Abstract
Background
To evaluate whether topographical characteristics of insular involvement in ischemic stroke
are associated with cardioembolism.
Methods and Findings
A consecutive series of patients hospitalized for ischemic stroke within 7 days of symptom
onset were identified. Based on diffusion-weighted imaging, we included those who had
ischemic lesions in the middle cerebral artery (MCA) territory. Each patient was assigned to
one of two groups based on the presence or absence of insular involvement. The primary
outcome was the frequency of cardioembolism, which was compared based on insular
involvement. Of 1,311 patients with ischemic stroke in the MCA territory, 112 had insular
involvement (8.5%). The frequency of cardioembolism in patients with insular involvement
(52.7%) was significantly higher than that in patients without insular involvement (30.4%,
P < 0.001). Although insular involvement was associated with a severe baseline National
Institutes of Health Stroke Scale score (13 vs. 4), it did not independently affect the 3-month
functional outcome.
Conclusions
In cases of stroke in the MCA territory, involvement of the insular cortex may be associated
with a risk of cardioembolism.
