CABG Mortality is Not Influenced by Prior PCI in Low Risk Patients

Background and Aims

An increasing number of patients referred for coronary artery bypass grafting (CABG) have had prior percutaneous coronary intervention (PCI). We sought to determine whether a relationship exists between increased postoperative mortality and morbidity following CABG procedure in patients with prior PCI.


Over an 18-month period, 950 patients having first-time isolated CABG were divided into two groups based on absence (Group A, 819 patients—86.21%) or presence of a prior PCI (Group B, 131 patients—13.79%).


In the prior PCI population, 74 patients (56.4%) had only one stent, and only 6.8% had multiple admissions for PCI. The overall incidence of three vessel disease in the entire patient population was only 65% and the average ejection fraction was 52%. Multivariate analysis demonstrated age (OR 1.080; 95% CI: 1.020 to 1.145; p = 0.009), left ventricular ejection fraction (OR 0.939; 95% CI: 0.901 to 0.978; p = 0.002), and emergency surgery (OR 0.138; 95% CI: 0.0.045 to 0.424; p = 0.001) as risk factors for 30-day mortality, while age (OR 1.059; 95% CI: 1.016 to 1.104; p = 0.007) and emergency surgery (OR 0.205; 95% CI: 0.078 to 0.537; p = 0.001) predicted major adverse cardiac events (MACE). Prior PCI did not influence mortality or MACE at 30 days.


In this study involving low risk patients, a PCI prior to CABG did not increase morbidity or mortality. doi: 10.1111/jocs.12141 (J Card Surg 2013;28:353–358)
