Night shift work was associated with functional outcomes in acute ischemic stroke patients treated with endovascular thrombectomy
Abstract
Objective: This study aimed to explore the impact of late night shift work on the functional outcomes of patients with acute ischemic stroke (AIS) treated with endovascular thrombectomy (EVT). Methods: Consecutive AIS patients who underwent EVT between June 2019 and June 2021 were enrolled and divided into non-night shift work and night shift work groups based on their occupational histories. The primary outcome was the modified Rankin Scale score defined 3-month functional outcome. The secondary outcomes were 3-month mortality, symptomatic intracerebral hemorrhage (sICH), ICH and early recanalization. Results: A total of 285 patients were enrolled, 35 patients (12.3%) were night shift workers, who were younger (P < 0.001) and had a significantly higher prevalence of smoking (P < 0.001), hyperlipidemia (P = 0.002), coronary heart disease (P = 0.031), and atrial fibrillation (P < 0.001). The 3-month favorable outcomes were achieved in 44.8% and 25.7% of patients in the non-night shift work and night shift work groups, respectively (adjusted odds ratio [OR]: 0.24, 95% CI: 0.10–0.57; adjusted P = 0.001). No difference was found in 3-month mortality (adjusted OR: 0.43; 95% CI: 0.14–1.25, adjusted P = 0.121), rates of ICH (adjusted OR: 0.73; 95% CI: 0.33–1.60; adjusted P = 0.430), sICH (adjusted OR: 0.75; 95% CI: 0.34–1.67; adjusted P = 0.487), or early successful recanalization (adjusted OR: 0.42; 95% CI: 0.12–1.56; adjusted P = 0.197). These results were consistent after PSM analysis. Conclusion: Our findings suggest that late night shift work is significantly associated with unfavorable outcomes in patients with AIS after EVT.
