In the FREEDOM study, controlled optimal medical treatment was provided after both PCI and CABG.10 In addition, observational studies have shown that patients who had undergone CABG filled fewer prescriptions for statins, ACE inhibitors, and ARB blockers compared to those patients for whom PCI was performed.26 Moreover, compliance with guideline-directed medical therapy after revascularisation has been shown to be worse after CABG than PCI in clinical trials.27 Further studies are needed to clarify whether these findings apply also to revascularised patients with diabetes. Here, ACE is linked to diabetes mellitus.
