BACKGROUND: Activation of the renin-angiotensin-aldosterone axis with elevation of inflammatory markers and the resulting fibrosis play a very important role in atrial remodeling in patients with atrial fibrillation (AF), which is associated with post-cardioversion recurrence.
AIM OF THE STUDY: The purpose of the study was to describe the time course of angiotensin II (AngII), aldosterone, and of the amino terminal pro-peptide of type III pro-collagen (PIIINP) following cardioversion, and their association with arrhythmia recurrence.
METHODS: Ninety-nine subjects with long-standing, persistent, non-valvular atrial fibrillation who underwent successful electrical cardioversion were included, with a 6 month follow up. Angiotensin II (AngII), aldosterone and PIIINP concentrations were measured at 0, 1, 7, 30, and 180 d. Two groups were formed for the analysis: continuing sinus rhythm and recurrence of AF.
RESULTS: 53% of the subjects experienced recurrence of AF. Subjects with recurrence had larger left atrial diameters and lower global peak atrial longitudinal strain (8.7 vs. 19.7%; p <0.001), higher levels of AngII (431.85 vs. 257.97 pg/mL; p = 0.003) at 180 d, higher pre-cardioversion levels of aldosterone, (11.42 vs. 5.46 pg/mL; p = 0.048) at 1 d (12.01 vs. 5.05 pg/mL; p = 0.004) and at 180 d (12.66 vs. 7.51 pg/mL; p = 0.011). There were no differences in PIIINP levels between both groups.
CONCLUSIONS: Electrical post-cardioversion recurrence in subjects with long-standing, persistent AF is associated with elevated levels of AngII and aldosterone.
