Abstract

ABSTRACT: Aims: The evidence of rt-PA intravenous thrombolysis in patients with minor ischemic stroke (MIS) is still controversial. This study aims to investigate the effect of rt-PA intravenous thrombolysis on the prognosis of patients with MIS. Methods: We continuously enrolled and analyzed patients with MIS admitted into our hospital within 24 h after symptom onset between January 2016 and December 2018, including 96 patients received intravenous thrombolysis within 4.5 h after symptom onset and 84 patients not received intravenous thrombolysis. A favorable long-term outcome was a 90-day mRS score of 0–1. Good short-term outcome was a 7-day NIHSS score of 0 or less than NIHSS onset. Results: There were no statistical differences between two groups of patients' age, gender, history of hypertension, coronary heart disease, atrial fibrillation, smoking, drinking, and baseline NIHSS score. Patients with history of stroke (22.62% vs. 10.42%, p < 0.05) and diabetes (46.43% vs. 22.92%, p = 0.01) were higher in group of non-thrombolysis. The difference of NIHSS score after 7 days was statistically different between the two groups ( p < 0.05), while there was no significant difference in 90-day mRS score. Logistic regression analysis indicated that the prognosis of patients was correlated with neutrophil ratio and CRP at admission. Conclusion: Patients with MIS received intravenous thrombolysis may be associated with earlier neurological improvement, but might has no significant effect on long-term prognosis. The level of neutrophil ratio and CRP at admission are risk factors determining the prognosis, which requires further research.
