ANP inhibits cardiac hypertrophy in heart failure as well as fibrosis.[1] Fibrosis is inhibited by preventing fibroblasts from entering heart tissue and replicating, as well as decreasing inflammation.[1] ANP prevents hypertrophy by inhibiting calcium influx that is caused by norepinephrine.[1]

A specific ANP precursor called mid-regional pro-atrial natriuretic peptide (MRproANP) is a highly sensitive biomarker in heart failure.[2] MRproANP levels below 120 pmol/L can be used to effectively rule out acute heart failure.[2]
