The social and economic environment has become a major determinant of cardiovascular health. The objective of our study was to assess socio-economic insecurity in patients with symptomatic PAD. The PRECAR study was a non-interventional prospective cohort study. Patients were recruited from the Vascular Medicine and Surgery Departments of Grenoble-Alpes University Hospital or during a consultation as part of the therapeutic education program "On the move! Better understanding and better living with arterial disease". The analysis of socio-economic and environmental data was based on the EPICES score (a reliable index used to measure individual deprivation) and INSEE parameters (level of education and socio-professional category). Cardiovascular risk factors were also recorded. 150 patients with symptomatic PAD were included between November 2017 and June 2018. 84% were men. In our population 54% (CI95% 45.7 - 62.1) were in a precarious situation compared to 40% (CI95% 39.8 - 40.2) in the general population, according to the EPICES score (P<0.001). Levels of education were low and patients with a baccalaureate or higher education degree were under-represented. Executives, intellectuals and intermediate professions were also under-represented in the PAD population. This data opens new perspectives on the social characterisation of patients that may contribute to improving the outcomes of patients with peripheral vascular disease., (Copyright © 2021.
