Study population: Patients with coronary bifurcation lesion treated with drug-eluting stents

Brief summary: The COBIS II registry is a multi-center, real-world registry of drug-eluting stenting in coronary bifurcation lesions in South Korea. From 18 major coronary intervention centers in Korea, a total of 2,873 patients were enrolled in this database between January 2003 and December 2009.

The aim of the study was to investigate long-term clinical results and predictors of adverse outcomes after percutaneous coronary intervention with drug-eluting stents for coronary bifurcation lesions in South Korea.

Exclusion Criteria:

* Protected left main disease previous CABG for LAD or LCX territory
* Cardiogenic Shock
