Lower extremities arterial disease (LEAD) is the third most common manifestation of atherosclerosis. The number of cardiovascular events in this population is similar to that of coronary artery disease. Management consists mainly of strict control of cardiovascular risk factors, optimal pharmacological treatment and supervised exercise training. Supervised exercise training is superior to other exercise modalities in terms of increased walking time, maximum walking distance, pain-free walking distance and quality of life scores. In association with revascularization, the benefits are enhanced. In Switzerland, federal programs have been created on this basis and exist in many cities. They are little known and yet essential.
