I think you and dewophile are using the word systemic differently than I am. Yes, leg compression has some beneficial effect all over the body. But would leg compression be considered a valid means of preventing a clot in, say, the coronary arteries following a stent procedure?
my recollection is that the primary MOA of leg compression is NOT mechanical but rather due to release of some endogenous anticoagulants - so i do mean a systemic effect in the true sense. i'm sorry i have no references or can't be more specific. regardless from an investing standpoing i think it is moot - i was raising it for purely academic reasons. i don't see mechanical compression displacing lovenox at all in the foreseeable future
