Summary
Cerebrovascular hemodynamics indexes (CVHI) show significant variations across different age groups, sexes, and measurement locations. These findings highlight the need for subgroup-specific reference ranges for accurate CVHI assessment.
Area of Science:
- Neurology
- Vascular Medicine
- Medical Imaging
Context:
- Cerebrovascular hemodynamics indexes (CVHI) are crucial for assessing brain blood flow.
- Establishing accurate reference ranges is essential for diagnosing cerebrovascular diseases.
- Previous studies may lack the large-scale, diverse population data presented here.
Purpose:
- To determine the reference ranges of cerebrovascular hemodynamics indexes (CVHI) in a large, diverse Chinese population.
- To identify variations in CVHI based on age, sex, geographical area, and measurement site.
- To provide data supporting the development of subgroup-specific CVHI reference values.
Summary:
- A prospective study analyzed CVHI in 14,480 participants across China.
- 95% confidence intervals for CVHI were calculated and stratified by age, sex, area, and check position.
- Significant differences in CVHI were observed across age groups, between sexes, and by carotid side, with no major area-specific variations.
Impact:
- The study reveals that standard CVHI reference ranges may not be universally applicable.
- Findings necessitate the estimation of CVHI reference ranges for specific demographic and anatomical subgroups.
- This research can inform clinical practice and improve the diagnosis and management of cerebrovascular conditions.
