You have to pick:

Depends; do I survive this heart attack?

Will the killer robots do my bidding? Cause that may change my answer

I suspect the killer robots would AT BEST do your bidding as likely as a human army would. So the more rich, smart, and powerful you are, the more likely they'll be following your commands. On the other hand, maybe they just hate all humans (like the Matrix) or perhaps they aren't intelligent but just have a directive to kill all humans that can't be argued with.

In any case, they are PROBABLY not on your side. If you are the president or a genius scientist or an eccentric billionaire then MAYBE you have a chance if you're lucky.

You're as likely to survive as anyone is to survive a heart attack. The survival rate of a full on cardiac arrest is about 10%. That said angina is often called a mild heart attack, which I think should be included here. The survival rates on that are quite high (75-90% depending on the circumstances).

Both have long term consequences, if you do survive, of course. And even if you only have the mild, 90% survivable type, your chance of having the full 10% survivable type in the future is now much higher.
