Abstract

BACKGROUND: The aim of this study was to investigate the correlations of C-reactive protein (CRP), interleukin-6 (IL-6), and insulin resistance (IR) with cerebral infarction in hypertensive patients.

MATERIAL AND METHODS: A total of 80 patients with cerebral infarction admitted to our hospital from March 2016 to November 2017 were selected and divided into 2 groups according to the diameter of cerebral infarction, namely, lacunar cerebral infarction group (n=40) and cerebral infarction group (n=40). The levels of high-sensitivity CRP (hs-CRP) and IL-6, homeostasis model assessment of IR (HOMA-IR) index and blood pressure level were compared between the 2 groups. The correlations of hs-CRP level, IL-6 level, and IR with the diameter of cerebral infarction, as well as the relationships of hs-CRP level and IR with the neurological function score after cerebral infarction were analyzed.

RESULTS: The levels of hs-CRP and IL-6 in the cerebral infarction group were significantly higher than those in the lacunar cerebral infarction group (P<0.05). The cerebral infarction group had a markedly higher HOMA-IR index than the lacunar cerebral infarction group (P<0.05), but it had remarkably decreased systolic blood pressure and diastolic blood pressure compared with those in the lacunar cerebral infarction group (P<0.05). There were positive correlations of hs-CRP level, IL-6 level, and IR with the diameter of cerebral infarction (P<0.05). The hs-CRP level and IR had positive correlations with the neurological function score after cerebral infarction (P<0.05).

CONCLUSIONS: In hypertensive patients complicated with cerebral infarction, the body’s inflammatory factors, and IR are positively correlated with the diameter of cerebral infarction, as well as the neurological prognosis of the patients.
