OBJECTIVE: Increased coronary thrombus load is a strong predictor of adverse cardiovascular (CV) outcomes. Identifying predictors of intracoronary thrombus burden may contribute to the management of ST-segment elevation myocardial infarction (STEMI). We aimed at evaluating the relationship between the atherogenic index (ATI) and coronary thrombus burden in patients presenting with STEMI.

PATIENTS AND METHODS: 139 patients who presented with STEMI and underwent primary percutaneous coronary intervention were included in this study. Angiographic thrombus burden was classified as previously defined in the myocardial infarction (TIMI) study group.

RESULTS: The patients were divided into two groups as those with high and low thrombus load. Independent predictors of high thrombus burden were ATI (OR: 4.23, 95% CI: 2.38-7.5; p<0.001), serum creatinine level (OR: 17.4, 95% CI: 3.03-101.4; p=0.001) and non-LAD involvement (OR: 0.363, 95% CI: 0.14-0.92; p=0.034). The association of ATI with thrombus load was independent from HDL and TGL levels.

CONCLUSIONS: The atherogenic index can be used as a reliable marker for increased coronary thrombus burden, which is associated with adverse CV outcomes.
