Patients of AF treated with catheter Ablation at lower risk of HF compared to medical therapy
A recent study published in the Heart Rhythm O2 found the critical aspect of atrial fibrillation (AF) treatment - its impact on heart failure (HF) development. Atrial fibrillation, a common heart rhythm disorder, has long been associated with an increased risk of heart failure. However, the question of whether the choice of treatment affects this risk has remained largely unexplored.
The study aimed to compare the incidence of heart failure among AF patients undergoing treatment with anti-arrhythmic drugs (AAD) versus catheter ablation (CA).
Researchers delved into the Optum Clinformatics database to identify AF patients who had previously used an anti-arrhythmic drug. These patients were then divided into two cohorts: one group received catheter ablation, while the other continued with a different anti-arrhythmic drug prescription. The two cohorts were meticulously matched based on various socio-demographic and clinical factors using a propensity score matching technique. To compare the risk of developing heart failure between the two groups, a Cox regression model was employed. Subgroup analyses were conducted considering factors such as race/ethnicity, gender, AF subtype, and CHA2DS2-VASc score.
