re: Concerning our friend Raoul
Thanks for the update, sounds positive.
When you say Raoul had "pericarde" does that translate into pericarditis (an inflammation of the membrane around the heart)? If so, that would explain someone as healthy-seeming as Raoul having a "heart attack" as pericarditis can strike without someone having the typical precursors of more common heart diseases. Ususally the prognosis is good - a friend had an attack of pericarditis when he was about 25, he is now over 50 and has had no further problems related to the episode.
In any case, please pass on best wishes - thanks, Ashraf!
