  Description
Prasugrel: <75 Years of Age

Prasugrel and Low-dose Commercially-available Aspirin in participants less than (<) 75 years of age.

Commercially-available Aspirin: Low-dose aspirin, oral, as prescribed by physician through end of study.

Prasugrel: 30 milligram (mg), oral, once as loading dose (in those subjects who initiate study drug with a loading dose); and either 5 mg or 10 mg (based upon weight) orally, once daily as maintenance dose through end of study.

Prasugrel: 75 Years of Age or Older

Prasugrel and Low-dose Commercially-available Aspirin in participants 75 years of age or older.

Commercially-available Aspirin: Low-dose aspirin, oral, as prescribed by physician through end of study.

Prasugrel: 30 milligram (mg), oral, once as loading dose (in those subjects who initiate study drug with a loading dose); and 5 mg orally, once daily as maintenance dose through end of study.

Clopidogrel: <75 Years of Age

Clopidogrel and Low-Dose Commercially-available Aspirin in participants less than (<) 75 years of age.

Commercially-available Aspirin : Low-dose aspirin, oral, as prescribed by physician through end of study

Clopidogrel: 300 milligram (mg), oral, once as loading dose (in those subjects who initiate study drug with a loading dose); and 75 mg, oral, once daily as maintenance dose through end of study

Clopidogrel: 75 Years of Age or Older

Clopidogrel and Low-Dose Commercially-available Aspirin in participants 75 years of age or older.

Commercially-available Aspirin: Low-dose aspirin, oral, as prescribed by physician through end of study.

Clopidogrel: 300 milligram (mg), oral, once as loading dose (in those subjects who initiate study drug with a loading dose); and 75 mg, oral, once daily as maintenance dose through end of study.
