Insights
Intravenous thrombolysis (IT) showed no significant clinical benefit in cardioembolic (CE) stroke compared to non-cardioembolic (NCE) stroke. Outcomes were similar between groups, suggesting IT may not be specifically beneficial for CE stroke patients.
Area of Science:
- Neurology
- Cardiology
- Emergency Medicine
Background:
- Intravenous thrombolysis (IT) is a critical treatment for acute ischemic stroke.
- Previous studies suggested potential benefits of IT in cardioembolic (CE) stroke due to larger recanalization extent.
Purpose of the Study:
- To assess the clinical efficacy of intravenous thrombolysis (IT) in patients with cardioembolic (CE) stroke compared to non-cardioembolic (NCE) stroke.
Main Methods:
- A cohort of 177 patients undergoing IT was retrospectively analyzed.
- Patients were categorized into CE and NCE groups.
- Clinical outcomes were evaluated using the National Institutes of Health Stroke Scale (NIHSS) and modified Rankin Scale (mRS).
Main Results:
- Mean NIHSS scores at admission, 24 hours, and discharge were similar between CE and NCE groups.
- The reduction in NIHSS from admission to 24 hours and discharge did not significantly differ between the CE and NCE subgroups.
- Modified Rankin Scale scores at discharge and 3 months showed no significant difference between subtypes, though NCE patients trended towards greater independence at 3 months.
Conclusions:
- The study findings do not support a specific benefit of IT in cardioembolic stroke.
- The heterogeneity within the non-cardioembolic (NCE) group might influence outcomes.
- Further research is needed to clarify the role of IT in different stroke etiologies.
Unlabelled:
It was suggested that intravenous thrombolysis (IT) leads to larger extent recanalization in cardioembolic stroke. In this work we assess if this has beneficial clinical traduction.
Method:
We evaluated 177 patients undergoing IT, which were categorized into cardioembolic (CE) and non-cardioembolic (NCE). National Institutes of Health Stroke Scale (NIHSS) and modified Rankin scale were compared.
Results:
The mean age was 67.4 ± 12.01 and 53.8% were male. The mean NIHSS was: 14 (admission), 9 (24 h) and 6 (discharge), similar in subgroups. The difference between NIHSS at admission and 24 hours was 4.17 ± 4.92 (CE: 4.08 ± 4.71; NCE: 4.27 ± 5.17, p=0.900) and at admission and discharge there was an average difference of 6.74 ± 5.58 (CE: 6.97 ± 5.68; NCE: 6.49 ± 5.49, p=0.622). The mRS at discharge and 3 months was not significantly different by subtype, although individuals whose event was NCE are more independent at 3 months.
Conclusion:
Ours findings argue against a specific paper of IT in CE. It can result from heterogeneity of NCE group.
