AIMS: Detection of early-stage atherosclerosis in type 2 diabetes mellitus (T2DM) patients is important for preventing cardiovascular disease. A phased tracking method for evaluating arterial wall elasticity sensitively detects early-stage atherosclerosis. However, biochemical markers for early-stage atherosclerosis have yet to be established. METHODS: This cross-sectional study enrolled 180 T2DM patients, who were classified as not having atherosclerosis according to the carotid intima-media thickness (IMT) criteria...

Arteriovenous malformations consist of tangles of arteries and veins that are often connected by a fistula. The causes and mechanisms of these clinical entities are not fully understood. We discovered that suturing an arterial patch into the common jugular vein of rabbits led to spontaneous neovascularization, the formation of an arteriovenous fistula and the development of an arteriovenous shunt. An arterial patch excised from the common carotid artery was sutured into the common jugular vein. Within a month, a dense nidus-like neovasculature formed around the patch...

Background -Obesity plays crucial roles in the development of cardiovascular diseases (CVDs). However, the mechanisms that link obesity and CVDs remain elusive. Compelling evidence indicates that adipokines play an important role in obesity-related CVDs. Here, we found a new adipokine named family with sequence similarity 19, member A5 (FAM19A5), a protein with unknown function that was predicted to be distantly related to the CC-chemokine family. We aimed to test whether adipose-derived FAM19A5 regulates vascular pathology upon injury...

OBJECTIVE: Idiopathic Parkinson's disease (IPD) is the second most common neurodegenerative disorder, often complicated by dementia. Cardiovascular risk factors and spontaneous cerebral emboli (SCE) are strongly associated with Alzheimer's (AD) and vascular dementia (VaD). We measured SCE in the middle cerebral artery and arterial wall volume in the extracranial arteries in patients with IPD and controls, and explored the relationships with structural and physiological MRI brain neurovascular measures...

Hypoglossal nerve palsy (HNP) is a common finding in neurologic diseases when associated with other cranial nerve palsies or further pathology and exhibits characteristic clinical manifestations, including unilateral atrophy of the musculature of the tongue. It occasionally appears as the initial or solitary sign of an intracranial or extracranial space-occupying lesion, head or neck injury, or vascular abnormality of the internal carotid artery. There are few cases of idiopathic isolated unilateral HNP, which should be diagnosed through exclusion...

The concomitance between coronary artery disease and carotid artery disease is known and well documented. However, it is a fact that, despite the screening methods for these conditions and the advances in surgical treatment, little has been achieved in terms of reducing the risk of complications in the perioperative period. Publications are scarce, being mostly composed of reports or case series. There is little agreement on the best initial therapeutic approach (myocardial versus carotid revascularization) or the best technique to be used (surgery with or without extracorporeal circulation, hybrid treatments, etc...

Ernesto L Schiffrin
Gupta et al. [Cell 2017; 170: 522-533] have shown that a genetic variant associated with the 5 vascular diseases is a distal regulator of endothelin (ET)-1 gene (EDN1) expression. A common single nucleotide polymorphism (SNP) in the third intron of the PHACTR1 gene, rs9349379, is the potential variant responsible for increased risk of coronary artery disease, and lower risk of migraine, carotid dissection, fibromuscular dysplasia, and hypertension. Since ET-1 acts through ET type B receptors (ETBR) on endothelial cells to stimulate the production of nitric oxide and prostacyclin and induce vasodilation, this may contribute to these findings...

Arterial stiffening is a hallmark of the aging process and atherosclerosis, including peripheral arterial disease (PAD). We investigated the associations between carotid-femoral pulse wave velocity (c-fPWV), augmentation index corrected for heart rate (Aix@HR75), ankle brachial index (ABI), and subendocardial viability ratio (SEVR), an indicator of cardiac perfusion. The c-fPWV, Aix@HR75, and SEVR was estimated using applanation tonometry. The ankle systolic pressure measurements for the calculation of the ABI were obtained using an 8-mHz Doppler probe...

AIM: It remains unclear whether measures used in carotid ultrasonography such as the intima-media thickness (IMT) and ultrasonic tissue characterization of the carotid using the gray-scale median (GSM) can add prognostic information beyond the conventional cardiovascular risk markers in patients with diabetes. METHODS: This study employed a combined analysis of data obtained in five longitudinal studies including a total of 3263 patients with diabetes but without apparent cardiovascular disease (CVD) at baseline...

Internal carotid arterial system is the main source of blood supply in brain. In forensic identification practice, blunt injures of internal carotid arterial system usually cause complications such as thrombus, aneurysm and arteriovenous fistula, etc. The deaths following delayed cerebral infarction or intracranial haemorrhage are not rare. At present, literature of deaths caused by blunt injuries of internal carotid arterial system mainly consist of case reports in China. This paper reviews related literature and case reports at home and abroad, and summarizes forensic medical features and identification method of the deaths caused by such injuries...

BACKGROUND AND PURPOSE: A recurrent duplication of chromosome 16p13.1 was associated with aortic dissection as well as with cervical artery dissection. We explore the segregation of this duplication in a family with familial aortic disease. METHODS: Whole exome sequencing (WES) analysis was performed in a patient with a family history of aortic diseases and ischemic stroke due to an aortic dissection extending into both carotid arteries. RESULTS: The index patient, his affected father, and an affected sister of his father carried a large duplication of region 16p13...

OBJECTIVE: HIV is a cardiovascular disease (CVD) risk factor. However, CVD risk is often underestimated in HIV-infected women. C-reactive protein (CRP) may improve CVD prediction in this population. We examined the association of baseline plasma CRP with subclinical CVD in women with and without HIV. DESIGN: Retrospective cohort study. METHODS: A total of 572 HIV-infected and 211 HIV-uninfected women enrolled in the Women's Interagency HIV Study underwent serial high-resolution B-mode carotid artery ultrasonography between 2004 and 2013 to assess carotid intima-media thickness (CIMT) and focal carotid artery plaques...

Ankylosing spondylitis (AS) is associated with an increased risk of atherosclerotic cardiovascular disease (ACD). The atherogenic index of plasma (AIP), which is the logarithmic transformation of the plasma triglyceride (TG) level to the high-density lipoprotein level (HDL) ratio, has been suggested to be a novel marker in the identification of atherosclerosis risk. Therefore, this study aims to determine if the AIP can act as an accurate marker for the detection of subclinical atherosclerosis. Fifty-two male patients with AS and 52 age-, gender-, and body mass index (BMI)-matched healthy control subjects were included in the study...

Fetal-type posterior cerebral artery (FTP) is a common anatomic variation that is closely associated with intracranial aneurysm. In the present study, multislice computed tomography angiography (CTA) was performed to assess whether FTP is a risk factor for intracranial aneurysm. CTA data of 364 consecutive cases of patients who were suspected with cerebrovascular disease or intracranial aneurysm of intracranial artery from 2013 to 2016 were reviewed and the incidence rates of FTP, other variations of the circle of Willis, intracranial aneurysm and FTP with intracranial aneurysm were evaluated...

BACKGROUND: Small dense low density lipoprotein-cholesterol (sdLDL-C), cholesterol ratios and carotid-femoral pulse wave velocity (cf-PWV) impart risk for all-cause morbidity and mortality independently of conventional cardiovascular disease (CVD) risk factors. This study was designed to identify feasible indicators for predicting arterial stiffness progression. METHODS: We followed up 816 normotensive participants without diabetes or CVD for nearly 5.0 years. Cholesterol parameters, ratios and other clinical and laboratory data were collected at baseline...

BACKGROUND AND AIMS: Alpha-1 antitrypsin (A1AT) is the most abundant serine protease inhibitor in human blood and exerts important anti-inflammatory and immune-modulatory effects. In combination with smoking or other long-term noxious exposures such as occupational dust and fumes, genetic A1AT deficiency can cause chronic obstructive pulmonary disease, a condition with elevated cardiovascular risk. The effects of A1AT deficiency on cardiovascular risk have hardly been studied today. METHODS: Using data from 2614 adults from the population-based SAPALDIA cohort, we tested associations of serum A1AT and SERPINA1 mutations with carotid intima-media thickness (CIMT, measured by B-mode ultrasonography) or self-reported arterial hypertension or cardiovascular disease in multiple regression models using a Mendelian Randomization like analysis design...

Severe angio-obliterative pulmonary vascular disease (PAH) remains a disease characterized by great morbidity and shortened survival. Unfortunately, the only currently available treatments for angio-obliterative changes are palliative in the form of pulmonary vasodilators evolving from the phosphodiesterase inhibitor sildenafil to endothelin receptor antagonist: Bosentan; while the only definitive treatment is lung transplantation which remains dependent on the availability of donors and the transplant policies which vary widely from a country to another...

Background -Nitrates are widely used to treat coronary artery disease, but their therapeutic value is compromised by nitrate tolerance, owing to the dysfunction of prostaglandin I2 synthase (PTGIS). Micro RNAs (miRNAs) repress target gene expression and are recognized as important epigenetic regulators of endothelial function. The aim of this study was to determine whether nitrates induce nitrovasodilator resistance via microRNA-dependent repression of PTGIS gene expression. Methods -Nitrovasodilator resistance was induced by nitroglycerin (GTN; 100 mg/kg/day, 3 days) infusion in Apoe-/- mice...
