Associations of non-traditional lipid parameters with high-risk plaques characterized by optical coherence tomography in acute myocardial infarction culprit lesions

Key Points

• High-risk plaques are significantly associated with both non-traditional and traditional lipid parameters.
• The non-traditional ApoB/A1 ratio and non-HDL-C show linear associations with plaque morphology.
• Optical coherence tomography was used to characterize and assess the high-risk plaques in acute myocardial infarction lesions.
• Results indicate that combining these lipid assessments could enhance early identification and management of high-risk plaques.
