Popis: Objective : We tested the hypothesis that transendothelial exchange of low-density lipoprotein (LDL) is influenced by the presence of severe atherosclerosis; we previously found this exchange elevated in diabetes patients. Methods : By an in vivo isotope method, we compared transendothelial LDL exchange in 24 patients with angiographically verified coronary atherosclerosis, 11 patients with angiographically verified peripheral atherosclerosis, 60 patients with diabetes, and in 42 controls. Autologous 131-iodinated LDL (131I-LDL) and 125-iodinated albumin (125I-albumin) were injected intravenously (i.v.), and the 1-h fractional escape rates (FERLDL and FERalb) were taken as indices of transendothelial exchange. Results : Patients with coronary or peripheral atherosclerosis had FERLDL similar to that of controls [4.3 (3.5–5.1) and 3.2 (2.3–4.1) versus 4.2 (3.7–4.7)%/h; P >0.05], even after adjustment for LDL distribution volume (DVLDL). In contrast, diabetes patients had significantly higher FERLDL than controls [5.2 (4.6–5.7) versus 4.2 (3.7–4.7)%/h; P
