The effect of atherogenic plasma index on collateral development in patients with chronic coronary total occlusion
Aim: To demonstrate the correlation between coronary collateral circulation (CCC) and atherogenic plasma index (AIP), one of the factors associated with the formation of collateral vessels.
Methods: Hospital records of patients with chronic total occlusion (100% stenosis) in at least one coronary artery were evaluated. Triglycerides, HDL level, triglyceride/HDL ratio and atherogenic plasma index before coronary angiography were assessed for the 451 patients who met the study criteria.
Results: Comparison of the two groups in terms of laboratory findings showed that triglyceride/HDL ratio (5.04±3.13 vs 3.56±2.12, p<0.001) and AIP (0.63±0.25 vs 0.48±0.25, p<0.001) were higher with statistical significance in the weak collateral group. The ROC analysis revealed an association between weak collateral formation and atherogenic plasma index with 64.7% sensitivity and 66.2% specificity using a cut-off value of 0.58 for AIP. Accordingly, low AIP was found to be an independent predictor of good collateral artery formation.
Conclusion: This study suggests that a high atherogenic plasma index may be an independent factor associated with poor collateral formation.
