Remote ischemic conditioning (RIC) is a simple, non-invasive procedure that has been shown to be safe and feasible in multiple smaller clinical trials. Recent large randomized controlled trials have yielded mixed results regarding clinical effect. Patients with severe stroke may experience greater benefit from cerebroprotective interventions, highlighting the need for adjunctive therapies to enhance endovascular therapy (EVT) outcomes. This post hoc analysis of the RESIST trial evaluates the effect of RIC in the subgroup of patients who underwent EVT. Eligible patients were adults (≥ 18 years old), independent in activities of daily living, who had prehospital stroke symptoms with a duration of less than 4 h. They were randomized to RIC or sham. The primary analysis was performed using the entire range ("shift analysis") of the modified Rankin scale (mRS) at 90 days. A total of 737 patients had acute ischemic stroke, and 134 received EVT. The median (IQR) age was 74 (62, 82) years, median NIHSS was 16 (8, 20), and 52 (39%) were female. Median (IQR) overall adherence to RIC/sham was 81% (56, 96). Intravenous thrombolysis (IVT) was initiated in 76 out of the 134 (57%) EVT-treated patients. There was no significant effect of RIC on mRS in EVT-treated patients, OR (95% CI) 1.26 (0.68-2.32). When IVT was given in addition to EVT, RIC was associated with improved functional outcome at 90 days, adjusted OR 2.46 (1.05, 5.78), p = 0.038 but not without adjunctive IVT, aOR 0.57 (0.21-1...
