Untargeted lipidomics was performed on 16 subjects (8 CHD, 8 controls) randomly selected from the total enrolled population using UHPLC-Q-TOF\/MS. Lasso regression with ten-fold cross-validation was applied to screen key predictive factors, followed by multivariate logistic regression to construct a risk prediction model. The false discovery rate (FDR) was controlled using the Benjamini\u2013Hochberg procedure for multiple comparisons.

After FDR correction, the differential lipids remained statistically significant. CHD patients exhibited significant upregulation of RLP-C and sdLDL-C-related lipid components, while HDL2B-related lipids were markedly downregulated. KEGG pathway enrichment analysis revealed that differential lipids were mainly enriched in glycerophospholipid metabolism, choline metabolism in cancer, and fat digestion and absorption. Multivariate logistic regression identified Lp(a) (OR = 1.288), RLP-C (OR = 3.848), sdLDL-C (OR = 5.317), age (OR = 1.053), systolic blood pressure (OR = 1.075), and fasting plasma glucose (OR = 3.903) as independent risk factors for CHD, whereas HDL2B (OR = 1.416 \u00d7 10\n                      <jats:sup>\u22126<\/jats:sup>\n                      ) was a protective factor. In the validation cohort, the model achieved an AUC of 0.867 (95% CI: 0.8087\u20130.9252). Using an optimal cutoff of 0.4726 (Youden index = 0.628), the model demonstrated a sensitivity of 81.4% and a specificity of 81.4%.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>This study successfully constructed a multivariate logistic regression risk prediction model integrating novel lipid subfractions (sdLDL-C, RLP-C, HDL2B, Lp(a)) and routine clinical variables (age, SBP, FPG).
