Electrocardiographic left atrial abnormalities and risk of incident stroke in hypertensive patients with electrocardiographic left ventricular hypertrophy

摘要

Background: Recent findings in population-based studies suggest that abnormal P wave terminal force in lead V1 (PTFV1), a marker of left atrial abnormalities such as fibrosis, dilatation and elevated filling pressures, is associated with incident ischemic stroke, even in the absence of atrial fibrillation. However, whether PTFV1 predicts incident stroke in hypertensive patients during blood pressure lowering has not been examined.
