    Abstract

    BACKGROUND The optimal revascularization strategy for the elderly with complex coronary artery disease remains unclear.

    OBJECTIVES The goal of this study was to investigate 10-year all-cause mortality, life expectancy, 5-year major adverse cardiac or cerebrovascular events (MACCE), and 5-year quality of life (QOL) after percutaneous coronary intervention (PCI) or coronary artery bypass graft (CABG) in elderly individuals (>70 years old) with 3-vessel disease (3VD) and/or left main disease (LMD).

    METHODS In the present pre-specified analysis on age of the SYNTAX Extended Survival study, 10-year all-cause death and 5-year MACCE were compared with Kaplan-Meier estimates and Cox proportional hazards models among elderly or nonelderly patients. Life expectancy was estimated by restricted mean survival time within 10 years, and QOL status according to the Seattle Angina Questionnaire up to 5 years was assessed by linear mixed-effects models.

    RESULTS Among 1,800 randomized patients, 575 patients (31.9%) were elderly. Ten-year mortality did not differ significantly between PCI and CABG in elderly (44.1% vs. 41.1%; hazard ratio [HR]: 1.08; 95% confidence interval [CI]: 0.84 to 1.40) and nonelderly patients (21.1% vs. 16.6%; HR: 1.30; 95% CI: 1.00 to 1.69; p(interaction) = 0.332). Among elderly patients, 5-year MACCE was comparable between PCI and CABG (39.4% vs. 35.1%; HR: 1.18; 95% CI: 0.90 to 1.56), whereas it was significantly higher in PCI over CABG among nonelderly patients (36.3% vs. 23.0%; HR: 1.69; 95% CI: 1.36 to 2.10; p(interaction) = 0.043). There were no significant difference in life expectancy (mean difference: 0.2 years in favor of CABG; 95% CI: -0.4 to 0.7) and 5-year QOL status between PCI and CABG among elderly patients.

    CONCLUSIONS Elderly patients with 3VD and/or LMD had comparable 10-year all-cause death, life expectancy, 5-year MACCE, and 5-year QOL status irrespective of revascularization mode. (C) 2021 by the American College of Cardiology Foundation.
