ABSTRACT
BACKGROUND:
The safety and efficacy of intravenous thrombolysis (IVT) in acute ischemic stroke patients with large vessel occlusions and mild neurological deficits are controversial.METHODS:
Data of stroke patients presenting with mild initial stroke, which was defined as the National Institutes of Health Stroke Scale score (NIHSS) ≤5 and large vessel occlusion, were extracted from a large provincewide stroke registry.RESULTS:
A total of 619 IVT and 2170 non-IVT patients were identified in this study. IVT patients had higher rates of favorable functional outcome Modified Rankin Scale(mRS) ≤1 (74.6% vs. 70.6%; P =0.047), lower mRS scores (1 vs. 1, P =0.001), and higher NIHSS score decreased (1 vs. 0, P <0.001) at discharge compared with the non-IVT patients. The rates were similar in symptomatic intracranial hemorrhage (2.1% vs. 2.0%, P =0.853), severe systemic bleeding (0.8% vs. 0.6%, P =0.474), and mortality at discharge (0.2% vs. 0.2%, P =0.906) between the 2 groups. A multiple Logistic regression model found that age above 80 years [adjusted OR (aOR) 2.056 (95% CI, 1.125 to 3.756)], history of stroke [aOR 1.577 (95% CI, 1.303 to 1.910)], hyperlipidemia [aOR 2.156 (95% CI, 1.059 to 4.388)], high admission NIHSS score [aOR 1.564 (95% CI, 1.473 to 1.611)], and non-IVT [aOR 1.667 (95% CI, 1.337 to 2.077)] were independent risk factors for mRS >1.CONCLUSIONS:
IVT administration is safe and effective in eligible acute ischemic stroke patients. Age above 80 years, with a history of stroke and hyperlipidemia, high admission NIHSS score, and non-IVT were independent risk factors for mRS >1 at discharge in these patients.
