Factors Affecting Management of Acute Ischaemic Stroke with Reference to Intravenous Thrombolysis and Its Impact on Short-term Outcome

Background: Stroke is a major global health concern, ranking second in terms of fatality worldwide, following ischaemic heart disease. However, few stroke patients arrive at the hospital within the optimal time for thrombolysis, and even among those who do, not all receive this therapy. Therefore, the objective of the study was to examine the factors that influence the treatment of acute ischaemic stroke (AIS), particularly with intravenous thrombolysis and to evaluate the short-term outcomes. Methods: This prospective observational study was carried out between August 2019 and August 2021 in the emergency department of a tertiary care hospital. Patients with AIS who were eligible for intravenous thrombolysis within 4.5 hours of the beginning of symptoms were included in the study. Comprehensive assessments, including history, examinations and blood investigations, were conducted. Thrombolytic treatment was administered within the specified time frame, while antiplatelets were given in other cases. Follow-up evaluations were conducted at discharge and 90 days. Results: The age distribution, comorbidities and CT-MRI findings were similar between individuals who received thrombolysis and those who did not. Among the thrombolysis group, 84% had no complications, while 8% experienced intracerebral haemorrhage and 8% had an extension of the infarction. The overall mortality rate was 13.33% for non-thrombolysis patients and 12% for thrombolysis recipients, with no statistically significant difference between the two groups. Conclusion: The results highlight the need for careful consideration when deciding to use thrombolysis for AIS cases. Additionally, they emphasise the importance of actively monitoring and effectively managing any potential treatment complications.
