People whose hearts stop functioning during or shortly after exercising are three times more likely to survive than those who have cardiac arrest unrelated to working out, researchers said.
The Amsterdam Resuscitation Study looked at 2,517 cardiac arrest cases in the Dutch capital’s greater metropolitan area over a three-year period. Scientists found 145 of the patients were exercising during or within one hour of cardiac arrest and were mostly biking, playing tennis, working out at a gym or swimming, according to the research presented today at the European Society of Cardiology conference in Munich.
Almost half of the patients who were exercising survived the event and they had a much better prognosis than those who weren’t working out, the study said. Only 15 percent of those whose cardiac arrest wasn’t exercise-related lived, the study said. Those who were exercising were mostly young and male and suffered cardiac arrest in a public place where they were more likely to receive cardiopulmonary resuscitation, or CPR, from a bystander, according to the researchers.
“The remarkably good survival of victims of exercise-Srelated out-of-hospital cardiac arrest can partially be ascribed to the fact that they are younger and more likely to suffer the arrest in a public location, leading to bystander CPR,” Arend Mosterd, a cardiologist at the Meander Medical Center in Amersfoot, the Netherlands, and a co-author of the study, said in a statement today. “Taking these factors into account, exercise per se also contributes to a better outcome.”
