Key result
An analysis of 10.9 million marathon runners demonstrated no significantly increased overall risk of cardiac arrest during long-distance races, despite transient exercise-induced cardiac alterations.
Why the study?
Does intensive endurance exercise like marathon running increase cardiovascular risk in middle-aged amateur athletes?

Marathon participation may carry cardiovascular risks for middle-aged amateurs; leaves open need for targeted risk stratification in observational data.
Does intensive endurance exercise like marathon running increase cardiovascular risk in middle-aged amateur athletes?
While marathon running causes transient cardiac strain and increases atrial fibrillation risk in middle-aged men, it does not significantly increase the overall risk of cardiac arrest.
Hans‐Georg Predel (2014) conducted a review in Cardiovascular risk. Marathon running was evaluated. An analysis of 10.9 million marathon runners demonstrated no significantly increased overall risk of cardiac arrest during long-distance races, despite transient exercise-induced cardiac alterations.
