Why the study?
Does ECG-defined left atrial abnormality associate with subsequent nonlacunar ischemic stroke?
Does ECG-defined left atrial abnormality associate with subsequent nonlacunar ischemic stroke?
ECG-defined left atrial abnormality is associated with nonlacunar ischemic stroke, suggesting that underlying atrial cardiopathy may cause thromboembolism even without recognized atrial fibrillation.
Supports atrial cardiopathy evaluation in cryptogenic stroke; hypothesis-generating and should not yet change practice.
We found an association between ECG-defined left atrial abnormality and subsequent nonlacunar ischemic stroke. Our findings suggest that an underlying atrial cardiopathy may cause left atrial thromboembolism in the absence of recognized AF.
