National Trends of Acute Pericarditis Post Atrial Fibrillation Ablation.

Atrial fibrillation ablationincreased over the last two decades given its high success rate. However, the trend of inpatient adverse outcomes is limited. The aim of this study to examine the frequency and predictors of acute pericarditis resulting from catheter ablation METHODS: Using National Inpatient Sample, we identified all patients who underwent AF ablation. Univariate and multivariate logistic regression were performed for the primary outcome of in-hospital acute pericarditis post AF ablation.Variance-weighted regression has been used to test for linear and curvilinear trends in disease characteristics and outcomes over time RESULTS: From 2002 to 2014, our study included 122,993patients, acute pericarditis was found in 984 (0.8%) of patients who underwent AF ablation. The trend ofacute pericarditis showed inconsistent fluctuation leaning toward reduction over the years. Multivariate analysis showed that patients of female gender are at a 40% higher risk of acute pericarditis post ablation compared to males. Additionally, obese patients have a 40% higher risk of developing acute pericarditis compared to Patients who have BMI <30. Furthermore, anemia and rheumatoid arthritis have the odds ratio(OR:2.63; 95% [CI] 2.04 to 3.39) and (OR:1.64; 95% [CI] 1.08 to 2.48).Post AF ablation, In-hospital acute pericarditisshowed inconsistent fluctuation leaning toward reduction. Female gender and obesity are higher risk for developing acute pericarditis post AF ablations. Proper evaluation might alter those complications.
