The Effects of COVID-19 on Patients with Acute Ischemic and Hemorrhagic Stroke.

OBJECTIVE

The objective of this study was to evaluate how COVID-19 affects patients with acute ischemic or hemorrhagic stroke outcome.

MATERIALS AND METHODS

This retrospective study was performed on adult patients (> 18 years old) with stroke (ischemic or hemorrhagic) who were admitted to hospital with or without COVID-19. The primary outcome was stroke-related disability, which was measured by mRS at baseline and discharge. Hospital duration, intensive care unit (ICU) admission, and mortality were considered the secondary outcomes.

RESULTS

From February 2019 until August 2020, we recruited and analyzed 151 patients, 42 of whom had COVID-19 based on RT-PCR tests or lung CT scan findings. COVID-19 positive patients had higher baseline and final mRS scores than the control group (4.46 ± 0.67 vs 4.79 ± 0.61, P: 0.001, 3.83 ± 1.22 vs 4.46 ± 0.67, P: 0.001). Moreover, stroke patients with COVID-19 experienced a more severe disease and required a higher rate of ICU admission (17 vs 0, P:0.001) and longer hospitalization compared to those without COVID-19 (8.50 ± 7.86 vs 7.5 ± 11.20, P: 0.021). Also, mortality was higher in the COVID-19 group (19 vs 13, P:0.001). There was not any significant differences between the two groups in terms of the involvement of cerebral arteries and type of stroke. Male sex, COVID-19, and ICU admission were the main independent risk factors for death.

CONCLUSION

The results of the study showed stroke patients (ischemic or hemorrhagic) with COVID-19 can have more disabilities and incur more hospital complications and mortality than non-COVID-19 patients.
