Key result
Left atrial dimension was significantly greater in patients with ischemic stroke compared to controls (3.38 cm vs 3.56 cm; P<0.0001), despite the apparent typo in the abstract's reported values.
Why the study?
Does increased left atrial size associate with ischemic stroke in patients with sinus rhythm and normal left ventricular systolic function?
Case-Control (n=52)
Does increased left atrial size associate with ischemic stroke in patients with sinus rhythm and normal left ventricular systolic function?
Absolute Event Rate: 3.38% vs 3.56%
p-value: p=< 0.0001
Echocardiographic left atrial enlargement is associated with an increased risk of ischemic stroke even in patients with sinus rhythm and normal left ventricular systolic function.
Larger left atrial dimension may mark ischemic stroke risk; leaves open incremental value for prediction beyond established factors.
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.

Hanan Altalhi (2016) conducted a case-control in Ischemic stroke (n=52). Left atrial dimension vs. Control subjects without ischemic stroke was evaluated on Left atrial dimension (p=< 0.0001). Left atrial dimension was significantly greater in patients with ischemic stroke compared to controls (3.38 cm vs 3.56 cm; P<0.0001), despite the apparent typo in the abstract's reported values.
