Latent transforming growth factor-β binding protein 4 as a biomarker of arrhythmia-induced cardiomyopathy in atrial fibrillation: insights from a high-throughput proteomic analysis
The validation cohort included 16 AF patients with LVEF <50% undergoing CA. Pulmonary vein isolation and additional ablation procedures were performed using standard radiofrequency techniques. Blood sampling was performed during CA, and proteomic profiling used SomaScan Version 4.1. At 3 months after CA, AIC classifica...
