Abstract
INTRODUCTION: The clinical factors predisposing to ischemic stroke in reversible cerebral vasoconstriction syndrome (RCVS) are unclear. In this observational cross-sectional study, we aimed to evaluate the risk factors and clinical outcomes associated with the development of ischemic stroke in patients with RCVS. METHODS: We utilized the Nationwide Readmissions Database 2016-2017 to identify all hospitalizations with RCVS, with or without acute ischemic stroke. Independent predictors of and clinical outcomes associated with ischemic stroke were analyzed using logistic regression. RESULTS: Among 1065 hospitalizations for RCVS (mean ± SD age 49.0 ± 16.7 years, female 69.7%), 267 (25.1%) had ischemic stroke. Patients with ischemic stroke were more likely to have hypertension (OR 2.33, 95% CI 1.51-3.60), diabetes (OR 1.81, 95% CI 1.11-2.98), and tobacco use (OR 1.64, 95% CI 1.16-2.33) and were less likely to have a history of migraine (OR 0.56, 95% CI 0.35-0.90). Ischemic stroke was associated with higher odds of cerebral edema (OR 3.15, 95% CI 1.31-7.57) and respiratory failure (OR 2.39, 95% CI 1.28-4.44). Patients with ischemic stroke also had longer hospital stay by a mean duration of 6.7 days, P < 0.001, higher hospital charges by a mean of $72,961, P < 0.001, and a higher likelihood of not being discharged to home (OR 3.57, 95% CI 2.39-5.33). They had higher in-hospital mortality rate; however, the difference was not statistically significant. CONCLUSION: Ischemic stroke affects nearly 25% of patients with RCVS and is associated with adverse clinical outcomes. RCVS patients with cerebrovascular risk factors might have a higher predisposition for developing ischemic lesions during the disease process.
