Background: Coronavirus Disease 19 (COVID-19) can cause thromboticcomplications, one of them is ischemic stroke. Stroke is one of the main cause of disability. Age has been shown to be associated with the outcome of patients with acute ischemic stroke (AIS). The aim of this study is to prove the correlation between age and clinical outcome as measured by National Institutes of Health Stroke Scale(NIHSS) in acute thrombotic stroke with COVID-19. Methods: This study usea cross sectional design. The sample in this study was acute thrombotic stroke patients with COVID-19 from March 2020 to May 2021 at the Emergency and Isolation Ward at Dr.Soetomo General Hospital Surabaya. Age and NIHSS datawere taken from medical records when the patient first admitted. Results:We collected 21 subjects consisting of 12 males and 9 females. The mean age of the subjects was 57.62 ± 10.05, with the youngest age was 37 years old and the oldest was 78 years old. The range of NIHSS in this study was 1-33. We found a positive correlation, with moderate correlation strength, between the age variable and the NIHSS which was statistically significant (r=0.483; p=0.026). Conclusion: There is a positive correlation between age and clinical outcomes as measured by NIHSS in acute thrombotic stroke patients with COVID-19.
