“…In EXCEL [8], which studied low to intermediate left main complexity, the incidence of death, stroke, or MI (including periprocedural MI) was similar in the PCI and CABG cohorts (22.0% vs 19.2%; 95% CI, -0.9 to 6.5; P = 0.13). Conversely, in the NOBLE study [9], which studied all-comer left main complexity, the incidence of death, MI (excluding peri-procedural MI), repeat revascularisation, and stroke was higher for PCI (28% vs 19%; p = 0.0002). However, neither study showed an excess of CV death with PCI.…”
