The triglyceride-glucose index predicts peripheral artery disease complexity

Abstract

Background/aim: High levels of triglyceride (TG) and fasting blood glucose (FBG) values increase atherosclerosis risk. This study\revaluates the relationship between peripheral artery disease (PAD) severity and complexity, as assessed by TransAtlantic InterSociety\rConsensus-II (TASC-II) classification and the triglyceride-glucose (TyG) index.\rMaterials and methods: A total of 71 consecutive patients with PAD (males 93%, mean age 63.3 ± 9.7), who underwent percutaneous\rperipheral intervention were included retrospectively. The patients were divided into two groups according to the angiographically\rdetected lesions. Those with TASC A-B lesions were included in Group 1, and those with TASC C-D lesions were included in Group 2.\rTyG index was calculated as formula: ln[fasting TG (mg/dL) × fasting plasma glucose (mg/dL)/2].\rResults: There were 40 patients in Group 1 (90.3% men, with a mean age of 63.6 ± 9.3 years) and 31 patients in Group 2 (96.8% men,\rwith a mean age of 62.0 ± 8.6 years). In the majority of patients in both groups, the target vessels are iliac arteries and femoral arteries.\rIn Group 2, platelet count and TyG index were significantly high, according to Group 1. The TyG index was significantly correlated with\rTASC-II, Rutherford category, HbA1c, and HDL-C.\rConclusion: In this present study, we showed that the TyG index was an independent predictor of peripheral artery disease complexity,\raccording to TASC-II classification, for the first time in the literature.
