It is just so casually putted that the level of seriousness associated with a heart attack makes it absurdly to be putted this way. Where I am from, in Romania, a heart attack is basically a death sentence. Regarding this, I have read an article recently[1] which stated that in Romania only 3% percent survive if they have a heart attack outside of a hospital.
