Cold weather exposure linked to increased risk of heart attacks

A nationwide study in Sweden reveals that short-term exposures to lower air temperature and cold spells are associated with an increased risk of myocardial infarction hospitalization after two-six days. Researchers found that this delay in hospitalizations suggests a delayed onset of cold-related impacts on MI risk.
