Rate of Incomplete Revascularization Following Coronary Artery Bypass Grafting at a Single Institution Between 2007 and 2017
Section snippets
Methods
This retrospective cohort study was approved by the Institutional Review Board of Allina Health and Abbott Northwestern Hospital. A review of patients with multi-vessel CAD was performed based on the date of CABG operations at the Minneapolis Heart Institute at Abbott Northwestern Hospital. Two cohorts were analyzed, a historical cohort consisting of all patients who underwent elective and solitary CABG in 2007 (n = 291) and a contemporary cohort consisting of all patients who underwent CABG in
Results
The historical cohort was composed of 291 consecutive patients who underwent elective and isolated CABG in 2007. The contemporary cohort was composed of 290 consecutive patients who underwent elective and isolated CABG in 2017.
In the historical cohort, 52 (17.9%) operations were classified as incomplete while in the contemporary cohort, 82 (28.3%) operations were classified as incomplete resulting in a significant increase in incomplete revascularization (p = 0.003) over the 10-year period (
Discussion
We observed that the incidence of incomplete revascularization following CABG significantly increased over a 10-year period (2007 to 2017) from 17% to 28%. This occurred despite a 50% decline in off-pump CABG in the 2017 group which has previously been associated with greater incomplete revascularization in several studies.6,12 Subjects in the 2007 group were more likely to be smokers and had a greater incidence of peripheral vascular disease while subjects in the 2017 cohort were older, more
