Furthermore, there ill be interest in predicting outcomes in advance for each atient or for health care providers. Thus, multiple attempts ave been made to estimate risk based on observational utcome databases (1–8). A recent effort to develop models o predict risk of CABG and PCI has been made using the ew York State database (9,10). This database offers the istinct advantage of being complete for all patients underoing coronary revascularization in the state of New York.
