we analyzed and cross-tabulated 18 clinical characteristics and found four to be significantly associated with a cardioembolic mechanism : stroke with onset during activity and peak deficit at onset ( p less than 0.008 ) , previous infarct in a different vascular territory ( p less than 0.01 ) , previous transient ischemic attack in a different vascular territory ( p less than 0.01 ) , and transient ischemic attack lasting greater than 1 hour ( p less than 0.02 ) .
