Key result
Pheochromocytoma was associated with 1.3-fold and 1.6-fold higher renin and aldosterone levels compared to essential hypertension, though these differences were not statistically significant.
Why the study?
Does excessive catecholamine secretion in pheochromocytoma activate the renin-angiotensin-aldosterone-system compared to essential hypertension?

Pheochromocytoma may activate RAAS despite nonsignificant renin/aldosterone rises; leaves open whether post-resection aldosteronism reevaluation is routinely needed.

Does excessive catecholamine secretion in pheochromocytoma activate the renin-angiotensin-aldosterone-system compared to essential hypertension?
p-value: p=not statistically significant
While pheochromocytoma is associated with high catecholamine levels, its activation of the RAAS is inconsistent and not significantly higher than in essential hypertension in this small cohort.
Haase et al. (2017) conducted a case-control in Pheochromocytoma (n=24). Pheochromocytoma vs. Essential hypertension was evaluated on Renin and aldosterone levels (p=not statistically significant). Pheochromocytoma was associated with 1.3-fold and 1.6-fold higher renin and aldosterone levels compared to essential hypertension, though these differences were not statistically significant.
