OMG, that's horrible. Him being a smoker would make him an obvious candidate for an MI, I'd think.
He had always smoked, so the doc treated him for emphysema, while the nurse thought something was going on with his heart.
The doc wouldn't listen to the nurse. My Gpa died on the bathroom floor of the hospital.
Turns out he had a congenital defect in his heart that could have been fixed if they had found it.
