RESUMO
The use of intravenous thrombolytic therapy (ITT) in acute ischemic stroke (AIS) patients is still debated in China. We present the analysis of clinico-demographic retrospective data of 646 AIS patients that were treated by alteplase ITT at our hospital. The data collected included age, gender, education, income, drug use before disease onset, and awareness of stroke/ITT. The risk factors studied were hypertension, diabetes, hyperlipidemia, atrial fibrillation, coronary heart disease, cerebral infarction, transient ischemic attack, valvular heart disease, thyroid disease, migraine, asymptomatic carotid stenosis, family history of stroke, hyperhomocysteinemia, smoking, drinking, and gingivitis. Pre-ITT patient data included blood pressure and time from onset to hospital. Post-ITT patient data included National Institutes of Health Stroke Scale (NIHSS) scores, clinical outcome, revascularization, hemorrhage, healing rate, and 90-day mortality. Hospital management information included monthly ITT cases, discharges, bed turnaround times, length of hospital stay, bed utilization, drug ratio, massive cerebral infarction decompressive craniectomy, and social impact. Prognosis evaluation was based on post-ITT NIHSS and modified Rankin Scale (mRS) scores. We found that ITT success rate was 75.85 %, with a bleeding rate of 1.55 % and a 90-day mortality rate of 2.01 %. Overall, the data suggest that the ITT therapy was highly successful in AIS patients treated at our hospital.
