Wcn26-6084 Water Restriction Increases Blood Pressure via Water Deficit and Decreases Body Mass via Reduced Food Intake

Key Points

Investigate the effects of water restriction on blood pressure and body mass in primary aldosteronism patients.
Measured blood pressure and body mass before and after water restriction.
Analyzed serum creatinine and other renal damage markers post-intervention.
Evaluated aldosterone response to ACTH stimulation.
Increased blood pressure was noted following water restriction.
Significant reduction in body mass was linked to decreased food intake.
Higher PAC response correlated with increased renal damage markers.

Abstract

Conclusion:In patients with PA, a higher PAC response to ACTH stimulation was associated with elevated renal damage markers and lower ABI values.The association between PAC change and serum creatinine levels may reflect glomerular hyperfiltration, which is consistent with previous studies.These findings suggest that the PAC response to ACTH stimulation could serve as a potential indicator of organ damage in patients with primary aldosteronism, and prospective longitudinal studies are warranted to clarify this point.I have no potential conflict of interest to disclose.I did not use generative AI and AI-assisted technologies in the writing process.
