Why the study?
Is ECG-defined left atrial abnormality associated with incident cryptogenic or cardioembolic stroke independently of atrial fibrillation?
Is ECG-defined left atrial abnormality associated with incident cryptogenic or cardioembolic stroke independently of atrial fibrillation?
ECG-defined left atrial abnormality is an independent risk factor for cryptogenic or cardioembolic stroke, suggesting atrial thromboembolism can occur without recognized atrial fibrillation.
May aid cryptogenic stroke risk stratification beyond AF; hypothesis-generating for anticoagulation trials in atrial cardiopathy.
ECG-defined left atrial abnormality was associated with incident cryptogenic or cardioembolic stroke independently of the presence of AF, suggesting atrial thromboembolism may occur without recognized AF.
