Body Roundness Index as a Predictor of Electrical Cardioversion Failure in Patients With Persistent Atrial...

Area of Science:

• Cardiology
• Medical Research
• Atrial Fibrillation Management

Background:

• Electrical cardioversion (ECV) is a common treatment for atrial fibrillation (AF), but 10-15% of procedures are unsuccessful.
• Predictors of ECV success are known, but the role of Body Roundness Index (BRI) remains unclear.

Purpose of the Study:

• To investigate the impact of BRI on the success of ECV in patients undergoing cryoballoon ablation for persistent AF.
• To compare BRI with Body Mass Index (BMI) in predicting ECV outcomes.

Main Methods:

• Retrospective study of 249 patients undergoing cryoballoon ablation for persistent AF.
• Patients were divided into successful and unsuccessful ECV groups.
• Analysis included BRI, BMI, left atrial diameter, and ejection fraction.

Main Results:

• ECV failed in 19.3% of patients.
• Unsuccessful ECV group had significantly higher BRI (p < 0.001), BMI (p = 0.001), and left atrial diameter (p < 0.001), with lower ejection fraction (p = 0.002).
• BRI was an independent predictor of ECV failure (OR = 29.363, p < 0.001) and showed superior discriminative performance over BMI (AUC = 0.972).

Conclusions:

• Body Roundness Index is a stronger predictor of ECV failure than BMI in patients with persistent AF.
• A BRI cutoff of 4.94 demonstrated high sensitivity (93.8%) and specificity (89.5%) for predicting ECV failure.
