This meta-analysis demonstrated that severe coronary disease-that is, LMD or 3VD-is more common in patients with ACS or stable coronary disease than generally perceived, and that simple and low-cost tools may help in the selection of the most appropriate therapeutic approach.

In patients with multivessel CAD, implementation of SYNTAX score with FFR seems to be a more rational approach for revascularization. F-SYNTAX score reclassifies a significant proportion of patients to a lower-risk profile, thus leading to a possible change of therapeutic strategy.
