Abstrakt:	Background: Carotid artery disease is an important cause of ischemic strokes. Patient selection for urgent carotid interventions (ie, urgent carotid endarterectomy [uCEA] and urgent carotid artery stenting [uCAS]) performed within 2 weeks of an event during the index hospitalization is based primarily on a patient's overall health and risk profile. Identifying high-risk patients remains a challenge. Frailty, a decrease in function related to aging, has emerged as an important factor in the treatment of the elderly population. This study aimed to design a quantitative risk score based on frailty for patients undergoing uCEA and uCAS after an acute stroke. Methods: A total of 307 acute stroke patients treated with uCEA or uCAS were identified from a prospectively maintained database. Frailty scores were calculated using the Hospital Frailty Risk Index based on International Classificiation of Diseases, 10th edition, codes. Stroke-specific risk categories were created based on the incidence of stroke, death, and myocardial infarction (MI) associated with frailty scores. Primary end points included 30-day stroke, death, and MI, and the secondary end point was discharge modified Rankin scale (mRS). Statistical analyses were performed using SAS software. Results: The average age was 65.9 years; hypertension, a history of tobacco use, and hyperlipidemia were the most common comorbidities. The median Hospital Frailty Risk Score was 27; the majority of patients in this study were in the intermediate and high risk frailty groups (50.5% and 41.7%, respectively). uCAS patients had a higher median presenting National Institutes of Health Stroke Scale (NIHSS) (8 vs 2; P < .001) and shorter median time to intervention compared with uCEA patients (1 day vs 3 days; P ≤ .001). The 30-day composite stroke, death, and MI rate was 8.1%, with higher rates observed in patients with frailty scores of >30 (11.7%) and uCAS (12.2%). Hemorrhagic conversion and death were more common in uCAS patients. Functional independence (mRS 0-2) was observed in uCEA patients after minor stroke and in uCAS patients after minor or moderate stroke. Patients with high-risk frailty score (>30) presenting with a moderate stroke were more likely to be functionally dependent (mRS > 2) on discharge (67 vs 41.3%; P < .001). Conclusions: Frailty is a valuable prognosticative tool for clinical outcomes in patients undergoing urgent carotid interventions after an acute stroke. Higher frailty scores were associated with increased stroke, death, and MI rates. Frailty also influenced functional dependence at discharge, particularly in patients with moderate stroke. These findings highlight the importance of considering frailty in the decision-making process for carotid interventions. Further research is needed to validate these findings and explore interventions to mitigate the impact of frailty on outcomes. Competing Interests: Disclosures None.
