Study: High Temperatures and Hospitalizations for Cardiovascular and Respiratory Causes

In a study published in the March 1st edition of the American Journal of Respiratory and Critical Care Medicine, researchers evaluated the impact of high environmental temperatures on hospital admissions during April to September in 12 European cities. For each city, analysis was used to model the relationship between maximum temperature and daily hospital admissions for cardiovascular, cerebrovascular, and respiratory causes by age. The results showed that high temperatures have a specific impact on respiratory admissions, particularly in the elderly population, but the underlying mechanisms are poorly understood. The authors concluded that the impact of extreme heat events on respiratory admissions is expected to increase in European cities as a result of global warming and progressive population aging.
