ObjectivesAlthough several studies have shown that interventions to lower blood lipid concentration may reduce the risk of coronary arterial disease and ischemic stroke, the correlation between serum lipid levels and hemorrhagic stroke remains controversial. To clarify any possible association between serum lipid and hematoma expansion, we examined various serum lipid indices in patients with and without early hematoma expansion.MethodsData of 572 intracerebral hemorrhage (ICH) patients from the cerebral small vessel disease cohort of Peking Union Medical College Hospital were retrospectively analyzed. Patients who finished the baseline brain computed tomography (CT) examination within 6 h post-ictus and the follow-up CT within 48 h after initial CT were included in the study. Hematoma expansion was delimited as an enlargement of hemorrhage volume over 33% or 12.5 mL between baseline and subsequent CT. Both uni- and multivariate logistic regression analyses were conducted to explore the association between early hematoma growth and various serum lipid indices, including triglycerides, total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), non-HDL-C, ratios of LDL-C/HDL-C and LDL-C/TC, as well as other demographic and clinical features.ResultsOut of 157 patients included in the analysis, hematoma growth occurred in 45 (28.7%). Only higher baseline systolic blood pressure was found to be correlated with an increased risk of hematoma growth based on both univariate (odds ratio [OR] 1.014, 95% confidence interval [CI]: 1.002-1.026, P = .024) and multivariate logistic regression analyses (OR 1.022, 95%CI: 1.008-1.037, P = .003). No associations were detected between the various serum lipid indices examined and other clinical features with a likelihood of early hematoma growth between groups or within various subgroups defined by different characteristics including age, gender, baseline Glasgow Coma Scale score, systolic blood pressure, intraventricular extension, and hematoma location.ConclusionsNo association between various indices of serum lipid and hematoma growth was identified among patients and subgroups with spontaneous ICH in the Chinese population; these findings may help to guide lipid management after ICH. However, further multi-centered, larger scale studies are expected to verify our results.Copyright © 2020 Elsevier Inc. All rights reserved.
