  • Durable outcomes after Coronary Artery Bypass Graft (CABG) surgery require deliberate, clinician-led secondary prevention. Gaps in implementation highlight an important opportunity for coordinated system-level approaches integrated throughout the perioperative continuum to improve adherence.
  • Foundational pharmacologic therapy after CABG, which may include lifelong aspirin for graft patency, aggressive LDL-C lowering, and individualized guideline-directed cardioprotective therapies (β-blockers, ACE inhibitors/ARBs, SGLT2 inhibitors, GLP-1 RAs), is most effective when initiated early and sustained long-term.
  • Transitional care, in the form of coordinated handoffs at discharge, cardiac rehabilitation, telemedicine, and structured follow-up, supports implementation and adherence to secondary prevention strategies after CABG.
