Your ex needs to go the the hospital NOW. If there's any aspirin
in the house give him some on the way. A heart attack
is when blood vessels supplying part of the heart muscle get blocked/narrowed leading eventually to death of the heart muscle and nerves. The longer he waits, the worse the outcome. There is just absolutely no justification to take the risk. It sounds like a heart attack to me.... if I'm wrong then great, but really, MUCH better to be safe than sorry. Seriously, men can be so stubborn.
