(European Society of Cardiology) Cold weather is associated with a higher risk of severe heart attack, according to research presented at ESC Congress today by Dr. Shuangbo Liu, adult cardiology resident at the University of Manitoba in Winnipeg, Canada. The six-year study found that each 10°C drop in temperature was associated with a 7 percent increased risk of ST-elevation myocardial infarction, the most severe form of heart attack.
