Key result
Decreased negative left atrial longitudinal strain rate assessed by speckle tracking echocardiography was independently associated with paroxysmal atrial fibrillation (OR 8.56; 95% CI 1.14-64.02; P=0.036).
Why the study?
Is left atrial strain and strain rate assessed by speckle tracking echocardiography associated with paroxysmal atrial fibrillation in patients with episodic palpitation?
Population

May support LA strain rate evaluation in palpitations; leaves open prospective validation before clinical adoption.

Is left atrial strain and strain rate assessed by speckle tracking echocardiography associated with paroxysmal atrial fibrillation in patients with episodic palpitation?
Effect estimate: OR 8.56 (95% CI 1.14-64.02)
p-value: p=0.036
Decreased negative left atrial strain rate measured by speckle tracking echocardiography is independently associated with paroxysmal atrial fibrillation.
Tsai et al. (2009) conducted an observational in Paroxysmal atrial fibrillation (n=52). Left atrial longitudinal strain (LAS) and strain rate (LASR) measured by speckle tracking echocardiography vs. Patients without paroxysmal atrial fibrillation was evaluated on Paroxysmal atrial fibrillation (OR 8.56, 95% CI 1.14-64.02, p=0.036). Decreased negative left atrial longitudinal strain rate assessed by speckle tracking echocardiography was independently associated with paroxysmal atrial fibrillation (OR 8.56; 95% CI 1.14-64.02; P=0.036).
