Raised normetanephrine
Webb4 okt. 2024 · Ten (31.3%) patients with CCHD had plasma normetanephrine levels elevated above the reference range, while all ACCHD patients had normal levels. Patients with lower oxygen saturation and higher proBNP had significantly higher normetanephrine levels ( ρ = −0.444, p = 0.003 and ρ = 0.449, p = 0.002, respectively). WebbThe metanephrines normetanephrine (NMN) and metanephrine (MN) are O-methylated metabolites of the catecholamines norepinephrine (NE) and epinephrine (E). The common basic structure of both molecules is the methylated catechol ring (3-methoxy 4-hydroxy phenyl) in conjunction with an ethylamine group (Fig. 1 ). Fig. 1.
