Screening study of abdominal aortic aneurysm in a general population: lipid parameters

Abstract The level of blood lipids and apolipoproteins in subjects being screened for abdominal aortic aneurysms have been investigated. As part of an ultrasound screening programme in a population of 65- to 75-year-olds, blood samples were collected from 1460 of 1504 subjects with a normal aorta (97.1%) and 69 of 70 patients with an abdominal aortic aneurysm >29 mm (99%). Samples were also taken from 22 of 27 patients (81%) with an ectatic aorta (26–29 mm). Total cholesterol, HDL-cholesterol, LDL-cholesterol, Apo-AI and Apo-B levels were significantly higher in women than in men ( P P
