BACKGROUND A unique semiautomated border detection program (BDP) designed for use on a personal computer was evaluated to determine whether: (1) carotid intima-media thickness (CIMT) measurements were bioequivalent to a reference laboratory; and (2) it would allow a novice (NOV) reader with no medical training to accurately and reproducibly measure CIMT. METHODS Far-wall CIMT was measured bli...
The established method of polarized microscopy in combination with a universal stage is used to determine the layer-specific distributed collagen fibre orientations in 11 human non-atherosclerotic thoracic and abdominal aortas and common iliac arteries (63 ± 15.3 years, mean ± s.d.). A dispersion model is used to quantify over 37 000 recorded fibre angles from tissue samples. The study resulted...
BACKGROUND AND PURPOSE The purpose of this study was to assess the association of vitamin D deficiency and indices of mineral metabolism with subclinical carotid markers that predict cardiovascular events. METHODS Two hundred three community-dwelling adults (Northern Manhattan Study; age, 68 ± 11; age range, 50 to 93 years) had serum measurements (calcium, phosphorus, 25-hydroxyvitamin D, 1,2...
BACKGROUND AND PURPOSE Recent studies reported the differential effect of docosahexaenoic (DHA) and eicosapentaenoic acids (EPA). We examined the differential association of DHA and EPA with carotid intima-media thickness (IMT) in Japanese individuals in Japan and in U.S. white individuals and explored whether DHA or EPA contributes to the difference in IMT between the two groups. METHODS A p...
The vascular effects of normal pregnancy were investigated by estimating the intima and media thicknesses of the common carotid artery separately using 22-MHz ultrasound (Collagenoson, Meudt, Germany) in 57 healthy women with normal pregnancies and pregnancy outcomes, in all three trimesters and at 1 yr postpartum. A thick intima, thin media, and high intima-to-media (I/M) ratio are signs of a ...
Carotid intima-media thickness (CIMT) is a simple and inexpensive tool to assess the cumulative effect of atherosclerotic risk factors and is an independent predictor of future cardiovascular risk. CIMT is commonly used as a surrogate end point in research trials as a marker of atherosclerosis. However, new software programs have made CIMT a clinically practical examination for risk evaluation....
OBJECTIVE We examined the Type A behavior across developmental periods as a predictor of adult carotid artery intima-media thickness (IMT). METHODS AND RESULTS In this prospective cohort study of 408 men and 606 women, socioeconomic background and biological risk factors of participants were assessed at baseline at age 6 to 18 years of age, Type A behavior (Hunter-Wolf A-B Rating Scale) at th...
Increased intima-media thickness of the common carotid artery predicts increased risk of myocardial infarction and stroke. Preliminary evidence suggests that a decrease in blood pressure (BP) is associated with diminished wall thickness. It is not known if all classes of anti-hypertensive agents have similar protective effects. In this double-blind parallel-group clinical trial, 69 previously u...
BACKGROUND The present study was designed to characterize early structural changes of large arteries in renal transplant recipients with no clinical evidence of cardiovascular disease and normal blood pressure values, and to analyse the relationship between arterial alterations and those of the heart. METHODS Intima media thickness and atherosclerotic plaques of the carotid arteries as well a...
