OBJECTIVE Increased levels of C-peptide, a cleavage product of proinsulin, circulate in patients with insulin resistance and early type 2 diabetes, a high-risk population for the development of a diffuse and extensive pattern of arteriosclerosis. This study tested the hypothesis that C-peptide might participate in atherogenesis in these patients. METHOD(More)
Increased levels of C-peptide, a cleavage product of proinsulin, circulate in patients with insulin resistance and early type 2 diabetes mellitus. Recent data suggest a potential causal role of C-peptide in atherogenesis by promoting monocyte and T-lymphocyte recruitment into the vessel wall. The present study examined the effect of C-peptide on vascular(More)
BACKGROUND This study examined whether atherosclerosis in young people is associated with the risk factors for clinical coronary heart disease (CHD). Methods and Results-Histological sections of left anterior descending coronary arteries (LADs) from 760 autopsied 15- to 34-year-old victims of accidents, homicides, and suicides were graded according to the(More)
BACKGROUND Obesity is a risk factor for adult coronary heart disease and is increasing in prevalence among youths as well as adults. Results regarding the association of obesity with atherosclerosis are conflicting, particularly when analyses account for other risk factors. METHODS AND RESULTS The Pathobiological Determinants of Atherosclerosis in Youth(More)
This review assesses the current status of knowledge concerning the relationship of risk factors to atherosclerotic lesions. Risk factors for atherosclerotic lesions per se need not necessarily be identical to those related to clinically overt coronary heart disease (CHD). This review is based on 1) autopsy studies where information risk factors was(More)
In 1972-1973, about 16,200 men living in Oslo, aged 40 to 49 years, were examined for cardiovascular disease, and had a number of coronary risk factors measured. This report gives the results of 129 autopsied cases with regard to the association between raised atherosclerotic lesions in coronary and cerebral arteries and various coronary risk factors. For(More)
A multi-institutional study, Pathobiological Determinants of Atherosclerosis in Youth (PDAY), was initiated to document the natural history of atherosclerosis, its relationship to risk factors, and the pathobiology of lesion development in young subjects. Pathology laboratories in nine centers collected arteries and tissues from > 2000 persons, ages 15-34(More)
BACKGROUND The strong association between coronary heart disease and dyslipoproteinemia has often overshadowed the effects of the nonlipid risk factors-smoking, hypertension, obesity, and diabetes and impaired glucose tolerance-and even led to questioning the importance of these risk factors in the presence of a favorable lipoprotein profile. METHODS AND(More)
OBJECTIVE To determine the associations among serum C-reactive protein (CRP) concentration, age, sex, risk factors for coronary heart disease (CHD), and atherosclerosis in young people. METHODS AND RESULTS In 1244 subjects 15 to 34 years of age, we measured gross atherosclerotic lesions in the right coronary artery (RCA) and abdominal aorta (AA) and(More)
Atherosclerotic lesions were induced in rhesus monkeys by feeding them a high-fat, high-cholesterol diet for 2 years. Arteries were examined after autopsy of a subgroup of animals (group P) and cholesterol was removed from the diet of the remaining animals. Lesions were examined in other subgroups after 30 weeks (group R1) and after 52 weeks (group R2). A(More)
