Impact of Complete or Incomplete Revascularization for Left Main Coronary Disease: The Extended PRECOMBAT Study

BACKGROUND: Whether complete revascularization (CR) or incomplete revascularization (IR) may affect long-term outcomes after PCI) and coronary artery bypass grafting (CABG) for left main coronary artery (LMCA) disease is unclear.

Sumario:BACKGROUND: Whether complete revascularization (CR) or incomplete revascularization (IR) may affect long-term outcomes after PCI) and coronary artery bypass grafting (CABG) for left main coronary artery (LMCA) disease is unclear. OBJECTIVES: The authors sought to assess the impact of CR or IR on 10-year outcomes after PCI or CABG for LMCA disease. METHODS: In the PRECOMBAT (Premier of Randomized Comparison of Bypass Surgery versus Angioplasty Using Sirolimus-Eluting Stent in Patients with Left Main Coronary Artery Disease) 10-year extended study, the authors evaluated the effect of PCI and CABG on long-term outcomes according to completeness of revascularization. The primary outcome was the incidence of major adverse cardiac or cerebrovascular events (MACCE) (composite of mortality from any cause, myocardial infarction, stroke, or ischemia-driven target vessel revascularization). RESULTS: Among 600 randomized patients (PCI, n = 300 and CABG, n = 300), 416 patients (69.3%) had CR and 184 (30.7%) had IR; 68.3% of PCI patients and 70.3% of CABG patients underwent CR, respectively. The 10-year MACCE rates were not significantly different between PCI and CABG among patients with CR (27.8% vs 25.1%, respectively; adjusted HR: 1.19; 95% CI: 0.81-1.73) and among those with IR (31.6% vs 21.3%, respectively; adjusted HR: 1.64; 95% CI: 0.92-2.92) (P for interaction = 0.35). There was also no significant interaction between the status of CR and the relative effect of PCI and CABG on all-cause mortality, serious composite of death, myocardial infarction, or stroke, and repeat revascularization. CONCLUSIONS: In this 10-year follow-up of PRECOMBAT, the authors found no significant difference between PCI and CABG in the rates of MACCE and all-cause mortality according to CR or IR status.
