-Summary
The COBIS III registry is a multi-center, real-world registry of 2nd generation drug-eluting stenting in coronary bifurcation lesions in South Korea. From 21 major coronary intervention centers in Korea, a total of 3,000 patients (anticipated) will be enrolled in this database between January 2010 and December 2014.
The aim of the study was to investigate long-term clinical results and predictors of adverse outcomes after percutaneous coronary intervention with 2nd generation drug-eluting stents for coronary bifurcation lesions in South Korea.

+Outcome measures
Primary outcomes
- Target lesion failure [5 years]: composite of cardiac death, myocardial infarction, or target lesion revascularization
Secondary outcomes
- Cardiac death [5 years]: All deaths were considered cardiac cause unless obvious non-cardiac causes could be identified
- Myocardial infarction [5 years]: an elevation of creatine kinase-myocardial band or troponin level greater than the upper limit of normal with concomitant ischemic symptoms or electrocardiography findings indicative of ischemia
- Target lesion revascularization [3 years]: repeat PCI of the lesion within 5 mm of the inserted stent
- Stent thrombosis [5 years]: the Academic Research Consortium as definite, probable, or possible
