Overview: Japanese guidelines for myocardial revascularization to treat stable ischemic heart disease 2012.

Since its introduction in the early 1970s, coronary artery bypass grafting (CABG) has become an established surgical treatment for coronary artery disease (CAD). Percutaneous coronary intervention (PCI), first clinically applied in 1977, was promoted as an alternative to CABG during the mid-1980s. Along with the nationwide expansion of PCI, the ratio of PCI to CABG has exceeded 6-7:1. The Japanese Circulation Society (JCS) published "Guidelines on elective coronary intervention, including coronary artery bypass grafting (CABG), for ischemic heart disease in 2000" and "Guidelines on the selection of bypass conduits and operative procedures in coronary artery bypass grafting for ischemic heart disease". The society intended to revise these guidelines in 2010 and to issue two new guidelines specific either to PCI or CABG. They also planned to issue joint guidelines for myocardial revascularization and PCI/CABG, which are primary indications for patients with stable CAD, especially with those with more complex left main trunk disease and/or multi-vessel disease. The scientific committee of JCS established the "Council for myocardial revascularization" that consisted of experts including interventional and non-interventional cardiologists, cardiac surgeons and physicians specialized in diabetes or nephrology selected by medical and surgical societies. After over 10 rounds of meetings, the Council prepared primary guidelines for myocardial revascularization to treat stable CAD, PCI/CABG. These guidelines consist of (1) Statements about myocardial revascularization, (2) Interpretation of the statements and (3) Indications for PCI/CABG including a table.
