Could hidden hormone cycles be causing Hard-to-Treat high blood pressure?
NCT ID NCT05765786
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This observational study is looking at whether people with primary aldosteronism (a cause of high blood pressure) have hormone levels that vary in cycles or differ between day and night. Researchers will collect urine samples over 24 hours from 100 participants to see if this method catches more cases than standard tests. The goal is to better understand the condition and possibly improve diagnosis.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
What this could lead to
If successful, this could improve how doctors detect primary aldosteronism, leading to better diagnosis and treatment for high blood pressure.
What could go wrong
This is an early observational study with only 100 participants, so results may not apply to everyone. It aims to understand the condition, not test a new treatment.
