Phidippides cardiomyopathy: Difference between revisions
Started the article, added some references - will need a lot of help sprucing this up. Saw that this condition have been shared around on social media but no wikipedia page to help balance expert opinion. |

Phidippides cardiomyopathy refers to the cardiomyopathic changes that occurs after long periods of endurance training. It was named after Phidippides, the famous Greek runner who died after running from Marathon to Athens in 490BC.
It was most notably coined by Dr James O’Keefe, director of the Preventive Cardiology Fellowship Program at Missouri’s Saint Luke’s Mid America Heart Institute, during a presentation at the annual meeting of the American College of Sports Medicine in June 2012[1]. He was speaking about the sudden death of Micah True, a 58-year-old ultrarunner and cult hero a.k.a. Caballo Blanco who died on a 12-mile training jog in the rugged Gila Wilderness of southwest New Mexico. After an autopsy, the Albuquerque coroner wrote that “Micah True died as a result of cardiomyopathy during exertion”. Since then, multiple websites have warned their readers on the possible damage from prolonged endurance training[2].
The suggested etiology for Phidippides Cardiomyopathy is the cardiac remodelling from prolonged strenuous exercises[3][4].
The repeated prolonged states of volume overload in the Right Atrium and Right Ventricle from endurance training will lead to chronic structural changes. Long term changes include patches of cardiac fibrosis which can allow zones of re-entry for cardiac arrhythmias[5].
It is suggested that Cardiac MRI is the best imaging modality[6] to investigate this condition.
Controversy
There is not much evidence describing this condition and other than a case report[7], no other studies have corroborated the pathophysiological changes suggested by Dr O'Keefe.
Not all experts agree with Dr O'Keefe and that further research is necessary to understand this condition better.
