Association of albumin levels with the risk of intracranial atherosclerosis

Abstract

ObjectiveIntracranial artery stenosis from atherosclerosis is one of the etiologies of ischemic stroke. There is a correlation between serum albumin level and atherosclerosis. We aimed to investigate whether serum albumin level is related to intracranial atherosclerosis and its significance.MethodsA retrospective analysis of 150 individuals who underwent cervical cerebral angiography after admission, including clinical data, imaging data, and laboratory data. Since atherosclerosis cannot be used as a good quantitative indicator, we choose the degree of arterial stenosis to reflect atherosclerosis. SPSS 24 software was used for data analysis, and P < .05 was considered statistically significant.ResultsUnivariate analysis showed that age, diabetes, and serum albumin level were risk factors for intracranial atherosclerosis (P < .05). Multivariate analysis showed that diabetes and serum albumin levels were independent risk factors for intracranial atherosclerosis (P< 0.05). The average serum albumin level in the non-severe group was 39.80 g/L, and the average serum albumin level in the severe group was 37.60 g/L. The area under the ROC curve of serum albumin was 0.667 (95%CI 0.576–0.758, P = .001), the cutoff value was 0.332176, the sensitivity was 75.9%, and the specificity was 57.3%.ConclusionSerum albumin level is an independent risk factor for intracranial atherosclerosis, and provides a new direction for clinical prevention and treatment.
