    BackgroundIntravenous thrombolysis can significantly improve the neurological function of patients with acute ischemic stroke. However, the expected early dramatic recovery (EDR) of neurological function after thrombolysis is not achieved in some patients with branch atheromatous disease (BAD). Here we evaluated the factors associated with EDR after thrombolysis in BAD patients.MethodsWe conducted a retrospective study on 580 consecutive BAD patients. All patients met the diagnostic criteria of BAD and received intravenous recombinant tissue-type plasminogen activator (rt-PA). EDR was defined when the improvement of National Institutes of Health Stroke Scale (NIHSS) score was >8 points within 2 or 24 hours after rt-PA, or the total NIHSS score was 0 or 1. The factors associated with EDR were analyzed with multivariate logistic regression analysis.ResultsAmong 580 patients, the incidence of EDR was 35.2% (204 cases). Compared with patients without EDR, patients with EDR had lower incidence of diabetes (15.7% vs 29.3%, P < .001), lower NIHSS scores at 2 and 24 hours after rt-PA (P < .001), less cerebral hemorrhage (0% vs 5.3%, P = .001), and shorter onset to treatment time (OTT) (P < .001). Multivariate logistic regression analysis in propensity score-matched cohort showed that EDR was associated with OTT (adjusted OR = 0.994; 95% CI, 0.989-0.999) and NIHSS score after rt-PA (adjusted OR = 0.768; 95% CI, 0.663-0.890). Notably, diabetes (adjusted OR = 0.477, 95% CI, 0.234-0.972) was an independent factor related to EDR of neurological function in BAD patients. In the subgroup analysis, a lower incidence of diabetes (adjusted OR = 0.205, 95% CI: 0.059-0.714, P = .013) and a lower NIHSS score after thrombolysis in patients with paramedian pontine infarction (adjusted OR = 0.809, 95% CI: 0.656-0.997, P = .047) were significantly associated with EDR.ConclusionDiabetes is not conducive to EDR of neurological function in patients with BAD, especially in patients with paramedian pontine infraction. Low NIHSS score and short OTT after thrombolysis may be closely related to EDR after intravenous thrombolysis.Copyright © 2023 the Author(s). Published by Wolters Kluwer Health, Inc.
