Introduction: Coronary artery ectasia (CAE) is one of the uncommon cardiovascular disorders with a clinical spectrum ranging from asymptomatic cases to myocardial infarction. Atherosclerosis plays a pivotal role in the pathogenesis of CAE. Recently, it has been determined that the atherogenic index of plasma (AIP) is a strong predictive marker for atherosclerosis. The aim of this study was to investigate whether there is a relationship between obstructive CAE and AIP in patients with non-ST segment elevation acute coronary syndrome (NSTE-ACS).

Materials and methods: In this retrospective study, hospital electronic patient records were retrospectively examined. A total of 213 NSTE-ACS patients were included in the study. Patients were divided into two groups according to non-obstructive and obstructive CAE. The AIP value was compared between groups and regression analysis evaluated whether it is an indicator to predict the risk of obstructive CAE.

Results: The AIP value was found to be numerically and statistically significant in the obstructive CAE group compared to the non-obstructive CAE group. The multivariate logistic regression analysis identified AIP as a predictor of obstructive CAE in NSTE-ACS patients in the receiver operating curve analysis, AIP values above 0.33 had 90% sensitivity and 68% specificity to predict obstructive CAE in NSTE-ACS patients.

Conclusions: AIP values were increased in the presence of obstructive CAE in NSTE-ACS patients. Our findings suggest that AIP may be involved in the pathogenesis of obstructive CAE.
