Resumen: Objetivo: determinar los valores séricos de la enzima lecitina colesterol aciltransferasa en un grupo de mujeres postmenopáusicas, y establecer su relación con factores asociados a riesgo cardiovascular. Materiales y métodos: estudio descriptivo transversal prospectivo, correlacional, que incluyó 56 mujeres postmenopáusicas en quienes se evaluaron variables antropométricas y bioquímicas (perfil lipídico y glicemia basal) asociadas a riesgo cardiovascular y se correlacionaron con las concentraciones séricas de lecitina colesterol aciltransferasa. Resultados: los valores séricos promedio de dicha enzima fueron 7,89 ± 1,26 μg/ml. Las mujeres con valores de índice de masa corporal superior a 25 tienen niveles séricos de lecitina colesterol aciltransferasa significativamente mayores que aquellas que tienen índice de masa corporal normal. No se observaron relaciones significativas entre los niveles de lecitina colesterol aciltransferasa y las variables bioquímicas evaluadas. Conclusiones: este trabajo es uno de los primeros que evalúa los niveles séricos de lecitina colesterol aciltransferasa en mujeres postmenopáusicas del Caribe colombiano. Se encontró una relación significativa entre los niveles séricos de lecitina colesterol aciltransferasa y los valores de índice de masa corporal elevados. Se requieren nuevos estudios para entender mejor la relación entre los niveles séricos de lecitina colesterol aciltransferasa y el riesgo cardiovascular en mujeres postmenopáusicas. Abstract: Objective: To determine the serum levels of lecithin cholesterol acyltransferase in a group of postmenopausal women and to establish their relationship with factors associated with cardiovascular risk. Materials and methods: A descriptive, correlational and cross-sectional study was performed that included 56 postmenopausal women. Anthropometric and biochemical (lipid profile and baseline blood glucose) variables associated with cardiovascular risk were measured, and were correlated with the serum concentrations of lecithin cholesterol acyltransferase. Results: The mean serum level of lecithin cholesterol acyltransferase was 7.89 ± 1.26 μg/ml. The women with a body mass index greater than 25 had significantly higher serum levels of the enzyme than those that had a normal body mass index. No significant relationships were observed between the levels of lecithin cholesterol acyltransferase and the biochemical variables evaluated. Conclusions: This study is one of the first that has evaluated the serum levels of lecithin cholesterol acyltransferase in postmenopausal women of the Colombian Caribbean. A significant relationship was found between the serum levels of lecithin cholesterol acyltransferase and elevated values of the body mass index. Further studies are required for a better understanding of the relationship between the serum levels of lecithin cholesterol acyltransferase and cardiovascular risk in postmenopausal women.
