Right insular infarction is associated with increased mortality in patients with ischemic stroke.
Patients with insular infarction had reduced cumulative survival compared to patients with noninsular infarction (90% vs 99%; P<.001).
Patients with right insular infarction had higher lesion volumes (median, 9.1 mL vs 2.8 mL; P=.001) and National Institutes of Health Stroke Scale scores (median, 6.5 vs 4; P=.027) than patients with left insular stroke.
Right insular infarction was associated with increased mortality in multivariate analysis (HR, 2.60; 95% CI, 1.26-5.36; P=.010).
