Study shows increased risk of heart attack from physical exertion at altitude and low temperatures during winter sports vacations

ScienceDaily (2010-09-01) -- A study carried out by cardiologists has investigated the risk of myocardial infarction (heart attack) amongst winter sports tourists to the Tyrolean Alps. The research shows that inadequate preparation for the intense physical exertion required, combined with the effects of altitude and low temperature, leads to an increase in heart attack incidents, particularly during the first two days of vacation.
