D-PO04-235 - Impact Of The Preoperative Nutrition Status On Arrhythmia Recurrence After Catheter Ablation For Atrial Fibrillation (ID 1247)


Background: Nutrition status of the patients who undergo catheter ablation (CA) for atrial fibrillation (AF) varies. Its impact on the recurrence after CA is unclear. The Geriatric nutritional risk index (GNRI) is a simple nutritional assessment tool and is easily calculated from the serum albumin and body mass index (BMI).
Objective: We sought to evaluate the relationship between nutrition status and arrhythmia recurrence.
Methods: We retrospectively enrolled 567 consecutive patients (median 65years) who underwent their first CA for AF and nutrition states was evaluated. The preoperative GNRI was calculated as following: 14.89×serum albumin (g/dL)+41.7×BMI/22.
Results: GNRI-based no-nutritional risk (GNRI≥98) and GNRI-based nutritional risk (GNRI<98) were found in 89.1% and 10.9%. During a median follow-up of 272 days, 75patients had arrhythmia recurrence. On a Log-rank test, no-risk patients were significantly lower arrhythmia recurrence (p=0.002). On a multivariable COX-proportional hazard analysis, lower GNRI independently predicted arrhythmia recurrence (hazard ratio: 2.29, 95% confidence interval: 1.24-4.21, p=0.008).
Conclusion: Preoperative malnutrition status was significantly associated with increased arrhythmia recurrence of patients who underwent CA.
