Effect of Multiple Prior Percutaneous Coronary Interventions on Outcomes After Coronary Artery Bypass Grafting.

Background: The effect of multiple prior percutaneous coronary interventions (PCIs) before subsequent coronary artery bypass grafting (CABG) on long-term outcomes has not been well elucidated.

Methods and results: Between 2007 and 2016, 1,154 patients undergoing primary isolated CABG in our institution had no prior PCI (Group N), 225 had a single prior PCI (Group S), and 272 had multiple prior PCIs (Group M). Cumulative incidences of all-cause death, cardiac death and myocardial infarction (MI) at 10 years post-CABG were highest in Group M.
