[|Human|] I just saw a guy about 75 years old have a huge problem. I was at the food court of a shopping centre when I noticed this guy look up in his chair with his mouth open. I called the emergency number. he was unresponsive almost as soon as he sat down, as I was giving him some first aid (CPR) he vomited. so two questions. is the vomiting a sign that he will be alright and how long can it take for a severe heart attack to kill someone.
[|AI|]  Hello, Thanks for posting in Chat Doctor. Vomiting in supposedly just another symptom caused due to myocardial infarction as there are symptoms like chest pain and pain in left arm or sweating. The duration of death due to myocardial infarction depends on the severity of the damage done to the heart muscles. If there is lots of damage done, it will be instantaneous. But if a patient is taken to hospital and managed immediately and required treatment is provided in golden period of time, he can survive. So, if you gave CPR to him, and he has vomited and been taken to hospital immediately there are chances he might make through.
