Clinical trials

The objective of this study is to evaluate effectiveness and safety of the new drug-eluting stent (DES), as compared with the first-,second-,third-, and fourth-generation DES, in the "real world" daily practice.

The goal of this clinical trial is to compare long term efficacy of drug-eluting stent implantation compare to optimal medical treatment in patient with chronic total occlusion in a very long-term follow-up (minimum 10 years) period.

The objective of this study is to evaluate the effectiveness and safety of Coroflex ISAR NEO stents in comparison to other drug-eluting stents (DES) in real-world practice.

The primary purpose of the study was to determine whether the 2-year probability of major adverse cardiac events (primary composite outcome) differed significantly between patients who underwent angiography-guided Percutaneous Coronary Intervention(PCI) and those who underwent Fractional Flow Reserve(FFR)-guided PCI in patients with Left Main Coronary Artery disease(LMCA).

This study evaluates effectiveness and safety of DESyne X2 in Routine Clinical Practice.

The PREVENT-2 trial is to determine whether an initial invasive strategy-consisting of early coronary angiography (CAG) with intent for preventive percutaneous coronary intervention (PCI) in addition to optimal medical therapy (OMT)-reduces the incidence of the primary composite outcome of cardiac death, target-vessel myocardial infarction (MI), unplanned urgent revascularization, or hospitalization for unstable or progressive angina at 3 years, compared with an initial conservative strategy of optimal medical therapy (OMT) alone, in patients with high-risk vulnerable plaque identified by coronary computed tomography angiography (CCTA).

About 20,000 patients with FFR (Fractional Flow Reserve) will be enrolled and evaluated for the natural history of coronary lesions at 2 years clinical and imaging follow-up.

The purpose of this study is to observe clinical courses for long-term in patients with unprotected LMCA disease and to evaluate comparative results of medical treatment, coronary stenting with drug-eluting stents, and CABG for the treatment of an unprotected LMCA stenosis in the "real world" daily practice.

The objective of this study is to evaluate the effectiveness and safety of XIENCE Skypoint stents in comparison to other drug-eluting stents (DES) in real-world practice.

This study evaluates the effectiveness and safety rotational atherectomy in routine clinical practice.

This study evaluates long-term outcome of patients diagnosed as acute myocardial infarction and treated with medication, coronary artery bypass surgery and percutaneous coronary intervention in Asan medical center, Korea.

The purpose of this study is to evaluate the prognosis of coronary stenosis based on intracoronary Imaging.

The purpose of this study is to evaluate long-term prognoses of patients with multivessel coronary disease treated medically or surgically or percutaneously in real world practice.

The objective of this study is to evaluate effectiveness and safety of drug-eluting stent implantation in the "real world" daily practice.

The purpose of this study is to evaluate long-term effectiveness and safety of patients with coronary disease treated with drug eluting balloon in real world practice.
