As far as acute ischemic stroke (AIS) outcomes in patients with nonvalvular atrial fibrillation (NVAF) are concerned, Maruyama et al. [48] reported that serum BNP levels were positively correlated both with the mRS score at 3 months and the CHADS2 score in NVAF patients, highlighting the role of BNP as an independent prognostic indicator poststroke. This evidence concerns the gene NPPB and androgen insensitivity syndrome.
