Explanation: 

Detailed explanation-1: -How can aspirin prevent a heart attack or stroke? Aspirin slows the blood’s clotting action by reducing the clumping of platelets. Platelets are cells that clump together and help to form blood clots. Aspirin keeps platelets from clumping together, thus helping to prevent or reduce blood clots.

Detailed explanation-2: -A review of the data for 135, 640 patients who had a first heart attack or stroke showed an 18 to 30 percent reduction in risk of a second event with aspirin doses of 75 to 150 milligrams daily.

Detailed explanation-3: -Historically, doctors recommended aspirin to high-risk patients as a harmless way to keep heart disease at bay. And for good reason – studies have shown that aspirin can reduce inflammation, prevents blood clots and lowers the risk of death among people suffering from a heart attack.
