What is A nomogram based on CHADS~2~ score for predicting atrial fibrillation recurrence after cryoballoon ablation about?

Background: As reported, CHADS 2 scoring system moderately predicts the atrial fibrillation (AF) recurrence, a common event after cryoballoon ablation. We aimed to improve the diagnostic accuracy of the CHADS 2 score by adding several routine auxiliary detection indicators into the scoring system and constructing a CHADS 2 score-based nomogram to predict AF recurrence in patients with paroxysmal AF undergoing cryoballoon ablation. Methods: Eighty-four patients with paroxysmal AF undergoing cryoballoon ablation were enrolled. Baseline characteristics were collected. The multivariable Cox proportional hazards model was used to identify the significantly related predictors of recurrence and to construct the nomogram whose performance was evaluated by the discrimination and calibration tests. Results: Thirty-five patients developed AF recurrence after a mean follow up of 19.0 ± 15.77 months. In the Cox multivariate model, CHADS 2 (>2) (hazard ratio [HR]: 2.38; 95% confidence interval [CI]: 1.14-4.98, p = .021) and albumin-to-globulin ratio (AGR) (HR: 2.49; 95% CI: 1.26-4.92, p < .008) were independent risk factors associated with AF recurrence. In addition to CHADS 2 , AGR and red bloo
