Key result
Left atrial longitudinal strain was significantly lower in dilated cardiomyopathy patients with atrial fibrillation compared to those with sinus rhythm (7.44% vs 15.82%; p<0.001).
Why the study?
To assess left atrial longitudinal strain and its role in predicting atrial fibrillation occurrence in patients with dilated cardiomyopathy and LVEF under 40% using speckle tracking echocardiography.
Does left atrial longitudinal strain (PALS) measured by 2D STE correlate with the occurrence of atrial fibrillation in patients with dilated cardiomyopathy and LVEF < 40%?
Cross-Sectional (n=100)
Does left atrial longitudinal strain (PALS) measured by 2D STE correlate with the occurrence of atrial fibrillation in patients with dilated cardiomyopathy and LVEF < 40%?
Left atrial longitudinal strain is significantly reduced in DCM patients with atrial fibrillation, and a cut-off of <11.1% accurately distinguishes them from those in sinus rhythm.
The study aimed to asses left atrial longitudinal strain (PALS)furthermore, its job in anticipating atrial fibrillation (AF) event in patients with expanded cardiomyopathy (DCM) with LVEF under 40% by utilizing dot following echocardiography (STE). in this examination we arbitrarily doled out 100 Egyptian patients with enlarged cardiomyopathy who were additionally ordered into two gatherings: SR gathering, 50 patients with sinus cadence and AF gathering, 50 patients with constant AF. Left atrial longitudinal strain (PALS) was estimated utilizing 2D STE. Left atrial longitudinal strain (PALS) values were altogether lower in AF bunch than in SR gathering (7.44 ±1.49% versus 15.82 ±3.15%; p <0.001). ROC examination showed that PALS under 11.1% (AUC 0.981; 95% CI 0.958–1.000; p < 0.0001) recognize SR from AF patients with DCM. End: In patients with DCM and atrial fibrillation the left atrial longitudinal strain (PALS) values are altogether lower than in patients with AF than the individuals who had saved sinus cadence, PALS cut-off worth <11.1% was appeared to have the best demonstrative exactness in foreseeing event atrial fibrillation in DCM patients and LVEF < 40%.

Elenin et al. (2020) conducted a cross-sectional in Dilated cardiomyopathy with LVEF < 40% (n=100). Chronic atrial fibrillation vs. Sinus rhythm was evaluated on Left atrial longitudinal strain (PALS) (p=<0.001). Left atrial longitudinal strain was significantly lower in dilated cardiomyopathy patients with atrial fibrillation compared to those with sinus rhythm (7.44% vs 15.82%; p<0.001).
