BACKGROUND: Revascularization for the treatment of coronary artery disease (CAD) is advancing rapidly and is used increasingly in old patients. This study aimed to compare the efficacy and safety of revascularization with drug therapy in CAD patients aged over 80 years at a real-world clinical setting.

METHODS: A total of 501 CAD patients aged over 80 years were consecutively enrolled from January 2011 to January 2016 in Anzhen Hospital (Beijing, China), Capital Medical University. The patients were treated with percutaneous coronary intervention (PCI) (n=283), coronary artery bypass grafting (CABG) (n=106), or drug therapy (n=112). All-cause mortality, cardiovascular-related mortality, readmission rate, and Seattle Angina Questionnaire (SAQ) score were compared between the three treatment methods.

RESULTS: A total of 411 patients (82.04%) were followed with a median duration of 25 months. All-cause mortality and cardiovascular-related mortality in the drug therapy group were significantly higher than the PCI and CABG groups (both P<0.05). Readmission rate for cardiovascular events in the CABG group was significantly lower than the PCI and drug therapy groups (both P<0.05). Scores of physical limitation, angina frequency, treatment satisfaction, and disease perception of the SAQ in the PCI and CABG groups were significantly higher than the drug therapy group (both P<0.05). Scores of angina stability did not differ significant between the three groups (P=0.127).

CONCLUSIONS: Revascularization is superior to drug therapy in efficacy and safety in the treatment of oldest-old patients with CAD.
