Impact of Environmental Exposure at Home Address on One-year Post-myocardial Infarction Survival (ENVI-MI)

ENVI-MI (Environment and Myocardial Infarction) : Impact of Environmental Exposure at Home Address on One-year Post-myocardial Infarction Survival

Numerous studies have explored the effects of environmental exposure to noise, air pollution and proximity to "natural" areas on various conditions. However, very few studies have focused on the "post-diagnosis" follow-up of patients after hospitalization for an ischemic cardiovascular episode and, to our knowledge, none have examined patient evolution at one year after myocardial infarction. Thus, the real influence of factors and pollutants widely represented in the urban environment, in particular air pollution, noise pollution, and proximity and accessibility to natural areas ("green" or "blue" spaces), on the evolution of post-myocardial infarction at one year remains to be identified and quantified.

The objective of the ENVI-MI project is to evaluate the impact of environmental exposure in the place of residence (noise, air pollution, proximity to "natural" spaces) on the evolution of post-myocardial infarction at one year within the Dijon metropolitan area.
