Repeat coronary artery bypass graft surgery (CABG)

When a coronary artery bypass grafting (CABG) patient needs a second surgery because of recurrent chest pain, more often than not it’s a percutaneous coronary intervention (PCI), commonly known as coronary angioplasty with stents.


A cohort study, based on health records of 1,612 patients at Mayo Clinic from found that overall survival was increased with repeat coronary artery bypass grafting versus patients who underwent  percutaneous coronary intervention: 


Survival at 10 years for repeat coronary artery bypass grafting patients reflected a 15% absolute improvement over matched patients who underwent percutaneous coronary intervention.


Repeat coronary artery bypass grafting patients, long-term mortality risk was reduced by 28% versus percutaneous coronary intervention patients in the Mayo study.


Previous studies have found similar long-term survival with repeat coronary artery bypass grafting, compared with percutaneous coronary intervention.
