A possible result could be catastrophic

I was talking to a doctor yesterday about Pericarditis and he said that one possible result could be catastrophic. I was well aware of that possibility, but I thought it was an unusual word for a doctor to use.

That being said, it does sound more powerful than you could die. A lot of people say, “You could die doing <fill in the blank>,” so maybe that phrase has lost some power, where “catastrophic” isn’t used that often to talk about one’s health.
