Risk factors related with the prognosis of patients with acute cerebral infarction after intravenous thrombolysis by alteplase

Objective To investigate the risk factors related with the prognosis of patients with acute cerebral infarction after intravenous thrombolysis by alteplase in 90 days.Methods Forty patients with acute cerebral infarction treated by intravenous thrombolysis with aheplase were selected and assigned into good outcome group [modified Rankin scale (mRS) 0-1 score] and poor outcome group (mRS 2-6 scores) according to mRS at 90 days.The risk factors were compared between two groups.Results Poor outcome group (22 cases) comparing with good outcome group (18 cases),the values of age [ (64.64±11.30) years vs.(58.94±10.47) years ],onset to therapy time(OTT) [(376.73±316.32)min vs.( 176.00±59.74) min],National Institutes of Health stroke scale (NIHSS) score before thrombolysis [ ( 16.73±8.46)scores vs. (11.22±5.20) scores],maximum of systolic blood pressure (SBPmax) in the first 24 hours after thrombolysis[ ( 186.59±24.79 )mm Hg ( 1 mm Hg =0.133 kPa) vs.( 169.00±23.04) mm Hg] and systolic blood pressure variability (SBPV)[(17.11±3.90) mm Hg vs.(13.33±4.97) mm Hg] had significant differences (P＜ 0.05).Conclusion The values ofage,OTT,NIHSS score before thrombolysis,SBPmax and SBPV in the first 24 hours after thrombolysis are related with the prognosis of patients with acute cerebral infarction after intravenous thrombolysis by altcplase in 90 days.
