'Motion-Tracking' MRI Tests Reveal Novel Harbingers of Stroke in People with Common Heart Rhythm Disorder

Stroke is a frequent and dreaded complication of atrial fibrillation. But predicting which of the estimated six million Americans with a-fib are at highest risk has long challenged physicians weighing stroke risk against the serious side effects posed by lifelong therapy with warfarin and other blood thinners.

"Motion-Tracking" MRI Tests Reveal Novel Harbingers of Stroke in People with Common Heart Rhythm Disorder

Researchers performing sophisticated motion studies of heart MRI scans have found that specific altered function in the left atrium of the heart may signal stroke risk in those with atrial fibrillation and, possibly, those without it.
