Predictive value of plasma Nt-proBNP and body mass index for recurrence of atrial fibrillation after cardioversion

Clinical significance and levels of blood brain natriuretic peptides in patients with persistent atrial fibrillation before and after catheter ablation

“…BNP secretion is closely correlated with the volume and pressure load of heart chambers (Beck-da-Silva et al, 2004;Date et al, 2006;Wozakowska-Kaplon and Opolski, 2010;Tang et al, 2011;Barassi et al, 2012;Govindan et al, 2012). In the successful ablation group, BNP levels significantly decreased 2 h after surgery (P < 0.01) and declined even further after three months (P < 0.01), which is consistent with the results in the literature (Marsiliani et al, 2010;Deftereos et al, 2011;Freynhofer et al, 2011;Higa et al, 2011;Kawabata et al, 2011;Ruggiero et al, 2011;Psychari et al, 2011). After sinus rhythm was restored, the atrium exhibited effective contractions, its auxiliary pump function recovered, hemodynamic rhythm improved, and poor mechanical and volumetric stimulations to atrial cells decreased or disappeared.…”

N-Terminal Pro-Brain Natriuretic Peptide Shows Diagnostic Accuracy for Detecting Atrial Fibrillation in Cryptogenic Stroke Patients

“…One report evaluated NT‐proBNP as a predictor of AF in patients with stroke in sinus rhythm in general and found that it had a reasonable accuracy for this diagnosis (AUC 0·638; 95% CI 0·531–0·744). Differences between this study and ours may explain the dissimilar result: In our study, we evaluated the accuracy of NT‐proBNP in diagnosing AF in patients with cryptogenic stroke, while the study by Wachter et al .…”

Relationship between Brain Natriuretic Peptides and Recurrence of Atrial Fibrillation after Successful Direct Current Cardioversion: A Meta‐Analysis

“…In four of these studies, the requested data were not available and these studies were excluded from further analyses. Finally, 18 observational studies were included in our systematic review …”

“…Evidence from several observational studies supports an association between BNP or N‐terminal (NT)‐proBNP levels before DCCV and the risk of AF recurrence; however, other studies have failed to observe a relationship . In fact, in three of the most recent studies, a statistically significant association between baseline BNP or NT‐proBNP levels and SR maintenance was not observed .…”
