Complete revascularization during coronary artery bypass grafting is linked with reduced major adverse events, according to a study published in Annals of Cardiac Anaesthesia.
In this study, researchers assessed 3,356 patients who underwent first-time isolated coronary artery bypass grafting procedures. They used Kaplan-Meier survival estimates, cumulative incidence function, and Cox regression to analyze outcomes.
According to the results, over 26% of patients had incomplete revascularization and over 73% had complete revascularization. The Kaplan-Meier estimates demonstrated that survival at one year (94.6% vs 92.5%) and five years (86.5% vs 82.1%) was notably better for patients who received complete revascularization. Moreover, freedom from major adverse cardiac and cerebrovascular events was appreciably higher for the complete revascularization cohort at both one year (89.2% vs 84.2%) and five years (72.5% vs 66.7%).
“Complete surgical revascularization of all angiographically stenotic vessels in patients with multivessel coronary artery disease is associated with fewer major adverse events,” the researchers concluded. They added that incomplete revascularization of nonmain-branch vessels “is not associated with survival or major adverse cardiac and cerebrovascular events.”
