Association between ambient temperature and acute myocardial infarction hospitalisations in Gothenburg, Sweden: 1985-2010.

Cardiovascular disease (CVD) is the number one cause of death globally and evidence is steadily increasing on the role of non-traditional risk factors such as meteorology and air pollution. Nevertheless, many research gaps remain, such as the association between these non-traditional risk factors an...
