MR-proANP refers to mid-regional pro-atrial natriuretic peptide, a fragment of the prohormone peptide secreted alongside atrial natriuretic peptide (ANP) hormone from cardiac atria. As heart atrial stretch triggers secretion, it closely mirrors ANP release, serving as a biomarker gauging hemodynamic stress.
