Summary

Coronary artery bypass grafting (CABG) remains the preferred revascularization strategy for patients with complex multivessel coronary artery disease. The left internal thoracic artery is universally accepted as the standard conduit for grafting the left anterior descending artery, but the long-term clinical benefit and safety of bilateral internal thoracic artery (BITA) grafting compared with single internal thoracic artery (SITA) grafting remain debated.

This retrospective cohort study compares long-term outcomes after BITA versus SITA grafting in consecutive adult patients undergoing first-time isolated CABG with at least two coronary grafts between May 1, 2017 and October 31, 2025 at Hospital Universitario de Gran Canaria Dr. Negrin. The primary endpoint is all-cause mortality during follow-up. Secondary outcomes include cardiovascular mortality, non-cardiovascular mortality, deep sternal wound infection, stroke, myocardial infarction, repeat coronary revascularization, and major adverse cardiovascular events (MACE).

Treatment groups will be balanced using stabilized inverse probability of treatment weighting derived from a multivariable propensity score model including clinically relevant baseline variables. Long-term outcomes will be analyzed using weighted Kaplan-Meier survival curves and Cox proportional hazards regression.
