REVIEW
Sara V Greve, Stephan Laurent, Michael H Olsen
In a recently published paper, Greve et al [J Hypertens 2016;34:1279-1289] investigate whether the estimated carotid-femoral pulse wave velocity (ePWV), calculated using an equation derived from the relationship between carotid-femoral pulse wave velocity (cfPWV), age, and blood pressure, predicts cardiovascular disease (CVD) as good as the measured cfPWV. Because ePWV predicts CVD as good as cfPWV, some might wonder whether ePWV could be replaced by cfPWV, which is a time-consuming measurement requiring an expensive apparatus...

Vascular stiffness is a key physiological marker significant in screening and early diagnosis of vascular disease. However, state of art techniques for vascular stiffness evaluation are not suited for field deployment. We present ARTSENS(®) Mobile, a portable, image-free ultrasound technology platform for automated evaluation of carotid artery stiffness, amenable for field deployment. The technology utilises a single element ultrasound transducer operated in pulse echo modality to investigate arterial wall dynamics, assisted by intelligent algorithms for wall identification and motion tracking to completely automate the measurement...

: Diabetes mellitus (diabetes) is associated with significantly increased risk of peripheral vascular disease. Diabetes is classified as a coronary heart disease (CHD) risk equivalent, but it is unknown whether diabetes is a CHD risk equivalent for peripheral vascular disease. The objective was to evaluate the odds of peripheral arterial disease (PAD) or carotid artery stenosis (CAS) among participants with diabetes, CHD, or both, compared with participants without diabetes or CHD, in a nationwide vascular screening database...

Prehypertension and hypertension in childhood are defined by sex-, age-, and height-specific 90th (or ≥120/80 mm Hg) and 95th percentiles of blood pressure, respectively, by the 2004 Fourth Report. However, these cutoffs are complex and cumbersome for use. This study assessed the performance of a simplified blood pressure definition to predict adult hypertension and subclinical cardiovascular disease. The cohort consisted of 1225 adults (530 men; aged 26.3-47.7 years) from the Bogalusa Heart Study with 27...

Background -Relative risk reduction with statin therapy has been consistent across nearly all subgroups studied to date. However, in analyses of two randomized controlled primary prevention trials (ASCOT and JUPITER), statin therapy led to a greater relative risk reduction among a subgroup at high genetic risk. Here, we sought to confirm this observation in a third primary prevention randomized controlled trial. Additionally, we assessed if those at high genetic risk had a greater burden of subclinical coronary atherosclerosis...

BACKGROUND: Validation of subclavian duplex ultrasound velocity criteria (SDUS VC) to grade the severity of subclavian artery stenosis has not been established or systematically studied. Currently, there is a paucity of published literature and lack of practitioner consensus for how subclavian duplex velocity findings should be interpreted in patients with subclavian artery stenosis. OBJECTIVE: The objective of the present study was to validate SDUS measurements using subclavian conventional or computed tomography angiogram (subclavian angiogram [SA])-derived measurements...

Moyamoya disease is characterized by bilateral progressive terminal internal carotid arteries steno-occlusion. In this patient, the disease affected middle cerebral arteries and was disclosed after a left frontal cerebral infarction. Brain HMPAO perfusion scintigraphy with acetazolamide challenge, obtained before surgical treatment, demonstrates an extended bilateral frontal hypoperfusion with a vascular steal phenomenon. The same examination obtained after surgical treatment demonstrates a frank improvement in basal brain vascularization, with nearly complete correction of vascular steal phenomenon...

Carotid artery plaques with high-signal intensity on T1 weighted image (T1 WI) are known to cause cerebral ischemic disease. Signal intensity ratio (SIR), which is calculated from T1 WI in the quantitative evaluation of plaque characterization have been used. However, the various sequences in T1 WI and difference in the sequences were utilized among institutions. Therefore, difference in sequence may influence SIR. The purpose of this study was to evaluate the optimization of T1 WI sequence in MR carotid plaque imaging...

BACKGROUND: Aortic arch disease is a challenging clinical problem, especially in high-risk patients, in whom open repair can have morbidity and mortality rates of 30% to 40% and 2% to 20%, respectively. Aortic arch chimney (AAC) stents used during thoracic endovascular aortic repair (TEVAR) are a less invasive treatment strategy than open repair, but the current literature is inconclusive about the role of this technology. The focus of this analysis is on our experience with TEVAR and AAC stents...

OBJECTIVE: Cardiovascular disease (CVD) caused by atherosclerosis remains a worldwide burden. Hydrogen sulfide is a promising new therapeutic avenue for the treatment of CVD, however reports show exogenous H2S has both vasodilator and vasoconstrictor effects depending on organ examined, and in vitro studies in animal models which are not resistant to developing atherosclerosis are limited. We sought to determine if rabbit arteries constricted or dilated to hydrogen sulfide. MATERIAL AND METHODS: The aorta, carotid, renal and iliac arteries were harvested from New Zealand White rabbits (n=4) and subjected to a concentration response curve to the fast H2S releaser NaHS...

Retinal ischemia is a condition associated with retinal degenerative diseases such as glaucoma, diabetic retinopathy, and other optic neuropathies, leading to visual impairment and blindness worldwide. Currently, there is no therapy available for ischemic retinopathies. Therefore, the aim of this study was to test a murine model of pterygopalatine artery ligation-induced retinal injury for transplantation of mouse bone marrow-derived lineage-negative (lin-ve) stem cells. The mouse external carotid artery and pterygopalatine artery were ligated for 3...

Accumulation of visceral fat leads to metabolic syndrome and increases risks of cerebro-cardiovascular diseases, which should be recognized and improved at the early stage in general population. Accurate measurement of visceral fat area (VFA) is commonly performed by the abdominal cross-sectional image measured by computed tomography scan, which is, however, limited due to the radiation exposure. The bioelectrical impedance analysis (OMRON, HDS-2000 DUALSCAN(R)) has been recently developed to measure VFA, which is more easily accessible modality...
