Learning disabilities may be related to undetected hypoxia.

摘要

We read with great interest the research article by Fox et al.1 on genetic variation within defined regions of the NPPA/NPPB and NPR3 natriuretic peptide system genes as predictors for ventricular dysfunction after coronary artery bypass graft surgery. What concerns us as clinicians is the relation between those biomarkers and postoperative outcome, which can facilitate the preoperative risk evaluation. This article raised a good question: whether B-type natriuretic peptide (BNP) or its gene polymorphism predicts the prognosis in patients undergoing coronary artery bypass graft surgery.
