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.
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.
