Five years ago, my father had a massive heart attack. Thankfully, he was rushed to the emergency room and straight into the intensive care unit (ICU). His condition was so bad that he was on more nitroglycerin than his nurse had ever seen and he had to wait in ICU for nearly a week while he stabilized enough for the doctors to perform a quintuple bypass. (Yeah, that says quintuple; they bypassed all of the arteries in his heart). Spoiler alert: he survived. But, what if something had gone wrong while he was on the operating table?
