Coronary Artery Disease
Impact of Ticagrelor Re-load on Pharmacodynamic Profiles
Platelets are parts of your blood that stick together to help form a clot. The stickier your platelets are, the greater your chance of having a heart attack. A clot in the wrong place can lead to a heart attack or stroke.
