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.
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.
Kamel et al. (2015) studied this question.
