I'm a paramedic and have worked probably hundreds of cardiac arrests. I've gotten a pulse back on 5-10%. out of every 10 we get a pulse back, only 2-3 or so actually go home again neurologically intact. It all depends on how long they are down before cpr was started. I've had many patients that we got a pulse back on that were declared brain dead due to being down too long. 
Things look bad, but I wasn't involved and don't know details on her case, but odds are heavily against her.
People magazine is reporting that she has died. >

Just saw it on the news at the bar, reporting dead.  Sad how sometimes history repeats itself in odd ways >

I wouldn't call it "odd", considering heart issues can be genetic, she has a history of multiple drug abuse, has been dealing with grief for the past two years, and has shown signs of being physically weak in the last months.
I get what you're saying, but this doesn't come off like some horribly odd tragedy, it comes off like a horribly preventable tragedy. >

How does this come off as “preventable”? >

Drugs are bad mmmkay >

Priscilla has made a statement saying Lisa Marie passed. RIP. >

First her husband, grandson, and now her daughter. No one deserves to lose that many people in their life. >

If you live long enough, you're going to lose a lot of loved ones. Priscilla is 77.
