Patent Claims:	1. A method for reducing the rate of a composite endpoint of cardiovascular death, myocardial infarction, or stroke in a patient in recognized need thereof, comprising administering to the patient twice daily a pharmaceutical composition comprising 60 mg ticagrelor and a pharmaceutically acceptable carrier; wherein the patient has a history of myocardial infarction; wherein the patient is also administered a daily maintenance dose of aspirin of 75 mg to 150 mg; and wherein the rate of the composite endpoint in the patient is reduced relative to a dosing regimen where the patient receives the daily maintenance dose of aspirin of 75 mg to 150 mg only. 2. The method of claim 1, wherein the daily maintenance dose of aspirin is 75 mg to 100 mg. 3. The method of claim 1, wherein the patient has a history of myocardial infarction at least 12 months prior to the twice daily administration of the pharmaceutical composition comprising 60 mg ticagrelor and a pharmaceutically acceptable carrier. 4. The method of claim 1, wherein the patient has a history of myocardial infarction 12 to 36 months prior to the twice daily administration of the pharmaceutical composition comprising 60 mg ticagrelor and a pharmaceutically acceptable carrier. 5. The method of claim 1, wherein the patient has a history of myocardial infarction as a result of an acute coronary syndrome. 6. The method of claim 5, wherein prior to the administration, the patient was administered twice daily a pharmaceutical composition comprising 90 mg ticagrelor and a pharmaceutically acceptable carrier for a portion of 12 months after the acute coronary syndrome. 7. The method of claim 5, wherein prior to the administration, the patient was administered twice daily a pharmaceutical composition comprising 90 mg ticagrelor and a pharmaceutically acceptable carrier for 12 months after the acute coronary syndrome. 8. The method of claim 6, wherein the patient was administered a pharmaceutical composition comprising a 180 mg ticagrelor loading dose prior to administration twice daily of a pharmaceutical composition comprising 90 mg ticagrelor and a pharmaceutically acceptable carrier for a portion of the 12 months after the acute coronary syndrome. 9. The method of claim 1, wherein the method satisfies at least one of the following conditions: (a) the method numerically reduces the absolute risk of the composite endpoint of cardiovascular death, myocardial infarction, or stroke relative to a dosing regimen where the patient receives the daily maintenance dose of aspirin of 75 mg to 150 mg only; (b) the method results in a relative risk of the composite endpoint of cardiovascular death, myocardial infarction, or stroke of less than one relative to a dosing regimen where the patient receives the daily maintenance dose of aspirin of 75 mg to 150 mg only; (c) the method numerically reduces the Kaplan-Meier rate for the composite endpoint of cardiovascular death, myocardial infarction, or stroke compared to a dosing regimen where the patient receives the daily maintenance dose of aspirin of 75 mg to 150 mg only; (d) the method results in a statistically significant reduction in the rate of the composite endpoint of cardiovascular death, myocardial infarction, or stroke relative to a dosing regimen where the patient receives the daily maintenance dose of aspirin of 75 mg to 150 mg only; (e) the method results in a relative risk of the composite endpoint of cardiovascular death, myocardial infarction, or stroke that is statistically significantly less than one relative to a dosing regimen where the patient receives the daily maintenance dose of aspirin of 75 mg to 150 mg only; (f) the method results in a Kaplan-Meier rate for the composite endpoint of cardiovascular death, myocardial infarction, or stroke at three years of approximately 7.8%; (g) the method results in a hazard ratio for time to first composite endpoint of cardiovascular death, myocardial infarction, or stroke of less than one relative to a dosing regimen where the patient receives the daily maintenance dose of aspirin of 75 mg to 150 mg only; (h) the method results in a numerical reduction in the percentage of patients with composite endpoint events of cardiovascular death, myocardial infarction, or stroke relative to a dosing regimen where the patient receives the daily maintenance dose of aspirin of 75 mg to 150 mg only; (i) the method results in a hazard ratio for time to first composite endpoint of cardiovascular death, myocardial infarction, or stroke that is statistically significantly less than one relative to a dosing regimen where the patient receives the daily maintenance dose of aspirin of 75 mg to 150 mg only; (j) the method results in a hazard ratio for time to first composite endpoint of cardiovascular death, myocardial infarction, or stroke at three years of approximately 0.84 relative to a dosing regimen where the patient receives the daily maintenance dose of aspirin of 75 mg to 150 mg only; (k) the method results in a hazard ratio for time to first composite endpoint of cardiovascular death, myocardial infarction, or stroke at three years of 0.74 to 0.95 relative to a dosing regimen where the patient receives the daily maintenance dose of aspirin of 75 mg to 150 mg only; (l) the method results in a 95% confidence interval for the hazard ratio for time to first composite endpoint of cardiovascular death, myocardial infarction, or stroke at three years of 0.74 to 0.95 relative to a dosing regimen where the patient receives the daily maintenance dose of aspirin of 75 mg to 150 mg only; (m) the method reduces the absolute risk of the composite endpoint of cardiovascular death, myocardial infarction, or stroke at three years by approximately 1.27% relative to a dosing regimen where the patient receives the daily maintenance dose of aspirin of 75 mg to 150 mg only; (n) the method results in a relative risk reduction of approximately 17% for the composite endpoint of cardiovascular death, myocardial infarction, or stroke at three years relative to a dosing regimen where the patient receives the daily maintenance dose of aspirin of 75 mg to 150 mg only; (o) the method reduces the Kaplan-Meier rate for the composite endpoint of cardiovascular death, myocardial infarction, or stroke at three years by approximately 1.2% compared to a dosing regimen where the patient receives the daily maintenance dose of aspirin of 75 mg to 150 mg only; (p) the method reduces the percentage of patients with composite endpoint events of cardiovascular death, myocardial infarction, or stroke at three years by approximately 1.3% relative to a dosing regimen where the patient receives the daily maintenance dose of aspirin of 75 mg to 150 mg only; (q) the method results in a numerical reduction in the rare of the cardiovascular death relative to a dosing regimen where the patient receives the daily maintenance dose of aspirin of 75 mg to 150 mg only; or (r) the method results in a numerical reduction in the rate of the all-cause mortality relative to a dosing regimen where the patient receives the daily maintenance dose of aspirin of 75 mg to 150 mg only. 10.
