Abstract
In a medical service for ambulant patients, 180 unselected octo‐ and nonagenarians were studied. They showed high‐density lipoprotein (HDL) values similar to those reported for younger age groups. In 81 patients, a combination of various noninvasive angiologic techniques was used in addition to the history and physical examination. The frequencies of the clinical signs of peripheral arterial disease, and of stenoses and occlusions in the lower‐limb vessels, differed significantly between three HDL‐cholesterol subgroups, being highest in the group with the lowest HDL values.
