Key result
Left ventricular filling pressure assessed by E/A ratio (OR 0.550) and E/e' ratio (OR 0.871) independently predicted sinus rhythm maintenance at 12 months after electrical cardioversion.
Why the study?
To assess whether echocardiographic measurements of left atrial morphology and function could predict sinus rhythm maintenance after electrical cardioversion in patients with persistent AF and normal function or mild dysfunction of the LV.
Do echocardiographic measures of left ventricular filling pressure (E/A and E/e' ratios) predict maintenance of sinus rhythm at 12 months in patients with persistent atrial fibrillation after successful electrical cardioversion?
Cohort (n=117)
No

Odds Ratio: 0.55 (95% CI 0.341–0.886)
p-value: p=0.014
Echocardiographic assessment of left ventricular filling pressure using E/A and E/e' ratios can independently predict the recurrence of atrial fibrillation 12 months after successful electrical cardioversion.
No takes yet. Share an insight, caveat, or question.
Filling pressure indices may aid post-cardioversion rhythm prediction; hypothesis-generating and requires prospective validation before practice change.
Wałek et al. (2019) conducted a cohort in Persistent atrial fibrillation (n=117). Echocardiographic E/A and E/e' ratios was evaluated on Sinus rhythm maintenance at 12 months (OR 0.550, 95% CI 0.341-0.886, p=0.014). Left ventricular filling pressure assessed by E/A ratio (OR 0.550) and E/e' ratio (OR 0.871) independently predicted sinus rhythm maintenance at 12 months after electrical cardioversion.
