RESUMO

BACKGROUND: Patients who have undergone catheter ablation for atrial fibrillation (AF) may experience recurrence of this condition. The efficacy of sacubitril-valsartan (S/V) in preventing AF recurrence compared with angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin II receptor blockers (ARBs) is not established. This meta-analysis aimed to establish the best therapeutic choice for preventing AF recurrence after catheter ablation. METHOD: A systematic search of the PubMed, Embase, and Cochrane databases was conducted for randomized controlled trials (RCTs) and observational studies comparing the use of S/V with ACEI/ARB in patients who underwent catheter ablation. Results are presented as mean difference (MD) with 95% confidence interval (CI). Heterogeneity was assessed with the I2 statistic, and outcomes are expressed as relative risk (RR). R software version 4.2.3 was used for the analysis. RESULTS: Three RCTs and one cohort study, comprising 642 patients with 319 patients in the S/V group and 323 in the control group, were included. Follow-up ranged from 6 to 36 months, with mean ages ranging from 58.9 to 65.8 years. A significant reduction in persistent AF occurrence was demonstrated favoring the S/V group (RR: 0.54; 95% CI: [0.41, 0.70]; p = 0.000004; I2: 80%) over the ACEI/ARB group. There was no significant difference in left ventricular ejection fraction with S/V use (MD: 1.23; 95% CI: [-0.12, 2.60]; p = 0.076; I2: 0%) compared with ACEI/ARB. The analysis also showed a significant reduction in left atrial volume index (MD: -5.33; 95% CI: [-8.76, -1.90]; p = 0.002; I2: 57%) in the S/V group compared with the ACEI/ARB group. CONCLUSION: This meta-analysis demonstrated the efficacy of S/V in reducing the incidence of AF in patients undergoing catheter ablation compared with the use of ACEI/ARB. However, more RCTs are needed for a comprehensive evaluation of its efficacy in reducing AF recurrence after catheter ablation in clinical practice.
