Abstract Funding Acknowledgements Type of funding sources: None. Background. Knowledge about the association between symptoms and rhythm status (symptom-rhythm correlation) has potential clinical implications as it may identify patients with atrial fibrillation (AF) who profit from rhythm control in regard to reduction in symptom burden and improvement in quality of life. However, standardized strategies to assess symptom-rhythm correlation in AF patients are currently not available. Purpose. This study aimed to assess symptom-rhythm correlation in patients with persistent AF using electrical cardioversion (ECV) as a diagnostic probe. Methods. We used ECV to examine symptom-rhythm correlation in 81 patients with persistent AF. The presence of self-reported symptoms before ECV and at the first outpatient AF clinic follow-up visit (within 1-month) was assessed to determine the prevalence of a symptom-rhythm correlation (defined as self-reported symptoms present during AF and absent in sinus rhythm or absent in AF and yet relief during sinus rhythm). The symptom-rhythm correlation was absent in patients with symptoms before ECV who remained symptomatic during sinus or in patients with symptoms prior to ECV and without symptoms in AF after ECV. Asymptomatic patients before ECV with or without symptoms in AF or sinus rhythm afterwards had no symptom-rhythm correlation as well. The symptom-rhythm correlation was unevaluable in patients who were symptomatic in AF before ECV and at the first outpatient AF clinic follow-up visit. In addition, predominant self-reported symptoms (symptoms with highest self-reported symptom burden) were assessed to evaluate the symptom patterns around ECV. Intra-individually variable symptom patterns were defined as changes in predominant self-reported symptoms within patients around ECV. Results. Symptom-rhythm correlation was assessed in all patients. Only in 18 patients (22%), a symptom-rhythm correlation could be documented. Twenty-eight patients (35%) did not show any symptom-rhythm correlation and 35 patients (43%) had an unevaluable symptom-rhythm correlation as these patients were in symptomatic AF both at baseline and at the first outpatient AF clinic follow-up visit. Importantly, self-reported symptom patterns around ECV were intra-individually variable in 10 patients (12%) without symptom-rhythm correlation (of which 9 patients (11%) had AF recurrence) and in 2 patients (2%) with an unevaluable symptom-rhythm correlation. Conclusions. In patients with persistent AF, the prevalence of a symptom-rhythm correlation around ECV is low, but ECV often changes symptom pattern. Further studies are warranted to identify more optimal strategies to assess symptom-rhythm correlation in patients with persistent AF. Abstract Figure. Symptom-rhythm correlation and patterns

Atrial fibrillation (AF) despite the absence of heart failure is related to increased levels of natriuretic peptides (NPs). NPs have not been widely investigated in relation to left atrium (LA) function after sinus rhythm (SR) restoration and duration of AF. The aim of the study was to determine the changes of NPs levels and to define their relation with LA phasic function after electrical cardioversion (ECV). Methods. The study included 48 persistent AF patients with restored SR after ECV. NT-proANP and NT-proBNP were measured for all patients before the ECV. LA phasic function (reservoir, conduit, and pump phases) was assessed using echocardiographic volumetric analysis within the first 24 hours after ECV. Patients were repeatedly tested after 1 month in case of SR maintenance. Results. After 1 month, SR was maintained in 26 (54%) patients. For those patients, NT-proBNP decreased significantly (p=0.0001), whereas NT-proANP tended to decrease (p=0.13). Following 1 month after SR restoration, LA indexed volume decreased (p=0.0001) and all phases of LA function improved (p=<0.01). Patients with AF duration < 3 months had lower NT-proANP compared to patients with AF duration from 6 to 12 months (p = 0.005). Higher NT-proANP concentration before ECV was associated with lower LA reservoir function during the first day after SR restoration (R=-0.456, p=0.005), whereas higher NT-proBNP concentration after 1 month in SR was significantly related to lower LA reservoir function (R=-0.429, p=0.047). Conclusions. LA indexed volume, all phases of LA function, and NT-proBNP levels improved significantly following 1 month of SR restoration. Preliminary results suggest that higher baseline NT-proANP levels and higher NT-proBNP for patients with maintained SR for 1 month are related to lower LA reservoir function. The longer duration of persistent AF is associated with higher NT-proANP concentration.

Electrical Cardioversion

In the present retrospective cohort study, we have evaluated the missed or delayed atrial mechanical recovery in a population of patients with persistent or long-lasting persistent AF who achieved restoration of sinus rhythm on the ECG by electrical cardioversion (ECV).  The endpoint of our   study was   the failure to recover the normal mechanics of the left atrium.  Inclusion criterion was the persistent or long-lasting persistent atrial fibrillation successfully treated by means of    ECV , provided that  a pertinent documentation  was made available, comprising ECG, conventional 2D echo-color-Doppler and   speckle tracking echocardiography(STE)  evaluation, with also a STE assessment  of the atria at the days 1, 30 and 90  from the ECV freely available within  the clinical record  of the patient. Out of a total of 80 patients with persistent or long-standing persistent AF, retrospectively enrolled, as many as  22.5% of them did not achieve the normalization of their  atrial STE profile, even though they had been converted to sinus rhythm on the ECG by means of ECV.  The building of ROC curves allowed us to establish that early measurements of global atrial strain could serve to predict  both the risk of failure to recover the atrial mechanical function and the one of AF relapses over a 12 month follow-up. The   values of 18% and 17% were also calculated  to serve as cut off values, respectively,  for the risk  of atrial mechanical dysfunction and for the risk of AF  relapses over a 12 month follow-up. Failure to recover the atrial reservoir function can accompany a restoration of sinus rhythm on the ECG in patients with long-standing persistent AF. In this case, a serial STE evaluation could be useful to evaluate the atrial hypofunction over time.
