title="Kardiochirurgia dorosłych Long-term heart remodelling after surgical ablation for atrial fibrillation \– 4-year long changes of left atrial transport function and N-terminated brain natriuretic propeptide (NT-proBNP)",
abstract="  Background:  Long-term effectiveness of surgical atrial fibrillation (AF) ablation is high. Still few data on long-term atrial remodelling supporting transport function and heart failure reduction are available.    Aim:  Aim was to assess long-term changes of left atrium ejection fraction (LAEF) and NT-proBNP level in 4-year long follow-up after ablation.    Material and Methods:  84 patients (mean age: 64.4\±9.8 years) who underwent concomitant surgical ablation AF were included. At 3, 6, 12, 24, 48 months LAEF, NT-proBNP serum parameters and 24-hour Holter ECG were evaluated. If any electrocardiographically confirmed incidence of AF occurred at any time point the patient was qualified to the AF group.    Results:  64 (76%) patients remained in SR during the observation period. Average LAEF was higher in SR than in AF patients, respectively: 31.6 (\±10.6) vs. 24.6 (\±7.2) %, p=0.007. In the AF group higher NT-proBNP levels were recorded after 24 months (782\±471 vs. 357.6\±319 pg/ml in the SR group; p=0.006) and 48 months (1531\±650 vs. 456.6\±182 pg/dl in SR patients; p=0.03). Between SR and AF patients there was no significant difference in preoperative left atrium diameter (respectively, 55\±11 vs. 59\±16 mm; p=0.2) and arrhythmia duration (respectively, 5.1\±5.4 vs. 4.49\±3.86 years; p=0.6).    Conclusions:  Long-term stable sinus rhythm maintenance after surgical ablation is related to significantly better LAEF and lower NT-proBNP level in comparison to patients with arrhythmia recurrence.",
