Study: Marathons up risks, delay treatment for others
Marathons can be risky for hearts, but not necessarily those of the runners. It takes longer for nearby residents to get to a hospital for emergency heart care on the day of a race and they’re less likely to survive, a U.S. study finds.
For every 100 people suffering a heart attack or cardiac arrest, three to four more died within a month if they had sought care on a marathon day versus another time, the study found.
It was published Wednesday by the New England Journal of Medicine, just before Boston’s annual 26.2-mile (42-kilometer) race, set for Monday.
The study included marathons in Boston, Chicago, Honolulu, Houston, Los Angeles, Minneapolis, New York City, Orlando, Philadelphia, Seattle and Washington between 2002 and 2012. It did not include 2013, when bombs at the Boston Marathon might have caused unusual delays.
