Left atrial strain parameters for predicting new-onset atrial fibrillation: a systematic review and meta-analysis

1

Left atrial strain parameters (LASPs) are evaluated by speckle tracking echocardiography to predict new-onset atrial fibrillation (NOAF).
2

The meta-analysis included 39 studies with 20,681 subjects, revealing significant associations between low LASPs and increased risk of NOAF.
3

PALS, LASr, LAScd, and LASct showed risk ratios indicating that lower values correlate with a higher likelihood of developing NOAF.
4

The summary receiver operating characteristic curve analysis indicated good diagnostic performance for PALS, LASr, and LASct with AUCs of 0.84, 0.84, and 0.78, respectively.
5

This study supports the use of LASPs as diagnostic tools for evaluating and predicting the risk of NOAF in clinical practice.
