Exploring the Relationship between ICAS Plaque Characteristics,Vascular Wall Parameters,and Ischemic Stroke Incidence Based on HR-MR-VWI
Objective To analyze the relationship between ICAS plaque characteristics,vessel wall parameters and ischemic stroke based on HR-MR-VWI.Methods 100 patients with suspected ischemic stroke admitted to our hospital from December 2018 to December 2020 were selected as the observation group and 50 healthy subjects were selected as the control group;all subjects underwent HR-MR-VWI scanning;The patients were followed up for 2 years,and their stroke events were recorded,and they were divided into a stroke subgroup and an asymptomatic subgroup according to whether they had a stroke;Spearman's correlation test and logistics regression model were used to analyze the impact and risk factors of ischemic stroke.Results The LARL,OWAMLN,and WAMLN in the observation group were higher than control group statistically,LAMLN were obvious lower than the control group statistically(P＜0.05).The stenosis rate,plaque burden,and remodeling index levels were obvious higher than asymptomatic group,and the LAMLN level was obvious lower than that of the asymptomatic group,and the difference was statistically obvious(P＜0.05);LARL,OWAMLN,WAMLN,stenosis rate,plaque The load and remodeling index were obvious positively correlated with the incidence of ischemic stroke,and LAMLN was obvious negatively correlated with the incidence of ischemic stroke,and there was statistical obvious(P＜0.05);high LARL,low LAMLN,high OWAMLN,high WAMLN,high stenosis rate,high plaque burden and high remodeling index were independent risk factors for ischemic stroke,and there was statistical obvious(P＜0.05).Conclusion Based on HR-MR-VWI detection of plaque characteristics and vessel wall parameters in patients with ICAS,they are independent risk factors affecting the incidence of ischemic stroke.
