Association Between Low-Density Lipoprotein-Cholesterol Level and Risk of Intracranial Atherosclerotic Stenosis: Results From the APAC Study.
Background: It is unknown whether plasma low-density lipoprotein-cholesterol level (LDL-C) can predict the occurrence of intracranial atherosclerotic stenosis (ICAS), especially asymptomatic (A)ICAS. This study investigated whether LDL-C level is independently associated with AICAS.
Methods: The Asymptomatic Polyvascular Abnormalities Community study is an ongoing community-based, prospective, long-term follow-up observational study with 3387 participants. AICAS was diagnosed by transcranial Doppler ultrasonography. The participants were divided into 3 groups based on LDL-C level. Cox regression was used to evaluate the association between LDL-C level and incidence of AICAS.
Results: During 2 years of follow-up, 9.98% of participants were diagnosed with AICAS. The incidence of AICAS (person-years with 95% CI) was 4.99% (4.48%-5.50%). AICAS incidence did not increase with increasing LDL-C level. Compared with the <2.6 mmol/l subgroup, the incidence of asymptomatic ICAS was not significantly higher in the 2.6 to 3.4 and >3.4 mmol/l subgroups after adjusting for confounding factors (hazard ratio=0.95, 95% CI: 0.86-1.03 and hazard ratio=0.96, 95% CI: 0.84-1.10, respectively).
Conclusions: LDL-C is not an independent predictor of AICAS incidence in the Chinese population.
期刊介绍：
The Neurologist publishes articles on topics of current interest to physicians treating patients with neurological diseases. The core of the journal is review articles focusing on clinically relevant issues. The journal also publishes case reports or case series which review the literature and put observations in perspective, as well as letters to the editor. Special features include the popular "10 Most Commonly Asked Questions" and the "Patient and Family Fact Sheet," a handy tear-out page that can be copied to hand out to patients and their caregivers.
