Relation of Carotid Artery Intima-Media Thickness to Stroke Severity and Disability after Noncardioembolic Ischemic Stroke
비심인성허혈뇌졸중의 중증도와 장애정도에 대한 경동맥 내막-중막두께와의 연관성
Abstract
Background
Increased carotid artery intima-media thickness (IMT) has been identified as an independentand early marker of generalized atherosclerosis, and is associated with increased risk ofischemic stroke. This study was performed to investigate the relation of carotid artery IMT to strokeseverity and clinical disability in patients with acute noncardioembolic ischemic stroke.
Methods
Subjects were 381 patients with acute noncardioembolic ischemic stroke. The carotid arterial wallthickness was measured using high resolution B-mode ultrasound. National Institute of HealthStroke Scale (NIHSS) and modified Rankin Scale (mRS) were used to assess the severity of neurologicaldeficit on admission and clinical disability on discharge respectively. Univariate regressionanalysis was performed to evaluate the relationship between carotid artery IMT and clinicaloutcome.
Results
Carotid artery IMT was significantly correlated with NIHSS (R2=0.0102, p=0.049)and mRS scores (R2=0.0297, p=0.001).

Conclusion
s

Measurement of carotid artery IMT may behelpful in predicting the degree of clinical outcome in patients with acute ischemic stroke.
