ABSTRACT
PURPOSE:
Left ventricular (LV) filling pressure affects atrial fibrillation (AF) recurrence. We investigated the relationship between diastolic dysfunction and AF recurrence after cardioversion, and whether LV filling pressure was predictive of AF recurrence. MATERIALS ANDMETHODS:
Sixty-six patients (mean 58+/-12 years) with newly diagnosed persistent AF were retrospectively enrolled. We excluded patients with left atrial (LA) diameters larger than 50 mm, thereby isolating the effect of LV filling pressure. We evaluated the differences between the patients with (group 1) and without AF recurrence (group 2).RESULTS:
Group 1 showed increased LA volume index (LAVI) and E/e' compared to group 2 (p9.15) compared with patients with lower LV filling pressure (E/e'< or =9.15) (log rank p=0.008). Cox regression analysis revealed that E/e' [hazards ratio (HR) 1.100, 95% CI 1.017-1.190] and LAVI (HR 1.042, 95% CI 1.002-1.084) were independent predictors for AF recurrence after cardioversion.CONCLUSION:
LV filling pressure predicts the risk of AF recurrence in persistent AF patients after cardioversion.Key words
