The info about temporary cardiac muscle enzyme elevation after endurance events is not new. However, I believe that the “conclusions” by the author, and as reported in this article in the last 2 paragraphs are irresponsible.
Certainly the hypothesis that temporary enzyme release represents muscle damage that could result in scarring is one that should be investigated. But to suggest in a paper, and have it picked up in the press and exposed ot the general public that endurance athletes are dying due to arrhythmias produced by scar tissue as a result of exercising over 3 hours a week is bad science and bad journalism.
Without electrophysiologic or autoposy data about the causes of death, these are just speculations and it’s far more likely they die from the much more common coronary artery disease.
