why do you take aspirin during a heart attack


Aspirin works on platelets by stopping their clotting action. Since blood clots can block the arteries that supply blood to your heart, the anti-clotting action of aspirin means blood can flow more easily while you seek further medical help to take care of the blockage. Since maintaining blood flow is important, sometimes doctors recommend an aspirin regimen for heart attack survivors to help prevent another heart attack from happening. Aspirin is not appropriate for everyone, so be sure to talk to your doctor before you begin an aspirin regimen.

This buildup is called plaque. Plaque usually affects large and medium-sized arteries. Plaques can grow large enough to significantly reduce the blood\’s flow through an artery. But most of the damage occurs when a plaque becomes fragile and ruptures. Plaques that rupture cause blood clots to form that can block blood flow or break off and travel to another part of the body. This is called an embolism. If a blood clot blocks a blood vessel that feeds the heart, it causes a heart attack. If a blood clot blocks a blood vessel that feeds the brain, it causes a stroke.


Aspirin helps prevent blood clots from forming and helps prevent heart attack and stroke. Certain patients will be prescribed aspirin combined with another antiplatelet drug (such as clopidogrel, prasugrel or ticagrelor) also known as dual antiplatelet therapy (DAPT).
