Hi,
Thanks for posting your query.
Did your friend has chest pain/ squeezing sensation in chest at the time of admission?
Did your friend has any other associated symptoms?
Did your friend has involvement of any other organ at the time of admission?
What was the age of your friend?
After reading your query, vomiting appears to be primary symptoms and heart attack appeared after continuous bloody vomit.
Recurrent and persistent vomiting may compromise blood circulation and may decrease blood supply to heart and may cause heart attack changes in ECG.
In heart attack, vomiting may occur but blood vomit is less common.
Take care,
Dr. Mayank Bhargava

Hi

Thanks for your query.

This is really shocking news. See vomiting foul smelling dark blood may be due to various reasons the most common is peptic ulcer disease and gastro-esophageal varix rupture. As this is huge bleeding varices have the more chance to occur. I think this huge bleeding caused shock to your friend that caused her death. Yes definitely there were scope of treatment in the form of pantoprazole, octreotide, fluid infusion, blood transfusion. Even if the bleeding is not controlled with this medical treatment then there was scope of surgery in the form of band ligation or balloon tamponade.

But facility of surgical option is not available in every hospital. But in that case they would have informed you. I think this far i can answer to your question.
Thank you.
