In this single-center, nonrandomized study, there were no significant differences in cardiac death or myocardial infarction and MACCE between CABG and PCI for the treatment of left main coronary artery disease in octogenarians after a mean follow-up of 2 years. Baseline EuroSCORE was the most important predictor of MACCE regardless of the type of revascularization. Randomized studies comparing both revascularization strategies in this high-risk coronary population are warranted.

In patients with moderate coronary lesions and borderline FFR measurements deferral of revascularization was associated with a higher rate of MACE (CR) and a higher prevalence of angina at follow-up, especially in those with previous MI in the territory evaluated by FFR. Further prospective randomized studies should confirm whether or not an FFR cut-off point of 0.80 instead of 0.75 would be more appropriate for deferring CR in these cases.
