Formation and growth of atherosclerotic plaques have serious clinical consequences. One mechanism that occurs during atherogenesis is migration of smooth muscle cells from the middle layer of the artery to the intima, where they proliferate and are transformed into foam cells. This degenerative process is accompanied by glycation, by which proteins are modified and change the biomechanical and biochemical properties. The aim of the study was to determine whether glycation of collagen and elastin building the walls of blood vessels alters the adhesion and rate of myocyte migration...

Baofeng Xu, Rui Liu, Liqun Jiao, Jinlu Yu
It is relatively difficult to treat restenosis when restenosis occurs following carotid artery stenting. Endarterectomy with simultaneous stent removal is an effective approach when restenosis occurs. The treatment method is still not well known. The present paper reports a case of restenosis after stenting that was treated with endarterectomy with a satisfactory treatment outcome. The patient, a 74-year-old male, underwent stenting 10 months before he was re-hospitalized. He seemed to recover well after stenting until one month before he was re-hospitalized, when he presented symptoms of cerebral ischemia...

Aortic dissection is diagnostically challenging, especially in pain-free patients. Detection of acute ischemic stroke secondary to painless aortic dissection is a challenge for emergency physicians and neurologists. We report a previously healthy 58-years old female, admitted because of nausea, dizziness, somnolence, a left-sided hemiparesis and arterial hypotension. The electrocardiogram showed atrial fibrillation with ST-elevations and ST-depressions. Perfusion CT-imaging showed a dilatation of the aortic arch and intraluminal structures indicating an intima flap of aortic dissection...

PURPOSE: Bariatric surgery (BS) promotes carotid intima-media thickness (C-IMT) regression as early as 6 months post-surgery. To verify whether C-IMT regression occurs even earlier, we aimed at the effect of Roux-en-Y gastric bypass (RYGBP) and biliopancreatic diversion (BPD) on C-IMT 1-2 months and 12 months post-surgery. SUBJECTS/METHODS: Prospective trial. BS was performed on 109 patients either with (RYGBP = 42; BDP = 40) or without type 2 diabetes (RYGBP = 27)...

AIM: Limited joint mobility (LJM) of hand, which is one of a complication of diabetic hand, has a close association with diabetic microangiopathy. However, it remains to be elucidated about the relationships between LJM of hand and subclinical atherosclerosis in patients with type 2 diabetes. Therefore, we conducted a cross-sectional study to evaluate the relationships between LJM of hand and carotid intima-media thickness (IMT) and plaque score in patients with type 2 diabetes. METHODS: We evaluated the relationships between LJM of hand, and carotid IMT and plaque score, evaluated by carotid ultrasound examination, in 341 consecutive patients with type 2 diabetes...

PURPOSE: Quantitative and automatic analysis of intracoronary optical coherence tomography images is useful and time-saving to assess cardiovascular risk in the clinical arena. METHODS: First, the interfaces of the intima, media, and adventitia layers are segmented, by means of an original front propagation scheme, running in a 4D multi-parametric space, to simultaneously extract three non-crossing contours in the initial cross-sectional image. Second, information resulting from the tentative contours is exploited by a machine learning approach to identify healthy and diseased regions of the arterial wall...

BACKGROUND: Since neointima smooth muscle cells (SMC) mainly originate from the vessel wall, we investigated whether atherosclerotic plaque composition influences subsequent in-stent neointima proliferation and restenosis. METHODS: We performed intravascular ultrasound (IVUS) with virtual histology in 98 patients prior to elective bare-metal stent (BMS) implantation in de novo coronary artery lesions. Virtual histology variables pre-percutaneous coronary intervention (PCI) were related to in-stent neointima proliferation six months after implantation assessed as late luminal loss of 0...

PURPOSE: Vitamin B deficiency has been identified as a risk factor for vascular events. However, the reduction of vascular events was not shown in large randomized controlled trials evaluating B-Vitamin therapy. There is an important requirement to develop sensitive biomarkers to be used as efficacy targets for B-Vitamin therapy as well as other dietary treatments and lifestyle regimes that are being developed. Carotid vessel-wall-plus-plaque thickness change (VWT-Change) measured from 3D ultrasound has been shown to be sensitive to atorvastatin therapies in previous studies...

Increased carotid intima-media thickness (IMT) in individuals without hypertension might indicate other factors promoting the atherosclerotic process that are often simultaneously clustered in individuals. The present study tested the hypothesis that carotid IMT predicts new onset of hypertension in the normotensive subjects.A total of 867 participants were enrolled from our yearly physical checkup program and their carotid IMT was measured. After a baseline examination, the subjects were followed up for a median of 1091 days with the endpoint being the development of hypertension...

BACKGROUND AND OBJECTIVES: Systemic inflammation has an important role in the initiation of atherosclerosis, which is associated with arterial stiffness (AS). Aortic flow propagation velocity (APV) is a new echocardiographic parameter of aortic stiffness. The relationship between systemic inflammation and AS has not yet been described in patients with familial Mediterranean fever (FMF). We aimed to investigate the early markers of AS in patients with FMF by measuring APV and carotid intima-media thickness (CIMT)...

Valvular heart disease frequently occurs as a consequence of premature atherosclerosis in individuals with familial hypercholesterolemia (FH). Studies have primarily focused on aortic valve calcification in heterozygous FH, but there is paucity of data on the incidence of valvular disease in homozygous FH. We performed echocardiographic studies in 33 relatively young patients (mean age: 26 years) with homozygous FH (mean LDL of 447 mg/dL, 73% on LDL apheresis) to look for subclinical valvulopathy. Twenty-one patients had evidence of valvulopathy of the aortic or mitral valves, while seven subjects showed notable mitral regurgitation...
