    Abstract:
    BACKGROUND: Acute ischemic stroke (AIS) is a time-dependent treatable cause of morbidity and mortality. Despite the increasing stroke incidence in developing countries, parallel increasing stroke thrombolysis rates have not been documented. AIM: This study aims to determine trends in patient characteristics and rates of recombinant tissue plasminogen activator (rtPA) use in AIS patients in a tertiary care center in northern India. METHODS: All AIS patients presenting within 8 hours of symptoms onset from January 2011 to December 2015 were enrolled and analyzed. RESULTS: A total of 867 AIS patients presented within 8 hours of symptoms onset. Out of 593 eligible patients, 189 (31.87%) underwent intravenous thrombolysis (IVT) with rtPA within 4.5 hours of the window period. Patients (undergoing) IVT had onset-to-door times of 2 hours or less (23.81%), 2-3 hours (33.86%), and 3.0-4.5 hours (42.33%). IVT rates in 2 hours or less of symptom onset increased from 22% to 25% and IVT rates in 2-3 hours increased from 38.9% to 43.8%. Door-to-computerized tomographic time (median 27 versus 11 minutes, P = .0001) and door-to-needle time (median 83 versus 67 minutes, P = .011) improved, with a significant improvement of computerized tomography imaging time within 25 minutes of arrival (from 50% to 78.4%, P = .014). Post-IVT symptomatic hemorrhage was noted in 5 patients (2.65%). The median National Institutes of Health Stroke Scale score at presentation was 11, whereas a favorable modified Rankin Scale score (0-1) at 3 months was seen in 39.68%. CONCLUSIONS: Encouraging trends in IVT over the years may be indicative of increasing community awareness of stroke and improving quality of stroke care in developing countries such as India.
