In 52 patients with heart failure, plasma levels of norepinephrine and epinephrine at rest were increased mainly in those patients, in whom cardiac index was depressed below the critical value of 2 liters/min/m 2.

WebbClonidine suppression testing is done by measuring plasma normetanephrine both before and 3 hours after clonidine administration. Elevated normetanephrine levels or a decrease of <40% from baseline confirms the diagnosis. The diagnosis of pheochromocytoma should be followed by studies to localize the tumor. WebbNormetanephrine is a metabolite of norepinephrine created by action of catechol-O-methyl transferase on norepinephrine. It is excreted in the urine and found in certain tissues. It …
WebbPlasma free metanephrines are up to 99% sensitive with either metanephrine or more frequently normetanephrine being elevated.
