急性缺血性脑卒中患者不同起病时点 NIHSS评分网络分析研究.

Objective To investigate the evolving patterns of relationship between NIHSS scores at different onset times in acute ischemic stroke through network analysis. Methods Data on NIHSS scores from 833 patients with acute ischemic stroke were collected. Network analysis methods were used to compare the between NIHSS scores within 72 hours of onset and on day 7. Resailts In the network analysis of NIHSS scores within 72 hours and on day 7 of onset in patients with acute ischemic stroke, the strongest node strength was observed in upper limb movement (Strength=1.48) and level of cognition (Strength二 1.75). The strongest edge weight was both in upper limb movement-lower limb movement (edge weight strength of 0.63 and 0.69). The top three nodes were upper limb movement, lower limb movement, and level of cognition. The network stability for the two time points were 0.75 and 0.67, and there was no significant difference between the two network models (P=0.38). Conclusion Motor function and level of cognition are important factors for the early course of acute ischemic stroke patients, and their correlation and prediction have high consistency in the acute period.
