[Study on the scores of blood stasis syndrome of acute ischemic stroke and its correlation with TOAST subtypes].

UNLABELLED: OBJECTIVE To compare the differences in the scores of blood stasis syndrome (BSS) in three subtypes of acute ischemic stroke (AIS) based on modified Trial of Org 10172 in Acute Stroke Treatment (TOAST) criteria, and to explore the influencing factors of BSS. METHODS: Patients with AIS were classified by modified TOAST criteria. The BSS score was determined in 418 patients of atherosclerosis thrombosis (AT), cardioembolism (CE), and small artery disease (SAD) subtypes. The BSS scores were compared in the three subtypes. Univariate analysis and multivariable Logistic analysis were carried out to analyze the influencing factors of BSS. RESULTS: As for the BSS score, CE (120.08 +/- 14.91) > AT (79.56 +/- 11.43) > SAD (37.88 +/- 8.32), and there was statistical difference among different subtypes (P < 0.01). Univariate analysis indicated that age, heart disease, carotid stenosis, NIHSS, GCS, and multiple infarction positions had significant effects on BSS. Multiple Logistic regression analysis suggested that age (OR: 1.71, 95% CII: 1.13-2.74, P = 0.034), heart disease (OR: 2.05,95% CI: 1.52-4.15, P = 0.000), carotid stenosis (OR: 2.74, 95% CI: 1.65-4.55, P = 0.007), and multiple infarction positions (OR: 3.46, 95% CI: 2.16-6.62, P = 0.005) were independent influencing factors of BSS. CONCLUSIONS: Different TOAST subtypes of BSS had different BSS scores, which was helpful to indicate the reasons for BSS. Age, heart disease, carotid stenosis, and multiple infarction positions were independent influencing factors of BSS.
