Prevalence of disease of the large arteries in an elderly Belgian population: relationship with some metabolic factors.
We measured the ankle pressure ratio (IPs) with the Doppler in a series of 261 subjects, mean age 80.6 +/- 5.3 years. The values of IPs has been distributed in three groups: IPs less than 0.9 related to an obstructive peripheral arterial disease, 2 greater than IPs greater than 0.9 patient with normal arteries, and IPs greater than 2 which corresponds with an arterial incompressibility. The ratio (formula; see text) so called "atherogenic index" was calculated in the three groups and related to the IPs. Forty five percent of the subjects have an abnormal IPs; in 32% it was due to a peripheral obstructive arteriopathy and in 13% to an arterial incompressibility. After 80, this specific condition was found in 17% of the observed population, we therefore suggest that it could be a senescence phenomenon, independent of atherosclerosis. We did not observe significant differences between the atherogenic index following the peripheral arterial condition. We can consider that an abnormal lipidogram is no more a risk factor in this very old population.
