Aim:
A reduction in low-density lipoprotein cholesterol (LDL-C) is beneficial for vascular diseases; however, lower LDL-C levels may be associated with an increased risk of spontaneous intracerebral hemorrhage (sICH). The present study investigated the relationship between the LDL-C levels and in-hospital mortality after sICH using data from the Juntendo Registry of Spontaneous Intra-Cerebral Hemorrhage (J-ICH registry).
Methods:
Patients aged ≥ 20 years with non-traumatic sICH admitted to five Juntendo-affiliated hospitals between September 2016 and December 2019 were enrolled in this study. The relationships between the LDL-C levels and in-hospital mortality, statin therapy, and antithrombotic therapy were analyzed.
Results:
Among the 1,017 patients with sICH, lower LDL-C levels were associated with older age, a lower BMI, a larger hematoma volume, more severe neurological deficits, and a higher in-hospital mortality. A logistic regression analysis confirmed that LDL-C ＜100 mg/dL independently increased the risk of in-hospital death, along with age, the NIHSS score, hematoma volume, and intraventricular hemorrhage. Subgroup analyses showed that the association between low LDL-C levels and mortality was particularly evident in patients with deep/infratentorial intracerebral hemorrhage, those managed without surgery, and those without prior statin use. Prior statin use was associated with a potential protective effect against in-hospital mortality and hematoma volume.
Conclusion:
This study demonstrated that lower LDL-C levels were associated with a higher in-hospital mortality after sICH, whereas prior statin use was not associated with poorer outcomes and may instead offer a protective effect.
