ANP elevation may mark volume dysregulation in CHF; supports mechanistic insights but leaves open diagnostic or prognostic utility.
Are plasma concentrations of atrial natriuretic peptide elevated in patients with congestive heart failure compared to matched controls?
Plasma ANP levels are significantly elevated in patients with congestive heart failure, suggesting a pathophysiological role in volume regulation.
Pettersson et al. (1986) studied this question.
