Increased left atrial (L A) size associated with poor cardiovascular outcome such as development of heart failure, atrial fibrillation (AF) and stroke in the elderly. Objective: The present study was conducted to reevaluate the relationship between la size and stroke in subjects of all ages, not just the elderly who presented with preserved left ventricular systolic function (lvsf) and sinus rhythm (sr). Patients and Methods: This is case control study of 52 patients admitted to the hospital 26 with diagnosis of ischemic stroke (case subject), and 26 patients without ischemic stroke were included as (control subject). The diagnosis of Cerebral infarction was confirmed by a new computer Tomography of Brain All participant underwent the standard examination and testing as well as Echocardiography (measurement of left atrial dimension, Ejection Fraction,Mitral inflow, LV mass), patients with valvular heart disease, atrial fibrillation or coronary disease were excluded. Result: The mean age was 69 ± 18 years in the stroke group and 66 ± 17 years in control group. The LA dimension of stroke group (3.38 ± 0.50 cm) was significantly greater than that of the control group (3.56 ± 0.44cm); P< 0.0001) E&A Velocity showed no significant relation with Stroke (p=NS) Left ventricular mass, left ventricular mass / height and left ventricular mass index were significantly related to stroke (p<0.0001, p= 0.001, p = 0.001, respectively). Conclusion: Echocardiographic left atrial enlargement has prognostic value in identifying a subset of persons at increased risk of stroke.
