decade3d/iStock/Thinkstock(NEW YORK) -- Researchers are looking into whether the volume of a person's left atria may be correlated in some way with strokes.

According to a study published in the Journal of the American Heart Association, scientists looked at 169 patients with a regular heart rhythm and a history of atrial fibrillation. Those patients underwent a cardiac MRI before undergoing a procedure that would prevent their heart rhythms from becoming irregular again.

Those patients with a history of stroke, researchers found, had left atria that were larger in volume, but did not pump as well. The left atrium is one of the chambers of the heart where clots are known to form.

It was not determined definitively whether the measurements in patients' left atria could in any way predict future strokes. The measurements simply correlated to past strokes.

Nonetheless, researchers hope that future studies could examine whether similar tests could be done to predict or help detect risk of future strokes.
