56 patients had AST/ALT ratio greater than 2, while 59 patients had AST/ALT ratio less than 2. STEMI patients with AST/ALT ratio greater than 2 had a significantly higher prevalence of total vessel occlusion (TIMI thrombus grade 5), and there is a significant association between high AST/ALT ratio and TIMI thrombus grade 5 on both univariate and multivariate analysis. However, there is no statistically significant difference between both groups as regarding the coronary artery complexity as assessed by SYNTAX and Genseni scores.

Conclusion

Patients with AST/ALT ratio greater than 2 are strongly associated with high thrombus burden (thrombus burden of 5) on TIMI thrombus grade before primary PCI.
