What percent of AMI patients are treated with aspirin?

AMI = Acute Myocardial Infarction
Patients can have taken on own or administered by a qualified facility.

I don't know the exact percentage of patients who are given aspirin but every patient I've seen is treated with it. I've worked in a cardiac hospital and I did a rotation in the ER where I've seen many people with acute MI's. Aspirin was always given right away in the ER, and once the patient is moved on the floor they get placed on permanent aspirin therapy. They will receive other medications as well, like Lopressor and Heparin. I would recommend anyone who suspects they are having a heart attack to call for emergency services right away as well as taking an aspirin.

it is recommended that all, 100%, be treated with aspirin with symptoms of AMI....the person could chew one adult aspirin before arriving at facility.....but do not take aspirin instead of seeking medical care or begin long term aspirin therapy without consulting your MD first....

ASA is part of the standard for suspected AMI. The only contraindication I know is an aspirin allergy.
A lot of people take one these days before they go to the hospital with chest pain because of the education on tv.

In the ER the percentage is basically 100% unless the patient has a known allergy to aspirin....it is the medical protocols for an MI....and in the land of 911(depending on jurisdiction) it is given if an MI is suspected and not showing on the 12 lead EKG yet....
