The risk of ischemic stroke and associated left atrial strain in elderly individuals

  • A cohort study investigating the cardiovascular factors associated with subclinical cerebrovascular disease. Left atrial strain (LAε) and left atrial strain rate (LASR) were assessed by speckle-tracking echocardiography.
  • The lowest positive longitudinal LAε (compared to other quintiles) and negative longitudinal LASR were associated with incident ischemic stroke, independent of left ventricular global longitudinal strain and incident atrial fibrillation.
  • Authors concluded that speckle-tracking echocardiography assessment of LAε and LASR may improve stroke risk stratification.
