Abstract

Purpose: To investigate the benefit (90-day mRS score) and rate of major complications (early symptomatic intracranial hemorrhage-SICH) after reperfusion therapy (RT) (including intravenous thrombolysis -IVT and mechanical thrombectomy -MT) in patients over 80 years with acute ischemic stroke (AIS).

Patients and methods: AIS patients aged over 80 admitted to Huizhou Central People's Hospital from September 2018 to 2023 were included in this study. Data on SICH, NIHSS, and mRS were analyzed. A good prognosis was defined as a mRS ≤ 2 or recovery to pre-stroke status at 90 days.

Results: Of 209 patients, 80 received non-RT, 100 received IVT and 29 underwent MT. The non-RT group had the lowest baseline NIHSS while the MT group had the highest (non-RT 6.0 vs IVT 12.0 vs MT 18.0, P <0.001). Higher NIHSS was associated with increased SICH risk (OR 1.083, P=0.032), while RT was not (OR 5.194, P=0.129). The overall SICH rate in the RT group was higher but not significantly different after stratification by stroke severity. Poor prognosis was associated with higher admission NIHSS, stroke due to large artery atherosclerosis (LAA) combined with cardioembolism (CE), and stroke-associated pneumonia (SAP) (OR 0.902, P<0.001; OR 0.297, P=0.029; OR 0.103, P<0.001, respectively). The RT group showed a greater reduction in NIHSS (delta NIHSS) than the non-RT group (non-RT 2.0 vs IVT 4.0 vs MT 6.0, P<0.005). For severe AIS, the IVT group had a better prognosis at 90 days (non-RT 0% vs IVT 38.2%, P=0.039). No 90-day mortality difference was found between groups after stratification.

Conclusion: Stroke severity, rather than RT, is an independent risk factor for SICH in AIS patients over 80. RT in severe stroke patients improves NIHSS at 90 days, suggesting RT is safe and effective in this demographic. Further studies with larger samples are required to confirm these findings.
