Background And Purpose

Limited data were available about the combined impact of systolic blood pressure (SBP) and low-density lipoprotein cholesterol (LDL-C) levels on intracerebral hemorrhage (ICH) prognosis. The objective of this study is to explore whether the relationship between LDL-C and ICH outcomes was modified by SBP levels in a Chinese population.

Method

From August 1, 2015, to July 31, 2019, 75,443 ICH patients enrolled from the Chinese Stroke Center Alliance program were included in our study. Patients were divided into LDL-C levels of <70 mg/dL, 70-100 mg/dL, and ≥100 mmol/L. SBP was stratified as <140 mmHg, 140-180 mmHg, and ≥180 mmHg. The primary outcome was the occurrence of hematoma expansion (HE), and the second outcome was in-hospital mortality. Correlation between LDL-C levels and SBP on ICH outcomes were assessed by logistic regression.

Conclusion

Lower LDL-C levels (<70 mg/dL) are related to a higher risk of HE and in-hospital mortality confined to ICH patients with elevated SBP (≥140 mmHg).

Main results

6,116 (8.1%) and 1,576 (2.1%) patients suffered HE and in-hospital mortality. Compared with the ≥100 mg/dL group, patients with LDL-C concentrations under 70 mg/dL had a 19% and 24% increase in the relative risk of HE (crude OR 1.19, 95% CI 1.11-1.28) and in-hospital mortality (crude OR 1.24, 95% CI 1.08-1.42). When SBP was added as a stratification variable, the above-mentioned association was attenuated in patients under a threshold SBP of 140 mmHg (P > 0.05). However, no statistical interaction was detected between SBP and LDL-C levels.
