Estimation of the possibility for left ventricular remodelling after restoration of the sinus rhythm in patients with persistent form of atrialfibrillation

Abstract

Atrial fibrillation is one of the most urgent rhythm disturbances leading to permanent disability of the population. Therefore, the aim of this study was to investigate the possibility of left ventricular remodelling after restoration of sinus rhythm. The results of treatment in 821 patients were analyzed, each of them was assigned to one of 4 groups depending on the tactics of surgical intervention: group 1 — electrical cardioversion was performed, group 2 — pacemaker implantation (DDD) and pharmacological cardioversion; 3rd group — electrical cardioversion and pacemaker implantation; and the 4th group — RFA was performed. After the treatment, a decrease in EDV was revealed by 18.7% in the 1st group, 13.7% in the 2nd group, 19.65% in the 3rd group and 11.3% in the 4th group. An increase in the SD was observed: by 14% in the 1st group, 5.6% in the 2nd group, 10.9% in the 3rd group and by 3.65% in the 4th group, as well as an increase in EF by 48% in the 1st group, 17.5% in group 2, 29.76% in group 3 and 4.5% in group 4. Thus, left ventricular remodelling is feasible after restoration of sinus rhythm after persistent atrial fibrillation.
