of the largest plaques in each femoral bifurcation-SPAfem) and (d) sum of plaque area in both carotid and femoral bifurcations (sum of the areas of the largest plaques present in each of the four bifurcations-SPA) were measured at baseline using ultrasound. Presence and number of components of the MetS was ascertained using the National Cholesterol Education Program ATPIII definition and their association tested using multivariable regression models. RESULTS MetS was present in 259 (33.6%) individuals and was associated with a 0.02 mm increase in IMTcc (95% CI: 0.00 to 0.04, p = 0.047) after adjustment for age, sex, family history of CVD, alcohol consumption (BU/week) and smoking (pack-years). Each additional component of the MetS was associated with a 16% higher SPA (95% CI: 6.8% to 25.2%, pfor trend = 0.001), a 10% higher SPAcar (95% CI: 5% to 24%, pfor trend = 0.003) and a 14% higher SPAfem in the adjusted model. CONCLUSIONS We confirm an association between the MetS and IMTcc as well as report for the first time an association between the MetS and its components and femoral plaque area, in a general population over 40 years of age. Having any risk factors for the MetS increases the risk for subclinical atherosclerosis, with the risk increasing with each additional component. Using the dichotomous definition of the MetS may be overlooking the risk for subclinical atherosclerosis -and by inference future cardiovascular events- associated with having less than 3 risk factors.
