Long‐Term Outcome of Catheter Ablation in Atrial Fibrillation Patients with Coexistent Metabolic Syndrome and Obstructive Sleep Apnea: Impact of Repeat Procedures versus Lifestyle Changes

Abstract

MS and OSA have additive negative effect on arrhythmia recurrence following single procedure. Repeat ablation or compliant LSM increase freedom from recurrent AF.

EHRA/HRS/APHRS/SOLAECE expert consensus on atrial cardiomyopathies: definition, characterization, and clinical implication

“…470,474 Metabolic syndrome and obesity A number of studies have evaluated the impact of the metabolic syndrome on catheter ablation outcomes in atrial fibrillation patients. [475][476][477][478][479][480] Although the data are mixed, the weight of studies and a systematic review 477 suggest a higher risk of AF recurrence. In the ARREST AF study, patients with BMI over 27 undergoing AF ablation had a much lower risk of recurrence if weight loss was achieved and maintained.…”

Obstructive Sleep Apnea Treatment and Atrial Fibrillation: A Need for Definitive Evidence

“…The impact of OSA treatment has been extended to the ablation context and results remain consistent with non‐ablation studies. Fein et al . prospectively evaluated a cohort of 62 patients with OSA having pulmonary vein isolation .…”

Treatment of Atrial Fibrillation: Should We Advocate Life‐Style Changes or Ablation Strategies to Maintain Sinus Rhythm? Boot Camp for Atrial Fibrillation

“…In this issue of the Journal , Mohanty et al . report on the impact of life‐style changes on the long‐term outcome of ablation of AF. Among 1,257 AF patients who underwent an initial catheter ablation procedure, the metabolic syndrome and obstructive sleep apnea were both present in 10%, while neither of these were present in 47%, and the remaining 43% had either of these clinical characteristics.…”
