Residual lipid-related proteomic and metabolomic signatures associated with major adverse cardiovascular events after revascularization in peripheral artery disease

Background

Patients with peripheral artery disease (PAD) remain at high risk for major adverse cardiovascular events (MACE) after lower-extremity revascularization. In contemporary practice, widespread lipid-lowering therapy may reduce the discriminatory value of conventional lipid parameters and clinically defined hyperlipidemia (HLD), leaving residual lipid-related molecular risk insufficiently characterized. This study aimed to characterize residual lipid-related proteomic and metabolomic signatures in PAD and examine their association with MACE after revascularization.
