The researchers found that, compared with PCI, CABG was associated with a significant 8% decreased risk of death in the study population overall and a significant 12% decreased risk of death among diabetics and an 18%, 16%, and 15% decreased risk for patients with a history of tobacco use, heart failure, or peripheral artery disease. Over five years, the overall predicted difference in survival between CABG and PCI was 0.053 life-years. The largest predicted differences in survival were seen for patients with diabetes, heart failure, peripheral artery disease, or tobacco use. For patients with none of these factors, survival was slightly better after PCI.

“This study provides strong evidence that clinical characteristics modify the comparative effectiveness of CABG and PCI on mortality, especially for diabetes,” the authors wrote. “Our study suggests that additional factors, particularly smoking, peripheral arterial disease, and heart failure, also modify the CABG-PCI treatment effect.”
