Abstract

Objectives: Chronic inflammation of the gastrointestinal tract is a hallmark of inflammatory bowel disease (IBD). This increased inflammation is thought to induce a hypercoagulable state that increases the risk for stroke. However, few studies have examined the association between IBD and acute ischemic stroke (AIS). Thus, this study aims to investigate the incidence, treatments, complications, and outcomes of AIS in patients with IBD. Materials & Methods: ICD-9-CM and ICD-10-CM codes were used to query the National Inpatient Sample for AIS and IBD diagnosis. Baseline demographics, clinical characteristics, complications, treatments, and outcomes were assessed through descriptive statistics, multivariate regression, and propensity score matching (PSM) analysis. Acute stroke severity was assessed using the National Institute of Heath's Stroke Severity Score (SSS) as a template. Results: 1,609,817 patients were diagnosed with AIS between 2010 through 2019. 7468 (0.46%) had concomitant diagnoses of IBD. AIS patients with IBS were younger, more likely to be white and female, but less likely to be obese. Although IBD patients had comparable stroke severities (p  =  0.64) to their non-IBS counterparts, they received stroke intervention at statistically different rates than their non-IBD counterparts. Additionally, IBD patients had higher rates of in-hospital complications (p < 0.01) and longer lengths of stay (LOS) (p < 0.01). Conclusions: IBD patients develop AIS at a younger age with similar rates of stroke severity to their non-IBD counterparts, but receive higher rates of tissue plasminogen activator administration and decreased rates of mechanical thrombectomy. Our research shows that patients with IBD are at risk for AIS at an earlier age and are more likely to have complications. This underlies a connection between IBD and a hypercoagulable state that could predispose patients to AIS.
