Hiperlactatemia en la ablación quirúrgica de la fibrilación auricular y cirugía cardiaca. ¿Es un factor predictivo de morbimortalidad posoperatoria?

The atrial fibrillation surgical ablation may be a not-yet-described cause of type B hyperlactatemia, with serum peak values being reached between 4-24 h after cardiac surgery. The predictive value of this elevation, its correlation with morbimortality, its sensitivity and specificity to discriminate the significant thresholds needs to be defined.
