First seen Feb 24, 2026 · Last updated May 16, 2026 · Updated 7 times

Summary

This study looked at whether the aldosterone renin ratio (ARR) test can help doctors find more cases of primary aldosteronism (PA), a common and often missed cause of high blood pressure that can be cured with surgery or treated with specific medications. Researchers tested 53 adults with high blood pressure to see how many cases of PA were being overlooked. The goal is to improve detection so more people can get the right treatment.
