Association Between Acute Stroke and COVID-19 Infection among Patients with Acute Stroke

Background Severe acute respiratory syndrome coronavirus 2 (SARS COV 2) infection is associated with multiple neurological complications. Cerebrovascular accidents are considered as one of the common neurological complications associated with corona virus (COVID-19). It may represent the first presentation of the patients of COVID-19 or may occur anytime during the course of the disease. Results This study included 381 patients after the diagnosis of cerebrovascular accident. The mean age of the participants was 57.1 ± 15 years. 53.5% of the participants were males and 46.5% were females. The participants had COVID-19 infection in past 3 months with mean duration was 35.5 ± 18 days. The mean NIHSS among the participants was 10.5 ± 6.2. Small artery stroke was higher among PCR negative patients and controls, while large artery stroke was higher among PCR positive patients. 26% of patients with stroke and confirmed COVID-19 infection developed stroke immediately after COVID-19 infection (within 1 week). Within 1 month from getting infection with COVID-19, 41.7% of patients developed stroke and 32.3% had developed stroke after 1 month of infection with COVID-19. Female gender, older age of the patients and presence of vascular risk factors were associated with increased severity of infection as evidenced by higher NIHSS and more ICU admission among COVID-19 positive patients. Conclusions COVID-19 infection has been associated with both venous and arterial stroke, especially in elderly patients. COVID-19 infection was associated with increased stroke severity as evidenced by higher NIHSS and more ICU admission. Small vessel disease was higher among COVID-19 negative patients, while large artery stroke was higher among positive COVID-19 patients.
