Correlation between plasma low-density lipoprotein level and hematoma enlargement and outcome in patients with intracerebral hemorrhage: A retrospective cohort study / 国际脑血管病杂志

ABSTRACT

Objective To investigate the relationship between plasma low-density lipoprotein (LDL) levels and hematoma enlargement of early intracerebral hemorrhage,outcome at 3 months and death.Methods A total of 316 patients with primary intracerebral hemorrhage were included in the study.Their general information was documented.The patients underwent CT scans at 6 and 24 hours after onset.The lipids,blood glucose,blood pressure,and the National Institutes of Health Stroke Scale (NIHSS) scores were detected at the same time.The patients were followed up for 3 months and their modified Rankin scale (mRS) scores and the number of death were recorded.Results The decreased plasma LDL level (odds ratio [OR] 0.323,95％ confidence interval [CI] 0.128 - 0.819; P =0.017) and the increased systolic pressure (OR 1.015,95％ CI 1.000 -1.029; P =0.043) were independently associated with the early hematoma enlargement.The decreased plasma LDL level (OR 0.253,95％ CI 0.102-0.629; P=0.003) and the increased blood glucose (OR 1.458,95％ CI 1.257 - 1.693; P ＜ 0.001 ) were the independent risk factors for poor outcome at 3 months after onset.The decreased plasma LDL level (OR 0.211,95％ CI 0.075 - 0.597; P =0.003),the increased bloot glucose level (OR 1.406,95％ CI 1.212 - 1.632; P =0.001) and the increased blood glucose level (OR 1.026,95％ CI 1.009 - 1.043; P =0.002) were the independent risk factors for death within 3 months.Receiver operating characteristic curves showed that the LDL level ＜ 2.58 mmol/L was an independent predictor for hematoma enlargement (sensitivity 71.79％,specificity 64.71％,positive predictive value 40.00％,and negative predictive value 87.50％ ).Conclusion The decreased plasma LDL level was the independent predictor for early hematoma enlargement,poor outcome and death at 3 months in patients with primary intracerebral hemorrhage.
