・To evaluate the efficacy and safety of prasugrel monotherapy using computed tomography-derived fractional flow reserve (CT-FFR) after undergoing PCI with DES in patients for whom long-term DAPT with aspirin is not recommended.
・To evaluate the background factors of patients in whom long-term DAPT with aspirin is not recommended.
Safety,Efficacy
・Efficacy endpoints:
-Changes in CT-FFR values before and 6 months after switching monotherapy
-Cardiovascular events
・Safety endpoints:
-Bleeding events (BARC bleeding type 2, 3, or 5)
-All adverse events
・Baseline characteristics

Male and Female
Patients are included in this study if all of the following criteria are met:
1.Patients undergoing PCI with implantation of DES
2. Patients who are not planned to receive DAPT more than 3 months after PCI with DES, and who are not medically preferable to administrate Aspirin concomitantly for long-term. (those corresponding to at least one of the following items)
(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
Patients are excluded from the study if they meet any one of the following exclusion criteria.
1. Patients who will require DAPT for at least 3 months after DES implantation judged by an investigator (Examples are listed below.)
Patients with the following complex lesions
(1) Triple-vessel lesions
(2) Implantation of multiple stents (>= 3 stents)
(3) A history of treatment of at least 3 lesions
(4) Implantation of 2 stents in the bifurcation
(5) Total stent length of > 60 mm
(6) Chronic total occlusions
(7) Coronary artery stents in the left main trunk
2. Patients who are treated with or planned to be treated with ticlopidine, clopidogrel, and/or cilostazol
3. Patients with bleeding risk (Hemophilia, intracranial hemorrhage, gastrointestinal hemorrhage, urinary tract hemorrhage, hemoptysis, vitreous hemorrhage, etc.)
4. Patients with a history of hypersensitivity reactions to prasugrel
5. Patients who participate or will participate in a clinical trial or clinical research involving intervention before the end of follow-up in the study
