BACKGROUND AND AIMS: The impact of revascularization type, including coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI), on lipid control efficacy remains unclear. We aim to assess the associations of lipid levels with all-cause and cardiovascular mortality in patients undergoing PCI or CABG. METHODS: We used data from the ChinaHEART cohort and enrolled patients with a self-reported history of PCI or CABG. We employed Cox proportional hazards regression models to evaluate the associations between lipid levels and mortality. RESULTS: Our analysis included 29 003 participants, of whom 23 959 (82.6 %) undergoing PCI and 5044 (17.4 %) undergoing CABG. Over a median follow-up of 3.22 years, 1007 deaths were recorded, with 579 attributed to cardiovascular causes. Each 1 mmol/L increase in TC, LDL-C, and non-HDL-C was associated with multivariable-adjusted HRs of 1.16 (95 % CI 1.10,1.22), 1.23 (1.15,1.32) and 1.16 (1.10,1.23) for all-cause mortality, respectively. Similar results were observed in patients undergoing PCI, while no significant associations were found in patients undergoing CABG. CONCLUSIONS: Elevated lipid levels are associated with all-cause and cardiovascular mortality in revascularization patients. Suboptimal lipid control appears to have a more pronounced effect on mortality in patients undergoing PCI. The effects of elevated lipid levels on mortality in CABG patients may need a longer follow-up to manifest due to the more complex nature of the grafts and the long-term adaptation process.
