Commentary: What Matters More—Method of Revascularization or Completeness?

This commentary succinctly reviews the 2021 coronary revascularization and the 2023 chronic coronary disease guidelines with relation to use of PCI and CABG in patients with ischemic cardiomyopathy and ejection fraction (EF) less than or equal to 35 percent, and reviews findings from Alzahrani et al. There is data suggesting the superiority of CABG compared to PCI in these populations, particularly with regards to completeness of revascularization and long-term outcomes that support keeping use of CABG in this particular patient population as a Class I recommendation.
