Abstract
Purpose

To investigate the level of sdLDL and the frequency of LDLR rs688 polymorphisms, as well as the correspondence between them, and to analyze the risk factors for stroke.

Methods

Between March 2019 and November 2019, 232 patients diagnosed with stroke and 96 health volunteers were enrolled in Quanzhou First Hospital. Subjects were divided into control group, ischemic stroke group (n=120) and hemorrhagic stroke group (n=112). The level of sdLDL and the genotypes and allele frequencies of LDLR rs688 were compared between groups, the correspondence was analyzed with Spearman method. Risk factors were analyzed with Binary logistic regression.

Results

The level of sdLDL was highest in ischemic group, followed by hemorrhagic stroke group and lowest control group. The differences of genotypes and allele frequencies of LDLR rs688 were significant in ischemic stroke group (p=0.0000 and 0.0000 respectively), while were not significant in hemorrhagic group (p=0.184 and .0137). There was no obvious correlation between the level of sdLDL and LDLR rs688 genotype by Spearman analysis (p=0.116).

Conclusion

Elevated sdLDL level and the C>T mutation of LDLR rs688 are independent risk factors for ischemic stroke, while they are not correlative to hemorrhagic stroke. The surveillance and regulatory of sdLDL level, the detection of LDLR rs688 gene polymorphisms may contribute to the prevention of ischemic stroke.

Resumen
Objetivo

Investigar el nivel de sdLDL y la frecuencia de los polimorfismos LDLR rs688, así como la correspondencia entre ellos, y analizar los factores de riesgo de accidente cerebrovascular isquémico.

Métodos

Entre marzo de 2019 y noviembre de 2019, 232 pacientes diagnosticados de accidente cerebrovascular y 96 voluntarios de salud se inscribieron en el Primer Hospital de Quanzhou. Los sujetos se dividieron en grupo de control, grupo de accidente cerebrovascular isquémico (n=120) y grupo de accidente cerebrovascular hemorrágico (n=112). El nivel de sdLDL y los genotipos y las frecuencias alélicas de LDLR rs688 se compararon entre grupos, y la correspondencia se analizó con el método de Spearman. Los factores de riesgo se analizaron con regresión logística-binaria.

Resultados

El nivel de sdLDL fue más alto en el grupo isquémico, seguido por el grupo de accidente cerebrovascular hemorrágico y el grupo de control más bajo. Las diferencias de genotipos y las frecuencias alélicas de LDLR rs688 fueron significativas en el grupo de ictus isquémico (p=0,0000 y p=0,0000, respectivamente), mientras que no lo fueron en el grupo de hemorragia (p=0,184 y p=0,0137). No hubo una correlación obvia entre el nivel de sdLDL y el genotipo rs688 de LDLR según el análisis de Spearman (p=0,116).

Conclusión

El nivel elevado de sdLDL y la mutación C>T de LDLR rs688 son factores de riesgo independientes para el accidente cerebrovascular isquémico, mientras que no son correlativos para el accidente cerebrovascular hemorrágico. La vigilancia y la regulación del nivel de sdLDL, así como la detección de polimorfismos del gen LDLR rs688, pueden contribuir a la prevención del accidente cerebrovascular isquémico.
