Better breathing test could uncover hidden stroke cause
NCT ID NCT06670781
First seen May 02, 2026 · Last updated May 24, 2026 · Updated 6 times
Summary
This study tests if a more precise, goal-directed Valsalva maneuver (using a pressure gauge) finds a small heart hole called PFO better than the usual self-directed method (just bearing down). About 488 people who need a heart ultrasound after a stroke will be asked to do both maneuvers. The goal is to see which method detects PFO more often, which could help guide treatment to prevent another stroke.
