Objective To investigate the effect of adrenal surgery on blood pressure (BP) improvements in patients with hormone‐negative adrenal adenoma (HNA) concomitant with hypertension and analyze associated prognostic factors. Methods We retrospectively reviewed the clinical data of patients with HNA and hypertension and patients with aldosterone‐producing adenoma (APA) and hypertension who underwent adrenal surgery at our center between 2019 and 2022. Hypertension outcomes were evaluated in all patients and subjects were divided into three groups according to follow‐up BP and the administration of anti‐hypertensive agents: a clinical curation group, an improvement group, and a no‐improvement group. Logistic regression analysis was performed to predict factors associated with clinical curation in patients with HNA post‐surgery. Results Of the 182 patients with HNA, clinical curation was achieved in 58 patients (31.9%), improvement in 72 (39.5%), and no improvement in 52 (28.6%). The clinical curation, improvement and no improvement rates in patients with APA were 64.8% (n = 118), 15.9% (n = 29), and 19.2% (n = 35). Multivariate logistic regression analysis indicated that a duration of hypertension ≤6 years and a plasma aldosterone level >160 pg/ml were both independent factors for the clinical curation of hypertension in patients with HNA after adrenal surgery. Conclusion Adrenal surgery can cure or improve hypertension in most patients with HNA, especially in a short duration of hypertension and high plasma levels of aldosterone.
