Atrial Fibrillation Recurrence Risk Factors After Cryoballoon Ablation

Clinical data and flow cytometry results for patients undergoing cryoballoon ablation for atrial fibrillation at Tianjin Medical University Second Hospital from March to November 2022. The dataset includes levels of inhibitory receptors on exhausted T cells and clinical variables used to build two predictive models for AF recurrence. The study was authored by Rong Suo and last updated in April 2026.

Use Cases

• Predicting atrial fibrillation recurrence risk based on T cell exhaustion biomarkers like KLRG1 and PD-1.
• Building a clinical nomogram for patient risk stratification using variables such as MCV, γ-GGT, glucose, and MV Vmax.
• Comparing the performance of biomarker-enhanced prediction models against standard clinical variable models.
• Analyzing the association between immunosenescence markers and post-ablation cardiac outcomes.

Strengths

• Includes novel immunological biomarkers (KLRG1, PD-1) not commonly found in standard clinical datasets.
• Models were validated using ROC curves, calibration curves, and Decision Curve Analysis.
• Data is shared under a permissive CC-BY-4.0 license.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data is from a single hospital and a short time range (March-November 2022), which may limit generalizability.
