Deep vein thrombosis, according to my veterinary wife, can be caused by sludging of the blood (high hematocrit) which causes damage to the vein leading to leakage. I suppose the issue is whether or not the stress on deep veins from cycling years using EPO can result in vein damage that can lead to thrombosis problems a few years later. Furlan was a patient of Ferrari with Ferrari's records indicating that Furlan's hematocrit went from 38.8 to 51 during a period of six months. This sounds unlikely to me. I think if the blood is thick enough to cause "sludging" the effects would be immediate and grave. After discontinuing EPO, the crit probably would return to normal within a few months at most (IIRC, the average life of an erythrocyte is about 120 days). OTOH, I would guess that depending upon saddle style, posture, etc. that years of sitting in the saddle could affect venous return from the legs. Without getting into gruesome details, I've personally seen some unpleasant effects. Furthermore, perfectly healthy people can have problems with leg thromboses in certain circumstances, such as sitting relatively immobile on a long transatlantic flight. Thrombosis and emboli are becoming more recognized as a significant risk in situations like this. http://tinyurl.com/4l4qf Steve I happened across this when Googling deep vein thrombosis polycythemia.

IIRC, DVT and resultant PE kills more people than heart attacks and AIDS in the USA. http://tinyurl.com/4l4qf Steve I happened across this when Googling deep vein thrombosis polycythemia.

Maybe you should ask your vet. And ask if such damage is permanent or repairable over time as well. |

Do you have two wives, or is your wife an ophthalmological specializing vet? If she knew the answer to the first part of your question, why doesn't she know the second part or at least know where to find the answer? |

She couldn't be bothered checking. We have enough human doctors lurking around here that we should be able to get an answer, if there is one. I doubt there have been any clinical studies of retired cyclists who raced under EPO with hematocrits of 60%+. |
