Plasma-Free Metanephrine and Normetanephrine Quantification for Clinical Applications Validated by Combining Solid-Phase Extraction and HPLC-MS/MS [PDF]
Plasma-free metanephrines are the most sensitive and specific biochemical markers for diagnosing catecholamine-secreting tumors, such as pheochromocytoma and paraganglioma.

Urine-normetanephrine, a predictor of mortality risk in patients with adrenal adenomas [PDF]
Urine-metanephrines are used in the screening for pheochromocytomas in patients with adrenal incidentalomas, but their potential as markers for mortality in patients with adrenal adenomas has not been studied. A retrospective cohort study was designed to

Pheochromocytoma – clinical manifestations, diagnosis and current perioperative management [PDF]
Pheochromocytoma is a neuroendocrine tumor characterized by the excessive production of catecholamines (epinephrine, norepinephrine, and dopamine). The diagnosis is suspected due to hypertensive paroxysms, associated with vegetative phenomena, due to the

A hyperadrenergic state in hypertension is associated with depressive symptoms and impaired stress-modulated vasomotor responses: evidence for chronic stress as a common aetiology for a hypertension/depression phenotype [PDF]
Background Noradrenergic activation in the central and peripheral nervous systems is a putative mechanism explaining the link between hypertension and affective disorders.

Construction and validation of a multimodal predictive model incorporating catecholamines and uric acid for early detection of hypertensive organ damage [PDF]
ObjectiveTo investigate the feasibility and clinical value of constructing a predictive model for early detection of organ damage in hypertensive patients based on catecholamine-related indicators (norepinephrine, normetanephrine, and metanephrine ...
