Reporting Groups

	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.
