Abstract

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.

Resumen

Introducción: La ectasia arterial coronaria (EAC) es uno de los trastornos cardiovasculares poco frecuentes con un espectro clínico que va desde casos asintomáticos hasta infarto de miocardio. La aterosclerosis juega un papel fundamental en la patogenia de la CAE. Recientemente, se ha determinado que el índice aterogénico del plasma (AIP) es un fuerte marcador predictivo de aterosclerosis. El objetivo de este estudio fue investigar si existe una relación entre el CAE obstructivo y la PAI en pacientes con síndrome coronario agudo sin elevación del segmento ST (SCASEST).
Materiales y métodos: En este estudio retrospectivo, se examinaron retrospectivamente las historias clínicas electrónicas de los pacientes. Se incluyeron en el estudio un total de 213 pacientes con SCASEST. Los pacientes se dividieron en dos grupos según el CAE obstructivo y no obstructivo. El valor de AIP se comparó entre grupos y el análisis de regresión evaluó si es un indicador para predecir el riesgo de EAC obstructivo.
Resultados: Se encontró que el valor AIP era numérica y estadísticamente significativo en el grupo CAE obstructivo en comparación con el grupo CAE no obstructivo. El análisis de regresión logística multivariable identificó a la AIP como predictor de EAC obstructiva en pacientes con SCASEST en el análisis de la curva operativa del receptor, valores de AIP superiores a 0,33 tenían una sensibilidad del 90 % y una especificidad del 68 % para predecir EAC obstructiva en pacientes con SCASEST.
Conclusiones: Los valores de AIP se incrementaron en presencia de EAC obstructivo en pacientes con SCASEST. Nuestros hallazgos sugieren que AIP puede estar involucrado en la patogenia de CAE obstructivo.
