Toronto Physician Dr. Ken Walker (under the pen name name Gifford-Jones) recently wrote an article wherein research conducted by Myra Cocker of the Stephenson Cardiovascular MR centre at the Libin Cardiovascular Institute of Alberta was highlighted.

Myra Cocker, a researcher at the Stephenson Cardiovascular Centre in Calgary, has been using imaging techniques to study athlete’s hearts.
It was hoped she and her colleagues would discover why some athletes in superb condition suffer sudden cardiac arrest and die.
What they found was equally alarming.
Forty-eight Olympic calibre athletes with a mean age of 32 years were enlisted in the study.
They were involved in swimming, cross-country skiing, skating and marathon running. Contrast-enhanced cardiovascular magnetic resonance scans were then done on the athletes. In addition, the same study was carried out on eight others in good health, but who were not involved in a training schedule.
This study showed that 75 per cent of the elite athletes had myocardial fibrosis (scarring of the heart’s muscle). They also had large ventricles (chambers of the heart).
At the moment it’s not known what effect this finding will have on longevity. But they believe this scarring will prevent them from ever becoming world champions regardless of how hard they train. Just 13 per cent of the control group had this condition.
