Ultrasonographic measurements of the intima-media thickness (IMT) of common carotid arteries (CCA) were taken in 50 patients with familial hypercholesterolaemia (FH) and 57 patients with non-familial hypercholesterolemia (NFH). The lipid profile, body mass index (BMI) and waist-hip ratio (WHR) of each patient were recorded. In FH patients, the IMT was ...

Research investigating the benefits of carotid endarterectomy (CEA) on cognitive functioning remains inconclusive. This study sought to determine what patient characteristics affect cognitive functioning and whether changes in cognitive functioning occur following surgery after controlling for these characteristics. In a prospective longitudinal study, 39 patients scheduled for CEA surgery underwent ...

Increased levels of the gliofibrillar S100b protein can be detected during carotid endarterectomy (CEA). Whether the S100b protein increase is marker of brain ischemic sufferance and predictor of cognitive decline is controversial. Twenty-eight patients underwent clinical assessment and cranial computed tomography (CT) 24-48 hours before and 3 months after CEA. ...

Atherosclerotic diseases are thought to be less frequent in Asians compared with Caucasians. Unlike Caucasians, nearly half of Asians have a functional deficiency in the low Km aldehyde dehydrogenase (ALDH2), a key enzyme in alcohol metabolism, which potentially modifies the prevalence of atherosclerosis. This study examined the associations between ALDH2 ...

Carotid artery stenting (CAS) has been recommended as an alternative to carotid endarterectomy (CEA) by some clinicians. However, recently published clinical trials have reported 30-day stroke and death rates of 10% to 12%. This prompted review of our experience with CAS in patients at high risk, to document our results ...

METHODS: Thirty-eight ...
Goncalves, Isabel
Background and Purpose-Many processes involved in the pathogenesis of atherosclerosis result in modifications of the extracellular matrix. These changes not only determine the mechanical stability of atherosclerotic lesions but can directly or indirectly influence further development of the lesions. The purpose of the present study was to compare the matrix ...

BACKGROUND: Previous limited observations have suggested that atherosclerosis may affect the distensibility of the carotid sinus and then impair the baroreflex sensitivity (BRS). No studies have been done to compare the BRS and heart rate variability (HRV) in patients with carotid stenosis and normal controls. METHODS: A convenience-consecutive sample of ...

The objective of this study was to evaluate the safety and efficacy of carotid artery stenting (CAS) in high-risk patients. Carotid endarterectomy (CEA) has been shown to be more effective than medical therapy but has limitations. CAS may be a reasonable alternative, particularly in high-risk patients. The authors evaluated prospectively ...

The annual risk of stroke in patients with symptomatic carotid artery occlusion (CAO) and impaired cerebral blood flow (CBF) is approximately 10%. Increased oxygen extraction fraction measured by positron emission tomography (PET) and low cerebrovascular reactivity assessed by transcranial Doppler is associated with an increased risk of recurrent ischemic stroke ...
Sheehan Maureen K - - 2002
BACKGROUND: Stroke after carotid endarterectomy (CEA) may be a result of intraoperative ischemia, embolism, or thrombosis at the operative site. Intraoperative duplex should eliminate the occurrence of a severe internal carotid artery (ICA) thrombosis and, thus, negate the benefit of reoperation. This article will detail the results of our evolving ...
