The document discusses the SYNTAXES Study which compared percutaneous coronary intervention (PCI) to coronary artery bypass grafting (CABG) for all-cause death in patients with complex coronary artery disease over 10 years. The study found no significant difference in all-cause death between PCI and CABG in the overall cohort, with rates of 27.0% for PCI and 23.5% for CABG. For patients with left main or three-vessel disease, CABG resulted in lower rates of all-cause death compared to PCI.
