However, there was no statistical difference in mortality or need for other treatments Treatment for intermediate risk PE patient remains controversial The same study will have second follow-up at 90 days to see if there are other benefits References Lookstein RA, Konstantinides SV, Weinberg I, Dohad SY, Rosol Z, Kope\u0107 G, Moriarty JM, Parikh SA, Holden A, Channick RN, McDonald B, Nagarsheth KH, Yamada K, Rosovsky RP; STORM-PE Trial Investigators.
