Aspirin’s Proven Benefit
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 . Then, a blood clot can quickly form and block the artery. This prevents blood flow to the heart and causes a heart attack. Aspirin therapy reduces the clumping action of platelets — .

If you have ever had a heart attack, your doctor has probably told you to carry an aspirin or two with you at all times and to chew and swallow one immediately if you ever think you might be having another heart attack.
As it turns out, in the very earliest stages of a heart attack, in those critical minutes when part of your heart muscle is losing its blood supply, a simple aspirin can make a huge difference.
Anyone who has had a heart attack in the past, or is known to be at risk for a heart attack in the future, should always carry a few aspirin with them, and chew and swallow one immediately if they experience significant chest pain or any other signs of an acute heart attack.
A heart attack, also called myocardial infarction , is usually a form of acute coronary syndrome ACS. ACS is triggered by the rupture of a plaque within a coronary artery. This plaque rupture causes a thrombus blood clot to form within the artery, leading to a blockage. The portion of the heart muscle being supplied by the artery then begins to die. The death of heart muscle is what defines a myocardial infarction. What this means is that, at the time you are having a heart attack, a big part of the problem is the growth of a blood clot within the affected artery.
Formation of this blood clot depends to a large extent on the blood platelets, which are tiny blood cells whose job is to participate in blood clotting. It turns out that aspirin—even in small doses—can rapidly and powerfully inhibit the activity of the platelets, and therefore can inhibit the growth of the blood clot.
Inhibiting the growth of the blood clot is critical if you're having a heart attack since maintaining at least some blood flow through the coronary artery can keep heart muscle cells from dying.
Just as importantly, clinical trials have also strongly suggested that the early administration of aspirin can substantially reduce the size of the myocardial infarction, or convert a heart attack to unstable angina , or convert an ST-segment elevation myocardial infarction STEMI to a non-ST segment elevation myocardial infarction NSTEMI. This is why chewing and swallowing an aspirin is usually one of the first things you will be asked to do when you arrive in the emergency room with a suspected MI — if you have not done so already.
But time is of the essence—minutes count. So if you think you might be having a heart attack, most experts now advise patients not to wait until they get medical help—chew and swallow an aspirin as soon as you are concerned enough to call the paramedics. By doing this you can begin treating the heart attack immediately, even before the paramedics arrive. The current recommendation for people who may be having a heart attack is to chew and swallow one non-coated adult aspirin mg as soon as possible.
Swallowing a whole aspirin with water, as you normally would, takes 10 to 12 minutes to achieve the same effect. This time difference may seem small, but, once again, minutes count when your heart is at risk.
