Özet

Background: Saphenous vein grafts (SVG) are frequently used in patients that have undergone coronary artery bypass graft (CABG) surgery. Objectives: To evaluate the relationship between atherogenic indexes and SVG stenosis. Methods: Altogether, 534 patients (27.7% women, mean age 65±8.4 years) that underwent CABG and elective coronary angiography were included in the study. Patients with at least one SVG stenosis ≥50% were allocated to the stenosis group SVG (+) (n=259) and patients without stenosis were categorized as SVG (-) (n=275). Atherogenic index of plasma (AIP) and atherogenic coefficient (AC) were calculated from the patients’ routine lipid parameters. The level of significance was p<0.05. Results: The number of patients with a history of hypertension (HT), diabetes mellitus (DM), stroke, and heart failure was significantly higher in the SVG (+) group than in the SVG (-) group. Total cholesterol, triglycerides, LDL-C were significantly higher and HDL-C was lower in the SVG (+) group than in the SVG (-) group. AIP (p<0.001) and AC (p<0.001) were significantly higher in the SVG (+) group than in the SVG (-) group. The receiver operating characteristic (ROC) analysis show that both AIP and AC were better than HDL-C, LDL-C and non-HDL-C at predicting SVG stenosis. In the multivariate analysis, history of DM, HT, stroke, heart failure (HF), number of saphenous grafts, HDL-C, LDL-C, non-HDL-C, AIP and AC were found to be independent risk factors for SVG stenosis. Conclusion: AIP and AC were independent predictors of SVG stenosis. Moreover, both AIP and AC have better performance in predicting SVG stenosis than LDL-C, HDL-C and non-HDL-C.
