Insights
The total burden of cerebral small vessel disease (CSVD) is linked to both initial and recurring lacunar infarction (LI). Higher CSVD scores predict LI onset and progression, highlighting its role in stroke development.
Area of Science:
- Neurology
- Radiology
- Cardiovascular Research
Background:
- Cerebral small vessel disease (CSVD) encompasses various pathological changes in small arteries, arterioles, and capillaries of the brain.
- Lacunar infarction (LI) is a common type of ischemic stroke resulting from the occlusion of small penetrating arteries.
- Understanding the relationship between CSVD burden and LI occurrence is crucial for stroke prevention and management.
Purpose of the Study:
- To investigate the association between the total cerebral small vessel disease (CSVD) burden and the incidence of first-ever and recurrent lacunar infarction (LI).
Main Methods:
- Retrospective analysis of 271 patients with acute cerebral infarction.
- Calculation of total CSVD score based on imaging findings (WMH, EPVS, lacunar).
- Classification into LI and large-artery atherosclerosis (LAA) groups; LI group further divided into recurrent and non-recurrent subgroups.
- Logistic regression and ROC curve analysis to identify risk factors and predictive value.
Main Results:
- LI patients (56.46%) showed significant differences in SBP, DBP, UA, ALB, TG, FIB, TP, WMH, EPVS, and total CSVD score compared to LAA patients.
- Total CSVD score, WMH, EPVS, and UA were independent risk factors for first-ever LI; FIB was protective.
- Recurrent LI cases had higher rates of smoking, WMH, EPVS, CMB, and total CSVD score.
- Total CSVD score predicted LI recurrence with an AUC of 0.832.
Conclusions:
- The total CSVD burden is significantly correlated with both first-ever and recurrent lacunar infarction.
- Elevated CSVD burden is an independent risk factor for lacunar infarction.
- The total CSVD score shows predictive value for lacunar infarction onset and progression.
Objective:
To investigate the relationship between the total cerebral small vessel disease (CSVD) burden and the occurrence of first-ever and recurrent lacunar infarction (LI).
Methods:
This study included 271 patients with first-ever acute cerebral infarction hospitalized in the Department of Neurology, Affiliated Hospital of Qingdao University, between January 2019 and January 2024. The total CSVD score was calculated based on imaging findings. Patients were classified into LI and large-artery atherosclerosis (LAA) groups according to infarct size and large-vessel stenosis severity. The LI group was further subdivided into recurrence and non-recurrence subgroups. Clinical and imaging data were compared between groups. Logistic regression was used to identify risk factors for first-ever and recurrent LI, and the predictive value of the total CSVD score for LI recurrence was assessed using receiver operating characteristic (ROC) curve analysis.
Results:
The LI group comprised 153 patients (56.46%), and the LAA group included 118 patients (43.54%). Significant differences were observed in systolic blood pressure (SBP), diastolic blood pressure (DBP), uric acid (UA), albumin (ALB), triglycerides (TG), fibrinogen (FIB), total protein (TP), white matter hyperintensities (WMH), enlarged perivascular spaces (EPVS), lacunar, and total CSVD score between groups (p < 0.05). Logistic regression identified total CSVD score, WMH, EPVS, and UA as independent risk factors for first-ever LI, while FIB acted as a protective factor (p < 0.05). Among 140 LI patients, 28 experienced recurrence. Recurrent LI patients exhibited higher rates of smoking, WMH, EPVS, cerebral microbleeds (CMB), and total CSVD score compared to non-recurrent cases (p < 0.05). ROC analysis demonstrated that the total CSVD score predicted LI recurrence with the area under the curve (AUC) of 0.832.
Conclusion:
The total CSVD burden correlates with both first-ever and recurrent LIs. It is an independent risk factor for LI and may predict LI onset and progression.
