详细描述
The goal of this observational study is to evaluate the association between Murray law-based quantitative flow reserve and outcomes after coronary artery bypass graft surgery. By constructing registry database during 10-year periods, several types of study objectives including 'graft patency' and 'long-term clinical outcomes' will be evaluated.
