Stroke is the 3rd leading cause of death in the US. §10% of stroke victims suffer cardiac outcomes due to §coronary artery disease or cardiac derangements §induced by stroke. Damage to the left insula may §cause impairment of cardiac parasympathetic tone §favoring the sympathetic system leading to adverse §cardiac outcomes. §§The author performed a prospective study of §stroke/TIA patients and compared cardiac outcome §between those with left insular stroke and those §with stroke involving other locations. Power §spectral analysis was performed to assess autonomic §tone.§§Left insula stroke was found to be an independent §predictor of the outcomes. The association was even §stronger among patients without symptomatic coronary §artery disease. Power spectral analysis showed that §there was an increase in instability of §parasympathetic tone in patients with left insular §stroke and there was no increase in instability of §sympathetic tone. §§It has been concluded that left insular stroke is §associated with an increased risk of adverse cardiac §outcomes. A possible mechanism is impairment of the §parasympathetic tone favoring the sympathetic §system.
