How does aspirin help during a heart attack?


Quick Answer

Aspirin helps to limit the clotting of platelets, which are the cells responsible for blocking arteries during a heart attack. If aspirin is not taken during a heart attack, arteries will narrow down and platelets will clot, causing a blockage of the arteries, thereby effectively cutting off supply of oxygen-rich blood to the heart. Without oxygen in the blood, death is inevitable.

Full Answer

Aspirin helps in thinning blood, which is why it is useful during a heart attack. After a heart attack, aspirin can also help prevent a subsequent attack since it keeps blood from clotting within the arteries. It is encouraged that people at high risk of getting heart attacks should take low levels of aspirin on a daily basis, according to the American Heart Association.

People with aspirin allergies, who have had hemorrhagic stroke, are under medication, are vulnerable to gastrointestinal bleeding and those who frequently consume alcohol should only take aspirin under instructions of a professional doctor.

It is equally important to remember that taking aspirin should never be a substitute to seeking help in case of a heart attack.

Aspirin may also help people who have other conditions, including unstable angina, coronary heart disease, stroke and those who have undergone a bypass operation.
