Abstract
MACIAS-RUIZ, Rosa et al. Effect of programmed electrical cardioversion of atrial fibrillation on renal function. Rev. Colomb. Cardiol. [online]. 2022, vol.29, n.3, pp.286-294. Epub Sep 01, 2022. ISSN 0120-5633. https://doi.org/10.24875/rccar.m22000158.
Introduction:
Previous studies have linked the presence of atrial fibrillation (AF) with a reduced estimated glomerular filtration rate (eGFR).
Objective:
to compare the evolution of eGFR in patients with persistent AF after elective electrical cardioversion (ECV) based on the existence or not of recurrences, as well as the evolution of various biomarkers.
Materials and methods:
Prospective cohort of patients with persistent AF referred to our center for elective EVC with a 1-year follow-up. The eGFR was obtained using the CKD-EPI formula at baseline and at 3 and 12 months. Biomarkers were measured before ECV and at 12 months.
Results:
92 patients with persistent AF were included, mean age 64 ± 11 years. At one year of follow-up and in all patients, the eGFR decreased from 86.5 [74.6-97.6 to 84.5 [71.7-95.1 ml/min/1.73 m2 (p = 0.002) and creatinine increased from 0.80 [0.72-0.94] mg/dl to 0.83 [0.74-0.97] mg/dl (p = 0.005). The eGFR was reduced at the end of the follow-up, with no statistically significant difference between the patients who had recurrence at 12 months and those who did not. BNP and corin levels improved at 12 months, while galectin-3 did not change, unrelated to eGFR.
Conclusions:
In patients with persistent AF treated with elective ECV, a worsening of eGFR was observed at one year of follow-up. BNP and corin levels improve at one year of follow-up, there were no differences in galectin-3 levels.
