Evaluation of the relationship between aspartate aminotransferase/alanine aminotransferase ratio and coronary slow-flow phenomenon

Abstract

Aim: To assess the correlation between the ratio of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) and slow coronary flow (SCF). Methods: A total of 119 patients with SCF and 121 age- and sex-matched patients with normal coronary flow were included in this retrospective cross-sectional study. Thrombolysis in myocardial infarction frame count of angiography images was marked by two interventionalists. In addition to AST and ALT levels, complete blood count; kidney, liver and thyroid function tests; age; sex; medication and medical history were recorded. Results: Significant spikes in AST/ALT ratio were discovered in the SCF group compared with the normal coronary flow group (p < 0.001). Thrombolysis in myocardial infarction frame count values were significantly higher in all coronaries for the SCF group compared with the normal coronary flow group (p < 0.001). Thrombolysis in myocardial infarction frame count values of the left anterior descending artery (r = 0.258; p < 0.001), left circumflex artery (r = 0.297; p < 0.001) and right coronary artery (r = 0.195; p = 0.002) were positively correlated with AST/ALT ratio. Conclusion: AST/ALT ratio is significantly correlated with SCF; therefore, this ratio may have predictive value.
