Abstract BACKGROUND: Hypertensive urgencies (HypUrg) are define as severe elevation in blood pressure (BP) without acute target organ damage (TOD). In the office setting, treated asymptomatic patients, with severe BP elevation meeting criteria for urgency are often seen. We evaluate incident CV events (fatal and non-fatal stroke or acute myocardial infarction, TIA, coronary or carotid revascularization, atrial fibrillation (n=311)) during follow-up (FU) in patients with HypUrg at first outpatient visit. METHODS: From the Campania Salute Network (CSN) Registry. HypUrg was define by systolic BP ≥180mmHg and/...

Prolonged neonatal oxygen exposure causes persistent aortic structural and biomechanical alterations, which was even more pronounced after recovery in normoxia. This was accompanied by a marked impairment in left ventricular function. These findings have important implications as it suggests that premature babies exposed to oxygen may be predisposed to vascular dysfunction, leading to increased risk of cardiovascular disease in later life. As this affected population begins to age, there will be a critical need to identify the underlying pathophysiological mechanisms for these vascular morbidities in preterm survivors. Abs...

CONCLUSIONS: Of cases with redundant neurovascular imaging, most were generated by clinicians, but radiologists recommended redundant neurovascular imaging in 17.6% of patients; 81.8% occurred following MRA. Overall, most secondary studies (68.8%) confirmed the findings of the first study. Such low-value, same-result redundant neurovascular imaging was more common when clinicians ordered the studies (73.8%) than when radiologists ordered them (54.6%).

AbstractIntroductionTo improve the accuracy of ultrasound techniques for the assessment of carotid stenosis, we designed a novel carotid artery stenosis ultrasound scale (CASUS), and evaluated its accuracy, reliability, and its value in predicting the occurrence of cardiovascular and cerebrovascular diseases in a prospective study.MethodsA total of 750 patients with first-time ischemic stroke and hospitalized within 24  h were enrolled in the study. Using color Doppler ultrasound (CDUS), the degree of stenosis and blood flow (BF) in bilateral internal carotid arteries (ICA) and the V1-V3 segment of vertebral arteries ...

Introduction: Successful thrombectomy improves morbidity and mortality after stroke. The present prospective, observational cohort study investigated a potential correlation between the successful restoration of tissue perfusion by mechanical thrombectomy and intact cerebrovascular autoregulation (CA). Objective: Status of CA in patients with large vessel occlusive stroke after thrombectomy. Methods: After thrombectomy CA was measured using transcranial Doppler ultrasound. For this purpose a moving correlation index (Mxa) based on spontaneous arterial blood pressure fluctuations and corresponding cerebral blood flow veloci...

Conclusions: At least 27 pediatric neurocritical care centers use transcranial Doppler during clinical care. In the majority of centers, studies are performed and interpreted by credentialed personnel, and findings are used to guide clinical management. Further studies are needed to standardize these practices.

Introduction Glenohumeral subluxation (GHS) is commonly reported in people with stroke. Lycra sleeves provide a compressive and supportive effect, influencing the neuromuscular activity in the affected body segment. A recent study reported reduction in GHS (acromion-greater tuberosity [AGT] distance) after application of Lycra arm sleeve; however, its mechanism on the shoulder region as a whole is unclear. The aim of this study was to investigate if application of a Lycra sleeve changes the AGT distance, muscle activity around the shoulder region, and scapular position. Methods Healthy participants aged older than 18 ...

BaileyAbstractFemales are more prone to cognitive decline, stroke and neurodegenerative disease, possibly due to more marked reductions in cerebral blood flow and cerebrovascular reactivity to CO2 (CVRCO2HYPER) in later life. To what extent regular exercise confers selective neuroprotection in females remains unestablished. To examine this, 73 adults were prospect...

Background: Little is known on factors influencing cognitive function in rural communities. Using the Atahualpa Project cohort, we aimed to assess whether the carotid intima-media thickness (cIMT) – used as a surrogate of extracranial carotid atherosclerosis – is associated with cognitive performance and further decline in community-dwelling adults living in a rural setting. Methods: The study included Atahualpa residents aged greater than or equal to 40 years who had ultrasound examinati on of the extracranial carotid arteries and a baseline Montreal Cognitive Assessment (MoCA), as well as the subset of indivi...
