(1) Patients with a history of hypersensitivity reactions to components of aspirin or to salicylic acids
(2) Patients with peptic ulcer
(3) Patients with a bleeding tendency
(4) Patients with aspirin-induced asthma (asthma attacks triggered by drugs such as NSAIDs) or a history of it
(5) Other patients in whom long-term DAPT with aspirin is medically not recommended according to an investigator (the reasons should be specified)
3. Patients who are planned to receive long-term prasugrel therapy (for at least 6 months)
4. Patients 20 years of age or older at the time of informed consent
5. Patients who provide written informed consent to their own participation in this study
