[BDSP. Notice produite par INIST-CNRS JLf9R0xI. Diffusion soumise à autorisation]. Background : This report presents population-based estimates of the prevalence of peripheral arterial disease (PAD), chronic critical limb ischemia (CLI), and Moenckeberg's medial calcinosis (MC) in Germany. Patients and methods : From the year 2000 to 2003, a total of 4,814 subjects aged 45-75 years were included in the study. In 30 of the subjects (0.6%), determination of the ankle brachial index (ABI) was not possible, leaving 4,735 subjects (99.4%) in the data set. PAD was considered present in all subjects with an ABI1.3, about 13.3% of males and 6.9% of females had MC. In contrast to PAD, the prevalence of MC did not increase with age. With the criterion of ABI>1.5, MC was present in only 1.1% and 0.5% of men and women, respectively, but only 30 (0.6%) subjects had incompressible ankle arteries with a cuff pressure>260 mmHg. Conclusion : Prevalences of PAD based only on ABI generally underestimate the true prevalence of PAD in population-based studies. CLI predominantly affects older subjects. In addition, cut-off values for MC must be newly determined.
