Abstract

Introduction     Intravenous recombinant tissue Plasminogen Activator (rt-PA) is standard treatment for the acute ischemic stroke patients that come to hospital within 4.5 hours since the symptoms occur (if no contraindication). Chonburi Hospital has had care system for these patients for several years. So, treatment outcomes and mortality in acute ischemic stroke patient treated with intravenous recombinant tissue Plasminogen Activator in Chonburi Hospital are studied.

Methods           The study was descriptive study. Population were acute ischemic stroke patients treated with intravenous recombinant tissue Plasminogen Activator in Chonburi Hospital from January 2018 to December 2019. Main outcomes of this study were short-term outcome by using NIHSS score, long-term outcome and mortality by using mRS score at 90 days after fibrinolysis in acute ischemic stroke patient treated with intravenous recombinant tissue Plasminogen Activator in Chonburi Hospital. Secondary outcome was association between patient factors and long-term outcomes of treatment.

Results             In 2018-2019, There were 294 patients (12.9% of acute ischemic stroke patients) treated with IV rt-PA in Chonburi Hospital. Improved short-term outcome was about 24.8%. Long-term outcome at 90 days after IV rt-PA had 32.4% for good outcome (mRS score 0-1) and 17.2% for mortality. Factors associated to good outcome at 90 days were age below 60-year-old (RR=1.51, 95%CI=1.03-2.21), age below 45-year-old (RR=2.01, 95%CI=1.29-3.13) and atrial fibrillation (RR=0.37, 95%CI=0.22-0.62). Factors associated to mortality at 90 days were atrial fibrillation (RR=2.70, 95%CI=1.63-4.45), door-to-needle time more than 45 minutes (RR=1.86, 95%CI=1.09-3.18) and more than 60 minutes (RR=2.35, 95%CI=1.43-3.88).               

Conclusion       The treatment outcomes and moortality in acute ischemic stroke patient treated with intravenous recombinant tissue Plasminogen Activator in Chonburi Hospital do not distinctively different compared with other studies. However, further study is needed to improve efficacy of acute ischemic stroke management.
