Heat waves and cardiovascular emergencies: a study focused on Milan
In 18 highly vulnerable districts of Milan, home to 23% of the city’s population, the risk of cardiovascular emergencies increases by 22% during days of extreme heat compared to normal days. In contrast, in 20 low vulnerability districts, the increased risk is not significant.
A new study conducted by D-Hygea Lab of the Department of Electronics, Information and Bioengineering of the Politecnico di Milano, in collaboration with the Regional Emergency Agency (AREU), has analysed the impact of heat waves on the cardiovascular health of Milan residents. Milan was divided into 86 districts and 11 features were considered.
A higher percentage of elderly and high educated residents is associated with increased cardiovascular risk. In contrast, the density of public fountains and a higher percentage of female residents are linked to a lower risk of emergencies during hot weather.
This study allows us to clearly visualize where and how extreme heat affects the cardiovascular health of residents. These data can guide targeted policies, such as increasing green areas in the most vulnerable districts.
