The effect of thrombolytic therapy and TOAST and OCSP classification on the short-term prognosis of patients with acute ischemic stroke / 中华急诊医学杂志

ABSTRACT

Objective:To investigate the short-term prognosis of patients with acute ischemic stroke after thrombolysis with alteplase and the relationship between TOAST and OCSP classification and prognosis of patients with acute ischemic stroke.Methods:A retrospective analysis was conducted in 193 patients with acute ischemic stroke in the Emergency Department of our hospital from January 2019 to June 2020, including 158 males and 85 females, aged 69.46±13.02 years. Among them, 66 patients were treated with alteplase thrombolysis and 127 patients were not treated with thrombolysis. The short-term prognosis of thrombolytic patients and non-thrombolytic patients were compared; the influence of TOAST classification and OCSP classification on the prognosis of acute ischemic stroke was analyzed.Results:There was no significant difference in the length of hospital stay between the thrombolytic group and the non-thrombolytic group ( P>0.05), while the improvement rate of NIHSS score, GCS score, and mRS score were significantly different at admission and discharge ( P<0.05). According to TOAST classification, 78 cases (40.41%) were LAA, 100 cases (51.81%) were SAO, 9 cases (4.66%) were CE, 3 cases (1.55%) were SOE, and 3 cases (1.55%) were SUE; SAO type accounted for the highest proportion (51.81%), the improvement rate of NIHSS score at admission and discharge was significantly different from that of the LAA patients ( P<0.05), and the short-term prognosis was the best. According to OCSP classification, 39 cases (20.21%) were LACI, 64 cases (33.16%) were PACI, 55 cases (28.50%) were POCI, 35 cases (18.13%) were TACI, among which the PACI patients had the highest proportion, while the improvement rate of NIHSS score in the LACI patients was significantly different at admission and discharge compared with other types of patietns ( P<0.05), and the short-term prognosis was good. Conclusions:The short-term prognosis and symptom improvement of patients with acute ischemic stroke after alteplase thrombolytic therapy are obvious. TOAST classification and OCSP classification have certain prediction effects and play clinical reference roles on the short-term prognosis of patients with acute ischemic stroke.
