An in vitro preparation of rabbit aortic "intima-media" previously shown to exhibit stable rates of respiration and glucose metabolism and the high rate of aerobic glycolysis considered characteristic of the metabolism of this tissue was subjected to electron microscopic examination. In samples examined immediately after the aortae were dissected free of adipose tissue and adventitia, under con...

Background: It is unclear whether early physical activity has a greater influence on intima-media thickness and metabolic variables than current physical activity. Objective: To analyze the relationship between current and early physical activity, metabolic variables, and intima-media thickness measures in adults. Method: The sample was composed of 55 healthy subjects of both sexes (33 men and ...

BACKGROUND The prevalence of gallstone disease is increasing in Korea. Gallstone disease and atherosclerosis share common risk factors. Ultrasonographic carotid intima-media thickness is an independent predictor of atherosclerosis. We measured the carotid intima-media thickness among men who had gallstones to establish the association between atherosclerosis and gallstones. METHODS A total of...

This report is a concise review of current knowledge of the structure and function of the intima of the aorta and the major distributing arteries. The main purpose of the review is to delineate normal arterial intima from atherosclerotic lesions and, in particular, to distinguish physiological adaptations from atherosclerotic increases in intimal thickness. To characterize normal intima, includ...

To evaluate ultrasonographically determined intima-media thickness as a measure of early atherosclerosis, three studies were performed. Ultrasound measurements of intimamedia thickness in the carotid artery were directly validated by comparing the same thickness measured by light microscopy. The values were closely correlated (r=.82, P<.001). Intima-media thickness determined by light microscop...

Plasma clotting factor VII and plasma fibrinogen have been claimed as independent risk factors for occlusive cardiovascular disease. The aim of this study was to investigate whether these coagulation parameters affect early atherosclerosis, additional to their possible effect on arterial thrombosis. We used high-resolution quantitative ultrasonography to measure carotid intima-media thickness i...

While hypertension is known to cause left ventricular and vascular hypertrophy, the relationship between alterations of vascular and cardiac structures in patients with hypertrophic cardiomyopathy has not been fully clarified. We measured intima-media thickness of carotid arteries by ultrasonography in patients with hypertrophic cardiomyopathy (n = 16), normotensive subjects (n = 358), and hype...

To evaluate the association between common carotid intima-media thickness and noninvasively assessed atherosclerosis elsewhere in the carotid artery, we used data from the Rotterdam Study, a single-center population-based, prospective follow-up study among 7983 subjects aged 55 years or older. Baseline measurements included ultrasonographic evaluation of the vessel wall characteristics of the c...

For low density lipoprotein (LDL) particles to be atherogenic, increasing evidence indicates that their residence time in the arterial intima must be sufficient to allow their modification into forms capable of triggering extracellular and intracellular lipid accumulation. Recent reports have confirmed the longstanding hypothesis that the major determinant(s) of initial LDL retention in the pre...

Subarachnoid hemorrhage (SAH) resulting from a ruptured intracranial aneurysm can induce cerebral vasospasm with subsequent reduction in cerebral blood flow (CBF). The present study examines the pathological alterations in the wall of human cerebral arteries at autopsy, especially with regard to intimal pathology, following aneurysmal SAH. Arterial segments from the circle of Willis were fi...
