Model 1: adjusted for age >70, hypertension, use of IV recombinant tissue plasminogen activator, dual antiplatelet therapy, poor reperfusion, National Institutes of Health Stroke Scale score on admission, baseline blood glucose >7 mmol/L, estimated glomerular filtration rate <60 L/min/1.73 m2, and posterior circulation.
Model 2: adjusted for age >70, hypertension, use of IV recombinant tissue plasminogen activator, dual antiplatelet therapy, poor reperfusion, National Institutes of Health Stroke Scale score on admission, baseline blood glucose >7 mmol/L, estimated glomerular filtration rate <60 L/min/1.73 m2, posterior circulation, and symptomatic intracranial hemorrhage.
hs-cTnI, high-sensitivity cardiac troponin.
