Evaluating Efficacy and Safety of Short Duration of DAPT After Genoss DES Stent Implantation in Patients

Study Overview
=================
Brief Summary
-----------------
The investigators aimed to evaluate the safety and effectiveness of short-term DAPT (3 months for SCAD, 6 months for ACS) after PCI with Genoss DES in patients with coronary artery disease.

Detailed Description
-----------------
This study is a sponsor-initiated clinical trial (SIT) that enrolls patients with coronary artery disease who have undergone percutaneous coronary intervention using the GENOSS DES stent as research subjects, collects data on the patients' clinical and surgical procedures, and reports on clinical events. The investigators will track the outbreak. This study is a prospective, multicenter registration observational study that will enroll patients with coronary artery disease who underwent percutaneous coronary intervention with GENOSS DES at a total of five institutions. This study is a registered observation study and does not separately calculate the number of subjects, but plans to recruit a total of 1,000 subjects during the study period.

Official Title
-----------------
Prospective Multicenter Observational Study for Evaluating Efficacy and Safety of Short Duration of Dual Antiplatelet Therapy After Genoss DES Sirolimus-eluting Stent Implantation in Patients With Coronary Artery Disease

Conditions
-----------------
Acute Coronary Syndrome, Percutaneous Coronary Intervention, Dual Antiplatelet Therapy

Intervention / Treatment
-----------------
* Device: Genoss DES stent


Participation Criteria
=================
Eligibility Criteria
-----------------
Inclusion Criteria: Adults aged 19 or older Subjects treated for coronary artery disease using the Genoss DES stent Subjects who agree to the research protocol and clinical follow-up plan, voluntarily decide to participate in this clinical study, and provide written consent in the research subject consent form. Exclusion Criteria: Psychogenic shock at the time of hospitalization Expecting to become pregnant, pregnant or lactating woman In cases where the remaining survival period is expected to be less than 1 year due to a concomitant medical disease Subjects participating in other medical device randomization studies Subjects who received treatment using a different DES or BMS at the time of registration (however, due to failure of Genoss DES stent insertion, insertion of other stents is allowed)

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| device-oriented composite end point | cardiac death, any myocardial infarction not clearly attributable to a nontarget vessel, clinically indicated target-lesion revascularization | 12 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| patient-oriented composite end point | all-cause mortality, any myocardial infarction, any revascularization All deaths at 12 months Psychogenic death at 12 months Non-cardiac death at 12 months All myocardial infarctions at 12 months All myocardial infarctions that are not clearly related to non-target vessels at 12 months All reperfusions at 12 months Reperfusion of clinically appropriate target lesions at 12 months Stent thrombosis by ARC definition at 12 months Lesion success during the procedure: When the final remaining lesion stenosis is less than 30% using any surgical method. Procedure success: When the final residual lesion stenosis is less than 30% using any surgical method, and there is no death, myocardial infarction, or reperfusion after the procedure during the hospitalization period. | 12 months |
