Early Spontaneous Recanalization of Symptomatic Carotid Occlusion: When Should We Be Looking? (P01.238)
CONCLUSIONS: Spontaneous recanalization of an occluded carotid artery may occur in a subacute fashion. Clinical deterioration, even minor, should prompt an investigation into possible recanalization.Disclosure: Dr. Cutting has received personal compensation for activities with F1000.

Acute absolute vasodilatation is associated with a lower vascular wall stiffness in pulmonary arterial hypertension
Abstract: Background: Acute vasoreactivity testing (VT) is considered mandatory in the diagnostic work-up of patients with pulmonary arterial hypertension (PAH). We studied the relation between the acute absolute arterial vasodilatation and the severity of vascular remodeling estimated by intravascular ultrasound (IVUS) in patients with idiopathic PAH.Methods: Simultaneous right heart catheterization and IVUS of the pulmonary artery (PA) were performed both in basal conditions and during short-term intravenous epoprostenol infusion in nineteen idiopathic PAH patients. Pulmonary vascular resistance (PVRi) and capacitance in...

Left Ventricular Responses to Acute Changes in Late Systolic Pressure Augmentation in Older Adults.
CONCLUSIONS: Acute changes in late systolic aortic pressure augmentation do not necessarily lead to improved systolic or diastolic function in older people. Preload may be a more important determinant of cardiac performance than afterload in older people with compensated ventricular function. The potential for changes in preload to impair rather than enhance left ventricular systolic and diastolic function in older people warrants further study. CLINICAL TRIALS REGISTRATION: This study is registered at clinicaltrials.gov as NCT00204984. PMID: 23537892 [PubMed - as supplied by publisher]

E-006 Familial Incidence of the Congenital Torcular Dural Arteriovenous Shunt
Purpose There are several hereditary disorders that are well known to be associated with arteriovenous malformations (AVMs) involving the central nervous system including Sturge-Weber, Klippel-Trenaunay-Weber, and Parkes-Weber syndromes as well as hereditary haemorrhagic telangiectasia and hereditary neurocutaneous angiomatosis. Furthermore, familial incidence of AVMs in the absence of congenital hereditary disorders also has been reported. Herein, we describe the occurrence of the giant torcular herophili (TH) dural arteriovenous fistula (AVF) in two pediatric cousins treated with endovascular embolization. Case report C...

Association of ultrasonographic parameters with subclinical white-matter hyperintensities in hypertensive patients.
Conclusions. Our study showed that in hypertensive individuals with brain SVD the extent of structural changes in cerebral microcirculation as reflected by WMHs burden is associated with the following ultrasound parameters of cerebral macrocirculation: CCA diameter and MCA-PI.

Carotid velocities determine cerebral blood flow deficits in elderly men with carotid stenosis
Authors: Siennicki-Lantz A, Wollmer P, Elmståhl S Abstract To examine if mild carotid stenosis correlates with silent vascular brain changes, we studied a prospective population-based cohort "Men born in 1914." Data from followups at ages 68 and 81, have been used. Carotid ultrasound was performed at age 81, and cerebral blood flow (CBF) was measured with SPECT at age 82. Out of 123 stroke-free patients, carotid stenosis <50% was observed in 94% in the right and 89% in the left internal carotid arteries (ICAs). In these subjects, Peak Systolic Velocities in ICA correlated negatively with CBF in a majority of se...

Normocalcaemic, vitamin D sufficient hyperparathyroidism ‐ high prevalence and low morbidity in the general population A long‐term follow‐up study, the WHO MONICA project, Gothenburg, Sweden
ConclusionsThis small random population study showed that nHPT was common, 11% at follow‐up. Only one individual developed mild hypercalcaemia in 13 years. Previous S‐PTH was predictive of nHPT and hypertension was prevalent, but no increase in hard end points was seen over a 17‐year period.This article is protected by copyright. All rights reserved.

Cerebral Hemodynamics in the Elderly: A Transcranial Doppler Study in the Einstein Aging Study Cohort
Conclusions— We report a decreased mean blood flow velocity and weakly increased arterial pulsatility and resistance with aging in a large elderly stroke-free population. These referential trends in cerebrovascular hemodynamics may carry important implications in vascular diseases associated with advanced age, increased risk of cerebrovascular disease, cognitive decline, and dementia.

Prevalence and determinants of the increased carotid intima-media thickness in a population of 1203 black African hypertensive.
CONCLUSION: Increased carotid intima-media thickness is frequent in Togolese hypertension. The determining factors are age, duration of arterial hypertension, left ventricular hypertrophy and stroke. The systematic measurement of the carotid intima-media thickness would better evaluate the overall cardiovascular risk for our patients. PMID: 30290917 [PubMed - as supplied by publisher]

Cardiovascular Programming During and After Diabetic Pregnancy: Role of Placental Dysfunction and IUGR
This study demonstrated that the incidence of ischemic heart disease and death were three times higher among men with low birth weight compared to men with high birth weight (5). Epidemiological investigations of adults born at the time of the Dutch famine between 1944 and 1945 revealed an association between maternal starvation and a low infant birth weight with a high incidence of hypertension and coronary heart disease in these adults (23). Furthermore, Painter et al. reported the incidence of early onset coronary heart disease among persons conceived during the Dutch famine (24). In that regard, Barker's findin...

Impact of H-Type Hypertension on Intraplaque Neovascularization Assessed by Contrast-Enhanced Ultrasound
CONCLUSION: H-type hypertension is expressly connected with the degree of plaque enhancement and may facilitate plaque vulnerability. Our findings may offer a new insight for treating vulnerable plaque, lowering blood pressure, and lowering homocysteine equally crucial.PMID:33827997 | DOI:10.5551/jat.61275
